Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a method, device, equipment and medium for preventing dust from entering a charging pile. Background Art

[0002] With the gradual popularization of new energy vehicles, new energy charging piles have also gradually become popular. Charging piles will generate a lot of heat during the charging process, so they are generally equipped with a cooling system. The most commonly used cooling system is the air cooling system, which works by configuring air inlets and outlets on the charging piles to exchange heat.

[0003] However, in actual use, due to the dust in the environment, the air inlet and outlet will carry dust into the charging pile during heat exchange. If a large amount of dust enters the charging pile, it will affect the heat dissipation and normal operation of the charging pile.

[0004] The existing technology uses dust-proof nets at the air inlet and outlet of the charging pile to prevent dust from entering the charging pile. The dust-proof nets have different dust-proof levels. The higher the dust-proof level, the better the dust-proof effect. However, the dust-proof nets with high dust-proof levels will affect the air cooling effect, thereby affecting the charging power; the dust-proof nets with low dust-proof levels have poor dust protection effects, thereby affecting the heat dissipation and normal operation of the charging pile.

[0031] Embodiment 1

[0032] Figure 1A flowchart of a charging pile dust prevention method is provided for the first embodiment of the present invention. This embodiment is applicable to the case where the dust prevention level of the dustproof net of the charging pile is determined. The method can be performed by a charging pile dust prevention device, which can be implemented in the form of hardware and / or software. The charging pile dust prevention device can be configured in a module with computing capabilities in the charging pile. Figure 1 As shown, the method includes:

[0033] S110: Determine a dust-generating parking space associated with a target charging pile, and obtain parking space information and vehicle information of the dust-generating parking space.

[0034] Among them, the associated dust parking space refers to the parking space in the area where the dust will affect the target charging pile. For example, the associated dust parking space can be the charging parking space of the target charging pile or the adjacent parking space. Parking space information refers to the relevant information that affects the dust prevention effect of the target charging pile in the parking space, such as the distance between the target charging pile and the associated dust parking space. The closer the associated dust parking space is to the target charging pile, the greater the impact of the dust on the associated dust parking space on the dust prevention effect of the target charging pile. Vehicle information refers to information related to the vehicle parked in the associated dust parking space and affects the amount of dust in the parking space, such as the speed information of the vehicle. The greater the speed of the vehicle parked in the parking space, the greater the amount of dust.

[0035] Specifically, all candidate parking spaces in the parking area where the target charging pile is located are determined, and the associated dust parking space is selected from the candidate parking spaces according to the degree of influence of the dust on the candidate parking space on the target charging pile. The real-time image of the associated dust parking space is obtained through the image acquisition device deployed in the parking area, and the parking space information of the associated dust parking space and the vehicle information of the parked vehicle are determined through the image recognition result. Exemplarily, the real-time image of the associated dust parking space is obtained according to the image acquisition device on the target charging pile. Since the acquisition field of view of the image acquisition device on the target charging pile is limited, the corresponding relationship between the candidate charging pile and the candidate parking space is established in advance according to the image acquisition field of view of all candidate charging piles in the parking area where the target charging pile is located, that is, the candidate charging pile can acquire the real-time image of the candidate parking space with the corresponding relationship. After determining the associated dust parking space of the target charging pile, the corresponding associated charging pile is determined according to the information of the associated dust parking space, and the parking space information and vehicle information of the associated dust parking space are obtained through the associated charging pile, and sent to the target charging pile, or the associated charging pile directly sends the collected image of the associated dust parking space to the target charging pile.

[0036] Exemplarily, the parking space information and vehicle information of the associated dust parking spaces are obtained, and the parking space information and vehicle information of all associated dust parking spaces corresponding to the target charging pile are saved by defining the matrix AroundParkingSpaceArray, AroundParkingSpaceArray=[ParkingSpaceInfo1,…,ParkingSpaceInfom], ParkingSpaceInfom represents the parking space information and vehicle information of the mth associated dust parking space, and each ParkingSpaceInfo structure is defined as follows: ParkingSpaceInfo={DistanceLevel,VehicleSizeLevel, VehicleSpeedLevel}, DistanceLevel represents the parking space information, VehicleSizeLevel and VehicleSpeedLevel represent the vehicle information.

[0037] In a feasible embodiment, determining the dust-generating parking space associated with the target charging pile includes:

[0038] Determine the distance between each candidate parking space and the target charging pile in the parking area where the target charging pile is located;

[0039] If the distance between the target parking space and the target charging pile is less than a preset distance threshold, the target parking space is determined to be an associated dust parking space.

[0040] Since the farther the dust area is from the target charging pile, the smaller the impact of the dust in the area on the target charging pile, the associated dust parking space is determined according to the distance between each candidate parking space and the target charging pile.

[0041] Specifically, all parking spaces around the target charging pile in the parking area are determined as candidate parking spaces, the distance between the center position of the candidate parking space and the target charging pile is determined, and the candidate parking spaces with a distance less than a preset distance threshold are used as associated dust parking spaces.

[0042] S120: Determine the parking space dust intensity of the associated dust parking space according to the parking space information and vehicle information of the associated dust parking space.

[0043] Since the parking space information and vehicle information of the associated dust-generating parking space are information that affects the dust effect on the target charging pile, the parking space dust intensity of the associated dust-generating parking space is determined according to the impact level of the parking space information and vehicle information on the dust effect on the target charging pile, wherein the parking space dust intensity is used to characterize the amount of dust that affects the target charging pile in the associated dust-generating parking space, and the greater the parking space dust intensity, the greater the amount of dust that affects the target charging pile in the associated dust-generating parking space.

[0044] Exemplarily, the direction of the impact of parking space information and vehicle information on the amount of dust is determined. For example, if the parking space information is the distance between the associated dust-generating parking space and the target charging pile, the greater the distance, the smaller the amount of dust affecting the target charging pile; if the vehicle information is the speed of the vehicle parked in the associated dust-generating parking space, the greater the speed, the greater the amount of dust affecting the target charging pile. The relationship between the parking space information and vehicle information and the parking space dust intensity is determined based on the impact direction. The parking space information and the parking space dust intensity are negatively correlated, and the vehicle information and the parking space dust intensity are positively correlated. Based on this relationship, the relationship between the parking space information, the vehicle information and the parking space dust intensity is determined. For example, the parking space information and vehicle information of the associated dust-generating parking space are digitized, and the values ​​are normalized. The inverse of the parking space information and the addition of the vehicle information are used as the parking space dust intensity of the associated dust-generating parking space; or, the inverse of the parking space information of the associated dust-generating parking space and the weighted sum of the vehicle information are used as the parking space dust intensity of the associated dust-generating parking space, and the weights of the parking space information and the vehicle information can be determined based on the actual impact on the amount of dust.

[0045] In a feasible embodiment, the parking space information includes a distance parameter associated with the dust-generating parking space and the target charging pile; the vehicle information includes a vehicle size parameter and a vehicle speed parameter associated with the dust-generating parking space;

[0046] Accordingly, the parking space dust intensity of the associated dust-generating parking space is determined according to the parking space information and vehicle information of the associated dust-generating parking space, including:

[0047] The parking space dust intensity of the associated dust parking space is determined according to the distance parameter, the vehicle size parameter and the vehicle speed parameter.

[0048] Among them, the distance parameter between the associated dust parking space and the target charging pile is used to characterize the distance between the associated dust parking space and the target charging pile, the vehicle size parameter on the associated dust parking space is used to characterize the size of the vehicle parked on the associated dust parking space, and the vehicle speed parameter on the associated dust parking space is used to characterize the speed of the vehicle parked on the associated dust parking space.

[0049] Specifically, the distance between the associated dust-generating parking space and the target charging pile is determined according to the position information of the associated dust-generating parking space and the position information of the target charging pile, and the vehicle size and vehicle speed of the vehicle parked in the associated dust-generating parking space are determined by an image acquisition device; since the distance, vehicle size and vehicle speed are not in the same order of magnitude, the distance, vehicle size and vehicle speed are normalized and the influencing direction is made consistent to obtain distance parameters, vehicle size parameters and vehicle speed parameters, so that the distance parameters, vehicle size parameters and vehicle speed parameters have the same order of magnitude and the same direction of influencing the amount of dust, that is, the larger the distance parameters, vehicle size parameters and vehicle speed parameters are, the greater the influence on the amount of dust is, that is, they are positively correlated with the dust intensity of the parking space.

[0050] Exemplarily, the distance parameter is DistanceLevel, which defines three levels: greater than 5 meters, within 5 meters, and within 1 meter, corresponding to values ​​of the distance parameter of 1-3.

[0051] The vehicle size parameter is VehicleSizeLevel, which defines three levels according to small car, medium car, and large car, and the corresponding vehicle size parameter values ​​are 1-3.

[0052] The vehicle speed parameter is VehicleSpeedLevel, which is defined into three levels: slow (less than 0.5 m / s), medium (less than 1 m / s), and fast (greater than 1 m / s). The corresponding vehicle speed parameter values ​​are 1-3.

[0053] Define DustRaisingLevel as the dust raising intensity of the associated dust-raising parking space. The larger the value of the dust raising intensity, the greater the dust, and the smaller the value, the less dust.

[0054] The calculation formula of DustRaisingLevel is as follows:

[0055] DustRaisingLevel=DistanceLevel*VehicleSizeLevel*VehicleSpeedLevel.

[0056] S130: Determine the dust intensity of the charging pile according to the dust intensity of the dust parking space associated with the target charging pile.

[0057] The parking space dust intensities of all associated dust-generating parking spaces corresponding to the target charging pile are determined respectively, and the total of the parking space dust intensities of all corresponding associated dust-generating parking spaces is taken as the charging pile dust intensity of the target charging pile.

[0058] Determining the dust intensity of the charging pile based on the dust intensity of the associated dust parking space can reflect the superposition result of all dust amounts around the target charging pile that can produce dust impact, thus ensuring the accuracy of the dust intensity of the charging pile.

[0059] Exemplarily, for a target charging pile, the parking space dust intensities of all associated dust-generating parking spaces within a preset distance threshold range are determined, and the sum of the parking space dust intensities of the target charging pile is obtained.

[0060] S140: Determine a target dust protection level from multiple dust protection levels according to the dust intensity of the charging pile, and switch the dust protection net of the target charging pile to the target dust protection level.

[0061] Since the charging pile is equipped with dustproof nets of various dustproof levels, the dustproof net of the lowest level is used when the charging pile is in the initial state. The higher the dustproof level, the better the dustproof effect of the dustproof net. For example, the charging pile can be equipped with dustproof nets of various dustproof levels by setting multiple different dustproof nets inside the charging pile, each dustproof net having a different dustproof level. When using the dustproof net of the target dustproof level, the dustproof nets of other dustproof levels are hidden.

[0062] In a feasible embodiment, the target dust prevention level is determined from a plurality of dust prevention levels according to the dust intensity of the charging pile, including:

[0063] Based on a pre-established relationship between the dust intensity and the dust protection level of the candidate charging piles, a target dust protection level is determined from the multiple dust protection levels according to the dust intensity of the charging piles; wherein the relationship between the dust intensity and the dust protection level of the charging piles is a positive correlation.

[0064] Among them, the dust intensity of the candidate charging pile is any one of the value ranges of the dust intensity of the charging pile, and the pre-established relationship between the dust intensity of the candidate charging pile and the dust prevention level can be represented by a mapping relationship, that is, the dust intensity of all candidate charging piles is divided into intervals to obtain multiple charging pile dust intensity intervals, and each charging pile dust intensity interval corresponds to a dust prevention level. Alternatively, the pre-established relationship between the dust intensity of the candidate charging pile and the dust prevention level can be represented by a functional relationship, and the specific functional relationship can be determined according to the numerical range of the dust intensity of the candidate charging pile and the numerical representation range of the dust prevention level, which is not limited here.

[0065] After determining the dust intensity of the charging pile, determine the target dust protection level that matches the dust intensity of the charging pile. The greater the dust intensity of the charging pile, the higher the matching target dust protection level. The dustproof net of the target dustproof level in the target charging pile is set at the heat dissipation port, and the dustproof net of the non-target dustproof level is hidden.

[0066] Exemplarily, an array of dustproof levels [L1,…,Ln] of the dustproof net is defined, and the dustproof levels from L1 to Ln increase in sequence. When the charging pile is initialized, the L1 level dustproof net is used by default. A relationship correspondence table RelationshipTable between the dust intensity of the charging pile and the dustproof level Ln is predefined. Each item in the RelationshipTable defines the correspondence between the dust intensity of the charging pile and the dustproof level. According to the current dust intensity of the target charging pile, the corresponding target dustproof level is obtained by looking up the relationship table RelationshipTable. According to the target dustproof level obtained from the table, the dustproof net of the target charging pile is switched to the corresponding level.

[0067] The dust prevention level of the target charging pile is switched according to the dust intensity of the charging pile, thereby realizing adaptive adjustment of the dust prevention level of the dust prevention net of the charging pile and improving the dust prevention effect of the target charging pile.

[0068] The technical solution of the embodiment of the present invention determines the parking dust intensity of each associated dust parking space through the relevant information of the associated dust parking spaces around the charging pile, and determines the charging pile dust intensity of the charging pile according to the parking space dust intensity, and then switches the dust protection level of the current charging pile dustproof net according to the charging pile dust intensity, thereby solving the problem that the dust protection level of the charging pile dustproof net affects the dust protection effect or heat dissipation effect due to inaccurate dust protection level, and effectively improves the dust protection effect of the charging pile while minimizing the impact on charging and heat dissipation.

[0069] Embodiment 2

[0070] Figure 2 This is a flow chart of a charging pile dust prevention method provided in the second embodiment of the present invention. This embodiment further refines the feature of periodically refreshing after determining the dust intensity of the charging pile in the above embodiment. Figure 2 As shown, the method includes:

[0071] S210: Determine a dust-generating parking space associated with a target charging pile, and obtain parking space information and vehicle information of the dust-generating parking space.

[0072] S220: Determine the parking space dust intensity of the associated dust parking space according to the parking space information and vehicle information of the associated dust parking space.

[0073] S230: Determine the dust intensity of the charging pile according to the dust intensity of the dust parking space associated with the target charging pile.

[0074] S240: Determine whether a dust intensity refresh cycle has been reached based on the time interval between the current time and the determination time of the dust intensity of the current charging pile.

[0075] Since the amount of dust on the associated dust parking space will change as the parked vehicle leaves, enters or remains parked, the dust intensity of the charging pile is periodically updated according to a predetermined dust intensity refresh cycle to ensure the dust-proof effect of the target charging pile dustproof net.

[0076] Specifically, a refresh interval, i.e., a dust intensity refresh cycle, is predetermined, the determination time of the dust intensity of each charging pile is recorded, and it is determined whether the time interval from the determination time of the current charging pile dust intensity to the current time is greater than or equal to the dust intensity refresh cycle.

[0077] S250: If reached, the parking space dust intensity of the associated dust parking space is updated according to the updated vehicle information on the associated dust parking space.

[0078] If the time interval between the current time and the determination time of the dust intensity of the current charging pile reaches the dust intensity refresh cycle, the vehicle information on the dust parking space associated with the target charging pile is re-acquired, and the parking space dust intensity of the associated dust parking space is updated according to the re-acquired real-time vehicle information.

[0079] For example, if the dust intensity refresh cycle is reached, real-time image information of the dust parking space associated with the target charging pile is obtained, the updated vehicle information is determined based on the real-time image information, and the parking space dust intensity of the associated dust parking space is updated based on the updated vehicle information. For example, the updated parking space dust intensity of the associated dust parking space is determined based on the updated vehicle information and the parking space information.

[0080] In a feasible embodiment, updating the parking space dust intensity of the associated dust parking space according to the updated vehicle information on the associated dust parking space includes:

[0081] Determine whether there is a moving vehicle in the associated dust-raising parking space according to the updated vehicle information in the associated dust-raising parking space;

[0082] If it does not exist, the parking space dust intensity is updated according to the dust degradation model; wherein, the parking space dust intensity in the dust degradation model is negatively correlated with time;

[0083] Otherwise, the parking space dust intensity is updated according to the parking space information of the associated dust parking space and the updated vehicle information.

[0084] When the associated dust-generating parking space generates dust of a certain intensity due to the movement of vehicles entering and exiting, if the vehicle in the associated dust-generating parking space stops or leaves, the dust in the parking space will gradually decrease over time. Therefore, in order to improve the accuracy of the parking space dust intensity update, it is necessary to combine the movement state of the vehicle in the associated dust-generating parking space. If the vehicle is in motion, a large amount of dust will be generated due to the movement of the vehicle, so the current dust intensity can be directly determined based on the current vehicle information of the vehicle; if the vehicle is not in motion, including the vehicle in the associated dust-generating parking space is stationary, and there is no parked vehicle in the associated dust-generating parking space, as long as the parking space dust intensity is determined in the previous dust intensity refresh cycle, the parking space dust intensity needs to be degraded and updated.

[0085] Specifically, the vehicle information on the associated dust parking space of the target charging pile is reacquired, and whether the vehicle on the associated dust parking space is in motion is determined based on the reacquired real-time vehicle information. If in motion, the parking space dust intensity of the parking space is re-determined based on the updated vehicle information and parking space information. Exemplarily, the updated vehicle information includes updated vehicle size parameters and updated vehicle speed parameters on the associated dust parking space, and the updated parking space dust intensity of the associated dust parking space is determined based on the distance parameter, the updated vehicle size parameter, and the updated vehicle speed parameter. If it is not in motion, it means that the associated dust parking space is not currently generating new dust, and it is only necessary to determine the degradation of the aforementioned dust. The degradation of the parking space dust intensity is determined based on a predetermined dust degradation model. For example, the parking space dust intensity is decreased at a preset time interval. The decrease amplitude can be determined based on the actual scenario and is not limited here.

[0086] In a feasible embodiment, the parking space dust intensity is updated according to the dust degradation model, including:

[0087] If the parking space dust intensity is greater than 0, the intensity reduction parameter is determined according to the preset dust degradation unit value and the dust degradation time unit; wherein the dust degradation time unit is determined according to the current time and the determination time of the parking space dust intensity;

[0088] The difference between the parking space dust intensity and the intensity reduction parameter is taken as the updated parking space dust intensity, and the degradation stops until the updated parking space dust intensity is equal to 0.

[0089] If there is no moving vehicle in the associated dust parking space, determine whether the dust intensity of the current parking space is greater than 0. If it is greater than 0, it is determined that a vehicle has generated dust in the parking space in the previous dust intensity refresh cycle, and since there is no moving vehicle to disturb the dust again, the dust in the parking space is in a state of gradually decreasing. The preset dust degradation unit value and dust degradation time unit refer to the dust intensity being reduced by the preset dust degradation unit value within the time corresponding to the dust degradation time unit. The specific values ​​of the preset dust degradation unit value and dust degradation time unit can be determined according to the actual scenario of the associated dust parking space, and are not limited here.

[0090] Specifically, the number of preset dust degradation unit values ​​corresponding to the time interval is determined according to the time interval between the current time and the determined time of the dust intensity of the parking space, the intensity reduction parameter is determined according to the product of the number of preset dust degradation unit values ​​and the dust degradation time unit, and the updated dust intensity of the parking space is obtained by subtracting the intensity reduction parameter from the dust intensity of the parking space. Subsequently, if there has been no moving vehicle in the parking space, the dust intensity of the parking space will continue to be reduced according to the dust degradation model until it is reduced to 0. If, during the reduction process, it is determined according to the updated vehicle information that there is a moving vehicle in the associated dust parking space, the updated dust intensity of the parking space is directly determined according to the updated vehicle information and the parking space information of the moving vehicle.

[0091] Exemplarily, the preset dust degradation unit value may be the same as the dust intensity refresh cycle, and the determination time of the parking space dust intensity is the same as the determination time of the charging pile dust intensity. If the parking space dust intensity is greater than 0, the difference between the parking space dust intensity and the preset dust degradation unit value is used as the updated parking space dust intensity, until the updated parking space dust intensity is equal to 0 and the degradation stops.

[0092] S260: Update the dust intensity of the charging pile according to the updated dust intensity of the parking space.

[0093] After the parking space dust intensities of all dust-generating parking spaces associated with the target charging pile are updated, the updated charging pile dust intensity is determined according to the sum of the updated parking space dust intensities.

[0094] S270: Determine a target dust protection level from multiple dust protection levels according to the updated dust intensity of the charging pile, and switch the dust protection net of the target charging pile to the target dust protection level.

[0095] In a feasible embodiment, after the dustproof net of the target charging pile is switched to the target dustproof level, the method further includes:

[0096] Get the temperature of the target charging pile;

[0097] If the temperature is greater than the preset temperature threshold, the charging power of the target charging pile is reduced;

[0098] If the dustproof level of the dustproof net of the target charging pile is reduced, the charging power is increased step by step according to the preset levels.

[0099] Due to the movement of vehicles in the associated dust-proof parking spaces around the target charging pile, the dust protection level of the switched dustproof net is increased. If the charging power of the target charging pile is too large at this time, the high dust protection level affects the heat dissipation, causing the temperature of the target charging pile to rise. The increase in temperature will further affect the charging effect of the charging pile and may cause damage to the charging pile.

[0100] Therefore, after increasing the dustproof level of the dustproof net of the target charging pile, the temperature of the target charging pile is monitored. If the temperature of the target charging pile is greater than the preset temperature threshold, the charging power of the target charging pile is reduced to reduce the temperature of the target charging pile. When the dustproof level of the dustproof net of the target charging pile is reduced, the charging power is restored step by step. For example, when the dustproof level of the dustproof net of the target charging pile is reduced, the preset power unit is increased on the basis of the current charging power, and the temperature of the target charging pile is continued to be monitored. If the temperature is reduced, the preset power unit is continued to be increased. In the subsequent process, when the dustproof level of the dustproof net of the target charging pile is reduced or the temperature is reduced, the preset power unit is continued to be increased until the normal charging power is restored.

[0101] The technical solution of the embodiment of the present invention periodically updates the dust intensity of the charging pile, and then periodically updates the dust prevention level of the target charging pile according to the periodically updated dust intensity of the charging pile, so as to improve the dust prevention effect and heat dissipation effect of the dustproof net of the target charging pile.

[0102] like Figure 3 The flowchart of another dust prevention method for charging piles is shown. When the target charging pile is initially used, the parking space dust intensity is initialized according to the parking space information and vehicle information of the associated dust parking space, and the initial charging pile dust intensity is obtained. The target dust prevention level is determined according to the initial charging pile dust intensity, and the dust prevention net of the target charging pile is switched from the initial level to the target dust prevention level; at the same time, it is determined whether the dust intensity refresh cycle is currently reached. If not, it continues to be judged according to the current time. If it is reached, all the associated dust parking spaces of the target charging pile are traversed, and the parking space dust intensity of each associated dust parking space is updated. When updating, it is updated according to whether there are vehicles in motion on each associated dust parking space. If there are vehicles in motion, the parking space dust intensity is directly updated according to the parking space information of the associated dust parking space and the updated vehicle information; if there are no vehicles in motion, the parking space dust intensity is updated according to the dust degradation model.

If the temperature is greater than the preset temperature threshold, the charging power of the target charging pile is reduced; if the dustproof level of the dustproof net of the target charging pile is reduced, the charging power is increased step by step according to the preset level.
