Description

Technical Field

[0001] This utility model relates to the technical field of parking space monitoring, and more specifically, to a dual-mode two-wheeled vehicle detection device based on radar and infrared. Background Technology

[0002] The motorcycle parking area features individually marked parking spaces for each motorcycle, rather than a designated parking area. These one-motorcycle-per-space designations help to organize vehicles more neatly and keep streets cleaner.

[0003] However, when motorcycle parking areas are set up with individually marked parking spaces for each motorcycle, once most spaces are occupied, it's difficult to spot available spaces from the outside. Motorcyclists must then ride through the area to find a spot. When all spaces are taken, riders often spend a significant amount of time searching without success. This inability to quickly find available parking spaces leads to parking difficulties and diminishes the overall riding experience for motorcyclists. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where, when most parking spaces in a parking area are occupied, it is difficult for car owners to find out whether there are any vacant parking spaces by observing from the outside of the parking area, causing them to spend a lot of time searching for parking spaces. This invention provides a dual-mode two-wheeled vehicle detection device based on radar and infrared. This dual-mode two-wheeled vehicle detection device based on radar and infrared can monitor the usage of parking spaces and provide feedback on the usage of parking spaces.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A dual-mode two-wheeled vehicle detection device based on radar and infrared is provided, including a housing and a parking space monitoring module, a control module, a signal transmission module and a power supply module fixedly installed in the housing; The bottom of the housing can be fixedly installed at one end of the parking space in the direction of vehicle entry; The parking space monitoring module can monitor whether a parking space is occupied by a two-wheeled vehicle; The signal transmission module can transmit parking space occupancy information to the receiving terminal; The control module is connected to the parking space monitoring module and the signal transmission module, and the control module can control the operation of the parking space monitoring module and the signal transmission module; The power module is connected to the parking space monitoring module, the control module, and the signal transmission module to supply power to the parking space monitoring module, the control module, and the signal transmission module.

[0006] The signal transmission module includes a UNB communication circuit and a Bluetooth communication chip. When the notification module interacts with the local area network via the UNB communication circuit, it ensures the stability and efficiency of data transmission, meeting the real-time requirements of parking space monitoring systems. The Bluetooth communication chip facilitates the setting and adjustment of various parameters, improving debugging efficiency.

[0007] The control module utilizes the N32L406 low-power, high-performance 32-bit microcontroller from NationalTech. This chip integrates abundant peripheral resources, including timers, interrupt controllers, and various communication interfaces. The microcontroller is primarily responsible for collecting data from the parking space monitoring module and determining the occupancy status of parking spaces. Furthermore, it transmits the parking space status information to the gateway via a UNB communication circuit. After the gateway forwards the information to the base station, car owners and other users can obtain real-time parking space occupancy information through mobile apps or other devices.

[0008] This utility model discloses a dual-mode two-wheeled vehicle detection device based on radar and infrared. In use, the bottom of the housing is fixed directly in front of the parking space, with one device fixedly installed in front of each parking space. The parking space monitoring module can then detect whether a two-wheeled vehicle is parked in that space and send this information to the control module. The control module receives and processes the information. If a two-wheeled vehicle is parked in the space, the control module outputs parking space occupancy information; if no two-wheeled vehicle is parked in the space, the control module outputs parking space vacancy information. The control module sends the parking space information to the signal transmission module, which then transmits the parking space information outwards. Users can then view the occupancy status of all parking spaces in this parking area through an app or other terminal, eliminating the need to walk back and forth within the parking area to find an vacant space.

[0009] This utility model discloses a dual-mode two-wheeled vehicle detection device based on radar and infrared, which can monitor the occupancy of two-wheeled vehicle parking spaces in real time. This allows vehicle owners to know in a timely manner whether there are any vacant parking spaces and which spaces are vacant, making it easier for them to find vacant parking spaces and park, reducing the time spent searching for parking spaces and optimizing the parking experience for vehicle owners when riding bicycles.

[0010] Furthermore, the parking space monitoring module includes a millimeter-wave radar and an infrared laser rangefinder. Both the millimeter-wave radar and the infrared laser rangefinder are fixedly installed within the housing cavity. The millimeter-wave radar detects whether a two-wheeled vehicle is parked in the parking space, and the infrared laser rangefinder measures the distance between the device and the front wheel of the vehicle. Both the millimeter-wave radar and the infrared laser rangefinder are connected to the control module. The parking space monitoring module uses both infrared laser rangefinder and millimeter-wave radar detection to comprehensively determine whether a vehicle is parked in the parking space, making the control module's judgment on parking space occupancy more accurate. The millimeter-wave radar can be an SG24TR12 chip, which operates in the 24GHz frequency band. In terms of design, the radar antenna's 3dB beamwidth horizontal range is controlled between -27° and 27°, employing FMCW (Frequency Modulated Continuous Wave) technology to achieve high resolution and stability for target monitoring. The infrared laser rangefinder utilizes the VL53L1CXV0FY / 1 laser ToF sensor, operating in the 940nm invisible light band with a 27° field of view. It features high integration, a maximum ranging distance of 2m, and a measurement resolution of 1mm. It is minimally affected by target color and material, enabling precise detection of objects and effectively improving monitoring accuracy. Furthermore, the infrared laser rangefinder can also measure the distance from the vehicle's front wheels to the device.

[0011] Furthermore, the distance between the infrared laser rangefinder and the bottom surface of the housing is 30cm-40cm, and the millimeter-wave radar is closer to the bottom of the housing than the infrared laser rangefinder. The vertical arrangement of the millimeter-wave radar and infrared laser rangefinder further reduces the width of the device. The 30cm-40cm distance between the infrared laser rangefinder and the bottom surface of the housing allows for better detection of the position of the vehicle's front wheels, i.e., the distance between the closest point of the vehicle to the device and the device itself, enabling an external alarm to be triggered via the control module before a collision occurs. The millimeter-wave radar is positioned below the infrared laser rangefinder, further reducing the overall height of the device, which can then be maintained between 40cm-50cm. This allows for low-level monitoring of parking spaces, further reducing the device's cost. Simultaneously, the housing can be made of high-strength materials, giving it excellent impact resistance and providing comprehensive safety protection for the equipment.

[0012] Furthermore, the housing is also provided with a shielding part protruding from the outer surface of the housing, and the shielding part is located above the infrared laser rangefinder. The shielding part can prevent rainwater from dripping onto the infrared laser rangefinder when it rains, thus preventing rainwater from affecting the accuracy of the infrared laser rangefinder's measurement results and further improving the accuracy of the parking space monitoring module.

[0013] Furthermore, the detection end of the millimeter-wave radar is tilted on the housing, with the top of the detection end tilted towards the inner cavity of the housing at an angle of 5°-10°. This upward tilt of the millimeter-wave radar makes it easier to identify the main body of the vehicle.

[0014] Furthermore, the system also includes indicator lights. Both the control module and the power module are connected to the indicator lights, which are mounted on the side wall of the housing near its top. In low-light conditions, such as at night, the indicator lights can use different colors to show the occupancy status of parking spaces. For example, when a vehicle is parked in a space, the indicator light is red; when no vehicle is parked in a space, the indicator light is green. Drivers can quickly find unoccupied parking spaces in low-light conditions using the indicator lights. Additionally, the flashing of the indicator lights can be used to monitor the progress of program adjustments.

[0015] Furthermore, it also includes a lighting unit, which is fixedly installed in the housing. The lighting unit is closer to the bottom surface of the housing than the millimeter-wave radar, and is connected to the control module and the power module. The lighting unit, installed at the bottom of the housing, illuminates the parking space in low-light conditions such as at night, preventing drivers from scratching vehicles in adjacent spaces while parking. It also reminds drivers of the device's installation location, preventing collisions between vehicles and the device during parking.

[0016] Furthermore, the power module includes a battery compartment fixedly installed inside the housing cavity and a battery detachably connected to the battery compartment. The housing also has a detachable back cover that can be fastened to the battery compartment. After opening the back cover on the housing, the battery in the battery compartment can be replaced, and the device can be continuously powered by replacing the battery, eliminating the need for additional power supply lines and effectively improving the convenience of using the device.

[0017] Furthermore, it also includes a base that can be fixed to the parking space floor. The housing is rotatably connected to the base, and a rotating part is fixedly installed inside the housing. The rotating part is connected to the control module and the power module, and the drive end of the rotating part is fixedly connected to the base. The rotation angle of the housing on the base is ±180°. When the control module cannot determine whether there is a vehicle parked in the parking space through the signals of the infrared laser rangefinder and millimeter-wave radar, the control module can drive the rotating part to work. The rotating part drives the housing to rotate on the base, thereby changing the recognition angle of the millimeter-wave radar and infrared laser rangefinder, further improving the recognition accuracy. At this time, the deflection angle of the rotating part is controlled within 10°. This is to avoid the problem that the parking space monitoring module will make incorrect judgments after recognizing a vehicle parked in the adjacent parking space if the deflection angle of the rotating part is too large. When the device is installed between two parking spaces with opposite entry directions, the rotation angle of the rotating part is ±180°. At this time, the device can detect whether the two parking spaces are occupied by rotating, further improving the utilization rate of the device and reducing the installation cost of the device.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a dual-mode two-wheeled vehicle detection device based on radar and infrared, which can monitor the occupancy of two-wheeled vehicle parking spaces in real time. This allows vehicle owners to know in a timely manner whether there are any vacant parking spaces and which spaces are vacant, making it easier for them to find vacant parking spaces and park, reducing the time spent searching for parking spaces and optimizing the parking experience for vehicle owners when riding bicycles.

[0023] Example 1 This embodiment is a first embodiment of a dual-mode two-wheeled vehicle detection device based on radar and infrared, such as... Figures 1-2 As shown, it includes a housing 1 and a parking space monitoring module 2, a control module 3, a signal transmission module 4, and a power supply module 5, which are fixedly installed on the housing 1; The bottom of housing 1 can be fixedly installed at one end of the parking space in the direction of vehicle entry; Parking monitoring module 2 can monitor whether a parking space is occupied by a two-wheeled vehicle; Signal transmission module 4 can transmit parking space occupancy information to the outside. The control module 3 is connected to the parking space monitoring module 2 and the signal transmission module 4. The control module 3 can control the operation of the parking space monitoring module 2 and the signal transmission module 4. The power supply module 5 is connected to the parking space monitoring module 2, the control module 3 and the signal transmission module 4 to supply power to the parking space monitoring module 2, the control module 3 and the signal transmission module 4.

[0024] Specifically, signal transmission module 4 includes a UNB communication circuit and a Bluetooth communication chip. The UNB communication circuit sends parking space status information to the gateway, the gateway sends the information to the base station, and the base station sends the signal to the receiving terminal. Control module 3 uses an N32L40 632-bit microcontroller.

[0025] Specifically, this also includes parking space display screens installed at the entrance of the parking area. These screens can receive signals from signal transmission module 4 and display the occupancy status of all parking spaces. More specifically, the parking space display screens can receive signals from the base station and display the occupancy status of all parking spaces on the screen. For example, when the monitoring device for a parking space sends an occupancy signal, the screen will show that the space is occupied.

[0026] Specifically, the parking space monitoring module 2 includes a millimeter-wave radar 201 and an infrared laser rangefinder 202. Both the millimeter-wave radar 201 and the infrared laser rangefinder 202 are fixedly installed in the inner cavity of the housing 1. The millimeter-wave radar 201 is used to detect whether there are two-wheeled vehicles parked in the parking space, and the infrared laser rangefinder 202 is used to measure the distance between the device and the front wheel of the vehicle. Both the millimeter-wave radar 201 and the infrared laser rangefinder 202 are connected to the control module 3.

[0027] Specifically, the bottom of the housing 1 is fixed to the ground directly in front of the parking space, with a distance of 20cm-30cm between the housing 1 and the parking space. The front of the vehicle is the middle position of the parking space, which is the end where the front of the vehicle is facing after entering the parking space.

[0028] The working principle or process of this embodiment is as follows: A dual-mode two-wheeled vehicle detection device based on radar and infrared uses an infrared laser rangefinder 202 and a millimeter-wave radar 201 in the parking space monitoring module 2 to monitor whether there are vehicles within a distance of 1m-1.5m in front of the device, and sends the detection results to the control module 3. The control module 3 receives the information and processes it. If a two-wheeled vehicle is parked in the parking space, the control module 3 outputs parking space occupancy information; if no two-wheeled vehicle is parked in the parking space, the control module 3 outputs parking space vacancy information. The control module 3 sends the parking space information to the signal transmission module 4. After the signal transmission module 4 transmits the parking space information outward, users can view the occupancy status of all parking spaces in this parking area through an app or a parking space display screen in the parking area.

[0029] The beneficial effects of this embodiment are as follows: This embodiment of a dual-mode two-wheeled vehicle detection device based on radar and infrared can monitor the occupancy of parking spaces for motorcycles or electric vehicles in real time, making it easier for vehicle owners to know whether parking spaces are available and which spaces are vacant. This allows vehicle owners to find vacant parking spaces in a timely manner and park, reducing the time spent searching for parking spaces and optimizing the parking experience for vehicle owners when traveling by bicycle.

[0030] The parking space monitoring module 2 uses both infrared laser rangefinder 202 and millimeter-wave radar 201 to comprehensively determine whether a vehicle is parked in the parking space, making the judgment result of the control module 3 more accurate when judging the occupancy of the parking space.

[0031] Example 2 This embodiment is a second embodiment of a dual-mode two-wheeled vehicle detection device based on radar and infrared, such as... Figures 1-4 As shown, this embodiment further defines the structure of the device based on embodiment one.

[0032] Specifically, the distance between the infrared laser rangefinder 202 and the bottom surface of the housing 1 is 30cm-40cm, and the millimeter-wave radar 201 is closer to the bottom of the housing 1 than the infrared laser rangefinder 202.

[0033] Specifically, the housing 1 is also provided with a shielding part 101 protruding from the outer surface of the housing 1, and the shielding part 101 is located above the infrared laser rangefinder 202.

[0034] Specifically, the detection end of the millimeter-wave radar 201 is tilted on the housing 1, and the top of the detection end of the millimeter-wave radar 201 is tilted towards the inner cavity of the housing 1 at an angle of 5°-10°.

[0035] Specifically, the power module 5 includes a battery compartment fixedly installed in the inner cavity of the housing 1 and a battery detachably connected to the battery compartment. The housing 1 is also provided with a detachable back cover 102, which can be fastened to the battery compartment.

[0036] Specifically, it also includes indicator light 6 and buzzer. Control module 3 and power module 5 are both connected to indicator light 6 and buzzer. Indicator light 6 is installed on the side wall of housing 1 near its top end, and buzzer is fixedly installed in the inner cavity of housing 1.

[0037] Specifically, it also includes an illumination unit 7, which is fixedly installed on the housing 1. The illumination unit 7 is closer to the bottom surface of the housing 1 than the millimeter-wave radar 201. The illumination unit 7 is connected to the control module 3 and the power module 5. The illumination unit 7 is an LED light panel.

[0038] The working principle or process of this embodiment is as follows: When a vehicle owner parks their vehicle, if the control module 3 detects that the infrared laser rangefinder 202 has detected that the distance to the vehicle's front wheels has reached a dangerous range, the control module 3 sends a working signal to indicator light 6 and buzzer. Indicator light 6 flashes, and the buzzer sounds an alarm, reminding the vehicle owner that the vehicle's front wheels are about to collide with a dual-mode two-wheeled vehicle detection device based on radar and infrared. Simultaneously, indicator light 6 remains constantly lit, displaying either red or green. A constantly lit red indicator light 6 indicates that the parking space is occupied; a constantly lit green indicator light 6 indicates that the parking space is vacant.

[0039] When the battery in the battery compartment is depleted, the back cover 102 on the housing 1 can be opened to replace the battery.

[0040] The beneficial effects of this embodiment are as follows: The distance between the infrared laser rangefinder 202 and the bottom surface of the housing 1 is 30cm-40cm, which allows for better detection of the position of the foremost point of the vehicle's front wheel, i.e., the distance between the closest point of the vehicle to the device and the device. Before a collision occurs between the wheel and the device, an alarm signal is sent to the alarm module via the control module 3, and the alarm module then sends an alarm signal to the outside world. The millimeter-wave radar 201 is positioned below the infrared laser rangefinder 202, further reducing the overall height of the device and its cost.

[0041] The shielding part 101 prevents rainwater from dripping onto the infrared laser rangefinder 202 during rain, thus avoiding the impact of rainwater on the accuracy of the measurement results and further improving the accuracy of the parking space monitoring module 2. The millimeter-wave radar 201 is tilted upwards, making it easier to identify the main body of the vehicle.

[0042] The batteries in the battery compartment are replaceable, allowing the device to be continuously powered without the need for additional power lines, thus significantly improving the ease of use.

[0043] In low-light conditions such as at night, the indicator lights can quickly help drivers find available parking spaces by displaying different colors, reducing the time drivers spend searching for parking spaces.

[0044] The beneficial effects of this embodiment are as follows: The lighting unit 7 can illuminate the parking space in low-light conditions such as at night, preventing car owners from scratching vehicles in adjacent parking spaces while parking. It can also remind car owners of the device's installation location, preventing vehicles from colliding with the device while parking.

[0045] Example 3 This embodiment is a third embodiment of a dual-mode two-wheeled vehicle detection device based on radar and infrared, such as... Figure 5 and Figure 6As shown, this embodiment further defines the structure of the shell 1 based on embodiment 2.

[0046] Specifically, it also includes a base 12 that can be fixed to the ground of the parking space. The housing 1 is rotatably connected to the base 12. A rotating part 8 is fixedly installed in the inner cavity of the housing 1. The rotating part 8 is connected to the control module 3 and the power module 5. The drive end of the rotating part 8 is fixedly connected to the base 12. The rotating part 8 is a servo motor.

[0047] Specifically, the rotation angle of the housing 1 on the base 12 is ±10°.

[0048] The working principle or process of this embodiment is as follows: When the control module 3 receives a signal from the signal transmission module 4 and cannot determine whether the parking space is occupied based on the signal, the control module 3 drives the rotating part 8 to work. The rotating part 8 rotates and causes the housing 1 to move slightly on the base 12. After the housing 1 rotates, the signal transmission module 4 re-detects the parking space and sends the detection signal to the control module 3. The control module 3 then combines the signals from the second detection to make a judgment again.

[0049] The beneficial effects of this embodiment are as follows: The housing 1 can rotate on the base 12. When the control module 3 cannot determine whether there is a vehicle parked in the parking space based on the signals from the infrared laser rangefinder 202 and the millimeter-wave radar 201, the rotating part 8 drives the housing 1 to rotate on the base 12, changing the recognition angle of the millimeter-wave radar 201 and the infrared laser rangefinder 202, thereby further improving the accuracy of recognition. The deflection angle of the rotating part 8 is controlled within 10°. This is to avoid the problem that if the deflection angle of the rotating part 8 is too large, the parking space monitoring module 2 will make an incorrect judgment after recognizing a vehicle parked in the adjacent parking space.

[0050] Example 4 This embodiment is the fourth embodiment of a dual-mode two-wheeled vehicle detection device based on radar and infrared. The difference between this embodiment and embodiment three is that the applicable occasions of the device and the rotation angle of the housing on the base are different.

[0051] Specifically, such as Figure 7 As shown, when the device is installed in two parking spaces with coincident axes but opposite directions of vehicle entry, the rotation angle of the rotating part is ±180°.

[0052] The working principle or process of this embodiment: The control module 3 controls the servo motor to rotate periodically. The servo motor drives the housing 1 to rotate 180° on the base 12 each time, so that the housing 1 periodically monitors the occupancy of two parking spaces in relative positions, and promptly detects parking space occupancy and issues an early warning.

[0053] The beneficial effects of this embodiment: The device can monitor the occupancy of two parking spaces, further improving the utilization rate of the device, reducing the number of devices to be installed, and lowering the cost of parking space monitoring.

[0054] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
