据报道,武汉钢铁职工大学研制成功的粮食微机测水系统是一个分布式微机系统。用一台上位机(长城286ex微机)对测试采集的数据进行计算、处理、分析和判断,并发出控制命令,甩多台MCS—51系列的8031单片机执行分散标测和控制。系统的硬件电路自行设计了平衡传输式收发驱动器和滤波环节,有效地解决了上位机管理和下位控制机按口连接及长距离传递信息的问题,系统软件采取上位机高级语言DBASE——Ⅲ和8088汇编语言混合编程方式,合理地解决了上、下位机局的通讯联络问题,并且软件系统建有较强的文件库,使上、下位不同功能的计算机融为一体,实现了有效的管理检测和控制。
According to reports, Wuhan Iron and Steel Workers University developed a successful food computer water system is a distributed microcomputer system. Using a PC (Great Wall 286ex microcomputer) to test the collected data for calculation, processing, analysis and judgment, and issued a control command, rejection of more than one MCS-51 series of 8031 SCM implementation of distributed mapping and control. The hardware circuit of the system designed a balanced transmission transceiver driver and filter, which effectively solves the problem of upper computer management and lower controller interface and long distance transmission of information. The system software adopts upper computer high level language DBASE - Ⅲ and 8088 assembly language hybrid programming, a reasonable solution to the upper and lower bureau Bureau of communication problems, and the software system has a strong document library, the upper and lower levels of different functions of the computer integration, to achieve an effective management and testing And control.
