Problems solved by technology

[0003] At present, there are many different types of temperature indicating devices on the market, but most of them are largely restricted by external conditions in use.
For example, the temperature monitoring system based on electronic equipment (patent number: CN201382819) is generally too large in size and high in cost. If there is no external power support, it will stop working immediately
However, the applicant proposed a supercooling temperature monitoring method based on shape memory alloy (patent number: CN102944326A), although the method is simple and has high stability, it can only be used for superheating temperature detection, not supercooling temperature monitoring

Embodiment 1

[0027] A method for monitoring supercooling temperature based on shape memory alloy, which is characterized in that it comprises the following steps:

[0028] Step 1. Take 15 mg disc-shaped nickel manganese gallium as the supercooling temperature monitoring material;

[0029] Step 2. After directly pasting the nickel manganese gallium to the fitting position on the surface of the monitored product, start the monitoring of the supercooling temperature;

[0030] Step 3. After the monitoring is over, use thermal analysis equipment to analyze the supercooled temperature monitoring material, and compare the monitoring results with the original measurement results to determine whether the monitored product exceeds the minimum temperature and temperature during the monitoring process. Specific temperature information;

[0031] Step 4. Heat the said supercooling temperature monitoring material to a temperature above the austenite transformation completion temperature, so as to realize the reu...

Embodiment 2

[0034] Step 1. Take filiform titanium nickel with a weight of 10 mg as the supercooling temperature monitoring material;

[0035] Step 2. Paste the titanium nickel directly to the inner fitting position of the package box of the monitored product and then start the monitoring of the supercooling temperature; the others are the same as in Embodiment 1, and will not be repeated.

Embodiment 3

[0037] A method for monitoring supercooling temperature based on shape memory alloy, including the following steps:

[0038] Step 1. Take granular titanium nickel copper with a weight of 20 mg as the supercooling temperature monitoring material;

[0039] Step 2. Paste the titanium nickel copper directly to the outer fitting position of the package box of the monitored product, and then start the monitoring of the supercooling temperature; the others are the same as in Embodiment 1, and will not be repeated.

Abstract

The invention discloses a super-cooled temperature monitoring method based on a shape memory alloy. The method comprises the following steps: 1) taking a shape memory alloy, of which the weight is 10-20 mg and which is in arbitrary shape, as a super-cooled temperature monitoring material; 2) attaching the super-cooled temperature monitoring material directly onto the surface of a monitored product or an internal or external fit position of a package box and then, carrying out super-cooled temperature monitoring; 3) after the monitoring is finished, carrying out analysis on the super-cooled temperature monitoring material through a thermal analysis instrument, and comparing the monitoring result with an original measurement result to obtain information about whether the monitored product is lower than the minimum temperature in the monitoring process and specific temperature exceeding information; and 4) carrying out heating processing on the super-cooled temperature monitoring material until reaching a temperature higher than the austenite transformation finish temperature, so that recycle use of the super-cooled temperature monitoring material can be realized. The super-cooled temperature monitoring method does not need external power supply and can keep history temperature information for a long time.

Description

Technical field [0001] The invention relates to a temperature monitoring method, in particular to a supercooling temperature monitoring method based on a shape memory alloy, and belongs to the field of temperature monitoring and recording. Background technique [0002] As we all know, modern industrial, agricultural or pharmaceutical products need to go through a very complicated process from production, processing, and final sales. Before sales, products usually go through storage and transportation processes. However, some products, for example, Vaccines produced from proteins will fail if they are lower than the specified refrigeration temperature. Similarly, products such as lithium batteries and lubricants usually need to be stored within a specific temperature range. If improper temperature control occurs in any process, the product is most likely to deteriorate or be damaged. Therefore, in the entire supply chain of products, additional temperature indicators need to be u...
