基于VxWorks和MC68332的变电站测控系统驱动程序设计

Driver design of measurement-control system of power substation based on MC68332 and VxWorks

本测控系统中采用具有32位CPU的MC68332作为主控微机,下级采集节点采用80C196以采集变电站的遥信量与遥测量。同时应用嵌入式实时多任务操作系统VxWorks。设计了主控微机与采集节点之间交互的CANBUS驱动程序以及主控微机与后台连接的以太网驱动程序,并简单叙述了系统的flash的管理方案。通过应用证明本系统不仅满足电力系统的要求,与常用的电力自动化设备相比还具有成本低,占用空间小的优点。

In this measure-control system, MC68332 with 32 bit CPU is used as master and 80c196 is used as slave port to collect remote measurement data and remote signals of switch in power substation. And the embedded, real-time and multi-task OS, VxWorks is used. The CAN BUS driver by which master micro-computer can interactive with slave is designed.And Ethernet driver which used to link master micro-computer with backstage management computer is designed too. It has been tested by application that the measure-control system is not only can satisfy the power system, but also has merits of low cost and small size compares with ordinary automatic equipment for power system.
