摘　　要：基于PC/104的粮情监控系统由现场、过程控制层、生产管理层构成。硬件包括数据服务器、现场控制单元、低压配电柜及各种检测装置,各部件间由集线器通过CAN总线和以太网联接。软件采用WinCE组态软件,用OMT方法设计直接操作串口,发送命令的仪表驱动程序,通过DDE通信。下位机PC循环采集监测数据,预处理后送给上位机PC处理。通过CAN总线接口和以太网接口实现对监控对象的监控。Grain depot management monitor system based on PC/104 consists of field, process control level, producing control level. Hardware includes data services, LCU, lower pressure power distributing cabinet and all kind of detector equipments. All kind of components was connected with concentrator through CAN BUS and Ethernet. Configuration software of WinCE was adopted, and operates Serial port was designed by means of OMT directly. Instrument driver used to transmit order communicats through DDE. Lower PC collected monitoring data by cycle, and sends to upper PC to process after preprocessing. The management and monitoring of grain depot was realized through interface of CAN BUS and Ethernet.
