Description

Technical Field

[0001] The present invention belongs to the technical field of charging equipment, and in particular relates to an intelligent identification system for household charging piles. Background Art

[0002] Home charging piles mainly provide high-quality and safe charging services for electric vehicles. They mainly monitor the data during the charging process at any time while ensuring that the car is charged, adjust the charging process according to the vehicle charging situation, and monitor the safety of electricity use during the charging process at any time. Existing charging piles cannot accurately identify the identity of the owner and the vehicle number. When a non-parking space owner parks the car in front of the charging pile, it will affect the charging of the parking space owner. Existing charging methods usually charge randomly, which may cause the grid load to be too high in certain periods of time, affecting the stability of the grid. It is also not conducive to the rational use of preferential electricity prices such as valley electricity, and increases electricity costs. Summary of the invention

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides a household charging pile intelligent identification system, including: an identity authentication module, a data display and record statistical analysis module, a charging plan module, a safety protection module and a voice prompt module.

[0004] The identity authentication module uses facial information and license plate number for dual verification; The data display and record statistical analysis module includes a display screen that displays the charging progress and full-charge time, and is used to fully record the charging time, power, and cost, which is convenient for query and subsequent statistical analysis; The charging plan module includes three charging modes: immediate charging mode; scheduled charging mode, in which the mobile phone APP establishes a connection with the charging pile via Bluetooth, and controls the charging pile to start charging, end charging time or set a scheduled charging time through the APP; optimal charging mode, which pushes the best charging plan based on the peak electricity price period and the remaining power of the vehicle.

[0005] The safety protection module includes overload protection and rain protection, which will automatically cut off charging when the current or temperature exceeds the safe range. It is equipped with a rain sensor, which can perform power-off protection when it rains, and automatically start charging again when the rain stops.

[0006] The voice prompt module is used to monitor various abnormal situations in real time and promptly remind the owner through sound and light alarms or APP. When the current or temperature is overloaded or it rains, the owner is reminded through the mobile phone APP voice prompt; when other vehicles are parked in the owner's parking space, the charging pile reminds the owner of the vehicle to leave or leave contact information, so that the owner of the parking space can contact him when he needs to charge and leave the vehicle.

[0007] Furthermore, the identity authentication includes a camera device for acquiring facial information and a camera device for acquiring license plate numbers, and transmitting the facial information and license plate numbers to a recognition module through a wireless communication module. The recognition module includes a storage device pre-stored with facial information and license plate numbers. The recognition module recognizes that the collected facial information is consistent with the pre-stored facial information, and the license plate number is consistent with the pre-stored license plate number.

[0008] Furthermore, the data display and record statistical analysis module includes a progress display indicator light electrically connected to the controller output terminal to display the charging progress and full time. The data display and record statistical analysis module is connected to the remote cloud management platform of the charging pile based on the Internet of Things, and the charging pile is loaded with an intelligent charging management system that can communicate with the mobile phone APP.

[0009] Furthermore, the charging plan module includes a client device, and in the reserved charging mode, the client device submits a reserved charging request to the server through the network.

[0010] The beneficial effects of the present invention are: The present invention provides a household charging pile intelligent identification system, including: an identity authentication module, a data display and record statistical analysis module, a charging plan module, an overload protection module and a voice prompt module, which adopts double verification of face recognition and license plate number; can display charging progress, full time, and completely record charging time, power, and cost, which is convenient for query and subsequent statistical analysis; control the charging pile to start charging, charging end time or set a scheduled charging time through APP; according to the peak and closing time of electricity price and the remaining power of the vehicle, push the best charging plan, thereby improving the charging efficiency and user convenience of the charging pile; is used for real-time monitoring of various abnormal situations, timely reminding users through APP, and setting rain sensors to remind users in time when it rains and perform power-off protection; automatically cuts off charging when the current exceeds the safe range, which is conducive to the long-term stable operation of the charging pile.

[0015] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0017] Embodiment 1, as Figure 1-Figure 2 As shown, this embodiment provides a household charging pile intelligent identification system, including: an identity authentication module, a data display and record statistical analysis module, a charging plan module, an overload protection module and a voice prompt module.

[0018] The identity authentication module uses facial information and license plate number for dual verification; Identity authentication includes a camera device that obtains facial information and a camera device that obtains license plate number, and transmits the facial information and license plate number to a recognition module through a wireless communication module. The recognition module includes a storage device that pre-stores facial information and license plate number. The recognition module recognizes that the collected facial information is consistent with the pre-stored facial information, and the license plate number is consistent with the pre-stored license plate number.

[0019] The data display and record statistical analysis module includes a display screen that displays the charging progress and full-charge time, and is used to fully record the charging time, power, and cost, which is convenient for query and subsequent statistical analysis; As an implementation method, the data display and record statistical analysis module includes a progress display indicator light electrically connected to the controller output end, the controller input end is electrically connected to the current detection chip, the current detection chip is electrically connected to the secondary coil of the current transformer, and the current detection chip and the controller are powered by a voltage-stabilized power supply circuit electrically connected to the secondary coil of the current transformer. The charging progress is displayed through the current transformer and the mutual inductance current is detected, and the current charging status is displayed through the indicator light. The data display and record statistical analysis module builds a remote cloud management platform connected to the charging pile based on the Internet of Things, and loads an intelligent charging management system in the charging pile that can communicate with the mobile phone APP; the intelligent charging management system is set with charging time recording, power recording, and cost recording functions, which can realize unified management and facilitate statistical data and maintenance.

[0020] The charging plan module includes three charging modes: immediate charging mode, scheduled charging mode and optimal charging mode.

[0021] As an implementation method, in the scheduled charging mode, the mobile phone APP establishes a connection with the charging pile via Bluetooth. The APP controls the charging pile to start charging, the charging end time, or set the scheduled charging time. In the optimal charging mode, a reasonable charging plan is automatically given by comprehensively considering the current remaining power of the vehicle and the peak and valley periods of the local electricity price. If the remaining power can support the vehicle to travel until the beginning of the low electricity price period, it can be pushed to start charging during the valley period; if the remaining power is not enough to support the valley period, but the vehicle will not be unable to travel due to power exhaustion after the end of the flat electricity price and before the beginning of the valley electricity price, it can be pushed to start charging in the late flat period, and continue to charge until full during the valley period; if the remaining power is very low and may not be able to support the valley period, it will be pushed to charge immediately without considering the electricity price period. The charging plan can be adjusted later according to the charging situation and the time when the valley period arrives, and it will continue to be fully charged during the valley period.

[0022] The safety protection module includes overload protection and rain protection, which will automatically cut off charging when the current or temperature exceeds the safe range. It is equipped with a rain sensor, which can perform power-off protection when it rains, and automatically start charging again when the rain stops.

[0023] As an implementation method, fault detection software is embedded in the intelligent charging management system to monitor the current, voltage and other parameters in the circuit in real time. By comparing the parameter range under normal working conditions, when abnormal current changes are detected, there may be signs of leakage, and the charging circuit is automatically cut off. Temperature sensors are installed in key heating parts inside the charging pile, such as power modules and cable connections, to monitor the temperature of these parts in real time. The temperature sensor transmits the collected temperature signal to the control chip or microcontroller of the charging pile, and compares the real-time temperature with the preset over-temperature threshold. When the control chip determines that the temperature exceeds the over-temperature threshold, the over-temperature protection mechanism is immediately triggered, and the charging circuit is automatically cut off and the charging process is stopped to prevent the temperature from further rising, avoiding safety accidents or damage to the equipment. A rain sensor is installed at a suitable position on the top of the charging pile, and the signal output end of the rain sensor is connected to a relay. When the rain sensor detects rain, it outputs a signal to trigger the relay to operate. When the relay operates, the contacts are disconnected, thereby cutting off the charging circuit. When the rain stops, the rain sensor signal is restored, the relay contacts are closed, and the charging circuit resumes normal charging. The rain sensor can adopt a shell having a cover plate formed of a transparent material; a printed circuit board arranged in the shell and having a light emitter, a light receiver, and a temperature sensing element arranged thereon; a transparent compound arranged in the shell and covering the light emitter, the light receiver, and the temperature sensing element, the transparent compound filling the space between the printed circuit board and the cover plate, wherein the transparent compound has a refractive index substantially equal to the refractive index of the cover plate, and wherein the transparent compound provides a heat conductive medium between the cover plate and the temperature sensing element.

[0024] The voice prompt module can monitor various abnormal situations in real time, such as leakage short circuit, overheating, and rain, and can remind the owner in time through sound and light alarm or mobile phone APP. When other vehicles are parked in the owner's parking space, the charging pile will remind the owner of the vehicle to leave or leave contact information, so that the owner can contact him and leave the vehicle when he needs to charge.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
