Technical Field

[0002] The parking air conditioner in a vehicle is powered by a storage battery. To ensure and extend the continuous operation of the parking air conditioner, a power generation mechanism, such as a generator, is installed in the vehicle to supply power to the storage battery.

[0051] 100. Air conditioner; 101. Processor; 102. Memory. Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0053] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0054] An exemplary embodiment of the present invention provides a parking air conditioner that can be installed in a vehicle for use by the occupants inside the vehicle. The vehicle may include, but is not limited to, logistics vehicles, trucks, RVs, etc.

[0055] A parking air conditioner can be an electrically driven air conditioner installed in the driver's cab of a vehicle, and it can operate without the vehicle's engine being started. Parking air conditioners can include, but are not limited to, roof-mounted parking air conditioners and built-in parking air conditioners.

[0056] The parking air conditioner includes a power supply unit and a power generation unit. The power supply unit supplies power to the parking air conditioner to ensure its operation. The power supply unit may include a battery, which may include, but is not limited to, lead-acid batteries, lithium batteries, graphene batteries, etc.

[0057] The power generation unit is used to supplement the power supply unit's power. That is, when the power generation unit is operating, the electricity it generates can charge the power supply unit, thereby supplementing its power. The power generation unit may include, but is not limited to, generators, or it may include a solar power generation device, such as photovoltaic solar panels. The generator or solar power generation device is configured to charge the power supply unit.

[0058] like Figure 1 As shown, an exemplary embodiment of the present invention provides a method for controlling a parking air conditioner, the method comprising the following steps:

[0059] Step S100: Confirm the communication status between the parking air conditioner and the generator unit. The communication status includes offline status.

[0060] Step S200: When the parking air conditioner and the power generation unit are offline, acquire the first detection data of the parking air conditioner and the second detection data of the power supply unit.

[0061] Step S300: Control the operating status of the parking air conditioner based on the relationship between the first detection data and the preset threshold, and the second detection data.

[0062] In step S100, the communication status includes an offline status, which indicates that the parking air conditioner and the generator unit cannot connect via communication at the current moment. Specifically, it can mean that the control system in the parking air conditioner and the generator unit are offline. It should be noted that the communication status can also include an online status, which indicates that the parking air conditioner and the generator unit are currently communicating.

[0063] In step S200, after confirming that the parking air conditioner and the power generation unit are offline, first detection data of the parking air conditioner and second detection data of the power supply unit are acquired. The first detection data of the parking air conditioner may include, but is not limited to, the instantaneous current during operation of the parking air conditioner. The second detection data of the power supply unit may include, but is not limited to, the detected voltage value of the power supply unit.

[0064] In step S300, after acquiring the first detection data and the second detection data, the first detection data is compared with a preset threshold, and the operating status of the parking air conditioner is flexibly controlled based on the comparison result and the second detection data.

[0065] The following example illustrates the use of the first detection data being the instantaneous current during the operation of the parking air conditioner and the second detection data being the detection voltage value of the power supply unit.

[0066] When the instantaneous current is less than a preset threshold, and the detected voltage value of the power supply unit decreases slightly or increases slightly within a predetermined time, it indicates that the generator unit is in operation, i.e., charging the power supply unit. Then, when the detected voltage value exceeds a set voltage value, a first operation is performed on the parking air conditioner. This first operation may include, but is not limited to, reducing the speed of the generator unit and / or reducing the speed of the compressor in the parking air conditioner. After running for a certain period, the parking air conditioner is then turned off to ensure that the voltage value of the power supply unit does not suddenly increase. This prevents the voltage value of the power supply unit from rising due to the sudden shutdown of the parking air conditioner, which could affect its operation and effectively ensure the reliable operation of the parking air conditioner.

[0067] When the instantaneous current exceeds a preset threshold, and the detected voltage value of the power supply unit shows a small decrease or an increase within a predetermined time, it indicates that the power generation unit is in operation. Then, when the detected voltage value exceeds a set voltage value, a second operation is performed on the parking air conditioner's operating status. This second operation may include, but is not limited to, reducing the speed of the power generation unit and / or reducing the speed of the compressor in the parking air conditioner. It should be noted that reducing the compressor speed in this second operation can be achieved by first reducing the compressor speed to a specified speed, running at that speed for a period of time, then further reducing the specified speed and running it for a period of time before turning off the parking air conditioner. This ensures that the voltage value of the power supply unit does not suddenly increase, preventing a sudden increase in the voltage value of the power supply unit due to the sudden shutdown of the parking air conditioner, which could affect the operation of the parking air conditioner and effectively guarantee the reliable operation of the parking air conditioner.

[0068] The preset threshold can be set manually, or it can be determined and stored in the parking air conditioner (e.g., in the air conditioner controller) based on multiple environmental test data or empirical values ​​when the vehicle leaves the factory. Furthermore, the specified speed, running time, etc., in the above examples can all be determined based on empirical values ​​or multiple test data, and are not specifically limited here.

[0069] In this embodiment, when the parking air conditioner and the generator unit are offline, the parking air conditioner can automatically identify the working status of the generator unit based on the real-time current of the parking air conditioner during operation and the detected voltage value of the power supply unit. This allows the parking air conditioner to make logical judgments and control over its operating status, preventing the voltage of the power supply unit from rising due to sudden shutdown of the parking air conditioner and affecting its operation. This effectively ensures the use of the parking air conditioner and improves its reliability and sustainable operating cycle.

[0070] like Figure 2As shown, taking a preset threshold as the current value and the first detection data as the instantaneous current as an example, where the instantaneous current is the instantaneous current value at the moment the parking air conditioner is running. In some embodiments, the preset threshold includes a first preset threshold P1 and a second preset threshold P2. The first preset threshold P1 is less than the second preset threshold P2.

[0071] In one example, the first preset threshold P1 may include, but is not limited to, 10A, and the second preset threshold P2 may include, but is not limited to, 25A.

[0072] Step S300: The step of controlling the operating status of the parking air conditioner based on the relationship between the first detection data and the preset threshold, and the second detection data, includes the following operations:

[0073] When the first detection data (instantaneous current I) is less than the first preset threshold P1, that is, when I < P1, the operating status of the parking air conditioner is processed based on the second detection data (i.e. the detection voltage value of the power supply unit).

[0074] When the first detection data (instantaneous current I) is greater than or equal to the first preset threshold P1 and less than or equal to the second preset threshold P2, i.e., P1≤I≤P2, the operating status of the parking air conditioner is processed based on the second detection data (i.e. the detection voltage value of the power supply unit).

[0075] When the first detection data (instantaneous current I) is greater than the second preset threshold P2, that is, when P2 < I, the operating status of the parking air conditioner is processed based on the second detection data (i.e. the detection voltage value of the power supply unit).

[0076] In this embodiment, the operating status of the parking air conditioner can be logically controlled based on the relationship between the current value of the parking air conditioner during operation and the preset threshold, combined with the detection voltage value of the power supply unit. This effectively prevents the operation of the parking air conditioner from being affected by the voltage increase of the power supply unit caused by the sudden shutdown of the parking air conditioner, thereby improving the reliability of the parking air conditioner operation.

[0077] like Figure 3 As shown, in some embodiments, the parking air conditioner includes a compressor, and the second detection data may include, but is not limited to, the detection voltage value V of the power supply unit. 电 .

[0078] When the first detection data (instantaneous current I) is less than the first preset threshold P1, that is, when I < P1, the detection voltage value V based on the power supply unit is... 电 The initial treatment process for the parking air conditioner includes the following methods:

[0079] First, determine that the power generation unit is in an operational state. Operational state indicates that the power generation unit is charging the power supply unit.

[0080] In one example, the process of determining whether the power generation unit is in a working state is as follows: The system continuously monitors for a first set time. If the voltage drop of the power supply unit detected within the first set time is less than a first value, or if the voltage of the power supply unit increases, then the power generation unit is determined to be in a working state. The first value may include, but is not limited to, 0.1V, and the first set time may include, but is not limited to, 30 minutes. The first set time may also be other values ​​in minutes.

[0081] Then, after confirming that the power generation unit is in working condition, the detected voltage value V of the power supply unit is obtained. 电 The detected voltage V of the power supply unit can be obtained through an on-board charging adapter with a voltage display function. 电 Alternatively, the voltage value V of the power supply unit can be measured using a battery tester.

[0082] When the detected voltage value V 电 When the voltage exceeds a predetermined value, the generator unit's speed is reduced, and the parking air conditioner is shut down according to a predetermined rule after receiving a shutdown command. The predetermined value may include, but is not limited to, 25V, and the predetermined rule may be to shut down the parking air conditioner according to its factory default settings.

[0083] In other words, taking the generator unit as an example, when the detected voltage value V... 电 When the voltage is greater than 25V, reduce the speed of the generator unit and turn off the air conditioner according to the factory default state after the parking air conditioner receives the shutdown command.

[0084] When the detected voltage value V 电 If the value is less than the predetermined value, and after the parking air conditioner receives the shutdown command, it first reduces the compressor speed to the first speed H1, and then shuts off the compressor after the compressor runs at the first speed H1 for a first time G1 seconds.

[0085] In this example, when the power generation unit is in operation and the first detection data is less than the first preset threshold P1, the operating status of the parking air conditioner is logically controlled according to the relationship between the second detection data and the predetermined value. This enables the power generation unit to reduce its speed after the parking air conditioner receives a shutdown command, thereby ensuring that the power supply unit will not affect the parking air conditioner due to sudden changes in voltage value, effectively improving the reliability of the parking air conditioner's operation.

[0086] like Figure 3 As shown, in some embodiments, the parking air conditioner includes a compressor, and the second detection data may include, but is not limited to, the detection voltage value V of the power supply unit. 电 .

[0087] When the first detected data (instantaneous current I) is greater than or equal to the first preset threshold P1 and less than or equal to the second preset threshold P2, that is, when P1≤I≤P2, the detection voltage value V based on the power supply unit is... 电 The process of performing a second treatment on the parking air conditioner includes the following methods:

[0088] First, confirm that the power generation unit is in working order.

[0089] In one example, the process of determining whether the power generation unit is in a working state is as follows: The system continuously monitors a second set time. If the voltage drop of the power supply unit detected within the second set time is less than a second value, or if the voltage of the power supply unit increases, then the power generation unit is determined to be in a working state. The second value may include, but is not limited to, 0.2V, and the second set time may include, but is not limited to, 20 minutes. The second set time may also be other values ​​in minutes.

[0090] Then, after confirming that the power generation unit is in working condition, the detected voltage value V of the power supply unit is obtained. 电 Among them, the detection voltage value V 电 The acquisition process is described in the above embodiments and will not be repeated here.

[0091] When the detected voltage value V 电 When the voltage exceeds a predetermined value, the generator unit's speed is reduced, and the parking air conditioner is shut down according to a predetermined rule after receiving a shutdown command. The predetermined value may include, but is not limited to, 25V, and the predetermined rule may be to shut down the parking air conditioner according to its factory default settings.

[0092] In other words, taking the generator unit as an example, when the detected voltage value V... 电 When the voltage is greater than 25V, reduce the speed of the generator unit and turn off the air conditioner according to the factory default state after the parking air conditioner receives the shutdown command.

[0093] When the detected voltage value V 电 If the value is less than the predetermined value, and after the parking air conditioner receives the shutdown command, the compressor speed is first reduced to the second speed H2, and after the compressor runs at the second speed H2 for a second time G2, the compressor speed is reduced from the second speed H2 to the first speed H1, and after the compressor runs at the first speed H1 for a first time G1 seconds, the compressor is then turned off.

[0094] In this example, when the power generation unit is in operation and the first detection data is greater than or equal to the first preset threshold P1 and less than or equal to the second preset threshold P2, the operating status of the parking air conditioner is logically controlled according to the relationship between the second detection data and the predetermined value. This enables the power generation unit to reduce its speed after the parking air conditioner receives a shutdown command, thereby ensuring that the power supply unit will not affect the parking air conditioner due to sudden changes in voltage value, effectively improving the reliability of the parking air conditioner's operation.

[0095] like Figure 3 As shown, in some embodiments, the parking air conditioner includes a compressor, and the second detection data may include, but is not limited to, the detection voltage value V of the power supply unit. 电 .

[0096] When the first detection data (instantaneous current I) is greater than the second preset threshold P1, that is, when P2 < I, the detection voltage value V based on the power supply unit is... 电 The process of performing third-party treatment on the parking air conditioner includes the following methods:

[0097] First, confirm that the power generation unit is in working order.

[0098] In one example, the process of determining whether the power generation unit is in operation is as follows: The system continuously monitors for a third set time. If the voltage drop of the power supply unit within the third set time is less than a third value, or if the voltage of the power supply unit increases, then the power generation unit is determined to be in operation. The third value may include, but is not limited to, 0.3V, and the third set time may include, but is not limited to, 15 minutes. The third set time may also be other values ​​in minutes.

[0099] Then, after confirming that the power generation unit is in working condition, the detected voltage value V of the power supply unit is obtained. 电 Among them, the detection voltage value V 电 The acquisition process is described in the above embodiments and will not be repeated here.

[0100] When the detected voltage value V 电 When the voltage exceeds a predetermined value, the generator unit's speed is reduced, and the parking air conditioner is shut down according to a predetermined rule after receiving a shutdown command. The predetermined value may include, but is not limited to, 25V, and the predetermined rule may be to shut down the parking air conditioner according to its factory default settings.

[0101] In other words, taking the generator unit as an example, when the detected voltage value V... 电 When the voltage is greater than 25V, reduce the speed of the generator unit and turn off the air conditioner according to the factory default state after the parking air conditioner receives the shutdown command.

[0102] When the detected voltage value V电 If the value is less than the predetermined value, and after the parking air conditioner receives the shutdown command, the compressor speed is first reduced to the third speed H3, and after the compressor runs at the third speed H3 for a third time G3, the compressor speed is reduced from the third speed H3 to the second speed H2. After the compressor runs at the second speed H2 for a second time G2, the compressor speed is reduced from the second speed H2 to the first speed H1, and after the compressor runs at the first speed H1 for a first time G1 seconds, the compressor is shut off.

[0103] In this example, when the power generation unit is in operation and the first detection data is greater than or equal to the second preset threshold P2, the operating status of the parking air conditioner is logically controlled according to the relationship between the second detection data and the predetermined value. This enables the power generation unit to reduce its speed after the parking air conditioner receives a shutdown command, thereby ensuring that the power supply unit will not affect the parking air conditioner due to sudden changes in voltage value, effectively improving the reliability of the parking air conditioner's operation.

[0104] It should be noted that the first time G1, the second time G2, and the third time G3 in the above examples can all be determined based on multiple experimental data or empirical values, and the specific values ​​of the first time G1, the second time G2, and the third time G3 are not specifically limited here.

[0105] Similarly, the third speed H3, the second speed H2, and the first speed H1 can all be determined based on multiple experimental data or empirical values, and the specific values ​​of the third speed H3, the second speed H2, and the first speed H1 are not specifically limited here.

[0106] like Figure 2 As shown, in some embodiments, the communication status also includes an online status, that is, the parking air conditioner and the power generation unit are in a communication connection state.

[0107] The method for controlling the parking air conditioner also includes the following steps:

[0108] When the parking air conditioner and the generator unit are online, and after the parking air conditioner receives a shutdown command, the generator unit's speed is reduced to a low-speed generator mode. It should be noted that the low-speed generator mode can be any existing generator mode, which will not be elaborated upon here.

[0109] After the generator unit operates in low-speed generator mode, turn off the parking air conditioner.

[0110] After the parking air conditioner is turned off, the generator unit starts and performs fast or slow charging on the power supply unit according to the voltage value of the power supply unit.

[0111] In this step, after the power generation unit starts up, when the detected voltage value of the power supply unit is less than a preset percentage of the voltage value of the power supply unit when it is fully charged, the power supply unit is rapidly charged. The preset percentage can be between 75% and 85%, or any other value.

[0112] After the power generation unit is started, when the detected voltage value of the power supply unit is greater than or equal to a preset ratio of the voltage value of the power supply unit when it is fully charged, the power supply unit is slow-charged.

[0113] In this step, when the parking air conditioner and the generator unit are online, after the parking air conditioner receives the shutdown command, it first reduces the speed of the generator unit to a low-speed generator mode. Then, after the parking air conditioner is turned off, the generator unit charges the power supply unit according to the voltage value of the power supply unit. This effectively ensures that the power supply unit will not be affected by sudden changes in voltage value, thus effectively improving the reliability and continuous operation cycle of the parking air conditioner.

[0114] like Figure 4 As shown, an example embodiment of the present invention provides an air conditioner 100. The air conditioner 100 includes a processor 101 and a memory 102 connected to the processor 101. The memory 102 stores computer-executable instructions. These computer-executable instructions can be invoked by the processor 101 to execute the parking air conditioner control method described in the above embodiment.

[0115] In the above scheme, the communication status between the parking air conditioner and the generator unit is first determined. When the parking air conditioner and the generator unit are offline, the parking air conditioner can automatically identify the working status of the generator unit based on the real-time current of the parking air conditioner and the detected voltage value of the power supply unit. This allows the parking air conditioner to make logical judgments and control the operating status of the parking air conditioner, preventing the voltage of the power supply unit from rising due to the sudden shutdown of the parking air conditioner and affecting its operation. This effectively ensures the use of the parking air conditioner and improves its reliability and sustainable operating cycle.

[0116] On the other hand, when the parking air conditioner and the generator unit are in communication, after the parking air conditioner receives the shutdown command, it first reduces the speed of the generator unit to a low-speed generator mode. Then, after the parking air conditioner is turned off, the generator unit charges the power supply unit according to the voltage value of the power supply unit. This effectively ensures that the power supply unit will not be affected by sudden changes in voltage value, thus effectively improving the reliability and sustainable operation cycle of the parking air conditioner.

[0117] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
