Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent parking lot management, in particular to an intelligent parking space system and a vehicle recognition device. BACKGROUND

[0002] With the rapid popularization of new energy vehicles, the number of electric vehicles continues to grow, and the planning and management of charging parking spaces have become an important challenge for parking lot operation. Currently, traditional parking lots face double contradictions: on the one hand, the phenomenon of oil cars occupying charging parking spaces is widespread, leading to the difficulty of electric car owners "finding a charging pile"; on the other hand, some dedicated charging parking spaces set by the parking lot to prevent occupation are idle when there is no electric car charging, causing the difficulty of oil cars "parking", and intensifying the waste of parking space resources.

[0003] In the prior art, although some anti-occupation devices can block oil cars from entering through mechanical structures, they lack precise vehicle type recognition capabilities - when there is no electric car charging at the charging pile parking space, oil cars are still prevented from occupying the space, which leads to the waste of parking space resources. For example, the anti-occupation device based on license plate recognition proposed in Chinese patent document CN222313870U can identify new energy license plates in real time and automatically trigger the extension of the telescopic rod and the extension block to form a physical barrier, ensuring that the charging pile parking space is always prohibited for oil cars to park.

[0004] In the prior art, traditional anti-occupation devices rely on manual or single mechanical structures and cannot dynamically adjust the occupation strategy according to charging needs, resulting in the parking space remaining closed when there is no electric car charging, which not only limits the use of oil cars but also causes resource idleness. At the same time, existing vehicle type recognition relies on license plate information or appearance features, which has obvious technical limitations: license plate recognition is easily affected by damage and obstruction, leading to misjudgment, and it is more difficult to distinguish between oil-electric vehicles with similar appearances. SUMMARY

[0043] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of the present application and are not used to limit the present application.

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the present application.

[0045] It should be noted that all directional indications, such as upper, lower, left, right, front, back, etc., in the embodiments of the present application are used only to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

[0046] In addition, the description involving "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of a person of ordinary skill in the art, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope claimed by the present application.

[0047] The main solution of the embodiments of the present application is to construct a "chassis feature + license plate information" dual recognition system, and dynamically control the parking space right through the central control module 2 - when the intelligent parking space usage ratio exceeds 70%, the ground lock is automatically locked to refuse the entry of oil cars and trigger the parking space release mechanism; below the threshold, open the oil car parking, realize the intelligent allocation of charging parking space resources. The matching parking space release mechanism can remind the vehicle owner to move the vehicle in stages, combined with the charging state monitoring and overtime alarm function, to improve the parking space utilization rate. The design adapts to different scenes through dynamic weight setting, fundamentally solves the dual contradiction of oil car occupation and resource idling, and provides an innovative scheme for intelligent parking lot which takes into account recognition accuracy and management efficiency.

[0048] It should be noted that, as shown in Figure 4 , the central control module 2 is connected with the license plate recognition module 1 and the ground lock 3. Figure 4The figure is a parking space release mechanism of the application. The parking space release mechanism: when the intelligent parking space usage ratio increases from below 70% to more than 70%, the system processes according to the following rules: push a "parking space is tight" reminder to the electric vehicle owner who is charging, and suggest that he drives away after being fully charged; send a notification to the oil vehicle owner and the electric vehicle owner who occupies the parking space but does not charge or has been fully charged, and inform them that the intelligent parking space is tight and they should enter the ordinary parking space as soon as possible. If the above-mentioned vehicles do not drive away after 15 minutes, the ground lock is automatically locked and the charging mode is started. This mechanism can be selectively closed during the charging low-peak time (such as 23:00-05:00 at night).

[0049] The application provides a solution, and discloses an intelligent parking space system and a vehicle recognition device. The intelligent parking space system is applied to a parking lot. The intelligent parking space system comprises a recognition module 1 and a central control module 2. The central control module 2 is connected with the recognition module 1. The recognition module 1 is used for collecting license plate signals and chassis signals of a vehicle and sending the signals to the central control module 2. The central control module 2 is used for determining a vehicle type according to the license plate signals and the chassis signals of the vehicle. The vehicle type comprises an oil vehicle and an electric vehicle. The central control module 2 is further used for controlling a ground lock in the parking lot to keep an open state when an intelligent parking space usage ratio in the parking lot is lower than a preset threshold value, so that the oil vehicle enters the intelligent parking space of the parking lot to park. By adopting a chassis scanning technology such as a millimeter wave radar or a laser radar, the oil vehicle and the electric vehicle can be accurately distinguished according to physical structure differences such as battery pack layout and chassis component features. This mode is not limited by license plates or appearances, is especially suitable for the recognition of temporary license plate vehicles, foreign vehicles and oil-to-electric vehicles, can provide reliable judgment basis for the anti-occupying device from the essential characteristics of the vehicle, fundamentally solves the misjudgment problem of traditional recognition technologies, ensures that the electric vehicle is allowed to use the intelligent parking space to park at all time periods of the charging parking space, and significantly improves the accuracy and applicability of the anti-occupying system.

[0050] Based on this, the application embodiment provides an intelligent parking space system.

[0051] Reference Figure 1 , Figure 1 The figure is a structure schematic diagram of an intelligent parking space system first embodiment provided by the application embodiment.

[0052] It is considered that the traditional anti-occupying device depends on manual work or a single mechanical structure, and cannot dynamically adjust the occupying strategy according to the charging demand, so that the parking space is still in a closed state when there is no electric vehicle to charge. As shown in Figure 1 The intelligent parking space system described in the embodiment is applied to a parking lot. The intelligent parking space system comprises a recognition module 1 and a central control module 2.

[0053] The central control module 2 is connected with the recognition module 1.

[0054] The recognition module 1 is configured to collect license plate signals and chassis signals of the vehicle and send the signals to the central control module 2.

[0055] The central control module 2 is configured to determine the type of the vehicle according to the license plate signals and the chassis signals of the vehicle, wherein the type of the vehicle includes an oil car and an electric car.

[0056] The central control module 2 is further configured to control ground locks in the parking lot to remain in an open state when a usage proportion of intelligent parking spaces in the parking lot is lower than a preset threshold, so as to enable the oil car to enter the intelligent parking space of the parking lot.

[0057] It should be noted that the recognition module 1 collects license plate images by installing a high-definition camera above a parking space entrance or a charging pile stand, and obtains license plate signals. The recognition module 1 obtains chassis signals by adopting a millimeter wave radar or a laser radar device, and installing a buried radar in front of an intelligent parking space to perform three-dimensional scanning on a vehicle chassis, so as to obtain physical structure data such as a battery pack layout and a transmission component. The accuracy of vehicle recognition is improved by combining the two signals (the license plate signals and the chassis signals).

[0058] It can be understood that parking spaces in the parking lot are divided into ordinary parking spaces and intelligent parking spaces, and the intelligent parking spaces are provided with charging piles and can be used for charging the electric car. When the intelligent parking space is in a state of no vehicle entering, the ground locks in the parking lot remain in a locked state. The preset threshold is a preset intelligent parking space usage threshold. The preset threshold can be 70%, and can also be set according to actual needs, which is not limited in the embodiment.

[0059] In specific implementation, the recognition module 1 is configured to collect license plate signals and chassis signals of the vehicle and send the signals to the central control module 2. The central control module 2 is configured to determine the type of the vehicle according to the license plate signals and the chassis signals of the vehicle, wherein the type of the vehicle includes an oil car and an electric car. The central control module 2 is further configured to control ground locks in the parking lot to remain in an open state when a usage proportion of intelligent parking spaces in the parking lot is lower than a preset threshold, so as to enable the oil car to enter the intelligent parking space of the parking lot. By adopting a chassis scanning technology such as a millimeter wave radar or a laser radar, an oil car and an electric car can be accurately distinguished according to physical structure differences such as a battery pack layout and a chassis component feature. This mode is not limited by license plates or appearances, and is especially suitable for identifying temporary license plate vehicles, foreign vehicles and oil-to-electric vehicles. The mode can provide reliable judgment basis for the anti-occupying device from essential characteristics of the vehicle, fundamentally solves the misjudgment problem of traditional recognition technologies, ensures that the charging parking space is only allowed to be used by the electric car in a full period, and significantly improves the accuracy and applicability of the anti-occupying system.

[0060] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above introduction and will not be described in detail later. Figure 2 , Figure 2 This is a structural diagram of the second embodiment of the intelligent parking system proposed in the embodiments of this application.

[0061] Consider monitoring the charging status of electric vehicles in the parking lot. Figure 2 As shown, the smart parking system of this embodiment further includes: a charging status detection module 3;

[0062] The charging status detection module 3 is connected to the central control module 2 and the electric vehicle;

[0063] The charging status detection module 3 is used to monitor the charging status of the electric vehicles in the parking spaces in the parking lot in real time, and send the number of electric vehicles being charged in the parking lot to the central control module 2 according to the charging status;

[0064] The central control module 2 is further configured to send a parking space shortage signal to the owner of the tram when the usage ratio of the trams in the parking lot is greater than a preset threshold.

[0065] It should be noted that the charging status parameters of an electric vehicle include battery voltage, battery current, battery temperature, battery state of charge (SOC), and charging time. Battery voltage is one of the most important indicators for measuring the battery's energy state. During the charging process, the voltage gradually increases as the battery charge level increases. When the voltage reaches a certain value, the battery is nearly fully charged. The battery current reflects the charging speed. A higher charging current can shorten the charging time, but excessive current may adversely affect the battery life. Battery temperature is crucial to charging efficiency and safety. Both high and low temperatures can affect battery performance and life. During the charging process, the battery generates heat. If the temperature is too high, it may cause thermal runaway, posing a safety risk. The battery state of charge (SOC) is the most intuitive parameter for users to understand the battery status. It helps users determine the vehicle's range and whether it needs to be recharged. Charging time refers to the time it takes for an electric vehicle to charge from the start to the end.

[0066] It is understandable that the preset threshold may be 70%, and may also be set according to actual needs, which is not limited in this embodiment.

[0067] In a specific implementation, a current sensor or a communication interface is arranged at a charging pile of the intelligent parking space to monitor the charging state of a vehicle on the parking space in real time, and the number of electric vehicles being charged in the parking lot is counted and sent to the central control module 2. When the intelligent parking space usage ratio increases from less than 70% to more than 70%, the system processes according to the following rules: the electric vehicle owner being charged is pushed a "parking space shortage (signal)" reminder, and is suggested to leave after being fully charged.

[0068] Further, the charging state detection module 3 is further configured to send a charging completion signal to the central control module 2 when it is detected that the electric vehicle has completed charging.

[0069] The central control module 2 is further configured to send a parking space replacement signal to the electric vehicle owner when the charging completion signal is received.

[0070] It should be noted that when the intelligent parking space is in shortage (when the intelligent parking space usage ratio increases from less than 70% to more than 70%), not only the electric vehicle owners who have been fully charged are sent a parking space replacement signal, but also the owners of oil vehicles and electric vehicles occupying parking spaces but not being charged are sent a parking space signal.

[0071] In a specific implementation, the owners of oil vehicles and electric vehicles occupying parking spaces but not being charged or having been fully charged are sent a notification that the intelligent parking space is in shortage and they should enter the ordinary parking space as soon as possible.

[0072] Further, the central control module 2 is further configured to control the ground lock in the parking lot to remain in a locked state to refuse the oil vehicle to enter the intelligent parking space of the parking lot when the intelligent parking space usage ratio in the parking lot reaches a preset threshold.

[0073] It should be noted that the preset threshold can be 70%, and can also be set according to actual needs, which is not limited in the embodiment. The state of the ground lock in the parking lot includes: a locked state (prohibiting parking) and an open state (allowing parking).

[0074] In a specific implementation, when the intelligent parking space usage ratio reaches 70% of the total intelligent parking space, the ground lock remains in a locked state to refuse the oil vehicle to enter, and a parking space release mechanism is triggered.

[0075] Further, the intelligent parking space system further comprises an execution mechanism module 4.

[0076] The execution mechanism module 4 is connected with the central control module 2.

[0077] The central control module 2 is further configured to send a locking signal to the execution mechanism module 4 when the intelligent parking space usage ratio in the parking lot reaches a preset threshold.

[0078] The execution mechanism module 4 is configured to control the ground lock in the parking lot to keep the locking state when the locking signal is received.

[0079] The execution mechanism module 4 is further configured to send a voice signal to the driver of the vehicle to refuse the vehicle to park in the intelligent parking space of the parking lot when the locking signal is received.

[0080] It should be noted that the execution mechanism module 4 includes an intelligent ground lock, a parking space guiding indicator light, a communication unit, and the like, and performs the functions of parking space locking (locking state) or unlocking (opening state), state display (achieved by an LED indicator light), and data transmission according to the instructions of the central control module 2.

[0081] In a specific implementation, the central control module 2 is further configured to send a locking signal to the execution mechanism module 4 when the use ratio of the intelligent parking space in the parking lot reaches a preset threshold value; the execution mechanism module 4 is configured to control the ground lock in the parking lot to keep the locking state and the LED indicator light to flash red when the locking signal is received; and the execution mechanism module 4 is further configured to send a voice signal to the driver of the vehicle to refuse the vehicle to park in the intelligent parking space of the parking lot when the locking signal is received. Thus, the ground lock can be automatically locked and a warning signal can be sent when the parking space utilization rate of the parking lot reaches the threshold value, and the vehicle is refused to enter, which effectively avoids the over-saturation operation of the parking lot and guarantees the efficient management of the parking lot and the orderly parking of the vehicle.

[0082] Further, the central control module 2 is further configured to send an opening signal to the execution mechanism module 4 when the use ratio of the intelligent parking space in the parking lot is lower than a preset threshold value.

[0083] The execution mechanism module 4 is further configured to control the ground lock in the parking lot to keep the opening state when the opening signal is received.

[0084] It should be noted that the preset threshold value can be 70%, and can also be set according to actual needs, which is not limited in the embodiment.

[0085] In a specific implementation, the central control module 2 is further configured to send an opening signal to the execution mechanism module 4 when the use ratio of the intelligent parking space in the parking lot is lower than a preset threshold value; and the execution mechanism module 4 is further configured to control the ground lock in the parking lot to keep the opening state and the LED indicator light to display yellow when the opening signal is received. Thus, the ground lock can be automatically opened and prompted when the parking space utilization rate of the parking lot is low, which improves the parking space utilization rate and operation efficiency of the parking lot and provides a more convenient parking experience for the vehicle owner.

[0086] Further, the charging state detection module 3 is further configured to enter a charging mode and send a locking signal to the actuator module 4 when the electric vehicle has completed charging and the parking time exceeds a preset time, so that the ground lock of the parking space where the electric vehicle is located is kept in a locked state.

[0087] It should be noted that the preset time can be 15 minutes, and can also be set according to actual needs, which is not limited in the embodiment.

[0088] In a specific implementation, the charging state detection module 3 is further configured to enter a charging mode and send a locking signal to the actuator module 4 when the electric vehicle has completed charging and the parking time exceeds a preset time, so that the ground lock of the parking space where the electric vehicle is located is kept in a locked state, and the ground lock is automatically closed for release after the owner of the electric vehicle pays the fee. Thus, it can effectively prevent the vehicle from occupying the charging pile parking space for a long time without paying the fee, and through the automatic locking and unlocking of the ground lock, the reasonable use of the charging pile parking space is ensured, and the turnover rate and operation efficiency of the parking space are improved.

[0089] Further, the identification module 1 comprises a license plate recognition unit 11 and a chassis scanning recognition unit 12.

[0090] The central control module 2 is connected to the license plate recognition unit 11 and the chassis scanning recognition unit 12, respectively.

[0091] The license plate recognition unit 11 is configured to collect a license plate signal of the vehicle and send the license plate signal to the central control module 2.

[0092] The chassis scanning recognition unit 12 is configured to collect a chassis signal of the vehicle and send the chassis signal to the central control module 2.

[0093] The central control module 2 is further configured to determine a data weight ratio corresponding to the license plate signal and the chassis signal when the license plate signal and the chassis signal are received, so as to determine the type of the vehicle.

[0094] It should be noted that the weight of the license plate and chassis (signal) data is set according to different weight values in different use scenarios. For example, in the charging station scenario, the chassis scanning can directly identify the features such as battery pack and transmission structure, which is the core basis for judging “whether it is a charging vehicle”. The license plate can only confirm the identity of the vehicle, but cannot distinguish the oil-electric vehicle or the unlicensed vehicle, and needs to rely on the chassis features for supplementary verification. Therefore, the weight of the chassis data is set to 60%, and the weight of the license plate data is set to 40%. In the parking lot scenario, the weights of the license plate and chassis data can both be set to 50%. In the unlicensed vehicle high-frequency scenario (test drive vehicle, new vehicle), the weight of the chassis data can be set to 80%, and the weight of the license plate data can be set to 20%.

[0095] In a specific implementation, as shown in Figure 3 the chassis scanning recognition unit 12 is configured to collect a chassis signal of the vehicle and send the chassis signal to the central control module 2.Figure 3 The figure is a schematic diagram of chassis scanning and license plate recognition of the application. When the vehicle drives to the sensing area in front of the parking space, the camera on the charging pile immediately collects the license plate image, analyzes the characters through the OCR algorithm and matches the new energy license plate database, at the same time, the millimeter wave radar or laser radar in front of the parking space performs three-dimensional scanning on the vehicle chassis to obtain the physical structure data of the battery pack layout, transmission components, etc., and transmits to the machine learning model of the central control module 2 to judge the vehicle type. Thus, the vehicle type and key information are quickly and accurately identified, the adaptability and use efficiency of the charging pile are improved, and more intelligent and efficient charging service is provided for new energy vehicles.

[0096] In addition, in order to achieve the above-mentioned purpose, the application further provides a vehicle recognition device, which comprises the intelligent parking space system as described above.

[0097] The above is only the preferred embodiment of the application, and does not limit the patent scope of the application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the application.
