摘要
济钢信息化的智能仪表采集系统选用Mox公司的MoxRTU采集网关,采用MoxIDE和MoxGRAF作为系统软件,通过485通讯,应用平衡发送和差分接收的方式进行数据读取。系统的每个串口采用两根信号可连接仪表480块,对标准Modbus通讯和非标准自由口通讯协议仪表都可实时读取。该系统具有通用性强、成本低、采集范围广的特点,系统投用后,运行稳定,数据精确,采集数据刷新率达到秒级,节省了人力、物力,是济钢信息化的有力数据支撑。
MoxRTU acquisition gateway of Mox company and MoxIDE and MoxGRAF system software are adopted for data acquisition system of the intelligent instruments of Jinan Iron and Steel Group. By the 485 communication,data are collected through the methods of balance transmission and difference reception. For the standard Modbus communication and non-standard free port communication protocol instruments,data can be read by two signal lines for each serial port of the system which can be simultaneously connected 480 instruments. The system with the characteristics of strong universality,low cost,wide acquisition range,system performance is stable and data is accurate,and the second level data update can be accomplished. It is reliable data support for information and can improve the management level of the enterprises and save manpower and material resources.
