Temperature calibration method and system

Abstract

The invention provides a temperature calibration method and system. The method is applied to a temperature calibration system. The system comprises a temperature calibration transmitter, an outdoor temperature transmitter and an indoor temperature receiver, the temperature calibration transmitter, the outdoor temperature transmitter and the indoor temperature receiver are all arranged in a shielding room; the indoor temperature receiver is in communication connection with the temperature calibration transmitter and the outdoor temperature transmitter. The method comprises the steps that a temperature calibration transmitter transmits first current temperature data to an indoor temperature receiver, so that the indoor temperature receiver carries out temperature calibration on the indoor temperature receiver according to the first current temperature data; and the outdoor temperature transmitter transmits the second current temperature data to the calibrated indoor temperature receiver, so that the indoor temperature receiver performs temperature calibration of the outdoor temperature transmitter according to the first calibration temperature data. According to the method, only one shielding room is needed, constant-temperature facilities are not needed, the calibration cost is low, calibration steps are few, operability is high, operation efficiency is high, and batch operation is easy.

Description

technical field [0001] The present application relates to the technical field of temperature calibration, in particular to a temperature calibration method and system. Background technique [0002] The current temperature detection products, which require high temperature detection accuracy, generally carry out temperature calibration. For patch-type temperature sensor products such as outdoor temperature transmitters and indoor temperature receivers, calibration is required due to large errors in patch-type temperature detection devices. [0003] For outdoor temperature transmitters with no display and no buttons, how to calibrate the temperature has always been a difficult problem. Since the outdoor temperature transmitter has no temperature data display and calibration operation buttons, it cannot be calibrated directly with standard temperature. At present, for outdoor temperature transmitters and indoor temperature receivers, it is generally necessary to use a constant...

Problems solved by technology

Due to the high operating cost of the constant temperature room or the constant temperature box, the investment cost is very high, and the effect is not necessarily good. It is necessary to record the data and classify them, and burn the software with different bias temperatures on the spot. The operation process is complicated, and it is difficult for the operator The requirements are too high, the efficiency is low, and the mass production is low
