System For Production Status Monitoring Based On 485 Bus

Equipment Monitoring System is an important part of Enterprise Production Management, and plays an important role in ensuring the safe operation and in increasing production efficiency. First of all, several computer controlling systems were analyzed carefully and detailed compared and distribute control system was conformed. Then architectonic structure, layering structure and the function of DCS were analyzed and discussed. Scheme design for Equipment Monitoring System was made.According to the chocolate ball mill workshop’ proposed requirements of the equipment state monitoring, making sure of monitoring object and control condition, and the full analysis of the production condition monitoring system in the each part of design and function of the hardware platform. According to the design scheme of the system hardware selection, installation and commissioning; software module design.By the monitoring system features combined with centralized management and decentralized control theory and also in use of industrial machines, intelligent modules, smart instrumentation, data acquisition cards, a small distributed control system is built and the hardware and software model are established. During operation of various data signal acquisition, processing and display, industrial machines and the next crew of communication are anlysied and procedures for the preparation and site commissioning were implemented. In windows XP operating system, by using Microsoft Visual Basic6.0 high-level language for system software development is the focus of this research content. After actual commissioning the entire system to meet design performance, improved safety and production process automation.
