[0002] Indoor air temperature is a fundamental parameter in building environment and energy applications. Accurate measurement of indoor air temperature is essential for various purposes, including building energy consumption monitoring, indoor environmental control, and thermal comfort analysis. Digital thermometers are commonly used for online room temperature monitoring, but they require calibration after being put into use. Currently, digital thermometers are not included in the scope of nationally mandated verification measuring instruments. Therefore, offline calibration is often used, where the digital thermometer is removed from its installation location and sent to a metrology department for calibration. This offline calibration method has the following disadvantages: 1. Although the room temperature monitoring equipment can obtain a relatively accurate compensation coefficient after offline calibration, many room temperature monitoring equipment will still exceed the tolerance under field use conditions, resulting in inaccurate room temperature monitoring. 2. Offline calibration requires a second in-home visit to disassemble and install the room temperature monitoring equipment, which disrupts the user's normal life and work, resulting in low user cooperation and high work difficulty.

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] In one exemplary embodiment, such as Figure 1 As shown, an online in-situ calibration device for room temperature monitoring equipment is provided, including a room temperature acquisition box 10 and a processing device 20. The room temperature acquisition box 10 contains multiple digital thermometers 50 with known accuracy, and these multiple digital thermometers 50 are communicatively connected to the processing device 20. Wherein: The room temperature acquisition box 50 is used to: enclose the target room temperature monitoring device inside the box, thereby isolating the target room temperature monitoring device in an independent temperature field, while simultaneously placing the target room temperature monitoring device in the same environment as multiple digital thermometers 50 with known accuracy. The target room temperature monitoring device is the room temperature monitoring device to be calibrated.

[0022] Multiple digital thermometers 50 with known accuracy are used to measure the temperature at the location of the target room temperature monitoring device when it is enclosed in the room temperature acquisition box 10 and send it as a reference temperature to the processing device 20.

[0023] Processing device 20 is used for: receiving reference temperature; The theoretical temperature value of the in-situ measurement point of the target room temperature monitoring device is calculated based on the reference temperature and used as the first sampling temperature. The difference between the first sampling temperature and the second sampling temperature is used to calculate the temperature compensation coefficient. The second sampling temperature is the measured value of the target room temperature monitoring device with the same statistical period as the first sampling temperature. The temperature compensation coefficient is used to compensate for the real-time measured temperature value of the target room temperature monitoring device. The same statistical period means that the data is collected simultaneously or the time difference between the collections is less than a preset time difference threshold.

[0024] In this embodiment of the application, when calibrating the target room temperature monitoring device, the target room temperature monitoring device is covered by the room temperature acquisition box 10, which separates the target room temperature monitoring device in the online in-situ state from the environment. This creates a relatively independent temperature field for the target room temperature monitoring device and the digital thermometer 50 with known accuracy, avoiding the problem of poor calibration results caused by other heat sources in the environment and the movement of people affecting the measurement results of the target room temperature monitoring device and the digital thermometer 50 with known accuracy.

[0025] The digital thermometer 50 with known accuracy can be a room temperature meter, temperature sensor, etc., without specific limitations; it can be selected according to actual needs. It is important to note that the accuracy of the digital thermometer must not be lower than the accuracy requirement for the calculated theoretical temperature value. For example, if the required accuracy for measuring the theoretical temperature value is not less than ±0.1℃, then the selected digital thermometer 50 must have a measurement accuracy of not less than ±0.1℃.

[0026] In another exemplary embodiment of this application, if the target room temperature monitoring device has an automatic calibration function, the aforementioned processing device 20 is a calibration controller 60, such as...

[0028] In this embodiment, after receiving the temperature compensation coefficient, the target room temperature monitoring device first stores the temperature compensation coefficient so that the temperature compensation value can be determined subsequently based on the temperature compensation coefficient. Therefore, after calculating the temperature compensation coefficient, the room temperature acquisition box 10 and the calibration controller 60 can be removed.

The calibration controller 60 receives the compensated temperature value and sends it to the calibration monitoring software platform 70. The calibration monitoring software platform 70 receives the compensated temperature value and stores and displays it so that users can view the compensated temperature value.

[0036] In this embodiment, after the calibration monitoring software platform 70 receives the compensated temperature value, the room temperature acquisition box 10 and the calibration controller 60 can be removed.

[0041] The calibration monitoring software platform 70 synchronously stores the first sampling temperature, the second sampling temperature, the temperature compensation coefficient, the temperature compensation value, the real-time temperature measurement value of the target room temperature monitoring device, and the compensated temperature data, so that users can view and track the data.

[0042] Due to equipment pricing, most room temperature monitoring devices already in use and some newly installed room temperature monitoring devices only have a measurement module but no control module. This application embodiment enables online in-situ calibration of room temperature monitoring devices with built-in control modules that have automatic calibration functions, while also being compatible with online in-situ calibration of room temperature monitoring devices that do not have built-in control modules and therefore lack automatic calibration functions.

There is no specific limit to the number of digital thermometers 50 with known accuracy inside the room temperature acquisition chamber 10; it can be set according to actual needs. For example, four digital thermometers 50 with known accuracy can be installed inside the room temperature acquisition chamber 10.

The room temperature collection box 10 is installed on the first height adjustment device 100 and the horizontal support device 120 is installed on the second height adjustment device 110.

[0054] The aforementioned position adjustment device operates to allow the room temperature acquisition box 10 to cover the target room temperature monitoring device inside the box through the aforementioned opening, and to ensure that the side of the room temperature acquisition box 10 with the opening is in close contact with the object containing the target room temperature monitoring device. Specifically, this includes: Align the opening on the room temperature acquisition box 10 with the target room temperature monitoring device. Adjust the height of the room temperature acquisition box 10 to a suitable height using the first height adjustment device 100. Move the first height adjustment device 100 until the room temperature acquisition box 10 covers the target room temperature monitoring device inside the box through the opening. Then, connect the horizontal support device 120 to the separation docking device provided on the room temperature acquisition box 10. After docking, use the horizontal support device 120 to act horizontally on the room temperature acquisition box 10 to make it fit tightly against the object where the target room temperature monitoring device is located.

[0055] The embodiments of this application do not specifically limit the structure of the first height adjustment device 100, the second height adjustment device 110, and the horizontal support device 120.

[0066] In another exemplary embodiment of this application, the room temperature acquisition box 10 is provided with a displacement identification device, which is used to monitor the displacement of the room temperature acquisition box 10.

[0067] If the room temperature acquisition box 10 is moved after installation, the positions of the multiple digital thermometers 50 with known accuracy inside the box will shift accordingly, causing the measurement results of the multiple digital thermometers 50 with known accuracy to deviate from the predetermined positions, thereby affecting the accuracy of calibration. To solve this problem, the calibration controller 60 is also used to: Before calculating the theoretical temperature value of the in-situ measurement point of the target room temperature monitoring equipment based on the reference temperature: Receive the displacement of the room temperature acquisition box 10; If the displacement of the room temperature acquisition box 10 is not zero, the position coordinates of each digital thermometer 50 with known accuracy inside the room temperature acquisition box 10 are corrected according to the displacement of the room temperature acquisition box 10.

[0114] For target room temperature monitoring devices that do not have automatic calibration functions, when using the calibration method of this application embodiment for calibration, since the calibration is performed on the real-time measured temperature of the target room temperature monitoring device on the calibration monitoring software platform 70, the target room temperature monitoring device needs to be recalibrated when it is moved from the current environment to the next environment.

When the target room temperature monitoring device exceeds the tolerance, it can be calibrated in time to ensure the accuracy of room temperature monitoring.
