Description

Technical Field

[0001] This application relates to the technical field of new energy vehicle charging, and particularly to an electric vehicle charging management system based on the Internet of Things. Background Art

[0002] New energy vehicles, mostly referring to electric vehicles in China, are different from fuel vehicles that operate with fuel. Instead, they use the charging method to supplement energy for work.

[0003] Currently, there are mainly two ways to supplement electric energy for electric vehicles: The first is battery swapping, that is, when the cruising range of an electric vehicle is low, the old battery is disassembled and replaced with a new high-capacity and fully charged battery pack; the second is charging, which is divided into fast charging and slow charging.

[0004] Relatively speaking, compared with the first method, the second method currently has a larger user group. In addition to charging at home, users can also use charging stations of major operators for charging. In order to provide a more comfortable charging experience for users, charging stations are often equipped with a charging service management system, which can not only guide users to solve problems encountered during the charging process, but also provide users with options such as charging methods.

[0005] However, the following situations in current charging stations are often difficult to solve: Some fuel vehicles, zombie vehicles, etc. will park their vehicles in the parking spaces corresponding to the charging piles, resulting in the inability of electric vehicles to charge. If it is feasible for the electric vehicle owners to actively contact the vehicle owners occupying the spaces, it is not very likely, because the time consumption and the possible risk of disputes in the middle will cause the electric vehicle owners to change their charging needs and locations; if an administrator is assigned to each charging station, in addition to considering the personnel salary, a workroom, etc. also need to be built. After all, it is impossible to let the administrator stay outdoors in summer and winter, resulting in too high continuous costs. Therefore, this application proposes a new technical solution.

[0023] The following further describes the present application in detail Figures 1-4 with reference to the attached

[0024] An embodiment of the present application discloses an electric vehicle charging management system based on the Internet of Things.

[0025] Refer to Figure 1 , the electric vehicle charging management system based on the Internet of Things includes a vision module and a site controller. Among them, the vision module includes several cameras, and the cameras are used to take pictures of the charging spaces; in this embodiment, the cameras are installed through the poles outside the charging piles, and the lenses are oriented towards the area where the charging spaces are located to collect video data. The site controller includes a switch and a supervision host, and the switch is connected to the cameras and the supervision host.

[0026] The above-mentioned supervision host is configured as follows: S11. Call the video data fed back by the cameras, process the video data (such as: decoding, segmentation, extracting frame images), and perform identification of charging space occupancy and charging behavior to obtain parking space usage information and whether charging information.

[0027] It can be understood that image recognition is an existing technology, and corresponding samples can be imported into the model for training, so it will not be elaborated here.

[0028] S12. If the vehicle on a certain parking space is not charging, that is, the charging gun is not in use, it is defined as a type-II vehicle, and a type-I vehicle is a charging vehicle; Start timing to obtain the non-charging holding duration t1 of any type-II vehicle.

[0029] S13. If the non-charging holding duration t1 of any type-II vehicle is greater than the preset trigger duration T1, for example: 15 - 30 minutes, then execute the abnormal occupancy supervision process.

[0030] The above-mentioned abnormal occupancy supervision process includes: S21. If the non-charging holding duration t1 is less than the first interval duration T2, then obtain the license plate number of the corresponding vehicle, and send a vehicle relocation reminder message to the vehicle owner according to the license plate number; where T2 > T1, it can be 2 - 4 hours, for example: The above-mentioned cameras capture the vehicle image with the license plate, identify the license plate number, request the contact number of the vehicle owner corresponding to the license plate number from the pre-connected relevant department system through the license plate number, and send a reminder message to the vehicle owner by text message. The reminder can be 5 - 15 minutes / time.

[0031] S22. If T2 ≤ t1 < t3, then request to access the automatic vehicle relocation system preset in the charging station, send the position of the matching type-II vehicle, and send a vehicle relocation in progress reminder to the vehicle owner; where t3 is the trigger duration for automatic vehicle relocation.

[0032] According to the above settings, when a non-charging vehicle occupies a charging space for a long time, this application can send a prompt message to the corresponding vehicle owner, and use the automatic vehicle relocation system to relocate the vehicle after the prompt is not resolved by the vehicle owner in time, thereby reducing the occupation of charging spaces by non-charging vehicles and improving the charging service experience of the charging station.

[0033] In another embodiment of this system, considering that the camera on the charging stand pole may sometimes not be able to capture the image with the license plate due to obstacles such as vehicles, further, the logic for the supervision host to obtain the license plate number of the corresponding vehicle includes: S31. Determine the time H1 when the target Class II vehicle parks in the charging space, that is, the time when the vehicle appears in the charging space; S32. Calculate the time H1 and the preset on-site driving reference duration t4 to estimate the moment t5 when the vehicle enters the parking lot; Example: The time H1 when a Class II vehicle appears in a certain charging space is 14:30, and the preset on-site driving reference duration t4 is 5 - 8 minutes, then the estimated moment t5 when the vehicle enters the parking lot is 14:22 - 14:25.

[0034] S33. Based on the moment t5, request to call the access data of the access management system of the parking lot where the charging station is located at the corresponding moment; among them, the access data at least includes the image data captured at the corresponding time.

[0035] S34. Compare the access data with the data of the target Class II vehicle obtained by the camera, lock the target Class II vehicle in the access data, and read the corresponding license plate number.

[0036] Example: The image captured by the charging pile shows that the target vehicle is a red SUV, then find the red SUV in the access data and read the corresponding license plate number; more precisely, compare the vehicle's external contour, wheels, and visible features on the front, rear, left, and right sides.

[0037] According to the above settings, this system can determine the information of the target vehicle with the help of the access management system (i.e., the barrier gate) of the parking lot where the charging station is located, reducing the defect caused by the obstruction of the camera line of sight near the charging pile; at the same time, this design ensures that the installation position of the camera of the existing charging station does not need to be changed, improving the cost performance of the solution.

[0038] During the above process, the moment t5 is required. In this embodiment, it is considered that if the on-site driving reference duration t4 is a fixed range value, it is easy to cause the system to be unable to effectively identify the target vehicle, because the sizes of different parking lots are different, and even if driving at the same speed, the on-site driving reference duration t4 will also be different; moreover, there may be random situations such as temporary roadblocks in the parking lot, so this system makes the following settings: S41. Use T3 as the sampling interval duration, and randomly call a vehicle that has most recently entered a parking space as the target vehicle; where t3 is less than 24 hours. S42. Use the time when the target vehicle parked in the parking space as the starting time for backward search. S43. Call the access data of the access management system of the parking lot where the charging station is located at the backward search starting time and previous times, and compare it with the image data of the target vehicle until the target vehicle appears in the access data and record the corresponding time as the entry time. Example: Randomly call the parking time of a vehicle that has most recently entered any parking space, that is, the starting time for backward search is 9:50. Call the access data of the access management system of the parking lot where the charging station is located before 9:50. Through vehicle comparison, when the target vehicle appears in the access data, record the entry time, assuming it is 9:38.

[0039] S44. Calculate the actual reference duration t6 based on the backward search starting time and the entry time. It can be understood that according to the above example, based on the backward search starting time of 9:50 and the entry time of 9:38, the actual reference duration t6 can be calculated to be 12 minutes.

[0040] S45. If the difference between the actual reference duration t6 and the in-parking lot driving reference duration t4 exceeds the preset allowable fluctuation range, then calculate the actual reference duration t6 with a new target vehicle continuously N times. It can be understood that the allowable fluctuation range is set to, for example, 2 minutes. According to the above example, the actual reference duration t6 is 12 minutes, and the in-parking lot driving reference duration t4 is 5 - 8 minutes, that is, the difference between the two exceeds 2 minutes; then calculate the corresponding actual reference duration t6 with a new target vehicle continuously N times.

[0041] S46. If the differences between the actual reference durations t6 for N consecutive times and the in-parking lot driving reference duration t4 all exceed the allowable fluctuation range, then use the average value of the actual reference durations t6 for N consecutive times as the new in-parking lot driving reference duration t4; where N can be 2 - 4.

[0042] According to the above settings, when this system is used, only the initial value needs to be set as t4 at the very beginning, and then the system can continuously self-check and dynamically adjust according to the actual situation during use to ensure that the subsequent in-parking lot driving reference duration t4 relatively conforms to the actual situation of the parking lot and ensure the accuracy of locking the target vehicle.

[0043] Refer to Figure 2 And Figure 3, in another embodiment of the present application, the automatic vehicle relocation system includes a support structure 1, a jacking mechanism 2, and a mobile trolley 3; among them, multiple groups of support structures 1 are provided, and each group is respectively disposed on the ground of each parking space. The support structure 1 includes a support platform 11 erected on the parking space. The support platform 11 is fixedly connected with feet 12 that make it suspended from the ground. The entrance end of the support platform 11 is fixedly connected with a ramp 13 that facilitates the entry and exit of vehicles. Thus, when the vehicle drives into the parking space, it drives onto the support platform 11 through the ramp 13. In order to prevent the vehicle tires from slipping on the support platform 11 and causing the support platform 11 to move when the vehicle drives onto the support platform 11, a stop block 14 is fixedly installed on the parking space. The stop block 14 is located between the two feet 12, and the feet 12 can be limited by the stop block 14 and will not move greatly, enabling the vehicle to park more smoothly on the support platform 11.

[0044] The jacking mechanism 2 is located below the support platform 11 and is fixed to the mobile trolley 3. Since the support platform 11 is suspended above the parking space ground through the feet 12, the mobile trolley 3 can drive the jacking mechanism 2 to move under the support platform 11, cross each parking space, and jack up the support platform 11 through the jacking mechanism 2, so that the support platform 11 lifts the vehicle. It should be noted that due to the installation of the stop block 14, the lowermost end of the feet 12 of the support platform 11 is lifted to at least a position higher than the uppermost end of the stop block 14, and then the mobile trolley 3 drives the jacking mechanism 2 out of the parking space, thereby moving the Class II vehicle out of the charging parking space. In this embodiment, the jacking mechanism 2 adopts a prior art hydraulic scissor lift, that is, the scissor lift link structure is driven by a hydraulic system to achieve jacking, so it will not be elaborated here.

[0045] Refer to Figure 4 , among which, the mobile trolley 3 includes a mobile seat 31, a power system 32 installed in the mobile seat 31, a wireless communication unit, a positioning unit, and a battery module; in this embodiment, the wireless communication unit can be a 4G / 5G module, and the positioning unit can be a positioning chip. The power system 32 will be elaborated below.

[0046] The site controller is respectively connected to the power system 32, the wireless communication unit, the positioning unit, and the jacking mechanism 2 through data and is configured as: 1), based on the position information of the target Class II vehicle and the vehicle entry and exit conditions of the vehicles near the target Class II vehicle obtained by the camera, control the power system 32 to drive the jacking mechanism 2 to move across each support structure 1 to below the target Class II vehicle, and then control the power system 32 to turn the mobile seat 31; It can be understood that the control power system 32 moves the mobile cart 3 to the position of the target Class II vehicle. At this time, the mobile cart 3 is located below the target Class II vehicle. According to the video data captured by the camera, the vehicle entry and exit and the movement of people in the parking spaces near the target Class II vehicle are analyzed. When it is determined that there are no vehicles or people moving near the parking spaces, the mobile cart 3 is controlled to turn (because the mobile cart 3 crosses each parking space, that is, the forward direction of the mobile cart 3 is perpendicular to the entry and exit direction of the parking space. If the vehicle is to be moved out of the parking space, the forward direction of the mobile cart 3 needs to be adjusted so that the forward direction of the mobile cart 3 is consistent with the entry and exit direction of the parking space).

[0047] 2) If a signal is received from the power system 32 after the steering is completed, the lifting mechanism 2 is controlled to perform the lifting action; It can be understood that the lifting mechanism 2 lifts the support platform 11 upward to lift the vehicle.

[0048] 3) If a feedback signal is received from the lifting mechanism 2 after the lifting action is completed, the power system 32 is controlled to execute the vehicle moving out action.

[0049] It is understandable that the mobile cart 3 drives the support platform 11 to move out, and then the vehicle is moved out of the parking space. Then the mobile cart 3 drives the second type of vehicle to turn 90 degrees to facilitate other charging vehicles to enter the parking space. In addition, the jacking mechanism 2 can also be controlled to lower the support platform 11. Since the support platform 11 is provided with a support foot 12 at the bottom, it can be supported on the ground by the support foot 12. It should be noted that since the mobile cart 3 crosses each parking space, obstacles such as green grass that hinder the movement of the mobile cart 3 should not be set between the parking spaces in the same row of the parking lot of the charging station. Secondly, if there are vehicles parked in the same row of parking spaces, a separate ground space should be set at the end of the same row of parking spaces for the mobile cart 3 to move out of this row of parking spaces, so that the mobile cart 3 can be moved to other rows of parking spaces when needed.

[0050] Since the mobile vehicle 3 needs to turn on the spot, the power system 32 includes four wheels rotatably mounted on the mobile seat 31 and four motors for driving each vehicle to rotate independently, and the motors are electrically connected to the site controller.

[0051] Through the above settings, the torque, speed and direction of the four motors can be controlled respectively, so that the speeds of the four wheels are coordinated, thereby achieving in-situ turning of the mobile car 3 with the center as the center of the circle.

[0052] In order to facilitate dealing with emergencies, the mobile car 3 is also equipped with a remote control, which is controlled by the charging station manager. The remote control is equipped with main buttons such as up, down, left, right, and one-button turn button, so that the manager can also directly control the movement and turn of the mobile car 3 through the remote control.

[0053] In another embodiment of the present application, considering that after moving a Class II vehicle out of the parking space, it should not obstruct the vehicles in the nearby parking spaces, further, the site controller is further configured to: After the power system 32 executes the vehicle removal action, call the video data fed back by the camera to obtain the position data of the adjacent parking spaces of the removed Class II vehicle; Based on the adjacent parking space position data, search the preset database to determine the corresponding parking space number, and call the charging order corresponding to the parking space number from the charging station charging system connected in advance; Based on the charging order, analyze the estimated vehicle charging completion time and estimate the shifting and avoiding moment of the mobile trolley 3; Based on the shifting and avoiding moment, send a shifting and avoiding control instruction to the power system 32.

[0054] Exemplary: The database prestores the position data of each parking space in the parking lot and the corresponding parking space numbers. For example, the parking space number of the first parking space in the first row is 1-101, and the parking space number of the first parking space in the second row is 2-101. According to the position of the mobile trolley 3 and the video data collected by the camera, by searching the database, the adjacent parking space numbers are obtained. For example, if the mobile trolley 3 moves out a Class II vehicle located at 1-104, then the removed Class II vehicle is outside this parking space, so the adjacent parking space numbers are 1-103 and 1-105 respectively.

[0055] According to the parking space number, call the corresponding charging order from the charging station charging system, analyze the charging progress according to the charging order, obtain the estimated charging completion time, and use this time as the shifting and avoiding moment of the mobile trolley 3; The shifting and avoiding control instruction can be to control the power system 32 to move the mobile trolley 3 2m in the direction away from the parking space where charging is completed, so as to facilitate the vehicle that has completed charging in the adjacent parking space to drive out of the parking space.

[0056] In another embodiment of the present application, considering that there will be individual vehicle owners who are in emergency charging temporarily and will not wait until the vehicle is fully charged before leaving, but will settle the charging in advance. Therefore, the site controller is further configured to: If a charging completion settlement instruction fed back by the charging station charging system is received, obtain the location of the vehicle; Judge and analyze whether the location of the vehicle is in the adjacent parking space of the removed Class II vehicle. If so, send a shifting and avoiding control instruction to the power system 32.

[0057] It can be understood that the charging completion settlement instruction can be a charging completion settlement interface, which includes the parking space number where the vehicle is located. According to the parking space number, the location of the vehicle can be known. Through the video data fed back by the intervention camera, since the Class II vehicle being removed is parked horizontally outside the parking space, it is possible to judge whether the vehicle that has completed charging is located in the adjacent parking space of the removed Class II vehicle through the picture taken by the camera. If so, a displacement avoidance control instruction is sent to the power system 32; In another embodiment of the present application, in order to prevent the mobile trolley 3 from colliding during the vehicle moving process, the following is set: The site controller is data-connected to ranging sensors. There are four ranging sensors, which are respectively fixedly installed at the four corner positions of the moving seat 31. The detection heads of the ranging sensors face the outside of the moving seat 31. The site controller is configured as: If the mobile trolley 3 is in the moving process, obtain the distance detection value fed back by the ranging sensors; If the distance detection value exceeds the preset collision warning range value, control the power system 32 to stop responding until the distance detection value meets the preset safe movement condition. Among them, the collision warning range value can be 1m, and the safe movement condition can be greater than 1m.

[0058] Example: When the ranging sensor detects that the distance detection value from the obstacle is 0.5, the mobile trolley 3 stops moving until the distance detection value is greater than 1m, then the mobile trolley 3 resumes responding.

[0059] In another embodiment of the present application, in order to facilitate charging the battery module of the mobile trolley 3, the mobile trolley 3 further includes a wireless charging module for charging the battery module. The wireless charging module includes a transmitting unit and a receiving unit. The transmitting unit is installed on the ground of the parking space, and the receiving unit is installed at the bottom of the moving seat 31 and is electrically connected to the battery module; in order to save resources, the transmitting unit does not need to be installed on the ground of each parking space, and only needs to be installed on the ground of specific parking spaces. When the mobile trolley 3 needs to be charged, it moves to the parking space equipped with the transmitting unit for wireless charging.

[0060] In this embodiment, the transmitting unit includes a power supply circuit and a transmitting coil, and the receiving unit includes a receiving coil, a rectifying and voltage stabilizing circuit, and a communication module for communicating with the transmitting unit. The above all adopt the existing technology to realize the wireless charging technology, so it will not be elaborated here.

[0061] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
