Description
Technical Field
The invention relates to the field of electric appliance control, in particular to an indoor personnel detection method, an electric appliance control method, a controller, an indoor electric appliance and a storage medium for public places such as offices, office buildings and the like.
Background
Compared with the household air conditioner, the fan, the water dispenser and the like in the public building, the user personnel is complicated, and the problem of energy waste and potential safety hazard caused by forgetting to turn off the air conditioner fan, the water dispenser, the socket and the like is generally caused when people leave work or leave offices.
In order to solve the above problems, some solutions exist at present, for example, a method and a device for controlling an air conditioner to automatically turn off in patent 201410521222.8, a method, a device and an air conditioner for controlling an air conditioner to turn on and turn off in 201610497439.9, all of which use human body induction to solve the problem, but the human body induction sensor has high cost, large volume and high requirement on installation position, and cannot be installed on a temperature control panel such as a fan coil, so that practical popularization is difficult.
There is also patent 201210422114.6 light-operated energy-saving switch for central air conditioner, which uses a photosensitive relay and a fixed brightness variation threshold value to control the switch of fan of coil lamp in the indoor fan of central air conditioner, and its purpose is only to solve the problem of turning off the air conditioner at night or in dark condition without light in the room. Most of public places such as offices and office buildings can be kept on in daytime, when the lights are turned off when indoor personnel leave in daytime, no people exist in the room, but the indoor brightness is still high and is not lower than a threshold value, the air conditioner can not be turned off at the moment, and the condition of energy waste is caused; in addition, the background brightness of different rooms after the lamp is turned off in the daytime is different, and a fixed brightness threshold value cannot be set; meanwhile, the scheme has an obvious defect that: after the air conditioner is turned off due to dimming of light, the air conditioner is locked and cannot be turned on any more, even if indoor personnel have air conditioner requirements, the air conditioner can be turned on only by turning on the lamp to unlock the air conditioner, for example, the indoor personnel turn off the lamp at noon for rest or sleep in the room at night, so that the air conditioner cannot be used, and therefore, the air conditioner is not practical at all.
It can be seen from the above prior art that the unreasonable indoor personnel detection method or the high cost thereof finally affects the intelligent control effect of the electrical appliances such as the air conditioner.
In addition, the electric appliances such as the indoor fan coil temperature control panel in the central air-conditioning system are low in cost and small in size, are turned on and turned off through keys in physical contact at present, are not turned on and turned off through non-contact light or gestures, and risk of cross infection of viruses through the keys exists in daily use of fan coils installed in public places such as hospitals. For the problem, there is a scheme of adopting gesture control, and the existing non-contact gesture switches all adopt technologies such as infrared rays, camera image recognition, ultrasonic waves, microwave radars and the like, and are generally used for gesture recognition with complex functions, although the functions are strong, the system is often very complex and the cost is high. Indoor visible light is not utilized, and in the prior art, the indoor visible light is taken as an unstable interference source to avoid the visible light to the utmost extent.
In view of the above problems, it is urgently needed to find a more reasonable indoor personnel detection method for energy-saving management of indoor electrical appliances in public buildings, so as to solve the problem that people in public places forget to turn off electrical appliances such as air conditioners, fans, water dispensers, sockets and the like when leaving offices and after work, and to find a low-cost and simple non-contact power on/off technology so as to solve the problem of non-contact power on/off of electrical appliances in public buildings.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
It is noted that the terms "first," "second," and the like in the description of the present invention are used for descriptive purposes only and are not intended to indicate or imply relative importance or order. Further, in the description of the present invention, the meaning of "a plurality" means at least two unless otherwise specified. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Example 1
The embodiment provides an indoor personnel detection method, which comprises the following steps:
acquiring the brightness of the current environment acquired by the light sensing element in real time;
comparing the brightness of the current moment with the brightness of the previous moment;
and if the brightness at the current moment is lower than the brightness at the previous moment, the absolute value of the brightness difference exceeds a preset brightness difference threshold value, and the first preset duration is maintained, it is judged that the personnel leave the room.
In the indoor environment of the existing public building, the detection of whether indoor personnel leave is realized only by a control mode of a light-sensing switch or a circuit with the brightness lower than a fixed threshold value, the detection of whether indoor personnel leave cannot be accurately detected, and the indoor complex brightness environment cannot be adapted; the embodiment adopts the brightness difference threshold value, can be self-adaptive to indoor brightness backgrounds of different public buildings, not only can be used at night, but also can be used in the daytime, and whether indoor personnel leave can be reasonably judged, so that the indoor electrical appliance can be better turned off.
Example 2
The embodiment provides an indoor electrical appliance control method, which operates a light sense on/off mode, wherein the light sense on/off mode control process comprises the following steps:
s01: acquiring the brightness of the current environment acquired by the light sensing element in real time;
s02: comparing the brightness of the current moment with the brightness of the previous moment;
s03: and if the brightness at the current moment is lower than the brightness at the last moment, the absolute value delta K of the brightness difference exceeds a preset brightness difference threshold value delta Ks, and the first preset time duration is maintained, controlling the indoor electric appliance to be switched to the low-output power state and operate for a second preset time duration, and then closing or directly closing the indoor electric appliance.
It should be noted that the indoor electrical appliances include, but are not limited to, an air conditioner, a fan, a water dispenser, and a socket, and the control method of the indoor electrical appliances provided by this embodiment can realize the control of a single indoor electrical appliance, and can also realize the simultaneous control of multiple indoor electrical appliances.
The scene of also turning on light daytime in public places such as many offices, after closing light daytime, luminance can reduce, but luminance is still higher, and present only can realize closing indoor electrical apparatus after turning off light evening through judging whether luminance is less than the mode of threshold value, can't realize closing indoor electrical apparatus after turning off light daytime. In view of this situation, the present embodiment innovatively provides that the on/off control of the indoor electrical appliances is realized in a brightness difference manner, and if the brightness at the current time is lower than the brightness at the previous time, the absolute value of the brightness difference exceeds a preset brightness difference threshold, and the first preset duration is maintained, all the indoor electrical appliances can be controlled to be directly turned off. Of course, for indoor electric appliances such as air conditioners, fans and the like, the indoor electric appliances can be selectively controlled to be switched to a low-output-power state to operate for a second preset time period and then be switched off. This embodiment has realized no matter evening or daytime, all can realize the intelligence and close indoor electrical apparatus under the condition of forgetting to close indoor electrical apparatus.
In consideration of the fact that people often leave temporarily in real life, if the air conditioner and the fan are directly turned off, the problem that the indoor electric appliances are frequently turned on and off is caused, the service life of the indoor electric appliances is shortened, and energy waste is increased due to frequent turning on and off. Therefore, for such indoor electrical appliances, it is preferable to solve the problem by delaying shutdown, in the delaying process, the indoor electrical appliances are switched to operate in the low output power state, and during the indoor electrical appliances are switched to operate in the low output power state, if it is detected that the brightness at the current moment is higher than the brightness at the last moment and the absolute value of the brightness difference exceeds the preset brightness difference threshold, the instruction is given that the person returns, and at this time, the indoor electrical appliances are controlled to return to the state before being switched to the low output power state, so that the problem of frequent startup and shutdown caused by temporary departure of the person is effectively avoided, and energy is saved. For indoor electric appliances such as sockets and water dispensers, if the brightness at the current moment is detected to be higher than the brightness at the previous moment after the indoor electric appliances are closed, and the absolute value of the brightness difference exceeds a preset brightness difference threshold value, the indoor electric appliances are controlled to be restored to the state before the indoor electric appliances are closed. It should be noted that, for the socket, considering that it is not suitable to be closed in the middle of the day in some scenes, such as an office with a person in the middle of the day, the time at which the socket can be closed can be set in advance, such as after 5 or 6 pm.
Wherein the low output power state comprises: if the indoor electric appliance is an air conditioner, the set temperature of the air conditioner is increased in a refrigeration mode; for the heating mode, the air conditioner set temperature is reduced; or reducing the air speed of the air conditioner; or the air speed of the air conditioner is reduced while the temperature is correspondingly adjusted in the cooling mode/heating mode; in specific implementation, one mode is selected in the low output power state according to actual needs;
if the indoor electric appliance is a fan, the fan speed is reduced.
In addition, for scenes such as offices, people may close lights and curtains for noon break at noon, and in the prior art, in a mode that indoor electric appliances such as an air conditioner are closed when the brightness is lower than a threshold value, the indoor electric appliances are closed and locked, and cannot be started any more, so that the actual use experience of the indoor electric appliances such as the air conditioner is seriously influenced. In this embodiment, the priority of the key operation mode is set to be higher than that of the light-sensing on/off mode, and if the key operation instruction is received, the key operation instruction is preferentially executed, and the light-sensing on/off mode is restored to the initial state when the key is turned on, or the light-sensing on/off mode is directly exited. Therefore, even if the indoor electric appliances such as an air conditioner can be turned on through key operation in the shutdown state of the light sensation on-off mode, the intelligent and humanized effects are achieved.
It should be noted that the brightness can be represented by the magnitude of the electric signal induced by the light sensing element, and the preset brightness difference threshold is set according to actual needs. The first preset time and the second preset time are selected according to actual needs, and for example, the first preset time can be selected to be 2 minutes, 5 minutes, 10 minutes and the like; the second preset time period may be selected to be 10 minutes, 20 minutes, 30 minutes, etc. As shown in fig. 1, an embodiment is shown in which the first predetermined period of time is 5 minutes and the second predetermined period of time is 10 minutes.
Example 3
The embodiment of the invention provides an indoor electric appliance control method, which is based on the embodiment 2 and further comprises the following steps:
if the brightness of the current environment is detected to be changed from bright to dark to bright for N times continuously within a third preset time, turning on or turning off the indoor electric appliance; wherein the third preset time is less than the first preset time, and N is more than or equal to 2.
Specifically, when the indoor electric appliance is in a starting state, if the brightness of the current environment is detected to be continuously changed from bright to dark and then to bright for N times within a third preset time period, the indoor electric appliance is turned off; when the indoor electric appliance is in a closed state, if the brightness of the current environment is detected to be changed from bright to dark to bright for N times continuously within a third preset time, the indoor electric appliance is turned on.
The non-contact on-off control is realized by judging whether the number of times of detecting that the brightness of the current environment is continuously changed from bright to dark to bright within the preset time reaches the preset number of times. The setting can be realized by shaking the light sensing element back and forth by hands, a new gesture control mode is provided, and the control can be realized by controlling the light to be turned on and off for many times. The brightness difference control can be realized by sharing one light sensing element with the brightness difference control in the embodiment 2, a signal source is not needed, the structure is simple, and the cost is low. The method does not cancel the original physical key operation mode, and the original on-off key can be used simultaneously, only one non-contact on-off function is added or redundant, so that the method is most stable and reliable. The indoor electric appliances are switched on and off by non-contact gestures, so that the service life of the original keys can be prolonged, and the risk of virus cross infection caused by manual operation can be greatly reduced for the indoor electric appliances in public places such as hospitals and the like.
Taking an indoor electric appliance as an air conditioner as an example, for public places with large spaces, such as a hall or a large conference room, the problem of more air conditioner switches or scattered switches exists, all the air conditioners can be turned off or on simultaneously in a mode of continuously turning on and off the lamps for multiple times, and the operation is simple and convenient. For a single air conditioner, besides the key on/off, the on/off can also be realized by shaking the light sensing element back and forth by hand.
The third preset time period may be set according to actual conditions, and is generally 0.1 to 3 seconds. In addition, the value of N is greater than or equal to 2, and for convenience of operation, N is preferably 2 or 3.
