摘　　要：青岛某再生能源公司为焚烧生活垃圾并发电,建立了1套有2台地磅的车辆自动称重系统,2台计算机读取地磅称重仪表中的数据,通过企业局域网传输到数据库服务器。焚烧发电的控制系统为DCS。在厂区内数据库服务器与DCS相距1.5 km,距离较远。为方便企业远程监控和统计入厂的垃圾量,设计了车辆称重数据远传DCS的系统,由光纤电缆实现通信。基于Modbus-RTU协议,利用Visual basic 6.0在数据库服务器上开发与DCS通信的程序,提取数据库中称重记录的有用信息,通过RS485串口将其远传至DCS。目前该系统已经投入使用,实际运行平稳、可靠,为企业获得政府政策性资金支持提供了数据支持。A renewable energy company in Qingdao has set up a vehicle automatic weighing system with two weighbridges for burning domestic waste and generating electricity,and two computers read the data in the scale weighing instrument and transmit it to the database server through the enterprise LAN.In the factory,the distance between the database server and DCS is 1.5 km,which is far away.In order to facilitate the enterprise to monitor and count the amount of garbage in the factory remotely,the vehicle weighing data remote DCS system is designed,and the communication is realized by optical fiber cable.Based on Modbus-RTU protocol,Visual basic 6.0 is used to develop the program of communication with DCS on database server,extract the useful information of weighing record in database,and transmit it to DCS via RS485 serial port.At present,the system has been put into use,running smoothly and reliably,providing data support for enterprises to obtain government policy funding support.
