Problems solved by technology

[0002] At present, household air conditioners are widely used, and most of the air conditioners shut down the air conditioner by entering the sleep mode through the remote control. After the user falls asleep, the pores are in a relaxed and open state, and it is easy to catch cold. Once the cold occurs, the body's resistance tends to decline, which is likely to endanger the user's health

Embodiment 1

[0046] Example 1, please refer to figure 1 , figure 1 This is the flow chart of the air conditioner detection intelligent shutdown shown in the embodiment of the present application.

[0047]When the air conditioner is turned on, based on the communication with the built-in WIFI module of the air conditioner, the air conditioner terminal acts as the STA terminal, and the router or other central controller carrying the WIFI module is the AP terminal. The STA obtains the WIFI channel status between the STA and the AP terminal by requesting the AP terminal. Information (CSI), the channel state information includes: information between N sub-carriers, normally 56 sub-carriers can be obtained through OFDM under the 802.11n standard, and the information between sub-carriers is specifically the signal amplitude, phase and frequency, etc. information; changes in the amplitude and phase of the sub-carriers caused by human movement, the changes in the amplitude and phase between the su...

Embodiment 2

[0053] Embodiment 2, when it is detected in a sleep monitoring cycle that the user is not asleep, in order to further eliminate the interference caused by external factors such as outsiders opening the door and coming in during the sleep monitoring cycle, in order to solve the above problems, this application proposes a corresponding solution. , see figure 2 ,Specifically:

[0054] Based on the structure of the first embodiment, before acquiring the channel state information of the WIFI signal in the room where the air conditioner is located, the current time is acquired, and the current time is determined to be the distance from the last execution of acquiring the channel state information of the WIFI signal in the room where the air conditioner is located. Whether the time of the step of checking has been separated by the preset action statistics time, if so, update the count value of the action counter to 1, obtain the channel state information of the WIFI signal in the ro...

Embodiment 3

[0056] Embodiment 3, in practical application scenarios, especially in summer, the user turns on the air conditioner for a long time, and the user sleep time during the day is much less than the sleep time at night, and the amplitude of the actions generated during sleep is much smaller than that generated during non-sleep. If you set the same detection intensity, it will either increase the number of computer calculations during the day and reduce the performance of the CPU, or increase the operating time of the air conditioner at night due to less detection frequency, which is not conducive to energy saving. In order to solve the above problems, this The application proposes corresponding solutions according to the user's living habits, please refer to image 3 ,Specifically:

[0057] If the current moment is within the preset first time period, execute the first preset motion statistics duration, the first sleep monitoring period, and the first sleep recognition determinati...

Abstract

The invention relates to a method for shutdown based on WIFI channel state detection, electronic equipment and a medium. The method comprises the steps that information among N subcarriers in channel state information of WIFI signals in a room where the air conditioner is located is obtained, a covariance value among the subcarriers is calculated according to the channel state information, whether the covariance value is larger than an action recognition threshold value or not is judged, if yes, the count value of an action counter is updated, and if not, the count value of the action counter is updated. The action counter is used for counting the action frequency generated by a user in a sleep monitoring period, when a count value in the action counter meets a sleep recognition judgment condition, the air conditioner is instructed to perform shutdown operation, and the sleep recognition judgment condition comprises a calculation threshold value of the action counter for judging that the user enters a sleep state. According to the scheme, when it is recognized that the user enters the sleep state, the air conditioner is indicated to conduct the shutdown operation, and therefore intelligent shutdown of the air conditioner is completed.

Description

technical field [0001] The present application relates to the technical field of air conditioners, and in particular, to a method for shutting down based on WIFI channel state detection. Background technique [0002] At present, household air conditioners are widely used, and most of the air conditioners use the remote control to enter the sleep mode to shut down the air conditioner. When users use it, they often do not have the habit of setting the air conditioner to shut down regularly, resulting in a large amount of electricity consumption by residents. After the user falls asleep, the pores are in a relaxed and open state, and it is easy to catch cold. Once the cold occurs, the body's resistance tends to decline, which is likely to endanger the user's health. [0003] How to realize intelligent shutdown according to the user's actual sleep state when the air conditioner is not set to shut down regularly. SUMMARY OF THE INVENTION [0004] In order to overcome the probl...
