研究了基于陶瓷无源无线温度传感器的无线阅读器设计,使其能够从任意方向接收一定频率范围内的温度传感器射频信号并解析为温度数据。陶瓷无源无线温度传感器是一个全新材料科学领域与无线技术领域内的新型传感器,其应答射频信号延时不超过5μs。使用MSP430FG437嵌入式低功耗处理器以及两片CC1101分别作为阅读器的核心处理器和射频信号收发端,该阅读器同时具备发射与接收无线信号的能力,在供应传感器能量的同时也接收一定能量。该硬件平台扩展接口丰富,方便新增ZIGBEE自组网、MODBUS组网等组网通信功能,非常适合某些高温高压非接触式特殊应用场合的温度监测。
The wireless reader design based on ceramic passive wireless temperature sensor is researched, which can receive the RF signal of temperature sensor in a certain frequency range from any direction and resolve it into the temperature data. Ceramic passive wireless temperature sensor is a new type of sensor in the field of materials science and wireless technology, the response RF signal delay no more than 5μs. Use MSP430FG437 embedded low-power processor and two CC1101 as a reader core processor and RF signal transceiver, the reader at the same time have the ability to send and receive wireless signals in the supply of sensor energy but also receive a certain amount of energy . This hardware platform has abundant expansion interfaces and is convenient for adding ZIGBEE ad hoc network and MODBUS network networking communication functions. It is very suitable for temperature monitoring of some high temperature and high pressure non-contact special applications.
