Problems solved by technology

This method takes a long time to test, and the range of temperature control is small. In the case of limited experimental equipment, it is limited by the experimental time and various conditions, which is not conducive to making full use of the experimental equipment.
With the development of the Internet, the use of computer software to remotely control experimental equipment for experimental operations is becoming more and more widespread, but it is rare to use the Internet to remotely measure the Seebeck coefficient and resistance of thermoelectric materials. In the instrument control system, there are the following shortcomings: (1) The upper computer software uses VB, VC, etc. for programming, the data processing ability is weak, and the professional degree of the experiment or control interface is not high; (2) Most of them do not contain identity authentication and experiment records function, which is not conducive to widespread promotion and use

Description

technical field [0001] The invention relates to a remote measuring device for Seebeck coefficient and resistance of thermoelectric materials and an application thereof, belonging to the technical field of electrical testing and measuring equipment. Background technique [0002] Thermoelectric materials are functional materials that can convert thermal energy and electrical energy. The Seebeck effect discovered in 1823 and the Peltier effect discovered in 1834 provide a theoretical basis for the application of thermoelectric energy converters and thermoelectric refrigeration. The Seebeck effect, also known as the first thermoelectric effect, refers to the thermoelectric phenomenon of the voltage difference between two substances caused by the temperature difference between two different electrical conductors or semiconductors. The essence of the Seebeck effect lies in two When metals are in contact, a contact potential difference is generated, which depends on the two basic f...
