The Design of Practice Training System Based on PLC Programmable Automatic Control

Abstract

With the rise of modern industry and the rapid development of PLC, the requirement of industrial workers shift from high to high technology, gap technology talents, so that the vocational school talent training should pay attention to professional, technical and practical. As a condition of talents cultivation of hardware training equipment, can keep pace with The Times of replacement is particularly important. Based on PLC programmable automatic control system design and development, can promote technology talented person's raise produce certain. This system has played a core powerful programming of PLC control function, at the same time, the technology of sensor, electromagnetic, pneumatic, inverter consolidated, utmost ground close to the actual situation of the automatic production line, improve the simulation of this system. Introduction With the development of the microprocessor technology, the Programmable Logic Controller (PLC) is a combination of computer technology and automatic control technology developed a new kind of industrial Controller, through its internal storage procedures, to perform logical operations, sequential control, timing, counting and arithmetic operations such as user-oriented instructions, and through the digital or analog input/output control various types of machinery or production process, it will be the traditional relay Logic control technology, computer technology and communication technology, has a strong function, simple structure, convenient use, high reliability etc. [1]. After more than 30 years of development, PLC has been in metallurgy, machinery, electric power, transportation, weapon and other fields is widely used, greatly improve the automation level of the mechanical equipment and production lines [2]. As a condition of talents cultivation of hardware training equipment, and its upgrading of advancing with The Times is particularly important. Aimed at this situation, the school should adapt to social development needs, develop the corresponding professional and technical personnel, not only to let them understand and master the relevant professional knowledge, and have strong ability of problem analysis and solving ability. This system has played a core powerful programming of PLC control function, at the same time, the technology of sensor, electromagnetic, pneumatic, inverter consolidated, utmost ground close to the actual situation of the automatic production line, improve the simulation of this system. Programmable logic controller programming Main control logic part implemented jointly by controller and the programmable logic controller, the controller is responsible for receiving PC instruction and related parameters, and to achieve control of the programmable logic controller; Host controller programmable logic controller is responsible for the reception of the controller instructions and generate global clock signal and the signal, realize the infrared tubes launch logic and infrared receiving tube scan logic control [3-4]. The main control logic of the programmable logic control device of hardware implementation is shown in figure 1. Programmable logic control devices include the clock points frequency module, encode module, serial data transmission module.
