Description

Technical Field

[0001] The present invention relates to the technical field of vehicle parking, and particularly to an intelligent parking device system, a parking method, and a medium. Background Art

[0002] A triangular block, also known as a parking wedge, a wheel stopper, or a parking wedge, is an important device for preventing unnecessary movement of a vehicle. It plays a crucial role in preventing the vehicle from sliding when parking and is an essential part of the vehicle parking protection system. The triangular block has a wide range of applications, especially in places with a certain slope on the ground such as logistics exchange yards, docks, and airports. It is not only used for daily parking but also provides assistance for drivers to solve problems and repair when the vehicle cannot move due to mechanical failures. The triangular block has excellent compressive performance and can effectively prevent the vehicle from sliding when parking. It is an important part of the vehicle parking protection system developed in China in the past thirty-odd years.

[0003] However, in actual applications, there are still some problems in the use and management of triangular blocks. Although the management party usually requires drivers to use triangular blocks after parking, there is a lack of effective management means. Relying solely on manual identification is not only costly but also ineffective. Some parks have adopted the method of requiring drivers to take pictures of the placed triangular blocks and upload them to the platform, but this process is cumbersome and time-consuming. Some drivers may use pictures of triangular blocks of other vehicles or old pictures to cope in order to save trouble.

[0004] To solve this problem, some people have proposed using a camera combined with an AI algorithm to identify whether the triangular block is correctly placed on the vehicle. However, due to many factors such as limited space in the park, small distance between parking spaces, diverse vehicle types, occlusion by adjacent vehicles, and poor installation position of the camera, the camera often cannot capture the placement position of the triangular block at an ideal angle, and sometimes it cannot capture it at all.

[0005] In addition, even if the triangular block is successfully photographed, the AI recognition method may not be able to accurately judge whether the triangular block is placed reasonably. Common problems include incorrect placement direction, inappropriate distance from the tire, etc. These problems will cause the triangular block to fail to play its due role.

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Please refer to Figure 1 , Figure 1 which is the structural diagram of the intelligent parking device system provided by the present invention. As Figure 1 shown, the intelligent parking device system provided by the embodiment of the present invention includes: an ultrasonic ranging sensor (5), an acceleration sensor (2), an electronic compass (3), a communication gateway (14) and a main control unit (1). Among them, the ultrasonic ranging sensor (5) is connected to the main control unit (1) and is used to detect the distance between the parking device and the tire and send the distance signal to the communication gateway; the acceleration sensor (2) is connected to the main control unit (1) and is used to identify the placement posture of the parking device and send the posture signal to the communication gateway; the electronic compass (3) is connected to the main control unit (1) and is used to identify the placement direction of the parking device and send the direction signal to the communication gateway; the communication gateway (14) is connected to the main control unit (1) and is used to receive the data signals sent by the ultrasonic ranging sensor, acceleration sensor and electronic compass in the parking device and transmit the data information to the main control unit; the main control unit is used to receive the data signals and process the data signals.

[0033] In this embodiment, the distance between the parking device and the tire is detected by the ultrasonic ranging sensor to ensure a proper placement position; the placement posture of the parking device is identified by the acceleration sensor to ensure a correct posture; the placement direction of the parking device is identified by the electronic compass to ensure a correct direction; the data of each sensor is received and transmitted by the communication gateway; the data is processed and analyzed by the main control unit. Through the collaborative work of these technical features, the system can monitor and adjust the placement state of the parking device in real time to ensure the safety of the vehicle during parking.

[0034] Specifically, as Figure 2As shown, the device is roughly divided into five working states: idle state, placement detection state, correct placement state, abnormal placement state, and homing detection state. In the idle state, the device can be placed upright, upside down, on its side, or tilted. In the placement detection state, the device is moved and then placed flat after stopping. In this state, multiple sensors need to be detected to determine whether the device is placed correctly. In the correct placement state, the device is placed flat, and the tire fitting distance is appropriate, and the parking space indicator tape can be detected. In the abnormal placement state, the device is placed flat, but the tire fitting distance is too large, or the placement direction is incorrect, or the parking space indicator tape is not detected, or the parking space beacon is not received, etc. In the homing detection state, in the case of the correct placement state and the abnormal placement state, when the detection device is moved, it is determined whether to enter the idle state or stay in the original state according to the device posture.

[0035] Through the detection and recognition of these states, the intelligent parking device system of the present application can provide higher safety and convenience when the vehicle is parked. Through the collaborative work of multiple sensors and the main control unit, the present application realizes the real-time monitoring and adjustment of the placement state of the parking device, avoiding the high cost and low efficiency of manual management, overcoming the cumbersome and unreliable problems of the photo-upload method, and solving the problems of the camera plus AI algorithm method limited by factors such as shooting angle and environment.

[0036] In summary, the intelligent parking device system of the present application realizes the real-time monitoring and adjustment of the placement state of the parking device through the collaborative work of ultrasonic ranging sensors, acceleration sensors, electronic compasses, cameras, communication gateways, and main control units, ensuring the safety of the vehicle when parked, solving many problems in the prior art, and having remarkable innovation and practicality.

[0037] Furthermore, in the intelligent parking device system, the ultrasonic ranging sensor (5) is specifically used to detect the placement distance between the parking device and the tire, determine whether the placement distance conforms to the distance placement rule, and send the distance signal to the communication gateway.

[0038] In this embodiment, the ultrasonic ranging sensor is used to detect the placement distance between the parking device and the tire, determine whether the placement distance conforms to the distance placement rule, and send the distance signal to the communication gateway. In this way, the ultrasonic ranging sensor can monitor the placement distance of the parking device in real time and send a signal when it does not conform to the rule, so as to ensure that the placement distance of the parking device meets the requirements and avoid the phenomenon of vehicle landslide when parking. The ultrasonic distance sensor is used to identify whether the parking device is placed under the wheel and whether the distance from the wheel is compliant. The ultrasonic ranging sensor is used to monitor the distance between the parking device and the tire. In order to reduce power consumption, the ultrasonic sensor is only turned on when needed and remains in a sleep state at other times.

[0039] Specifically, the ultrasonic ranging sensor can measure the distance between the parking device and the tire by emitting ultrasonic signals and receiving the reflected signals. The sensor can be integrated at the bottom or side of the parking device for easy distance detection. To achieve low power consumption, the sensor can be set to only turn on when the vehicle is detected to be approaching and remain in a dormant state at other times. The distance signal detected by the sensor is transmitted to the main control unit through the communication gateway. The main control unit makes a judgment based on the received distance signal and issues an alarm or prompt when the rules are not met.

[0040] By introducing the ultrasonic ranging sensor, this application can monitor the placement distance between the parking device and the tire in real time and send a signal when the distance placement rule is not met. This method can not only ensure that the placement distance of the parking device meets the requirements, avoid the phenomenon of vehicle landslide when parking, but also reduce the manual management cost and improve the management efficiency. Compared with the prior art, this application provides a more intelligent and efficient solution, which can significantly improve the safety and reliability of vehicle parking.

[0041] Further, in the intelligent parking device system, the acceleration sensor (2) is specifically used to identify the placement posture of the parking device, judge whether the placement posture conforms to the posture placement rule, and when the placement posture does not conform to the posture placement rule, send the posture signal to the communication gateway.

[0042] In this embodiment, the acceleration sensor is used to detect the placement posture of the parking device and judge whether the posture conforms to the preset posture placement rule. If the rule is not met, the acceleration sensor will send the detected posture signal to the communication gateway. In this way, the system can automatically identify and correct incorrect placement postures, thereby improving the placement accuracy and safety of the parking device. The acceleration sensor recognizes that the parking device has been moved: then wakes up, recognizes the placement, plays a prompt voice, etc. The acceleration sensor can recognize the acceleration of three axes, thereby judging the posture of the parking device, such as flat placement, side placement, upright placement, etc. Only when placed flat (the contact surface is parallel to the ground) can it be determined that the parking device may be correctly placed.

[0043] The acceleration sensor can be implemented in various ways. For example, a MEMS acceleration sensor can be used. This sensor has the advantages of small size, low power consumption, and low cost. The acceleration sensor can be integrated inside the parking device, and the triaxial acceleration values can be calculated in real time through the built-in algorithm, and the placement posture can be judged according to the preset posture placement rule. When a posture that does not conform to the rule is detected, the acceleration sensor will send the posture signal to the communication gateway through the wireless communication module. After receiving the posture signal, the communication gateway further transmits the signal to the main control unit, and the main control unit can trigger the corresponding prompt or alarm device according to the received signal to remind the user to adjust the placement posture of the parking device.

[0044] Through the application of an acceleration sensor, this application realizes the automatic recognition and monitoring of the placement posture of the parking device, and solves the problems of low accuracy and low efficiency in relying on manual judgment in traditional methods. Compared with the prior art, the technical solution of this application can detect the placement posture of the parking device in real time and accurately, and issue a warning in time when it does not conform to the rules, improving the use safety and reliability of the parking device.

[0045] Furthermore, in the intelligent parking device system, the electronic compass (3) is specifically used to identify the placement direction of the parking device, determine whether the placement direction conforms to the direction placement rule, and when the placement posture does not conform to the posture placement rule, send the direction signal to the communication gateway.

[0046] In this embodiment, the electronic compass identifies the placement direction of the parking device, determines whether it conforms to the direction placement rule, and sends a direction signal to the communication gateway when it does not conform. Through the identification and judgment of the electronic compass, the monitoring of the placement direction of the parking device is realized to ensure that it conforms to the direction placement rule. When it does not conform, by sending a signal to the communication gateway, the user is reminded to correct the placement direction, thereby improving the safety and reliability of the parking device. The electronic compass has a 3-axis electronic compass function and can be used to identify the placement orientation of the parking device. For example, in a north-south parking space, the parking device is considered to be placed correctly when it is placed in the east-west direction.

[0047] The implementation methods of the electronic compass include but are not limited to the following: it can be realized through a 3-axis electronic compass module integrated inside the parking device, or an external electronic compass sensor can be used to communicate with the parking device through wired or wireless means. In addition, the electronic compass can have an automatic calibration function to ensure accuracy in different environments. As a preferred implementation method, the electronic compass can also be combined with a GPS module to provide more accurate direction recognition capabilities.

[0048] This application realizes the effective monitoring of the placement direction of the parking device by using the technical means of the electronic compass to identify the placement direction of the parking device and determine whether it conforms to the direction placement rule. Compared with the prior art, this application can automatically identify and correct the placement direction of the parking device, improve the safety and reliability of the parking device, and avoid potential safety hazards caused by improper placement directions. Thus, this application provides an intelligent solution, improving the use effect and user experience of the parking device.

[0049] Further, for the intelligent parking device system, the communication gateway specifically includes short-range communication (9) and long-range communication (8). The communication gateway is configured to receive the signals of the short-range beacon and the data signals sent by the ultrasonic ranging sensor, the acceleration sensor, and the electronic compass in the parking device, and send the short-range beacon signals and the data signals to the main control unit; the long-range communication is used to transmit the data information processed by the main control unit to the background system.

[0050] In this embodiment, the communication gateway includes two parts: short-range communication and long-range communication. The communication gateway receives the short-range beacon signals and the data signals from the ultrasonic ranging sensor, the acceleration sensor, and the electronic compass, and sends these signals to the main control unit. In addition, the short-range beacon receiving circuit identifies the triangular placement position and whether it returns to its original position after use. The long-range communication part transmits the data information processed by the main control unit to the background system.

[0051] Further, the function of the short-range communication part is to receive the short-range positioning beacon of the parking space to determine the parking space, while the function of the long-range communication part is to ensure the data transmission between the main control unit and the background system. The long-distance communication circuit is used to transmit data back and for anti-theft (the parking device periodically sends a beacon disappearance signal). The long-range communication is used for the parking device to send information to the background through the gateway. In some cases where there is no strict need to distinguish the communication distance, only one of the long-range communication and the short-range communication can be used, or the transmission distance can be controlled by using different transmission powers, data rates, and modulation methods, etc. For the case where the beacon needs to be identified, the distance between the parking device and the beacon can be confirmed by the signal strength, rather than simply determining whether they are nearby by whether the signal is received. Through the cooperation of the short-range communication and the long-range communication, the data transmission problem of the parking device in different communication ranges is solved.

[0052] The implementation method of the short-range communication part can include using short-distance wireless communication technologies such as low-power Bluetooth, Wi-Fi, or Zigbee, which can achieve efficient data transmission in a small range. The long-range communication part can adopt long-distance communication technologies such as cellular networks (such as 4G, 5G) or LoRa to ensure that the parking device can perform data interaction with the background system in a long-distance range. The design of the communication gateway can be adjusted according to the specific application scenario. For example, in some scenarios that require high data rates, Wi-Fi or cellular networks are preferably used, while in some scenarios with high power consumption requirements, Bluetooth or LoRa is preferably used.

[0053] By introducing the integration of short - range communication and long - range communication, this application solves the data transmission problem of the parking device within different communication ranges. Compared with the prior art, the advantages of this application are that it can maintain efficient data transmission in both short - distance and long - distance communication modes, and can flexibly select communication technologies according to specific application scenarios, thus improving the applicability and reliability of the parking device. Especially in the case where beacons need to be identified, the distance between the parking device and the beacon is confirmed through signal strength, further improving the accuracy and stability of data transmission.

[0054] Furthermore, for the intelligent parking device system, the main control unit is specifically configured to receive the short - range beacon signal and data signal sent by the short - range communication;

[0055] analyze and process the short - range beacon signal and data signal to generate data information;

[0056] send the data information to the long - range communication and voice prompt component.

[0057] In this embodiment, the main control unit receives the short - range beacon signal and data signal, analyzes and processes them to generate data information. Then, these data information are sent to the long - range communication and voice prompt component. In this way, the problem of how to process and transmit the short - range beacon signal and data signal is solved, thereby improving the efficiency and reliability of the intelligent parking device system.

[0058] Specifically, the main control unit can receive the short - range beacon signal and data signal through the built - in short - range communication module. After receiving the signal, the main control unit analyzes and processes these signals, extracts useful information and generates data information. The generated data information can be sent to the background system through the long - range communication module, or real - time feedback can be provided to the user through the voice prompt component. For example, when it is detected that the vehicle has not placed the warning triangle correctly, the system can remind the driver to make adjustments through voice prompts.

[0059] This application can effectively process and transmit short - range beacon signals and data signals by introducing the main control unit. Through the analysis and processing of the main control unit, the accuracy and real - time performance of signal processing are improved; secondly, by using the long - range communication and voice prompt component, remote transmission and real - time feedback of data information are realized, enhancing the intelligence of the system and the user experience. Thus, this application significantly improves the efficiency and reliability of the intelligent parking device system and solves the problem of processing and transmitting short - range beacon signals and data signals existing in the prior art.

[0060] Furthermore, the intelligent parking device system further includes a voice prompt component (13), and the voice prompt component is connected to the main control unit and is used to receive the data information transmitted by the main control unit and output modification opinions according to the data information.

[0061] In this embodiment, the voice prompt component is used to receive the data information transmitted by the main control unit and output modification opinions according to these data information. This technical feature is fed back to the user in the form of voice prompts, enabling the user to timely understand the status of the parking device and make adjustments according to the prompts, thus solving the problem of providing effective modification opinions. By adding a voice prompt component to the intelligent parking device system, the system can feed back the data information processed by the main control unit to the user in voice form. This method not only improves the user's information acquisition efficiency but also gives modification opinions in a timely manner when problems are found, helping the user quickly adjust the status of the parking device to ensure the safety and accuracy of parking. Voice prompt: Please put the parking device back to its original position after use. Adjust it if the placement is not standard.

[0062] The voice prompt component can adopt existing voice synthesis technology and transmit the voice prompt to the user through a speaker. Specifically, the voice prompt component can include one or more microphones for capturing ambient sounds and analyzing them through a signal processing unit to ensure the clarity and accuracy of the voice prompt. As a preferred implementation manner, the voice prompt component can also include a storage unit for storing pre-recorded voice prompt information and playing it when needed. Further, the voice prompt component can work in cooperation with other sensors. For example, when it detects that the parking device is not placed correctly, it immediately issues a voice prompt to remind the user to make adjustments.

[0063] By adding a voice prompt component, this application can provide real-time feedback during the user operation process, avoiding the limitations of relying on visual inspection and manual adjustment in traditional methods. Thus, the user can more efficiently complete the placement operation of the parking device, reduce the possibility of misoperation, and improve the intelligent level and user experience of the system. Compared with the prior art, the technical solution of this application significantly improves the usability and safety of the parking device.

[0064] Further, the intelligent parking device system further includes a camera component (4). The camera component is connected to the main control unit and is used to obtain the parking space identifier and transmit the parking space information to the main control unit.

[0065] In this embodiment, the camera assembly acquires the parking space identifier and transmits the parking space information to the main control unit, solving the problem of identifying the parking space identifier and transmitting the parking space information. After receiving the parking space information, the main control unit can further process this information. Through the mutual cooperation of these technical features, the function of automatically identifying the parking space identifier and transmitting the parking space information is realized. During installation, the camera is located on the right side of the parking device, and the camera is tilted at a certain angle towards the ground during installation, which can ensure that after the parking device is placed, the camera can take pictures of the parking space indication tape area, acquire the parking space identifier through the camera assembly, and transmit the parking space information to the main control unit.

[0066] Further, the camera and the fill light circuit are used to take pictures of the parking space indication tape, and the warning light and the horn are used to provide users with sound and light prompts. It also includes low-frequency excitation to wake up the parking device using a low-frequency signal. A typical transmission frequency is, for example, 120KHz, and the actual operating frequency can be adjusted within a certain range. The low-frequency wake-up can use a buried large loop coil to cover the specified area, and the received range can be controlled by the transmission power. The device is powered by a battery and uses a low-power power management system. All circuits are designed with low power consumption, and each part of the circuit is controlled by software to be turned on as needed to accurately control the power consumption.

[0067] Specifically, the implementation method of the camera assembly can be diverse. Specifically, the camera assembly can include a high-resolution camera to ensure that the parking space identifier can be clearly captured under different lighting conditions. Further, in order to enhance the imaging effect, an infrared camera can be equipped to enable normal operation at night or in an environment with insufficient light. The fill light circuit can use an LED lamp group to ensure sufficient light in the shooting area. The camera assembly can also integrate an image processing unit to process the captured images in real time, thereby improving the recognition efficiency. The installation position of the camera assembly can be adjusted according to actual needs, such as being installed above or on the side of the parking space to obtain the best shooting angle.

[0068] This application realizes the function of automatically identifying the parking space identifier and transmitting the parking space information through the combination of various components such as the camera and the main control unit, improving the automation degree of parking space information acquisition, reducing the need for manual intervention, and thus improving the efficiency and accuracy of the system. Further, through low-frequency excitation and low-power design, the stability and durability of the system are ensured, thereby meeting the requirements in practical applications.

[0069] Specific Embodiment 1: How to identify which parking space uses the parking device by using a positioning beacon or a buried positioning excitation coil. By using a buried positioning beacon or a positioning excitation coil to send a signal with a parking space number, the parking device determines the parking space it is in by receiving these signals.

[0070] Such as Figure 3As shown, within the range where the parking device may be placed, multiple positioning beacons or buried positioning excitation coils are buried in the ground. These beacons or coils regularly send signals carrying the parking space number. Each beacon or coil corresponds to a specific parking space, and the signal contains the number information of that parking space.

[0071] When the parking device is placed under the wheels and stationary, it activates the beacon or low-frequency receiving function. The received signal contains the parking space number, and the parking device determines which parking space it is placed in based on the received parking space number. The parking device sends the identified parking space number to the communication gateway, and the gateway then transmits the information to the background system for further processing, such as recording usage and monitoring the status of the parking space. If the parking device receives signals from beacons or coils of adjacent parking spaces simultaneously, it can determine which parking space is closer by comparing the signal strengths. The stronger the signal strength, the closer the distance to that parking space. To reduce interference from signals of adjacent parking spaces, a receiving antenna can be installed on the inner end face of the parking device (i.e., the face opposite the handle), and through design, the receiving sensitivity of the antenna towards the inside is made higher. In this way, the parking device is more likely to receive signals from its own parking space and is relatively less sensitive to signals from adjacent parking spaces.

[0072] Through this solution based on positioning beacons or buried positioning excitation coils, the intelligent parking system can accurately monitor and manage the usage of parking spaces, providing strong technical support for the operation of the parking lot.

[0073] Specific Embodiment 2: How to identify which parking space the parking device is used in through a parking space indicator strip. Use the indicator strip (color strip or identifier) set on the parking space to identify the parking space where the parking device is located. The camera captures an image of the indicator strip and determines the parking space number through an image recognition algorithm.

[0074] As Figure 4 shown, in the central position within the range where the parking device may be placed, 2 color strips (it can also be 1, 3, or more) are painted as parking space indicator strips. The width of these color strips can be less than the width of the parking space, as long as the camera can identify them. Using 2 combinations of 5 non-confusing colors (red, yellow, blue, black, white) can distinguish 10 parking spaces. For example, the red-yellow combination represents parking space 1, the red-blue combination represents parking space 2, and so on. If more parking spaces need to be distinguished, the number of color types can be increased or the number of color strips can be increased to obtain more parking space identification combinations.

[0075] After the parking device is placed under the wheel and stationary, turn on the camera once. The viewing range of the camera should cover the parking space indicator tape to capture the color combination image of the indicator tape. Through the image recognition algorithm, identify the combination of color bands, and combine with the usage range of the parking device to determine the parking space number where the parking device is located. Send the identified parking space number to the communication gateway, and the gateway then transmits the information to the background system for further processing.

[0076] In addition to color bands, the parking space indicator tape can also use a combination of letters, numbers, and symbols to distinguish parking spaces. At this time, the camera uses a pattern recognition algorithm to identify these identifiers to distinguish different parking spaces. Compared with color bands, the method of using identifiers has a slightly higher printing cost, but it can provide more parking space recognition combinations and higher recognition accuracy. Through the solution of using the parking space indicator tape, the intelligent parking system can accurately identify and manage the usage of parking spaces at a lower cost. When the indicator tape is partially damaged or faded after long-term use, it has a higher recognition rate than other methods and is applicable to parking lots of various scales and types.

[0077] Specific Embodiment 3: How to use wireless beacons to identify a unique parking space when there are a large number of parking spaces and the parking space indicator tape cannot distinguish all parking spaces. As Figure 5 and 6 shown, by deploying multiple wireless beacons in the parking lot, each beacon covers a certain range of parking spaces, and the unique parking space where the parking device is located is accurately identified through the coverage overlap and signal strength of the beacon signals.

[0078] Method 1: Deploy multiple wireless beacons (such as S1, S2, S3, etc.) in the parking lot. Each beacon emits signals outward at a certain frequency, and the signal strength covers 6 to 12 parking spaces. The coverage range of the beacon not only depends on whether the parking device can receive the signal, but can also be more accurately determined by the strength of the received signal and the ranging between the beacon and the parking device. The information of its coverage area is carried in the signal sent by each beacon. For example, beacon S2 covers A5 - A10, B1 - B6, and beacon S3 covers A10, B1 - B10, C10, etc. When the parking device is placed in a certain parking space (such as #B6), the camera first identifies the color of the parking space indicator tape to determine that the parking space serial number is 6. The parking device turns on the beacon scan and receives the beacon signals covering this parking space (such as S2 and S3). By identifying the coverage overlap area of the received beacons, the parking device can determine that it is in the #B6 parking space, rather than the #A6 or #C6 parking space.

[0079] Method 2: The beacon only sends its own number (such as S1, S2, etc.), without directly carrying the coverage area information. The background service stores the coverage areas of different beacons and the parking space numbers corresponding to different color combinations. After the parking device is placed, it only sends the color of the parking space indicator tape and the received beacon number. The background service calculates and determines the specific parking space number based on the received information.

[0080] By combining the identification methods of wireless beacons and parking space indicator tapes, the intelligent parking system can accurately monitor and manage the usage of parking spaces in a complex parking lot environment, providing strong technical support for the operation of the parking lot.

[0081] As Figure 7 shown, an embodiment of the present invention also provides an intelligent parking method, which specifically includes:

[0082] S100. Obtain the distance information, direction information, and attitude information of the parking device;

[0083] S200. Respectively determine whether the distance information, direction information, and attitude information conform to the placement rules;

[0084] S300. When any one of the distance information, direction information, and attitude information does not conform to the placement rules, analyze and process the distance information, direction information, and attitude information to generate data information;

[0085] S400. Generate a modification opinion according to the data information.

[0086] In this embodiment, by obtaining the distance information, direction information, and attitude information of the parking device and respectively determining whether these information conform to the placement rules, situations that do not conform to the placement rules can be discovered in a timely manner. When it is detected that any one of the information does not conform to the placement rules, the system will analyze and process this information to generate data information, and generate corresponding modification opinions according to these data information, so as to guide the user to adjust the placement of the parking device to ensure that it conforms to the placement rules, achieving the purpose of preventing unnecessary movement of the vehicle.

[0087] Specifically, obtaining the distance information of the parking device can be achieved through an ultrasonic ranging sensor, which can detect the distance between the parking device and the tire and send the distance signal to the main control unit. The direction information can be obtained through an electronic compass, which can identify the placement direction of the parking device and send the direction signal to the main control unit. The attitude information can be obtained through an acceleration sensor, which can identify the placement attitude of the parking device and send the attitude signal to the main control unit. After receiving these information, the main control unit will analyze and process them to generate data information and generate modification opinions according to the data information.

[0088] For example, an ultrasonic ranging sensor can be installed at the bottom of the parking device to measure the distance between the parking device and the tire by emitting and receiving ultrasonic waves. When it is detected that the distance does not conform to the placement rule, the system generates data information and gives the user a suggestion to adjust the distance through the voice prompt component. An electronic compass can be installed inside the parking device to determine the direction of the parking device by measuring the geomagnetic field. When it is detected that the direction does not conform to the placement rule, the system generates data information and gives the user a suggestion to adjust the direction through the voice prompt component. An acceleration sensor can be installed inside the parking device to determine the attitude of the parking device by measuring the acceleration. When it is detected that the attitude does not conform to the placement rule, the system generates data information and gives the user a suggestion to adjust the attitude through the voice prompt component.

[0089] Accordingly, the present application provides an intelligent parking method. By obtaining the distance information, direction information, and attitude information of the parking device, and respectively determining whether these information conform to the placement rules, situations that do not conform to the placement rules can be discovered in a timely manner. When it is detected that any one of the information does not conform to the placement rule, the system analyzes and processes this information, generates data information, and generates corresponding modification opinions based on this data information, so as to guide the user to adjust the placement of the parking device to ensure that it conforms to the placement rules, achieving the purpose of preventing unnecessary movement of the vehicle, being able to detect the placement situation of the parking device more accurately and timely, and guiding the user to adjust the placement of the parking device by generating modification opinions, having higher practicability and reliability.
