Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings.
The first embodiment is as follows: as shown in fig. 2, a temperature monitoring system includes a temperature sensor, a temperature monitoring instrument, and may further include a temperature calibration device.
The temperature sensor is arranged on the measured object and used for measuring temperature and outputting a temperature measuring signal. The temperature sensor is usually a thermal resistance sensor or a thermocouple sensor.
The temperature monitoring instrument is connected with the temperature sensor and comprises an interaction module and a communication module. The interaction module is connected with the temperature sensor and used for displaying the temperature measured by the temperature sensor and calibrating the displayed temperature based on the standard temperature signal. The communication module is used for realizing the communication connection between the interaction module and the temperature calibration equipment for providing the standard temperature signal.
The communication module comprises a primary communication submodule and a secondary communication submodule, the primary communication submodule is communicated with the temperature calibration equipment, and the secondary communication submodule is respectively communicated with the primary communication submodule and the interaction module. Because the temperature calibration device is usually independently arranged, the primary communication submodule is usually a wireless data transmission module capable of receiving wireless communication signals and converting the wireless communication signals into wired communication signals, and the secondary communication submodule is a wired data transmission module capable of transmitting the wired communication signals. In this embodiment, the secondary communication sub-module is an RS232 communication interface.

The temperature calibration equipment is a portable intelligent temperature measuring instrument, a handheld temperature measuring gun or a high-precision temperature sensor and the like.
When the temperature monitoring system is used, the temperature monitoring instrument collects temperature measurement signals of temperature sensors such as a thermal resistor and a thermocouple, real-time temperature values are displayed through a human-computer picture of the interaction module, and standard temperature signals containing standard temperature data sent by the temperature calibration equipment are received through the RS232 interface and the wireless data transmission module. When calibration is required, calibration is performed according to the standard temperature signal.
As shown in fig. 3, after receiving a temperature measurement signal, an interaction module of the temperature detection instrument obtains a temperature value measured by a temperature sensor and receives a standard temperature signal to obtain a standard temperature value, and then judges whether the two temperature values are consistent, if not, the temperature calibration is required, a calibration prompting interface is displayed firstly for a person to select whether to calibrate, and if the person presses an "ok" key to confirm the calibration, the temperature correction parameter and the currently displayed temperature value are automatically updated according to the two temperature values; if the person presses the exit key to abandon the calibration, the calibration is not performed, and the temperature measurement is continued.
The scheme aims at the problem of measurement errors of the temperature after the temperature detection instrument runs for a long time, realizes the function of automatic calibration of the instrument, does not need manual work and field manual work to input correction parameters of the instrument step by step like the conventional method, and only needs to select 'confirm' or 'give up' for calibration when the instrument sends out prompt calibration information, and completes the calibration work of the instrument by one key, thereby greatly facilitating the field temperature calibration work and saving a large amount of labor cost; and because the timeliness of communication data transmission, the standard temperature data measured by the calibration equipment can be almost obtained by the instrument and the calibration is completed in the first time, so that the accuracy of temperature calibration is greatly ensured.
