Embodiment 1

[0047] Such as figure 1 As shown, a wireless temperature measurement and correction device includes a temperature sensor, a temperature switch, a main controller and a wireless communication module. The wireless communication module in this embodiment may be a WIFI module, a GPRS module, a 3G / 4G module, and the like.

[0048] The temperature switch is used to generate a first interruption signal when the temperature of the measured object reaches the action temperature, and generate a second interruption signal when the temperature of the measured object reaches the recovery temperature. That is to say, if the temperature switch is a normally open switch, when the temperature reaches the operating temperature, it will be closed, and when the temperature returns to the recovery temperature, it will be opened. The action temperature and recovery temperature of the temperature switch are fixed, which can be stored in the memory of the main controller in advance.

[0049] The main...

Embodiment 2

[0063] The difference between this embodiment and Embodiment 1 is that the temperature sensor has computing capability, and the calibration parameters are stored in the temperature sensor. details as follows:

[0064] A wireless temperature measurement and correction device, which includes a temperature sensor, a temperature switch, a main controller and a wireless communication module;

[0065] The temperature switch is used to generate a first interrupt signal when the temperature of the measured object reaches the action temperature, and generate a second interrupt signal when the temperature of the measured object reaches the recovery temperature;

[0066] The main controller is used to obtain the temperature value T1 of the measured target through the temperature sensor when receiving the first interrupt signal, and record the corresponding action temperature as T11; when receiving the second interrupt signal, pass the temperature The sensor obtains the temperature value...

Abstract

The invention discloses a wireless temperature measurement and correction device and method. The device includes: a temperature switch, which is used to generate a first interrupt signal when the temperature of the measured object reaches the action temperature, and generates a second interrupt signal when the temperature of the measured object reaches the recovery temperature; When the first interrupt signal is received, the temperature value T1 of the measured target is obtained through the temperature sensor, and the corresponding operating temperature is recorded as T11. When the second interrupt signal is received, the temperature value T2 of the measured target is obtained through the temperature sensor , and record the corresponding recovery temperature as T22, according to T1, T2, T11 and T22, calculate the correction parameters through the preset formula, and calculate the correction temperature according to the correction parameters and the real-time temperature value collected by the temperature sensor in real time value; a wireless communication module, configured to send the corrected temperature value and / or the first interruption signal to an external receiving terminal. The invention can solve the problems of false alarm and inaccurate temperature measurement.

Description

technical field [0001] The invention relates to a wireless temperature measurement and correction device and method. Background technique [0002] The wireless temperature sensor currently used in the industry mainly collects the temperature of the contact or non-contact temperature sensing device through the main control module at a fixed interval, and then transmits it to the receiving host through the wireless module, and the receiving host locally displays the temperature and makes an alarm judgment. Or the receiving host uploads to the background software for display and alarm. [0003] The above-mentioned conventional scheme main control acquisition temperature-sensing device is susceptible to electric field interference, which leads to inaccurate temperature measurement and transmission to the host, causing false alarms or no alarms. [0004] Regardless of contact temperature measurement or non-contact temperature measurement, the temperature measurement may be inacc...
