摘要
为提高温度测量效率,降低系统的成本,扩展传输距离,设计出一种新型温度采集系统。单片机通过控制具有单总线方式的温度传感器DS18B20实现对温度的测量,同时单片机通过控制具有单总线方式300～450 MHz频率范围内的MAX7044与MAX7033无线发射与接收芯片实现温度数据的无线传输。与传统温度采集系统相比,该系统利用单总线方式连接,采用无线传输方式实现远距离通信,易于系统的集成与扩展。实验结果表明,该系统结构简单、方便移植,能够同时实现多达上百点温度的测量与500 m范围的传输。
To improve the temperature measurement efficiency and reduce system cost, expansion of transmission distance, a new type of temperature acquisition system is designed.Microcontroller controlled temperature sensor DS18B20 which has a single-bus achieves temperature measurement, while microcontroller by controlled the MAX7044 and MAX7033 chip with a single-bus and having 300 - 450MHz radiofrequency to achieve the wireless transmission of temperature data.Compared with conventional temperature acquisition system,the system uses single-bus connected,and uses wireless transmission means to achieve long-distance communications, easy-to-system integration and expansion. The experimental results show that the system is simple, convenient transplantation, and can be implemented in as many as a hundred-point temperature measurement and the transmission range of 500 meters.
