基于CAN总线的大豆浸油生产线监控系统的研制

Development of Monitoring and Control System for Soybean Extraction Production Line

油脂加工行业是粮食生产部门的一个重要分支,其自动化水平一直很低。针对这种情况,本文首次提出了基于CAN总线开发一套大豆浸油生产线监控系统,填补了该行业的一项空白,使产品具有先进性和通用性。论文中首先给出了系统的总体设计方案,介绍了其工作原理和工作过程。然后详细说明了智能节点中CAN通信模块的软硬件设计、基于PC机RS-232口的PC/CAN通信转换器的软硬件设计和以通用监控系统支撑软件开物2000为平台的上位机监控软件的开发。

Oil processing is an important branch of food production department. Its automation grade is very low. Aiming at this situation, the paper presents first the scheme to develop a monitoring and control system for soybean extraction production line based on CANbus, which can make up a blank of this field, at the same time can make the product advanced and current. First, the paper gives the generic design scheme, introduces its principle and working process, then discusses detailed the hardware and software designs of CAN communication module in intelligent nodes, the design of PC/CAN communication converter based on RS-232 serial port in PC, and the development of monitoring and control software on the basis of controX2000.
