复杂可编程逻辑器件在磁浮列车控制系统中的应用

Application of Complex Programmable Logic Device in Control System of Maglev Vehicle

磁浮列车是人类梦寐以求的陆上交通运输工具,分为常导型和超导型二大类。叙述在常导磁浮列车悬浮控制系统中用复杂可编程逻辑器件(CPLD)实现其部分接触器的控制及相关的信号处理的功能。实践证明,CPLD的使用简化了电路设计,降低了成本,增加了电路的可靠性。

Maglev vehicle is the vehicle that people earnestly longs for, including two types that are normal electromagnetic suspension system and electrodynamic suspension system. The functions of CPLD used in the control system of maglev vehicle to control some relay and process related signal are described. The practice proved that use of CPLD predigests the design of circuit, reduces the cost and enhances the reliability of the circuits.
