Detailed implementation manners

[0041] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0042] Referring to Figure 1 , a vehicle-mounted parking inspection device provided by the present utility model includes an inspection vehicle and an inspection device. The inspection vehicle in this embodiment is an electric vehicle, and the inspection device is installed on the inspection vehicle. The inspection device includes a geomagnetic reception status module 10, a plurality of image acquisition components 20, a positioning module 30, a main control module 40, a storage module 50, a first mounting bracket 60, a buck module 70, a communication module, and a voice broadcast module 90.

[0043] The geomagnetic reception status module 10 is used to receive the vehicle entry signal sent by the geomagnetic transmission module in the on-street parking berth. A geomagnetic transmission module, that is, a geomagnetic sensor, is installed in the on-street parking berth. Since the metal mass of the vehicle is different from the surrounding environment, it will cause changes in the geomagnetic field. The geomagnetic sensor senses this change and uses principles such as the magnetoresistive effect or the Hall effect to convert the magnetic field change into an electrical signal, and then judges the presence and parking status of the vehicle. When a vehicle enters the target berth, the geomagnetic reception status module 10 of this embodiment receives the electrical signal - the vehicle entry signal sent by the geomagnetic sensor at the target berth, and forwards the vehicle entry signal to the main control module 40, so that the main control module 40 records the vehicle entry time.

[0044] Such as Figure 2As shown, after the inspection vehicle 200 arrives at the target berth, it is necessary to collect images from multiple angles such as the front end and the rear end of the target berth. The multiple image acquisition components 20 in this embodiment are used to collect images from multiple shooting angles to collect vehicle image information and parking berth image information in the on-street parking berth; among them, the multiple angles at least include the front and the rear. Here, the front and the rear refer to the front and the rear of the inspection vehicle 200. As Figure 2 shown, when the inspection vehicle arrives at the rear end of the target berth, it collects images of the area in front of the inspection vehicle, that is, the images of the rear end of the target berth and the rear end of the parked vehicle; when the inspection vehicle arrives at the front end of the target berth, it collects images of the area behind the inspection vehicle, that is, the images of the front end of the target berth and the front end of the parked vehicle.

[0045] Preferably, as Figure 4 shown, each image acquisition component includes a camera 21 and a fill light 22, and the setting of the fill light 22 is suitable for use when the light is dim at night.

[0046] Furthermore, as Figure 3 shown, the multiple image acquisition components 20 include a first image acquisition component, a second image acquisition component, and a third image acquisition component. Among them, the first image acquisition component is installed on the first mounting bracket. The first image acquisition component includes a connected first camera 201 and a first fill light 202, and is used to collect images in front of the inspection vehicle; the second image acquisition component is installed on the first mounting bracket. The second image acquisition component includes a connected second camera 203 and a second fill light 204, and is used to collect images on the left side or the right side of the inspection vehicle; the third image acquisition component is installed on the second mounting bracket. The third image acquisition component includes a connected third camera 205 and a third fill light 206, and is used to collect images behind the inspection vehicle.

[0047] In some possible embodiments, the multiple image acquisition components further include a fourth image acquisition component, a fifth image acquisition component, and a sixth image acquisition component. The fourth image acquisition component is installed on the first mounting bracket. The fourth image acquisition component includes a connected fourth camera 207 and a fourth fill light 208, and is used to collect images on the right side of the inspection vehicle. The fifth image acquisition component is installed on the second mounting bracket. The fifth image acquisition component includes a connected fifth camera 209 and a fifth fill light 210, and is used to collect images on the left side of the inspection vehicle. The sixth image acquisition component is installed on the second mounting bracket. The sixth image acquisition component includes a connected sixth camera 211 and a sixth fill light 212, and is used to collect images on the right side of the inspection vehicle.

[0048] Preferably, the device of this embodiment further includes an Ethernet switch. If the number of interfaces of the Ethernet switch can meet the usage requirements of six image acquisition components, only one Ethernet switch can be set; if the number of interfaces of one Ethernet switch cannot meet the usage requirements of six image acquisition components, multiple Ethernet switches can be set. For example, two Ethernet switches are set, namely the first Ethernet switch 86 and the second Ethernet switch 85 which are connected. The first Ethernet switch 86 is connected to the main control module 40 through an Ethernet interface 84. Among them, the first Ethernet switch 86 is respectively connected to the first camera 201, the second camera 203 and the third camera 205, and the second Ethernet switch 85 is respectively connected to the fourth camera 207, the fifth camera 209 and the sixth camera 211. In addition, the first Ethernet switch 86 is connected to the main control module 40 through an Ethernet interface 84, and the model of the Ethernet interface 84 can be RTL8211.

[0049] In this embodiment, two mounting brackets are provided, namely the first mounting bracket and the second mounting bracket. The first mounting bracket is arranged at the front of the inspection vehicle, and the second mounting bracket is arranged at the rear of the inspection vehicle. Three groups of image acquisition components are installed on each mounting bracket; when the inspection vehicle approaches the rear end of the target parking space, the image acquisition components on the first mounting bracket start to capture the rear end of the target berth and the rear end of the parked vehicle; when the inspection vehicle leaves the target berth, the image acquisition components on the second mounting bracket capture the front end of the target berth and the front end of the parked vehicle; in this way, the image acquisition components can perform image acquisition in the first time, improving the shooting efficiency. As Figure 4 shown, the first mounting bracket includes a base 62 and a screw 61, and the base 62 is fixed on the electric vehicle. A nut 23 adapted to the screw 61 is respectively fixed on each camera, and the camera is installed on the first mounting bracket by threaded connection. The threaded connection mode between the screw 61 and the nut 23 facilitates the adjustment of the angle of the camera 21. No matter which angle the camera 21 is adjusted to, it can be safely and firmly fixed on the screw 61. And multiple cameras 21 can be connected to the screw 61 as needed. Preferably, as Figure 4 shown, the second image acquisition component and the fourth acquisition component installed on the first mounting bracket are arranged oppositely, and respectively collect the images on the left side and the right side of the inspection vehicle. In this way, no matter whether the target berth is on the left or right side of the inspection vehicle, the shooting can be completed without turning the vehicle head. Similarly, the fifth image acquisition component and the sixth acquisition component installed on the second mounting bracket are arranged oppositely, also achieving the purpose of avoiding the inspection vehicle from turning around to complete the shooting, thereby improving the shooting efficiency.

[0050] In this embodiment, in addition to collecting image information, the position information of the inspection vehicle also needs to be collected. After the inspection vehicle arrives at the target berth, the accuracy of the target berth is determined through the position information of the inspection vehicle. Therefore, the inspection device of this embodiment further includes a positioning module 30, and the positioning module 30 is used to collect the position information of the inspection vehicle and the position information.

[0051] Preferably, in this embodiment, positioning is performed through the Global Navigation Satellite System (GNSS). The positioning module 30 includes an RTK module 31 and a GNSS receiver 32. The RTK module 31 is connected to the main control module 40, and the GNSS receiver 32 is connected to the RTK module 31. The RTK module 31, namely the Real Time Kinematic module, is a real-time differential GPS (RTDGPS) technology module based on carrier phase observation. It uses the principle of differential GPS (DGPS) to achieve centimeter-level positioning accuracy through real-time data communication between the reference station and the rover station. The working principle of the GNSS receiver 32 is based on the method of measuring pseudorange and carrier phase. By receiving and processing satellite signals, it calculates the distance and angle information between the receiver and the satellite, and then determines the position and speed of the receiver. In this embodiment, through the connected GNSS receiver 32 and RTK module 31, GPS positioning of the inspection vehicle is achieved. This embodiment can also perform GPS positioning through the inertial navigation module 33. The full name of the inertial navigation module 33 is the inertial navigation module, which is a module adopting GNSS / INS (Inertial Navigation System) integrated navigation and positioning technology. Without the need for an odometer or speed signal access, it provides high-precision positioning information for the device through high-precision six-axis inertial devices. The inertial navigation module 33 is particularly suitable for weak signal environments such as underground garages.

[0052] In some embodiments, the power supply unit for powering the inspection device may include a buck module 70 and an electric vehicle battery 71. The buck module 70 reduces the voltage provided by the electric vehicle battery 71 to the voltage required by the main control module 40. In other embodiments, as Figure 3 shown, the power supply unit for powering the inspection device may further include a buck module 70, a power module 72, a battery 73, and an electric vehicle battery 71. The buck module 70 is respectively connected to the electric vehicle battery 71 and the main control module 40. That is, two power supply modules, namely the battery 73 and the electric vehicle battery 71, are adopted, and the power module 72 can be used to switch between these two power supply modes.

[0053] The inspection device of this embodiment further includes a voice broadcast module 90, and the voice broadcast module 90 is connected to the main control module 40. The voice broadcast module can be used to broadcast information such as the inspection route to the inspector.

[0054] Preferably, the communication module includes a 4G communication module 81 and a WIFI communication module 83. The 4G communication module and the WIFI communication module are connected in parallel to the main control module 40. In addition, a SIM card 82 is installed on the 4G communication module 81 to achieve wireless communication with the mobile network.

[0055] Current inspection vehicle technologies mostly adopt the method of fixed-route and fixed-frequency inspections, which have problems such as waste of manpower and low utilization rate of inspection vehicles. Based on this, in some possible embodiments, within the scope of the same inspection area, there are generally multiple on-vehicle parking inspection devices. The multiple on-vehicle parking inspection devices are communicatively connected through a communication module (for example, a 4G communication module 81) to receive the position information of other on-vehicle parking inspection devices. Among them, the positioning module 30 provides the position information of the inspection vehicle, and the geomagnetic sensor at the target berth can provide the vehicle entry signal and the position information of the target berth. In this way, each on-vehicle parking inspection device can determine the distance between its own position and the target berth. In response to the shortest distance to the target berth, the on-vehicle parking inspection device corresponding to the shortest distance will prompt the inspector driving the on-vehicle parking inspection device to conduct an inspection. The prompting method can be through a voice broadcast module. In specific implementation, multiple parking inspection devices within the scope of the same inspection area are scheduled and bound through the main control module to form a regional fleet. When a vehicle enters the target berth within this area, each on-vehicle parking inspection device calculates the distance between its current position and the target berth based on its own current position, and also calculates the distance between other on-vehicle parking inspection devices in the regional fleet and the target berth based on other on-vehicle parking inspection devices. It judges whether the on-vehicle parking inspection device itself is the vehicle with the shortest distance within the regional fleet, that is, the distance to the target berth is the shortest distance. If the judgment is yes, the optimal inspection route is calculated through existing algorithms, such as the Dijkstra algorithm, and the inspector is notified of the optimal route through the voice broadcast block for inspection; if the judgment is no, the inspector is notified to wait in place for the next order. The inspection vehicle and the inspector do not need to conduct inspections at fixed frequencies and do not need to follow fixed routes, thereby reducing useless inspection time, reducing manpower, increasing the number of berths covered by a single vehicle, improving the utilization rate of the inspection vehicle, reducing the procurement investment of the inspection vehicle, and also being able to expand the inspection area through multi-vehicle linkage. In some possible embodiments, the main control module can automatically plan the inspection route according to the real-time position changes of the on-vehicle parking inspection device and the position of the target berth, which is convenient for dispatching the inspection vehicle with the optimal route for inspection, so as to be able to dynamically adjust the inspection route and automatically navigate and plan the inspection route, that is, to achieve efficient and flexible inspection operations.

[0056] In some possible embodiments, the on-vehicle parking inspection device further includes a touch screen, and a berth map can also be pre-installed in each on-vehicle parking inspection device. Combining the berth map and the positioning module 30, the driving route and the real-time position of the inspection vehicle are displayed on the touch screen. The driving route is used to represent the driving route between the on-vehicle parking inspection device and the target berth.

[0057] After the inspector arrives at the target berth, the image acquisition component can Figure 2Image acquisition is performed as shown, and the main control module 40 can determine the parking bill of the vehicle based on the acquired image. When the vehicle exits the target berth, the geomagnetic sensor in the target berth senses the vehicle's departure, and the geomagnetic sensor sends a vehicle departure signal to the main control module. The geomagnetic reception status module receives the vehicle departure signal, and the main control module sends the parking fee information to the vehicle owner according to the vehicle departure signal.

[0058] The main control module 40 of this embodiment is used to receive the vehicle entry signal sent by the geomagnetic reception status module 10, receive the position information sent by the positioning module 30, and receive the vehicle image information and parking berth image information sent by multiple image acquisition components respectively. Moreover, the voice information to be broadcast is also sent to the voice broadcast module.

[0059] The storage module 50 is used to receive and store the vehicle entry signal, vehicle image information, and parking berth image information sent by the main control module 40. Preferably, the storage module 50 includes a connected SATA interface 51 module and an SSD solid-state drive 52, where the SATA interface 51 module is connected to the main control module 40. SATA (Serial Advanced Technology Attachment) is a computer bus used for data transmission between the main control module 40 and the SSD solid-state drive 52.

[0060] Refer to Figure 5 , a patrol system provided in this embodiment includes a service platform terminal 300 and multiple on-vehicle parking patrol devices 100 respectively connected to the service platform terminal 300. As Figure 3 shown, the patrol device 100 further includes a connected 4G communication module 81 and a SIM card 82, and the 4G communication module 81 and the SIM card 82 are connected to the main control module. Therefore, wireless communication between the patrol vehicle device 100 and the service platform terminal 300 can be realized through the 4G communication module 81 and the SIM card 82 as shown in Figure 3 shown. By setting multiple patrol devices 100, patrol of multiple parking sections in an area can be realized.

[0061] In addition, in some possible embodiments, when the geomagnetic sensor in the target berth senses that a vehicle has entered, the vehicle entry signal can be first uploaded to the service platform terminal 300 through a pre-installed geomagnetic platform, and the service platform terminal 300 then forwards the vehicle entry signal to the geomagnetic status reception module 10 of each on-vehicle parking patrol device in the area where the target berth is located.

[0062] When the corresponding inspection vehicle arrives at the target berth and uses the on-vehicle parking inspection device to collect image information of the vehicle, the on-vehicle parking inspection device can upload the collected image information and parking bill to the business platform. The business platform terminal 300 stores this information for subsequent management and query. The business platform terminal 300 can also form an entry order and push the entry order to the vehicle owner through the 4G communication module. Similarly, when the vehicle exits the target berth, the geomagnetic sensor can also upload the vehicle exit signal to the business platform terminal 300 through the geomagnetic platform. The business platform terminal 300 determines the parking fee according to the entry order and pushes the parking fee to the vehicle owner through the 4G communication module.

[0063] As is known by common technical knowledge, the present utility model can be implemented by other embodiments that do not depart from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and are not exclusive.
