摘　　要：运用C#编程语言开发了Modbus通信系统,实现温湿度采集。系统下位机采用具有Modbus通信功能的温湿度检测模块,多个模块通过RS485总线连接,并通过RS232-RS485转换器将通信总线连接到PC机串口。系统以Modbus协议访问每个温湿度模块,实现了多点温湿度采集。Modhus communication system was developed by using C# programming language, which took tempera- ture and humidity acquisition system as an example. Slave machine was temperature and humidity testing modules with Modbus communication function. Multiple modules were connected via bus 485, and the communication bus was connected to a PC serial port though RS232-RS485 converter. System software accessed each module with Modbus protocol. Thus multi-point temperature and humidity acquisition was achieved.
