摘要
基于集成温度传感器、超低功耗单片机和无线通信等技术,提出了电力电缆接头温度无线监测系统方案,并且论述了其前端装置软硬件设计。实际测试实验表明:系统可以有效监测电缆接头的温度情况,并可对具体接头超温得到早期预警信号。这对于避免电缆火灾事故,提高城市地下电缆的供电可靠性有重要意义。
The wireless temperature detection system was designed based on integrated temperature sensor,ultra-low power MCU and short range wireless communication technology.The hardware circuit and the software of temperature monitoring unit was established and discussed according to the functional requirement of the system.Having been debugged preliminary,the design of the system was tested successfully.It can not only monitor the temperature of the junction effectively,but also give early warning signal when the junction temperature is over rising,to eliminate the potential safety hazard.In terms of urban underground power cable,the application of the system can significantly avoid cable fire and improve operation reliability of power supply.
