Background

Present traditional air conditioner when user sleep state uses, needs set for the operating parameter of air conditioner before sleeping, adjusts indoor air, and the air supply parameter of setting for before sleeping often only satisfies the user physiological state before sleeping, after the user sleeps, continues to use this air supply parameter, and the condition of supplying air that appears easily mismatches with user physiological demand lets the user appear uncomfortable when sleeping, the condition of waking up or being waken up cold even appears.

Examples

As shown in fig. 1, the present embodiment provides an air conditioning control system, including:

the first acquisition module is used for acquiring the indoor environment temperature;

the second acquisition module is used for acquiring the infrared thermal image of the person in the sleeping state;

the analysis module is used for processing the infrared thermal image and judging the cold and hot degree of the human body in a sleeping state by combining the indoor environment temperature;

and the control module is used for controlling the operation of the air conditioner according to the cold and hot degree judgment result.

In this embodiment, the first acquisition module is a temperature sensor. The temperature sensor can sense the indoor environment temperature and convert the indoor environment temperature into a usable output signal which is sent to the analysis module. The temperature sensors can be classified into a contact type and a non-contact type according to the measurement mode, and classified into a thermal resistor and a thermocouple according to the characteristics of sensor materials and electronic elements.

The detection part of the contact temperature sensor is in good contact with a measured object, and is also called as a thermometer. The thermometer reaches thermal equilibrium through conduction or convection, so that the indication value of the thermometer can directly represent the temperature of the measured object. Generally, the measurement precision is higher. The thermometer can also measure the temperature distribution inside the object within a certain temperature measuring range. However, a large measurement error occurs in a moving body, a small target, or an object having a small heat capacity, and commonly used thermometers include a bimetal thermometer, a glass liquid thermometer, a pressure type thermometer, a resistance thermometer, a thermistor, a thermocouple, and the like. Such as low temperature gas thermometers, vapor pressure thermometers, acoustic thermometers, paramagnetic salt thermometers, quantum thermometers, low temperature thermal resistors, low temperature thermocouples, and the like. The low temperature thermometer requires the temperature sensing element to be small in size, high in accuracy, good in reproducibility and stability. A carburized glass thermal resistor formed by carburizing and sintering porous high silica glass is a temperature sensing element of a low-temperature thermometer and can be used for measuring the temperature within the range of 1.6-300K.

In this embodiment, the second acquisition module is an infrared temperature camera, that is, an infrared temperature measurement camera, and a human body temperature measurement type infrared thermal imaging camera, and the detector is adopted to realize accurate and rapid temperature measurement and over-temperature alarm through technologies such as human body temperature compensation and temperature automatic correction, so as to ensure that the system works stably for a long time without missing detection and false alarm. The human body temperature monitoring camera can effectively replace manual measurement, manual inspection is avoided, the inspection efficiency is low and incomplete, epidemic situations caused by omission and uncertainty, disease deterioration, diffusion and the like are avoided.

In this embodiment, the air conditioning control system further includes a preprocessing module, where the preprocessing module is configured to preprocess the infrared thermal image before the analysis module, and includes: and enhancing the infrared thermal image, generating wavelet denoising threshold selection, performing global image denoising, and performing high-pass filtering according to the characteristic that the human body temperature is higher than the environmental temperature. The high-pass filtering is a filtering method, and the rule is that high-frequency signals can normally pass through, and low-frequency signals lower than a set critical value are blocked and weakened. But the magnitude of the blocking and attenuation will vary depending on the frequency and filtering procedure (purpose). It is sometimes also called low frequency removal filtering. High-pass filtering is the opposite of low-pass filtering.

In this embodiment, when determining the cooling and heating degree, the infrared thermal image is processed to obtain the exposed portion of the body, and the cooling and heating degree of the human body in the sleep state is determined by combining the skin temperature of the exposed portion and the indoor environment temperature.

Specifically, handle infrared thermal image, acquire the naked position of health, include: carrying out boundary segmentation on the human body part on the infrared thermal image, determining the position of a limb area, and identifying the area exposed out of the bedding; the limb areas include the head and face, torso, upper limbs, and lower limbs.

In this embodiment, when the infrared thermal image is subjected to human body part segmentation, a targeted local threshold human body binarization algorithm is performed according to the distribution characteristics of human body and background temperature in the thermal infrared image by using a human body thermal infrared image splicing and part segmentation method disclosed in photoelectric engineering, 2019, volume 46, and phase 9, and accurate splicing of upper and lower half-body images is realized based on an overlapping region matching algorithm of a binary template and a gray template; the method for calculating key points based on human body contour features realizes human body part division.

Specifically, in one embodiment, the determining the degree of warmth and coldness of the human body includes: if the indoor environment temperature is lower than the skin temperature of the exposed part and the difference value between the indoor environment temperature and the skin temperature of the exposed part is larger than a first threshold range, judging that the cold and hot degree is relatively cold; if the indoor ambient temperature is 23 degrees and the skin temperature is 34.5 degrees, the difference between the two is 11.5 degrees and is greater than 10.5 degrees of the first threshold range (7.5-10.5), then the human body perception cold and hot degree is judged to be cold.

When the indoor environment temperature is higher than the exposed part temperature, the cold and hot degree is judged to be bias heat.

In one embodiment, the determining the degree of warmth of the human body further includes: the indoor environment temperature is lower than the skin temperature of the exposed part, and the difference value between the indoor environment temperature and the skin temperature of the exposed part is within a first threshold range, so that the cold and hot degree is judged to be proper; for example, the indoor ambient temperature is 26 degrees, the skin temperature is 34.5 degrees, and the difference between the indoor ambient temperature and the skin temperature is 8.5 degrees, which is within the first threshold range (7.5-10.5), so that the human body can perceive a proper cold and hot degree. The indoor environment temperature is lower than the skin temperature of the exposed part, and the difference value between the indoor environment temperature and the skin temperature of the exposed part is smaller than a first threshold range, and then the cold and hot degree is judged to be relatively cold; if the indoor environment temperature is 30 degrees, the skin temperature is 34.5 degrees, and the difference between the indoor environment temperature and the skin temperature is 4.5 degrees and less than 7.5 degrees, the human body perception cold and hot degree is judged to be partial heat.

In one embodiment, if the cold and hot degree is judged to be cold, the control module controls the operation parameters of the air conditioner to increase the indoor environment temperature; if the cold and hot degree is judged to be appropriate, the control module controls the air conditioner operation parameters to be kept unchanged; if the cold and hot degree is judged to be partial heat, the control module controls the air conditioner operation parameters to reduce the indoor environment temperature.

As shown in fig. 2, in the present embodiment, the method for controlling air conditioning by using the air conditioning control system includes:

the method comprises the following steps of collecting indoor environment temperature by using a temperature sensor, and sending temperature data to an analysis module; the method comprises the following steps of collecting an infrared thermal image of a person in a sleeping state by using an infrared temperature measurement camera, and sending the image to an analysis module; processing the infrared thermal image, and judging the cold and hot degree of the human body in a sleeping state by combining the indoor environment temperature; and controlling the air conditioner to operate according to the cold and hot degree judgment result.

In summary, the air conditioner control system and the control method according to the embodiments of the present invention collect the body state and the temperature condition of the human body in the sleep stage through the infrared temperature camera, and relate to whether some of the body is exposed outside the blanket or not, the skin temperature of the exposed part, and the like, and transmit the body state and the temperature condition to the analysis module, and the analysis module obtains the temperature of the exposed part by analyzing the image recognition in combination with the working conditions in winter and summer and the current indoor temperature condition, determines the cold and hot degree of the human body in sleep, and adjusts the indoor temperature. Based on the analysis output of the intelligent module, the control module automatically controls the air outlet speed, the temperature, the start and stop of the air conditioner module, so that the sleeping personnel are in a comfortable environment, and the sleeping quality is ensured.

When being applied to the sleep scene:

the personnel do not have the exposed part except the head, and the cold and hot degree of the personnel is judged by combining the indoor temperature and the head and face temperature of the personnel, so that the air conditioner operation is timely adjusted.

When the rest parts of the body of a person are exposed and the skin temperature of the exposed part is in a comfortable range, the heat sensation of the person is moderate, the current environment can be kept unchanged, and the operation of an air conditioner is not required to be adjusted; if the skin temperature of the exposed part is higher or lower than the comfortable interval, the sleeping person may feel hot or cold, and the air conditioner is adjusted to operate correspondingly to reach the appropriate temperature environment.

When people are hot during sleeping, the people generally kick and turn over the bedding, so that part of limbs are exposed outside, the skin temperature condition of the exposed part is determined through image recognition, and the air supply state of the air conditioner is adjusted; when people are cold, the blanket is generally covered completely, and at the moment, the cold and hot degrees of the people are judged by combining image recognition and the head and face exposed temperature, so that the adjustment of air supply parameters is determined; for the limb exposure caused by the non-bias-heat reason of the personnel (for example, the blanket can not be fully covered due to the actions of turning over and the like), the corresponding judgment can be made according to the limb identification and the temperature condition of the exposed part, if the temperature of the exposed part is low and the personnel are cold, the parameters such as air supply temperature and the like can be improved, and the catching of cold is avoided.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and it should be understood by those skilled in the art that various modifications and variations can be made without inventive efforts based on the technical solutions disclosed in the present invention.
