Description

Technical Field

[0001] This utility model relates to the field of parking monitoring equipment technology, and in particular to a wireless solar-powered high-position camera based on radar detection. Background Technology

[0002] The technical background of roadside parking high-position cameras involves the cross-integration of computer vision, edge computing, Internet of Things (IoT) and intelligent transportation systems, and its development relies on the breakthroughs in artificial intelligence algorithms, sensor hardware and communication technologies in recent years.

[0003] In existing high-position camera implementations on the market, the common approach is to lay network cables and power cables, using high-position cameras to continuously capture video streams and images, and applying artificial intelligence algorithms to continuously detect and identify the monitored berths 24 hours a day.

[0004] Currently, Chinese Patent Publication No. CN214959894U discloses a high-position camera, including an image acquisition unit for monitoring at least one parking space. The image acquisition unit includes two first cameras, which are positioned at a fixed angle. The two first cameras are connected to a first processing unit, and each first camera is fitted with an adjustment ring to adjust its angle and direction. A first protective cover is fitted over the first camera, and a base is provided on top of the first protective cover. A support frame is rotatably connected to the base, and a power supply unit is provided on top of the support frame.

[0005] Although these high-position cameras can simplify the installation process, they typically need to be mounted on 3-6 meter high poles because they monitor multiple parking spaces. If there are streetlights or monitoring poles available, it is relatively convenient. Otherwise, a tall pole needs to be erected, which is more complex and expensive. Currently, most high-position cameras use power cables and network cables, but roadside parking equipment usually needs to be installed on both sides of the road, making the installation of power and network cables complicated and requiring coordination with multiple departments.

[0006] High-position cameras are highly dependent on the environment. Obstruction issues: Trees, billboards, or large vehicles may obstruct the view of parking spaces, leading to missed or false detections. Heavy rain, snow, or smog may also reduce the recognition accuracy, resulting in missed or false detections of vehicles in adverse weather conditions and when obstructed by trees, billboards, or large vehicles, thus affecting the vehicle detection rate. Utility Model Content

[0007] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a wireless solar-powered high-position camera based on radar detection, which can solve the problem that the detection rate is affected by the external environment, resulting in missed detections and false alarms of vehicles.

[0008] To achieve the above and other related objectives, this utility model provides a wireless solar-powered high-position camera based on radar detection, comprising a body, a camera module disposed within the body for capturing images of parking spaces, a radar module linked to the camera module for identifying vehicles via microwave radar, and a solar module disposed on the upper side of the body. The camera module includes multiple cameras disposed within the body and a transparent cover disposed on the end face of the body. The radar module includes a microwave radar disposed outside the body and a connecting plate connecting the microwave radar and the cameras.

[0009] By adopting the above technical solution, an additional radar module is added to the existing camera video detection technology. The dual detection of vehicles is achieved by using a microwave radar sensor and a camera. This effectively improves the detection rate of vehicles in adverse weather conditions and when obstructed by trees, billboards, or large vehicles, thus reducing the problems of missed detections and false alarms. It also greatly reduces the power consumption of the wireless high-position camera. At the same time, the hardware uses wireless solar power to charge the lithium battery, eliminating the trouble of running power cables during construction. Furthermore, the use of a wireless communication module to transmit signals avoids the trouble of running network cables during construction, greatly reducing the complexity of construction.

[0010] In one embodiment of this utility model, two cameras are provided and are arranged opposite to each other on both sides of the body. The body is also provided with a rotating bracket that can support the cameras and drive the cameras to deflect in the horizontal direction. Each camera is provided with a corresponding rotating bracket.

[0011] By adopting the above technical solution and using dual cameras, four parking spaces can be monitored simultaneously. The cameras can capture videos and pictures and work in conjunction with microwave radar. When the radar detects a parking space and the threshold is reached, the microcontroller board will power on the camera and start it up. The camera module will capture the current scene and identify vehicles, license plates, colors, etc. The camera's shooting range can be adjusted by rotating the bracket inside the unit.

[0012] In one embodiment of this utility model, the microwave radar is provided with two cameras, which are respectively set on the lower side of the two cameras through a connecting plate. The lower side of the body has a sliding groove for the displacement of the connecting plate.

[0013] By adopting the above technical solution, the microwave radar can move in conjunction with the camera via the connecting plate, enabling it to use electromagnetic waves to detect targets, and determine whether to activate the camera based on the returned waveform and the set threshold.

[0014] In one embodiment of the present invention, a power module connected to the solar module for energy storage is further provided inside the machine body, and the power module includes a lithium battery disposed inside the machine body.

[0015] By adopting the above technical solution, it can be charged using solar energy or a charger.

[0016] In one embodiment of the present invention, the solar module includes a solar panel disposed on the upper side of the body.

[0017] By adopting the above technical solution, solar energy is converted into electrical energy through the photovoltaic effect, and then the lithium battery of the power module is safely charged through the charging control circuit. The unstable voltage / current output of the solar panel is adjusted to match the charging needs of the lithium battery and prevent overcharging or over-discharging, so as to meet the power consumption of the wireless solar video pile. When charging is complete, the charging of the lithium battery is automatically interrupted.

[0018] In one embodiment of this utility model, a microcontroller module for controlling various modules and performing data processing is also provided in the machine body.

[0019] By adopting the above technical solution, the CPU, memory, peripheral interfaces, etc. are integrated into this module, which is used to control cameras, radar, and data processing.

[0020] As described above, the radar-based wireless solar-powered high-position camera of this invention has the following beneficial effects:

[0021] 1. No need for electricity or grid installation; it uses wireless signal transmission and solar and lithium battery charging and power supply, which simplifies the complexity of construction, reduces coordination between departments, and speeds up the construction progress.

[0022] 2. By using millimeter-wave radar to determine the entry and exit status of vehicles in the corresponding parking spaces, the time required for video detection using high-position cameras is greatly reduced, saving power consumption;

[0023] 3. By using millimeter-wave radar for judgment, false alarms and missed alarms by high-position cameras are avoided when there are trees, billboards or large vehicles blocking the view, or in bad weather conditions;

[0024] 4. The high-position camera uses dual cameras, which can monitor 4 berths simultaneously;

[0025] 5. It can start up quickly, completing the process from power-on to snapshot within a few seconds, greatly reducing camera power consumption;

[0026] 6. Equipped with solar panels and a high-capacity lithium battery, the solar panels can charge the lithium battery at any time, avoiding battery replacement and reducing operational workload;

[0027] 7. Modular hardware design: The overall hardware design can be divided into a power module, a radar detection module, a solar module, a 4G module, and a camera module. Attached Figure Description

[0031] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0032] Please see Figure 1 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0033] Please see Figure 1 This utility model provides a wireless solar-powered high-position camera based on radar detection, including a body, a camera module 3 installed in the body for capturing images of parking spaces, a radar module 4 linked to the camera module 3 for identifying vehicles via microwave radar, and a solar module 1 installed on the upper side of the body.

[0034] The camera module 3 includes multiple cameras installed inside the body and a transparent cover 7 installed on the end face of the body. In this embodiment, there are two cameras installed and they are positioned opposite each other on both sides of the body. The body also has a rotating bracket 8 that can support the cameras and drive them to rotate in the horizontal direction. Each camera is provided with a corresponding rotating bracket 8. In this embodiment, the camera uses a 400W pixel image sensor.

[0035] The radar module 4 includes a microwave radar installed on the outside of the body and a connecting plate 9 connecting the microwave radar and the camera. The microwave radar is equipped with two cameras, which are respectively installed on the lower side of the two cameras through the connecting plate 9. The lower side of the body has a sliding groove for the displacement of the connecting plate 9. When the camera rotates under the drive of the rotating bracket 8, it can drive the microwave radar on its lower side to move through the connecting plate 9, so that the radar detection is more compatible with the camera.

[0036] The system uses microwave radar to detect targets using electromagnetic waves, and determines whether to activate the camera based on the returned waveform and the set threshold.

[0037] The device also includes a wireless communication module 5 for data transmission. In this embodiment, the wireless communication module 5 is a 4G module that uses wireless 4G signal transmission to transmit data to the background.

[0038] The device also includes a power module 2 connected to the solar module 1 for energy storage. The power module 2 includes a lithium battery installed inside the device.

[0039] The solar module 1 includes a solar panel located on the upper side of the body. The solar panel receives solar energy and converts the received solar energy into charging power for the rechargeable lithium battery.

[0040] The camera also includes a microcontroller module 6 for controlling various modules and processing data. In this example, the microcontroller module 6 uses a low-power embedded processor, XBurst-1core 1.5GHz, which can start up quickly and complete the process from power-on to snapshot within a few seconds, greatly reducing the camera's power consumption.

[0041] When in use, solar module 1 receives solar energy and converts it into electrical energy through the photovoltaic effect. Then, the charging control circuit safely charges the lithium battery of power module 2, adjusts the unstable voltage / current output of the solar panel to match the charging needs of the lithium battery, and prevents overcharging or over-discharging to meet the power consumption of the wireless solar video station. When charging is complete, the charging of the lithium battery is automatically interrupted.

[0042] 2. To avoid missed or false detections in video detection due to obstruction and inclement weather, a low-power radar sensor module is used. After the radar module 4 is powered on, it starts detection and uses the change in the waveform of the energy value of the detected object to determine whether there is a vehicle in the parking space and whether the vehicle is in the process of entering or leaving. When the set vehicle detection threshold is reached, the microcontroller module 6 is notified to power on the camera module 3 to start working. If the threshold is less than the set vehicle detection threshold, it is automatically ignored and no processing is performed.

[0043] 3. After the camera module 3 is powered on, it starts working and can acquire video stream information of the current parking space. It can perform vehicle recognition, license plate recognition, etc. When a vehicle or license plate is recognized, it takes a picture.

[0044] 4. After the camera module 3 completes the recognition and photo-taking functions, the microcontroller module 6 processes the data and uses the wireless communication module 5 to transmit the evidence chain, including images and video streams containing time, parking space status, vehicles and license plates, to the smart parking platform. The smart platform can perform secondary recognition to improve the accuracy of vehicles and license plates.

[0045] 5. After the transmission is complete, camera module 3 automatically powers down and enters sleep mode.

[0046] In summary, this utility model, based on existing camera video detection technology, additionally sets up a radar module 4. By using a microwave radar sensor and a camera to achieve dual detection of vehicles, it can effectively improve the problem of missed detection and false alarms of vehicles in adverse weather conditions and when obstructed by trees, billboards, or large vehicles, thereby increasing the vehicle detection rate. It also greatly reduces the power consumption of the wireless high-position camera. At the same time, the hardware device uses wireless solar power to charge the lithium battery, eliminating the trouble of running power cables during construction. In addition, it uses a wireless communication module 5 to transmit signals, avoiding the trouble of running network cables during construction, and greatly reducing the complexity of construction.

[0047] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
