利用环境余热供电的无线温度测量系统设计
Design of a Wireless Temperature Measurement System Powered by Ambient Thermal Energy
摘要
Abstract
The power supply of wireless measuring node is one of the main problems in the application of wireless measurement system. In order to solve this problem,a method is proposed to provide power for wireless measuring nodes by collecting ambient thermal energy from industrial production site and converting it into electric energy in this paper. A wireless temperature measurement system consisting of several wireless temperature measuring nodes and a Sink node is designed. The wireless temperature measuring node contains a CC2530 processor,a thermocouple temperature sensor and an energy harvest module,etc. The energy harvest module collects ambient heat by using thermoelectric chips and a power management circuit converts the output of the thermoelectric chip to a 3.3V voltage to power the wireless temperature measuring node. LTC3109 is the main component of the power management cir-cuit. A software is designed to display and save the temperature data of each measuring node received by the Sink node in real time. The experimental results show that the energy harvest module can provide power for wireless tem-perature measuring nodes under certain conditions,and provides a reference solution for the power supply of wireless measuring nodes.关键词
