摘要
MODBUS协议由于得到众多仪表厂家的支持,正在成为仪表及智能终端的工业标准。所设计的减速器监测系统以AT89C55WD单片机为核心处理器实现对传感器采集的减速器油温、油位、冷却水压力、流量等信号处理、显示。采用了MODBUS通信协议设计减速器监测系统的通信程序。选用MAX485来完成单片机与上位机之间通信的接口芯片。给出了基于MODBUS通信的软件流程图及部分软件程序。
MODBUS protocol is becoming the standard of meter and intelligent terminal, because it is supported by many meter manufacturers. It adopted AT89C55WD as the core to design the system for monitoring the temperature and height of the oil, plus the pressure and the flow quantity of the cooling water; adopted the MODBUS protocol to design the communication program of the system. The interface chip of communication was MAX485. The flow chart of the communication program and some program based on MODBUS protocol was provided.
