[0002] With the rapid development of intelligent driving technology, sensors, as a component of intelligent driving systems, are hailed as the "eyes" of these systems. Their performance and reliability directly determine the safety and accuracy of intelligent driving. Intelligent driving relies on sensors to accurately perceive the environment, capturing information from the external environment to assist in vehicle navigation, obstacle avoidance, and decision-making. However, in daily use, sensor surfaces are easily covered by contaminants such as dust, dirt, rainwater, and snow. These contaminants not only reduce the sensor's perception accuracy but also cause data distortion, thus affecting the normal operation of the intelligent driving system.

[0027] As used in this paper, the term "model" refers to a system that learns the relationship between inputs and outputs from training data, enabling it to generate corresponding outputs for a given input after training. Model generation can be based on machine learning techniques. Deep learning is a machine learning algorithm that uses multiple layers of processing units to process inputs and provide corresponding outputs. In this paper, "model" may also be referred to as a "machine learning model," a "machine learning network," or simply a "network," and these terms are used interchangeably.

As used herein, a set of elements or similar expressions can include one or more such elements. For example, “a set of convolutional units” can include one or more convolutional units.

[0029] As briefly mentioned earlier, there are several issues with sensor cleaning. Specifically, existing sensor cleaning systems use an air pump as the direct air source. The air pump directly supplies compressed air to the cleaning nozzles, achieving gaseous or gas-liquid cleaning of the sensor surface through the jet of air. Secondly, existing sensor cleaning systems generate compressed air using an air pump and store it in an air tank (described below), then supply air to the cleaning nozzles through the air tank. This method can alleviate the instability of the air pump's output pressure to some extent and improve the cleaning efficiency of the system. Furthermore, existing sensor cleaning systems use a blower as the direct air source. The blower provides low-pressure gas to the nozzles through an air duct for cleaning the sensor surface.

[0030] However, while existing sensor cleaning systems meet the needs of intelligent driving sensor cleaning to a certain extent, they still have many shortcomings, which will be described one by one below.

[0031] Specifically, for air pumps used as a direct air source, the lack of a buffer tank means that the compressed air directly output by the pump is prone to pressure fluctuations under high pressure or high flow conditions, affecting cleaning effectiveness and equipment operational stability. When the gas outlet is closed, the reverse airflow impact can cause overpressure damage to the air pump, reducing its service life. Secondly, without a buffer tank, moisture and oil in the compressed air are difficult to remove effectively, affecting the quality of the clean airflow. Furthermore, the lack of a buffer tank can lead to uneven pipeline pressure, potentially causing safety issues such as rebound, explosion, or bending.

[0032] When the air pump and storage tank are arranged separately, assembly is complex, time-consuming, and prone to leaks. This separate arrangement requires additional connecting pipes and fittings, increasing installation complexity and potential sealing issues. Furthermore, it raises production, maintenance, and system integration costs. Additionally, independent placement of the air pump and storage tank increases the space occupied by the cleaning system. Simultaneously, the stability and reliability of the cleaning system are poor. The additional connecting pipes and fittings introduce extra resistance and add multiple connection points, which can lead to gas leaks or pressure losses, reducing the overall performance of the cleaning system.

[0033] Using blowers as a direct air source is problematic. Blowers can only produce low-pressure gas, limiting their applicability and making it difficult to meet high-pressure cleaning requirements.

[0034] To address, or at least partially address, the aforementioned problems or other potential problems of existing gas supply devices for sensor cleaning systems, embodiments of this disclosure provide a gas supply device and a sensor cleaning system solution for a sensor cleaning system. The gas supply device includes a housing and a pressurized gas storage assembly. Further, the housing includes a gas inlet and a gas outlet, the gas outlet being coupled to a nozzle assembly of the sensor cleaning system. Further, the pressurized gas storage assembly is disposed within the housing and includes a pump and a gas storage container. The pump is disposed within the housing and includes an outlet and an inlet coupled to the gas inlet, the pump being adapted to pressurize gas entering from the inlet and discharge it from the outlet. The gas storage container is disposed within the housing and includes a high-pressure outlet and a high-pressure inlet coupled to the outlet of the pump, the gas storage container being adapted to store gas entering from the high-pressure inlet, and the high-pressure outlet being coupled to the gas outlet to deliver high-pressure gas to the nozzle assembly as needed.

[0035] In this way, by integrating the gas source device inside the housing, efficient gas pressurization, stable storage, and continuous output are ensured. This gas source device, through its modular integrated structure, simplifies installation and maintenance processes, reduces operating costs, and provides an efficient, stable, and reliable gas source for gas or liquid cleaning devices (such as sensor cleaning systems), ensuring the stability of cleaning effects and the reliability of the gas source device's operation. It is suitable for a variety of complex application scenarios.

[0036] An example structure of a sensor cleaning system will be described below. The sensor cleaning system according to an embodiment of this disclosure includes an air source device 100 and a nozzle assembly. The air source device 100 is coupled to the nozzle assembly and is designed to ensure the cleanliness of the sensor surface through efficient air supply and precise gas injection, thereby ensuring the normal operation and accurate detection of the sensor.

[0037] Specifically, the gas source device 100 is used to provide a stable high-pressure gas source, and the gas source device 100 supports fault diagnosis, fault reporting and intelligent fault handling functions, which further ensures the safety of the operation of the gas source device 100. Its specific structure and functions will be described in detail below.

[0038] It is understood that fault diagnosis includes temperature diagnosis and feedback, short circuit diagnosis and feedback, open circuit diagnosis and feedback, and overcurrent diagnosis and feedback. Protection functions include over-temperature and over-voltage protection, short circuit protection, overcurrent protection, and open circuit protection, but the embodiments in this disclosure do not specifically limit these functions.

[0039] Furthermore, the nozzle assembly is arranged near the target sensor and connected to the gas outlet 1102 of the gas source device 100 via a pipeline, which is used to spray the gas output by the gas source device 100 onto the sensor surface at an appropriate speed, pressure and angle to remove dust, particulate matter, water droplets or other deposits.

[0040] In some embodiments, the nozzle assembly may employ a single nozzle, multiple nozzles, or adjustable nozzles to accommodate different sensor types and cleaning needs. The nozzle shape may include at least one of conical, fan-shaped, or cylindrical shapes, with the specific shape and size selected according to the desired spray effect.

[0041] The nozzle assembly can be positioned according to actual needs to ensure that the jet airflow can fully cover the sensor's sensing area while avoiding excessive mechanical impact or other damage to the sensor. The distance and angle between the nozzle and the sensor can be adjusted according to the specific size and shape of the sensor, and this disclosure does not impose specific limitations on these aspects.

[0042] Furthermore, the nozzle assembly can be linked with the output pressure regulating device 1302 of the air source device 100 to adjust the pressure and flow rate of the injected gas, thereby adapting to cleaning under different environmental conditions. The specific output pressure regulating device 1302 will be described in detail below.

[0043] In this way, the sensor cleaning system achieves efficient cleaning of the sensor through the efficient collaborative work of the air source device 100 and the nozzle assembly, effectively improving the sensor's service life and detection accuracy, and providing a reliable guarantee for the normal operation of the sensor in various complex environments.

[0044] Meanwhile, this sensor cleaning system can be applied to fields such as autonomous vehicles, industrial automation equipment, and medical testing instruments, and is especially suitable for application scenarios with high requirements for cleaning quality and operational stability. The embodiments disclosed herein do not specifically limit this.

[0045] The specific structure of the air source device 100 for the sensor cleaning system will now be described with reference to Figure 1. In the embodiments of this disclosure, the air source device 100 generally includes a housing and a pressurized air storage assembly 130, designed to provide a stable and efficient air source for sensor cleaning.

[0046] Specifically, the housing is the external structure of the gas source device 100, and its interior houses the pressurized gas storage assembly 130. The housing is provided with a gas inlet 1101 and a gas outlet 1102 for gas input and output. The gas inlet 1101 is coupled to the air inlet of the air pump 120 for introducing external air; the gas outlet 1102 is connected to the nozzle assembly of the sensor cleaning system for delivering high-pressure gas to complete the cleaning task.

[0047] Furthermore, an air pump 120 is arranged within the housing, with its inlet coupled to the gas inlet 1101 of the housing for receiving external air. The air pump 120 pressurizes the gas entering from the inlet and discharges the high-pressure gas through its outlet. The air pump 120 can be selected according to actual displacement requirements, and the embodiments of this disclosure do not specifically limit this selection.

[0048] Furthermore, the pressurized gas storage assembly 130 includes a gas storage container 1301. This gas storage container 1301 is connected to the outlet of the air pump 120 and has a high-pressure inlet and a high-pressure outlet. High-pressure gas discharged from the air pump 120 enters the gas storage container 1301 through the high-pressure inlet and is stored within it. The gas storage container 1301 is connected to the gas outlet 1102 of the housing through its high-pressure outlet, enabling it to output high-pressure gas at a stable pressure according to the requirements of the sensor cleaning system. The gas storage container 1301 can be made of rust-resistant material, and its volume can be selected according to actual needs.

[0049] When the gas source device 100 is working, external air enters the air pump 120 through the gas inlet 1101 of the housing. After the air pump 120 pressurizes the air, it delivers the high-pressure gas to the high-pressure inlet of the gas storage container 1301 through the outlet. The gas storage container 1301 is used to store high-pressure gas and ensure that the gas is output to the sensor cleaning system at a stable pressure.

[0050] Furthermore, the high-pressure gas inside the gas storage container 1301 is delivered to the nozzle assembly through its high-pressure outlet and the gas outlet 1102 of the housing. The nozzle assembly uses the high-pressure gas to clean the sensor surface, removing dust, dirt, rainwater, or other contaminants to ensure the normal operation of the sensor.

[0051] In this way, both the air pump 120 and the air storage container 1301 are arranged inside the housing, forming an integrated layout that reduces space occupation and facilitates installation and placement. The high-pressure gas in the air storage container 1301 can meet the cleaning system's requirement for stable pressure, providing a continuous high-pressure gas output even when the air pump 120 operates intermittently. This air source device 100 is suitable for various sensor cleaning system scenarios, including vehicle sensor cleaning and industrial equipment cleaning, and can be configured according to different cleaning needs. The integration of the air pump 120 and the air storage container 1301 reduces connection points, lowers airflow loss, improves gas transmission efficiency, and enhances the reliability and safety of the sensor cleaning system. Furthermore, the housing facilitates maintenance, and the air pump 120 and air storage container 1301 can be modularly replaced and repaired, thereby reducing maintenance costs and time.

[0052] Meanwhile, the air source device 100 is used in sensor cleaning systems and can also be applied to other systems that require a stable air source, such as industrial automation equipment, medical air source systems, pneumatic tools, etc.

[0053] In some embodiments, the gas source device 100 further includes an output pressure regulating device 1302. The output pressure regulating device 1302 is disposed between the high-pressure outlet of the gas storage container 1301 and the gas outlet 1102, and is used to regulate the pressure of the gas output by the gas source device 100 to ensure the safety and efficiency of the sensor cleaning system.

[0054] Furthermore, the output pressure regulating device 1302 is connected to the high-pressure outlet of the gas storage container 1301 via a pipe or interface, and is also connected to the gas outlet 1102 of the housing. The output pressure regulating device 1302 can adjust the gas pressure discharged from the gas storage container 1301 according to usage requirements to match the operational needs of the sensor cleaning system. The output pressure regulating device 1302 can eliminate pressure fluctuations in the gas storage container 1301, outputting a stable working pressure and improving the consistency of cleaning results.

[0055] Furthermore, users can configure the output pressure of the output pressure regulating device 1302 through an external control interface (such as a control panel or remote interface). Specifically, the adjustment range can be from 0.5 bar to 15 bar, but this is not specifically limited in the embodiments of this disclosure, and the adjustment range can be selected according to specific application requirements. Further, the output pressure fluctuation is less than ±0.1 bar, ensuring high-precision operation of the sensor cleaning system.

[0056] When outside air enters the air pump 120 through the gas inlet 1101 of the casing, the air pump 120 pressurizes the gas and sends it into the gas storage container 1301 through its outlet. The high-pressure gas stored in the gas storage container 1301 provides a stable gas source for the cleaning system.

[0057] High-pressure gas in the gas storage container 1301 flows to the output pressure regulating device 1302 through the high-pressure outlet, and the regulating device controls the gas pressure in real time. The regulated gas is then delivered to the nozzle assembly of the cleaning system through the gas outlet 1102 of the housing to clean the sensor surface at the required pressure.

[0058] With its pressure regulating device, the air source device 100 can adapt to different types of sensor cleaning needs. For example, for dust removal, a lower pressure (e.g., 1-3 bar) is required; while for cleaning stubborn dirt, a higher pressure (e.g., 8-12 bar) is required.

[0059] The output pressure regulating device 1302 differentially controls the pressure of the air pump 120 and the air storage container 1301 with the output pressure to ensure precise pressure matching during the cleaning process, improve the stability and continuity of the output pressure, and at the same time avoid damage to the sensor caused by excessive pressure, ensuring sufficient cleaning force to remove contaminants and improve cleaning efficiency.

[0060] In scenarios such as autonomous driving, the output pressure regulating device 1302 eliminates pressure fluctuations within the gas storage container 1301 through intelligent control or mechanical adjustment, making the output pressure more stable. For example, the maximum stable output pressure is 20 bar, and the maximum withstand pressure is 25 bar.

[0061] In some embodiments, the output pressure regulating device 1302 is equipped with a safety protection function. For example, when the output pressure is detected to exceed the set range, the output pressure regulating device 1302 can quickly reduce the pressure through an internal pressure relief mechanism to prevent damage to the sensor cleaning system and the object being cleaned.

[0062] The high-pressure gas regulated by the output pressure regulating device 1302 can remove dust, mud, and water droplets from the sensor surface, ensuring the sensor's accurate measurement capability.

[0063] In some embodiments, the pressurized gas storage assembly 130 further includes a one-way valve 1303. The one-way valve 1303 is arranged between the output pressure regulating device 1302 and the high-pressure outlet of the gas storage container 1301 to prevent gas from flowing back from the high-pressure outlet to the gas storage container 1301, thereby improving the safety and efficiency of system operation.

[0064] Furthermore, the one-way valve 1303 allows gas to flow in only one direction, that is, from the high-pressure outlet of the gas storage container 1301 to the output pressure regulating device 1302, while preventing any form of gas backflow.

[0065] During operation, the high-pressure gas in the gas storage container 1301 is discharged through the high-pressure outlet, flows through the one-way valve 1303 and reaches the output pressure regulating device 1302, and then is delivered to the nozzle assembly of the sensor cleaning system through the gas outlet 1102 for use.

[0066] The one-way valve 1303 ensures that the gas can only flow in one direction, preventing the gas from flowing back to the gas storage container 1301, thereby avoiding sensor cleaning system malfunction or safety issues of the gas storage container 1301 caused by abnormal pressure.

[0067] The one-way valve 1303 can also isolate the direct connection between the gas storage container 1301 and the subsequent gas circuit when the output pressure regulating device 1302 fails or the pressure fluctuates, ensuring that the gas storage container 1301 maintains a stable pressure state inside.

[0068] The one-way valve 1303 can adopt a low pressure drop structure, resulting in less pressure loss when gas passes through the valve, thus improving the energy efficiency of the sensor cleaning system.

[0069] The one-way valve 1303 has a fast opening and closing response speed, enabling precise control even in scenarios with rapid airflow changes.

[0070] The one-way valve 1303 can be selected according to the different application requirements of the air source device 100, and supports a variety of materials and specifications, such as stainless steel and corrosion-resistant alloys, to adapt to complex working environments.

[0071] In some embodiments, the gas source device 100 further includes a control component 140. The control component 140 is coupled to the pressurized gas storage component 130. The control component 140 may be integrated inside the gas source device 100 or may exist as a separate controller.

[0072] Furthermore, the control component 140 includes a sensor module and a control circuit 1404. The sensor module and control circuit can acquire various parameters (such as at least one of pressure and temperature) during the operation of the gas source device 100, and dynamically adjust the operation of the pressurized gas storage component 130 based on these parameters.

[0073] Furthermore, the predetermined locations where the sensor module is arranged include at least one of the following: the gas inlet 1101 and gas outlet 1102 of the housing, the interior of the gas storage container 1301, the high-pressure inlet and high-pressure outlet of the gas storage container 1301, and the inlet and outlet of the air pump 120.

[0074] Pre-defined positions are arranged at the gas inlet 1101 and gas outlet 1102 of the housing to monitor the pressure and temperature of the incoming and outgoing gas, and to ensure that the gas source device 100 has pressure balance at the input and output ends.

[0075] In some embodiments, the predetermined location may include an appropriate location inside the gas storage container 1301 for monitoring the real-time pressure and temperature inside the gas storage container 1301 to ensure that its operating status is within a set range.

[0076] In some embodiments, the predetermined location may also include a high-pressure inlet and a high-pressure outlet of the gas storage container 1301, used to detect dynamic pressure changes when the gas enters and exits the gas storage container 1301, to determine whether the gas delivery is smooth and whether there is a leakage problem in the sensor cleaning system.

[0077] In some embodiments, the predetermined location may also include the air inlet and air outlet of the air pump 120, for monitoring the operating efficiency of the air pump 120 and whether there are any abnormalities in the gas during the compression process.

[0078] Furthermore, the control circuit 1404 intelligently regulates the operating status of the gas source device 100 by using operating parameters such as pressure and temperature obtained from the sensor module, combined with its built-in logic algorithm. Specifically, the control circuit 1404 receives information output from the sensor module in real time. For example, when the pressure inside the gas storage container 1301 is lower than a preset threshold, the control circuit 1404 will start the air pump 120 to supplement compression; when the pressure exceeds the set value, the control circuit 1404 will trigger a pressure relief function or stop the air pump 120 to prevent overpressure from occurring.

[0079] Furthermore, based on the pressure data of the gas outlet 1102, the control circuit 1404 can adjust the operating parameters of the output pressure regulating device 1302 to ensure that the gas output to the sensor cleaning system is always maintained within the target pressure range, thereby improving the efficiency and stability of the sensor cleaning system.

[0080] Furthermore, the control circuit 1404 uses data from the sensor module to determine whether the gas source device 100 needs heating or cooling during operation. For example, in a low-temperature environment, the control circuit 1404 can activate the heating function to maintain the normal operating temperature of the air pump 120 and the air storage container 1301; in a high-temperature environment, it can activate the cooling function to prevent the gas source device 100 from overheating.

[0081] Furthermore, the sensor module can detect abnormalities in the operation of the gas source device 100, such as pipeline leaks, decreased efficiency of the air pump 120, and excessively high or low temperatures. The control circuit 1404 analyzes this data and executes corresponding protective measures, including stopping operation, issuing alarms, or switching to backup logic.

[0082] In this way, through real-time data acquisition and logic control, the sensor cleaning system can automatically adjust the working state of the air pump 120 and the output pressure of the air storage container 1301 according to operational needs, reducing manual intervention and improving the operating efficiency of the sensor cleaning system. The sensor module covers multiple predetermined locations, enabling comprehensive pressure and temperature monitoring to ensure the accuracy and reliability of the sensor cleaning system. The control circuit 1404 can dynamically adjust the operating state of the air pump 120 according to actual needs, avoiding energy consumption while improving gas output efficiency.

[0083] During sensor cleaning, the control circuit 1404 automatically adjusts the air supply output based on the external environment and the operating status of the air supply device 100, ensuring efficient completion of the cleaning task. Furthermore, the control component 140 can adapt to diverse needs in complex industrial environments, adjusting air supply parameters in real time to provide stable and reliable power support for industrial equipment. In extreme environments such as low temperature, high temperature, or high pressure, the control component 140 ensures stable operation of the air supply device 100 by controlling temperature and pressure.

[0084] In some embodiments, the sensor module includes a temperature sensor 1401 and a pressure sensor 1402, which are respectively arranged at multiple predetermined positions in the gas source device 100 for real-time detection of temperature and pressure data and transmission to the control component 140 for analysis and processing, thereby realizing efficient management and intelligent control of the gas source device 100.

[0085] Furthermore, the temperature sensor 1401 is arranged at predetermined positions in the gas source device 100, such as the gas inlet 1101 and gas outlet 1102 of the housing, the interior of the gas storage container 1301, the high-pressure inlet and high-pressure outlet, the inlet and outlet of the air pump 120, etc.

[0086] Temperature sensor 1401 is used to detect the real-time temperature value at a predetermined location to ensure that all parts of the gas source device 100 operate within a safe temperature range. For example, the temperature data at the air inlet of air pump 120 can reflect changes in ambient temperature, while the temperature data inside the gas storage container 1301 can indicate whether overheating occurs during the gas storage process.

[0087] Temperature data collected by temperature sensor 1401 can be transmitted to control circuit 1404 in real time. When an abnormal temperature is detected (such as too high or too low), control circuit 1404 can automatically trigger corresponding protection measures, such as starting heating function, heat dissipation function, or suspending the operation of air source device 100, thereby improving the safety of sensor cleaning system.

[0088] In low-temperature environments, the detection results of temperature sensor 1401 can be used to trigger the heating function of air pump 120 and air storage container 1301 to avoid the decrease in efficiency of sensor cleaning system due to low temperature; in high-temperature environments, the temperature of sensor cleaning system can be reduced through heat dissipation function to ensure stable operation of air source device 100.

[0089] Furthermore, the pressure sensor 1402 is also arranged in a predetermined position in the gas source device 100, such as the gas inlet 1101 and gas outlet 1102 of the housing, the inside of the gas storage container 1301, the high-pressure inlet and high-pressure outlet, the inlet and outlet of the air pump 120, etc.

[0090] Pressure sensor 1402 is used to detect the pressure status of various parts within the gas source device 100. For example, the internal pressure of the gas storage container 1301 can reflect whether the gas storage capacity is normal; the pressure of the gas outlet 1102 works in conjunction with the output pressure regulating device 1302 to ensure that the output pressure meets the usage requirements of the sensor cleaning system.

[0091] When the pressure sensor 1402 detects abnormal pressure (such as overpressure or underpressure), the control circuit 1404 can respond quickly, for example, by triggering a pressure relief function to release excess gas when the pressure is too high, or by starting the air pump 120 to supplement the pressure when it is insufficient, to ensure that the sensor cleaning system operates within a safe range.

[0092] By cooperating with multiple pressure sensors 1402 at predetermined locations, the control circuit 1404 can monitor the pressure difference within the gas source device 100 and dynamically adjust the output pressure. For example, by analyzing the pressure data from the high-pressure inlet and outlet, the gas storage and release process of the gas storage container 1301 can be improved, reducing energy loss.

[0093] By working in concert with temperature sensor 1401 and pressure sensor 1402, comprehensive status monitoring of the gas source device 100 can be achieved. For example, under high-temperature conditions, if pressure sensor 1402 detects an increase in internal pressure of the gas storage container 1301, control circuit 1404 can analyze the temperature and pressure data together to determine whether to trigger a heat dissipation function or a pressure relief function to avoid pressure overload caused by high temperature. Simultaneously, in low-temperature environments, the detection data from temperature sensor 1401 can be used to determine whether to trigger a heating function to improve the working efficiency of air pump 120, thereby ensuring the normal operation of the gas source device 100.

[0094] In some embodiments, the control component 140 further includes a pressure switch 1403. The pressure switch 1403 is used to monitor the pressure state at a predetermined location and to connect a specific circuit when the pressure exceeds a predetermined threshold, thereby triggering a corresponding control operation.

[0095] Furthermore, the pressure switch 1403 can be arranged in multiple predetermined locations on the gas source device 100, such as the gas inlet 1101 and gas outlet 1102 of the housing, the interior of the gas storage container 1301, the high-pressure inlet and high-pressure outlet, and the inlet and outlet of the air pump 120. The position of the pressure switch 1403 can be adjusted according to specific usage requirements to monitor the pressure status of different parts of the gas source device 100.

[0096] When pressure switch 1403 detects that the pressure at a predetermined location exceeds a predetermined threshold, pressure switch 1403 automatically connects a specific circuit, such as triggering a pressure relief function to release excess gas, thereby preventing damage to the gas source device 100 due to overpressure. In addition, pressure switch 1403 can also shut down the operation of air pump 120 to avoid further increasing the pressure of the sensor cleaning system.

[0097] By working in conjunction with the pressure sensor 1402, the pressure switch 1403 can provide multiple protection mechanisms for the gas source device 100. When the pressure sensor 1402 detects an abnormality but fails to provide timely feedback, the mechanical triggering characteristic of the pressure switch 1403 can serve as a redundant protection measure to ensure the safety of the sensor cleaning system. For example, when the pressure at the high-pressure outlet exceeds a predetermined threshold and is not released in time through the pressure relief device 191, the pressure switch 1403 can directly trigger the physical pressure relief function for protection.

[0098] In some embodiments, the gas source device 100 further includes a control interface 150. This control interface 150 is coupled to the control component 140 and is designed to provide communication connectivity to external devices to enable monitoring, operation, and parameter configuration of the gas source device 100. At least some of the functions of the control circuit 1404 mentioned above may also optionally be implemented via external devices connected through the control interface 150.

[0099] Furthermore, the control interface 150 is located outside the housing of the gas source device 100, facilitating the connection and operation of external devices. Its form can be a standardized electrical interface 180, such as a CAN bus interface, LIN bus interface, Flexray bus interface, IIC interface, RS232 / 485 interface for digital signals, and an I / O interface for analog signals or hardware switches. In addition, the control interface 150 may also include an Ethernet interface or other communication protocol interfaces to adapt to different scenarios and the needs of the gas source device 100. Furthermore, the control and diagnostic methods of the gas source device 100 also include I / O drive methods, such as low-side drive, high-side drive, PWM drive, HSD drive, etc., which are not specifically limited in the embodiments of this disclosure.

[0100] Furthermore, the control interface 150 enables bidirectional communication between external devices and the control component 140 of the gas source device 100. External devices can obtain real-time operating status information of the gas source device 100 through the control interface 150, such as the pressure and temperature of the gas storage container 1301, the operating status of the air pump 120, and output pressure parameters. Simultaneously, the control interface 150 also supports external devices sending operation commands to the control component 140, such as adjusting the output pressure, starting or stopping the air pump 120, and triggering the pressure relief function.

[0101] External devices can configure the operating parameters of the gas source device 100 through the control interface 150. For example, the maximum working pressure of the gas storage container 1301, the output pressure range, the pressure alarm threshold, and the temperature protection parameters can be set to meet the needs of specific application scenarios.

[0102] The control interface 150 can connect the gas source device 100 to the remote control system, enabling users to remotely monitor and control the gas source device 100 in real time.

[0103] When the gas source device 100 malfunctions, the control component 140 can transmit fault information to external devices via the control interface 150, prompting the user to perform inspection and maintenance. Furthermore, the control interface 150 is also used for remote troubleshooting, allowing users to directly perform parameter diagnosis and operation recovery via connected external devices.

[0104] In some embodiments, the gas source device 100 further includes a heating element 160 for implementing the heating function mentioned above. The heating element 160 is electrically coupled to the control component 140 and is used to heat the pressurized gas storage component 130 when the temperature is detected to be below a predetermined threshold, so as to ensure that the gas source device 100 can operate normally and efficiently in low-temperature environments.

[0105] Furthermore, the heating element 160 can be arranged around the pressurized gas storage assembly 130 or integrated inside the housing, and its form can be an electric heating element, a heating film, a heating tube, or other suitable heating device. Optionally, the heating element 160 is thermally coupled to predetermined positions of the air inlet and outlet of the air pump 120 and the high-pressure air inlet and high-pressure air outlet of the gas storage container 1301 to improve heating efficiency.

[0106] The control component 140 monitors the temperature of the air pump 120, the air storage container 1301, and related pipelines in real time via the temperature sensor 1401. When the detected temperature is lower than a predetermined threshold, the control component 140 issues a heating command to start the heating element 160.

[0107] After receiving a control signal, the heating component 160 heats the air or component surface around the air pump 120 and the air storage container 1301, thereby preventing the gas from freezing or becoming viscous due to low temperature, and ensuring the flowability of the gas and the operational stability of the system.

[0108] The control component 140 uses a closed-loop control algorithm and combines the feedback information from the temperature sensor 1401 to dynamically adjust the heating power of the heating component 160, so that the temperature of the gas source device 100 is maintained within the normal operating range, avoiding overheating damage to the gas source device 100 or wasting energy.

[0109] Furthermore, the heating element 160 enables the gas source device 100 to start and operate normally in low-temperature environments (such as -40°C to -85°C), thus improving the applicable environment of the gas source device 100.

[0110] The heating element 160 can prevent the gas from freezing in low-temperature environments or the gas source device 100 from mechanically jamming due to excessively low temperatures, thereby ensuring the safety and durability of the air pump 120 and the gas storage container 1301.

[0111] The start-up and power output of the heating element 160 are precisely controlled based on real-time temperature data, and it only operates when necessary, effectively reducing energy consumption and improving the overall energy efficiency of the sensor cleaning system.

[0112] In some embodiments, the air source device 100 further includes a heat dissipation component 170. The heat dissipation component 170 is coupled to the control component 140 and the pressurized air storage component 130, and is adapted to dissipate heat from the above components during the operation of the air source device 100, so as to ensure the normal operating temperature of the air source device 100 and ensure its efficient and stable operation.

[0113] Furthermore, the heat dissipation component 170 may include a heat sink, a cooling fan, a heat pipe, a liquid cooling module, or other suitable heat dissipation devices. Optionally, the heat dissipation component 170 may be disposed on the external surface of the air pump 120 and the air storage container 1301, or may be in close contact with the control component 140 through a thermally conductive material, which helps to transfer and dissipate the heat generated during operation. Simultaneously, the heat dissipation component 170 may be integrated into the housing arrangement, with ventilation openings or heat dissipation channels provided on the housing to improve heat dissipation efficiency.

[0114] The control component 140 monitors the temperature of the air pump 120, the air storage container 1301, and the control component 140 itself in real time via the temperature sensor 1401. When the temperature exceeds a predetermined safety threshold, the control component 140 activates the heat dissipation component 170 to reduce the temperature of the air source device 100.

[0115] For example, a cooling fan or liquid cooling module operates under the drive of the control component 140 to quickly remove heat from high-temperature areas.

[0116] Heat is naturally dissipated through highly thermally conductive heat sinks or housing materials, requiring no additional energy consumption.

[0117] Furthermore, the activation and power output of the heat dissipation component 170 can be dynamically adjusted by the control component 140 based on temperature feedback data to achieve precise heat dissipation and avoid energy waste caused by excessive heat dissipation.

[0118] The heat dissipation component 170 can prevent the control component 140 and the pressurized gas storage component 130 from performance degradation, failure or damage due to overheating, thereby improving the reliability and service life of the gas source device 100.

[0119] In some embodiments, the gas source device 100 further includes an electrical interface 180. The electrical interface 180 is located outside the housing and coupled to the control component 140, the air pump 120, and the gas storage component 130. The electrical interface 180 is connected to at least an external power source to supply power to the control component 140 and the pressurized gas storage component 130, thereby ensuring the normal operation of the gas source device 100.

[0120] Furthermore, the electrical interface 180 can employ standardized connection methods, such as plug-in connectors, threaded connectors, or other quick-connect devices, to achieve efficient connection with external power systems. Optionally, the electrical interface 180 can be integrated with the housing through a sealed design to ensure the interface's waterproof and dustproof performance, adapting to various complex working environments.

[0121] Furthermore, the electrical interface 180 is compatible with various power supply methods, including DC power (such as 12V or 24V vehicle power) and AC power (such as 110V or 220V AC mains power). Optionally, the control component 140 can detect the input power type through the interface and automatically perform power supply adaptation.

[0122] The electrical interface 180 can work in conjunction with the control component 140 to achieve real-time monitoring and management of the power supply status. For example, when the external power supply voltage or current is abnormal, the control component 140 can cut off the power input through the electrical interface 180 to prevent damage to the gas source device 100 due to overvoltage or overcurrent.

[0123] In some embodiments, the pressurized gas storage assembly 130 further includes a drying device 1304. The drying device 1304 is arranged between the air pump 120 and the gas storage container 1301, and is used to dry the gas compressed by the air pump 120. The drying device 1304 may take the form of, but is not limited to, a gas-water separator or an air dryer 1304, thereby effectively removing moisture from the gas, ensuring the stability of the gas quality stored in the gas storage container 1301, and meeting the gas source requirements of the sensor cleaning system.

[0124] Furthermore, the drying device 1304 is connected via an air passage between the air outlet of the air pump 120 and the high-pressure air inlet of the air storage container 1301. Optionally, the drying device 1304 is arranged inside the housing, and combined with the housing's sealing structure, it prevents external moisture from entering the sensor cleaning system, further improving the drying effect. In addition, the drying device 1304 can be modularly arranged, which facilitates independent maintenance and replacement.

[0125] When air is compressed by the air pump 120, the compression process causes moisture to condense. An air-water separator can remove liquid moisture from the compressed gas through mechanical separation, gravity separation, or centrifugal separation.

[0126] In environments with high humidity, the water vapor content in the gas is high. The air drying device 1304 can use technologies such as adsorption drying, cooling drying, or chemical drying to further remove water vapor from the gas, ensuring that the gas entering the gas storage container 1301 is always dry.

[0127] The drying device 1304 may be equipped with an automatic drainage device 190 for periodically draining the separated moisture to prevent moisture accumulation from affecting the drying effect.

[0128] In this way, the drying device 1304 can remove moisture from the compressed gas, preventing moisture from corroding or damaging the inner wall of the gas storage container 1301 and downstream components, and ensuring the operational stability of the sensor cleaning system. The drying process reduces malfunctions of the gas source device 100 caused by moisture and extends the service life of the air pump 120, the gas storage container 1301, and other components.

[0129] In some embodiments, the gas source device 100 further includes a drainage device 190 and / or a pressure relief device 191 for draining moisture from the pressurized gas storage assembly 130 and for depressurizing when the internal pressure of the pressurized gas storage assembly 130 is higher than a predetermined threshold, so as to ensure the normal operation and safety of the gas source device 100.

[0130] Furthermore, the drainage device 190 is coupled to the air passage between the pressurized gas storage components 130 to efficiently drain the moisture generated in the gas source device 100 due to gas compression.

[0131] In some embodiments, the drainage device 190 can monitor the accumulation of moisture through an automatic control system, and automatically open the drainage valve to drain water when the moisture reaches a predetermined level, so as to avoid moisture affecting gas quality or causing component corrosion.

[0132] Optionally, the drainage device 190 can also be set to a manual operation mode, which helps users to drain water as needed during maintenance.

[0133] The drainage device 190 is connected to the outside via an integrated drainage channel, which can effectively guide the discharged water to a designated location.

[0134] In some embodiments, the pressure relief device 191 is coupled to the internal pipeline of the pressurized gas storage assembly 130 to release excess pressure when the pressure of the pressurized gas storage assembly 130 exceeds a predetermined threshold, thereby ensuring the safe operation of the gas source device 100.

[0135] The pressure relief device 191 is connected to the pressure sensor 1402 via the control component 140. When the gas source device 100 detects that the pressure of the air pump 120 or the air storage container 1301 exceeds a predetermined threshold, it automatically triggers the pressure relief valve to release the excess pressure, thereby preventing the gas source device 100 from malfunctioning or becoming dangerous due to excessive pressure.

[0136] Optionally, the pressure relief device 191 can be set to a manual operation mode, allowing the user to perform manual pressure relief operations as needed, especially during maintenance or emergencies.

[0137] In some embodiments, the gas source device 100 further includes a quick-connect connector 192. The quick-connect connector 192 is arranged at the gas outlet 1102 for connecting to an external gas pipeline, which significantly improves the adaptability and operational efficiency of the gas source device 100.

[0138] Furthermore, the quick-connect coupling 192 can adopt a modular structure, consisting of a connector, a seal, and a locking mechanism. Specifically, the connector of the quick-connect coupling 192 is designed with standardized dimensions to accommodate gas pipelines of various outer diameters, helping users flexibly select external pipelines according to actual needs. The connector is equipped with a high-performance seal, ensuring reliable sealing during gas output, preventing gas leakage, and improving the energy efficiency of the gas source device 100. The quick-connect coupling 192 is equipped with a convenient locking mechanism, allowing for quick connection and disconnection of gas pipelines with one-handed operation, reducing installation and maintenance time costs.

[0139] The quick-connect connector 192 makes the gas supply device 100 particularly suitable for applications requiring frequent connection and disconnection. For example, in automotive sensor cleaning systems, the quick-connect connector 192 facilitates rapid replacement or adjustment of external gas lines; in industrial automation equipment, the high compatibility and ease of operation of the quick-connect connector 192 can adapt to various complex piping connection requirements. Furthermore, in medical devices, the quick-connect connector 192 enables rapid deployment, improving the response efficiency of the gas supply device 100.

[0140] In some embodiments, the gas source device 100 further includes a gas filter component 193. The filter component is detachably coupled to the gas inlet 1101 and is used to filter the gas entering the gas source device 100, remove impurities and particulate matter from the air, thereby improving the operating efficiency and stability of the gas source device 100 and ensuring that internal components are not contaminated.

[0141] Furthermore, the gas filtration component 193 can adopt a modular structure. The gas filtration component 193 includes a filter housing, a filter element, a sealing structure, and a quick-release mechanism. Furthermore, the filter housing can be made of a robust and durable material, capable of withstanding operation under high pressure environments and providing protection for the filter element. The filter element is housed inside the filter housing, and its materials include fiber mesh, activated carbon filter cartridges, or multi-layer composite material filter cartridges. Elements with different filtration precisions can be selected according to actual needs to adapt to different application scenarios.

[0142] Furthermore, the connection between the gas filter component 193 and the gas inlet 1101 is equipped with a sealing structure to ensure that gas can completely pass through the filter element without bypass leakage. Furthermore, the gas filter component 193 is connected to the gas inlet 1101 via a quick-release mechanism, ensuring quick installation and removal by the user, which facilitates maintenance or replacement of the filter element.
