[0056] As people's living standards improve, the demand for refrigeration or heating equipment is gradually increasing. In refrigeration or heating equipment, the compressor is usually the core component. Due to limitations in compressor principles, materials, and processes, compressors typically have a certain start-stop lifespan, exceeding which will lead to compressor damage.

[0057] To address the aforementioned issues, relevant technologies primarily employ the following methods: setting fixed parameters such as minimum operating time, minimum downtime, or maximum number of runs per hour, and controlling the compressor's start and stop based on these parameters. Alternatively, setting a buffer zone at the critical refrigeration temperature to prevent frequent compressor starts when temperatures fluctuate near the critical temperature; or controlling the compressor directly through a temperature control algorithm at the application layer.

[0058] However, the methods in these technologies have certain drawbacks: They operate in a single mode, and when the maximum number of runs per hour is exceeded, the cooling mode is no longer controlled according to the response mechanism within that hour, potentially leading to significant fluctuations in cooling temperature. Furthermore, the intermittent control of ambient temperature makes it impossible to respond flexibly to varying cooling or heating demands. Overall, the compressor control and specific cooling logic are heavily coupled, resulting in a complex overall logic.

[0059] To address the aforementioned deficiencies, this application provides a compressor state control method. An electronic device with cooling and / or heating functions counts the cumulative number of compressor start-stop cycles, adjusts the start-stop duration parameter based on this count, and controls the compressor's start-stop based on the compressor's current state and the adjusted start-stop duration parameter. By adjusting the start-stop duration parameter according to the compressor's start-stop cycle, the start-stop duration parameter is dynamically adjusted and increased after each start-stop cycle. This allows the compressor to respond quickly when the cumulative number of start-stop cycles is low, and extends the duration of start-stop operations as the cumulative number of start-stop cycles increases, thus balancing compressor lifespan and extending its service life.

[0060] The following specific embodiments illustrate the application scenarios and implementation process of this application.

[0061] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an application scenario of the compressor state control method provided in this application embodiment. For example... Figure 1 As shown, the compressor can include two operating states: a first operating state and a second operating state. The first operating state can include: start-up, stop, running, and emergency stop. The second operating state can include: standby, locked standby, fault standby, locked stop, and fault stop. These operating states can transition between each other, triggered by events. Specifically, the stop state in the first operating state is a normal stop state excluding locked stop and fault stop. The standby state in the second operating state is a normal standby state excluding locked standby and fault standby.

[0062] In electronic devices with cooling and / or heating functions, such as air conditioners, refrigerators, and ice makers, to avoid frequent compressor start-stop cycles, start-stop duration parameters can be set to correspond to changes in the compressor's operating state. These parameters can include start-up duration and stop-down duration. The start-up duration parameter can include the minimum running time, and the stop-down duration parameter can include the minimum stop-down time. For example, when the compressor starts for the first time, the corresponding start-up duration and stop-down duration parameters can be the minimum values ​​of the minimum running time and the minimum stop-down time, respectively. In this case, the compressor's response speed is the fastest.

[0063] The current start-stop count corresponds to the start-up duration parameter, which is the minimum operating time the compressor needs to achieve. When a shutdown event is detected, the compressor transitions from its current state to a shutdown state. If the compressor's operating time from start-up to the current moment has already reached the minimum operating time, the compressor is controlled to stop immediately. The current start-stop count corresponds to the shutdown duration parameter, which is the minimum shutdown duration the compressor needs to achieve. When a start-up event is detected, the compressor transitions from its current state to a start-up state. If the compressor's shutdown time from stop-up to the current moment has already reached the minimum shutdown duration, the compressor is controlled to start immediately.

[0064] Accordingly, upon receiving a shutdown event trigger command, the compressor is controlled to enter a shutdown state, and the compressor's runtime is recorded. When the runtime reaches the shortest runtime corresponding to the current number of start-stop cycles, the compressor is controlled to stop. Upon receiving a start event trigger command, the compressor is controlled to enter a start state, and the compressor's shutdown time is recorded. When the shutdown time reaches the shortest shutdown time corresponding to the current number of start-stop cycles, the compressor is controlled to restart, thereby preventing frequent compressor start-stop cycles and protecting the compressor from damage.

[0065] For example, the start-up duration parameter and the shutdown duration parameter can be variable parameters. The electronic device can dynamically adjust them according to the cumulative number of start-ups and shutdowns of the compressor, so that the start-up duration parameter and the shutdown duration parameter increase with the increase of the cumulative number of start-ups and shutdowns. The closer the cumulative number of start-ups and shutdowns is to the lifespan, the longer the duration corresponding to the start-up duration parameter and the shutdown duration parameter, thereby ensuring that the equipment can respond quickly in the early stage when the number of uses is less, and at the same time extending the service life of the compressor.

[0066] The minimum running time and minimum stopping time for the first start-up and shutdown of the compressor can be set according to the total number of start-ups and shutdowns of the compressor.

[0067] In some embodiments, such as Figure 1 As shown, when the compressor is in a stopped state, the running time of the compressor from startup to the current moment is determined. When the running time reaches the startup time parameter corresponding to the current number of start-stop cycles, the compressor is controlled to stop running and a shutdown completion event is triggered. When the shutdown completion event is detected, the compressor is controlled to enter a standby state (i.e., the initial power-on state). In the standby state, when a startup event is detected, the compressor is controlled to enter the startup state.

[0068] Accordingly, when the compressor is in the start-up state, the shutdown duration from when the compressor stops running to the current moment is determined. When the shutdown duration reaches the shutdown duration parameter corresponding to the current number of start-stop cycles, the compressor is controlled to start. After the compressor starts, a start-up completion event is triggered, and the compressor is controlled to enter the running state. When a shutdown event is detected, the compressor is controlled to enter the shutdown state. When the running time from when the compressor starts to the current moment reaches the start-up duration parameter corresponding to the current number of start-stop cycles, the compressor is controlled to stop running.

[0069] Correspondingly, when the compressor is in start-up, stop-down, or running state, an emergency stop event can be triggered, and the compressor can enter an emergency stop state when the power supply to the compressor is detected to be cut off. When the power supply to the compressor is detected to be reconnected, an emergency stop completion event is triggered, and the compressor enters a normal standby state.

[0070] In some embodiments, such as Figure 1 As shown, when a shutdown event is detected, a shutdown control command is output to control the compressor to enter a normal shutdown state. The compressor can shut down when the runtime from startup to the current moment reaches the startup duration parameter corresponding to the current number of start-stop cycles. When the compressor detects an abnormal event, a shutdown control command is output to control the compressor to enter an abnormal shutdown state. The compressor can shut down when the runtime from startup to the current moment reaches the startup duration parameter corresponding to the current number of start-stop cycles. In the abnormal shutdown state, the compressor returns to a normal shutdown state in response to an abnormal recovery event.

[0071] The abnormal shutdown states include locked shutdown and fault shutdown; abnormal events include locked events and fault events; and abnormal recovery events include unlocking events and fault recovery events. When the compressor's tilt angle is detected to be greater than a preset tilt angle or the compressor is in a power switching state, a locked event is triggered, entering the locked shutdown state. The compressor can stop when the runtime from startup to the current moment reaches the startup duration parameter corresponding to the current number of start-stop cycles. In the locked shutdown state, when the compressor's tilt angle is detected to be less than a preset tilt angle or the compressor's power supply is stable, an unlocking event is triggered, entering the normal shutdown state. When the compressor stops completely, a shutdown completion event is triggered, entering the locked standby state.

[0072] When a compressor fault is detected, a fault event is triggered (e.g., compressor undervoltage, phase loss, or abnormal vibration), and the system enters a fault shutdown state. When the running time from startup to the current moment reaches the startup time parameter corresponding to the current number of start-stop cycles, the system can be shut down. In the fault shutdown state, when the compressor fault is detected to be resolved, a fault recovery event is triggered, and the system enters a normal shutdown state. When the compressor shutdown is completed, a shutdown completion event is triggered, and the system enters a fault standby state.

[0073] In some embodiments, such as Figure 1 As shown, when a shutdown completion event is detected in a normal shutdown state, the compressor is controlled to enter a normal standby state; when a shutdown completion event is detected in an abnormal shutdown state, the compressor is controlled to enter an abnormal standby state, and in the abnormal standby state, it enters a normal standby state in response to an abnormal recovery event.

[0074] Abnormal standby states include locked standby and fault standby. When the compressor is in normal standby mode, if the compressor's tilt angle is detected to be greater than a preset tilt angle or the compressor is in a power switching state, a locking event is triggered, and the compressor enters locked standby mode. In locked standby mode, if the compressor's tilt angle is less than a preset tilt angle or the compressor's power supply is stable, an unlocking event is triggered, and the compressor enters normal standby mode. When the compressor is in normal standby mode, if a compressor fault is detected, a fault event is triggered, and the compressor enters fault standby mode. In fault standby mode, if the compressor fault is detected to be resolved, a fault recovery event is triggered, and the compressor enters normal standby mode.

[0075] The specific process of implementing the compressor state control method is described below through embodiments of this application.

[0076] Please see Figure 2 , Figure 2 This is a schematic flowchart of a compressor state control method provided in an embodiment of this application. Figure 2 As shown, the method may include the following steps:

[0077] S201, obtain the cumulative number of compressor start-stops and start-stop duration parameters.

[0078] The start-stop duration parameters include start-up duration parameters and stop-down duration parameters.

[0079] In some embodiments, in electronic devices with cooling and / or heating functions such as air conditioners, refrigerators, and ice makers, to avoid frequent compressor starts, start-stop duration parameters can be set. These parameters can include a start-up duration parameter (i.e., the shortest running time corresponding to the current number of start-stop cycles) and a stop duration parameter (i.e., the shortest stop time corresponding to the current number of start-stop cycles). If the compressor receives a stop event trigger command and enters a stop state, it will only stop after the running time reaches the start-up duration parameter. If the compressor receives a start event trigger command and enters a start state, it will only start again after the stop duration reaches the stop duration parameter. This operation ensures that the compressor does not start and stop frequently, preventing compressor damage. In this embodiment, the start-up duration parameter and the stop duration parameter are variable parameters.

[0080] S202, adjust the start-stop duration parameter according to the cumulative number of start-stops so that the start-stop duration parameter increases with the increase of the cumulative number of start-stops.

[0081] In some embodiments, after obtaining the cumulative number of compressor start-stops, start-up duration parameters, and stop-down duration parameters, the start-up duration parameters and stop-down duration parameters can be corrected based on the cumulative number of start-stops. This ensures that the start-up duration parameters and stop-down duration parameters increase with the cumulative number of start-stops. The closer the cumulative number of start-stops is to the lifespan, the longer the time periods corresponding to the start-up duration parameters and stop-down duration parameters. This guarantees rapid response from the equipment in the early stages when usage is low. As usage gradually increases, the start-up duration parameters and stop-down duration parameters are gradually increased to reduce the number of start-stops within the same time period, thus extending the compressor's lifespan. When correcting the start-up duration parameters and stop-down duration parameters, a preset correction coefficient can be introduced. The specific correction process will be described in the embodiments described later.

[0082] It should be noted that compressors have good tolerance when the cumulative number of start-stop cycles is low, and can withstand a certain frequency of start-stop cycles. The start-up and stop-down durations are relatively short. This means that if the compressor can stop after a short run, it can quickly enter a stopped state when it receives a stop event trigger command; similarly, if it can restart after a short stop, it can quickly enter a starting state when it receives a start event trigger command. However, over time, the cumulative number of start-stop cycles gradually increases, and the compressor's tolerance gradually decreases. Frequent start-stop cycles will affect the compressor's lifespan. Therefore, as the cumulative number of start-stop cycles increases, the start-up and stop-down durations should be increased accordingly to prevent frequent start-stop cycles and thus extend the compressor's lifespan.

[0083] S203, obtain the current status of the compressor.

[0084] In some embodiments, when controlling the start and stop of the compressor, control is performed based on the current state of the compressor and the corrected start and stop duration parameters. Therefore, after obtaining the cumulative number of start and stop times and start and stop duration parameters of the compressor, and correcting the start and stop duration parameters based on the cumulative number of start and stop times, the current state of the compressor is also obtained, such as the compressor being in a start state, a stop state, or a running state.

[0085] In some embodiments, the compressor's start-up state or stop state can be taken as the current state. When the compressor receives a start-up event trigger command, the compressor is controlled to enter the start-up state; when the compressor receives a stop event trigger command, the compressor is controlled to enter the stop state.

[0086] S204 controls the start and stop of the compressor based on the corrected start / stop duration parameters and the current state.

[0087] In some embodiments, after correcting the start-up duration parameters and stop-down duration parameters and obtaining the current state of the compressor, the compressor's start-up or stop operation can be controlled according to the corrected start-up duration parameters, stop-down duration parameters, and the compressor's current state. If the current state is that the compressor enters the stop state when it receives a stop event trigger command, then the start-up duration can only reach the start-up duration parameter corresponding to the current number of start-stop cycles before stopping. If the current state is that the compressor enters the start state when it receives a start event trigger command, then the stop-down duration can only reach the stop-down duration parameter corresponding to the current number of start-stop cycles before restarting, thereby preventing the compressor from frequently starting and stopping and preventing compressor damage.

[0088] In this embodiment, an electronic device with cooling and / or heating functions counts the cumulative number of compressor start-stop cycles, adjusts the start-stop duration parameter based on this count, and controls the compressor's start-stop operation based on the compressor's current state and the adjusted start-stop duration parameter. By adjusting the start-stop duration parameter according to the compressor's start-stop cycle, the start-stop duration parameter is dynamically adjusted and increased after each start-stop cycle. This allows the compressor to respond quickly when the cumulative number of start-stop cycles is low, and extends the start-stop operation duration as the cumulative number of start-stop cycles increases, thus balancing the compressor's lifespan. This improves the user experience while maximizing the compressor's lifespan.

[0089] In step S202, the correction of the start-stop duration parameter based on the cumulative number of start-stops includes: calculating the product of the cumulative number of start-stops and the preset correction coefficient to obtain the correction value; and calculating the sum of the start-stop duration parameter and the correction value to obtain the corrected start-stop duration parameter.

[0090] In some embodiments, when correcting the start-stop duration parameter, it can be corrected based on the cumulative number of start-stops and by introducing a preset correction coefficient. The specific correction process is as follows: First, multiply the cumulative number of start-stops by the preset correction coefficient to obtain the correction value; second, add the start-stop duration parameter to the correction value to obtain the corrected start-stop duration parameter.

[0091] It should be noted that when calculating the sum of the start-stop duration parameter and the correction value, you can first set the minimum running time and minimum stopping time corresponding to the first start-stop, and then add the minimum running time or minimum stopping time to the correction value; alternatively, you can add the previously obtained start-stop duration parameter to the correction value to obtain the corrected start-stop duration parameter. When correcting the start-stop duration parameter, it should be continuously increased as the cumulative number of start-stops increases. However, the start-stop duration parameter cannot be increased without limit. An upper limit can be set, and once the upper limit is reached, the start-stop duration parameter cannot be increased further. If the start-stop duration parameter is increased without limit, it will lead to excessively long compressor start-up or shutdown times, affecting the user experience.

[0092] Accordingly, the preset correction coefficient can be a fixed value or a variable value, which can gradually increase with the increase of the cumulative number of start-stop cycles. Its value range is an integer or decimal greater than 0. Preferably, the preset correction coefficient can be set to a decimal greater than 0 and less than or equal to 1. The specific value can be determined according to the actual application scenario, and is not limited here.

[0093] For example, let t1 be the shortest runtime corresponding to the current number of start-stop cycles, t2 be the shortest shutdown duration corresponding to the current number of start-stop cycles, N be the cumulative number of compressor start-stop cycles, P1 and P2 be the correction coefficients, t1_base be the minimum shortest runtime corresponding to the first start-stop, t2_base be the minimum shortest shutdown duration corresponding to the first start-stop, t1_max be the maximum shortest runtime or start-up duration parameter corresponding to the total number of start-stop cycles, and t2_max be the maximum shortest shutdown duration or shutdown duration parameter corresponding to the total number of start-stop cycles. Then:

[0094] t1 = t1_base + N*P1 and t1 is less than or equal to t1_max;

[0095] t2 = t2_base + N*P2 and t2 is less than or equal to t2_max.

[0096] For example, suppose the minimum shortest running time t1_base corresponding to the first start-up and stop is 1 minute, the minimum shortest stop time t2_base corresponding to the first start-up and stop is 2 minutes, the correction coefficients P1 and P2 are 0.5 and 0.6 respectively. When the cumulative number of start-ups and stop-stops of the compressor (i.e. the current number of start-ups and stop-stops) is 10 times, the minimum running time t1 corresponding to the current number of start-ups and stop-stops is 1 + 10 × 0.5 = 6 minutes, and the minimum stop time t2 corresponding to the current number of start-ups and stop-stops is 2 + 10 × 0.6 = 8 minutes. That is, when the compressor receives the trigger command of the stop event, it enters the stop state and runs for at least 6 minutes before stopping. When the compressor receives the trigger command of the start event, it enters the start state and stops for at least 8 minutes before starting.

[0097] In step S204, the start / stop duration parameters include start duration parameters, such as... Figure 3 As shown, controlling the compressor's start-up and shutdown based on the corrected start-up / shutdown duration parameters and the current state may include the following steps:

[0098] S301, when the current state is a shutdown state, determine the running time of the compressor from startup to the current moment.

[0099] In some embodiments, the start-stop duration parameter includes a start-up duration parameter, which is the shortest runtime corresponding to the current number of start-stop cycles. Controlling the compressor's start-up and stop based on the corrected start-stop duration parameter and the current state can be as follows: controlling the compressor's stop based on the corrected start-up duration parameter and the current state. When the compressor's current state is stopped, controlling the compressor's stop first determines the runtime of the compressor from start-up to the current moment, and then controls the compressor to stop in subsequent steps.

[0100] S302, when the runtime is greater than or equal to the startup duration parameter, controls the compressor to stop running and triggers a shutdown completion event.

[0101] In some embodiments, when the compressor is currently in a stopped state, after determining the running time of the compressor from startup to the current moment, it can be determined whether the running time of the compressor is greater than or equal to the startup time parameter. When the running time is greater than or equal to the startup time parameter, the compressor is controlled to stop running (i.e., stop), and a stop completion event can be triggered at the same time. In subsequent steps, the compressor is controlled to enter a standby state.

[0102] For example, the compressor's runtime from startup to the current moment is 10 minutes, the startup duration parameter is 6 minutes, the compressor's runtime is greater than the startup duration parameter, the compressor is controlled to stop running and a shutdown completion event is triggered, and in subsequent steps the compressor is controlled to enter standby state.

[0103] In some embodiments, the shutdown completion event is an internal event of the compressor, which also includes a start completion event and an emergency stop completion event; shutdown is an external event of the compressor, which also includes events such as start, lock, unlock, fault, and fault recovery. External events are triggered by the application layer, and internal and external events are triggered when the compressor meets the event triggering conditions, thereby enabling control of the compressor to perform state transitions.

[0104] S303 controls the compressor to enter standby mode when a shutdown completion event is detected.

[0105] In some embodiments, a shutdown completion event is triggered when the compressor stops. When the shutdown completion event is detected, it indicates that the compressor has stopped and can be put into standby mode. At this time, the compressor can be controlled to enter standby mode, i.e., the initial power-on state, and wait for other events to be detected before controlling the compressor to enter other states. For example, when a start event is detected, the compressor is controlled to enter start mode. When the shutdown duration from shutdown to the current time is greater than or equal to the shutdown duration parameter, the compressor is controlled to start.

[0106] In this embodiment, in electronic devices with cooling and / or heating functions, the shutdown state ensures that the compressor can only shut down when the time interval between starting and stopping reaches the start-stop duration parameter. In the shutdown state, the compressor can only stop when the runtime from startup to the current moment is greater than or equal to the startup duration parameter. That is, the compressor enters the shutdown state when it receives a shutdown event trigger command, and can only stop when the runtime reaches the minimum runtime corresponding to the current number of start-stop cycles, thereby preventing damage to the compressor due to frequent shutdowns.

[0107] In step S204, the start / stop duration parameters include the stop duration parameters, such as... Figure 4 As shown, controlling the compressor's start-up and shutdown based on the corrected start-up / shutdown duration parameters and the current state may further include the following steps:

[0108] S401, when the current state is the start state, determine the shutdown time of the compressor from when it stops running until the current moment.

[0109] In some embodiments, the start / stop duration parameter includes a stop duration parameter, which is the shortest stop duration corresponding to the current number of start / stop cycles. Controlling the compressor's start / stop based on the corrected start / stop duration parameter and the current state can be as follows: Controlling the compressor's start based on the corrected stop duration parameter and the current state. When the compressor's current state is the start state, controlling the compressor's start first determines the stop duration from when the compressor stopped running until the current moment, and then controls the compressor's start in subsequent steps.

[0110] S402, when the shutdown duration is greater than or equal to the shutdown duration parameter, controls the compressor to start and triggers the start-up completion event.

[0111] In some embodiments, when the compressor is in the start state, after determining the shutdown time of the compressor from shutdown to the current time, it can be determined whether the shutdown time of the compressor is greater than or equal to the shutdown time parameter. When the shutdown time is greater than or equal to the shutdown time parameter, the compressor is controlled to start, and a start-up completion event can be triggered at the same time. In subsequent steps, the compressor is controlled to enter the running state.

[0112] For example, the compressor's shutdown duration from shutdown to the current moment is 15 minutes, and the shutdown duration parameter is 8 minutes. The compressor's shutdown duration is longer than the shutdown duration parameter, so the compressor is controlled to start and a start-up completion event is triggered. In subsequent steps, the compressor is controlled to enter the running state.

[0113] S403 controls the compressor to enter the running state when a start-up completion event is detected.

[0114] In some embodiments, when the shutdown duration from the compressor's shutdown to the current moment is greater than the shutdown duration parameter, the compressor is controlled to start and a start-up completion event is triggered. When the start-up completion event is detected, it indicates that the compressor has finished starting and can be put into operation. At this time, the compressor can be controlled to enter the running state.

[0115] In this embodiment, in electronic devices with cooling and / or heating functions, the start-up state ensures that the compressor can only start when the time interval between shutdown and restart reaches the shutdown duration parameter. In the start-up state, the compressor can only start when the shutdown duration from shutdown to the current moment is greater than or equal to the shutdown duration parameter. That is, the compressor enters the start-up state when it receives a start-up event trigger command, and can only start when the shutdown duration reaches the shutdown duration corresponding to the current number of start-stop cycles, thereby preventing damage to the compressor due to frequent starts.

[0116] In some embodiments, when the compressor is in a start-up state, a stop state, or a running state, an emergency stop event can be triggered and the compressor enters an emergency stop state when the compressor is detected to be powered off. When the compressor is detected to be powered back on, an emergency stop completion event is triggered and the compressor enters a normal standby state.

[0117] In step S301, the shutdown state includes a first shutdown state and a second shutdown state. The compressor state control method provided in this application embodiment further includes:

[0118] When a shutdown event is detected, a first shutdown control command is output to control the compressor to enter a first shutdown state; or when an abnormal event is detected, a second shutdown control command is output to control the compressor to enter a second shutdown state; wherein, in the second shutdown state, the compressor enters the first shutdown state in response to an abnormal recovery event.

[0119] In some embodiments, the first shutdown state is a normal shutdown state, and the second shutdown state is an abnormal shutdown state. When a shutdown event is detected, such as when a user turns off an electronic device with cooling and / or heating functions, a first shutdown control command, i.e., a normal shutdown control command, is output to control the compressor to enter a normal shutdown state. After the compressor completes shutdown in the normal shutdown state, it stops cooling or heating. When an abnormal event is detected, a second shutdown control command, an abnormal shutdown control command, is output to control the compressor to enter an abnormal shutdown state. If an abnormal recovery event is detected before the compressor has completed shutdown in the abnormal shutdown state, it returns to the normal shutdown state in response to the abnormal recovery event. If the runtime meets the minimum shutdown event requirement, the compressor is controlled to stop and a shutdown completion event is triggered, entering the corresponding abnormal standby state.

[0120] In step S303, the standby state includes a first standby state and a second standby state. When a shutdown completion event is detected, controlling the compressor to enter the standby state includes:

[0121] When a shutdown completion event is detected in the first shutdown state, the compressor is controlled to enter the first standby state; or when a shutdown completion event is detected in the second shutdown state, the compressor is controlled to enter the second standby state; wherein, the compressor enters the first standby state in response to an abnormal recovery event in the second standby state.

[0122] In some embodiments, the first standby state is a normal standby state, and the second standby state is an abnormal standby state. When a shutdown completion event is detected in the normal shutdown state, for example, when the compressor's runtime from startup to the current moment exceeds the startup duration parameter, the compressor is controlled to enter the normal standby state. At this time, the compressor waits for other events to trigger so it can enter other states. When a shutdown completion event is detected in the abnormal shutdown state, the compressor is controlled to enter the abnormal standby state. If an abnormal recovery event is detected in the abnormal standby state, the compressor can recover to the normal standby state in response to the abnormal recovery event.

[0123] In step S301, in the above embodiments, the second shutdown state, i.e., the abnormal standby state, includes a locked shutdown state; the abnormal event includes a locking event; and the abnormal recovery event includes an unlocking event. The compressor state control method provided in this application embodiment further includes:

[0124] When the compressor body tilt angle is detected to be greater than or equal to the first preset tilt angle or the compressor is in a power switching state, a locking event is triggered to enter the locked shutdown state; or in the locked shutdown state, when the compressor body tilt angle is detected to be less than the second preset tilt angle or the power supply to the compressor is stable, an unlocking event is triggered to enter the first shutdown state.

[0125] In some embodiments, a locking event may include situations such as the compressor's body tilt angle being greater than or equal to a preset tilt angle or the compressor being in a power switching state. An unlocking event may include situations such as the compressor's body tilt angle being less than a preset tilt angle or the compressor's power supply being stable. The magnitude of the preset tilt angle can be determined according to the specific circumstances in the actual application scenario and is not limited here.

[0126] Accordingly, when the compressor's tilt angle is detected to be greater than or equal to a preset tilt angle, or when the compressor is in a power switching state, a locking event is triggered, controlling the compressor to enter a locked shutdown state. The compressor can stop when the runtime from startup to the current moment is greater than or equal to the startup duration parameter. In the locked shutdown state, when the compressor's tilt angle is detected to be less than a preset tilt angle, or when the compressor's power supply is stable, an unlocking event is triggered, and in response to the unlocking event, the compressor enters a normal shutdown state.

[0127] It should be noted that when the compressor body is tilted, the lubricating oil level will change, which may lead to increased compressor wear or even damage. Therefore, the compressor should be stopped immediately to avoid irreversible damage. When the compressor is in a power switching state, the power supply may be interrupted briefly, preventing the compressor from continuing to work. Therefore, in both of these situations, the compressor should be stopped and locked, and should not be restarted or run until normal operation is restored, thus preventing compressor damage.

[0128] For example, the preset tilt angle when the compressor triggers a lock or unlock event is set to 10°. When the compressor body tilt angle is detected to be greater than or equal to 10°, a lock event is triggered, and a stop control command is output to control the compressor to enter a locked stop state. The compressor can stop when the runtime from startup to the current moment is greater than the startup duration parameter. In the locked stop state, when the compressor body tilt angle is detected to be less than 10°, an unlock event is triggered, and the compressor enters a normal stop state in response to the unlock event.

[0129] In the above embodiments, the second shutdown state also includes a fault shutdown state, the abnormal event also includes a fault event, the abnormal recovery event also includes a fault recovery event, and the compressor state control method provided in this application embodiment further includes:

[0130] When a compressor fault is detected, a fault event is triggered to enter a fault shutdown state; or, in the fault shutdown state, when the compressor fault is detected to be resolved, a fault recovery event is triggered to enter a first shutdown state.

[0131] In some embodiments, a fault event may include a compressor undervoltage, phase loss, or abnormal vibration; a fault recovery event may include a compressor without undervoltage, phase loss, or abnormal vibration.

[0132] Accordingly, when a compressor fault such as undervoltage, phase loss, or abnormal vibration is detected, a fault event is triggered, controlling the compressor to enter a fault shutdown state. The compressor can be shut down when the runtime from startup to the current moment is greater than or equal to the startup duration parameter. In the fault shutdown state, when the compressor fault is cleared (i.e., the compressor is no longer undervoltage, has no phase loss, or is not abnormally vibrating), a fault recovery event is triggered, and in response to the fault recovery event, the compressor enters a normal shutdown state.

[0133] It should be noted that when the compressor is undervoltage (i.e., insufficient voltage), the operating voltage is lower than the rated voltage by 15%; when the compressor experiences a phase loss (i.e., one phase of the normal three-phase power supply is broken), the compressor will reduce its output power and fail to operate normally or may malfunction; when the compressor experiences abnormal vibration, it will not operate normally. In these three situations, the compressor will be shut down to protect it and prevent damage.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
