A Device Based on the TPS61200 Wireless Temperature Measurement

通过对变电站运行设备大电流回路连接点发热原因及环境的分析,提出了一种基于ZigBee技术,结合无源温度检测电路,采用节点间歇工作方式的分布式发热检测方案。分析讨论了基于TPS61200系列DC-DC转换器解决超低电压稳定供电的方法;针对变电站恶劣的工作环境,采用无线射频和红外线双重传送模式;阐述了基于ZigBee节点技术的测温及报警电路的工作原理和实现方案,并给出了实际电路设计。最后,指出该装置可方便的应用于分布式无线测温网络系统的组成与网络构建,实现设备发热实时监控的要求。

Through the analysis of the substation equipment to run large current-loop connection point and environmental fever causes, a based on ZigBee technology, combined with passive temperature detection circuit, the intermittent use of modus operandi of the nodes distributed heat detection program has been gived. Based on analysis of the TPS61200 family of DC-DC converters to address the stability of uhra-low-voltage power supply method; substation for poor working conditions, the use of radio frequency and infrared dual-mode transmission; based on ZigBee technology node and the temperature alarm circuit The working principle and the re- alization of the program, and gives the actual circuit design. Finally, the device that can be easily applied to the distributed wireless network measurement system and building a network to achieve real-time monitoring of heating equipment.
