Temperature recorder in cold-chain transportation

Abstract

The invention discloses a temperature recorder in cold-chain transportation. The temperature recorder comprises a Bluetooth communication unit, a temperature sensor, and a hand-held device. The Bluetooth communication unit is used for carrying out Bluetooth communication with an external hand-held device. The temperature sensor is used for acquiring ambient temperature information. The hand-held device connected with the Bluetooth communication unit and the temperature sensor respectively is used for monitoring a temperature signal returned by the temperature sensor in real time, transmitting temperature information to the external hand-held device by the Bluetooth communication unit, monitoring whether the temperature exceeds a set value I and is smaller than a set value II in real time, sending an alarm signal to the hand-held device if so, carrying out timing simultaneously, determining the failure of the transport if the timing time exceeds set time T1, and sending transport failure information to a control unit of the external hand-held device by the Bluetooth communication unit. The recorder has characteristics of being capable of recording a transport process accurately, having an irreversible transport failure recording way, having a small, exquisite, and simple structure, and being convenient to use.

Description

technical field [0001] The invention relates to a temperature recording device during transportation, in particular to a cold chain transportation temperature recorder. Background technique [0002] There are many fields in the cold chain transportation that have extremely strict temperature requirements. For example, in the transportation of special medical supplies such as blood, the temperature requirement cannot be lower than a certain upper limit during the entire transportation process. Once exceeded, the supplies will lose their efficacy. Hazard to patient care. Or non-staple food that requires extremely strict fresh-keeping conditions. Therefore, temperature monitoring during the entire transportation process is extremely important. Market-based requirements led to the birth of temperature loggers. At present, there are many manufacturers producing temperature recorders. Although some recorder products have powerful functions, they are expensive, cannot be miniatu...

AI Technical Summary

Problems solved by technology

At present, there are many manufacturers producing temperature recorders. Although some recorder products have powerful functions, they are expensive, cannot be miniaturized, and require external power supply, which leads to a small amount in the market, and cannot be applied to some without power supply and Special occasions with strict space requirements

There is also the problem of inconvenient data reading

Sometimes have to use disposable recorder, resulting in waste
