In addition, the rotation pivot of the supporting slide rail component 13 in the two U-shaped guide rails also adopts a nonmetallic structural component to complete supporting and forced rotation, so that only one effective main current loop from the charging pile 1 to the top cover 10 is ensured, the effective transmission of electric energy can be realized, and the energy requirement of the intelligent parking space ground lock system control is met.
Referring to fig. 3, an electronic circuit board is disposed in the top cover 10, the electronic circuit board includes a central processing unit 20, a constant current source module 21, a power management unit 22, a driving circuit 23, and a vehicle identification monitoring module 24, a regulated power supply circuit 25 is connected between the constant current source module 21 and the power management unit 22, the central processing unit 20 is electrically connected with the power management unit 22 and the driving circuit 23 respectively, the central processing unit 20 receives a vehicle identification signal sent by the vehicle identification monitoring module 24, and the driving circuit 23 outputs a driving signal to the supporting slide rail assembly 13.
The driving circuit 23 may be used to drive the movement of the position of the slide rail 132 of the intelligent parking space ground lock, so that when receiving an action command, the top cover 10 of the intelligent parking space ground lock can raise or lower according to the command to complete the blocking control of the illegal vehicle entering the parking space.
Referring to fig. 4, the constant current source module 21 includes a resistor R1, a resistor R2, a resistor R3, a resistor R4, a resistor R5, a resistor R6, a resistor R7, a resistor R8, a capacitor C1, and a capacitor C2, where the resistor R1, the resistor R2, the resistor R6, and the resistor R7 are all wire resistors, the resistor R3 and the resistor R5 are all rail arm resistors, the resistor R4 is a ground resistor, and the capacitor C1 and the capacitor C2 are all stray capacitors. The constant current source module 21 mainly receives the low-voltage constant current source transmitted by the charging pile 1 as the main power supply supplement and supply of the system, the low-voltage constant current source can be 6.3V voltage, and the low-voltage constant current source adopting the current not exceeding 320mA sequentially enters the guide rail 15 of the base assembly and the supporting slide rail assembly 13 through the conductive rail, so as to enter the top cover 10.
Because the front end provides an effective 6.3V low-voltage direct current constant current source, various resistors in the circuit can not change the power supply current, and the voltage is gradually reduced, the voltage loss during long-distance low-voltage transmission is avoided, the voltage injury caused by arrangement of the intelligent parking space ground lock is avoided, and particularly, when the circuit is completely soaked by water, the interruption of the current circuit can not be caused, so that the intelligent parking space ground lock in the embodiment can timely complete the instruction sent by the charging pile 1 in any environmental state.
Referring to fig. 5, the regulated power supply circuit 25 includes a current input end 6, a voltage output end 8, a diode VD, a capacitor Ca, an operational amplifier IC, a transistor VT, a thyristor Ver and a varistor Rv, particularly, in order to adapt to the installation of the outdoor environment of the charging pile 1 and the normal on/off of the intelligent parking space ground lock, the regulated power supply circuit 25 outputs a stable voltage of 24V, and in order to match the normal operation of other electronic circuits and adapt to the fully-sealed temperature rise condition, the transistor VT in the circuit is a combined darlington tube structure, the diode VD is a fast recovery diode, and the capacitor Ca adopts a tantalum capacitor with a large capacity. After receiving the current sent by the current loop formed by the supporting slide rail assembly 13, the voltage-stabilizing power supply circuit 25 performs basic conversion from a current source to a voltage source, so that the external power supply loop provides working power supply guarantee for the intelligent parking space ground lock under the combined action of the external power supply loop, the system internal power supply management unit 22 and the backup energy storage battery 5. Specifically, when the constant current source current reaches the present stage circuit, the current source in the front stage circuit is converted into 24V voltage source output which is beneficial to the operation of the rear stage electronic circuit under the operation of the diode VD, the capacitor Ca, the operational amplifier IC, the transistor VT and the auxiliary elements thereof. The thyristors Ver and the piezoresistors Rv in the circuit are key elements set for stabilizing a voltage source.

In addition, to meet the short-time high-current requirement of supporting the slide rail assembly 13, the electronic circuit board further includes an energy storage battery 5, and the energy storage battery 5 is electrically connected with the power management unit 22. Since the energy storage battery 5 normally does not require external intervention for energy replenishment, the sealing process of the electronic paste is also performed as in the overall control system.
Preferably, the electronic circuit board further includes a wireless communication unit 26, and the wireless communication unit 26 is electrically connected to the central processor 20. The wireless communication unit 26 may be a wireless communication module such as a WiFi communication module or a bluetooth communication module, for example, when the wireless communication unit 26 is a bluetooth communication module, the bluetooth communication module may match with effective information processing between the charging pile 1 and the parking space ground lock to complete information exchange, and after receiving information transmitted by the bluetooth communication module, the central processor 20 may effectively analyze the information, and perform effective parking space lock opening and closing processing according to a corresponding data processing flow and in cooperation with effective vehicle identification information.
Preferably, the electronic circuit board further includes an alarm unit 27, and the central processor 20 outputs an alarm signal to the alarm unit 27. In addition, the alarm unit 27 is a set of clutch mechanisms arranged inside the top cover 10, so that the intelligent parking space ground lock can be ensured to be suitable for the management application of complete power failure, and when an authorized person opens the protective cover on the top cover 10 through an effective mechanical means, the intelligent parking space ground lock can be opened and closed manually by adopting a special mechanical accessory. Of course, this manual operation will be regarded as "location anomaly" to give an alarm when the power supply is normal.
In the present embodiment, the vehicle identification detection module 24 includes a wireless geomagnetic detector 28 and a radio frequency identification unit 29, and the central processor 20 is electrically connected to the wireless geomagnetic detector 28 and the radio frequency identification unit 29, respectively. The vehicle identification detection can judge and give out effective information by combining geomagnetic parking space occupation and parking vehicle RFID information. For example, the wireless geomagnetic detector 28 collects whether a vehicle is parked in the current parking space and whether the vehicle has been timely moved away, and the rfid unit 29 is responsible for processing the determination of the information of the parked vehicle and sending a conditional instruction to the cpu 20 whether to unlock the parking space lock.

The ground lock state monitoring unit 30 is a position switch arranged in the top cover 10, can coordinate the control instruction of the charging pile 1, and can avoid the illegal actions that the next illegal parking needs to forcedly intrude into a parking space by taking a gap or violently destroy the parking space when the current vehicle is legal to leave.
Of course, in order to ensure that the intelligent parking space ground lock is suitable for the outdoor installation condition of the charging pile 1, the functional units on the electronic circuit board are independently processed except for the body of the energy storage battery 5, all the functional units are sealed in the inner space of the top cover 10 by the solidified electronic glue, and the intelligent parking space ground lock is in a full-waterproof working state, and the energy storage battery 5 also takes corresponding outdoor flood control level protection measures.
In this embodiment, when the intelligent parking space lock is operated, the control process completes the control of the intelligent parking space lock according to the basic flow which firstly meets the requirement of the charging user, and the opening and closing of the intelligent parking space lock is mainly implemented after the necessary information collection and comparison are completed through the wireless communication module 26 and the charging pile 1. Whether the charging pile 1 gives a control instruction or not, after the first installation and debugging are finished, the intelligent parking space ground lock automatically adjusts the autonomous state (with external current access condition) according to the parking space closing state. That is, when the current parking space is in the empty state, the intelligent parking space ground lock feeds back information of the empty parking space to the charging pile 1 through wireless communication, and at this time, the intelligent parking space ground lock is in a parking space empty protection state (locking/locking).
Therefore, the supporting slide rail component 13 of the intelligent parking place ground lock provided by the invention adopts a conventional X-shaped matrix physical structure, the top cover 10 is internally provided with the central processing unit 20 for autonomous operation, the electric power is actively driven and controlled, and the effective unmanned parking place is implemented by combining the vehicle charging information provided by the charging pile 1, the vehicle identification information installed on the ground of the parking place and the entering vehicle identification information, so that the automatic management control for temporarily and effectively controlling the time parking is provided for the charging vehicle as a main service and the non-charging vehicle.
In addition, the intelligent parking spot lock adopts a wired power supply supplement of the safe low-voltage milliamp-level double-track constant current source module 21, and a terminal energy storage high-power short-time discharging power supply processing mode to complete the driving of the intelligent parking spot ground lock mechanical structure and the processing support of internal data operation, information storage, vehicle identification correction and other works, so that the intelligent parking spot lock is suitable for various outdoor rain and snow immersion and flooding and other severe application environments, a charging user does not need to get off the car or manually operate, match and verify, and interfere to open and close the parking spot lock before and after parking, and does not need to pay special attention to the power utilization of the parking spot ground lock or charge and store energy separately during maintenance, so that the user experience effect can be improved.
The embodiment of the method for verifying the use of the intelligent parking spot ground lock comprises the following steps:
in this embodiment, the method for verifying the use of the intelligent parking space ground lock includes: when the intelligent parking space ground lock receives a lock control instruction sent by the charging pile 1, the intelligent parking space ground lock judges whether a vehicle requesting to enter is a charging requirement or not, and if the vehicle requesting to enter is determined to be the charging requirement and the current parking space is in a vacant state, the intelligent parking space ground lock reads reservation information of the vehicle and stores the reservation information into a historical information base; when the vehicle reaches the current parking space, the intelligent parking space ground lock performs radio frequency information verification on the vehicle, and if the vehicle passes the information verification, the vehicle is allowed to perform charging operation.
If the vehicle is determined to be in a charging completion state, the intelligent parking space ground lock monitors whether the vehicle normally drives away from the current parking space in real time, and if the vehicle is determined to normally drive away and the intelligent parking space ground lock receives a closing instruction sent by the charging pile 1, the intelligent parking space ground lock executes a locking action.
If the vehicle requiring parking is determined to be a non-charging parking requirement, the intelligent parking place ground lock confirms that the current parking place is in an empty state according to the historical information base, if the current parking place is determined to be in the empty state and has idle time, the vehicle requiring non-charging parking is allowed to carry out parking operation, whether the vehicle requiring non-charging parking meets a preset parking permission condition is judged, if the judgment result is negative, the intelligent parking place ground lock sends a preset voice prompt signal.
If it is determined that the intelligent parking place ground lock is in an abnormal state, the intelligent parking place ground lock detects abnormal signals and outputs audible and visual alarm signals, and the intelligent parking place ground lock sends the abnormal signals to the charging pile 1. The intelligent parking space ground lock automatically detects the abnormal state such as violent collision, outputs an audible and visual alarm prompt through the alarm unit 27, and feeds the abnormal signal back to the charging pile system platform to prompt that the current intelligent parking space ground lock is in an abnormal state.
In a specific application, when the intelligent parking place lock of the embodiment receives a lock control instruction sent by the charging pile 1, the central processing unit 20 in the top cover 10 first judges whether the instruction is a charging requirement of a vehicle requesting to enter, if so, the current parking place occupation condition is fed back to the charging pile 1, and the charging pile system platform completes man-machine conversation with a user. At this time, the intelligent parking place ground lock executes the next useful action according to whether the current parking place is empty or not, and otherwise, the intelligent parking place ground lock returns to the waiting state.
If the vehicle which is requested to park is a non-charging parking request, when the current system history retrieval and comparison is carried out through the intelligent parking space ground lock to confirm whether the current parking space is in an empty state and in an idle time, a request for reading information of the parked vehicle is provided for charging pile 1 information, if the current parking space is determined to be in the empty state and after the idle time is provided, the vehicle which is not required to park is allowed to park, whether the vehicle which is not required to park is in accordance with a preset parking permission condition is judged, if the judgment result is no, the intelligent parking space lock sends a preset voice prompt signal to remind a user to drive away from the parking space. Of course, if it is determined that the current parking space is not in the idle state and there is no idle time, the current instruction is directly ignored and the wait is returned. The parking permission condition comprises judging whether the current parking space is always in a vacant state and whether the current parking space has vacant time, if the intelligent parking space ground lock receives that the lock control instruction sent by the charging pile 1 is when other vehicles requiring parking are in charging demands, the condition that the vehicles requiring non-charging parking do not meet the preset parking permission condition can be judged, and then the intelligent parking space ground lock sends out a preset voice prompt signal to remind a user to drive away from the parking space.
When the information of the vehicle which is sent by the charging pile 1 and requests to park is the charging requirement and the current parking space is in the empty state, the intelligent parking space ground lock sends a request for reading the information of the vehicle. After the intelligent parking place ground lock is authorized, the intelligent parking place ground lock stores the read and upcoming vehicle information in a local storage space, namely a history information base, corresponding history data is formed, the intelligent parking place ground lock verifies RFID information of the vehicle through the radio frequency identification unit 29 after waiting for the vehicle to reach the current parking place, the intelligent parking place ground lock is checked and compared with a charging pile system platform, and only after the vehicle information of the current parking place is verified, the central processor 20 side in the top cover 10 can output an effective parking place ground lock control instruction to give the parking place. Under the normal condition, the parked vehicle will perform effective charging operation, and during the charging operation, the intelligent parking space ground lock body does not receive and process related information, but waits for the charging pile 1 to give a next vehicle lock control instruction to the interface unit of the intelligent parking space ground lock, and determines whether the charging is finished or not through corresponding instruction analysis. If the charging end signal of the current vehicle arrives at the intelligent parking space ground lock, the wireless geomagnetic detector 28 starts to enter a standby state, and whether the current vehicle normally drives away from the parking space is given in real time.
Due to the feedback time of the charging pile charging system and the personal habit problem of the user, the embodiment provides a certain preset time of the system for driving the vehicle away from the parking space, for example, 300 seconds, 400 seconds or more than 500 seconds, and after the vehicle is normally driven away, the intelligent parking space ground lock outputs a corresponding parking space ground lock closing instruction, for example, 100 milliseconds, within a certain time after receiving the closing information output by the charging pile 1. The supporting slide rail assembly 13 is started to jack up the top cover 10, and the control of the parking space is implemented. In the process, if the current vehicle residence time exceeds the preset system time, particularly the residence time is longer than 10 minutes, the intelligent parking space ground lock feeds back the current parking space abnormal occupation information of the charging pile 1, so that the charging pile system platform can give out corresponding control measures until the current vehicle effectively drives away.
In addition, if the intelligent parking space ground lock is in the closing process or after the closing instruction is completed, the ground lock state monitoring unit 30 finds that the current parking space is in an abnormal state, and gives corresponding information, the intelligent parking space ground lock gives a prompt through the alarm unit 27, and feeds back the abnormal information of the current parking space to the charging pile system platform. Specifically, after a previous car normally leaves, when abnormal occupation of other vehicles to the parking space occurs before the intelligent parking space ground lock does not finish parking space closing, the intelligent parking space ground lock judges whether the car normally finishes in place or not, and if not, the situation of occupying the parking space can be considered; judging whether the current top cover 10 of the intelligent parking space ground lock belongs to the vertical direction or not, if not, determining that the action of violently destroying the parking space ground lock is achieved, further giving state abnormality alarm information and feeding back the state abnormality alarm information to a charging pile system platform, and further completing comprehensive control over the current parking space condition. Therefore, the ground lock state monitoring unit 30 can independently complete the complete detection of the ground lock state monitoring unit and give out on-site acousto-optic warning and feed back to the charging pile system platform until the built-in power supply is protected, so that the timeliness of violent damage and bad application of releasing the ground lock, quick investigation and invalid occupation release are ensured.
Obviously, when the user uses the intelligent parking place ground lock, the user does not need to directly carry out corresponding man-machine interaction with the parking place ground lock, and the user does not need to carry out corresponding man-machine dialogue operation or even get-off confirmation operation on the parking place ground lock before using the parking place like other similar parking place ground locks, so that the control flow can be directly simplified, the parking place user can also concentrate on implementing the operation of the vehicle, and the safe running is ensured.
Therefore, the intelligent parking space ground lock use verification method provided by the invention combines the vehicle charging information provided by the charging pile 1, the vehicle identification information installed on the ground of the parking space and the in-parking vehicle identification information to implement effective unmanned parking space management control, which mainly serves the charging vehicle and provides temporary effective management and control time parking for the non-charging vehicle, and the maximum management of the utilization benefit of the charging pile parking space is realized through the technologies of vehicle identification technology, charging pile use state monitoring and the like.
It should be noted that the foregoing is only a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made to the present invention by using the concept fall within the scope of the present invention.
