Is a computer technology, automation technology, communications technology is one of the new control device. Its superior performance, has been widely used in various fields of industrial control. In the power industry, the application of programmable controllers occasions abound. Such as power plant coal handling system, boiler combustion system, turbine and boiler starting and stopping the system, waste water treatment system Generator And Transformer Monitoring system, the entire power grid interconnection communication, scheduling and control, programmable controllers dynamic control, and so soft. As a Vocational Technical College, in teaching students to master the most advanced of modern automation and control technology to meet the power system as well as social enterprises need highly skilled personnel is necessary. Wuhan Institute of Electric Power Engineering, Technology & Utilization Technology Department of the spirit of "service for the purpose of employment-oriented, competency-based" concept of vocational education in schools, and Hubei Huamao jointly developed the Electrical and Mechanical Engineering, developed PLC Industrial Control Training System (Figure 1), focusing on practical, taking into account advanced, versatile, and strive to create industrial field environment and to create industrial atmosphere, which consists of Industrial Control Systems And production equipment used in the scene exactly the same as the first case in China. Has aroused the concern of the relevant departments. The device has been Omron Automation (China) governs application of the Group as CP1H example posted on the China Electrotechnical Society, "Training" book publicity plan. 2 Introduction Greatest feature of the training system is on the student's training can be implemented progressively from easy to difficult, subtle control of the design object, the students experiment (training) played a very good results. Training system is the latest Japanese Omron Corporation, the most advantage of the PLC?? CP1H-40CDR-A as the main control center, also with Touch Screen , Inverter , Temperature controllers, control with communications equipment and industrial site commonly used Sensor , Rotary encoders, proximity switches, etc., the system also has one of the most lower-phase Motor , A DC motor and a heater control object. Items from the most basic PLC training program, inverter, temperature controller and a separate touch screen practical training (including the control object), the gradual deepening and 485 through the RS232 port to communicate with each other between the various devices to form a closed loop control system. Programmable logic controller from the host can accurately handle sensor, timer, thermostat, switches and other control components of the information, effective control of the operation of machinery and equipment. A programmable controller as the center, with a programmable touch-screen terminals to facilitate the control of the production of objects and parameters of change, as the equipment operator and human-computer interaction interface, in improving the production efficiency can play an important role. In the industrial control field, a variety of production equipment, controller and intelligent Instrumentation So often at the factory, workshop of different places, how to connect these control devices to complete the on-site real-time collection of information, communication and real-time control of equipment, monitoring, and remote maintenance; how to plant at different locations on the PLC and PLC, PLC and computer or PLC and intelligent devices connected by the transmission medium to achieve communication, to form more powerful, better performance of control systems, etc. These are all factory automation network problems. According to the actual situation of industrial field, the training system also has a strong network communication configuration training for students with: the top with Ethernet (Ethernet) to achieve high data transfer, makes the PLC Ethernet module can be used as Factory LAN node on the network any computer can achieve its control. Ethernet communication module and the host computer communication, to achieve the monitoring PC operation, while by Fieldbus Module DRM21 PLC and PLC to achieve data sharing between. SCU serial communication module and the third-party devices such as DCS , Boiler and other communications, to create a remote monitoring environment; middle control layer network (ControllerLink), is introduced OMRON FA (Factory Automation) field used in PLC, the computer and the PLC to exchange large amounts of data between the network and the computer also can be used as a node on the PLC to monitor, run the configuration software programming; last through the device layer network (DeviceNet) to achieve control equipment on the bottom of the remote control. Students PLC Industrial Control Training System through training, strengthening the comprehensive practical ability, to improve students ability, provide favorable conditions. Enhance the adaptability of the students on the job, shortening pre-service training time ("zero distance" skilled personnel), so useful for students to truly become a highly skilled business talent has a unique role.
