Cold chain monitoring system and refrigeration equipment

Abstract

The invention discloses a cold-chain monitoring system which comprises a RFID tag arranged correspondingly to each article unit in a cold chain and records the management information of the article unit, a Radio Frequency Identification( RFID) unit, a low-temperature preservation device of a communication unit, wherein, the Radio Frequency Identification( RFID) unit can read the management information stored in the RFID tag of each article unit in the low-temperature preservation device; the communication unit is used for sending information outwards, including the management information of the RFID tag of each article unit acquired by the Radio Frequency Identification( RFID) unit and the information of operational parameters of the low-temperature preservation device. The cold-chain monitoring system of the invention also comprises a remote server which is used for receiving the information sent by the low-temperature preservation device and saving the information in a database and monitoring and controlling such information. By adopting the cold-chain monitoring system of the invention, the complete information record of all article units in the cold chain during a cold-chain transferring process can be acquired. As a result, the source of the problem can be determined according to the information record when any problem occurs to the article in the cold chain.

Description

technical field [0001] The invention relates to cold chain technology, in particular to a cold chain monitoring system. The invention also provides a low-temperature storage device. Background technique [0002] Cold chain refers to the system engineering that temperature-sensitive items are always in the specified low temperature environment in all links from production to final consumption to ensure the quality of items and reduce logistics losses. It is based on refrigeration technology and based on refrigeration technology. Means of cryogenic logistics process. Cold chain is widely used in food production, but its most important application field is in medical applications. Blood, vaccines and many medicines need to be transported through cold chain. These medical supplies are related to the life and health of the people, and have stricter requirements for the entire cold chain link.

AI Technical Summary

Problems solved by technology

[0003] The existing technology lacks effective means for the management of the cold chain. At present, the main management method is to rely on manual measurement and paper records to monitor the working status of various refrigeration equipment in the cold chain; under the existing technology, barcodes have been widely used Manage items stored in the cold chain

Barcodes can identify the items in the cold chain at the item unit level, and are easy to read and identify, and can speed up the process of manual recording. However, barcode management is still only a form of manual management, and it also has various aspects of manual management. defect

[0004] First of all, the existing technology cannot realize the whole process of monitoring

[0005] Since the cold chain is long and involves multiple links such as production, transportation, storage, and consumption, manual measurement and records can only be used for data sampling at some time nodes in each link, and it is impossible to maintain full monitoring of items in the cold chain state. This makes the cold chain monitoring lack completeness, and it is impossible to find out the link and time of the problem, resulting in the failure to correct the problem in time

In the field of medicine, this situation may cause serious consequences of failure of blood, vaccines, drugs, etc.

Moreover, after these serious consequences, the existing technology is difficult to determine the responsible person

[0006] Secondly, the existing technology is not real-time

[0007] The existing technology can only be manually measured and recorded at individual time points, so that the monitoring cannot be realized during the cold chain transmission process, and the problem can only be found after the event, and the problem cannot be corrected in time when it occurs

Because a certain link in the cold chain often stores a large number of items, the problems that arise often involve a batch, causing serious economic losses

[0008] Third, the monitoring cost of the existing technology is too high

[0009] Since manual measurement and paper records are required in all links of the cold chain, it takes a lot of manpower; and the cold chain links are usually relatively long, and each link needs to be handed over. The existing management method makes the handover of adjacent links cost a lot time, reducing the circulation speed of the cold chain
