Description
Technical Field
[0001] The utility model relates to the technical field of charging piles, in particular to an AC charging pile for sensor recognition inspection and gun head awakening. Background Art
[0002] With the increasing popularity of electric vehicles, the demand for charging stations is growing. However, it's not uncommon for charging spaces to be occupied by non-electric vehicles, causing significant inconvenience for electric vehicle owners. This also increases the number of issues with re-plugging the charging station. During charging, a customer might decide they need to go out and stop charging on the app. Later, realizing they don't need to leave, they have to run downstairs or to the garage to re-plug the charging station, wasting considerable time and energy. Sometimes, misoperation can cause a vehicle to stop charging. A way to re-activate the charging station on the app would undoubtedly provide peace of mind for customers.
[0003] Therefore, it is necessary to provide a sensor recognition inspection and gun head awakening AC charging pile, which can not only improve the utilization efficiency of parking spaces, but also enhance the safety of management. Utility Model Content

[0007] A sensor-based AC charging station with inspection and head-activated waking technology has been developed. This intelligent solution aims to effectively address the challenges of occupied charging spaces and the need to re-insert charging heads. The core of this invention lies in the intelligent transformation of the charging station. First, it employs advanced sensor technology to monitor the charging station's usage status in real time. When a non-electric vehicle (such as a blue-plate gasoline vehicle) occupies the charging station, the sensor quickly identifies and records this activity. Simultaneously, the charging station's built-in high-performance processor rapidly analyzes the sensor data to determine whether the parking space has been illegally occupied. Once this is confirmed, the charging station activates a proactive feedback mechanism. AI-powered voice communication technology is used to alert the driver to vacate the space. The charging station's built-in speech synthesizer generates a voice message to notify the administrator of the occupied space and request intervention. In short, the application of smart cameras has revolutionized parking space management. It not only improves parking space efficiency but also enhances management security. The introduction of Sentry Mode and the Energy Efficiency Charging App further enhances intelligent and user-friendly parking space management. In addition, a switch is connected in series between the CC resistance detection point and the RC resistor, and then a long line is led from the switch to the PCB board and connected to the MCU main control chip. By controlling the switch, the car can re-detect the CC resistance value and thus wake up the gun head.
[0008] As a preferred improvement of the present invention: the information module is connected to the security management room of the parking lot where the charging pile is located.
[0009] As a preferred improvement of the present invention: the information module includes a 4G module, and the 4G module is connected to the user's mobile phone APP.

[0015] 1. When the smart camera identifies a blue-plate gasoline vehicle attempting to park in a new energy vehicle parking space, it automatically activates a voice announcement system to remind the vehicle owner that the space is reserved for new energy vehicles and to leave as soon as possible. This intelligent recognition and reminder function effectively avoids confusion in parking space usage due to misparking and improves parking space utilization.
[0016] 2. By controlling the switch, the car can re-detect the CC resistance value, thereby waking up the gun head. Charging can be turned on and off remotely, without the user having to run to the parking space to plug in and unplug the charging gun, which is convenient for users.

[0031] With the continuous advancement of technology, smart cameras have gradually become an indispensable part of our lives. Smart cameras are particularly important in parking space management. They not only monitor parking space usage in real time, but also recognize license plates and provide voice notifications and information for specific vehicle types, providing significant convenience for both drivers and parking administrators. Among the numerous parking spaces, some may be reserved for new energy vehicles or conventional gasoline vehicles. When a smart camera identifies a blue-plate gasoline vehicle attempting to park in a new energy space, it automatically activates a voice notification system to remind the driver that the space is reserved for new energy vehicles and to vacate it immediately. This intelligent recognition and reminder function effectively prevents parking space confusion caused by accidental parking and improves parking space utilization. Furthermore, smart cameras can transmit identified vehicle information to associated administrators (such as security guards), allowing them to monitor parking space usage in real time and promptly address any violations. This timely information transmission not only improves administrator efficiency but also enhances the security of parking space management. Notably, smart cameras also feature a sentry mode. In this mode, the camera provides 24 / 7 real-time monitoring of parking spaces, similar to factory surveillance footage. Whether day or night, sunny or rainy, the smart camera clearly captures every movement in the parking space. Car owners can check their parking status at any time through the mobile app to ensure vehicle safety.
[0032] A sensor recognition inspection and gun head wake-up AC charging pile product, which consists of the following components: a camera and voice integrated module (referred to as the integrated module), a gun head switch wake-up circuit, a radio frequency identification module, a reset button, a seven-hole national standard gun line, and a flame-retardant and purple-proof PC shell. It has the following functions: 1. It supports the use of a camera and voice integrated module to identify the parking or vacant status of several parking spaces managed by itself, and to identify the license plate information of parked vehicles. The camera uses image recognition and license plate recognition technology to determine the usage status of the managed parking spaces, as well as the license plate information when occupied, and feeds back to the bound manager's mobile phone, thereby prompting the owner to leave. 2. It supports the mobile phone App to re-awaken the gun head, so that after the gun is plugged in, the vehicle end will detect the CC value again to start charging.
[0033] In one embodiment, the information module is connected to the security management office of the parking lot where the charging pile is located. The information module includes a 4G module, which is connected to the user's mobile phone app. The charging pile body is provided with a flame-retardant and purple-proof PC shell, a radio frequency identification module, and an LED light. The mains power connection port is connected to a flyback converter and a charging gun. The flyback converter is connected to a buck step-down circuit and a CP circuit. The buck step-down circuit is connected to an LED light and an LDO step-down circuit. The LDO step-down circuit is connected to the controller MCU, the radio frequency identification module, the camera, and the voice module.
[0034] like Figure 2 As shown, AC mains power is fed into the AC charging pile through a residual leakage detection circuit. Once inside, it is split into two paths: one path is output to the charging cable connector via a relay; the other path, through a fuse and a varistor, serves as the input for an auxiliary power supply. This auxiliary power supply converts the mains power into DC voltages of 12V, -12V, 5V, or 3.3V to power the entire system, including the MCU circuit, pulse signal circuit, RFID (radio frequency identification) module, camera and voice integrated module, and switch detection circuit.
[0035] Camera Recognition: During the installation of a smart charging station, the owner must upload basic information about the charging station to the backend for binding. This information includes key data such as the charging station number, location, and power, facilitating subsequent management and monitoring. Once installation and binding are complete, the charging station establishes a stable connection with the backend system. When a blue-plate gasoline vehicle mistakenly parks in a charging space, the camera mounted above the space comes into play. The camera quickly recognizes the license plate information and, using a built-in algorithm, transmits the result to the charging station's microcontroller (MCU). The MCU, the "brain" of the charging station, is responsible for receiving and processing signals from the camera. After receiving the license plate information, the MCU not only transmits the information to the camera and voice integration module, but also transmits it to the backend system via the station's 4G network module. The 4G module plays a crucial role in this process, enabling real-time communication between the charging station and the backend, ensuring timely information transmission and processing. Once the voice integration module receives the information, it immediately initiates a voice announcement, reminding the owner of the misplaced vehicle to leave the charging space as soon as possible. This timely voice reminder can not only effectively prevent car owners from continuing to occupy charging parking spaces without knowing it, but also improve the management efficiency of the entire parking lot. At the same time, the background system is also nervously processing information from the charging piles. Through the background processing of the server, the information is accurately conveyed to the parking lot manager or security personnel. They can respond quickly based on this information and take necessary measures to ensure the normal use of charging parking spaces. The combination of smart charging piles and camera recognition systems not only improves the management efficiency of charging parking spaces, but also provides a more convenient and efficient charging experience for the majority of new energy vehicle owners. With the continuous advancement of technology and the expansion of application scenarios, I believe that this system will play a more important role in the future and promote the sustained and healthy development of the new energy vehicle industry. Such as Figure 3 shown.
[0036] Sentinel Mode: In the era of intelligent parking, the application of IoT technology is becoming increasingly widespread. Sentinel Mode, with its unique advantages, is playing an increasingly important role in smart parking space monitoring. Sentinel Mode uses a camera to capture images of parking spaces and transmits them to the flash chip of the parking MCU for storage. This information is then transmitted to the backend via the 4G network and ultimately presented to the parking owner via an app, enabling real-time and convenient access to parking space information. The operational process of Sentinel Mode embodies the sophistication and efficiency of the technology. First, a camera installed in the parking space acts as a sentry, constantly monitoring the status of the space. Whenever a vehicle enters or exits, the camera immediately captures the image and transmits it to the parking MCU via an internal communication protocol. The MCU, the "brain" of the parking space, not only receives and processes this information but also stores it in a flash chip to ensure data integrity and security. The MCU then connects to a backend server via its built-in 4G module and uploads the image information stored in the flash chip to the backend. During this process, the high-speed and stable transmission characteristics of the 4G network ensure the real-time and accuracy of this information. After receiving the information, the background server will perform further processing and analysis to extract key information such as the usage and idle status of the parking space. Finally, the background server pushes the processed image information to the App used by the pile owner through the API interface. The pile owner only needs to open the App to view the status and image information of the parking space in real time without having to go to the site in person, which greatly improves the convenience of use. At the same time, the App also provides a variety of functions, such as making reservations for parking and paying fees, which further enhances the user experience. The application of sentry mode not only improves the efficiency of parking space management, but also brings great convenience to pile owners. Through real-time monitoring and remote operation, pile owners can better understand the usage of parking spaces. Figure 4 shown
[0037] Gun head wake-up switch circuit: By simulating the principle of detecting CC value on the vehicle side, a switch S6 is connected in series between CC detection point ⑥ and the RC resistor. Since S3 is normally closed, as long as the gun head is inserted into the vehicle socket, the circuit resistance detected by CC is the RC resistance. When the added switch S6 is disconnected, the resistance value detected by CC is 0 ohms, which is equivalent to the state when the gun is not plugged in. When the added switch S6 is closed, the resistance value detected by CC is the RC value (220Ω), which is equivalent to the action of inserting the gun head into the vehicle socket. At this time, after the vehicle side detects the resistance value, it will resend the charging message, and the charging pile will restart charging. Figure 4 shown.
[0038] like Figure 5As shown in the figure, a flyback transformer circuit is shown. The input terminal Vin is connected to the mains. The input terminal Vin is divided into an L line and an N line.

[0040] like Figure 7 As shown in the figure, the LDO step-down circuit has the positive end of the 5V input voltage connected to one end of capacitor C25, one end of capacitor C27 and the Vin end of the voltage regulator.
