Description

Technical Field

[0001] This utility model relates to the field of sensor calibration devices, specifically an air conditioning temperature and humidity sensor calibration device. Background Technology

[0002] Before installation, temperature and humidity sensors in air conditioners need to be calibrated, often in large batches. Traditional temperature and humidity sensor calibration is done manually, which is inefficient, time-consuming, and labor-intensive, making it unsuitable for large-scale calibration. Utility Model Content

[0003] This invention provides a calibration device for an air conditioner temperature and humidity sensor to solve the problems of poor efficiency, time-consuming and labor-intensive calibration, and difficulty in large-scale calibration of existing air conditioner temperature and humidity sensors.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A calibration device for an air conditioner temperature and humidity sensor includes a housing (1) and a calibrated temperature and humidity measuring instrument (11). Inside the housing (1) is an electric heating film (4) and several sensor mounting points (3) surrounding the electric heating film (4). Each sensor mounting point (3) is used to install the temperature and humidity sensor to be calibrated. A water inlet (5) is provided on the side wall of the housing (1) corresponding to the position of the electric heating film (4). Several fans (2) are also provided inside the housing (1). An electric control board (7) is provided on the outside of the housing (1). The electric control board (7) is electrically connected to the electric heating film (4) and each fan. The electric control board (7) is also connected to a communication bus (6). The communication bus (6) passes through the housing (1). Each sensor mounting point (3) is electrically connected to the communication bus (6). The probe of the calibrated temperature and humidity measuring instrument (11) is located inside the housing (1), and the calibrated temperature and humidity measuring instrument (11) is connected to the probe through a signal line passing through the housing (1).

[0006] Furthermore, the housing (1) is also equipped with a bracket (9), and several sensor mounting points are located on the bracket (9).

[0007] Furthermore, the bracket (9) surrounds the electric heating film (4), and several sensor mounting points (3) on the bracket (9) are evenly distributed around the electric heating film (4).

[0008] Furthermore, each sensor mounting point (3) has a communication terminal, which is used to electrically connect the communication bus (6) and the corresponding temperature and humidity sensor to be calibrated.

[0009] Furthermore, each fan (2) is circumferentially distributed at equal intervals around the electric heating film (4).

[0010] Furthermore, a display module (8) is provided outside the housing (1), and the display module (8) is electrically connected to the control board (7).

[0011] During calibration, each temperature and humidity sensor to be calibrated is installed at its respective mounting point. Water is dripped onto the electric heating film, which then heats the film, creating a suitable temperature and humidity environment inside the chamber. A fan 2 then circulates air within the chamber, ensuring a uniform distribution of temperature and humidity. Temperature and humidity data are collected by the sensors to be calibrated and transmitted to the control board. Combined with the temperature and humidity data collected by the calibrated temperature and humidity measuring instrument, the calibration of each sensor can be achieved.

[0012] This invention can create a uniformly distributed temperature and humidity field environment, effectively calibrating temperature and humidity sensors, and can calibrate a large number of temperature and humidity sensors at once. Compared with the prior art, the advantages of this invention are:

[0013] 1. This utility model has a simple structure, is easy to manufacture, and is safe and reliable;

[0014] 2. This utility model can isolate environmental interference and has a balanced and adjustable internal temperature and humidity field, making calibration more accurate.

[0015] 3. The principle of this utility model is simple and can realize the batch calibration of temperature and humidity sensors. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the structure of an embodiment of the present utility model. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown in the figure, this embodiment discloses an air conditioner temperature and humidity sensor calibration device, including a housing 1 and a calibrated temperature and humidity measuring instrument 11.

[0019] An electric heating film 4 is provided at the bottom center of the box 1. The electric heating film 4 is in a regular shape, such as a circle, and the center of the electric heating film 4 coincides with the bottom center of the box 1.

[0020] The bottom of the box 1 is provided with a bracket 9, which is circular and surrounds the electric heating film 4. The bracket 9 and the electric heating film 4 are concentric.

[0021] The bracket 9 has several sensor mounting points 3, which are evenly spaced around the electric heating film 4. Each sensor mounting point 3 includes a U-shaped component, the interior of which is used to place the temperature and humidity sensor to be calibrated. The U-shaped component is equipped with a communication terminal for electrically connecting the corresponding temperature and humidity sensor to be calibrated.

[0022] A water inlet 5 is provided at the top center of the box 1, corresponding to the position of the electric heating film 4. The water inlet 5 is used to drip water into the electric heating film 4.

[0023] Fans 2 are installed on the four sides of the interior of the housing 1, and each fan 2 is distributed in a circumferential manner around the electric heating film at equal intervals.

[0024] An electronic control board 7 and a display module 8 are installed on the outer wall of the enclosure 1. The display module 8 is electrically connected to the signal output port of the electronic control board 7. The communication port of the electronic control board 7 is connected to a communication bus 6, which extends into the interior of the enclosure 1. The communication terminals of each sensor mounting point 3 are electrically connected in parallel to the communication bus 6.

[0025] The calibrated temperature and humidity measuring instrument 11 is located outside the enclosure 1, and the probe 10 of the calibrated temperature and humidity measuring instrument 11 is located inside the enclosure 1, with the probe 10 situated within the ring area of ​​the bracket 9. The calibrated temperature and humidity measuring instrument 11 is connected to the probe via a signal cable that passes through the enclosure 1.

[0026] In this embodiment, the housing 1 and the electric heating film 4 work together to create a constant temperature and humidity field environment, so that the temperature and humidity field values ​​of the probe of the calibrated temperature and humidity measuring instrument 11 and the temperature and humidity sensor to be calibrated are the same in the housing.

[0027] Fan 2 is used to circulate air inside the enclosure 1 so that the temperature and humidity field environment is evenly distributed, thereby making the temperature and humidity field environment of each sensor installation point 3 inside the enclosure consistent.

[0028] Water inlet 5 is used to add water to the electric heating film 4. The heating film 4 continuously heats and evaporates the water to form water vapor, thereby maintaining a constant temperature and humidity inside the chamber 1.

[0029] The temperature and humidity parameters collected by each temperature and humidity sensor to be calibrated are sent to the communication bus 6 through the communication terminal of their respective sensor mounting point 3, and then sent to the electronic control board 7 through the communication bus 6. The data collected by each temperature and humidity sensor to be calibrated are transmitted centrally through the communication bus 6.

[0030] Display module 8 is used to intuitively display the temperature data collected in real time by each temperature and humidity sensor, making it convenient for operators to observe in real time.

[0031] The calibrated temperature and humidity measuring instrument 11 is electrically connected to the control board 7. The temperature and humidity data collected by the calibrated temperature and humidity measuring instrument 11 are also sent to the control board 7, and then sent to the display module 8 for display.

[0032] A small amount of clean water is dripped onto the surface of the electric heating film 4 through the water inlet 5, and then a sealing plug is placed on the water inlet 5. The electric heating film 4 heats up and evaporates to regulate the temperature and humidity parameters inside the chamber 1. The fan 2 is turned on to make the temperature and humidity field inside the chamber 1 uniform through air circulation. The probe 10 of the calibrated temperature and humidity measuring instrument 11 is inserted into the chamber 1. During the calibration process, the control board 7 reads the temperature and humidity data collected by the temperature and humidity sensor to be calibrated and displays it in real time through the display module 8. By comparing the temperature and humidity data collected by the temperature and humidity sensor to be calibrated with the temperature and humidity data collected by the calibrated temperature and humidity measuring instrument 11, each temperature and humidity sensor to be calibrated is calibrated.
