Introduction
e rapid development of the information age has provided a lot of convenience for various elds, especially in teaching management, making full use of information technology can e ectively improve the quality of teaching and achieve the goal of getting twice the result with half the e ort. As the Internet grows fast, various emerging information technologies are unique and make people's lives faster and easier, such as chip technology and sensors applied in various elds, as well as cloud computing, large data and the IoT. e largescale use of various mobile devices and the constantly updated network infrastructure have brought about earthshaking changes in various elds, such as the increasingly widespread use of 4G technology, the quietly coming 5G and wide-coverage WIFI, and the widespread use of smartphones and tablet PCs. With the changing times, it also poses more severe challenges to education, especially the important link strongly relevant to the sustainable growth of higher education institutions, such as teaching and learning administration. In the background of the new information era, if the informationization of teaching and learning regulation in higher educational organizations still cannot achieve transformational development, it will cause serious constraints to the sustainable growth of higher education.
Because teaching administration information technology o ers bene ts that conventional teaching does not, teaching administration information technology can handle information and also realize information interaction.
rough informationization of instructional administration, people can create a favorable instructional environment, improve students' learning intentions, transform instructional ideas into information transmission, and ultimately promote quality of instructional management to achieve the purpose of high-quality and efficient instructional management. Based on the distributed control system, this paper studied and discussed the construction and optimization of teaching management informatization in higher vocational colleges, in order to provide a reference for the development and research of higher vocational education informatization. is article studied and discussed the building and improvement of teaching administration informatization in higher education institutions based on distributed control system, and examined the development status of education informatization in higher education institutions. Combined with the Likert scale, it was found that the average score of teachers in the basic knowledge and skills of information technology was 3.78; the overall average score of vocational teachers' informatization teaching practice was 3.59. e discussion in this regard can provide an effective reference for the peers of higher vocational college education informatization research and the further development and research of higher vocational college education informatization. e innovations of this paper are reflected as follows: (1) e construction ideas of teaching management informatization are analyzed and discussed; (2) e feasibility analysis of the teaching management system with multilayer distributed structure is carried out, and at the same time, a comprehensive evaluation of the informationization of distributed teaching management is carried out; (3) e current situation investigation and data analysis of the teaching informatization construction of A higher vocational colleges are carried out.

An evaluation of these events showed a smart adaptation of these tenets to reach learning results and discussed the implications for agile classes study [2]. Guo established the medical information management professional practice teaching quality evaluation index system, and presented an approach to evaluation in the basis of the stepwise regression method for the medical information management professional practice teaching quality evaluation index, and professional suggestions were put forward to better improve the practice teaching level of medical information management specialty [3]. In the traditional design method of university instructional administration system, the system terminal had few user rights and the security of the whole system was very low.

Lu analyzed the current case of management of physical education administration and explained the significance of data extraction skills for college physical education. en, the construction approach of the university physical education instructional administration system was proposed, and the construction approach of the physical education data extraction system and the design of the physical education database were discussed [5]. However, these scholars still lack a certain technical demonstration on the research of teaching management informatization. After research, it was found that the study on the improvement of the information construction of teaching management on the basis of distributed control systems had certain reliability. In this regard, the relevant literature on distributed control systems has been consulted.
Currently, some scholars have conducted in-depth research on distributed structures: Yang proposed an efficient distributed solution for k-NN queries for moving objects to cope with the increasingly large data scale [6]. Hashemi proposed a new two-stage method for reactive power control in power systems. In the first stage, the transport network is divided into several parts using a partitioning method based on the graph concept.

Optimization Method of Teaching Management Informatization Construction in Higher Vocational Colleges
e optimization of educational informatization must require the realization of the starting point and ultimate goal of informatization, which is to achieve the best application effect with the best organizational form and form. e ultimate goal of analyzing is to make it work at its best. erefore, in the design and selection of research objects in the research dimension, the concept of better development must be upheld, and the investigation is to propose more scientific promotion strategies. For this reason, this article studied and discussed the construction and optimization of instructional administration informationization in higher education institutions based on distributed control system.

Ideas for the Construction of Teaching Management
Informatization. With the fast growth of IT, higher institutes of occupational and technological sciences have to take the road of computerization, and the computerization of education administration is the most basic application. e informatization construction of advanced professional education depends not only on the infrastructure of informatization but also on the expansion of data, the application of data, and the formation of new ideas and concepts. erefore, the establishment of an open and shared educational resource and a cross-border educational resource is a prerequisite for realizing the informatization of educational management. e information processing system of teaching management is an essential component of the management of higher occupational and technological education. By reconstructing and optimizing the instructional administration business process, a set of instructional management information systems that can meet the needs of instructional administration and services has been established to support and guide the improvement of instructional management efficiency, management quality, and management level. For example, a teaching management resource library, a student learning resource library, a course management system, an examination management system, and a multimedia information platform, etc. can be established to open up all the teaching-related subsystems of the campus network, so that each subsystem can be used to provide services for teaching management. Figure 1 shows the management of teaching informatization construction. e informatization construction of teaching management needs to be under the guidance of the information management principle, and reform the teaching management concept in the traditional sense. In the course of construction teaching management informatization, the informatization needs of staff and students, the informatization pursuit goals and the informatization results to be achieved should be placed first in the informatization planning, such as the application of multimedia teaching content, online correction of homework, online examination, and other information-based teaching applications. As teachers, they must change their thinking, and turn the past paper-based lesson preparation to one that is supplemented by paper and mainly based on information tools, incorporate more teaching content into information-based teaching, strengthen the application and processing of existing resources, so as to relieve stress at work of teaching managers, continuously promote the quality of teaching and learning and efficiency of teachers, and improve the entire school rather than a certain manager's teaching management level, and accomplishing these tasks is the goal of higher occupational institutes to reform educational and instructional management.
e construction of teaching management informatization is beneficial to changing ideas and concepts of education, promoting teaching reform, accelerating the modernization of education and teaching, realizing modern management means, and promoting the transformation of teaching management ideas. In addition, the school management needs to change their concepts, study hard, become familiar with and master Internet technology, and apply it in various teaching management activities to truly guide the informatization development of education and teaching.

Feasibility Analysis of the Multilayer Distributed Structure Teaching Management System.
e feasibility analysis of the multilayer distributed structure teaching management system is to analyze the current actual conditions, so as to judge whether the construction of the multilayer distributed structure teaching management system can be carried out.
In the feasibility analysis of the multilayer distributed structure teaching management system, we must be careful, if there is a little mistake, it will lead to a lot of loss of human, material, and financial resources.
Usually, a feasibility analysis from three perspectives, technical, economic, and operational, must be carried out.

Technical Feasibility.
With the evolution of computing technology, the growth of multilevel distribution structure has become a promising method. From a software perspective, Windows XP is a good platform, it has strong flexibility and good security, and it can well integrate communication services.
e system is compatible with Windows XP system, and combines it with MSSQL Server 2000, making it more integrated and more consistent. JAVA uses JAVA as the development language. On the one hand, JAVA has all the characteristics of client-side development tools. On the other hand, JAVA supports data more comprehensively than other languages [14].

Economic Viability.
First, a large number of computers have been deployed in the offices and laboratories of the various colleges of the school, and at the same time, the computer network has been established. Second, the main accessories in the computer have lower price and higher Mobile Information Systems performance. erefore, the configuration of the server can be greatly improved with a very small investment, thereby further significantly increasing the total efficiency of the system [15].

Operational Feasibility.
e multilayer distributed structure teaching management system generally chooses the Windows XP style interface, and at the same time, the corresponding help can be provided to the user [16].
erefore, on the one hand, the user can be greatly facilitated, and on the other hand, the user's work interest can be greatly stimulated [17].
To sum up, it is very feasible to find, design and implement a multilayer distributed structure teaching management system. In this regard, this paper conducts a comprehensive evaluation on the informatization of distributed teaching management [18].

Comprehensive Evaluation of Distributed Teaching Management Informatization.
Comprehensive evaluation is a global and holistic evaluation of the target system of the multiattribute architecture. e basic steps of comprehensive evaluation are shown in Figure 2.
Generally, a variety of mathematical methods such as expert evaluation, economic analysis, and operations research are used for evaluation. e most commonly used method is the third type, multiobjective decision-making, AHP, fuzzy comprehensive evaluation, gray comprehensive evaluation, and so on. is paper applies a new distributedbased gray comprehensive evaluation method.

e Concrete Steps of Gray Comprehensive Evaluation.
e first stage is the choice of assessment criteria, and secondly, the weight of each indicator is calculated, and the weight of each indicator is worked out By working with a distributed analytical hierarchy procedure.
Step 3. Determine the evaluation level criteria.
Step 4. Determine the evaluation gray category. Incorporating the features of the indicators in this article, 5-level evaluation grayscale is used, which means very weak, weak, general, strong, and very strong. e corresponding whitening weight function is as follows.
e first gray class: very weak, the whitening weight function is  e second gray class: weaker, the whitening weight function is e third gray class: general, the whitening weight function is e fourth gray class: strong, the whitening weight function is e fifth gray class: very strong, the whitening weight function is Step 5. Collect expert score sheets. Provide experts with relevant information on the growth of education information technology in higher professional institutions in A province, and combine the reality of higher professional institutions on the basis of all levels in the index system, and score according to the evaluation grade standards.
Step 6. Calculate the gray evaluation coefficient. For the evaluation index c nm , the gray evaluation coefficients belonging to q evaluation gray categories are recorded as A nmq , and the total gray evaluation coefficient is A nm . e calculation formula is Among them, t nmh represents the score given by the hth expert to the evaluation index c nm .
Step 7. Construct the gray evaluation weight matrix. e gray weight u nmq of the qth gray class, By synthesizing the gray evaluation weights of the second-level indexes to which each first-level index belongs to evaluating gray classes, the gray evaluation weight matrix U n is obtained: e eighth step: comprehensively evaluate the evaluation indicators. A comprehensive evaluation is carried out on the secondary indicators, and the evaluation result is recorded as Y n : To this end, all secondary indicators Y n are evaluated, and the gray weight matrix U for the primary indicators is obtained: Among them, V n is the weight value of the first-level index obtained by the AHP.
Step 10. Calculate the comprehensive evaluation value. en the target comprehensive evaluation value X, the calculation formula is X � Y•Z D , where Z is the gray level, Z � [1 2 3 4 5].

Experimental Results
To study the development status of informatization in Class A higher education institutions more comprehensively, the survey target of questionnaire 1, that was, the development status of educational informatization in Class A higher education institutions, was 89 higher education institutions. A total of 89 surveys in all were distributed, and 89 effective surveys were received, with 100% return rate. Questionnaire 2, that was, the subject of the survey on teachers' ability of informatization instruction in higher vocational institutions, was the first-line teachers in higher vocational institutions. According to the ratio of A1, A2, and A3 higher vocational colleges: 14: 3: 5, 220 surveys were sent out in total, and 200 effective surveys were recovered.

Overview of the Professional Development of Vocational
Teachers. Of the 200 valid questionnaires returned, 95 (47.5%) were from male teachers and 105 (52.5%) were from female teachers. e age of teachers in higher vocational colleges was distributed from 25 years old to 45 years old and above, of which the higher proportion was the group of 26-35 years old and 36-45 years old, accounting for 43.5% and 39.0%, respectively. ese two groups were the main force of the teacher group, new teachers under the age of 25 only accounted for 8%, as shown in Figure 3.
Corresponding to the age of teachers was the teaching age of teachers. Corresponding to the age distribution, the proportion of teachers with teaching years of 11-20 years was 43.5%, with a total of 87 people, followed by people who had taught for more than 21 years, accounting for 28.5%. It could be seen that the teaching years of higher vocational teachers were generally longer, and the age at the time of entry was relatively young, as shown in Figure 4.
In the distribution of professional titles, the proportion equivalent to lecturers was the highest, accounting for 57.0%, with 142 people, 68 people with associate professor titles, accounting for 27.3%, and teaching assistants accounting for 11.7%. e number of teachers with the status equivalent to professors was the least, only 5 people, accounting for 2.0%, as shown in Figure 5. e construction of "dual teachers" and dual part-time status of higher vocational teachers have a significant influence on their professional teaching, so the questionnaire also investigated whether they had worked in enterprises. It was found that teachers who had never worked in enterprises or who had only 1-2 years of experience accounted for the highest proportion, the former was 78 teachers accounting for 39%, and the latter was 71 teachers accounting for 35.5%. ere were only 15 teachers who had worked in enterprises or part-time for more than 5 years, as shown in Figure 6.
Improving teachers' informatization level through network technology competition is a major measure to vigorously promote the construction of educational informatization in China recently. e results of the survey are shown in Figure 7. e situation of participation in the informatization teaching competition was polarized. e number of people who participated in the national competition was similar to the number of people who had not participated in the competition. e former accounted for 35.5%, and the latter accounted for 36%, only 1 person-time difference. e rest of the teachers who participated in the provincial and municipal two-level informatization teaching competitions were 39, accounting for 19.5%, and the number of teachers who only participated in the two-level informatization teaching competitions in colleges and universities was 18, accounting for 9%.
In the last two years, training related to informative teaching skills of the teachers tested showed that there were 56 teachers who had not received training once, accounting for 22.5%, and teachers who had once and twice accounted for 9.7% and 36.5%, respectively, the maximum number of people trained twice was 91. ere were 78 people who had been trained three times or more, accounting for 31.3%, which showed that teachers had received a relatively high number of training related to informatization teaching ability, as shown in Figure 8.

Evaluation of Teachers' Information Ability Level.
e second part of the questionnaire had a total of 20 questions, all of which were 5-point Likert scales. e research comprehensively counted the abilities of teachers from four dimensions: consciousness and attitude, foundation and skills, teaching practice, and professional practice. Each subquestion was set up with five levels of "completely disagree, disagree, uncertain, agree, strongly agree" to test the current situation of information technology teaching skills for professional teachers. e score of each option was 1, 2, 3, 4, 5 points. e following analyzed the overall results of the questionnaire from the distribution of four dimensions. e awareness and attitude of higher vocational teachers to information-based teaching were measured by the items shown in Table 1. From the perspective of vocational education, this paper examined teachers' understanding of the application of information science and technology in higher education institutions and their attitudes and trends in practical teaching. In a word, the overall score for "Application and Cognition" was 4.05, which was generally "agree," indicating a positive use of information technology across vocational schools. e basic skill level of vocational teachers' informatization teaching was investigated through the items in Table 2. e survey found that the overall score of teachers in the field of using IT and basic technology was 3.78, which was still consistent on the whole, but there was a certain deviation on the whole. Teachers as a whole had a good ability to apply information technology, but the distribution of specific abilities showed that not all teachers could effectively master the relevant technology. e practical ability of information-based teaching for higher professional teachers is the reflection of the comprehensive ability of teachers' classroom practice such as teaching preparation, teaching resource development, teacher implementation, teaching management, and evaluation. e statistical results of the survey are displayed in Table 3.
e overall average grade of the items in the informatization teaching practice of the higher vocational teachers was 3.59, and the overall mastery of the informatization teaching practice by the teachers generally had a standard deviation of 0.452 and a variance of 0.204, the overall deviation was not large, but there were obvious group differences in individual items. Among them, teachers had a good grasp of teaching preparation, media selection, and resource development, but there were great differences in the application of some specific teaching methods and the use of network tools. e "dual-professional" position of teachers in higher professional institutions and their emphasis on practical demonstration require that this study cannot ignore the 6 Mobile Information Systems important feature of "professionalization" in the investigation of their informatization teaching level. erefore, the questionnaire was designed as shown in Table 4 about the problems that higher vocational teachers would involve in teaching related to professional practice, and used this to measure present status of their professional practice. By statistics of the questionnaire results, it was found that in the information-based teaching of teachers, vocational teachers in higher professional institutes had the weakest informatization vocational practice ability, and the comprehensive score was only 3.13, which was the lowest among the four preset dimensions, indicating that most teachers had deficiencies in information technology and professional practice.     vocational colleges' education informatization construction is managed by multiple departments. Specifically, 42.9% of the informatization construction and planning administration of higher professional institutes are in charge of the modern education technology center. 21.4% of the informatization of higher vocational colleges is in charge of the graphic information center. 7.1% of the informatization of higher vocational colleges is in charge of the information network center. e informatization management department undertakes 14.3% of the informatization planning, construction, and management of colleges and universities.
In the informatization construction of colleges and universities, 14.3% have not established professional institutions for college informatization construction and planning. At present, there are several different modes of education informatization management system in higher vocational colleges, but the modern educational technology center is the main leading institution of educational informatization in higher vocational colleges. e role of the information office in higher vocational colleges in our province has not been highlighted, and the role played in higher vocational colleges is still relatively small, and the proportion of information office in higher vocational colleges is also relatively low. e institution has yet to grow and play an important role in the planning and development of educational informatization in higher vocational colleges. In addition, there are still 14.3% of higher vocational colleges that do not have a special information construction and planning department. e informatization work of higher vocational colleges is completed by each department according to the division of functions, and there is a lack of unified management and planning.
Comprehensive evaluation of education informatization in higher vocational colleges in A province: e evaluation system of the development status of education informatization in higher professional institutes in A province belongs to a distributed gray system. First, the academic evaluation study of information technology in education development is still immature, and the information on the influencing factors, hierarchical classification and index selection of educational informatization development is incomplete. Second, for the growth of education informatization in higher professional institutes in A province, some of the selected evaluation indicators and data are known and can be represented by data. However, some data are unknown, and can only be evaluated by the level of degree. irdly, there are both quantitative (whitening) and qualitative (gray) indicators in the established evaluation indicators. erefore, the research system has the gray characteristic of incomplete information. On the basis of the foregoing analysis, this Article will use the distributed gray model to evaluate the development status of education informatization in higher professional institutes in A province.
On the basis of the distributed gray evaluation system, the comprehensive evaluation values of the first-level indicators of A1 higher vocational colleges, A2 higher vocational colleges, and A3 higher vocational colleges are obtained, as illustrated in Table 5, and the consolidated assessment value of the total target is illustrated in Table 6.
From the gray comprehensive evaluation results, it can be seen that in terms of infrastructure construction, teaching informatization application, informatization management, and organizational security systems. e scores of A1 higher professional institutes are higher than that of A2 higher professional institutes and A3 higher professional institutes, and the score of A2 higher professional institutes is also higher than that of A3 higher professional institutes. However, the overall gap between A2 higher professional institutes and A3 higher professional institutes is not large. In the total score of the comprehensive evaluation, A1 higher professional institutes have the leading level of education informatization, A2 higher professional institutes, and A3 higher professional institutes rank second and third.

Conclusions
e multilayer distributed structure teaching management system must have the advantages of high security and good data confidentiality. For accurately grasping the growth status of education informatization in higher professional institutes in A province, 89 higher professional institutes in the province were investigated. By analyzing the data from the surveys, it is found that while the vocational education informatization construction in the province has achieved certain achievements, there are also the following problems: Some higher vocational colleges information planning is difficult to implement. It is difficult to share information sources among vocational colleges, and there is a Shortage of coordination and cooperation mechanism. e applied dimension of teaching informatization is low, which fails to demonstrate the advantages of a strong education province. e organizational management system of some higher professional institutes is fragmented and the operating mechanism is imperfect. e informatization guarantee  system is not well developed, and the innovation of education informatization is insufficient. In this regard, a professional organization should be established to uniformly manage the education informatization construction of various higher professional institutes. Do great work in the statistical work on the annual development of educational informatization in higher professional institutes, and do great work in the development planning of educational informatization in higher professional institutes. Establish informatization supervisors, clarify the responsibilities of informatization supervisors, improve the leadership of informatization supervisors, etc., and improve the education informatization management system in higher professional institutes. e purpose is to offer a guide to the peers of higher professional institutes education informatization research and the further growth and research of higher vocational college education informatization. Due to the limited time and research conditions, the strategies proposed in this paper are not comprehensive enough. It is hoped that it will play the role of attracting new ideas, so that more people can make suggestions for the construction and development of education informatization in higher vocational colleges.
