Description

Indoor temperature correction control method and system for air conditioner Technical Field The invention relates to the technical field of air conditioner control, in particular to an indoor temperature correction control method and system of an air conditioner. Background Air conditioners have become indispensable equipment in modern home and office environments, and have a core function of maintaining an indoor environment in a comfortable temperature range by adjusting parameters such as an operating frequency, a wind speed and the like. At present, most indoor units of household split air conditioners are provided with temperature sensors at air inlets for detecting indoor return air temperature, and the detected value is approximately used as the indoor environment temperature of the whole room, so that the indoor environment temperature is involved in closed-loop control of an air conditioner system. However, this control scheme, which relies on a single inlet temperature sensor, has inherent drawbacks. The temperature layering phenomenon is common in indoor space due to the influence of air physical characteristics, namely, in a heating mode, the temperature of the upper space of a room is higher due to the fact that the density of hot air is smaller and floats upwards, and the temperature of a personnel activity area (the height is about 1-5 m) is lower, and in a cooling mode, the temperature of the lower space of the room is lower due to the fact that the density of cold air is larger and sinks, and the temperature of the upper space is higher. The air intake of an air conditioner is typically mounted to the upper portion of the indoor unit at a location near the ceiling of the room. Therefore, when heating, the air inlet sensor senses the set temperature before the personnel active area, so that the control system misjudges that the room is warm enough, the running frequency or the wind speed is reduced too early, the actual heating requirement of the lower active area cannot be met, and a user feels that the heating effect is poor and the heating is slow. On the contrary, when refrigerating, the temperature sensed by the air inlet sensor is always higher than the temperature of the personnel active area, so that the control system misjudges that the room is still not cool, and therefore the air conditioner continuously operates at high power, the active area is supercooled, the user experience is uncomfortable, and the energy waste is caused. In the prior art, although an independent temperature sensor is proposed to be added indoors, the temperature sensor is mostly used for simple temperature display or single signal source switching, and the problems of how to effectively fuse the temperature of an air inlet at a fixed position with the temperature of an active area concerned by a user and perform intelligent and self-adaptive control according to different use scenes (such as refrigeration, heating, sleeping and the like) cannot be fundamentally solved. Therefore, there is a need in the art for a temperature control method for an air conditioner that overcomes the above drawbacks, and can more accurately reflect the temperature of the actual activity area of the person, so as to achieve accurate, comfortable and efficient control. Disclosure of Invention The invention aims to overcome the defects of the prior art, provides a method and a system for controlling indoor temperature correction of an air conditioner, and aims to solve the problem of inaccurate indoor temperature detection caused by fixed positions of temperature sensors of an air inlet of the existing air conditioner. In order to achieve the above object, the present application provides an indoor temperature correction control system for an air conditioner, comprising: the air inlet temperature sensor is arranged at the air inlet of the air conditioner and used for detecting a first temperature value T1; Indoor temperature sensors provided at different positions in the room for detecting a second temperature value T2i at a corresponding position i; the communication module is arranged in the air conditioner and used for establishing communication connection with the indoor temperature sensor so as to receive the second temperature value T2i; and the processor is connected with the air inlet temperature sensor and the communication module and is configured to: Obtaining a corrected indoor temperature Tc through weighted calculation according to the first temperature value T1 and the second temperature value T2 i; generating a control signal for controlling the operation parameters of the air conditioner according to the corrected indoor temperature Tc; wherein the corrected indoor temperature Tc is calculated by the following formula: In the formula, Is the weight coefficient of the temperature of the air inlet,The indoor temperature weight coefficient of the position i is that N is the total number of the positions of indoor tem
