s40 b: when the temperature of the static heat source is greater than a preset temperature threshold value, outputting a voice alarm prompt; or displaying an alarm prompt on a display unit of the air conditioner; or sending an alarm prompt to a terminal or a background server connected with the air conditioner.
In this embodiment, the control method based on the air conditioner mainly detects an indoor stationary heat source through a pyroelectric infrared detection device, the pyroelectric infrared detection device includes a pyroelectric infrared sensor with a fresnel lens and a stepping motor, the stepping motor drives the pyroelectric infrared sensor to move to detect the indoor stationary heat source, so that a relative motion trend is formed between the pyroelectric infrared sensor and the stationary heat source, so that the fresnel lens can continuously and alternately enter a high-sensitivity region from a 'dead zone' to generate an electric signal, the electric signal is transmitted to a single-point pyroelectric infrared sensor, the pyroelectric infrared sensor receives the electric signals with different intensities to generate a series of pulse waves, the pulse electric waves are processed by a peripheral circuit (noise removal and high-frequency clutter removal), and then are converted into digital pulse signals to be fed back to a processor of the air conditioner, the processor judges the detection angle of the pyroelectric infrared detection device when receiving the pulse signal, calculates the relative position relation of a static heat source relative to the pyroelectric infrared detection device by utilizing an algorithm after acquiring the pulse signal in a period, and intelligently adjusts the set temperature and the air outlet parameter of the air conditioner by combining the indoor and outdoor temperature, and the specific steps are as follows:
after receiving a starting instruction, the air conditioner enters a refrigerating running state or a heating running state according to the starting instruction, and cold or heat is conveyed indoors, wherein the starting instruction can be generated by an air conditioner remote controller, an on-off key of an air conditioner interaction interface and user operation on a terminal, and can also be synchronously generated along with an entrance guard signal when an entrance guard system consisting of a pyroelectric infrared sensor detects that a user enters a room. After the air conditioner is started, controlling a pyroelectric infrared detection device arranged on the air conditioner to execute initialization operation, wherein the initialization operation is executed once every preset time after the air conditioner is started so as to ensure the accuracy of detection data in each detection period.
After the pyroelectric infrared detection device completes initialization, an initialization completion instruction is fed back to a processor of the air conditioner, so that the processor controls the pyroelectric infrared detection device to detect an indoor static heat source within a preset angle range, the pyroelectric infrared detection device is usually installed near an air outlet of an indoor unit of the air conditioner, most of indoor areas can be brought into a scanning area, the preset angle range is that the pyroelectric infrared detection device is initialized and then 90 degrees are respectively arranged at the left or right, therefore, the preset rotation angle range is 0-180 degrees, and the preset rotation angle range can be optimized to be 0-160 degrees according to actual needs.
In the detection process of the pyroelectric infrared detection device, the pyroelectric infrared detection device rotates leftwards by a quarter angle of the preset rotation angle from an initialized position as a starting point, then rotates rightwards by a half angle of the preset rotation angle, and finally rotates leftwards by a quarter angle of the preset rotation angle to complete a detection period, in the detection period, when the pyroelectric infrared detector detects a static heat source, namely the pyroelectric infrared detector moves relative to the static heat source, infrared rays radiated by the static heat source generate suddenly strong and weak electric signals in a high sensitive area and are transmitted to the pyroelectric infrared sensor, and due to different intensities of received electric signals, a string of pulse waves are processed by a peripheral circuit and then converted into digital pulse signals to be fed back to a processor of an air conditioner, and the processor can acquire the deflection angle of the pyroelectric infrared detection device relative to the preset initial position when receiving each pulse signal, and then calculating the relative position information of the static heat source through a plurality of deflection angles in the period.
After the relative position information of the static heat source is obtained, the air conditioner can be intelligently adjusted according to the type of the static heat source, for example, when the static heat source is a human body, the running state of the air conditioner can be intelligently judged by combining indoor and outdoor temperature and/or humidity, and then the air conditioner is automatically controlled to adjust the set temperature and/or air outlet parameters, for example, the air supply mode of the air conditioner is adjusted to be a following air supply mode, the air conditioner is controlled to supply air to the area where the human body is located according to the relative position information, or the air supply mode is avoided, the air conditioner is controlled to supply air to other areas according to the relative position information, and the air outlet quantity is adjusted to be small.
When the static heat source is a non-human body, further judging to obtain the real-time temperature of the static heat source, and when the temperature value of the static heat source is greater than a preset temperature threshold value, if the temperature value is greater than 80 ℃, deducing that a fire risk exists, and further outputting an alarm prompt, for example, outputting a voice alarm prompt when a user is detected to be far away from the air conditioner according to the relative position information, or outputting a language alarm prompt with overhigh temperature when the user is detected to be far away from the air conditioner through a proximity sensor or a camera, and also displaying the alarm prompt with overhigh temperature on a display unit of the air conditioner when the user is detected to be within a visual range of the air conditioner according to the proximity sensor or the camera, wherein the alarm prompt can be a flashing prompt or a text prompt. The display unit of the air conditioner is also used for displaying water temperature parameters, air quality parameters, current indoor and outdoor temperature parameters, time parameters and the like. In addition, when the air conditioner is detected to be capable of being connected to a terminal device, such as a mobile phone, a PAD and a tablet, an alarm prompt with overhigh temperature is sent to the terminal device, or when the air conditioner is detected to be capable of being connected to a background server of a supplier, the alarm prompt can also be sent to the background server, so that the life and property safety of a user is guaranteed.
