Currently, when applying new teaching methods, teaching integrated into vocational training institutions to train human resources to meet social needs, teaching according to each vocational skill, it is required to have adequate equipment and models. images for teaching purposes. In the Electrical Vocational Training Program: System of practical exercises, students must perform installation, inspection, operation, maintenance and repair of control systems. To perform this skill before when there was no Electrical Control Model – Automation, teachers Thai Nguyen College of Industry and Trade Having to describe on many different tables, moving from one location to another is time consuming, investing in many different desks is also costly for the school. + Stemming from the fact that school equipment has not been synchronized, some purchased devices still have some limitations: – The teacher’s pedagogical intentions have not been achieved; – There is no versatility for many lessons and many modules; – Transport difficulties; Using the model to introduce and manipulate the test, repair and connection of electrical circuits in the teaching process – High price; + Derived from the actual demand, it is necessary to add equipment to improve the quality of teaching in the condition that the school is still limited in terms of investment capital. In order to create favorable conditions for students to access advanced and modern equipment, suitable to reality and training program, the author has designed and manufactured: “Electrical control model – Automation” with purpose: – Visualization of modern teaching equipment, high technical features, safe to transport for teaching and learning; – Teaching many lessons, many modules that other devices cannot meet; – Exploit creative features of teachers and students, practice skills, approach new technologies; – Reduce investment costs to purchase equipment for the school; After having an idea The Electrical – Automation control model is integrated with equipment mounting on the practice table, applying many subject modules to help the practice process have the same field as the actual production, thereby helping For teachers to describe the operation of each detail, the system is comprehensive and realistic to help students easily think and form skills. Teachers teach on an integrated model that saves space, time, and costs for materials and accessories for students’ practice. Teaching time helps students understand the lesson faster, giving them time to practice connecting devices on the table, the model is enough to be able to work in groups. For teachers: – Explain to students the knowledge of structure and operating principle of applied electrical circuits. – Using the model to introduce and manipulate the test, repair and connection of electrical circuits in the teaching process. – With advanced exercises, teachers create incidents similar to reality for students to think, judge and propose solutions. In addition, teachers can use the device to practice skills for students – students participating in Skill Competitions at all levels and regions. Teachers can use the device to practice skills for students – students participate in Skill Competitions at all levels and regions For students: – Consolidate knowledge of structure and operating principle. – Practice checking, repairing and connecting electrical circuits separately according to each lesson in modules: basic PLC; Advanced PLC; Small-scale programming topics; Sensor engineering; Electric equipment; Electronic instruments; Electrical measurement; Basic electronics; Some technical momentum – With advanced exercises, students think, judge to find out the damage and propose remedial methods. – Through the process of practicing on the model, students can check, repair and connect actual electrical circuits. Electrical control model – Automation is used to teach theory, practice or integrated method for vocational subject modules: Industrial Electronics, Industrial Electrical and basic training part of occupations. Mechanical, Equipment Dynamics at Intermediate and College level. The model is applied with forms of concentrated training, regular training, vocational training for rural workers. Include: The novelty of the initiative New point of the model In order to help learners have access to modern technology, the author has designed an HMI screen display module to help learners implement the screen interface with the system’s operation. The HMI screen has an Ethernet port to connect to the LAN to collect data, display the operating status, warn of errors, command control of production machines, machine tools through PLC. Thanks to the HMI sensor screen interface, it is possible to simulate the working process of the system in a realistic way. At the same time, the operator can easily monitor and detect errors when problems occur and control the working system remotely through the network connection of the HMI screen. On the model, the author builds the application of PLC in mixing control controlled through the HMI sensor screen: the materials contained in tanks A and B are passed through the mixing tank by PLC programming. The PLC control device S7-200 has been upgraded to replace the PLC S7-1200 with more outstanding features such as: The S7-1200’s compact design, low cost, and powerful instruction set make the solution perfect for the application used with the S7-1200. The S7-1200 provides a PROFINET port, supporting Ethernet and TCP/IP standards. Figure 1: Difference between PLC S7-200 and PLC S7-1200 siemens Figure 2. Mixing model simulation interface using HMI . display Creative point The model mentioned that the active and active learning method of students contributes to the realization of the goal of modern education to “Train students to be dynamic, creative and independent people, to modern scientific and technical knowledge”. The model promotes activeness in students’ learning activities, puts knowledge into practice, and maximizes learners’ initiative. Apply practical skills. Up to now, teaching models usually only serve each separate module, now we have combined many modules for teaching, saving a lot of money on investment in facilities as well as time of teachers and students. born. Especially in this model, the author has incorporated intelligent control devices into teaching to help learners access the development of science and technology in daily life to serve daily life and work. his job. The initiative is worth 161,500,000 VND The beneficial value for the initiative Equipment on the market: 220,000,000 VND The author bought and assembled in 01 model by himself: VND 58,500,000 Value of benefit: 161,500,000 VND The initiative has been applied: The model after participating in the competition of do-it-yourself teaching equipment at School, Provincial and National levels in 2019 has been applied in the teaching process at schools since 2019. February 2021 has improved and continued to apply in the teaching process at the Faculty of Electrical and Automation, Thai Nguyen College of Industry and Trade, now the College of Technology and Commerce.
