[Abstract]:At present, with the improvement of the awareness of food safety, agricultural products need a more perfect cold chain logistics monitoring system to ensure its quality and safety, among which the monitoring of transportation links has been the weakest link in the process of cold chain supervision. Aiming at the difficulty of cold chain transportation environment monitoring, a monitoring system based on WSN technology is designed in this paper, which realizes the real-time perception of environmental information in refrigerated cars and achieves the function of monitoring agricultural product transportation links. The main contents of this paper are as follows: (1) the research on cold chain monitoring technology at home and abroad is reviewed, and the current situation and demand of cold chain logistics process monitoring for agricultural products are analyzed. The advantages and disadvantages of various short-range wireless communication technologies and network topologies are compared. ZigBee technology and star network topology are selected to build wireless sensor networks, and the function design scheme of cold chain transportation monitoring system for agricultural products is proposed. (2) the design of sensing node and convergence node is completed. The sensing node is based on the system on CC2530 chip and the SHT15 sensor to realize the collection of the temperature and humidity information of the car, and the monitoring of the residual electricity quantity of the node is added. The convergent node is built based on CC2530 with LCD display module and serial communication module to realize data display and upload. The node software is designed with Z-Stack protocol stack, and the data collection, transmission and display are realized by optimizing the protocol stack. (3) the design of monitoring software is completed. The software of the cold chain transportation monitoring system is developed based on LabVIEW, which realizes the processing, analysis and preservation of the collected data. The warning function of the system is realized by adding the alarm module. (4) the system test proves that the monitoring system can work normally. Design node communication performance test and cold chain transport applicability test, understand the transmission characteristics of nodes in different communication frequency bands in the cold chain transport process, and provide data support for node effective deployment. The practical application shows that the node hardware has the characteristics of low cost, high integration, low power consumption, high reliability and strong stability of wireless communication, and the accuracy of collecting data in the process of cold chain transportation is high. It achieves the function of real-time monitoring and can be used in the whole process of cold chain transportation of agricultural products.
