| 摘 要： | 针对工业能源计量管理系统的实际需求,设计了基于MODBUS协议的计量数据通信系统。涡街流量计(下位机)由freescale单片机实现嵌入MODBUS协议的数据采集和显示。上位机用VB6.0编写基于MODBUS协议的程序,实现数据在上位机界面显示。并且将采集的数据值保存到SQLSever2000数据库,上下位机通过RS—485总线通讯,完成了能源计量数据的远程自动采集与管理。

| Abstract: | According to industrial energy measurement management system on account of the actual requirement, designed measurement-data communication system based on MODBUS agreement. The vortex flow-meter (lower position machine) realizes the data acquisition and the demonstration by the freescale single chip microcomputer embedded MODBUS agreement. The superior machine (PC) compiles program with VB6.0 based on the MODBUS agreement. Realize the data in the PC screen that says, and gather the data value preserves the SQLsever2000 database. Communication between the lower position machine and the PC through the RS-485 bus has completed energy measurement data long-distance automatic gathering and the management. |
