铁路无人值守机械室环境监控终端的改进设计

Improved Design of Environment Monitoring Terminal for Railway Unmanned Equipment Room

提出一种改进型铁路机械室环境监控终端,增加硬件终端选择模块,简化了软件设计,用数字式温湿度传感器替换原模拟式温湿度传感器,提高了测量精度、简化了电路结构和现场施工,降低了系统成本;增加网络通信接口,扩大使用场合。

This paper presents an improved environment monitoring terminal for railway equipment room. It simplifies the design of software, facilitates field construction, debug and maintenance by adding termi- nal selection module in hardware. It improves measurement accuracy, simplifies circuit structure and field construction and reduces system cost by using digital temperature and humidity sensors to replace the analog ones. It enlarges application situations by increasing network communication interface.
