The Development Of Locomotive Wireless Tele-control System Based On Microcontroller Fuzzy Control Theory

With the continuous development of science and technology, wireless remote control technology in the industrial field has been more and more applications popular. In many industries, due to the existence of the operating environment of the inevitable personal injury factors, many companies use wireless remote control technology to improve the operating conditions of the scene, and it can also liberate labor effectively, improve the productivity. Wireless remote control technology has got rid of the traditional way of industrial wiring control, which can effectively reduce the cost of investment and equipment maintenance.In this paper, based on the research of the railway transportation industry and the structure of the locomotive control circuit, a wireless remote control system based on the original electric locomotive is designed, the function of the constant speed control and the remote control locomotive are realized in this system. The system is composed of two parts of the locomotive driver's remote control (remote control) and the vehicle host (Master). Taking STM32F107VC as the core controller, the industry level BY-602 digital communication module is used as the wireless communication module.In the remote control, the key information acquisition and voice alarm circuit are designed. The fuzzy control is realized by using the look-up table method in the main control terminal, and the locomotive control driving circuit and the fault circuit are designed. The RS485 communication interface is integrated, which is convenient for the communication between the system and the computer. In the Keil MDK environment, the MCU programs of the remote control and the main control are completed by using C and assembly language.In this paper, the system analysis, fuzzy controller design, hardware structure and software design flow of the project design are introduced in detail. By debugging the system under the real condition, the disadvantage is analyzed, and the improvement suggestions are discussed.The system is stable, safe and reliable, meanwhile it is cheap and the maintenance cost is low.The remote control operation is convenient, and it can meet the needs of the scene.
