Temperature accurate acquisition method for cold chain temperature recorder

Abstract

The invention relates to a temperature accurate acquisition method for a cold chain temperature recorder. The temperature accurate acquisition method for the cold chain temperature recorder comprises the steps that (1) a controlled area is delimited, and temperature collectors are suspended at different positions above the controlled area; (2) the temperature collectors acquire the real-time temperature data of the controlled area, and then the real-time temperature data of the controlled area are transmitted to a database and are compared with data in the database; (3) a temperature acquisition system displays the temperature of the controlled area or gives an alarm automatically according to a comparison result. According to the temperature accurate acquisition method for the cold chain temperature recorder, due to the fact that the temperature collectors are in contact with no object in the controlled area, the accuracy of each temperature collector is guaranteed; in addition, due to the fact that display can be conducted correspondingly or an alarm is given correspondingly according to different monitoring conditions, accurate acquisition of the temperature of the controlled area is achieved.

Description

Technical field [0001] The invention relates to a temperature collection method, in particular to a method for accurately collecting temperature for a cold chain temperature recorder. Background technique [0002] In cold chain logistics, the real-time temperature of materials is a very important control parameter in the transportation process. How to objectively, conveniently and accurately provide the real-time temperature value of items in the entire logistics process has become a new research topic in cold chain logistics. There are also some temperature measuring instruments that can measure the temperature of materials, but there are two common problems: 1. The measurement accuracy of conventional thermocouples is not high, and the measured temperature value fluctuates greatly; 2. It cannot reflect the historical temperature value during transportation. And provide credible printing data; 3. Can not reflect which point of the entire controlled area has a temperature problem...

Now there are also some temperature measuring instruments that can measure the temperature of materials, but there are two common problems: 1. The measurement accuracy of conventional thermocouples is not high, and the measured temperature value fluctuates greatly; 2. It cannot reflect the historical temperature value during transportation. And provide credible printing data; 3. It cannot reflect the temperature of which point in the entire controlled area has a problem
