Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flow chart of an electrical apparatus control method according to an embodiment of the present application, and as shown in fig. 1, the electrical apparatus control method includes the following steps:
and step S101, acquiring a radar detection signal.
The present application will be described below with reference to an air conditioner as an example.
In the related art, the air conditioning equipment which is controlled to operate by a human body is detected based on the infrared sensor, and is easily influenced by interference of other infrared signals and other heat sources during infrared detection.
For example, an active emission type infrared sensor determines whether a human body approaches through the cooperation of an infrared emission head and a receiving head, and when the human body enters a detection area, an infrared signal emitted by the infrared emission head is emitted to the infrared receiving head by the human body, so that the detection of the human body is realized. However, in practical applications, the active emission type infrared sensor is easily interfered by other infrared signals, for example, in a home application scenario, there are many electrical apparatuses, and accordingly, there are also many infrared remote controllers matching with various electrical apparatuses, and when performing infrared remote control by using various other infrared remote controllers, the active emission type infrared sensor of the air conditioner may generate erroneous judgment.
The passive reception type infrared sensor detects a human body by using the heat radiated from the human body, but has a problem that erroneous judgment is easily generated in actual use when the temperature of the human body is close to the ambient temperature or the detection is affected by other heat sources. For example, in a household application scene, a heat source can be formed by remotely starting the intelligent hot water kettle to boil water, a heat source can also be formed by remotely starting the intelligent electric rice cooker, and the like, so that misjudgment can be caused by the infrared detection of the air conditioner.
It can be understood that the radar detection signal can avoid the interference of other infrared signals and the influence of other heat sources, and various problems caused by the adoption of the infrared sensor are overcome.
In specific application, a radar detection device can be configured in the air conditioner to obtain a radar detection signal, a transmitting antenna and a receiving antenna are configured in the radar detection device, the transmitting antenna continuously transmits electromagnetic wave signals to the space, the electromagnetic wave signals return to the receiving antenna after being reflected by a measured object, and the size, the shape and the like of the object can be detected by utilizing the radar detection signal. When the object to be measured moves relatively, the frequency difference is generated between the frequency of the echo and the frequency of the emitted electromagnetic wave, and the moving speed of the object to be measured relative to the radar can be measured by calculating the frequency difference. In practical application, the motion state and the direction of the human body can be accurately calculated through multiple transmitting antennas and multiple receiving antennas.
In one embodiment, the radar detection signal is a millimeter wave signal.
It can be understood that the millimeter wave radar has the characteristics of high resolution and the like, and the millimeter wave radar can be used for accurately calculating the motion state, the measurement length and width and the orientation information of a human body, so that the detection is more accurate. It should be noted that, the radar detection signal described above is a millimeter wave signal, and is for the purpose of illustration in this application. The method is not limited by the application, and the method can be selected according to actual conditions, for example, in order to realize high-precision detection, a laser radar signal can be selected.
And step S102, analyzing the radar detection signal to determine whether a human body exists.
In one embodiment, the analyzing the radar detection signal includes:
judging whether a moving object exists or not according to the radar detection signal;
if the moving object exists, analyzing the moving object according to first preset data to determine whether the moving object is a human body.
In the foregoing embodiment, the first preset data may be human body size data. Such as height data, width data, etc. of the human body. It should be noted that the first preset data is not limited to the size data of the human body, and may be contour shape data of the human body, and the like.
In practical application, the first preset data may be given by an air conditioner manufacturer, or may be set by a user according to a situation of the user. For example, the user sets height range data and width range data suitable for the family of the user according to the height condition and the width condition of the family, and accurate detection and identification are further achieved.
It can be understood that, by analyzing the radar detection signal, it may be analyzed whether there is a moving object, a size of the moving object, and the like, and when the moving object is detected, it may be determined whether the moving object is a person or another object according to a preset size of the moving object, and the other object may be a pet at home, such as a cat or a dog, or may be a moving electrical device, such as an automatic floor sweeping robot.
The above embodiment scheme is further explained by specific application scenarios.
In a household air conditioner application scene, first preset data set in an air conditioner by a user are height and width of a human body. And under the condition that a moving object enters the detection area, the air conditioner detects the occurrence of the moving object according to the radar detection signal, further identifies the moving object to obtain the height and the width of the target object, and then compares the height and the width with first preset data to judge whether the moving object is a human body or other objects. For example, the situation that a pet is at home, for example, an automatic floor sweeping robot is at home, can be judged that the moving object is not a human body by comparing with the first preset data, so that misjudgment that the moving object is a human body can be avoided.
In the above embodiment, the moving object is determined to determine whether the moving object is a human body, and in a real life scene, the user does not always move, and in many cases, the user state may be a state in which the user does not move for a long time, for example, a rest state.
In one scenario, a person is present at home, but the user is still asleep and not moving, and the presence of the user needs to be identified.
In another embodiment, the analyzing the radar detection signal further includes:
if the moving object does not exist, judging whether a suspicious object which accords with the first preset data exists or not according to the first preset data;
if the suspicious object exists, analyzing the suspicious object according to second preset data to determine whether the suspicious object is a human body.
Through the scheme of the embodiment, the user can keep the air conditioner in the recognition state of detecting the human body under the condition of not moving.
In one embodiment, the second preset data may be human motion data. For example, the actions of the head, the hands, the legs, and the like, take the millimeter wave radar as an example, the millimeter wave radar has high resolution, and can recognize the detailed actions of the user.
Similarly, in practical applications, the second preset data may be provided by an air conditioner manufacturer, or may be set by a user according to the situation of the user.
The above embodiment scheme is further explained by specific application scenarios.
In a household air conditioner application scene, when a user sleeps, the air conditioner does not detect the movement of a human body, the air conditioner does not judge that no human body exists at the moment, but judges whether a suspicious object which accords with the first preset data exists according to the first preset data, and if yes, the air conditioner needs to confirm whether the suspicious object is a human body. At this moment, the air conditioner detects and identifies the object according to second preset data, for example, the detection time can be set, the detail action of the suspicious object is detected within the detection time, when one detail action appears or a plurality of details appear simultaneously, the appeared detail action is compared with the second preset data, if the detail action can be matched in the second preset data, the suspicious object is judged to be a human body, and the air conditioner is still in a state of detecting the human body.
And S103, controlling the electrical equipment to operate according to the analysis result.
In an embodiment, the controlling the operation of the electrical equipment according to the analysis result includes:
and if the human body is analyzed to exist, controlling the electrical equipment to operate according to a preset mode.
In the above embodiment, when a human body is analyzed, it is described that the air conditioner needs to be controlled to switch the operation mode, and for a preset mode, in a specific application, the preset mode may be an automatic mode, a cooling mode, a heating mode, and the like, and the preset mode may be set by a user according to a weather condition, for example, the preset mode is set to the heating mode in the case of cold weather, and the preset mode is set to the cooling mode in the case of hot weather.
In an embodiment, the controlling the operation of the electrical equipment according to the analysis result includes:
and if the human body does not exist, controlling the electrical equipment to operate in a standby mode.
It can be understood that if no human body exists, the standby operation of the electrical equipment is controlled, and the energy-saving operation of the air conditioner can be realized.
In a specific application, if the air conditioner radar cannot detect a moving object and cannot detect a suspicious object which accords with the first preset data, the air conditioner radar can be determined that the human body leaves a detected area, or the detected area does not have the human body, accordingly, the air conditioner is controlled to enter a standby state, and the air conditioner radar keeps a continuous detection state.
In another embodiment, the controlling the operation of the electrical equipment according to the analysis result further includes:
and judging whether the standby operation time reaches the preset standby time or not, and controlling the electrical equipment to be shut down when the standby operation time reaches the preset standby time.
In the above embodiment, the preset standby time may be specifically set according to the needs of the user. For example, the number of people getting in and out of a home is large, and the preset standby time can be set to be a little longer.
Fig. 2 is a schematic flow chart of an electrical apparatus control method according to another embodiment of the present application, and as shown in fig. 2, the electrical apparatus control method includes the following steps:
step S201, a radar detection signal is acquired, and step S202 is executed.
Step S202, judging whether a moving object exists according to the radar detection signal; if the moving object exists, executing step S203; if not, go to step S204.
Step S203, analyzing the moving object according to first preset data, determining whether the moving object is a human body, and if so, executing step S205; if not, go to step S206.
Step S204, judging whether a suspicious object conforming to the first preset data exists or not according to the first preset data; if yes, go to step S207, and if not, go to step S206.
And S205, controlling the electrical equipment to operate according to a preset mode, and repeatedly executing the step S201.
And S206, controlling the electric equipment to operate in a standby mode, and repeatedly executing the step S201.
Step S207, analyzing the suspicious object according to second preset data to determine whether the suspicious object is a human body, if yes, performing step S205, and if not, performing step S206.
It can be understood that, the above embodiment is a specific application embodiment of the present application, and a specific implementation of the control method of the electrical equipment of the present application can be completely and comprehensively obtained from the flowchart of the scheme in fig. 2, and human bodies are respectively identified for a moving object and an immobile object according to the specific situation of whether the object moves, wherein when identifying the moving object, whether the moving object is a human body or another moving object can be identified; when identifying an immobile object, determining whether a suspicious object exists, and then identifying whether the suspicious object is a human body.
In terms of the control and operation of the electrical equipment, various conditions for triggering the control of the electrical equipment to operate in a preset mode can be obtained through the scheme flow chart of fig. 2.
For example,
detecting a moving object, and if the moving object accords with first preset data, controlling the electrical equipment to operate according to a preset mode; or,
and if the moving object is not detected, if the suspicious object is judged to exist according to the first preset data and the suspicious object is judged to be a human body according to the second preset data, controlling the electrical equipment to operate according to a preset mode.
Likewise, various conditions for triggering the standby operation of the control electrical device can also be obtained through the scheme flow chart of fig. 2.
For example,
detecting a moving object, and controlling the electric equipment to operate in a standby mode if the moving object does not accord with the first preset number; or,
if the moving object is not detected and the existence of the suspicious object is not judged according to the first preset data, controlling the electric equipment to operate in a standby mode; in the alternative to this, either,
and if the moving object is not detected, although the suspicious object is judged to exist according to the first preset data, the suspicious object is judged not to be a human body according to the second preset data, and the electric equipment is controlled to operate in a standby mode.
The scheme of the flow chart in the figure 2 can realize comprehensive judgment of human body detection conditions, corresponding air conditioner actions are executed according to corresponding judgment, misjudgment conditions can be effectively reduced, the operation of the electrical equipment controlled by identifying the human body through radar detection is more accurate, and the use experience of a user can be improved.
