Description

Technical Field

[0001] The present invention relates to the technical field related to parking lots, and in particular to a barrier lifting method and a barrier lifting device for unmanned parking lots. Background Art

[0002] Unmanned means that the entrances and exits of the parking lot are released automatically or by the car owner themselves. Without human intervention, the intelligent management system can achieve a convenient vehicle access management mode without stopping and card collection.

[0003] When a vehicle enters the parking lot, the intelligent recognition system at the entrance will automatically identify the license plate number and lift the barrier to let the vehicle pass. At the same time, the mobile phone will push an entry notification to the owner's mobile phone, displaying the vehicle's entry time and other information. First-time users only need to follow the WeChat official account and bind the license plate number to receive the information. Before the vehicle leaves the parking lot, the owner only needs to click on the corresponding entry information pushed by the WeChat official account, enter the payment page, and complete the parking fee payment. For users who have activated the account password-free payment function, if the account balance is sufficient, there is no need to perform any operation. The system will automatically deduct the corresponding parking fee and then let the vehicle pass.

[0004] The above designs are all based on the premise that the power supply and network in the unmanned parking lot are normal. However, in the actual operation process, there are often network disconnections or even power outages. Such situations will cause the cars in the unmanned parking lot to be unable to pay the fees due to network disconnection, resulting in the vehicles being unable to leave; or the entire barrier-lifting game is completed due to power outages, which will also cause the vehicles to be unable to leave. Summary of the invention

[0005] The present invention aims to overcome the above-mentioned deficiencies in the prior art and provides a method for lifting a barrier in an unmanned parking lot and a power-off barrier lifting device capable of ensuring that vehicles leave.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A method for lifting a barrier in an unmanned parking lot, specifically including the following two methods:

[0008] (1) Offline parking barrier lifting: When a vehicle enters a parking lot, the license plate recognition system obtains vehicle information and stores it in the local server. The local server then controls the parking barrier to lift and release the vehicle. When the vehicle leaves the parking lot, the license plate recognition system obtains vehicle information again and stores it in the local server. At the same time, after obtaining payment account information, the local server controls the parking barrier to lift and release the vehicle.

[0009] (2) Power off and lift the barrier: When a vehicle enters the parking lot, the user's mobile terminal scans the QR code to connect to the parking lot cloud server and uploads the vehicle information to the parking lot cloud server. The cloud server then switches the parking barrier to a mechanical transmission mode until the vehicle enters the parking lot and then resets it to an electric transmission mode. When the vehicle leaves the parking lot, the user's mobile terminal scans the QR code again to connect to the parking lot cloud server and uploads the vehicle information to the parking lot cloud server. After obtaining the payment account information, the cloud server then switches the parking barrier to a mechanical transmission mode until the vehicle leaves the parking lot and then resets it to an electric transmission mode.

[0010] The present application is aimed at the management of unmanned parking lots in the case of network outages, and adopts a delayed payment method. The vehicle information and related fee information are first recorded in the local server. After the local server is connected to the parking lot's cloud server, the vehicle charging information in the case of network outages is uploaded to the parking lot's cloud server. The parking lot's cloud server charges the vehicle according to the payment account information reserved by the owner. The vehicle will not be unable to leave the parking lot due to network outages, nor will the charging be impossible due to network outages, thereby ensuring the reliable operation of the parking lot. For the management of unmanned parking lots in the case of power outages, an electric lock is designed at the exit and entrance of the parking lot to lock and unlock the lifting and lowering of the parking rod. When the parking rod is unlocked and can be raised and lowered, the parking rod is opened by mechanical transmission to allow the vehicle to enter and leave the parking lot. As for the parking fee issue of the vehicle, the payment of the vehicle fee is completely realized by connecting the user's mobile terminal to the parking lot's cloud server. This design can ensure the reliable operation of the parking lot and will not cause the entire parking lot to be unusable due to power outages.

[0011] Preferably, in method (1), the specific operation is as follows:

[0012] (11) When a vehicle enters the parking lot, a camera is installed at the entrance of the parking lot, and the camera takes a photo of the vehicle and obtains the vehicle information through the license plate recognition system and stores it in the local server;

[0013] (12) The local server displays the obtained vehicle information on the touch screen at the entrance of the parking lot. After the user confirms that the vehicle information is correct on the touch screen, the local server controls the parking bar to lift the bar and release the vehicle;

[0014] (13) When a vehicle leaves the parking lot, a camera is also installed at the exit of the parking lot. The camera takes a photo of the vehicle and obtains the vehicle information again through the license plate recognition system and stores it in the local server;

[0015] (14) The local server settles the fees using the vehicle information obtained twice and stores the fee settlement information in the local server. At the same time, the local server obtains the payment account information from the touch screen at the exit of the parking lot. After receiving the payment account information, the local server verifies that the account is valid and then controls the parking lever to lift the lever to release the vehicle.

[0016] By confirming and verifying the payment account information, it can be ensured that the parking lot can reliably charge the vehicles in the parking lot, ensuring the normal use of the parking lot.

[0017] Preferably, in step (11), the vehicle information includes a vehicle photo, a license plate number, and an entry time; in step (13), the vehicle information includes a vehicle photo, a license plate number, and an exit time. The design of the vehicle photo allows the owner to intuitively confirm whether it is the vehicle, thereby improving the efficiency of vehicle information confirmation.

[0018] Preferably, in step (12), if the vehicle is an unlicensed vehicle, the local server will automatically generate a number based on the vehicle photo, and display the number on the touch screen, waiting for confirmation; if the vehicle's license plate can only be partially recognized, the local server will display the recognized partial license plate on the touch screen, waiting for the owner to complete the license plate information and touch the screen for confirmation. The above design can ensure that every vehicle can be parked smoothly in the parking lot.

[0019] Preferably, in step (14), the local server will display the fee settlement details on the touch screen and wait for the car owner to input the payment account information. A QR code will be generated on the touch screen to directly obtain the payment account information. The car owner can choose to manually input or scan the QR code on the mobile terminal to generate the payment account information on the touch screen, and then confirm it. After confirming the payment account information, the local server obtains the payment account information confirmed by the car owner, and then verifies the correctness of the payment account information, including the format verification of the payment account and the name verification of the payment account. After both verifications are passed, the car is released. Since the car is disconnected at this time, the local server will upload the fee settlement details and payment account information to the parking lot cloud server for deduction processing after connecting to the parking lot cloud server. Through the above design, the operation can be performed even when the user's mobile terminal is unavailable, which improves the operational reliability of the parking lot.

[0020] Preferably, in method (2), the specific operation is as follows:

[0021] (21) When a vehicle enters a parking lot, the user's mobile terminal scans the QR code at the entrance of the parking lot and connects to the parking lot cloud server. The user's mobile terminal uploads the vehicle information to the parking lot cloud server.

[0022] (22) After receiving the vehicle information, the cloud server generates a dynamic unlocking code and sends the dynamic unlocking code to the electric lock on the parking pole at the entrance. The electric lock controls the lock head to switch the parking pole to the mechanical transmission mode, and the car enters the parking lot by cutting off the power and lifting the pole. After the entire vehicle enters the parking lot, the parking pole falls to give the electric lock a reset message, thereby resetting the parking pole to the electric transmission mode;

[0023] (23) When the vehicle leaves the parking lot, the user's mobile terminal scans the QR code at the parking lot exit and connects to the parking lot cloud server. The user's mobile terminal uploads the vehicle information to the parking lot cloud server.

[0024] (24) The parking lot cloud server settles the fees using the vehicle information obtained twice and sends the fee settlement information to the user's mobile terminal. After the user's mobile terminal completes the payment, the parking lot cloud server will generate a dynamic unlocking code again and send the dynamic unlocking code to the electric lock on the parking pole at the exit. The electric lock controls the lock head to switch the parking pole to a mechanical transmission mode, and the car is allowed to enter the parking lot by cutting off the power and lifting the pole. After the entire vehicle leaves the parking lot, the parking pole falls to give the electric lock a reset message, thereby resetting the parking pole to an electric transmission mode.

[0025] Through the above-mentioned method design, the parking lot cloud server can control the parking rod to switch to a mechanical transmission mode while obtaining vehicle entry and exit information, so that when a vehicle enters, the parking rod is raised and lowered by the vehicle acting on the mechanical transmission mode. At the same time, the information between the raising and lowering of the parking rod can be obtained to charge the vehicle, thereby ensuring the reliable operation of the parking lot.

[0026] Preferably, in step (21), the vehicle information includes the license plate number and the entry time; in step (23), the vehicle information includes the license plate number and the exit time; if the vehicle is an unlicensed vehicle, the user can input the driver's license number of the vehicle owner as the license plate number on the mobile terminal. This design enables every vehicle to enter the parking lot for parking.

[0027] Preferably, in step (22) and step (24), the power-off lever lifting device is provided with active teeth, the parking rod is provided with driven teeth, and the lock is provided with connecting teeth. When the active teeth on the power-off lever lifting device mesh with the driven teeth on the parking rod through the connecting teeth, the vehicle acts on the power-off lever lifting device to cause the power-off lever lifting device to operate, which drives the driven teeth on the parking rod to operate through the connecting teeth, thereby realizing the lifting and lowering of the parking rod. The entire method is a mechanical transmission method. The state of the parking rod is determined by detecting the rotation angle of the connecting teeth on the lock. After the parking rod is lowered, the lock controls the separation between the connecting teeth and the active teeth and the driven teeth. Through the above design, the parking rod raising and lowering processing for each vehicle is realized, preventing multiple vehicles from entering the parking lot together.

[0028] The present invention also provides a power-off lifting rod device, which is installed on the ground at the entrance and exit of a parking lot, and includes a parking rod, a vehicle rod pile, a transmission rod and a pressing pedal. A rotating shaft 1 is provided inside the upper end of the vehicle rod pile, and a rotating shaft 2 is provided inside the upper end of the vehicle rod pile and placed below the rotating shaft 1. One end of the transmission rod is installed inside the lower end of the vehicle rod pile, and a connecting rod is provided at one end of the parking rod, and one end of the connecting rod is connected to the parking rod, and the other end of the connecting rod is installed on the rotating shaft 1 and rotatably connected to the rotating shaft 1. A gear 1 is fixedly installed on the other end of the connecting rod, and a gear 2 is provided on the rotating shaft 2, and the gear 2 is rotatably connected to the rotating shaft 2. A transmission gear 1 is provided on the end of the transmission rod where the vehicle rod pile is located, and the transmission gear 1 is fixedly connected to the transmission rod, and the gear 2 is connected to the transmission gear 1 through a chain 1. An electric control lock is provided in the vehicle rod pile, and a lock head is provided on the electric control lock. One end of the lock head is connected with the electric control lock, and the other end of the lock head is provided with a rotating shaft three, and the rotating shaft three is provided with a gear three, the lock head is fixedly connected to the rotating shaft three, and the rotating shaft three is rotatably connected with the gear three, and the other end of the transmission rod is provided with a transmission gear two, and the transmission gear two is fixedly connected to the transmission rod, and a transmission gear three is fixedly installed on one side of the pressing pedal, and the transmission gear three is provided with a transmission gear four meshing therewith, and the transmission gear four is connected to the transmission gear two through a chain two, the lower end of the vehicle pole pile and the transmission rod are both placed under the ground, and a pedal groove is provided on the ground, and the pressing pedal, the transmission gear three and the transmission gear four are all placed in the pedal groove, and a rebounder is provided in the pedal groove, and a magnet matching the rebounder is provided on the pressing pedal, and an axis groove is provided on the vehicle pole pile, and the rotating shaft three is placed in the axis groove, and a pressing spring is provided between the pressing pedal and the pedal groove.

[0029] Through the design of the above structure, when a vehicle wants to enter the parking lot, the electric control lock has placed the gear three on the transmission shaft three between the gear one and the gear two through the lock head, and the gear one, gear two and gear three are already meshed with each other. When the front wheel of the vehicle is placed on the pressing pedal, the pressing pedal is pressed down, and the action of pressing the pedal drives the transmission gear three and the transmission gear four to move synchronously, and the transmission gear four is transmitted to the transmission gear two through the chain two, and the rotation of the transmission gear two causes the transmission gear one to rotate synchronously through the transmission rod, and the rotation of the rotating gear one drives the gear two to rotate through the chain one, and the gear The transmission of gear 2 makes gear 3 and gear 1 rotate synchronously. The rotation of gear 1 drives the parking rod to rotate through the connecting rod, realizing the lifting operation of the parking rod. At the same time, the magnet on the pressing pedal is attracted by the rebounder in the pedal groove to prevent the parking rod from falling when the front wheel of the vehicle leaves the pressing pedal. After that, the rear wheel of the vehicle is placed on the pressing pedal, the rebounder and the magnet are separated from each other, and after the rear wheel of the vehicle leaves the pressing pedal, the parking rod automatically falls under the action of gravity. After the parking rod has finished falling, the electronic lock separates gear 3 from gear 1 and gear 2, and the parking rod loses its mechanical transmission function.

[0030] Preferably, the electric control lock includes a rotating motor, a rotating connecting piece, a single-chip microcomputer, a communication module, an angle sensor and a charging module. The rotating motor is connected to the lock head through a rotating connecting piece. The rotating motor, the communication module and the angle sensor are all electrically connected to the single-chip microcomputer. The rotating motor and the single-chip microcomputer are both connected to the charging module. The angle sensor and the charging module are both installed on gear three. A pneumatic strut is provided between the vehicle pole pile and the parking pole. One end of the pneumatic strut is rotatably connected to the vehicle pole pile, and the other end of the pneumatic strut is rotatably connected to the parking pole. The transmission gear three is provided with a bevel tooth one, and the transmission gear four is provided with a bevel tooth two matching the bevel tooth one. Through the design between the angle sensor on the electric lock and gear three, the state of the parking rod can be detected in real time to ensure the lifting and lowering of the parking rod; and the design between the charging module on the electric lock and gear three enables the rotation of gear three to be converted into electrical energy through the charging module to power the electric lock, and the charging module on the electric lock can also be powered by installing a battery. The battery is in a charging state when there is power, and can power the electric lock when the power is off; the design of the pneumatic strut can prevent the parking rod from falling too fast and posing a safety hazard; the design of the bevel gear one and the bevel gear two realizes the transmission of the vertical angle, making it more convenient to press the pedal.

[0031] The beneficial effects of the present invention are: vehicles will not be unable to leave the parking lot due to network outage and charges will not be made due to network outage, thereby ensuring the reliable operation of the parking lot and preventing the entire parking lot from being unusable due to power outage.

DETAILED DESCRIPTION

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] A method for lifting a barrier in an unmanned parking lot, specifically including the following two methods:

[0037] (1) Offline parking barrier lifting: When a vehicle enters a parking lot, the license plate recognition system obtains vehicle information and stores it in the local server. The local server controls the parking barrier to lift the barrier and release the vehicle. When the vehicle leaves the parking lot, the license plate recognition system obtains vehicle information again and stores it in the local server. At the same time, after obtaining payment account information, the local server controls the parking barrier to lift the barrier and release the vehicle. The specific operation method is as follows:

[0038] (11) When a vehicle enters the parking lot, a camera is installed at the entrance of the parking lot. The camera takes a photo of the vehicle and obtains the vehicle information through the license plate recognition system and stores it in the local server; the vehicle information includes the vehicle photo, license plate number and entry time.

[0039] (12) The local server displays the obtained vehicle information on the touch screen at the entrance of the parking lot. After the user confirms that the vehicle information is correct on the touch screen, the local server controls the parking lever to lift the lever to release the vehicle. If the vehicle is an unlicensed vehicle, the local server will generate a number based on the vehicle photo and display the number on the touch screen, waiting for confirmation. If the vehicle's license plate can only be partially recognized, the local server will display the recognized part of the license plate on the touch screen, waiting for the owner to complete the license plate information and touch the screen to confirm.

[0040] (13) When a vehicle leaves the parking lot, a camera is also installed at the exit of the parking lot. The camera takes a photo of the vehicle and obtains the vehicle information again through the license plate recognition system and stores it in the local server; the vehicle information includes the vehicle photo, license plate number and exit time.

[0041] (14) The local server settles the fees using the vehicle information obtained twice and stores the fee settlement information in the local server. At the same time, the local server obtains the payment account information from the touch screen at the exit of the parking lot. After receiving the payment account information, the local server verifies that the account is valid and then controls the parking bar to lift the bar to release the vehicle. The local server will display the fee settlement details on the touch screen and wait for the car owner to enter the payment account information. A QR code will be generated on the touch screen to directly obtain the payment account information. The car owner can choose to enter the information manually or scan the QR code on the mobile terminal to generate the payment account information on the touch screen and then confirm it. After confirming the payment account information, the local server obtains the payment account information confirmed by the car owner and then verifies the correctness of the payment account information, including the format verification of the payment account and the name verification of the payment account. The vehicle will be released after both verifications are passed. Since the network is disconnected at this time, the local server will upload the fee settlement details and payment account information to the parking cloud server for deduction processing after connecting to the parking cloud server.

[0042] (2) Power off and lift the barrier: When a vehicle enters a parking lot, the user's mobile terminal scans the QR code to connect to the parking lot cloud server and uploads the vehicle information to the parking lot cloud server. The cloud server then switches the parking barrier to a mechanical transmission mode until the vehicle enters the parking lot and resets it to an electric transmission mode. When the vehicle leaves the parking lot, the user's mobile terminal scans the QR code again to connect to the parking lot cloud server and uploads the vehicle information to the parking lot cloud server. After obtaining the payment account information, the cloud server then switches the parking barrier to a mechanical transmission mode until the vehicle leaves the parking lot and resets it to an electric transmission mode. The specific operation method is as follows:

[0043] (21) When a vehicle enters the parking lot, the user's mobile terminal scans the QR code at the entrance of the parking lot and connects to the parking lot cloud server. The user's mobile terminal uploads the vehicle information to the parking lot cloud server; the vehicle information includes the license plate number and the time of entry. If the vehicle is unlicensed, the user's mobile terminal can enter the owner's driver's license number as the license plate number.

[0044] (22) After receiving the vehicle information, the cloud server generates a dynamic unlocking code and sends the dynamic unlocking code to the electric lock on the parking pole at the entrance. The electric lock controls the lock head to switch the parking pole to the mechanical transmission mode, and the car enters the parking lot by cutting off the power and lifting the pole. After the entire vehicle enters the parking lot, the parking pole falls to give the electric lock a reset message, thereby resetting the parking pole to the electric transmission mode;

[0045] (23) When a vehicle leaves the parking lot, the user's mobile terminal scans the QR code at the parking lot exit and connects to the parking lot cloud server. The user's mobile terminal uploads the vehicle information to the parking lot cloud server; the vehicle information includes the license plate number and exit time.

[0046] (24) The parking lot cloud server settles the fees using the vehicle information obtained twice and sends the fee settlement information to the user's mobile terminal. After the user's mobile terminal completes the payment, the parking lot cloud server will generate a dynamic unlocking code again and send the dynamic unlocking code to the electric lock on the parking pole at the exit. The electric lock controls the lock head to switch the parking pole to a mechanical transmission mode, and the car is allowed to enter the parking lot by cutting off the power and lifting the pole. After the entire vehicle leaves the parking lot, the parking pole falls to give the electric lock a reset message, thereby resetting the parking pole to an electric transmission mode.

[0047] The power-off rod lifting device is provided with a driving tooth, the parking rod is provided with a driven tooth, and the lock head is provided with a connecting tooth. When the driving tooth on the power-off rod lifting device is meshed with the driven tooth on the parking rod through the connecting tooth, the vehicle acts on the power-off rod lifting device to activate the power-off rod lifting device, which drives the driven tooth on the parking rod to move through the connecting tooth, thereby realizing the lifting and lowering of the parking rod. The entire method is a mechanical transmission method. The state of the parking rod is determined by detecting the rotation angle of the connecting tooth on the lock head. After the parking rod is lowered, the lock head controls the separation between the connecting tooth and the driving tooth and the driven tooth.

[0048] The present application aims at the management of unmanned parking lots in the case of network outages, and adopts a delayed payment method. The vehicle information and related fee information are first recorded in the local server. After the local server is connected to the parking lot's cloud server, the vehicle charging information in the case of network outages is uploaded to the parking lot's cloud server, and the parking lot's cloud server charges the vehicle according to the payment account information reserved by the car owner. For the management of unmanned parking lots in the case of power outages, an electric lock is designed at the exit and entrance of the parking lot to lock and unlock the lifting and lowering of the parking rod. When the parking rod is unlocked and can be raised and lowered, the parking rod is opened by mechanical transmission to allow vehicles to enter and leave the parking lot.

The rotating motor is connected to the lock head 14 through a rotating connecting piece. The rotating motor, the communication module and the angle sensor are all electrically connected to the single-chip microcomputer. The rotating motor and the single-chip microcomputer are both connected to the charging module. The angle sensor and the charging module are both installed on gear three 12. A pneumatic strut 5 is provided between the vehicle pole pile 11 and the parking pole 4. One end of the pneumatic strut 5 is rotatably connected to the vehicle pole pile 11, and the other end of the pneumatic strut 5 is rotatably connected to the parking pole 4. A bevel tooth 1 21 is provided on the transmission gear three 20, and a bevel tooth 2 23 matching the bevel tooth 1 21 is provided on the transmission gear four 22.

[0051] When the vehicle is about to enter the parking lot, the electric control lock 15 receives information through the communication module to control the operation of the rotating motor through the single chip microcomputer. The action of the rotating motor controls the extension of the lock head 14 through the rotating connecting piece. The gear three 12 on the rotating shaft three 13 is placed between the gear one 1 and the gear two 7 through the lock head 14 so that the gear one 1, the gear two 7 and the gear three 12 are meshed with each other. When the front wheel of the vehicle is placed on the pressing pedal 19, the pressing pedal 19 is pressed downward, and the pressing spring therein is compressed. The action of the pressing pedal 19 drives the transmission gear three 20 and the transmission gear four 22 to move synchronously. The transmission gear four 22 is transmitted to the transmission gear two 25 through the chain two 24, and the rotation of the transmission gear two 25 passes through the transmission rod 9 to make the transmission gear one 10 rotate synchronously, and the rotation of the rotating gear one 1 drives the gear two 7 to rotate through the chain one 8, and the transmission of the gear two 7 makes the gear three 12 and the gear one 1 rotate synchronously, and the rotation of the gear one 1 drives the parking lock through the connecting rod 3 When the rear wheel of the vehicle leaves the pressing pedal 19, the parking rod 4 automatically falls down due to the action of its own gravity and the action of the pressing spring on the pressing pedal 19. A pneumatic strut 5 is designed between the parking rod 4 and the vehicle rod pile 11 to make the parking rod 4 fall slowly. After the parking rod 4 has fallen, the angle sensor on the electric control lock 15 detects the state of the parking rod 4 and sends a signal to the single chip microcomputer, so that the single chip microcomputer controls the rotating motor to drive the lock head 14 to retract through the rotating connecting piece, so that the gear three 12 on the rotating shaft three 13 is separated from the gear one 1 and the gear two 7, and the parking rod 4 loses its mechanical transmission effect.
