Design And Implementation Of Embedded Intelligent Feed Switch Based On ARM

Mine flameproof feed switch is a critical kind of equipments in the field of coal mine power supply and distribution system , it is mainly used in the dangerous environment of coal mine which is full of hazard gas and coal dust and easy to explode to control and protect the low voltage power supply network. Its performance quality directly affects the security and efficiency of production of coal mine.In the dissertation, the construction of system network topology and hardware circuits of monitor system to intelligent feed switch are designed firstly, which according to the research of working principle of coal mine power supply. The vacuum feed switch and embedded network control system is based on EasyARM2200 which takes Philips LPC2210 as its processor and ARM7 as its kernel. Secondly, with the finish of the compilation for communication software, algorithm of protection , control on both sides of supervisor host and transplantation ofμC/OS-II to the Embedded system based on ARM7, Embedded TCP/IP protocol suites and SOCKET programming in the model of C/S are implemented and transplanted. It can fastly transmit information between supervisor host on the ground and coal mine Embedded system feed switch, and the problem of monitoring remote feed switch recirculation loop and electrical switch of coal mine by the supervisor host is resolved. Finally, an intelligent feed switch network control system which owns the functions of real-time protection and control and remote supervisory is designed.
