Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging, and in particular to an intelligent charging safety monitoring system. Background Art

[0002] At present, most parking lots are equipped with charging piles for electric vehicles, and car owners can use the charging piles to charge their vehicles when parking their vehicles in the parking lots. However, the existing charging method generally requires car owners to park their vehicles, get off the car and scan the identification code on the charging pile or use the touch screen on the charging pile to enter a specified interface. In the specified interface, car owners need to manually enter the vehicle's license plate number, charging pile information and other information to bind the vehicle and the charging pile on the parking space, so that the cost calculation and other steps can be performed after the subsequent charging is completed.

[0003] However, the method of manually inputting the vehicle license plate number is inefficient; if the license plate number is to be automatically recognized, a camera is generally installed at the entrance of the parking lot, but this method cannot know which parking space the vehicle is parked in; if a camera is installed on the side of each parking space to capture the license plate, the vehicle is likely to collide with the camera when entering the parking space; if a camera is installed on the top of each parking space, the camera cannot clearly capture the vehicle's license plate due to angle problems, resulting in failure to obtain the license plate number, which makes the user experience poor;

[0004] Moreover, after the vehicle is parked in the parking lot, the owner will generally leave the vehicle until the vehicle is fully charged. When the owner leaves, the owner cannot be informed of the safety issues of the vehicle in time, which poses certain risks. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide an intelligent charging safety monitoring system. The camera module can rotate the shooting angle to clearly capture the vehicle's license plate number. At the same time, the charging monitoring circuit monitors the charging process to provide users with a safe and convenient parking charging method.

[0006] The purpose of the present invention is achieved by the following technical solutions:

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0032] This embodiment provides an intelligent charging safety monitoring system to provide car owners with a convenient and safe parking and charging experience, thereby improving the user experience.

[0033] This system is mainly used in unmanned indoor and outdoor parking lots. A large parking lot can be divided into multiple parking areas 1. In this embodiment, a parking area 1 is a parking space, and each parking space is equipped with a set of intelligent charging safety monitoring system, so that the owner can know the parking and charging status of the vehicle at any time through the intelligent charging safety monitoring system. In addition, multiple parking spaces can be divided into a parking area 1, and a parking area 1 is equipped with a set of intelligent charging safety monitoring system to reduce equipment investment costs. The scope and size of the parking area 1 are not limited here.

[0034] like Figure 1 , Figure 2 As shown, the smart charging safety in this embodiment mainly includes three modules: camera assembly, main control circuit 7 and charging assembly. The camera assembly includes a sensing module 6, a rotating module 3 and a camera module 4. In this embodiment, each parking area 1 is equipped with a canopy 2, which can shield the vehicle from sunlight and rain, and the camera module 4 in this embodiment is installed on the side of the canopy 2 facing the top of the vehicle, so that the camera module 4 can fully capture the outer contour of the entire vehicle from a bird's-eye view, and can also capture the surroundings of the vehicle. The camera module 4 is installed under the canopy 2, which can shield part of the sunlight for the shooting module to improve the shooting quality.

[0035] The camera module 4 is fixed above the parking area 1 through the rotating module 3. In the present embodiment, the rotating module 3 can be set as a pan-tilt bracket, the fixed end of the pan-tilt bracket is fixed on the shelter 2, and the movable end is connected to the camera module 4, so that the camera module 4 can have a rotation function. In the present embodiment, the rotating module 3 is provided with a rotation angle of 180° in the horizontal direction parallel to the ground. In addition, the camera module 4 can also be set to have a rotation angle of 90° in the vertical direction perpendicular to the ground to increase the rotation range of the camera module 4.

[0036] Each parking area 1 is generally planned as a rectangular structure to fit the vehicle type, and generally has four sides. Generally, the vehicle can decide from which way or angle to enter the parking area 1 in combination with the local terrain and the parking situation of the vehicle next to the parking space. In this embodiment, a charging pile 5 is provided in the parking area 1. Since the charging pile 5 occupies a certain space, the vehicle generally does not enter from the side where the charging pile 5 is provided. The vehicle can enter the parking area 1 from the other three sides. A sensing module 6 can be provided on any side for the vehicle to enter, that is, the sensing module 6 is provided on the edge position for the vehicle to enter in each parking area 1. In this embodiment, the parking area 1 is planned to have a sensing module 6 provided on at least two vehicle entry edge lines. When the vehicle passes through any edge line and enters the parking area 1, the sensing module 6 can identify the direction of the vehicle entering the parking area 1. At this time, the rotation angle of the rotating module 3 can be determined according to the direction, so that the camera module 4 is rotated to an angle facing the entering vehicle to take a picture of the vehicle's license plate. Since the camera module 4 can be driven by the rotating module 3 to change its horizontal angle, and it has the ability to change its vertical angle, the camera module 4 can be flexibly rotated to improve its shooting accuracy.

[0037] The rotation angle of the rotating module 3 can be bound to the sensing module 6. For example, the fixed rotation angle of the rotating module 3 is preset when the sensing module 6 on each vehicle entering the edge line is triggered. When the next vehicle triggers any sensing module 6, the rotating module 3 can quickly rotate to the preset angle, reducing the burden of data processing and analysis and improving the rotation of the rotating module 3.

[0038] The sensing module 6 can be arranged in an infrared sensing device or a gravity sensing device. When a vehicle enters the parking area 1 and touches the vehicle entry edge line, the infrared light beam emitted by the infrared sensing device is blocked by the vehicle, and the vehicle's entry direction can be known at this time; or, when the vehicle enters the vehicle entry edge line of the parking area 1, the weight of the vehicle is recognized by the gravity sensing device located on the vehicle entry edge line, and the vehicle's entry direction can also be known.

[0039] The signal detected by the sensing module 6 can be sent to the main control circuit 7 , which is connected to the rotating module 3 . The main control circuit 7 determines the rotation direction and angle of the rotating module 3 according to the detection signal of the sensing module 6 .

[0040] When the infrared sensing device detects that the infrared light beam is converted from a blocked state to an unblocked state, or when the vehicle gravity detected by the gravity sensing device drops to a set weight, it can be considered that the vehicle has completely entered the parking area 1; wherein, it is possible that the vehicle has been pressing against the edge line when parking, making it impossible for the sensing module 6 to accurately identify whether the vehicle has completely entered the parking area 1. Therefore, when the charging pile 5 in the parking area 1 starts working, it can also be considered that the current vehicle has been parked in the parking area 1.

[0041] When the vehicle has parked in the parking area 1, the main control circuit 7 controls the rotating module 3 to automatically restore its rotation angle, and at the same time controls the camera module 4 to rotate to an angle overlooking the roof of the vehicle. At this time, the camera module 4 can be used to capture a panoramic image of the vehicle.

[0042] Among them, the main control circuit 7 is connected to a license plate image processing module and a panoramic image processing module. The license plate image processing module is used to analyze and process the license plate image taken by the camera module 4 to obtain the license plate number; and the panoramic image processing module is used to correct the overhead view of the vehicle taken by the camera module 4 through an algorithm to obtain images around the vehicle in all directions to prevent illegal elements from damaging the vehicle.

[0043] In addition, the main control circuit 7 is connected to a wireless communication module, and the main control circuit 7 is connected to the terminal via the wireless communication module, wherein the terminal may be a vehicle-mounted display screen, a mobile phone terminal, a tablet computer, or a touch display screen provided on the charging pile 5, etc. The terminal may enter the designated interface by scanning the QR code in the parking area 1 or logging into the APP, mini program, etc. During the scanning process, the terminal automatically obtains the unique identification code and address of the parking area 1, etc., and automatically obtains the license plate number photographed by the camera module 4 in the parking area 1 when the vehicle enters the parking area 1 through the unique identification code of the parking area 1, and at the same time obtains the user's identity information, and binds the user information, the vehicle's license plate number, and the parking area 1; the user can view the charging billing information through the APP or mini program software on the terminal, complete the fee payment in the software, and obtain the vehicle pictures taken by the current camera module 4, etc., so that the user can understand the vehicle status at any time after leaving the vehicle.

[0044] In addition, the software can obtain the geographic location of parking area 1 through the unique identification code of parking area 1, and at the same time obtain the current GPS positioning address of the terminal, and then plan the vehicle pick-up route from the terminal to parking area 1 in combination with the map, so that users can quickly find the parking location of the vehicle according to the map navigation, thereby improving the user experience.

[0045] The charging pile 5 in the parking area 1 is connected to a charging monitoring circuit 8, and the charging monitoring circuit 8 is connected to the main control circuit 7 by signal. Figure 3As shown, the charging monitoring circuit 8 at least includes a voltage acquisition unit 801, a temperature detection unit 802, a charging management unit 803 and a protection unit 804; wherein the voltage acquisition unit 801 is connected to the output end of the charging pile 5 to collect the voltage signal output by the vehicle charging; the temperature detection unit 802 is connected to the output end of the charging pile 5 to collect the charging temperature; the charging management unit 803 is connected to the voltage acquisition unit 801 and the temperature detection unit 802 to monitor the voltage parameters and temperature parameters during the charging process in real time, and compare them with the preset normal range values. If the normal range values ​​are exceeded, it is defined as an abnormal situation; and the protection unit 804 is connected to the charging management unit 803 and the output end of the charging pile 5. When the monitoring result of the charging management unit 803 is abnormal, the output end of the charging pile 5 is controlled to be disconnected to avoid damage to the vehicle battery to ensure the safety of charging.

[0046] At the same time, the parameters monitored by the charging monitoring circuit 8 are sent to the terminal for display through the wireless communication module of the main control circuit 7, so that the owner can check the charging status of the vehicle at any time on the software APP.

[0047] In this embodiment, the charging pile 5 in the parking area 1 can be connected to a photovoltaic charging device, which can be laid flat on the upper surface of the shade shed 2 to fully collect outdoor sunlight. A storage battery is provided in the charging pile 5. The photovoltaic charging device collects solar energy and converts it into electrical energy and stores it in the energy storage battery, thereby achieving the effect of energy saving and consumption reduction.

[0048] When the vehicle is fully charged or needs to leave the parking area 1, the user can press the button to leave the parking area 1 in the software, or use the camera module 4 to capture a picture of no vehicle parked in the parking area 1 within a preset time period, or the sensing module 6 detects that the vehicle that has entered the parking area 1 has completely left the parking area 1, the main control circuit 7 automatically starts the reset function, and uploads all the parameters obtained in the previous parking cycle, such as the monitored parameters and the photos taken by the camera module 4, to the cloud, clears the parameters from the local, and restores the angle of the rotating module 3; the camera module 4 can also be controlled to be in a dormant state, and the camera module 4 is activated to start shooting only when the next vehicle triggers the sensing module 6, thereby reducing energy consumption.

[0049] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
