摘　　要：针对当前隧道内出现积水时无法及时上报相关部门处理从而通知司机快速重新合理规划行驶路线的情况,提出一种以MSP430单片机为核心的隧道积水量远程监控系统。采用超声波液位计输出4~20 mA电流,传送给后级单片机处理后,经无线通信模块将硬件设备与上位机客户端连接起来,实现本地与远程的数据交流,同时系统支持隧道外部的可变情报板信息显示。该系统操作方便、性能稳定、成本低,具有一定的实际应用价值。In view of the current situation that water⁃logging in the tunnel cannot be reported to the relevant department in time to deal with and inform the driver to quickly and reasonably re⁃plan the driving route,a remote monitoring system for tunnel water accumulation based on the MSP430 microcontroller is proposed.The ultrasonic level gauge is used to output 4~20 mA current,and after it is processed by the MCU,the wireless communication module is used to build a bridge between the hardware device and the upper computer client to realize the local and remote data exchange.And the system supports the information display of the variable information board outside the tunnel.The system is easy to operate,stable in performance,low in cost,and has certain practical application value.
