[0032] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0033] The following describes a method and device for monitoring a closed air supply unit of an air suspension system according to an embodiment of the present application with reference to the accompanying drawings.

[0034] Figure 1 Schematic diagram of the structure of a closed air supply unit of an air suspension system provided in an embodiment of the present application. Figure 1 The closed air supply unit includes a brushless motor, a compressor assembly, a pump body, a pressure limiting valve, a one-way valve, an air filter, a low-pressure end dryer, an exhaust valve, a manual exhaust bolt, a switching valve, an air valve, an air spring, a high-pressure end dryer and an air tank. The closed air supply unit, through the action of the brushless motor, the compressor assembly and the pump body, filters and dries the air in the air tank, and then compresses it into the air spring under the control of the above-mentioned various solenoid valves, so that the air spring plays the role of a suspension. Correspondingly, the air in the air spring can also be released by adjusting the solenoid valve, and then returned to the air tank after drying. The above-mentioned components can control the air springs of the air suspension system by compressed air to play the role of a suspension.

[0035] In an embodiment of the present application, a temperature sensor, a pressure sensor and a humidity sensor are arranged in the closed air supply unit, and the operating status of the dryer in the closed air supply unit is monitored by the temperature sensor, the pressure sensor and the humidity sensor to obtain the operating status parameters of the dryer in the closed air supply unit.

[0036] In some embodiments, the temperature sensor is used to monitor the real-time temperature of the dryer during current operation; the pressure sensor is used to monitor the real-time pressure of the dryer during current operation; and the humidity sensor is used to monitor the real-time humidity of the dryer during current operation.

[0037] In some embodiments, the temperature sensor, the pressure sensor and the humidity sensor may be arranged on the valve body, and the valve body may include a plurality of solenoid valves, for example, including various air valves, switching valves and exhaust valves in a closed air supply unit.

[0038] In some embodiments, the temperature sensor, pressure sensor, and humidity sensor may be an integrated three-in-one sensor.

[0039] In some embodiments, a three-in-one sensor is arranged on the valve body, and can monitor the temperature, pressure and humidity in the air circulation path corresponding to the wheel.

[0040] In some embodiments, the three-in-one sensor is disposed on the valve body and is close to the inlet and outlet ends of the air spring.

[0041] In some embodiments, the air conditioning spring is controlled by a corresponding solenoid valve. It is understood that the solenoid valve can play a role in controlling the direction of air flow in the air suspension system, including an air valve and a switching valve.

[0042] Air valve: When the air spring needs to be inflated, the air valve will be opened. At this time, compressed air enters the air spring through the air valve, increasing the air pressure in the air spring, thereby pushing the vehicle body upward.

[0043] Switching valve: When the air pressure in the air spring needs to be reduced, the switching valve is opened. At this time, the air in the air spring is discharged into the atmosphere through the switching valve, reducing the air pressure in the air spring and allowing the vehicle body to move downward.

[0044] In some embodiments, the change in vehicle height can be determined based on an output signal from a height sensor installed on the vehicle, thereby controlling the opening and closing of the inflation valve and the deflation valve, thereby achieving precise control of the vehicle height.

[0045] The following figure combines Figure 1 The closed air supply unit of the air suspension system is described below, and the monitoring method and device of the closed air supply unit of the air suspension system provided in the embodiment of the present application are explained.

[0046] Figure 2 A flow chart of a monitoring method for a closed air supply unit of an air suspension system provided in an embodiment of the present application. The monitoring method can be applied to the closed air supply unit of the air suspension system described in the above embodiment, and can also be applied to closed air supply units of other forms of air suspension systems. The number here is only for quantity, and the scope of application is not limited.

[0047] like Figure 2 As shown, the monitoring method includes but is not limited to the following steps:

[0048] S201, collecting operating status parameters of the dryer in the closed air supply unit through a temperature sensor, a pressure sensor and a humidity sensor.

[0049] In some embodiments, the temperature sensor is used to monitor the real-time temperature of the dryer during current operation; the pressure sensor is used to monitor the real-time pressure of the dryer during current operation; and the humidity sensor is used to monitor the real-time humidity of the dryer during current operation.

[0050] In some embodiments, the temperature sensor, pressure sensor, and humidity sensor may be an integrated three-in-one sensor.

[0051] In some embodiments, the data acquisition unit may acquire operating status parameters of the dryer in the closed air supply unit through a temperature sensor, a pressure sensor, and a humidity sensor.

[0052] In the embodiment of the present application, the use of a three-in-one temperature, pressure, and humidity sensor (P / T / H) for real-time monitoring can improve measurement accuracy, ensure data accuracy and reliability, and provide a more reliable basis for evaluating the performance and life of the dryer.

[0053] S202: predicting information related to the life of the dryer according to the operating status parameters.

[0054] In some embodiments, the life of the dryer may be predicted based on the operating status parameters to obtain information related to the life of the dryer.

[0055] In some embodiments, the mapping relationship between the operating status parameters and the lifespan may be pre-calibrated, and after the operating status parameters are acquired, the lifespan-related information of the dryer may be determined in combination with the mapping relationship.

[0056] Optionally, the mapping relationship may be a mapping function, the operating state parameter is a known quantity, the operating state parameter is input into the mapping function, and information related to the life of the dryer is obtained through function calculation.

[0057] Optionally, the mapping relationship may be a mapping relationship table. After the operating state parameters are determined, the mapping relationship table may be queried to obtain life-related information matching the operating state parameters as the life-related information of the dryer.

[0058] Optionally, if the operating status parameter does not exist in the mapping relationship table, a similar operating status parameter closest to the operating status parameter can be obtained from the mapping relationship table to obtain life-related information matching the similar operating status parameter as the life-related information of the dryer.

[0059] Optionally, if the operating status parameter does not exist in the mapping relationship table, the first operating status parameter and the second operating status parameter adjacent to the operating status parameter can be obtained from the mapping relationship table to obtain life-related information that matches the first operating status parameter and the second operating status parameter respectively, and the respectively matching life-related information is interpolated or averaged to obtain life-related information of the dryer.

[0060] In some embodiments, the initial life prediction model can be trained based on the sample operating state parameters, and the target life prediction model can be obtained after the training end conditions are met.

[0061] Furthermore, after obtaining the operating status parameters, the target life prediction model can be called and the operating status parameters can be input into the target life prediction model. The target life prediction model predicts the life of the dryer according to the operating status parameters to obtain information related to the life of the dryer.

[0062] In the embodiment of the present application, the life prediction model is used to accurately predict the life and performance of the dryer, which can improve the accuracy of the prediction, and can detect and solve problems more promptly. Furthermore, regular maintenance can be performed by providing feedback to the driver, which can effectively avoid the problems of rust and jamming of the solenoid valve in the air supply unit. Moreover, by accurately predicting the life and performance of the dryer, unnecessary maintenance and replacement can be effectively reduced, maintenance costs can be reduced, and economic benefits can be improved.

[0063] S203: Generate a maintenance task for the dryer according to the life-related information and the operating status parameters, wherein the maintenance task at least includes a maintenance suggestion for the dryer.

[0064] In some embodiments, the predicted remaining life of the dryer is determined based on the life-related information, and in response to the predicted remaining life being less than a set life threshold, a maintenance task for the dryer is generated based on the operating state parameters. In the embodiments of the present application, through real-time detection and prediction, problems and maintenance components can be fed back in a timely manner, abnormal conditions in the system can be responded to quickly, and the response speed and reliability of the system are improved.

[0065] In some embodiments, the abnormal condition of the dryer can be determined based on the operating status parameters, and different maintenance tasks can be generated for different abnormal conditions.

[0066] In some embodiments, after the maintenance task is obtained, the contact associated with the vehicle can be determined, and the maintenance task can be sent to the terminal device of the contact.

[0067] In some embodiments, while sending the maintenance task, an alarm message may be synchronously sent to the terminal device, and the alarm message may include at least one of life-related information, operating status parameters, and abnormal conditions.

[0068] In the embodiment of the present application, the operating status of the dryer can be monitored in real time through sensor technology, so that problems can be discovered and solved in time, and problems such as rust and jamming of the solenoid valve in the air supply unit can be avoided, thereby ensuring the normal operation of the air suspension system. Moreover, the operating status monitored by the sensor can be used to estimate the performance life of the dryer, which can effectively improve the reliability and stability of the air suspension system, thereby improving ride comfort and vehicle handling stability. Moreover, by predicting the performance life of the dryer, accurate maintenance suggestions can be provided to the driver, or maintenance and replacement can be performed in time to avoid problems caused by dryer failure, thereby improving the maintenance efficiency and service life of the vehicle. Furthermore, in the field of dryer life estimation, model prediction can improve the accuracy and reliability of the prediction, and is conducive to promoting the development and application of related technologies. In summary, in the field of air suspension systems, sensor technology and dryer performance life estimation models have broad application prospects.

[0069] Figure 3 A flow chart of another method for monitoring a closed air supply unit of an air suspension system provided in an embodiment of the present application. The monitoring method can be applied to the closed air supply unit of the air suspension system described in the above embodiment, and can also be applied to closed air supply units of other forms of air suspension systems. The number here is only for quantity, and the scope of application is not limited.

[0070] like Figure 3 As shown, the monitoring method includes but is not limited to the following steps:

[0071] S301, collecting operating status parameters of the dryer in the closed air supply unit through a temperature sensor, a pressure sensor and a humidity sensor.

[0072] S302: Determine whether the dryer currently has an operation risk based on the operation status parameters.

[0073] S303: In response to the dryer currently having an operation risk, generate alarm information for the dryer.

[0074] In some embodiments, the change amount of the operating status parameter is obtained according to the operating status parameter, and in response to the change amount of the operating status parameter being greater than a set change amount threshold, it is determined that the dryer currently has an abnormal operating condition.

[0075] In some embodiments, the temperature variation can be obtained based on the real-time temperature collected by the temperature sensor, and in response to the temperature variation being greater than a set temperature variation threshold, it is determined that the dryer currently has an over-temperature abnormality. In some embodiments, the pressure variation can be obtained based on the real-time pressure collected by the pressure sensor, and in response to the pressure variation being greater than a set pressure variation threshold, it is determined that the dryer currently has an over-pressure abnormality.

[0076] In some embodiments, the humidity change can be obtained based on the real-time humidity collected by the pressure sensor, and in response to the humidity change being greater than a set humidity change threshold, it is determined that the dryer currently has an abnormal over-humidity condition.

[0077] In some embodiments, the data may be collected periodically, and the change amount corresponding to the operating status parameter may be determined based on the operating status parameter collected within the period.

[0078] In some embodiments, a temperature model, a pressure model, and a humidity model may be constructed, and the collected temperature, pressure, and humidity may be distributed and input into the respective corresponding models, and the models may output corresponding changes.

[0079] It is understandable that if the dryer is in an over-temperature operation state, an over-pressure operation state and / or an over-humidity operation state for a long time, it may cause damage to the dryer, for example, the solenoid valve may be rusted or stuck. In order to achieve safe operation of the dryer, after identifying that the dryer has an abnormal operation, an alarm message of the dryer may be generated.

[0080] Optionally, different alarm information may be generated for different abnormal operation situations.

[0081] In some embodiments, after determining that an operating abnormality exists, the contact person associated with the vehicle can be determined, and an alarm message can be sent to the contact person's terminal device to attract the contact person's attention so that the working condition of the closed air supply unit can be adjusted to eliminate the operating abnormality, reduce operating risks, and thereby extend the service life of the dryer.

[0082] S304: predicting information related to the life of the dryer according to the operating status parameters.

[0083] S305: Generate a maintenance task for the dryer according to the life-related information and the abnormal operation situation, wherein the maintenance task at least includes a maintenance suggestion for the dryer.

[0084] In some embodiments, in some embodiments, a predicted remaining life of the dryer is determined based on life-related information, and in response to the predicted remaining life being less than a set life threshold, a maintenance task for the dryer is generated based on an abnormal operation condition.

[0085] In some implementation examples, if the abnormal operating condition is overheating of the dryer, a first maintenance task can be generated. The first maintenance task can include maintenance suggestions for cooling the dryer, for example, reducing the output power of the brushless motor, reducing the operating current and voltage of the closed air supply unit, etc.

[0086] In some implementation examples, if the abnormal operating condition is dryer overpressure, a second maintenance task may be generated, which may include a maintenance suggestion for depressurizing the dryer, for example, the amount of air entering the air spring may be reduced.

[0087] In some implementation examples, if the abnormal operation condition is that the dryer is over-humidified, a third maintenance task may be generated. The third maintenance task may include a maintenance suggestion for reducing the humidity of the dryer, such as increasing the working parameters of the dehumidification in the air filter.

[0088] In some implementations, the monitored operating status parameters may be stored, and optionally, information related to the life of the dryer, maintenance tasks, etc. may also be stored.

[0089] In the embodiment of the present application, the operating status of the dryer can be monitored in real time through sensor technology, so that problems can be discovered and solved in time, and problems such as rust and jamming of the solenoid valve in the air supply unit can be avoided, thereby ensuring the normal operation of the air suspension system. Moreover, the operating status monitored by the sensor can be used to estimate the performance life of the dryer, which can effectively improve the reliability and stability of the air suspension system, thereby improving ride comfort and vehicle handling stability. Moreover, by predicting the performance life of the dryer, accurate maintenance suggestions can be provided to the driver, or maintenance and replacement can be performed in time to avoid problems caused by dryer failure, thereby improving the maintenance efficiency and service life of the vehicle. Furthermore, in the field of dryer life estimation, model prediction can improve the accuracy and reliability of the prediction, and is conducive to promoting the development and application of related technologies. In summary, in the field of air suspension systems, sensor technology and dryer performance life estimation models have broad application prospects.
