BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 、 Figure 3 and Figure 4 This is a schematic structural diagram of a vehicle-mounted system for a heat dissipation system of an on-board camera in an embodiment;

[0039] Figure 2 Schematic diagram of the installation of a heat dissipation system for a vehicle-mounted camera in an embodiment. DETAILED DESCRIPTION

[0040] In this embodiment, the structure of the heat dissipation system for the vehicle-mounted camera is as follows: Figure 1 As shown. Figure 1 The heat dissipation system for the vehicle-mounted camera includes a power supply module and an active heat dissipation module; wherein the power supply module is used to supply power to the outside, and the active heat dissipation module is used to receive power from the power supply module and perform active heat dissipation on the vehicle-mounted camera.

[0041] In this embodiment, the vehicle-mounted camera can be Figure 2 As shown, it is installed on the front windshield, near the rearview mirror inside the car, and can be Figure 2 As shown, the heat dissipation system for the vehicle-mounted camera is installed on the vehicle-mounted camera to dissipate heat for the vehicle-mounted camera.

[0042] In this embodiment, the vehicle-mounted camera may also be installed on a rear windshield, a roof, or an engine compartment.

[0043] Specifically, the power supply module can be connected to a power source such as a car's battery, thereby obtaining electrical energy from the car's battery, performing voltage conversion and other processing, and then supplying power to the active heat dissipation module.

[0044] In this embodiment, the active heat dissipation module is a component with active heat dissipation capabilities. Active heat dissipation is the opposite of passive heat dissipation. Passive heat dissipation is a heat dissipation process that does not actively perform certain actions, but relies solely on the component's inherent properties to exchange heat through natural phenomena such as convection or radiation. For example, a heat sink is a typical passive heat dissipation component. Active heat dissipation, on the other hand, consumes a certain amount of energy to perform certain actions, thereby enhancing natural phenomena such as convection or radiation to exchange heat. For example, cooling fans and semiconductor coolers are both active heat dissipation components.

[0045] In this embodiment, a semiconductor cooler can be used as an active heat dissipation module. The semiconductor cooler is divided into a cold end and a hot end. When using the semiconductor cooler as an active heat dissipation module, the cold end of the semiconductor cooler can be connected to the housing or lens, CMOS, and other components that need to be cooled, while the hot end of the semiconductor cooler is exposed to the outside air. In this way, when the semiconductor cooler is powered on, the temperature of the cold end of the semiconductor cooler can be reduced, while the temperature of the hot end of the semiconductor cooler can be increased. In other words, the cold end of the semiconductor cooler absorbs heat, transfers it to the hot end, and dissipates it into the air, thereby dissipating heat from the housing, lens, CMOS, and other components of the vehicle camera.

[0046] The heat dissipation intensity of the active cooling module can be measured by calculating the amount of heat removed from the vehicle camera by the active cooling module per unit time. The heat dissipation intensity of the semiconductor cooler can be adjusted by adjusting the current. For example, the greater the current flowing through the semiconductor cooler, the greater the heat dissipation intensity of the semiconductor cooler.

[0047] In this embodiment, a cooling fan can be used as an active heat dissipation module. An air duct can be provided within the housing of the vehicle-mounted camera. The air duct can pass through components that require cooling, such as the lens and CMOS. The cooling fan is installed at the inlet or outlet of the air duct. When the cooling fan rotates, an airflow is generated in the air duct. The airflow flows through the housing of the vehicle-mounted camera or components that require cooling, such as the lens and CMOS, thereby dissipating heat from the entire vehicle-mounted camera or components such as the lens and CMOS.

[0048] In this embodiment, by providing an active heat dissipation module, the heat dissipation speed of the vehicle-mounted camera as a whole or some of its components can be improved, which is conducive to timely removing the heat generated by the vehicle-mounted camera's own operation and the heat received by the vehicle-mounted camera due to factors such as sunlight exposure, thereby helping to maintain the vehicle-mounted camera at a lower temperature, reduce the aging speed of components in the vehicle-mounted camera, and increase the service life of the vehicle-mounted camera. It can also keep the vehicle-mounted camera at a lower temperature to ensure the stability of the vehicle-mounted camera's imaging and shooting operations.

[0049] In this embodiment, the power supply module is a light power supply module. The light power supply module is used to receive ambient light energy and convert it into electrical energy to provide external power. For example, a solar cell can be used as the light power supply module. When the solar cell is illuminated by sunlight, it can convert the sunlight energy into electrical energy, thereby powering the active heat dissipation module, allowing the active heat dissipation module to actively dissipate heat from the vehicle-mounted camera.

[0050] In this embodiment, when the active heat dissipation module is powered by a solar power supply module, the solar power supply module does not need to be connected to a power source such as a car's battery, and can only rely on the conversion of light energy to power the active heat dissipation module, thereby reducing the burden on the car's power supply. In addition, when the car's power supply is damaged or the power storage is insufficient, the active heat dissipation module can also be guaranteed to work.

[0051] In this embodiment, refer to Figure 2 Since the solar power supply module can be installed at the same position as the vehicle-mounted camera, using the solar power supply module to power the active heat dissipation module can not only save energy and ensure the operation of the active heat dissipation module, but also when the vehicle-mounted camera is heated by sunlight and has a greater heat dissipation demand, the solar power supply module is also exposed to sunlight and supplies power to the active heat dissipation module, so that the active heat dissipation module actively dissipates heat for the vehicle-mounted camera, thereby meeting the greater heat dissipation demand of the vehicle-mounted camera.

[0052] In this embodiment, refer to Figure 3 The cooling system for the vehicle-mounted camera also includes a control module and an active cooling module. Among them, the control module is a component with functions such as data acquisition, processing, output and control.

[0053] In this embodiment, the control module can obtain the vehicle operating parameters, generate heat dissipation control instructions based on the vehicle operating parameters, and send the heat dissipation control instructions to the active heat dissipation module, so that the active heat dissipation module responds to the control of the heat dissipation control instructions and performs active heat dissipation on the vehicle-mounted camera.

[0054] Specifically, the vehicle operating parameters are parameters related to the vehicle's operating state, or the environment in which the vehicle operates. That is, the vehicle operating parameters can be used to describe the vehicle's operating state, or the environment in which the vehicle operates.

[0055] In this embodiment, by setting up a control module, the active heat dissipation module can be controlled, so that the active heat dissipation module actively dissipates heat for the vehicle-mounted camera under controllable conditions, and the heat dissipation control instructions are generated based on the operating parameters of the vehicle. Therefore, the active heat dissipation module actively dissipates heat for the vehicle-mounted camera, which can meet the heat dissipation requirements of the vehicle's working state or the environmental conditions in which the vehicle is located, and realize efficient utilization of the electrical energy output by the power supply module.

[0056] In this embodiment, refer to Figure 4 The cooling system for the vehicle-mounted camera is equipped with a temperature sensing module. The temperature sensing module is used to detect temperature information and send it to the control module as the vehicle's operating parameter.

[0057] Specifically, the temperature sensing module can detect the environment in which the vehicle-mounted camera is located (generally inside the car's cabin) and obtain temperature information, that is, the temperature information can represent the ambient temperature of the environment in which the vehicle-mounted camera is located; the temperature sensing module can also detect the temperature of the vehicle-mounted camera itself and obtain temperature information, that is, the temperature information can represent the temperature of the vehicle-mounted camera affected by the environment and the heat generated by its own work.

[0058] By setting up a temperature sensor module, the control module can call the temperature sensor module to detect temperature information, use the temperature information as the vehicle operating parameter, and generate heat dissipation control instructions based on this. In this case, when the control module generates the heat dissipation control instructions based on the vehicle operating parameters, it can specifically perform the following steps:

[0059] S1A. Set temperature threshold;

[0060] S2A. When the temperature information is greater than the temperature threshold, determining the heat dissipation intensity of the active heat dissipation module;

[0061] S3A. Generate a heat dissipation control instruction according to the heat dissipation intensity of the active heat dissipation module.

[0062] In step S1A, the control module can set different temperatures based on the type of temperature information detected by the temperature sensor module. For example, if the temperature information detected by the temperature sensor module is the ambient temperature, a lower value (such as 30°C) can be set as the temperature threshold; if the temperature information detected by the temperature sensor module is the temperature of the vehicle camera itself, a higher value (such as 60°C) can be set as the temperature threshold.

[0063] In step S2A, the control module does not generate a heat dissipation control instruction if the temperature information is less than or equal to the temperature threshold. If the temperature information is greater than the temperature threshold, the heat dissipation intensity is positively correlated with the difference between the temperature information and the temperature threshold.

[0064] Among them, if a semiconductor cooler is used as an active heat dissipation module, then the heat dissipation intensity of the active heat dissipation module can be controlled by the size of the power supply current. Therefore, when executing step S2A, if the difference between the temperature information and the temperature threshold is greater, then a larger power supply current is set; if a cooling fan is used as an active heat dissipation module, then the heat dissipation intensity of the active heat dissipation module can be controlled by the fan speed. Usually, the fan speed can be controlled by controlling the duty cycle of the power supply current. Therefore, when executing step S2A, if the difference between the temperature information and the temperature threshold is greater, then a larger power supply current duty cycle is set.

[0065] In step S3A, a corresponding heat dissipation control instruction is generated according to the power supply current size or the power supply current duty cycle size set in step S2A, and the heat dissipation control instruction is sent to the active heat dissipation module, so that the active heat dissipation module actively dissipates heat for the vehicle-mounted camera under the drive of the power supply current of the corresponding size or the power supply current of the corresponding duty cycle size.

[0066] In this embodiment, by executing steps S1A-S3A, when the ambient temperature or the temperature of the vehicle-mounted camera itself is greater than the temperature threshold (indicating that the ambient temperature or the temperature of the vehicle-mounted camera itself is too high), the active heat dissipation module can be started to perform active heat dissipation, and the higher the ambient temperature or the temperature of the vehicle-mounted camera itself, the stronger the heat dissipation intensity, thereby effectively meeting the heat dissipation requirements of the vehicle-mounted camera, avoiding excessive active heat dissipation, and reducing the waste of electricity on the power supply module.

[0067] In this embodiment, refer to Figure 4 The heat dissipation system for the vehicle-mounted camera is provided with a positioning module. The positioning module is used to locate the vehicle, obtain positioning information, and use the positioning information as the vehicle working parameter and send it to the control module.

[0068] Specifically, the positioning module may be a satellite positioning and navigation component.

[0069] By setting up a positioning module, the control module can call the positioning module to locate the car and obtain positioning information, where the positioning information can be in the form of longitude and latitude coordinates. The control module uses the positioning information as the car's operating parameters and generates heat dissipation control instructions based on it. In this case, when the control module generates heat dissipation control instructions based on the car's operating parameters, it can specifically perform the following steps:

[0070] S1B. Get the target location list;

[0071] S2B. When the positioning information approaches at least one target location in the target location list, a heat dissipation control instruction is generated according to the target location.

[0072] In this embodiment, the target location list can be stored locally by the control module, or stored in a cloud server or other location and dynamically updated. The target location list includes multiple target locations, which can be locations with a high demand for vehicle-mounted cameras, such as accident-prone locations identified by relevant agencies or multiple drivers, or locations where no public video surveillance cameras are installed.

[0073] When executing step S1B, the control module may read the target location list from a local or cloud server.

[0074] In step S2B, the control module may compare each target location in the target location list with the positioning information one by one.

[0075] Specifically, the control module can calculate the distance between each target position and the positioning information respectively. If it is detected that the distance between a target position and the positioning information is less than a distance threshold (for example, 1 km), and the positioning information is dynamically updated, and the distance between the positioning information and this target position gradually becomes smaller, then it can be determined that the positioning information is tending towards this target position.

[0076] In step S2B, if the control module does not detect that the positioning information is trending towards any target position, the control module may not generate a heat dissipation control instruction.

[0077] In step S2B, if the control module detects that the positioning information tends to a certain target position, then the control module can detect the distance between the positioning information and the target position, determine the corresponding heat dissipation intensity based on this distance, for example, the smaller the distance, the stronger the heat dissipation intensity, and generate a heat dissipation control instruction of the corresponding heat dissipation intensity.

[0078] In step S2B, if the control module detects that the positioning information is trending towards multiple target locations, the control module may detect the distances between the positioning information and each target location, and determine the corresponding heat dissipation intensity according to the minimum distance.

[0079] In this embodiment, by executing steps S1B-S2B, when the car reaches or approaches a location where the demand for the vehicle-mounted camera is relatively high, a heat dissipation control instruction can be generated to start the active heat dissipation module to actively dissipate heat for the vehicle-mounted camera, thereby improving the heat dissipation effect of the vehicle-mounted camera in advance, which is conducive to accelerating the cooling of the vehicle-mounted camera to a suitable temperature range. When the car reaches the target location, the vehicle-mounted camera can work normally to meet the demand for vehicle-mounted camera shooting and evidence collection in accident-prone areas or monitoring blind spots.

[0080] In this embodiment, when the control module obtains the vehicle operating parameters and generates the heat dissipation control instructions according to the vehicle operating parameters, it may further perform the following steps:

[0081] S1C. Obtain the image information captured by the vehicle camera;

[0082] S2C. Perform image recognition on the screen information and use the image recognition results as the vehicle operating parameters;

[0083] S3C. Generate heat dissipation control instructions based on the image recognition results.

[0084] In step S1C, the control module can connect to the vehicle-mounted camera and obtain authorization from the vehicle-mounted camera to obtain image information captured by the vehicle-mounted camera. The image information can be a still image or a dynamic video.

[0085] In step S2C, the control module may use an image recognition algorithm to perform image recognition on the image information. Specifically, the image recognition algorithm may identify optical parameters (e.g., brightness, saturation, etc.) or other parameter data within the image information, or may perform artificial intelligence recognition on the image information. The control module uses the image recognition results as vehicle operating parameters, and then generates cooling control instructions based on the image recognition results when executing step S3C.

[0086] For example, when executing step S2C, the control module can identify the statistical value (such as the maximum value or average value) of the brightness of each pixel in the picture information as the result of image recognition. In step S3C, the control module can set a brightness threshold. If the brightness statistical value of the picture information is greater than the brightness threshold, the control module generates a heat dissipation control instruction, and the larger the brightness statistical value of the picture information, the stronger the heat dissipation intensity corresponding to the heat dissipation control instruction.

[0087] In this embodiment, by executing steps S1C-S3C, the image information captured by the vehicle-mounted camera can be called, thereby controlling the active heat dissipation module to actively dissipate heat for the vehicle-mounted camera; for example, the brightness of the image information captured by the vehicle-mounted camera can be used to control the active heat dissipation module to actively dissipate heat for the vehicle-mounted camera. Since the brightness of the image information usually indicates the intensity of sunlight exposure to the vehicle-mounted camera, the greater the brightness of the image information, the greater the intensity of sunlight exposure received by the vehicle-mounted camera, and the greater the heat dissipation demand of the vehicle-mounted camera, it is possible to complete the detection of the heat dissipation demand of the vehicle-mounted camera by using only the data collected by the vehicle-mounted camera itself without setting up other sensor devices.

[0088] In this embodiment, when the control module executes step S3C, that is, the step of generating a heat dissipation control instruction based on the image recognition result, the control module may specifically execute the following steps:

[0089] S301. Obtain traffic risk assessment value based on the image recognition results;

[0090] S302. Set traffic risk threshold;

[0091] S303. When the traffic risk assessment value is greater than the traffic risk threshold, the heat dissipation intensity of the active heat dissipation module is determined; the heat dissipation intensity is positively correlated with the difference between the traffic risk assessment value and the traffic risk threshold;

[0092] S304. Generate a heat dissipation control instruction according to the heat dissipation intensity of the active heat dissipation module.

[0093] In step S301, the control module may call upon a trained artificial intelligence model to perform image recognition on the image information. The artificial intelligence model may identify the degree of danger of the behavior of a person or vehicle contained in the image information. For example, if a vehicle in the image information changes lanes multiple times, the artificial intelligence model may perform image recognition on the image information, and the image recognition result obtained will correspond to a greater degree of danger.

[0094] The image recognition result obtained by executing step S301 carries semantic information and can represent the traffic risk faced by the vehicle contained in the image information, expressed as a traffic risk assessment value. In this embodiment, a larger traffic risk assessment value indicates a greater risk of a traffic accident faced by the vehicle as identified based on the image information.

[0095] In step S302, the control module sets a traffic risk threshold, which measures the magnitude of the traffic risk assessment value. For example, if the traffic risk assessment value is less than or equal to the traffic risk threshold, it indicates that the traffic risk assessment value is low and the risk of a traffic accident faced by the vehicle is negligible. If the traffic risk assessment value is greater than the traffic risk threshold, it indicates that the traffic risk assessment value is high and the risk of a traffic accident faced by the vehicle is high, requiring careful driving and preparation for measures to deal with traffic accidents.

[0096] If the control module determines that the traffic risk assessment value is greater than the traffic risk threshold, the control module executes step S303 to calculate the difference between the traffic risk assessment value and the traffic risk threshold. This difference positively correlates with the heat dissipation intensity of the active heat dissipation module. Specifically, the greater the difference between the traffic risk assessment value and the traffic risk threshold, the greater the heat dissipation intensity of the active heat dissipation module. The control module then executes step S304 to generate a heat dissipation control instruction based on the heat dissipation intensity determined in step S303.

[0097] In this embodiment, the principle of executing steps S301-S304 is that the traffic risk assessment value obtained by intelligently identifying the image information captured by the vehicle-mounted camera can quantitatively represent the risk of traffic accidents faced by the vehicle. When the risk of traffic accidents faced by the vehicle is relatively high, a heat dissipation control instruction can be generated to start the active heat dissipation module to actively dissipate heat for the vehicle-mounted camera, thereby improving the heat dissipation effect of the vehicle-mounted camera in advance, which is conducive to accelerating the cooling of the vehicle-mounted camera to a suitable temperature range. Once the car encounters a traffic accident, the vehicle-mounted camera can work normally to meet the needs of the vehicle-mounted camera for shooting and collecting evidence when a traffic accident occurs in this vehicle or other vehicles.

[0098] In this embodiment, refer to Figure 4 The heat dissipation system for the vehicle-mounted camera is also provided with a storage module, which includes a battery, wherein the battery can be a lead-acid battery or a lithium battery. The storage module is provided with a battery management system BMS (Battery Management System), which can detect whether there is residual electric energy in the power supply module. The residual electric energy is the total value of the electric energy converted from the light energy by the light energy power supply module, minus the electric energy consumed to power the active heat dissipation module. Therefore, if the residual electric energy is greater than 0, the residual electric energy is the electric energy remaining after the light energy power supply module converts the light energy into electric energy to power the active heat dissipation module; if the residual electric energy is less than 0, the residual electric energy is the electric energy that the active heat dissipation module needs to receive in order to perform active heat dissipation when it obtains power from the light energy power supply module.

[0099] In this embodiment, when the remaining power is greater than 0, the battery management system BMS charges the remaining power into the battery; when the remaining power is less than 0, the battery management system BMS controls the battery to discharge to supplement power supply to the active heat dissipation module.

[0100] By setting up a storage module, when the light energy received by the solar power supply module is surplus, the excess electrical energy can be stored, and when the light energy received by the solar power supply module is insufficient, the excess electrical energy can be discharged for use by the active heat dissipation module, thereby ensuring that the active heat dissipation module works normally under various conditions.

[0101] In this embodiment, the heat dissipation system for the vehicle-mounted camera and the vehicle-mounted camera can be assembled into a whole for production and use, so that the vehicle-mounted camera can obtain active heat dissipation from the heat dissipation system.

[0102] A computer program for executing the heat dissipation system for a vehicle-mounted camera in this embodiment can be written and written into a computer device or storage medium. When the computer program is read out and run, the heat dissipation system for a vehicle-mounted camera in this embodiment is executed, thereby achieving the same technical effect as the heat dissipation system for a vehicle-mounted camera in the embodiment.
