[Abstract]:The application of prefabricated conditioning food can save the cost of the enterprise, and its production standard is uniform, and its application in the catering industry has been improved year by year. Cold chain is used to transport and store prefabricated food. The cold chain environment of food storage and food transportation is an important factor affecting food quality. Based on sensor technology, wireless transmission technology and remote terminal monitoring technology, a cold chain monitoring system based on Internet of things is developed. In the cold chain storage link, the host computer monitoring system based on distributed acquisition is designed, and the remote terminal monitoring system based on cloud service is designed in the cold chain transportation link. The purpose of information detection and visual monitoring of cold chain logistics is realized. The main contents of this paper are as follows: (1) the main environmental parameters affecting food quality in cold chain logistics are analyzed, temperature and humidity, carbon dioxide and light sensors are selected, and a kind of detecting device with C8051F380 single chip microcomputer as the control core is designed. This paper puts forward the overall scheme of the cold chain environment monitoring system based on the Internet of things, establishes the software and hardware structure of the system, completes the functional design of each component of the system, and adopts the method of distributed monitoring in the cold chain storage. Several test devices are connected to the PC by RS-485 bus, and the monitoring software of host computer is developed on the Visual Studio 2010 development platform using VB.NET technology. The functions of safe logon and exit of PC software, data display and data curve drawing, historical data viewing and warning are realized in the cold chain transportation link, combined with GPS technology, sensor technology and wireless communication technology, etc. The overall design scheme of the environment terminal of the cold chain transport vehicle is put forward, the GPS positioning of the transport vehicle is realized, and the transparent transmission function is realized through the secondary development of the ESP8266 wireless transmission module. The requirement of setting parameters on mobile terminal and detecting data in real time is realized. The remote terminal monitoring platform based on B / S architecture is developed. The system management platform of Influxdb time series database and Grafana front-end display interface is built with Ali cloud server embedded in Google Maps and the real-time location of equipment can be displayed to realize the real-time monitoring of remote terminals in cold chain system. The above research results provide a practical solution for the real-time collection of relevant information, the safe and reliable transmission of data and the intelligent monitoring and management of the cold chain system, and have certain theoretical value and application prospect.
