Intelligent ground locks can realize real-time sensing of whether the parking space is occupied by installing sensing devices such as geomagnetic sensors and pressure sensors in the parking space, and upload information to the management platform through a wireless communication module (such as 4G, NB-IoT).

[0029] The embodiments of the present application provide three technical solutions, specifically including the following embodiments:

[0033] The infrared sensing unit 011 includes an infrared emitter, an infrared receiver, and a signal processing subunit; the infrared emitter is used to emit infrared light of a specific wavelength; the infrared receiver is used to receive the reflected infrared light; the signal processing subunit is used to process the received infrared signal to determine whether there is human activity to sense getting on and off the vehicle. The infrared sensing unit 011 senses the driver getting on and off the vehicle by detecting the infrared radiation of the human body. This unit includes an infrared emitter, an infrared receiver, and a signal processing subunit. The infrared emitter is used to emit infrared light of a specific wavelength, usually 8-14 μm of infrared light, because the infrared radiation of the human body is relatively strong in this wavelength range. The infrared receiver is used to receive the reflected infrared light, which can convert the infrared light signal into an electrical signal. The signal processing subunit is used to process the received infrared signal, when there is human movement, it will cause the reflection of infrared light to change, the signal processing subunit analyzes this change to determine whether there is human activity, thereby sensing the driver getting on and off the vehicle. For example, when the driver is preparing to get off the vehicle, the body movement will cause the infrared light intensity received by the infrared receiver to change, the signal processing subunit compares this change with the preset threshold value, if it exceeds the threshold value, it is judged that the driver gets off the vehicle.

[0052] Specific working process of each module

[0053] Working process of human body sensing module 01

[0054] When the vehicle drives into the parking space, the infrared emitter of the infrared sensing unit 011 continuously emits 8-14 μm infrared light, and the infrared receiver receives the reflected light.

[0055] The signal processing subunit monitors the received infrared signal in real time. When the driver prepares to get off the vehicle, the body movement causes the intensity of the reflected light to change. The signal processing subunit compares the changed signal with a preset threshold value. If the changed signal exceeds the threshold value, it is determined that the driver is about to get off the vehicle, and the information is sent to the core control center.

[0056] At the same time, the millimeter wave transmitter of the millimeter wave radar sensing unit 012 emits a millimeter wave signal, and the millimeter wave receiver receives the reflected signal. The data processing subunit analyzes the reflected signal, determines the movement state of the driver through parameters such as Doppler shift, further confirms whether the driver gets off the vehicle, and sends the result to the core control center.

[0057] The camera of the image recognition sensing unit 013 captures the image of the driver's seat area. The image acquisition card converts the image into a digital signal. The image analysis subunit uses a target detection algorithm based on deep learning to recognize the image. If the human body in the driver's seat is detected to leave, it is determined that the driver has gotten off the vehicle, and the information is sent to the core control center.

[0058] The core control center comprehensively judges the information from the three sensing units to determine the getting on and off state of the driver.

[0059] Workflow of the voice interaction module 02

[0060] The core control center determines the current parking scene according to the information from the vehicle detection unit and the human body sensing module, such as vehicle entering and ground lock rising.

[0061] The text input subunit of the speech synthesis unit 021 receives the scene information from the core control center, and calls the preset corresponding text information, such as "Welcome to the intelligent parking" when the vehicle enters.

[0062] The speech synthesis engine converts the text information into a voice signal. The speech optimization subunit performs noise reduction, adjustment of speech speed and tone, and other optimization processing on the voice signal.

[0063] The optimized voice signal is transmitted to the voice playing unit and amplified by the power amplifier before being played through the loudspeaker.

[0064] When the driver issues a voice command, the voice recognition unit 022 receives the voice signal, performs voice enhancement processing, and converts it into text information using a voice recognition algorithm. The text information is transmitted to the core control center, which responds accordingly and further interacts with the driver through the voice interaction module.

[0065] Workflow of the parking fee management module 03

[0066] When the vehicle enters the parking space, the geomagnetic sensor of the vehicle detection unit 031 detects the change of the geomagnetic field, and the pressure sensor detects the change of the pressure, both of which send signals to the core control center, and the core control center judges that the vehicle enters, at the same time, the license plate recognition sub-unit shoots the license plate image and recognizes the license plate information, and compares with the information in the system.

[0067] The core control center sends a start timing instruction to the timing and charging unit 032, and the real-time clock module of the timing and charging unit 032 records the time when the vehicle enters, and starts timing.

[0068] When the vehicle is ready to leave, after the driver completes the payment, the payment management unit 033 sends the payment success information to the core control center, and the core control center sends a stop timing instruction to the timing and charging unit, the timing and charging unit calculates the parking time, and calculates the parking fee according to the preset rate, and feeds back the fee information to the payment management unit for recording.

[0069] When the vehicle leaves, the geomagnetic sensor and the pressure sensor of the vehicle detection unit 031 detect the corresponding changes, and send signals to the core control center, and the core control center judges that the vehicle leaves, and completes the parking record.

[0070] Workflow of data communication module 04

[0071] During the operation of the system, the data generated by each module, such as vehicle information, parking time, payment information, etc., is transmitted to the data communication module through the internal data bus.

[0072] For large amounts of real-time data, such as vehicle images and detailed parking records, the data communication module 04 uploads them to the external management platform through the 4G communication unit 041, and receives the control instructions issued by the management platform

[0073] Meanwhile, the contents not described in detail in the specification all belong to the existing technology known to those skilled in the art.

[0074] The above embodiments of the application are described in detail, but the content described is only the preferred embodiment of the application, and cannot be considered as limiting the scope of the implementation of the application. Any equivalent changes and improvements made according to the scope of the application should still belong to the patent coverage range of the application.
