Various manufacturers continue to innovate and improve air conditioning technology, and air conditioners are becoming more powerful, more energy-saving, convenient and more user-friendly.

[0003] At present, most room air conditioners mainly control the start and stop of the air conditioner by comparing the indoor temperature with the temperature set by the user (fixed-frequency air conditioners control the start and stop of the compressor in the air conditioner; variable-frequency air conditioners control the start and stop of the compressor in the air conditioner and the speed change). The position of the temperature sensor for measuring the indoor temperature of the room air conditioner is very special. Generally, a temperature probe is arranged at the protective filter of the heat exchanger of the indoor unit of the air conditioner to sense the return air temperature, and use it to replace the indoor temperature and participate in the air conditioner control cycle. Considering the utilization of indoor space, room air conditioners are usually arranged in corners away from the human activity area, and the temperature measured by the temperature probe cannot truly reflect the temperature distribution of the room, especially the temperature distribution of the space in the human activity area, and the measured temperature in the air-conditioned room cannot be automatically calibrated on site, which makes it inconvenient for the room air conditioner to accurately control the temperature in the room.

[0043] There are 2 to 3 temperature sensors 3 on the bottom surface of the remote control body 1 and they are evenly spaced.

[0044] In this embodiment, there are 2 to 3 temperature sensors 3 on the bottom surface of the remote control body 1 , and they are evenly spaced, so as to ensure the accuracy of measuring the body surface temperature of the person holding the remote control body 1 .

[0052] In this embodiment, the temperature sensor 3 is a high-precision sheet-shaped temperature sensor, which is convenient for measuring the body surface temperature of a person holding the remote control body 1 .

[0053] Embodiment 2: A method for automatic on-site calibration and precise control of the temperature of an air-conditioned room based on a temperature measuring remote controller, such as Figures 7 to 10 As shown, the following steps are included:

[0054] S1. Use the temperature measuring remote control to measure the human body surface temperature z and the ambient temperature y near the human activity area b , and the measured human body surface temperature z and ambient temperature y b The temperature is transmitted to the control processor in the room air conditioner through the wireless signal receiver of the temperature measuring remote control and the signal processor in the room air conditioner, and participates in the start and stop control of the air conditioner.

[0055] S2. Define the temperature information measured by the sensor on the room air conditioner for sensing the indoor temperature as the return air temperature x of the room, and define the room air conditioner demand temperature commanded by the temperature measuring remote controller as the set temperature t s .

[0056] S3, such as Figure 8 As shown, the steady-state situation of the room temperature distribution measured by the temperature measuring remote controller is determined. When the room air conditioner is turned off, the return air temperature x and the ambient temperature y are recorded. bThe infrared signal generator of the temperature measuring remote control is used to sense the relative position data between the temperature measuring remote control and the room air conditioner, and the relative position data is recorded and determined (the determination of the relative position data is similar to the threshold comparison. By comparing the measured relative position data with the set relative position data threshold, if the measured relative position data falls within the set threshold, it is determined that the measured relative position data is accurate, so as to avoid the inaccuracy of the measured relative position data caused by the presence of multiple remote controls of the same type or remote controls placed in unreasonable positions in the room). Then the return air temperature x is used for judgment, and the unit sliding window length is set to k. At the time j, x j ~x j+k Sample variance σ(x j ~x j+k ) changes, and set a reasonable threshold Q based on historical data σ(x) Determine whether the temperature distribution inside the room is becoming stable.

[0057] S4. Evaluate the probability that the temperature measuring remote controller is affected by the surrounding heat source by comparing the return air temperature x and the ambient temperature y. b The change trend of the return air temperature x and the ambient temperature y is evaluated by using the improved dynamic time warping method. b The two sets of data are analyzed and the threshold of the similarity distance between the two sets of data is set to Q D(xj,ybj) , and in D(x j ,y bj )<Q D(xj,ybj) When evaluating the temperature measurement remote control, the probability of being affected by surrounding heat sources is small.

[0058] S5. According to the steady-state situation of the room internal temperature distribution determined in step S3, one steady-state situation i is selected from the N steady-state situations, and at least M steady-state situations of the return air temperature x are screened out therefrom. j Samples X i and ambient temperature b At least M j Sample Y Bi , used to build a data-driven automatic correction model, where X i =(x i，1 , x i，2 ..., x i,j ,...x i,Mj ) 1×Mj , Y Bi =(y Bi,1 ,y Bi ,2...y Bi ,j...,y Bi , Mj ) 1×Mj , that is, according to all N steady-state situations involved in constructing the automatic correction model, we can get in,

[0059] S6. According to step S5, the indoor temperature measurement data is corrected. The correction process is as follows: Fig. 9 As shown, a correction function f is defined to map the return air temperature x to the corrected accurate indoor environment temperature x C Up, that is, x C =f(x), and obtain a minimized difference through the correction function f Then, the optimization algorithm is used to solve the minimized difference to complete the automatic correction process of the entire indoor temperature measurement. The optimization algorithm includes genetic algorithm, ant colony algorithm, particle swarm algorithm, etc. The optimization algorithm in this embodiment adopts genetic algorithm.

For variable-frequency air conditioners, the start and stop and speed change of the compressor in the air conditioner are controlled) to achieve precise control of the indoor ambient temperature.

[0061] The condition for determining that the room internal temperature distribution is stable in step S3 is σ(x j ~x j+k )<Q σ .

[0062] In step S4, the probability of the temperature measuring remote controller being affected by the surrounding heat source is evaluated, and the return air temperature x and the ambient temperature y are used as the input. b Evaluate x and y from the perspective of similarity measure of time series data b The consistency of data distribution and time series changes.

[0063] The method for automatic on-site calibration and precise control of the temperature of an air-conditioned room automatically corrects the original indoor ambient temperature measurement value of the air conditioner in the room based on the temperature data measured by the temperature measuring remote control, and performs intelligent control of the air conditioner according to the corrected temperature measurement value in combination with the human thermal comfort formula, thereby adjusting the start and stop of the air conditioner compressor or the change of the compressor speed, thereby achieving precise control of the indoor ambient temperature.
