[Abstract]:With the increasing demand of cold chain transportation, the refrigerated container transportation business expands, and the security problem in its transportation process is paid more and more attention. Therefore, it is of great significance to realize remote monitoring of refrigerated containers. Most of the existing remote monitoring schemes of refrigerated containers are only based on wired network communications or cellular mobile communications. However, because of the distribution of base stations, Factors such as signal interference make it impossible to transmit data in remote and distant sea areas. In this paper, a cold storage container monitoring terminal based on Leo satellite communication and cellular mobile communication is developed to realize the remote monitoring of refrigerated container without blind area in the whole world. The refrigerated container developed in this paper is a refrigerated container. The monitoring terminal synthetically uses the embedded technology and GPS positioning technology. Serial communication technology, low-orbit satellite communication technology and cellular mobile communication technology, with STM32 as the central processor, using GPS positioning module to collect position information and RS232 serial port to collect the information of the cooler controller. The extended sensor module collects the status information of the refrigerated container, then transmits the information packet of the refrigerated container using low-orbit satellite communication or cellular mobile communication, and finally uploads the data packet to the background data center for processing. In order to realize the remote monitoring of refrigerated container, this paper designs the power management module of refrigerated container monitoring terminal, the GPS positioning module, the data acquisition module of cooling machine, the expanding sensor module and the cellular communication module. The hardware circuit of satellite communication module, based on 渭 C/OS-II real-time operating system, using C / C to complete GPS position data acquisition program, cooling machine data acquisition program, external sensor data acquisition program, cellular communication data transmission program, The software design of satellite communication data transmission program, the function test platform of refrigerated container monitoring terminal, the hardware test and software debugging of prototype, the functional test of prototype, the reliability test of prototype, etc. It is verified that the prototype has the functions of positioning, data acquisition, cellular mobile communication and Leo satellite communication in the normal and special environment. In addition, the prototype installation test is carried out, and the results show that the prototype function is normal. To meet the requirements of development. The cold chain container monitoring terminal developed in this paper is conducive to more intelligent cold chain transport equipment, and provides a technical solution for the global monitoring of refrigerated container transport. A certain number of interfaces are reserved for the further expansion and improvement of the function of the monitoring terminal.
