【摘要】：食品在远程运输过程中以产生不同程度的变质,需要对食品变质信号实时采集识别,提高对食品的安全监督力度。构建基于无线传感器物联网食品变质信号采集系统,提出一种基于最小方差响应不变波束形成算法的远程运输过程中食品变质信号采集识别方法。设计基于无线传感器物联网技术的远程运输食品信号采集模型,构建食品变质信号数据传输和通信模型,对原始的食品RFID数据进行过滤,得到远程运输过程中的食品变质信号模型,有效表征食品在远程运输车中的温度、湿度和衰败性能的变化量,采用最小方差响应不变波束形成算法实现对远程运输过程中食品变质信号采集识别。仿真实验表明,采用该算法进行食品变质信号采集识别,精度较高,准确有效地识别食物变质的种类、数量和存储位置,提高了对远程运输食品的实时监管能力。
[Abstract]:Food in the process of long-distance transportation to produce varying degrees of deterioration, it is necessary to real-time acquisition and identification of food spoilage signals. To improve food safety supervision and build a wireless sensor based on the Internet of things food spoilage signal acquisition system. This paper presents a method for collecting and identifying food spoilage signals in remote transportation based on minimum variance response invariant beamforming algorithm and designs a remote transportation food signal acquisition model based on wireless sensor Internet of things technology. The data transmission and communication model of food spoilage signal is constructed, and the original food RFID data is filtered to get the food deterioration signal model in the process of long-distance transportation. Effectively characterizes the changes in temperature, humidity and decay performance of food in long-distance transport vehicles. The minimum variance response invariant beamforming algorithm is used to realize the identification of food spoilage signal in the process of long-distance transportation. The simulation results show that the algorithm has high precision in the process of food metamorphic signal acquisition and recognition. Accurate and effective identification of food spoilage species, quantity and storage location, and improve the ability of real-time monitoring of long-distance food transportation.
