Embodiment Construction

[0025] refer to figure 1 , this figure is a composition structure diagram of an embodiment of the temperature calibration system provided by the present invention; When, the host computer can be a host computer or a machine with a function similar to a host computer; the device under test is a hair straightener. Among them, the upper computer 1 is set with:

[0026] The main control unit 11 is used to send the set temperature value to the device under test, and calculate the difference between the actual temperature value of the surface of the device under test and the set temperature value, and send the difference to the device under test;

[0027] The temperature acquisition unit 12 is connected with the main control unit 11, and is used to collect the temperature value of the device under test after the surface temperature reaches a stable value, and transmit the temperature value to the main control unit 11. During specific implementation, it can pass Link to the main co...

Abstract

The invention discloses a temperature correction system and method. The system comprises a host computer and one or more tested devices. The host computer is provided with a main control unit for sending a set temperature value to one tested device, calculating the difference value of the actual temperature value of the surface of the test device and the set temperature value and sending the difference value to the tested device, a temperature acquisition unit, namely an infrared temperature sensor, for acquiring the temperature value of the tested device when the surface temperature of the tested device is stable and sending the temperature value to the main control unit, and a wireless signal transmission unit for transmitting the set temperature value of the main control unit and the difference value to the tested device. The tested device is provided with a temperature adjusting unit for adjusting the heating power according to the set temperature value from a host computer so that the surface temperature reaches a stable value, and a storage unit for storing the difference value of the set temperature and the surface actual value. The temperature correction system and the method can eliminate the temperature differences for small household appliances caused by the influences of parameter errors of parts of a controlled panel and the errors of assembling factors and the resistance value of a heating element.

Description

technical field [0001] The invention relates to temperature adjustment technology, in particular to a temperature calibration system and method. Background technique [0002] At present, many small household appliances that work at high temperatures are used in people's daily life. Since these small household appliances work at a high temperature, for safety considerations, it is necessary to accurately control their working temperature. Taking the hair straightener as an example, in order not to cause damage to the hair during the use of the hair straightener, when the temperature is close to the set temperature, it is necessary to perform PID adjustment on the heating power of the hair straightener to gradually reduce the heating power. This makes the temperature more stable. [0003] However, affected by the parameter error of the product control board, assembly factors, and the error of the resistance of the heating element itself, it is difficult to make the temperatur...
