In order to solve the above problems, in a typical embodiment of the present application, an air conditioner outlet opening degree control method, control device, computer readable storage medium and air-conditioned passenger car are provided.

[0024] According to the embodiments of the present application, an air conditioner outlet opening degree control method is provided. The space where the air conditioner is located includes a plurality of regions, and each region includes at least one outlet of the air conditioner.

[0025] Figure 1 is a flow chart of the air conditioner outlet opening degree control method according to the embodiments of the present application. As shown in Figure 1 , the method comprises the following steps:

[0026] Step S101, in the case that the difference between the current environmental temperature and the target temperature is within a predetermined interval and the change rate of the environmental temperature of the target region is greater than a predetermined change rate, entering an automatic control mode, the target region being any one of the regions;

[0027] In order to ensure that the target region is maintained in the human comfortable temperature interval, in an optional embodiment, before step S101, the method further comprises:

[0028] Step S201, the environment temperature of the target area is acquired once every third predetermined time, and the difference between the current environment temperature and the last environment temperature is calculated to obtain the change rate of the environment temperature of the target area.

[0029] In the above embodiment, as shown in Figure 2 The change of the environment temperature is monitored, the change rate of the environment temperature of the target area is obtained by periodically acquiring the environment temperature of the target area and calculating the difference between the current environment temperature T1 and the last environment temperature T0. If the temperature changes too fast, the environment temperature of the target area cannot be maintained in the human comfortable temperature range, the environment temperature of the target area is monitored, and if the temperature changes too fast, the automatic control mode is entered to ensure that the environment temperature of the target area is maintained in the human comfortable temperature range.

[0030] Step S102, automatic adjustment step, in the case that there is no manual adjustment operation in the current automatic control period, the opening degree of the air outlet of the target area is adjusted according to the environment temperature change to reduce the change of the environment temperature, the current automatic control period is the current automatic control period, the automatic control period is the time period with a length of the first predetermined time after entering the automatic control mode, the automatic control period is continuous, the manual adjustment operation is the operation of manually adjusting the opening degree of the air outlet of the target area, and the environment temperature change is the difference between the environment temperature of the target area at the end of the current automatic control period and the environment temperature of the target area at the beginning of the current automatic control period.

[0031] The automatic control mode is suitable for the cooling mode, in order to ensure that the cooling capacity of the air conditioner is reasonably distributed, in an optional embodiment, the step S102 comprises:

[0032] Step S1021, in the case that the air conditioner is in the cooling mode and the environment temperature change is greater than 0, the opening degree of the air outlet of the target area is increased;

[0033] Step S1022, in the case that the air conditioner is in the cooling mode and the environment temperature change is less than 0, the opening degree of the air outlet of the target area is reduced;

[0034] Step S1023, in the case that the air conditioner is in the cooling mode and the environment temperature change is equal to 0, the current opening degree of the air outlet of the target area is maintained.

[0035] In the above embodiment, as shown in Figure 2As shown, in the cooling mode, if the environmental temperature change amount is greater than 0, i.e. the environmental temperature of the target area at the end of the current automatic control period is greater than the environmental temperature of the target area at the beginning of the current automatic control period, it indicates that the internal environmental temperature of the target area in the current automatic control period has risen, and the opening degree of the air outlet of the target area is increased to reduce the temperature. If the environmental temperature change amount is less than 0, i.e. the environmental temperature of the target area at the end of the current automatic control period is less than the environmental temperature of the target area at the beginning of the current automatic control period, it indicates that the internal environmental temperature of the target area in the current automatic control period has fallen, and the opening degree of the air outlet of the target area is reduced to increase the temperature. If the environmental temperature change amount is equal to 0, i.e. the environmental temperature of the target area at the end of the current automatic control period is equal to the environmental temperature of the target area at the beginning of the current automatic control period, it indicates that the internal environmental temperature of the target area in the current automatic control period has not changed, and the current opening degree of the air outlet of the target area is maintained. All the areas are controlled in the above-mentioned manner to control the opening degree of the air outlet, which can avoid the situation that some areas have too much cold air and the people feel too cold, and the situation that some areas have too little cold air and the people feel too hot, so as to ensure that the air conditioning cooling capacity is reasonably distributed, the target area is kept in the human comfortable temperature interval, and the comfort of the people is improved.

[0036] The automatic control mode for controlling the opening degree of the air outlet of the air conditioner is also applicable to the heating mode. In order to ensure that the air conditioning heating capacity is reasonably distributed, in an optional embodiment, the above-mentioned step S102 includes:

[0037] Step S1024, in the case that the above-mentioned air conditioner is in the heating mode and the above-mentioned environmental temperature change amount is greater than 0, the opening degree of the above-mentioned air outlet of the above-mentioned target area is reduced;

[0038] Step S1025, in the case that the above-mentioned air conditioner is in the heating mode and the above-mentioned environmental temperature change amount is less than 0, the opening degree of the above-mentioned air outlet of the above-mentioned target area is increased;

[0039] Step S1026, in the case that the above-mentioned air conditioner is in the heating mode and the above-mentioned environmental temperature change amount is equal to 0, the current opening degree of the above-mentioned air outlet of the above-mentioned target area is maintained.

[0040] In the above-mentioned embodiment, as Figure 2As shown, in the cooling mode, if the environmental temperature change amount is greater than 0, i.e. the environmental temperature T3 of the target area at the end of the current automatic control period is greater than the environmental temperature T2 of the target area at the beginning of the current automatic control period, it indicates that the internal environmental temperature of the target area in the current automatic control period has increased, and the opening degree of the air outlet of the target area is increased to reduce the temperature. If the environmental temperature change amount is less than 0, i.e. the environmental temperature T3 of the target area at the end of the current automatic control period is less than the environmental temperature T2 of the target area at the beginning of the current automatic control period, it indicates that the internal environmental temperature of the target area in the current automatic control period has decreased, and the opening degree of the air outlet of the target area is reduced to increase the temperature. If the environmental temperature change amount is equal to 0, i.e. the environmental temperature T3 of the target area at the end of the current automatic control period is equal to the environmental temperature T2 of the target area at the beginning of the current automatic control period, it indicates that the internal environmental temperature of the target area in the current automatic control period has not changed, and the current opening degree of the air outlet of the target area is maintained. All the areas are controlled in the above-mentioned manner to control the opening degree of the air outlet, which can avoid that some areas are too cold and some areas are too hot, ensure that the air conditioning cooling capacity is reasonably distributed, keep the target area in the human comfortable temperature interval, and improve the comfort of the personnel.

[0041] In step S103, the above-mentioned automatic adjustment step is repeated until the above-mentioned manual adjustment operation exists in the above-mentioned current automatic control period, and the above-mentioned automatic control mode is exited.

[0042] In order to ensure that the target area remains in the human comfortable temperature interval, in an optional embodiment, the step S103 comprises:

[0043] In step S1031, a first acquisition step starts timing when entering the above-mentioned current automatic control period, and acquires the current environmental temperature of the above-mentioned target area to obtain a first environmental temperature;

[0044] In step S1032, a second acquisition step clears the timing time when the timing time reaches the above-mentioned first predetermined time, and acquires the current environmental temperature of the above-mentioned target area to obtain a second environmental temperature;

[0045] In step S1033, in the case that the manual adjustment operation does not exist in the current automatic control period, the difference between the above-mentioned second environmental temperature and the above-mentioned first environmental temperature is calculated to obtain the above-mentioned environmental temperature change amount, the opening degree of the above-mentioned air outlet of the above-mentioned target area is adjusted according to the above-mentioned environmental temperature change amount to reduce the change of the above-mentioned environmental temperature, and the next above-mentioned automatic control period is entered;

[0046] Step S1034, the above-mentioned first acquisition step, the above-mentioned second acquisition step and the above-mentioned control step are repeated in turn until the above-mentioned manual adjustment operation exists in the above-mentioned current automatic control period, and the above-mentioned automatic control mode is exited.

[0047] In the above-mentioned embodiments, as shown in Figure 2 the automatic control mode is entered, a first predetermined time is set as an automatic control period, at the beginning of the automatic control period, an internal timer is started to work synchronously, and the current environment temperature of the target area is acquired to obtain a first environment temperature T2, after the first predetermined time is reached, the automatic control period is ended, the internal timer is reset, and the current environment temperature of the target area is acquired to obtain a second environment temperature T3, the difference between the second environment temperature T3 and the first environment temperature T2 is calculated to obtain an environment temperature change amount, the opening degree of the air outlet of the target area is adjusted according to the environment temperature change amount to reduce the change of the environment temperature, so that the target area is kept in the human comfortable temperature interval, and then the next automatic control period is entered, and the above-mentioned control mode is repeated to ensure that the target area is kept in the human comfortable temperature interval.

[0048] In order to ensure that the target area is kept in the human comfortable temperature interval, in an optional embodiment, the value of the above-mentioned first predetermined time ranges from 10s to 20s.

[0049] In the above-mentioned embodiments, the first predetermined time is set to be between 10s and 20s, so as to ensure that the control frequency is appropriate, the target area is kept in the human comfortable temperature interval, the fluctuation is avoided to be too large due to too frequent control, and the comfort is avoided to be affected due to too long control delay, and preferably, the above-mentioned first predetermined time is 10s.

[0050] In order to further ensure the user experience, in an optional embodiment, after step S103, the above-mentioned method further comprises:

[0051] Step S301, the above-mentioned automatic control mode is not entered within a second predetermined time, and the above-mentioned second predetermined time is greater than the above-mentioned first predetermined time.

[0052] In the above-mentioned embodiments, since the manual adjustment operation is detected, the automatic control mode is exited, that is, the opening degree of the air outlet of the air conditioner is manually controlled, the manual control is ensured to be prior, the automatic control mode is not entered within the second predetermined time, the manual control is avoided to be invalid due to the re-entry of the automatic control mode, and the user experience is affected, after the second predetermined time of exiting the automatic control mode, the restriction of not entering the automatic control mode is released, the manual control can be re-entered, and the unreasonable distribution of cold or heat due to no one control is avoided. In addition, the temperature sensor for detecting the environment temperature can stop working for the second predetermined time, and the energy consumption is reduced.

[0053] To further ensure the user experience, in an optional embodiment, the second predetermined time is in the range of 200s to 300s.

[0054] In the above embodiment, the second predetermined time is set between 200s and 300s, i.e. the automatic control mode interruption time is set between 200s and 300s, to avoid quickly entering the automatic control mode after manual operation, to preferentially ensure the manual control effect, and to avoid no one controlling the opening degree of the air outlet for a long time, affecting the comfort, and preferably, the second predetermined time is 300s.

[0055] In the above air outlet opening degree control method, first, in the case that the difference between the current environment temperature and the target temperature is in a predetermined range and the change rate of the environment temperature of the target region is greater than a predetermined change rate, the automatic control mode is entered, and the target region is any one of the regions; then, the automatic adjustment step, in the case that there is no manual adjustment operation in the current automatic control period, the opening degree of the air outlet of the target region is adjusted according to the environment temperature change amount to reduce the change of the environment temperature, the current automatic control period is the current automatic control period, the automatic control period is a period with a length of a first predetermined time after entering the automatic control mode, the automatic control period is continuous, the manual adjustment operation is an operation of manually adjusting the opening degree of the air outlet of the target region, and the environment temperature change amount is the difference between the environment temperature of the target region at the end of the current automatic control period and the environment temperature of the target region at the beginning of the current automatic control period; finally, the automatic adjustment step is repeated until there is the manual adjustment operation in the current automatic control period, and the automatic control mode is exited. This method enters the automatic control mode when the environment temperature of the target region changes rapidly, periodically detects the change trend of the environment temperature, adjusts the opening degree of the air outlet of the target region to alleviate the change of the temperature, and all of this makes the target region in the best temperature state until the manual adjustment operation is detected and the automatic control mode is exited, and all regions adjust the opening degree of the air outlet in the above manner to ensure that the cold or heat distribution of each region is reasonable, to meet the needs of all regions as much as possible, to ensure the comfort of the user, and to solve the problem of poor comfort experience caused by unreasonable cold or heat distribution of the air conditioner in the prior art.

[0056] It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0057] This application also provides a control device for the opening degree of an air conditioner vent. It should be noted that the control device for the opening degree of an air conditioner vent in this application can be used to execute the control method for the opening degree of an air conditioner vent provided in this application. The following describes the control device for the opening degree of an air conditioner vent provided in this application. The space where the air conditioner is located includes multiple areas, and each of the above areas includes the air conditioner vent.

[0058] Figure 3 This is a schematic diagram of a control device for the opening of an air conditioning vent according to an embodiment of this application. Figure 3 As shown, the device includes:

[0059] The first control unit 10 is used to enter an automatic control mode when the difference between the current ambient temperature and the target temperature is within a predetermined range and the rate of change of the ambient temperature in the target area is greater than a predetermined rate of change. The target area can be any one of the aforementioned areas.

[0060] To ensure that the target area remains within the human body's comfortable temperature range, in one optional embodiment, the device further includes:

[0061] The acquisition unit is used to acquire the ambient temperature of the target area once at a third predetermined time interval before entering the automatic control mode, and calculate the difference between the current ambient temperature and the previous ambient temperature to obtain the rate of change of the ambient temperature of the target area.

[0062] In the above embodiments, such as Figure 2 As shown, the system monitors changes in ambient temperature by periodically acquiring the ambient temperature of the target area and calculating the difference between the current ambient temperature T1 and the previous ambient temperature T0. This gives the rate of change of the ambient temperature in the target area. If the temperature change is too rapid, the ambient temperature in the target area may not remain within the human comfort range. Therefore, the system monitors the ambient temperature of the target area and, if the temperature change is too rapid, enters an automatic control mode to ensure that the ambient temperature in the target area remains within the human comfort range.

[0063] The second control unit 20 is configured to automatically adjust the opening degree of the air outlet of the target area according to the environmental temperature variation in the absence of a manual adjustment operation in a current automatic control period, so as to reduce the variation of the environmental temperature, the current automatic control period being the current automatic control period, the automatic control period being a period of time with a first predetermined time after the air conditioner enters the automatic control mode, the automatic control period being continuous, the manual adjustment operation being an operation of manually adjusting the opening degree of the air outlet of the target area, and the environmental temperature variation being a difference between the environmental temperature of the target area at the end of the current automatic control period and the environmental temperature of the target area at the beginning of the current automatic control period.

[0064] The air conditioner is controlled in the automatic control mode to adjust the opening degree of the air outlet, which is suitable for the cooling mode. In order to ensure that the cooling capacity of the air conditioner is reasonably distributed, in an optional embodiment, the second control unit comprises:

[0065] The first control module is configured to increase the opening degree of the air outlet of the target area when the air conditioner is in the cooling mode and the environmental temperature variation is greater than 0.

[0066] The second control module is configured to decrease the opening degree of the air outlet of the target area when the air conditioner is in the cooling mode and the environmental temperature variation is less than 0.

[0067] The third control module is configured to maintain the current opening degree of the air outlet of the target area when the air conditioner is in the cooling mode and the environmental temperature variation is equal to 0.

[0068] In the above embodiment, as Figure 2As shown, in the cooling mode, if the environmental temperature change amount is greater than 0, i.e., the environmental temperature T3 of the target area at the end of the current automatic control period is greater than the environmental temperature T2 of the target area at the beginning of the current automatic control period, it indicates that the internal environmental temperature of the target area in the current automatic control period has risen, and the opening degree of the air outlet of the target area is increased to reduce the temperature. If the environmental temperature change amount is less than 0, i.e., the environmental temperature T3 of the target area at the end of the current automatic control period is less than the environmental temperature T2 of the target area at the beginning of the current automatic control period, it indicates that the internal environmental temperature of the target area in the current automatic control period has fallen, and the opening degree of the air outlet of the target area is reduced to increase the temperature. If the environmental temperature change amount is equal to 0, i.e., the environmental temperature T3 of the target area at the end of the current automatic control period is equal to the environmental temperature T2 of the target area at the beginning of the current automatic control period, it indicates that the internal environmental temperature of the target area in the current automatic control period has not changed, and the current opening degree of the air outlet of the target area is maintained. All the areas are controlled in the above-mentioned manner to control the opening degree of the air outlet, which can avoid the situation that some areas have too much cold and the people feel too cold, and the situation that some areas have too little cold and the people feel too hot, ensures that the air conditioning cooling capacity is reasonably distributed, keeps the target area in the human comfortable temperature interval, and improves the comfort of the people.

[0069] The automatic control mode for controlling the opening degree of the air outlet of the air conditioner is also applicable to the heating mode. In order to ensure that the air conditioning heating capacity is reasonably distributed, in an optional embodiment, the second control unit includes:

[0070] A fourth control module is configured to, in the case that the air conditioner is in the heating mode and the environmental temperature change amount is greater than 0, reduce the opening degree of the air outlet of the target area.

[0071] A fifth control module is configured to, in the case that the air conditioner is in the heating mode and the environmental temperature change amount is less than 0, increase the opening degree of the air outlet of the target area.

[0072] A sixth control module is configured to, in the case that the air conditioner is in the heating mode and the environmental temperature change amount is equal to 0, maintain the current opening degree of the air outlet of the target area.

[0073] In the above embodiment, in the heating mode, if the environment temperature change amount is greater than 0, i.e., the environment temperature of the target area at the end of the current automatic control period is greater than the environment temperature of the target area at the beginning of the current automatic control period, it indicates that the internal environment temperature of the target area in the current automatic control period has risen, and the opening degree of the air outlet of the target area is reduced to reduce the temperature. If the environment temperature change amount is less than 0, i.e., the environment temperature of the target area at the end of the current automatic control period is less than the environment temperature of the target area at the beginning of the current automatic control period, it indicates that the internal environment temperature of the target area in the current automatic control period has fallen, and the opening degree of the air outlet of the target area is increased to increase the temperature.
