Description

Fuzzy control method of intelligent air supply and air conditioner Technical Field The invention relates to the technical field of air conditioners, in particular to a fuzzy control method of intelligent air supply and an air conditioner. Background Some air conditioners on the market at present have intelligent air supply (wind following or wind avoiding) functions. This function often uses radar detection function, through the position that radar module discernment current personnel were located, and radar module gives the air conditioner controller with the position transmission, and air conditioner controller control sweep blade angle realizes intelligent air supply (wind is along with the people or wind keeps away the people). However, in the actual use process, if the user experiences deviation when more than one person is present, the main reason is that when other objects (such as curtains or green plant leaves) easy to swing exist around the air conditioner, the air conditioner may swing when blowing air, and the radar may misjudge as the user. Thereby carry out intelligent air supply, influence user experience. At present, people/objects are often filtered through adding an infrared human sense function, or a radar module with higher precision is used, so that the shape of the object can be identified, and the high identification rate of the radar module to the people is ensured, but no matter which way is used, the cost is greatly increased. Disclosure of Invention Therefore, the embodiment of the invention provides a fuzzy control method for intelligent air supply and an air conditioner, which improve intelligent perception and user experience. The invention provides a fuzzy control method for intelligent air supply, which comprises the steps of obtaining a first running state of a current air conditioner when the air conditioner receives an intelligent air supply instruction sent by a control module, obtaining position information of a target object through a radar module, and controlling the running state of the air conditioner according to the intelligent air supply instruction, the position information and the first running state, wherein the intelligent air supply instruction comprises a wind avoiding person and a wind following person. Compared with the prior art, the intelligent air supply system has the technical effects that the first running state of the air conditioner is obtained when the intelligent air supply instruction is received, the state of the current air conditioner can be combined with the subsequent instruction, the implementation of the instruction is more attached to the state of the current air conditioner, meanwhile, the radar module is arranged to obtain the position information of the target object, the position of the current target object can be rapidly interpreted through the position information, better and more accurate judgment basis can be provided for the intelligent air supply instruction, the intelligent air supply instruction can better serve users, further intelligent perception is improved, and the use experience of the users is better. In one example of the invention, the method comprises the steps of controlling the air guide vanes of the air conditioner to move to a first position and controlling the air supply gear to be adjusted to a low gear after the current running state of the air conditioner is obtained, wherein the first position is the maximum wind sweeping angle of the left and right air guide vanes of the air conditioner. Compared with the prior art, the technical effect achieved by adopting the technical scheme is that the air guide blade of the air conditioner is moved to the maximum air sweeping angle, and the air supply gear is adjusted to the low air gear, so that when the follow-up detection is carried out, the objects which are easy to swing around the air conditioner are prevented from swinging due to the blowing of the air conditioner, the detection of the follow-up radar module is further influenced, the erroneous judgment is caused, the use experience of a user is influenced, and the effect of intelligent air supply cannot be reflected. In one example of the invention, acquiring the position information of the target object through the radar module comprises detecting whether the target object is a moving object, controlling the air conditioner to operate according to a first operation state if the target object is not the moving object, detecting the number of current moving objects if the target object is the moving object, controlling the air conditioner to execute a first operation mode when the number is 1, and controlling the air conditioner to execute a second operation mode when the number is greater than 1. Compared with the prior art, the intelligent air conditioner has the technical effects that whether a target object is a moving object is detected by arranging the radar module, and different control is performed on
