[0001] The present invention relates to the field of smart home technology, and in particular to an air conditioning control system and method based on a temperature correction model. Background Art
[0002] Currently, patents on air-conditioning control systems and methods mainly focus on the use of intelligent control technology, ignoring previous research, experiments and simulation expansion. This patent is based on the room temperature and humidity distribution characteristics discovered through experimental exploration and the relationship model between the set temperature and the average temperature and humidity of the working area of the air-conditioned room.
[0003] Experimental studies have found that there are obvious differences in horizontal temperature and humidity in air-conditioned rooms under air-conditioned environments. The area with the most obvious horizontal temperature and humidity characteristics is the area directly facing the air conditioning. In order to make full use of the cold and heat energy prepared by air-conditioning equipment, it is crucial to energy save the air in the air-conditioned room by zoning the air supply according to the areas where people are located.
[0004] At present, the opening and status change of air-conditioning equipment are all done manually when the air conditioner is already in a thermally uncomfortable condition, and most of the time the opening and status change depends on human habits and randomness. In addition, residents do not understand the use of the function keys on the air-conditioning product panel. Therefore, it is very important to open and control indoor air-conditioning equipment conveniently, scientifically, comfortably and energy-savingly. Summary of the invention

[0022] When the number of people in the room n=0, the person leaving the room time module records the time when the person leaves the room.
[0023] When the number of people in the room n>0, the people-in-room time module records the people-in-room time.
[0024] When the number of people in the frequent activity area>0, the people-in-frequent-activity-area time module records the time the people spend in the frequent activity area.

When the indoor average temperature and humidity are unstable, the analysis and decision-making module sends the air conditioner temperature adjustment signal to the control module. When the indoor average temperature and humidity are stable, the analysis and decision-making module calculates the indoor average stable temperature T using the average stable temperature calculation model R =(a1t S +a2)W+(a3t S +a4); where the fitting coefficient a m =b 1m L 2 +b 2m L+b3m ; The coefficient serial number m = 1, 2, 3, 4; a m , b 1m , b 2m , b 3m are fitting coefficients; L is the length of the indoor space; W is the width of the indoor space; t s is the set temperature value of the air conditioner; if the indoor average stable temperature T R is not within the comfortable temperature range, then the analysis and decision-making module sends an air conditioner temperature adjustment signal to the control module;

[0063] Among them, T j and T1 respectively represent the last item and the first item element in the indoor average temperature dataset. RH j and RH1 respectively represent the last item and the first item element in the indoor average humidity dataset.
[0064] When the elements in the indoor average temperature dataset and the indoor average humidity dataset do not satisfy the temperature and humidity stabilization judgment condition I, the temperature and humidity stabilization judgment condition II, and the temperature and humidity stabilization judgment condition III, the indoor average temperature and humidity are unstable.

[0136] The timing device includes a time module for personnel leaving the room, a time module for personnel staying in the room, a time module for personnel not being in a frequent activity area, a time module for personnel being in a frequent activity area, a time module for personnel being in a non-frequent activity area, and a time module for personnel not being in a non-frequent activity area.
[0137] When the number of people in the room n=0, the person leaving the room time module records the time when the person leaves the room.
[0138] When the number of people in the room n>0, the people-in-room time module records the people-in-room time.
[0139] When the number of people in the frequent activity area>0, the people-in-frequent-activity-area time module records the time the people spend in the frequent activity area.
[0140] When the number of people in the frequent activity area=0, the people-in-frequent-activity-area time module records the time when the people are not in the frequent activity area.
[0141] When the number of people in the infrequent activity area>0, the people-in-infrequent-activity-area time module records the time the people spend in the infrequent activity area.
[0142] When the number of people in the infrequent activity area=0, the people-in-infrequent-activity-area time module records the time when the people are not in the infrequent activity area.
[0143] Several infrared distance measuring devices are arranged on the air conditioner to monitor the indoor space distance infrared signal and the relative position information between the air conditioner and different indoor areas. The relative position can be directly filled in by the user into the intelligent control device without the need for infrared distance measuring device monitoring, and the infrared distance measuring device can be omitted.
[0144] The infrared distance measuring device comprises an infrared distance measuring instrument, a photographing device and a signal exchanger.
[0145] The infrared rangefinders are respectively installed on the front, back, left and right walls of the air conditioner. The four infrared rangefinders are in the same horizontal plane.
[0146] Referring to FIG. 12( a ), the infrared rangefinders 1 are respectively installed on the top of the two side walls of the air conditioner, and are respectively denoted as infrared rangefinder I, infrared rangefinder II, infrared rangefinder III, and infrared rangefinder IV; the four infrared rangefinders are in the same horizontal plane; the infrared rangefinder I is perpendicular to the front of the air conditioner, the infrared rangefinder II is perpendicular to the back of the air conditioner, the infrared rangefinder III is perpendicular to the left wall of the air conditioner; the infrared rangefinder IV is perpendicular to the right wall of the air conditioner; the four infrared rangefinders are all perpendicular to the ground; when the air conditioner is equivalent to a rectangle, the position of the infrared rangefinder 1 is shown in FIG. 12( b ).
[0147] When the infrared rangefinder is working, it rotates unidirectionally periodically, and each rotation angle is α;
[0148] The infrared rangefinder sends infrared rays outward and receives infrared reflection signals;
[0149] The infrared rangefinder sends the infrared reflection signal to the intelligent control device through the signal exchanger;
[0150] The photographing device is arranged indoors to take images of the indoor space including the air conditioner, and sends the images of the indoor space to the intelligent control device through a signal exchanger.
[0151] The photographing device photographs an image of the indoor space including the air conditioner, and sends the image of the indoor space to the intelligent control device through a signal exchanger.
[0152] The intelligent control device uses an existing image recognition algorithm to identify the position of the air conditioner in the indoor space, and uses it together as auxiliary information of the relative position information of the air conditioner and different indoor areas;
[0153] The recognition method is: pre-store the feature information of each indoor device (including RGB value, pixel information), use the image recognition algorithm to extract the indoor space image features, and match them with the stored feature information to obtain the location of each device in the indoor space. The devices include air conditioners, sofas, tables and other furniture.
[0154] The intelligent control device uses an image recognition algorithm to identify the indoor space image to obtain a ratio X of the relative length and relative width between the air conditioner and the side wall; the relative position of the air conditioner and the indoor area includes the relative length and relative width between the air conditioner and the side wall.
[0155] The intelligent control device adds the infrared reflection signals of the infrared rangefinder I and the infrared rangefinder III in each cycle to obtain the diagonal measurement result I of the cycle, adds the infrared rangefinder II and the infrared rangefinder IV in each cycle to obtain the diagonal measurement result I of the cycle, and takes the maximum value of the diagonal measurement results I and II in all cycles as the infrared rangefinder measurement result. When measuring, the width of the air conditioner can be added or ignored.
[0156] The measurement result of the infrared rangefinder is used as the longest side of the right triangle, and the indoor area length L and indoor area width H are used as the right angle sides. The indoor area length L and indoor area width H are determined using the Pythagorean theorem. When there are multiple values for the indoor area length L and indoor area width H, the ratio X1 of the indoor area length and indoor area width H, the ratio X2 of the relative length between the air conditioner and the side wall, and the relative width between the air conditioner and the side wall are calculated, and the indoor area length L and indoor area width H with the smallest ratio difference |X1-X2| are used as the relative length between the air conditioner and the side wall and the relative width between the air conditioner and the side wall. When the Pythagorean theorem is used to determine the indoor area length L and indoor area width H, the length and width may not necessarily conform to the Pythagorean theorem. When the infrared rays are blocked by an object in the room, the sum of the squares of the length and width is not equal to the sum of the squares of the diagonals. The pre-selected length and width in the test process are the sum of the distances of the two infrared rays, and the one closest to the Pythagorean theorem (i.e., a set of L and H is selected so that it is closest to the length and width values that satisfy the Pythagorean theorem) shall prevail. At the same time, photos are used to determine the normality of distance measurement, so as to filter out the final data.
[0157] The intelligent control device includes a receiving module, a storage module, an analysis and decision module, a calculation module and a control module.
[0158] The receiving module receives signals sent by the date and time sensing device, a plurality of personnel sensing devices, a plurality of infrared distance measuring devices, a temperature and humidity sensing device, and a timing device respectively, and stores the signals in the storage module.
[0159] The receiving module sends the received monitoring start signal I to the control module.
[0160] The receiving module sends the human infrared sensing signal, the indoor space distance infrared signal and the relative position information between the air conditioner and different indoor areas to the calculation module.
[0161] The receiving module sends the indoor personnel residence time t1, the personnel leaving time, the personnel residence time in different indoor areas, the personnel leaving time in different indoor areas, and the temperature and humidity information to the analysis and decision module.
[0162] After receiving the infrared sensing signal from the human body, the calculation module calculates the number of people in the room. The indoor area where the personnel are located and the number of personnel in different indoor areas are sent to the analysis and decision module. When the calculation module receives the infrared sensing signal sent by the i-th personnel sensing device that the person enters the room, ni=ni+1 is updated. When the calculation module receives the infrared sensing signal when the person leaves the room, ni=ni-1 is updated. The initial value of ni is 0. The indoor area where the personnel are located is the indoor area where the personnel sensing device ni>0 is located.
[0163] After receiving the indoor space distance infrared signal and the relative position information between the air conditioner and different indoor areas, the calculation module calculates the size of the indoor space and the relative position between the air conditioner and different indoor areas, and sends them to the analysis and decision module.
[0164] The analysis and decision module determines whether the number of indoor personnel n>0 is established, and if so, sends a timing start signal to the control module.
[0165] The analysis and decision module retrieves the residence time threshold tmax1 stored in the storage module and compares it with the indoor personnel residence time t1. When t1≥tmax, a temperature and humidity sensing signal is sent to the control module.
[0166] The analysis and decision module retrieves the time threshold tmax2 stored in the storage module and compares it with the time the person leaves the room. When the time the person leaves the room is ≥ tmax2, an air conditioning shutdown signal is sent to the control module.
[0167] The analysis and decision module analyzes the indoor areas where people are located, the number of people in different indoor areas, the relative positions of air conditioners and different indoor areas, the time people stay in different indoor areas, and the time people leave different indoor areas.
[0168] When the indoor area where the person is located is a frequent activity area and the person stays in the frequent activity area for longer than the time threshold tmax3, a frequent activity area wind direction control signal is sent to the control module.
[0169] When the indoor area where the person is located is a non-frequent activity area and the person stays in the non-frequent activity area for a time greater than the time threshold tmax4, a wind direction control signal for the non-frequent activity area is sent to the control module.
[0170] When the number of people in the frequent activity area is greater than the number of people in the infrequent activity area, a wind direction adjustment signal I is sent to the control module. When the number of people in the frequent activity area is equal to the number of people in the infrequent activity area, a wind direction adjustment signal II is sent to the control module. When the number of people in the frequent activity area is less than the number of people in the infrequent activity area and the people stay in the infrequent activity area for <30 minutes, a wind direction adjustment signal II is sent to the control module; when the number of people in the frequent activity area is less than the number of people in the infrequent activity area and the people stay in the infrequent activity area for ≥30 minutes, a wind direction adjustment signal III is sent to the control module;
[0171] After receiving the size of the indoor space, the analysis and decision module retrieves the local climate information stored in the storage module, generates the temperature adjustment range under different date and time nodes, and inputs it into the temperature setting model.
[0172] The analysis and decision module retrieves the average temperature and humidity calculation model stored in the storage module, and inputs the temperature and humidity information into the average temperature and humidity calculation model to calculate the indoor average temperature and humidity. The analysis and decision module writes the indoor average temperature into the indoor average temperature data set and the indoor average humidity into the indoor average humidity data set in chronological order.
[0173] Average indoor temperature Average indoor humidity Where n = 10, n is a positive integer; T i is the temperature at the i-th moment, and RHi is the humidity at the i-th moment. i is the moment of the previous i-th temperature and humidity monitoring with the current moment as the zero point. When the air conditioner is turned off, the analysis and decision module calls the temperature and humidity over-limit judgment model stored in the storage module, and inputs the indoor average temperature data set and the indoor average humidity data set into the temperature and humidity over-limit judgment model. If at least one element in the indoor average temperature data set is not within the temperature range of the temperature and humidity over-limit judgment model or at least one element in the indoor average humidity data set is not within the humidity range of the temperature and humidity over-limit judgment model, a monitoring start signal II and an air conditioning start signal are sent to the control module.
[0174] When the air conditioner is turned on, the analysis and decision module retrieves the temperature and humidity stabilization judgment model stored in the storage module, and inputs the indoor average temperature data set and the indoor average humidity data set into the humidity stabilization judgment model to judge whether the indoor average temperature and humidity are stable. When the indoor average temperature and humidity are unstable, the analysis and decision module sends an air conditioner temperature adjustment signal to the control module. When the indoor average temperature and humidity are stable, the analysis and decision module calculates the indoor average stable temperature T using the average stable temperature calculation model. R =(a1t S +a2)W+(a3t S +a4); where the fitting coefficient a m =b 1m L 2 +b 2m L+b 3m ; Coefficient number m = 1, 2, 3, 4; a m 、b 1m 、b 2m 、b 3m is the fitting coefficient; L is the length of the indoor space; W is the width of the indoor space; t s Set the temperature value for the air conditioner; if the average indoor temperature is stable, T R If the temperature is not within the comfortable temperature range, the analysis and decision module sends an air conditioning temperature adjustment signal to the control module; R =AW+B; A=a1T S +a2,B=a3T S +a4.

[0302] When the air conditioner is initially turned on, the set temperature is the recommended boundary setting value in the initial setting temperature model (summer is the upper limit of the initial boundary value, and winter is the lower limit of the initial boundary value), but the initial default setting wind direction is horizontal, and the left and right wind direction depends on the area where the indoor personnel are located;
[0303] Whether the setting state of the air conditioning device is changed depends on whether the average temperature of the working area of the room converted by the temperature model of the current setting temperature is stably within the comfort zone and whether the area where the indoor personnel are located is changed.

[0330] When the temperature sensing device at the return air outlet senses that the temperature exceeds the upper and lower limits of the human body's acceptable temperature in the corresponding season, the personnel sensing devices at the boundaries of each area of the linkage intelligent control device are activated;
[0331] The intelligent control device analyzes the initial default wind direction based on the comprehensive situation of all personnel sensing devices; and controls the air conditioning equipment to start according to the initial default state;
[0332] After the air conditioner is turned on, the intelligent control device will periodically decide whether to change the set wind direction of the air conditioner or turn off the air conditioner based on the feedback information from the indoor occupant sensing device and the timing device. It can also change the set wind direction of the air conditioner at irregular intervals according to the requirements of the indoor occupants and receive the stored status value.
[0333] When the air conditioning equipment is turned off, all other devices except date and time sensors, room entrances and exits, and personnel sensors in areas where people may move frequently must be turned off at the same time;
[0334] The intelligent control device will periodically request the return air outlet temperature and humidity sensing device to transmit a temperature signal according to the time after the air conditioning equipment changes the on / off or setting state and the time length meets the requirements within a period of time, so as to comprehensively determine whether the room temperature and humidity in the air-conditioned environment are in a stable state;
[0335] When the intelligent control device determines that the room temperature and humidity under the air-conditioning environment are in a stable state, the corresponding temperature model is immediately selected according to the current air-conditioning equipment type, air-conditioning use season, air-conditioning room size and air-conditioning installation location) and the average temperature of the current room working area is estimated through the setting temperature of the current air-conditioning equipment stored in the intelligent control device. If so, the current setting state is maintained; if not, the air-conditioning setting temperature is adjusted to the current median value of the setting temperature model, and the boundary value and median value of the setting temperature model are reassigned;
[0336] When the intelligent control device determines that the room temperature and humidity in the air-conditioned environment are in an unstable state, it immediately requires the return air outlet temperature sensing device to transmit temperature and humidity signals according to the previous period of time and converts the temperature and humidity correction model to determine whether the room temperature and humidity in the air-conditioned environment are close to the comfortable temperature and humidity range. If so, the current setting state is maintained and it is required to determine whether the room temperature and humidity in the air-conditioned environment are in a stable state at regular intervals and repeat the action after determining the stability. If not, the air-conditioning set temperature is adjusted to the current median value of the set temperature model, and the boundary value and median value of the set temperature model are reassigned. It is still required to determine whether the room temperature and humidity in the air-conditioned environment are in a stable state at regular intervals and repeat the action after determining the stability.
[0337] The temperature model at least includes:
[0338] The temperature model refers to the relationship model between the set temperature of the air-conditioning equipment and the average stable temperature of the room working area under the winter and summer operation modes of the bedroom wall-mounted air conditioner (upper delivery and upper return) and the living room cabinet air conditioner (central delivery side and lower return, central delivery positive and lower return, central delivery and rear central return) of the residential building. The form of the relationship model and the correlation coefficient in the form are shown in Appendix 1;
[0339] The intelligent control device will select and select the temperature model that matches the current air-conditioning room environment according to the current air-conditioning equipment type, air-conditioning use season, air-conditioning room size and air-conditioning installation location, and estimate the average stability of the room working area according to the set temperature of the current room air-conditioning equipment;
[0340] Setting the temperature model and setting the temperature-related boundary values and median values includes at least:
[0341] The components of the set temperature model are the set temperature boundary value and the median value of the established air-conditioned room. Since the set temperature model is further calculated based on the established temperature model of the current air-conditioned room, the components of the set temperature model are jointly determined by objective factors such as the form of the air-conditioning equipment, the season in which the air-conditioning is used, the size of the air-conditioned room, and the installation location of the air-conditioning;
[0342] The boundary value and median value of the set temperature model will be adjusted as the current set temperature changes. When the air conditioner set temperature is adjusted to the current median value of the set temperature model as needed, the boundary value in the set temperature model is reassigned to the median value and one of the boundary values in the previous step of the set temperature model (the lower limit of the boundary value in the previous step in summer and the upper limit of the boundary value in the previous step in winter);
[0343] The intelligent control device calculates the initial temperature boundary value and median value of the current room setting based on the average stable temperature comfort range of the room working area, thereby forming an initial setting temperature model. The average stable temperature comfort range of the room working area is between 24-28℃ in summer and between 18-24℃ in winter.
[0344] The four corners are divided into two groups with the diagonal of the air conditioner as a reference, and the two groups of corners are assumed to be two parallel planes, one group of planes is attached to and parallel to the front and back of the air conditioner, and the other group of planes is attached to and parallel to the left and right sides of the air conditioner. The one-way infrared rangefinders are also installed in this grouping manner and bound to each other and numbered (1-4), where the four rangefinders 1 and 2 are a group (for measuring width), and 3 and 4 are a group (for measuring length);
[0345] The four one-way infrared rangefinders are respectively perpendicular to the four angular surfaces mentioned above and respectively perpendicular to the ground and are horizontally installed at the highest points of the four angular surfaces of the air conditioner relative to the ground.
[0346] Four rotatable one-way infrared rangefinders, including at least:
[0347] The infrared rays are emitted unidirectionally for distance measurement. The initial emission direction is vertical and facing away from the imaginary angular surface on which it is installed. The distance measured in the initial direction will be fed back to the intelligent control device.
[0348] After measuring the distance in the initial transmission direction, the four rotatable one-way infrared rangefinders will continue to rotate and measure the distance on the surface of the air conditioner, measuring the distance at a certain angle (5° is recommended, and the maximum rotation angle is 90°), and each distance measurement will be fed back to the intelligent control device;
[0349] The intelligent control device performs processing and calculation to determine the approximate size of the room where the air conditioner is currently to be operated (ignoring the size of the air conditioner itself), including:
[0350] The distances fed back from the initial direction of the infrared distance measuring device are added diagonally and stored as the default length and width of the air-conditioned room respectively;
[0351] The intelligent control device stores, adds and stores the distance feedback from the four infrared testers in the order of testing. After a total of 18 distance measurements, the two groups of distances after addition are compared. The largest added distance is used as the diagonal distance of the air-conditioning room, and the length and width of the air-conditioning room are verified and corrected by the Pythagorean theorem to determine the final size of the air-conditioning room.
[0352] The method of determining the installation location of the air conditioner by distance conversion and photographed pictures includes:
[0353] The installation location is determined after the size of the air-conditioned room is finalized;
[0354] The distance conversion is carried out by group (the groups are divided into groups according to the distance meters, with a total of two groups). When determining the installation position, the distance conversion is mainly based on the distance of the final air-conditioned room size. The distance between the two distance meters 1 and 2 is divided by the width; the distance between the two distance meters 3 and 4 is divided by the length. The installation position of the air-conditioned room is preliminarily determined according to the calculation ratio.
[0355] The pictures taken can determine the furniture arrangement around the current air conditioner location. For example, for a cabinet in the living room, it can be determined whether it is installed next to the TV or the sofa. The general idea is as follows:
[0356] The purpose of diagonal conversion is to prevent certain distances from being blocked by furniture when measuring distance (the blue line in the figure is the initial length when there is no furniture blocking it, and the red line is the diagonal length). The infrared rangefinder (orange circle) should be installed at the top of the air conditioner where the furniture blocks less infrared rays.
[0357] Embodiment 5:
[0358] The method of using the air conditioning control system based on the temperature correction model comprises the following steps:
[0359] 1) Determine whether the air conditioner on information node has been reached through the date and time sensing device. If so, proceed to step 2; otherwise, proceed to step 4.
[0360] The date and time sensing device makes a judgment and response at the information node based on the preset date and time node information. If it is judged that the preset date and time node that meets the requirements for turning on the air conditioner is reached, the intelligent control device is turned on and the signal is transmitted to the intelligent control device and the process proceeds to step 2. Otherwise, the process proceeds to step 4.
[0361] 2) Comprehensively judge whether there is a person in the room through the personnel sensing device and timing device in the corresponding area. If so, go to step 3; otherwise, go to step 4.
[0362] Through the personnel sensing devices and timing devices at the entrances and exits of the room and areas where personnel may frequently move, it is comprehensively judged whether there are people in the room for a long time. If so, the signal is transmitted to the intelligent control device and the process goes to step 3. Otherwise, the process goes to step 4.
[0363] 3) Use the temperature sensing device at the return air outlet to sense whether the room temperature reaches the upper and lower limits. If so, proceed to step 5; otherwise, proceed to step 4.
[0364] When the intelligent control device obtains the node information from the date and time sensing device through step 1, and comprehensively determines that there are people in the room outside the time through the information from the personnel sensing device and the timing device in step 2, it immediately controls the temperature sensing device at the return air outlet to sense the current room temperature. If the current room temperature is received and it is determined that the current room temperature reaches the upper or lower limit of the local area and the season, it goes to step 5; otherwise, it goes to step 4.
[0365] 4) Keep the air conditioner off or turn it off.
[0366] 5) Integrate the information from the infrared distance measuring device, the personnel sensing device and the timing device to determine the size of the air-conditioned room, the installation location of the air-conditioning equipment and the situation of personnel in each area.
[0367] When the intelligent control device determines through step 3 that the current room temperature has reached the upper or lower limit, it controls the activation of the infrared ranging device and the personnel sensing devices at the boundaries of each area, and each personnel sensing device will also link the timing device to the corresponding module timing; the intelligent control device comprehensively determines the size of the air-conditioned room, the installation location of the air-conditioning equipment, the number of people in the room, and the situation of people in each area by receiving information from the infrared ranging device, the personnel sensing device and the timing device.
[0368] 6) The air conditioner is turned on in the default setting state (the set temperature is the boundary setting value recommended by the current set temperature model, and the initial air direction of the air conditioner is set according to the situation of personnel in each area).
[0369] The default setting temperature is the recommended boundary setting value in the current setting temperature model, where the default setting temperature in summer is the upper limit of the boundary value of the setting temperature model, the default setting temperature in winter is the lower limit of the boundary value of the setting temperature model, and the default setting wind speed is low speed. The air conditioning wind direction setting requires that the air conditioning equipment can at least sweep the wind, and it is recommended that the wind direction of the air conditioning equipment can be customized; on this basis, the intelligent control device is set according to the proportion of people in each area.
[0370] If the room is only divided into living area and non-living area. And the location information of living area and non-living area can be entered into the intelligent control device through the application or the initial setting of the device; when there are people in both the living area and the non-living area, but the number of people in the living area is greater than that in the non-living area, the air-conditioning equipment sweeping mode is turned on, and it is recommended that the wind direction stay in the living area for more than 1 / 3 of the non-living area per cycle; when there are people in both the living area and the non-living area and the number of people is equal, the air-conditioning equipment sweeping mode starts and it is recommended that the wind direction stay in the living area for the same time as the non-living area per cycle; when there are people in only one area of the living area and the non-living area, the air supply of the air-conditioning equipment needs to be directed to the area with people.
[0371] 7) Check and update the boundary values and median values recommended by the current model, and decide on the start and stop and setting status of the air conditioner based on the comprehensive feedback information of each personnel sensing device and timing device or based on the irregular requirements of indoor personnel (the feedback requirements of indoor personnel have priority). After the air conditioner is turned off, except for some necessary personnel sensing devices, date and time sensing devices, all other devices will immediately stop analyzing and be turned off.
[0372] After turning on the air conditioner according to the initial setting state through step 6, the current model boundary value and median value remain unchanged temporarily; when the indoor personnel request the air conditioner to start or close and change the setting state through the remote control device or application, the intelligent control device immediately receives the signal and changes it, and still operates according to the control method after the change. However, since the personnel sensing device will convert the signal and transmit it to the intelligent control device according to the change of the indoor personnel, the personnel sensing device will also link the corresponding module of the timing device to start or close and time accordingly, and the timing node signal will also be transmitted to the intelligent control device; in other words, the intelligent control device will always receive the indoor personnel change situation and the indoor and outdoor time node information, the time in each area and the time node information of the absence in each area, and comprehensively judge whether the air conditioner is turned on or off based on this information; if it remains on, the wind direction will be changed if the indoor personnel situation changes, and the wind direction setting is still set according to the current proportion of personnel in each area; when the air conditioner is turned off according to the control logic and human requirements, except for the personnel sensing device at the entrance and exit of the air-conditioned room and the personnel sensing device in the area where personnel may frequently exist, the other devices will immediately stop analyzing and turn off.
[0373] When a person in the room requests a change in the setting state twice in a short period of time, the intelligent control device will receive the signal and immediately change the setting state according to the person's request, and request to stop the operation of the current control method.
[0374] 8) Determine whether the room temperature and humidity are stable based on the time and return air outlet temperature and humidity signals. If so, proceed to step 9; otherwise, proceed to step 210.
[0375] Whether the temperature and humidity in the air-conditioned room are stable depends on the intelligent control device's comprehensive judgment based on the time and the temperature and humidity signals fed back from the return air outlet within a period of time after the time length is met; the time length refers to the time when the timing starts after the air conditioner is turned on or changes its state. The timing of this time is completed by the calculation module of the intelligent control device, which means that once the intelligent control device receives a signal that the air conditioner is turned on or the setting state is changed, the receiving module will remind the calculation module in the device to start timing; when the timing time reaches 30 minutes, the intelligent control device will require the temperature and humidity sensing device at the return air outlet to feedback the temperature and humidity at the return air outlet every 1 minute within 10 minutes, and use this as the basis for judging whether the temperature and humidity in the room are stable.
[0376] When the timing time of the calculation module of the intelligent sensing device reaches 30 minutes and the temperature and humidity sensed at the return air outlet within 10 minutes are received, it will judge whether the room temperature and humidity are stable according to the following logic: the intelligent control device will perform pairwise difference calculations on the 10 air temperatures sensed within 10 minutes and temporarily store them in the storage module, and analyze the extreme values of the air temperature within 10 minutes, that is, the maximum and minimum values, and calculate the difference between the maximum and minimum values. If the absolute values of the calculation results within 10 minutes are all less than 2°C, it can be considered that the indoor air temperature is stable; similarly, the 10 air humidities sensed within 10 minutes are performed pairwise difference calculations and temporarily stored in the storage module, and analyze the extreme values of the air humidity within 10 minutes, that is, the maximum and minimum values, and calculate the difference between the maximum and minimum values. If the absolute values of the calculation results within 10 minutes are all less than 3%, it can be considered that the indoor air humidity is stable.
[0377] 9) The intelligent control device comprehensively analyzes whether the room temperature is within the comfort zone based on the temperature correction model. If so, it proceeds to step 11, otherwise, it proceeds to step 12.
[0378] When the intelligent control device determines that the room temperature and humidity are in a stable state, the calculation module will use the temperature correction model in the storage module and the current feedback of the air-conditioning equipment setting temperature to estimate the current room average temperature and humidity, and then compare it with the local temperature comfort zone range of the season in the storage module; if the room average temperature is within the local temperature comfort zone range of the season, go to step 11, otherwise go to step 12.
