A control device and method for automatic parking of shared bicycles

Abstract

The present invention provides a control device and method for automatic parking of shared bicycles. While striving for automation, low power consumption, and improved land use efficiency, the human-computer interaction of this solution is fully considered. Without changing the existing structure of shared bicycles themselves, a reasonable and convenient parking device and parking scheme are designed. The device design is divided into three major parts: the waiting area, the waiting-to-go area, and the no-bicycle area. By determining whether the waiting-to-go area is full of bicycles or in a no-bicycle state, the parking rack is driven by a synchronous belt to move towards the waiting area or the no-bicycle area respectively. The parking lot device adopts a low-power design scheme, and the daily power demand of the device can be met by a solar panel during normal use.

Description

Technical Field

[0001] The present invention relates to the field of automated shared bicycle parking lot devices, and particularly to a control device and method for automatic parking of shared bicycles. Background Art

[0002] In 2007, the public bicycle mode that emerged abroad was gradually introduced into China, but its form was mainly the government-led docked public bicycles. In 2014, with the booming development of Internet technology, Internet companies represented by ofo gradually launched Internet-style shared bicycles, replacing docked shared bicycles with more convenient dockless shared bicycles. Bicycles can be "parked and retrieved at will" by scanning the code. During the period from 2014 to 2017, with the introduction of relevant policies such as "energy conservation, emission reduction, and green travel" by the state, Internet-style shared bicycles have entered a period of rapid development. While their development scale is growing larger, there are problems such as random parking, uneven resource allocation, and vehicle damage. In response to the problems of random parking, uneven resource allocation, and vehicle damage of shared bicycles, people from all walks of life have put forward various solutions. For example, Lu Zheng designed a suspended three-dimensional parking device for bicycles, but the number of parked bicycles is small and land resources cannot be fully utilized; Lao Zhuoyuan developed a simple automated three-dimensional bicycle storage system through three-dimensional modeling and model making based on problems such as low safety of bicycle storage and waste of parking space; Guo Fanghui designed a rotary intelligent three-dimensional bicycle garage in combination with the concept of "Internet of Things +"; Zhang Yubin developed a roadway stacking type three-dimensional garage management system for the problem of low automation of the control system of existing three-dimensional garages; Wang Shiwei designed a vertical fully automated bicycle parking system with a suspended parking / suspended traction mechanical structure for the bicycle parking system.

[0003] However, these above-mentioned design solutions have problems such as a small number of parked shared bicycles, insufficient utilization of land resources, and failure to fully consider the convenience of using shared bicycles. Due to the inapplicability of the above-mentioned design solutions, there is still no shared bicycle parking lot solution that can facilitate people's travel, resulting in the introduction of relevant restrictive policies such as designating parking areas and riding areas for shared bicycles in some areas.

[0004] Meanwhile, the shared electric bicycles launched since 2017 also face the above problems. In addition, due to the high temperature impact brought by global warming, shared electric bicycles have a higher risk coefficient compared to shared bicycles because of the batteries and related electronic control equipment they carry, and more safety maintenance measures are needed. Summary of the Invention

[0005] Based on the above background analysis, the present invention, combined with market research, proposes a control device and method for automatic parking of shared bicycles to specifically address prominent problems existing in the development of shared bicycles, such as random parking, inconvenient parking, and serious vehicle damage. It provides an effective special safety protection place for shared bicycles, better maintains the social environment, enhances people's vehicle usage experience, and sustains the development vitality of shared bicycles while giving people a more convenient and free vehicle usage experience.

[0006] The control device and method for automatic parking of shared bicycles proposed by the present invention is somewhat similar to the parked bicycle with a fixed stand solution to a certain extent. However, to reduce the inconvenience brought to people by canceling the dockless parking solution, the present invention makes convenient improvements in the access of shared bicycles and uses current mature sensor technology and simple mechanical movements to achieve the design goals of the product. Based on ergonomics, while realizing the convenient access and parking of vehicles by people, it maximizes the use of the land resources of the parking lot.

[0007] To achieve the above technical features, the object of the present invention is realized as follows: A control device for automatic parking of shared bicycles includes a waiting area, a waiting-to-go area, a no-vehicle area, a guardrail, and a device housing; the waiting-to-go area includes a first motor, a synchronous belt, a driving support frame, a plurality of parking racks, and a first optoelectronic sensor. The synchronous belt is rotationally supported on the driving support frame through a synchronous belt pulley. The first motor is connected to the synchronous belt pulley of the synchronous belt and drives its transmission. The first optoelectronic sensor is used to detect whether the parking spaces in the waiting-to-go area are idle. Among them, the second optoelectronic sensor between the no-vehicle area and the waiting-to-go area is used to calculate the number of movements of the parking racks, thereby judging the vacancy rate of the waiting-to-go area, and transmitting the operating status of the parking lot to the cloud platform through a wireless communication module; the no-vehicle area includes a second motor, a telescopic frame for collecting empty parking spaces, and corresponding hoisting equipment.

[0008] An unlocking button is provided on the parking rack, and the unlocking button is a supplement to the existing vehicle self-locking system; the device housing adopts a house-like design with three-sided walls and one side empty plus a roof, and all the required electricity is provided by the solar panels above the parking lot device.

[0009] A tray base with pulleys is used to store vehicles, and adjacent shared bicycles are connected in a ring and tube combination. The force direction of the ring and tube is changed by the action of its own gravity, thereby changing the parking distance between adjacent vehicles, so that the vehicles in the waiting area are parked closely, and there is enough space in the waiting-to-go area for users to access and park vehicles conveniently.

[0010] The first motor rotates in different directions according to specific circumstances. When the user pushes the vehicle into the corresponding parking rack, the front wheels of the vehicle will trigger the first photoelectric sensor on the parking device, and at the same time, the vehicle will be locked. When the user uses the vehicle, they need to first press the unlock button on the parking rack and then scan the code independently to use the vehicle. When the waiting area is full of vehicles or there are no vehicles, the microprocessor connected to the second photoelectric sensor controls the motor, thereby driving the synchronous belt, and the second photoelectric sensor in the waiting area is used to determine whether the waiting area is full of vehicles. When the waiting area is full of vehicles, the first motor will drive the synchronous belt to rotate towards the waiting area, making the vehicles in the waiting area park closely; when there are no vehicles in the waiting area, the first motor will drive the synchronous belt to rotate towards the no-vehicle area.

[0011] The no-vehicle area uses a vertically telescopic rack to collect empty vehicle parking racks. When the first motor keeps driving the synchronous belt to operate towards the no-vehicle area, the second motor located in the no-vehicle area will also operate, driving the telescopic rack to expand upward, thereby collecting the empty vehicle parking racks in sequence. When the first motor keeps driving the synchronous belt to operate towards the waiting area, the second motor located in the no-vehicle area will also operate, making the telescopic rack move downward and releasing the empty vehicle parking racks in sequence.

[0012] It also includes a wireless communication module. The wireless communication module transmits the operation status information of the parking lot to the cloud platform. The operation and maintenance management personnel can freely enter the user application interface of the cloud platform through the account and password of the cloud platform, with the help of an Internet-connected mobile device or PC, to view the operation status information of the parking lot. At the same time, when there are no vehicles, the parking lot is full, or the parking rack does not reach the specified position within a certain period of time in the parking lot, the system will automatically transmit the abnormal information of the parking lot to the cloud platform through the wireless communication module. While the cloud platform displays the alarm information of the parking lot on the user application interface of the cloud platform, it will also send alarm information about the parking lot being full, having no vehicles, or being abnormal to the operation and maintenance management personnel via text message, email, or WeChat official account.

[0013] A control method for a control device for automatic parking of shared bicycles specifically includes the following steps:

[0014] When the user parks the vehicle in the parking lot:

[0015] Step 1.1: When the user rides the vehicle to the parking space, the front wheels of the vehicle trigger the first photoelectric sensor on the parking space. At the same time as the vehicle locking device is activated, a voice broadcast is triggered to prompt the user to scan the code to lock the vehicle independently.

[0016] Step 1.2: The user scans the vehicle QR code, enabling the vehicle locking device to be activated, and the user completes the use of the vehicle.

[0017] Step 1.3: The system determines whether the waiting area is full of vehicles based on the state of the second photoelectric sensor in the waiting area;

[0018] Step 1.4: If the vehicles in the waiting area are not full, the system goes into sleep mode; if the vehicles in the waiting area are full, the system transmits the information that the parking lot is full to the cloud platform through the wireless communication module. At the same time, the cloud platform will also send an abnormal alarm message indicating that the parking lot is full to the operation and maintenance management personnel via text message, email, or WeChat official account. When the vehicles in the waiting area are not full, the system activates a voice broadcast to prompt users to stay away from the parking lot temporarily and activates the guardrail in front of the waiting area.

[0019] Step 1.5: After activating the guardrail in the waiting area, the first motor drives the synchronous belt, causing the parking spaces in the waiting area to move towards the waiting area direction. At the same time, the empty parking space telescopic frame in the empty vehicle area also moves downward.

[0020] Step 1.6: As the second motor in the waiting area and the empty vehicle area keeps running, the system calculates the number of movements of the parking rack and the empty vehicle rate in the waiting area through the second photoelectric sensor on the left side of the empty vehicle area, and determines whether the empty vehicle rate in the waiting area is the set value. When the empty vehicle rate does not reach the set value, the first motor keeps running. When the empty vehicle rate reaches the set value, it is determined whether the rightmost parking space in the waiting area reaches the rightmost position within a certain period of time. If it reaches the rightmost position, the first motor stops running; otherwise, while the first motor stops running, an abnormal alarm message indicating that the parking rack has not reached the designated position will be sent to the cloud platform.

[0021] Step 1.7: After the motors in the waiting area and the empty vehicle area stop running normally, activate the safety prompt voice broadcast and lower the guardrail in front of the waiting area.

[0022] When the user picks up their vehicle from the parking lot:

[0023] Step 2.1: When the user needs to pick up their vehicle from the parking space, press the unlock button on the parking rack. While the vehicle position lock is unlocked, a voice broadcast prompting the user to scan the code to unlock independently is triggered.

[0024] Step 2.2: The user scans the vehicle QR code to unlock the vehicle locking device, and the user completes vehicle pickup.

[0025] Step 2.3: The system determines whether the vehicles in the waiting area are empty based on the status of the first photoelectric sensor in the waiting area.

[0026] Step 2.4: If the vehicles in the waiting area are not empty, the system goes into sleep mode; if the vehicles in the waiting area are empty, the system transmits the information that the parking lot is empty to the cloud platform through the wireless communication module. At the same time, the cloud platform will also send an abnormal alarm message indicating that there are no vehicles in the parking lot to the operation and maintenance management personnel via text message, email, or WeChat official account. When the vehicles in the waiting area are not empty, the system activates a voice broadcast to prompt users to stay away from the parking lot temporarily and activates the guardrail in front of the waiting area.

[0027] Step 2.5: After activating the guardrail in the waiting area, the first motor drives the synchronous belt, causing the parking spaces in the waiting area to move towards the vehicle-free area. At the same time, the telescopic rack for collecting empty parking spaces in the vehicle-free area will also move upward;

[0028] Step 2.6: As the motors in the waiting area and the vehicle-free area keep running, the system calculates the number of movements of the parking racks and the vacancy rate in the waiting area through the second photoelectric sensor on the left side of the vehicle-free area, and determines whether the vacancy rate in the waiting area is the set value; when the vacancy rate does not reach the set value, the first motor keeps running; when the vacancy rate reaches the set value, it is determined whether the rightmost parking space in the waiting area reaches the rightmost position within a certain time. If it reaches the rightmost position, the first motor stops running; otherwise, while the first motor stops running, an abnormal alarm message indicating that the parking rack has not reached the specified position will be sent to the cloud platform;

[0029] Step 2.7: After the first motor and the second motor in the waiting area and the vehicle-free area stop running normally, activate the safety prompt voice broadcast and lower the guardrail in the waiting area.

[0030] This device combines existing sensing technologies and cloud service technologies. After collecting a large amount of device operation status information, it conducts data analysis on the usage of bicycles in different regions based on this, and further rationally allocates bicycles based on this to improve the utilization rate of bicycles.

[0031] The present invention has the following beneficial effects:

[0032] 1. The connection method combining the ring and the pipe simply and effectively solves the problem of parking spacing, reduces the occupied space, and at the same time simply and effectively achieves the purpose of convenient access for users to park and retrieve bicycles.

[0033] 2. The modularization of the vehicle area, the waiting area, and the vehicle-free area makes the device structure simple and convenient for maintenance, while improving the service life of bicycles and effectively improving the utilization rate of land resources.

[0034] 3. The ingenious mechanical design of the project structure and the application of simple and effective electrical equipment can provide sufficient power demand for this device by using solar panels in daily use, reducing costs while greatly enhancing the feasibility and practicality of the project.

[0035] 4. The design of this device combines existing sensing technologies, cloud service technologies, etc. After collecting a large amount of device operation status information, it can conduct data analysis on the usage of bicycles in different regions based on this, and further rationally allocate bicycles based on this to improve the utilization rate of bicycles.

The first motor 14 is connected to the synchronous belt pulley of the synchronous belt 13 and drives its transmission. The first photoelectric sensor 7 is used to detect whether the parking spaces in the waiting-to-go area 11 are idle. Among them, the second photoelectric sensor 5 between the no-vehicle area 15 and the waiting-to-go area 11 is used to calculate the number of movements of the parking racks 6, so as to judge the empty vehicle rate of the waiting-to-go area 11, and transmit the operating status of the parking lot to the cloud platform through a wireless communication module; the no-vehicle area 15 includes a second motor 2, a telescopic frame 16 for collecting empty parking spaces and corresponding lifting equipment 3. Through the above device, an effective special safety protection place is provided for shared bicycles. On the basis of giving people a more convenient and free use of bicycles, it better maintains the social environment, improves people's vehicle use experience, and continues the development vitality of shared bicycles. By making convenient improvements in the access and storage of shared bicycles, and using the current mature sensor technology and simple mechanical movements to achieve the design goals of the product. On the basis of ergonomics, while realizing the convenient access and parking of vehicles by people, the land resources of the parking lot are utilized to the maximum extent.

[0050] Further, an unlocking button 10 is provided on the parking rack 6, and the unlocking button 10 is a supplement to the existing vehicle self-locking system; the device housing 4 adopts a house-type design with three-sided walls and one side empty plus a roof, and all the required electricity is provided by the solar panels 1 above the parking lot device.

[0051] Further, a pallet base with pulleys is used to store vehicles, and the adjacent two shared bicycles are connected in a ring and tube combination. By the action of its own gravity, the acting direction of the ring and tube is changed, so as to change the parking distance between adjacent vehicles, making the vehicles parked closely in the waiting area and leaving enough space in the waiting-to-go area 11 for users to access the vehicles.

[0052] Further, the first motor 14 rotates in different directions according to specific situations.

When there are no vehicles in the waiting area 11, the first motor 14 will drive the synchronous belt 13 to rotate towards the no-vehicle area 15.

[0053] Further, the no-vehicle area 15 uses a vertically telescopic frame 16 to collect the empty vehicle parking racks. When the first motor 14 keeps driving the synchronous belt 13 to run towards the no-vehicle area, the second motor 2 located in the no-vehicle area 15 will also run, driving the telescopic frame 16 to expand upward to collect the empty vehicle parking racks in sequence.

At the same time, when there are no vehicles, the parking lot is full, or the parking rack 6 does not reach the specified position within a certain period of time in the parking lot, the system will automatically transmit the abnormal information of the parking lot to the cloud platform through the wireless communication module. While the cloud platform displays the alarm information of the parking lot on the user application interface of the cloud platform, it will also send alarm information about the parking lot being full, having no vehicles, or being abnormal to the operation and maintenance management personnel via text message, email, or WeChat official account.

When the waiting area is full of vehicles, the first motor will drive the synchronous belt to rotate towards the waiting area, making the vehicles in the waiting area park closely. At the same time, the second motor above the parking lot will also rotate, driving the rope, making the parking space collection telescopic frame move downward and release the empty parking spaces in sequence; When there are no vehicles in the waiting area, the first motor will drive the synchronous belt to rotate towards the no-vehicle area. At the same time, the second motor above the parking lot will also rotate, driving the rope, making the parking space collection telescopic frame move upward and collect the empty parking spaces in sequence, reducing the floor area of the empty parking spaces.

While the vehicle locking device of the parking space is activated, a voice broadcast is triggered to prompt the user to scan the code to lock the vehicle independently.

[0065] Step 1.2: The user scans the vehicle QR code, enabling the vehicle locking device to be activated, and the user completes the use of the vehicle.

[0066] Step 1.3: The system determines whether the vehicles in the waiting area are full based on the state of the second optoelectronic sensor 5 in the waiting area;

[0067] Step 1.4: If the vehicles in the waiting area 11 are not full, the system goes into sleep mode; if the vehicles in the waiting area are full, the system transmits the information that the parking lot is full to the cloud platform through the wireless communication module; meanwhile, the cloud platform will also send an abnormal alarm message indicating that the parking lot is full to the operation and maintenance management personnel via text message, email, or WeChat official account; when the vehicles in the waiting area are not full, the system activates a voice broadcast to prompt the user to stay away from the parking lot temporarily and activates the protective fence 8 in front of the waiting area;

[0068] Step 1.5: After activating the protective fence 8 in the waiting area 11, the first motor 14 drives the synchronous belt 13, causing the parking spaces in the waiting area 11 to move towards the waiting area 9. Meanwhile, the telescopic frame 16 for collecting empty parking spaces in the empty vehicle area will also move downward;

[0069] Step 1.6: As the second motor 2 in the waiting area 11 and the empty vehicle area 15 keeps running, the system calculates the number of movements of the parking rack 6 and the empty vehicle rate in the waiting area through the second optoelectronic sensor 5 on the left side of the empty vehicle area, and determines whether the empty vehicle rate in the waiting area reaches the set value; when the empty vehicle rate does not reach the set value, the first motor 14 keeps running; when the empty vehicle rate reaches the set value, it is determined whether the rightmost parking space in the waiting area reaches the rightmost position within a certain period of time. If it reaches the rightmost position, the first motor 14 stops running; otherwise, while the first motor 14 stops running, an abnormal alarm message indicating that the parking rack does not reach the specified position will be sent to the cloud platform;

[0070] Step 1.7: After the motors in the waiting area and the empty vehicle area stop running normally, a safety prompt voice broadcast is activated, and the protective fence 8 in front of the waiting area is lowered;

[0071] When the user picks up the vehicle from the parking lot:

[0072] Step 2.1: When the user needs to pick up the vehicle from the parking space, press the unlocking key 10 on the parking rack. While the vehicle lock of the parking space is unlocked, a voice broadcast is triggered to prompt the user to scan the code to unlock the vehicle independently.

[0073] Step 2.2: The user scans the vehicle QR code to unlock the vehicle lock of the vehicle, and the user completes vehicle pickup.

[0074] Step 2.3: The system determines whether the vehicle in the waiting area is empty by the state of the first photoelectric sensor 7 in the waiting area 11.

[0075] Step 2.4: If the vehicle in the waiting area is not empty, the system goes to sleep; if the vehicle in the waiting area is empty, the system transmits the information that the vehicles in the parking lot are empty to the cloud platform through the wireless communication module. At the same time, the cloud platform will also send an abnormal alarm message of no vehicle in the parking lot to the operation and maintenance management personnel via SMS, email or WeChat public account; when the vehicle in the waiting area is not empty, the system starts a voice broadcast to prompt the user to stay away from the parking lot temporarily and activates the protective fence in front of the waiting area.

[0076] Step 2.5: After activating the protective fence in the waiting area, the first motor 14 drives the synchronous belt 13 to move the parking spaces in the waiting area towards the no-vehicle area.

When the empty vehicle rate does not reach the set value, the first motor 14 keeps running; when the empty vehicle rate reaches the set value, it is determined whether the rightmost parking space in the waiting area reaches the rightmost position within a certain time. If it reaches the rightmost position, the first motor stops running; otherwise, while the first motor stops running, an abnormal alarm message that the parking rack does not reach the specified position will be sent to the cloud platform.

[0078] Step 2.7: After the first motor 14 and the second motor 2 in the waiting area and the no-vehicle area stop running normally, a safety prompt voice broadcast is activated, and the protective fence in the waiting area is lowered.

[0079] This device combines existing sensing technologies and cloud service technologies.

The operation and maintenance management personnel can freely enter the user application interface of the cloud platform through the account and password of the cloud platform, with the help of an Internet-connected mobile device or PC, to view the operation status information of the parking lot. Meanwhile, when there are no vehicles, the parking lot is full, or the parking rack (6) fails to reach the specified position within a certain period of time in the parking lot, the control device will automatically transmit the abnormal information of the parking lot to the cloud platform through the wireless communication module. While the cloud platform displays the alarm information of the parking lot on the user application interface of the cloud platform, it will also send alarm information about the parking lot being full, having no vehicles, or being abnormal to the operation and maintenance management personnel via text message, email, or WeChat official account.

7. The control method of a control device for automatic parking of shared bicycles according to any one of claims 1-6, characterized in that Specifically, it includes the following steps: When the user parks the vehicle in the parking lot: Step 1.1: When the user rides the vehicle to the parking space, the front wheel of the vehicle triggers the first optoelectronic sensor (7) on the parking space. While the parking space locking device is activated, a voice broadcast is triggered to prompt the user to scan the code to lock the vehicle independently. Step 1.2: The user scans the vehicle QR code, enabling the vehicle locking device to be activated, and the user completes the use of the vehicle. Step 1.3: The control device determines whether the vehicles in the waiting area are full based on the status of the second optoelectronic sensor (5) in the waiting area. Step 1.4: If the vehicles in the waiting area (11) are not full, the control device goes into sleep mode; if the vehicles in the waiting area are full, the control device transmits the information that the parking lot is full of vehicles to the cloud platform through the wireless communication module. Meanwhile, the cloud platform will also send an abnormal alarm message about the parking lot being full to the operation and maintenance management personnel via text message, email, or WeChat official account. When the vehicles in the waiting area are not full, the control device activates a voice broadcast to prompt the user to stay away from the parking lot temporarily and activates the protective fence (8) in front of the waiting area. Step 1.5: After activating the protective fence (8) in the waiting area (11), the first motor (14) drives the synchronous belt (13), causing the parking spaces in the waiting area (11) to move towards the waiting area (9). Meanwhile, the telescopic frame (16) for collecting empty parking spaces in the empty vehicle area will also move downwards. Step 1.6: As the first motor (14) in the waiting area (11) and the second motor (2) in the empty vehicle area (15) keep running, the control device calculates the number of movements of the parking rack (6) and the empty vehicle rate in the waiting area through the second photoelectric sensor (5) on the left side of the empty vehicle area, and determines whether the empty vehicle rate in the waiting area is the set value; when the empty vehicle rate does not reach the set value, the first motor (14) keeps running; when the empty vehicle rate reaches the set value, it is determined within a certain time whether the rightmost parking space in the waiting area reaches the rightmost position. If it reaches the rightmost position, the first motor (14) stops running; otherwise, while the first motor (14) stops running, an abnormal alarm message that the parking rack does not reach the specified position will be sent to the cloud platform. Step 1.7: After the first motor (14) in the waiting area (11) and the second motor (2) in the empty vehicle area (15) stop running normally, start the safety prompt voice broadcast and lower the guardrail (8) in front of the waiting area. When the user picks up the vehicle from the parking lot: Step 2.1: When the user needs to pick up the vehicle from the parking space, press the unlocking button (10) on the parking rack. While the parking space locking device is unlocked, a voice broadcast is triggered to prompt the user to scan the code to unlock the vehicle independently. Step 2.2: The user scans the vehicle QR code to unlock the vehicle locking device, and the user completes picking up the vehicle. Step 2.3: The control device determines whether the vehicles in the waiting area are empty according to the state of the first photoelectric sensor (7) in the waiting area (11). Step 2.4: If the vehicles in the waiting area are not empty, the control device goes into sleep mode. If the vehicles in the waiting area are empty, the control device transmits the information that the vehicles in the parking lot are empty to the cloud platform through the wireless communication module; at the same time, the cloud platform will also send an abnormal alarm message that there are no vehicles in the parking lot to the operation and maintenance management personnel through text messages, emails or WeChat official accounts; when the vehicles in the waiting area are not empty, the control device starts a voice broadcast to prompt the user to stay away from the parking lot temporarily and starts the guardrail in front of the waiting area. Step 2.5: After starting the guardrail in the waiting area, the first motor (14) drives the synchronous belt (13) to move the parking spaces in the waiting area towards the empty vehicle area. At the same time, the telescopic rack (16) for collecting empty parking spaces in the empty vehicle area also moves upward. Step 2.6: As the first motor (14) in the waiting area (11) and the second motor (2) in the empty vehicle area (15) keep running, the control device calculates the number of movements of the parking rack and the empty vehicle rate in the waiting area through the second photoelectric sensor (5) on the left side of the empty vehicle area, and determines whether the empty vehicle rate in the waiting area is the set value; when the empty vehicle rate does not reach the set value, the first motor (14) keeps running; when the empty vehicle rate reaches the set value, it is determined within a certain time whether the rightmost parking space in the waiting area reaches the rightmost position. If it reaches the rightmost position, the first motor stops running; otherwise, while the first motor stops running, an abnormal alarm message that the parking rack does not reach the specified position will be sent to the cloud platform. Step 2.7: After the first motor (14) in the waiting area (11) and the second motor (2) in the empty vehicle area stop running normally, start the safety prompt voice broadcast and lower the guardrail in the waiting area.
