摘要
针对冷链运输监测集中监管、局域分布和整体流动的特点,设计冷链运输监测系统。重点介绍以STM32微处理器为控制核心的数据汇转模块,以及针对冷链运输环境而设计的基于SX1212芯片的无线模块的无线自组网络。该系统能有效监测温/湿度、电池电量和行车路线信息,减少了物流损耗。与ZigBee方案相比,该方案的功耗更低。
Aiming at the centralized supervision,local distribution and overall mobility, a cold chain transportation monitoring system was designed; and STM32 microprocessor-cored data transfer module and Ad Hoc network of SX1212 chip-based wireless model for the cold chain transportation were introduced specially. The system can monitor temperature and humidity,battery capacity and transit route so as to reduce transportation loss; and compared with ZigBee scheme,this scheme has lower power consumption.
