System for visualizing temperature tracks of cold chain logistics

Abstract

The invention discloses a system for visualizing temperature tracks of cold chain logistics. The system is characterized in that a positioning device is mounted on a refrigerator truck, so that the tracks can be visualized, and ZigBee measured temperatures are superposed on the tracks in color forms; a plurality of ZigBee temperature measurement points are arranged in a compartment of the refrigerator truck, sensed temperatures are transmitted to a ZigBee gateway, and refrigeration can be carried out in various temperature zones under the control of the ZigBee gateway according to real-time temperatures; temperature information can be uploaded to a cloud database by the ZigBee gateway, temperature data can be downloaded from cloud by a mobile terminal, the temperatures of a plurality of regions of the compartment can be displayed in a visualization manner, and accordingly 'temperature control visualization' can be implemented; the temperature tracks of the temperature zones where goods of customers are located can be acquired by mobile phones of the customers, and accordingly 'temperature track visualization' can be implemented. According to the scheme, the system has the advantages that the competitiveness of cold chain logistics companies can be improved, the throughput can be improved, and the quality of cold chains can be guaranteed; the temperature tracks of the various temperature zones can be monitored by a dispatching center via the internet, accordingly, delicacy management on the cold chains can be strengthened, and technical rectification can be timely carried out by means of big data analysis.

Description

technical field [0001] The invention relates to a cold chain logistics management system, in particular to a cold chain logistics temperature track visualization system. Background technique [0002] Developed countries have a high level of low-temperature storage technology for products, among which the refrigeration rate of meat products, dairy products, and beverages is 100%, that of fresh fruits and vegetables is 95%, and that the loss rate of products in logistics is very small, only 5%. Developed countries and regions such as Europe, America and Japan have already planned a cold chain logistics system, and a cold chain logistics temperature management system has also been established. Compared with the status quo in developed countries, China's cold chain logistics has just started, with simple refrigerated transportation equipment and extensive management. As consumers' demand for low-temperature products increases, China's cold chain logistics has a good profit marg...

AI Technical Summary

Problems solved by technology

[0006] (2) Difficulty in temperature control

If the refrigerated truck only transports goods in one temperature range, there will be a problem of low loading rate

If goods with various temperature requirements are mixed and transported, it is difficult to realize the visibility and controllability of the temperature in different temperature zones of the compartment

[0008] (3) Cold chain quality is difficult to manage

[0011] To sum up, domestic and foreign scholars mostly use GPS technology when researching vehicle monitoring, but the initiative of GPS rests with foreign companies. If China's economy relies too much on GPS, once the international environment deteriorates, it will be controlled by others.
