Description

[0001] The present application relates to the field of air conditioning energy saving, and in particular to a method, system, device and storage medium for controlling air conditioning energy saving by using human body sensing. Background Art

[0002] The fan coil unit is abbreviated as fan coil. It is a commonly used cooling and heating terminal device. It is one of the terminal devices of the air conditioning system composed of a small fan, a motor and a coil (air heat exchanger). When chilled water or hot water flows through the coil tube, it exchanges heat with the air outside the tube, so that the air is cooled, dehumidified or heated to adjust the indoor air parameters.

[0003] At present, the control logic of fan coil units in open office areas and conference rooms in office buildings is to start the fan coil units after turning on the air conditioning panel to set the temperature. When the air outlet temperature reaches the set temperature for a certain period of time, the fan stops, the electric valve of the chilled water supply pipe closes, and the fan coil units stop running. However, as long as the temperature is higher than the set value, the fan coil units will start running again, and can only be completely stopped by manually shutting them down on site, resulting in the failure to automatically shut down the fan coil units in the open office area or conference room when no one is there; even the building equipment automatic control system cannot automatically shut down the fan coil units in the unmanned office area; and the air conditioning control has nothing to do with the number of people on duty.

[0025] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are provided in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0027] Figure 1 The flowchart of an embodiment of a method for controlling air conditioning energy saving by human body sensing of the present application is shown, including the steps of:

[0028] Step S1, real-time monitoring of the number of people in a specific area.

[0029] Step S2: output a corresponding trigger signal according to the number of people.

[0030] Step S3, adjusting the operating status of the air conditioning system and the fan coil unit according to the trigger signal.

[0031] The method of the present application can intelligently adjust the energy consumption of the air conditioner by monitoring the number of people in a specific area, so as to achieve the effect of saving electricity resources.

[0032] In some embodiments, step S1 , real-time monitoring of the number of people in a specific area is performed by setting a first number of infrared sensors in the specific area.

[0033] Specifically, the specific area may refer to office areas, conference rooms and other places. An infrared sensor is an electronic device that can receive and sense infrared signals. When someone enters the sensing range of the infrared sensor, it can detect changes in the infrared spectrum of the human body, thereby monitoring the number of people in the specific area. Exemplarily, the first number may be 2, that is, 2 infrared sensors may be set in each specific area. It should be noted that the above is only an example and cannot be used as a limitation on the scope of protection of this application.

[0034] Furthermore, according to the number of people monitored by the infrared sensor, a corresponding trigger signal is output to adjust the operating status of the air conditioning system and the fan coil unit. The operating status of the air conditioning system and the fan coil unit includes: closing the water valve of the air conditioning system and the fan coil unit, or putting the air conditioning system in air supply mode and closing the water valve of the fan coil unit, or putting the air conditioning system in cooling mode and opening the water valve of the fan coil unit. The specific operating status of the air conditioning system and the fan coil unit is determined according to the received trigger signal.

[0035] In some embodiments, the step of real-time monitoring the number of people in a specific area and outputting a corresponding trigger signal according to the number of people also includes: when the number of people monitored meets the first threshold condition, outputting a first trigger signal to the building equipment automatic control system; the building equipment automatic control system adjusts the air-conditioning system and the fan coil to the first operating state according to the first trigger signal.

[0036] For example, when the number of people in a specific area is monitored to be 0, that is, when the first threshold condition is 0, that is, when there is no one, the first trigger signal is output to the building equipment automatic control system. Among them, the building equipment automatic control system is an integrated general term for systems such as cold and heat source systems, air conditioning and ventilation systems, fan coil systems, elevator systems, and drainage systems. The building equipment automatic control system mainly manages and controls various types of equipment in the building efficiently through operating status monitoring and fault monitoring. The building equipment automatic control system can also greatly reduce energy consumption while providing the best comfortable environment and modern management mode. Therefore, it is widely used in buildings such as offices, hotels, hospitals, and shopping malls.

[0037] Furthermore, the building equipment automatic control system turns off the water valves of the air conditioning system and the fan coil according to the first trigger signal, that is, the first operating state. In this way, the fan coil and air conditioning in the open office area and conference room can be automatically turned off when no one is in the area, so as to achieve the effect of reducing energy consumption.

[0038] In some embodiments, the steps of real-time monitoring the number of people in a specific area and outputting a corresponding trigger signal according to the number of people also include: when the number of people monitored meets the second threshold condition, outputting a second trigger signal to the building equipment automatic control system; the building equipment automatic control system adjusts the air-conditioning system and the fan coil to the second operating state according to the second trigger signal.

[0039] For example, when the number of people in the specific area is monitored to be 1, that is, when the second threshold condition is 1, that is, when there is only one person in the specific area, the second trigger signal is output to the building equipment automatic control system. Further, the building equipment automatic control system adjusts the air conditioning system to the air supply mode and closes the water valve of the fan coil according to the second trigger signal, that is, the second operating state. This method can not only provide a comfortable environment for users, but also achieve energy-saving effects.

[0040] In some embodiments, the steps of real-time monitoring the number of people in a specific area and outputting a corresponding trigger signal according to the number of people also include: when the number of people monitored meets the third threshold condition, outputting a third trigger signal to the building equipment automatic control system; the building equipment automatic control system adjusts the air-conditioning system and the fan coil to a third operating state according to the third trigger signal.

[0041] For example, when the number of people in a specific area is monitored to be more than one, that is, when the third threshold condition is at least two people, that is, when there are at least two people in the specific area, a third trigger signal is output to the building equipment automatic control system. Further, the building equipment automatic control system adjusts the air conditioning system to be in cooling mode and opens the water valve of the fan coil according to the third trigger signal, that is, the third operating state. This method can achieve a better cooling effect in the case of multiple people and provide a more comfortable environment for people in a specific area.

[0042] In some embodiments, the step of adjusting the operating status of the air-conditioning system and the fan coil unit according to the trigger signal also includes: the trigger signal is also input into a decoder, the decoder outputs a logic signal to a relay according to the trigger signal, and the relay controls the opening and closing of the air-conditioning system and the fan coil unit according to the logic signal.

[0043] For example, Figure 2 The following is a schematic diagram of the decoder. When a person enters the sensing range of the infrared sensor, the infrared sensor automatically outputs a high-level signal (MSB), and continues to output a high-level signal as long as the person does not leave the sensing range; when the person leaves the sensing range, the infrared sensor automatically turns off the output of a low-level signal (LSB) after a delay. Therefore, the trigger signal of the infrared sensor is a low-level signal or a high-level signal.

[0044] Furthermore, when there is no trigger signal from both sensors, that is, when there is no one in a specific area, the signal at the input end of the decoder is 00, and the Y0 output end of the decoder outputs a logic signal; the relay receives the logic signal output by the Y0 end of the decoder, and closes the water valve of the air conditioning system and the fan coil according to the logic signal. In this way, the fan coil and air conditioning in the open office area and conference room can be automatically closed when no one is there, so as to achieve the effect of reducing energy consumption.

[0045] Furthermore, when only one of the two sensors has a trigger signal, and the signal at the input end of the decoder is 01 or 10, the Y1 and Y2 output ends of the decoder are connected in parallel, and the logic signal output by any output end of Y1 and Y2 can adjust the air conditioning system to the air supply mode and close the water valve of the fan coil. This method can not only provide users with a comfortable environment, but also achieve energy-saving effects.

[0046] Furthermore, when there are trigger signals in both sensors, that is, when the signal at the input end of the decoder is 11, the Y3 output end of the decoder outputs a logic signal, so that the air conditioning system is in cooling mode and the water valve of the fan coil is turned on. This method can achieve a better cooling effect in the case of multiple people, providing a more comfortable environment for people in a specific area.

[0047] Combination Figure 3The present application also provides an air conditioning energy-saving system using human body sensing control, including a monitoring module 31, a trigger module 32 and a control module 33 connected in sequence.

[0048] The monitoring module 31 is used to monitor the number of people in a specific area in real time.

[0049] The trigger module 32 is used to output a corresponding trigger signal according to the number of people.

[0050] The control module 33 is used to adjust the operating status of the air conditioning system and the fan coil unit according to the trigger signal.
