摘要
针对城市热网实时监测困难,便捷高效、远程温度监测设备短缺等突出问题,将远程通信及红外测温技术应用于热网温度监测中,设计了一种基于GPRS通信技术的热网红外测温系统。以MLX90614红外测温传感器获取热网观测点的温度信息并传输至低功耗单片机MSP430F169做解码处理,采用GPRS通信模块SIM900A,将解码数据发送至固定管理平台或移动管理终端,实现对监测点的远程监测,多点布控可实现多点监测。同时,每个监测终端可实时显示测温结果,便于现场观测与维护。测试实验表明,该系统温度信息采集准确、数据传输稳定,可满足目前城市热网实时远程监测的需求。
For the prominent problems that the city heat-supply network is hard to monitor in real-time and lacks of the convenient and efficient remote temperature monitoring equipment,the infrared temperature measurement system for heat-supply network based on GPRS communication technology was designed by combining the remote communication with infrared temperature measurement technology. The temperature information of the heat- supply network observation point is acquired by means of MLX90614 infrared temperature sensor,and transmitted to the low-power consumption microcontroller MSP430F169 for decoding. The decoded data is sent to the fixed management platform or mobile management terminal by GPRS communication module to realize remote monitoring of the observation point. The multi-point monitoring can be realized by multi-point deploy and control. Each monitoring terminal can display the temperature measurement results in real-time,which is convenient for field observation and maintenance. The testing experiment results indicate that the system can perform accurate temperature information collection and stable data transmission,which can satisfy the need of real-time remote monitoring for city heat-supply network.
