摘要
设计了热泵热水监控系统,介绍了MODBUS通信协议,实现了上位PC机与多台带有RS-485总线接口的智能仪表的串行通讯,达到了对现场设备的集中控制、数据采集和监视功能。实际运行证明,该系统自动化水平高,通信稳定可靠,具有较高的推广价值。
Remote monitoring system of air source heat pump unit was discussed. The serial communication between host com- puter and several intelligent instruments was realized through RS -485 bus interfaces by using MODBUS portocol. The centralized control,data acquisition,and monitoring of dispersion eqoipment were achieved. Actual operation proves the high level of automa- tion and reliable communications,making the system possesses a higher application value.
