Description
Technical Field
The invention belongs to the field of air conditioning system control, and particularly provides an air conditioning system and a human body temperature detection method and a human body temperature control method thereof.
Background
With the advancement of technology, air conditioning systems are also more and more intelligent. Some air conditioning systems have been able to adjust their operating parameters, such as increasing or decreasing cooling or heating power, based on the relationship between the ambient temperature and the human body temperature in the room.
The air conditioning systems in the prior art generally adopt a non-contact mode to acquire the body temperature of indoor people. Specifically, an infrared thermal imaging sensor is arranged on the air conditioning system, and the body temperature of indoor personnel is obtained through the infrared thermal imaging sensor. The infrared thermal imaging sensor utilizes an infrared detector and an optical imaging objective lens to receive an infrared radiation energy distribution pattern of a detected target and reflect the infrared radiation energy distribution pattern to a photosensitive element of the infrared detector, so that an infrared thermal image is obtained, and the thermal image corresponds to a thermal distribution field on the surface of an object. Traditionally, thermal imagers have been used to convert the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured.
Because the air conditioning system does not need to be seen by people when detecting the temperature of the human body, some air conditioning systems only acquire the infrared radiation energy of the human body through an infrared detector, and then judge the temperature of the human body according to the intensity of the infrared radiation energy.
However, the infrared detector alone or the infrared thermal imaging sensor as a whole will drift, and the drift will be more and more serious with time, so that the air conditioning system cannot accurately detect the body temperature of indoor personnel, and further cannot reasonably control the operation parameters of the controller, and the user experience is poor. Here, drift refers to a phenomenon in which the sensor output amount changes with time while the sensor input amount is constant.
Accordingly, there is a need in the art for a new air conditioning system and a human body temperature detection method and control method thereof to solve the above problems.

fig. 2 is a flowchart illustrating a portion of the steps of the control method of the air conditioning system according to the present invention.
Detailed Description
It should be understood by those skilled in the art that the embodiments of the present invention are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, the air conditioning system of the present invention may be a household air conditioning system or a commercial air conditioning system, and those skilled in the art may make modifications as needed to suit a particular application, and the modified embodiments will still fall within the scope of the present invention.
Although not shown in the drawings, the air conditioning system of the present invention includes a thermostat, an infrared detection module, and a controller, wherein the controller is connected to the thermostat and the infrared detection module, respectively. The thermostat is capable of producing a constant temperature, in other words, the thermostat of the invention exhibits a constant temperature value when measured. Preferably, the thermostat comprises an electric heating element (e.g. a heating wire), further preferably the thermostat further comprises a temperature sensor for detecting the temperature of its surface, so that the combination of the electric heating element and the temperature sensor enables the temperature of the thermostat to be a constant value. Illustratively, the thermostat includes an electrical heating element, a temperature sensor, a switch, and a microcontroller. The output temperature of the thermostat is set through the microcontroller, when the thermostat works, the microcontroller enables the switch to be switched on, the electric heating element is powered on to start heating, the temperature sensor can detect the temperature generated by the electric heating element in real time in the process, and the detection result is sent to the microcontroller. When the temperature sensor detects that the temperature of the electric heating element reaches the set temperature, the microcontroller switches the switch to the off state; when the temperature sensor detects that the temperature of the electric heating element is below the set temperature, the microcontroller continues to switch the switch to the on state again.
Furthermore, the infrared detection module can be used for detecting infrared data sent by the thermostat and detecting human body infrared data of indoor personnel. Because the temperature of the thermostat is a constant value, the infrared data sent by the thermostat is also constant data, and based on the constant data, the constant and unchangeable temperature generated by the thermostat is defined as reference temperature, and the infrared data of the thermostat detected by the infrared detection module is defined as reference infrared data.
In addition, those skilled in the art may also desire to configure the thermostat to output components of any temperature by adjusting the settings of the microcontroller.
As shown in fig. 1, the human body temperature detection method for an air conditioning system of the present invention mainly includes:
step S101, acquiring a reference temperature of a thermostat;
step S102, enabling the infrared detection module to detect the thermostat to obtain reference infrared data;
step S103, enabling the infrared detection module to detect a human body to obtain human body infrared data;
step S104, acquiring an infrared data difference value between the human body infrared data and the reference infrared data;
step S105, acquiring a temperature difference value between the body temperature of the human body and the reference temperature of the thermostat according to the infrared data difference value;
and S106, acquiring the body temperature of the human body according to the temperature difference and the reference temperature.
Step S101 is an optional step, that is, when the human body temperature detection method of the present invention is used, step S101 may be executed or not executed. And, while not performing step S101, the temperature generated by the thermostat is preset by the microcontroller, remains unchanged, and the temperature value is stored in the controller or a memory module communicatively connected to the controller.
Specifically, in step S101, the controller first operates the thermostat for a preset time period so as to bring the thermostat to a preset temperature. And then sending information to a controller through a microcontroller, wherein the temperature is the reference temperature. In the preferred embodiment of the present invention, the reference temperature is 25 ℃, and those skilled in the art can set the reference temperature to any other feasible temperature, such as 0 ℃, 15 ℃, 30 ℃ and the like, as required.
Specifically, in step S102, the controller causes the infrared detection module to detect the thermostat and thus obtain the current infrared data of the thermostat. The infrared data is the reference infrared data.
Specifically, in step S103, the controller causes the infrared detection module to detect a person in the room and thus obtain human body infrared data of the human body. When a plurality of people exist indoors, the human body infrared data takes the highest value, the lowest value or the average value of the plurality of people. .
Specifically, in step S104, the human body infrared data is subtracted from the reference infrared data to obtain the current infrared data difference
Specifically, in step S105, an alignment list of infrared data difference values and temperature difference values is obtained, and then the obtained infrared data difference values are substituted into the alignment list and thus the temperature difference values are obtained. It should be noted that the comparison list is stored in advance in the controller or a memory communicatively connected to the controller, and each infrared data difference corresponds to a temperature difference in the comparison list. For example, the infrared data difference values include a1, a2, A3, a4, and a5 … …, and the temperature difference values include B1, B2, B3, B4, and B5 … …. The correspondence between the infrared data difference and the temperature difference in the comparison list is B1 corresponding to A1, B1 corresponding to A1, B2 corresponding to A2, B3 corresponding to A3, B4 corresponding to A4 and B5 … … corresponding to A5. Wherein A represents infrared data and B represents temperature.
Specifically, in step S106, the controller sums the reference temperature of the thermostat and the temperature difference value acquired in step S105 to obtain the current body temperature of the human body.
Based on the above description, those skilled in the art can understand that, since the comparison relationship between the infrared data difference and the temperature difference is constant, the present invention obtains the infrared data difference between the human body and the thermostat, then obtains the temperature difference between the human body and the thermostat according to the infrared data difference, and further obtains the body temperature of the human body according to the temperature difference and the reference temperature of the thermostat, so that the body temperature of the human body can be accurately detected, and the situation that the air conditioning system cannot accurately adjust the operating parameters according to the body temperature of the indoor personnel over time is avoided.
It should be noted that the infrared data of the present invention may be the intensity of the infrared ray received by the infrared detection module, or may be the gray scale displayed on the infrared image after being processed by the infrared detection module. Wherein, when infrared data is the intensity degree of infrared ray, infrared detection module can be infrared detector, when infrared data is the grey scale on the image, infrared detection module can be infrared thermal imaging sensor.
In addition, the present invention further provides a control method of an air conditioning system, which is different from the human body temperature detection method, and further includes step S201 and step S202 as shown in fig. 2.
As shown in fig. 2, in step S201, an indoor ambient temperature is obtained by a temperature sensor of an air conditioning system, which is provided in an indoor unit of the air conditioning system.
As shown in fig. 2, the body temperature and the indoor ambient temperature control the operation of the air conditioning system in step S202. Specifically, the controller calculates a temperature difference between the body temperature and the indoor environment temperature, and then adjusts the cooling power or the heating power of the air conditioning system according to the magnitude of the temperature difference. Further specifically, when the air conditioning system performs refrigeration, the refrigeration power of the air conditioning system is adjusted according to the size of the temperature difference; and when the air-conditioning system heats, adjusting the heating power of the air-conditioning system according to the temperature difference. Or, as needed, the person skilled in the art may also cause the air conditioning system to execute a heating mode or a cooling mode according to the magnitude of the temperature difference when the air conditioning system is started.
Based on the above description, those skilled in the art can understand that the control method of the air conditioning system of the present invention not only can accurately detect the body temperature of the indoor person, but also can adjust the heating or cooling power of the air conditioning system according to the body temperature and the indoor environment temperature, so that the air conditioning system is more intelligent, the indoor person is more comfortable, and the user experience is optimized.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
