[0023] This embodiment first provides a control method of an air conditioner on a train, which can automatically adjust the corresponding air conditioner according to the number of passengers in different sub-regions of the train carriage, effectively improving the degree of intelligence. Figure 1 is a schematic diagram of a control method of an air conditioner on a train according to an embodiment of the present invention. As Figure 1 shown, the control method of the air conditioner on the train may include the following steps:

[0024] Step S102: Receive the trigger signal for the train to start air supply;

[0025] Step S104: Use radar to detect the number of passengers in different sub - regions of each carriage;

[0026] Step S106: Determine the operating parameters of the corresponding air conditioner according to the number of passengers in each sub - region;

[0027] Step S108: Control each air conditioner to work according to the determined operating parameters.

[0028] It should be noted that the methods in this embodiment and the following embodiments are all described from the perspective of the control device of the air conditioner on the train, that is, the control device executes the relevant steps. Through this control device, signals sent by the air conditioner can be received, and signals can be sent to the air conditioner. This control device can be set independently or can be set inside the air conditioner. The air conditioner in this embodiment has the characteristic of intelligence. It is precisely because as mentioned above, it can both send signals to the control device and receive signals sent by the control device. Specifically, it can be achieved by setting a controller on the air conditioner.

[0029] The train in this embodiment is provided with multiple carriages. The seat distribution in each carriage is divided into a preset number of sub - regions, and air conditioners corresponding to the sub - regions one by one are provided. There is a radar on the air conditioner. That is to say, when the seats in each carriage are divided into multiple sub - regions, multiple air conditioners can be correspondingly set in each carriage. The air conditioners on the train can actually refer to the indoor units of the air conditioners, which are small in volume and can meet the condition of having multiple units in a single carriage. In a preferred embodiment, the train can be a high - speed train.

[0030] Moreover, each air conditioner can be provided with a heat exchanger and a blower fan, so as to enable separate control of each air conditioner, such as separately adjusting the air supply speed and set temperature of a certain air conditioner. Since the multiple sub - regions in each carriage and the multiple air conditioners are set in one - to - one correspondence, while realizing separate control of each air conditioner, the temperature and air flow conditions of the sub - regions corresponding to each air conditioner can be separately adjusted.

[0031] In the above steps, step S102 receives the trigger signal for the train to start air supply. After the train starts air supply, a trigger signal can be sent to the control device for the control device to receive. It should be noted that when the train starts air supply, it can be considered for all the air conditioners in all the carriages on the train. Step S104 uses radar to detect the number of passengers in different sub - regions of each carriage. Since the sub - regions in each carriage are correspondingly provided with air conditioners and there is a radar on the air conditioner, the number of passengers in the corresponding sub - regions can be detected by the radar of each air conditioner.

[0032] Radar is a transliteration of the English word Radar, which is derived from the abbreviation of radio detection and ranging, meaning "radio detection and ranging". Radar can use radio methods to detect targets and determine their spatial positions. Therefore, radar can also be called "radio positioning". As an electronic device that uses electromagnetic waves to detect targets, radar can emit electromagnetic waves to irradiate targets and receive their echoes, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance (radial velocity), azimuth, and altitude.

[0033] In this embodiment, a radar is used to detect the number of passengers in each sub-region of the carriage to determine the specific number of passengers in each sub-region. In some other embodiments, in addition to the radar, other human sensing devices can also be used to detect the number of passengers in each sub-region of the carriage, such as infrared sensors. Similarly, infrared sensors can also be installed on the air conditioner to accurately determine the number of passengers in the sub-region corresponding to each air conditioner.

[0034] Step S106 determines the operating parameters of the corresponding air conditioner according to the number of passengers in each sub-region. In a specific embodiment, the operating parameters of the air conditioner can include the air supply wind speed and the set temperature. Step S108 controls each air conditioner to work according to the determined operating parameters. Specifically, after determining the corresponding air supply wind speed and set temperature of each air conditioner, each air conditioner can be controlled to work according to the determined air supply wind speed and set temperature, so that the working state of each air conditioner conforms to the actual situation of the corresponding sub-region.

[0035] If the number of passengers in a sub-region is larger, it means the passengers are more crowded, the air circulation is worse, and the passengers in this sub-region are more likely to feel hot and stuffy. Therefore, the air supply wind speed can be set larger and the set temperature can be set lower. If the number of passengers in a sub-region is smaller, it means the passengers are sparser, the air circulation is better, and the passengers in this sub-region are less likely to feel hot and stuffy. Therefore, the air supply wind speed can be set smaller and the set temperature can be set higher, thus effectively saving electric energy. And, in a specific embodiment, if the number of passengers in a certain sub-region is 0, the corresponding air conditioner can be controlled to turn off, which can also effectively save the electric energy of the air conditioner.

[0036] In a specific embodiment, the air supply wind speed of the air conditioner can be adjusted by the rotation speed of the air supply fan of the air conditioner. Therefore, controlling the air conditioner to work according to the determined air supply wind speed can be to control the air supply fan to work at the corresponding rotation speed. Generally, the larger the rotation speed of the air supply fan, the larger the air supply wind speed; the smaller the rotation speed of the air supply fan, the smaller the air supply wind speed. And controlling the air conditioner to work according to the determined set temperature can be achieved by adjusting the working state of the heat exchanger of the air conditioner.

[0037] In summary, the control method of the air conditioner on the train in this embodiment receives the trigger signal for the train to start blowing air, uses radar to detect the number of passengers in different sub - regions of each carriage, determines the operating parameters of the corresponding air conditioner according to the number of passengers in each sub - region, and controls each air conditioner to work according to the determined operating parameters. It can automatically adjust the corresponding air conditioner according to the number of passengers in different sub - regions of the train carriage, effectively improving the degree of intelligence.

[0038] In some alternative embodiments, higher technical effects can be achieved for the air conditioner on the train by further optimizing and configuring the above steps. The following details the control method of the air conditioner on the train in this embodiment in combination with the introduction of an alternative execution process of this embodiment. This embodiment is only an example of the execution process. In specific implementation, the execution order and operating conditions of some steps can be modified according to specific implementation requirements. Figure 2 FIG. is a detailed flowchart of the control method of the air conditioner on the train according to an embodiment of the present invention. The control method of the air conditioner on the train includes the following steps:

[0039] Step S202, receiving the trigger signal for the train to start blowing air;

[0040] Step S204, using radar to detect the number of passengers in different sub - regions of each carriage;

[0041] Step S206, determining whether the number of passengers in the sub - region is greater than or equal to the first preset number. If so, execute step S208; if not, execute step S212;

[0042] Step S208, determining that the air supply speed of the corresponding air conditioner is the first preset speed and the set temperature is the first preset temperature;

[0043] Step S210, controlling each air conditioner to work according to the determined air supply speed and set temperature;

[0044] Step S212, determining whether the number of passengers in the sub - region is greater than 0. If so, execute step S214; if not, execute step S216;

[0045] Step S214, for every second preset number reduction in the number of passengers compared to the first preset number, determining that the air supply speed of the corresponding air conditioner is reduced by the second preset speed and the set temperature is increased by the second preset temperature;

[0046] Step S216, when the number of passengers in the sub - region is 0, controlling the corresponding air conditioner to turn off.

[0047] In the above steps, after step S202 receives the trigger signal for the train to start air supply, step S204 and step S206 can be executed, using radar to detect the number of passengers in different sub-areas in each carriage, and judging whether the number of passengers in the sub-area is greater than or equal to the first preset number. And if the judgment result of step S206 is yes, that is, the number of passengers in the sub-area is greater than or equal to the first preset number, step S208 is executed to determine that the air supply wind speed of the corresponding air conditioner is the first preset wind speed, and the set temperature is the first preset temperature.

[0048] If the number of passengers in a sub-area is greater than or equal to the first preset number, it can be considered that the number of passengers in the sub-area is too large or even full, and the passengers in the sub-area are more likely to feel hot and stuffy, so the corresponding air supply speed of the air conditioner can be determined to be the first preset speed, and the set temperature can be the first preset temperature. The first preset wind speed can be a very high wind speed, or it can be considered to be the maximum wind speed that the air conditioner can reach. The first preset temperature can be a relatively low temperature within a reasonable temperature range when the air conditioner is running in cooling mode, for example, it can be 20°C. A higher air supply speed and a lower set temperature can significantly reduce the temperature of the sub-area, and the air circulation is smooth, so that the passengers in the sub-area feel cool and comfortable.

[0049] If the judgment result of step S206 is no, that is, the number of passengers in the sub-area is less than the first preset number, step S212 is executed to determine whether the number of passengers in the sub-area is greater than 0. If the judgment result of step S212 is yes, that is, the number of passengers in the sub-area is greater than 0, step S214 is executed, and the air supply wind speed of the corresponding air conditioner is determined to be the first preset wind speed lower than the second preset wind speed, and the set temperature is the first preset temperature higher than the second preset temperature for each decrease in the number of passengers compared to the first preset number by the second preset number. In other words, the prerequisite for executing step S214 is that the number of passengers in the sub-area is less than the first preset number and greater than 0.

[0050] If the number of passengers in the sub-area is less than the first preset number and greater than 0, it means that the passengers in the sub-area are definitely not full, but it also means that there are passengers in the sub-area and it is not vacant. Therefore, the air supply speed of the air conditioner can be appropriately reduced and the set temperature can be appropriately increased, so as to save electricity while meeting the comfort of the passengers in the sub-area. Specifically, for every decrease in the number of passengers by a second preset number compared to the first preset number, the corresponding air supply speed of the air conditioner is determined to be the first preset speed lower than the second preset speed, and the set temperature is the first preset temperature higher than the second preset temperature.

[0051] The following introduces a specific embodiment: If the first preset quantity is 10, the second preset quantity is 2, the first preset wind speed is A, the second preset wind speed is B, the first preset temperature is 20°C, and the second preset temperature is 2°C. Then, when the number of passengers in a certain sub-region is 8, the corresponding air supply wind speed of the air conditioner can be A - B, and the set temperature can be 22°C. The specific values of the above preset parameters are only examples and do not limit the present invention. In some other embodiments, they can also be set to other values according to the actual situation.

[0052] It should be noted that if the reduced value of the number of passengers compared to the first preset quantity is not an integer multiple of the second preset quantity, then the air supply wind speed and the set temperature can be determined according to the quotient obtained by dividing the reduced value by the second preset quantity, that is, the remainder that cannot be divided evenly can be ignored. For example, if the number of passengers in a certain sub-region is 5, and the reduced value compared to the first preset quantity of 10 is 5, then the air supply wind speed and the set temperature can be determined according to the quotient 2 obtained by dividing the reduced value 5 by the second preset quantity 2. The determined air supply wind speed can be A - 2B, and the set temperature can be 24°C. Similarly, if the number of passengers in a certain sub-region is 3, and the reduced value compared to the first preset quantity of 10 is 7, then the air supply wind speed and the set temperature can be determined according to the quotient 3 obtained by dividing the reduced value 7 by the second preset quantity 2. The determined air supply wind speed can be A - 3B, and the set temperature can be 26°C.

[0053] After determining the air supply wind speed and the set temperature in step S208 and step S214, step S210 can be executed to control each air conditioner to work according to the determined air supply wind speed and set temperature. For example, if the number of passengers in a certain sub-region of a carriage is 10, then the determined air supply wind speed of the corresponding air conditioner is A, and the set temperature is 20°C, and the air conditioner corresponding to this sub-region can be controlled to work with an air supply wind speed of A and a set temperature of 20°C.

[0054] For another example, if the number of passengers in another sub-region of the carriage is 6, then the determined air supply wind speed of the corresponding air conditioner is A - 2B, and the set temperature is 24°C, and the air conditioner corresponding to this sub-region can be controlled to work with an air supply wind speed of A - 2B and a set temperature of 24°C. In short, it enables the air conditioners corresponding to different sub-regions in each carriage to be independently controlled, and the air supply wind speed and the set temperature can be adjusted without affecting each other, so that the working state of each air conditioner conforms to the actual situation of its corresponding sub-region, improving the comfort level of passengers in different sub-regions.

[0055] When the judgment result in step S212 is negative, since the number of passengers cannot be negative, it can be undoubtedly determined that the number of passengers is 0, that is, step S216 is executed, the number of passengers in the sub-region is 0, and the corresponding air conditioner is controlled to be turned off. The fact that the number of passengers in the sub-region is 0 indicates that there are no passengers in this sub-region and it is in a vacant state. For a sub-region without passengers, by timely controlling the corresponding air conditioner to be turned off, the electric energy of the air conditioner can be effectively saved. Controlling the air conditioner to be turned off can actually be controlling the heat exchanger and the air supply fan of the air conditioner to be turned off.

[0056] In a specific embodiment, each sub-outlet is provided for each air conditioner corresponding to the sub-region, and each sub-outlet is provided with a deflector. That is to say, there is a one-to-one correspondence between each sub-region, air conditioner, and sub-outlet in the carriage. After controlling the corresponding air conditioner to be turned off in step S216, it may further include: controlling the corresponding deflector to close the sub-outlet. For an air conditioner that is not necessary to be turned on, timely controlling the corresponding deflector to close the sub-outlet can prevent dust and other impurities in the carriage air from entering the interior of the air conditioner through the sub-outlet, affecting the cleanliness of components such as the heat exchanger and the air supply fan.

[0057] In addition, each sub-outlet may be provided with a horizontal swing blade and a vertical swing blade to adjust the air supply direction. Specifically, the horizontal swing blade can adjust the up-and-down air supply direction; the vertical swing blade can adjust the left-and-right air supply direction. That is to say, for each sub-region in the carriage, not only can the air supply speed and set temperature of the corresponding air conditioner be adjusted separately, but also the air supply direction of the corresponding sub-outlet can be adjusted separately.

[0058] In summary, for the control method of the air conditioner on the train in this embodiment, when the number of passengers in the sub-region is greater than or equal to the first preset number, the air supply speed of the corresponding air conditioner is determined to be the first preset speed, and the set temperature is the first preset temperature; when the number of passengers in the sub-region is less than the first preset number and greater than 0, for each reduction of the second preset number in the number of passengers in the sub-region compared to the first preset number, the air supply speed of the corresponding air conditioner is determined to be reduced by the second preset speed from the first preset speed, and the set temperature is increased by the second preset temperature from the first preset temperature; when the number of passengers in the sub-region is 0, the corresponding air conditioner is controlled to be turned off. The seats in the train carriage are refined into multiple sub-regions, and the air supply speed and set temperature of the corresponding air conditioner are adjusted according to the number of passengers in each sub-region, meeting the comfort requirements of passengers in different sub-regions.

For example, the air conditioner is provided with a dedicated control device 300 inside, and cooperates with the controller dedicated to executing component control.

[0062] The processor 310 may be a central processing unit (CPU) or a digital processing unit, etc. The processor 310 sends and receives data via a communication interface. The memory 320 is used to store programs executed by the processor 310. The memory 320 is any medium that can be used to carry or store desired program codes in the form of instructions or data structures and can be accessed by a computer, and may also be a combination of multiple memories 320. The above-mentioned control program 321 can be downloaded from a computer-readable storage medium to a corresponding computing / processing device or downloaded and installed to the control device 300 via a network (e.g., the Internet, a local area network, a wide area network, and / or a wireless network).

[0063] This embodiment also provides an air conditioner, which may have the control device 300 of the train air conditioner of the above embodiment. That is, the control device 300 may not be arranged outside the air conditioner, but may be arranged on the air conditioner. The control device 300 and the controller of the air conditioner itself may be the same component, that is, the control device 300 is used to control the operation of the air conditioner itself, and is also used to receive signals from other devices and send signals to other devices.

[0064] Alternatively, the control device 300 and the controller of the air conditioner itself can be different components. That is, the controller is used to control the operation of the air conditioner itself, and the control device 300 is used to receive signals from other devices and send signals to other devices. However, the control device 300 also communicates with the controller of the air conditioner to receive signals from the controller of the air conditioner itself and send signals to the controller.
