Switch Module Designed to Meet the EPS Reliability Intelligent Control

Abstract:

This paper considers the design of switch module. It is a key part of intelligent control emergency power supply. The working reliability of the switch module is an important performance index. Firstly, paper according to the characteristics that watchdog microprocessor software vulnerabilities and a control state to maintain after crash recovery, the design software reset and hardware reset propose two solutions. Next, data acquisition and data communications hardware are using photoelectric isolation technology. To achieve true electrical isolation, the system uses three power supply witch are electrically independent. And then, module data communication protocol used MODBUS_RTU, and design force control configuration software debugging interface. Finally, Experimental verification of the software programs and hardware circuit correctness and reliability. Module design reflects the improved anti-jamming capability, while more suitable for general purpose, industrialization and production.
