摘　　要：针对当前土壤环境参数采集系统可扩展性低、实时性差、数据可靠性不高等问题,设计并实现了基于JSON数据格式的感知源信任评价的土壤环境参数实时无线采集系统。系统以CC2530芯片为ZigBee组网核心,以STM32为MCU,选取适合土壤环境的温度、湿度、光照强度等环境参数,相对于传统的土壤环境参数采集模块,系统的创新点在于使用JSON刻画了土壤环境参数;另一方面,环境监测过程中每路数据参数均由3路传感器同时工作,并基于感知源信任评价的可靠数据保障模型计算出一个可靠的数据和传感器状态。实验结果表明,系统工作正常,数据采集传输存储正确率高达90%以上,感知源信任评价的可靠数据保障模型的引入提高了系统的数据可靠性。JSON传感资源描述方法的引入,使其他类型的传感设备能够很便捷地引入到系统中,提高了物联网系统的灵活性和可扩展性。Aiming at the problems of low scalability,poor real-time performance and low data reliability of current farmland soil environmental parameter collection system,an IOT(Internet of Things)system based on perceptive source trust evaluation is designed and implemented.The system takes CC2530 chip as ZigBee network core and STM32 as MCU to collect environmental parameters such as temperature,humidity and light intensity.Compared with the traditional soil environmental parameter acquisition module,the innovation of this system lies in using JSON to characterize the soil environment parameters.In addition,in the process of environmental monitoring,each data parameter is operated by three sensors simultaneously,with a reliable data and sensor state calculated by the model.Experimental results show that the system works normally and that the accuracy rate of data acquisition,transmission and storage is up to 90%.The introduction of JSON sensor resource description method enables other types of sensor devices to be easily introduced into the system,improving the flexibility and expansibility of the IOT system.
