Description

Technical Field

[0001] This utility model relates to the field of parking management equipment technology, specifically to an infrared laser sensing video pile structure. Background Technology

[0002] Video parking barriers are intelligent parking devices that use cameras to capture real-time images of parked vehicles, recording information such as license plates and parking times. Their function is to accurately identify vehicles, enabling unattended payment, improving parking lot management efficiency, and reducing labor costs. The principle involves using computer vision technology to analyze images, identify license plate numbers, and combine this with a timing system to calculate parking fees. For example, patent document CN207571886U discloses a public charging station parking space management system that uses one video barrier to monitor and capture images of each parking space. The timing of the video barrier recording license plates and parking times is highly dependent on the time a vehicle enters / leaves the parking space, which is uncertain. Therefore, the video barrier needs to capture images of the parking space continuously, using the captured video frames for image recognition to determine if a vehicle is in the parking space and then record the relevant information. This long-term monitoring and detection method results in high power consumption and a large amount of information processing for the video barrier.

[0003] Some parking spaces use a combination of geomagnetic sensors and video surveillance cameras. Geomagnetic sensors are used to identify vehicles in the parking space, but their installation and maintenance are costly and usually require significant modifications to the parking space surface. Other parking spaces use infrared beam blocking to detect vehicles, typically employing a single infrared beam. However, parking spaces are frequently used not only by vehicles entering and exiting but also by pedestrians, leading to frequent false alarms and a high misjudgment rate. Summary of the Invention

[0004] To address the problems in related technologies, this utility model proposes an infrared laser sensing video stake structure, which can effectively reduce the monitoring power consumption of the video stake and reduce the misjudgment rate of vehicle identification in parking spaces.

[0005] This utility model is implemented as follows:

[0006] An infrared laser sensing video stake structure is applied to a parking space; it includes two vertical poles; the two vertical poles are respectively located on the left rear side and right rear side of the parking space; one of the vertical poles is equipped with a camera unit for capturing an image of the parking space; each of the two vertical poles is also equipped with an infrared laser recognition unit; the infrared laser recognition unit is electrically connected to the camera unit;

[0007] One of the infrared laser recognition units corresponds to one infrared laser beam. During operation, one end of the infrared laser beam extends to the infrared laser recognition unit, and the other end extends to the front surface of the parking space. The projections of the two infrared laser beams on the ground form a shape similar to an "X".

[0008] The parking space is a "non" - shaped parking space or a "san" - shaped parking space. The front and rear sides of the parking space face the same direction or the opposite direction as the vehicle orientation after parking.

[0009] The infrared laser recognition unit can be used to determine whether the two infrared laser beams are blocked. When in use, when the two infrared laser recognition units simultaneously switch from the state of receiving the infrared laser beam to the blocked state, or simultaneously switch from the blocked state to the receiving state, it indicates the timing when the vehicle enters or exits the parking space, that is, the recording timing of the camera unit. Therefore, the camera unit does not need to collect and monitor the parking space throughout the entire time period; the power consumption is greatly reduced; and when the two laser beams act simultaneously (i.e., are blocked or received), it can greatly reduce misjudgments caused by other factors such as pedestrians passing by.

[0010] Preferably, it further includes two infrared laser emission units, which are respectively located at the left front side and the left rear side of the parking space. Among them, the infrared laser emission unit located at the left front side emits an infrared laser beam towards the infrared laser recognition unit located at the right rear side; the infrared laser emission unit located at the right front side emits an infrared laser beam towards the infrared laser recognition unit located at the left rear side.

[0011] The working principle is as follows:

[0012] When both infrared laser recognition units receive the infrared laser beam, it indicates that there is no vehicle in the parking space, which is regarded as the receiving state; when both infrared laser recognition units do not receive the infrared laser beam, it indicates that there is a vehicle in the parking space and the infrared laser beam is blocked by the vehicle, which is regarded as the blocked state.

[0013] Therefore, when the state of the infrared laser recognition unit changes from receiving simultaneously to being blocked simultaneously, it is regarded as the vehicle entering the parking space; when it changes from being blocked simultaneously to receiving simultaneously, it is regarded as the vehicle leaving the parking space.

[0014] Preferably, the infrared laser recognition unit is a self - reflecting infrared ranging sensor, including a transmitting end and a receiving end. The transmitting end is used to emit an infrared laser beam, and the receiving end is used to receive the infrared laser beam.

[0015] The working principle is as follows:

[0016] When there is no vehicle in the parking space, the infrared laser beam emitted by the transmitting end shoots towards the ground and is reflected in other directions, which is regarded as the blocked state; when there is a vehicle in the parking space, the infrared laser beam emitted by the transmitting end shoots to the rear surface of the vehicle and is reflected back (or approximately back) along the original path towards the receiving end, which is regarded as the receiving state.

[0017] Therefore, when the state of the infrared laser recognition unit changes from simultaneous reception to simultaneous occlusion, it is considered that the vehicle has left the parking space; when it changes from simultaneous occlusion to simultaneous reception, it is considered that the vehicle has entered the parking space.

[0018] Here, "obstruction" does not mean obstruction in its original sense; it is merely a name used to refer to the state of the previous technical solution, but the judgment logic is reversed.

[0019] As a further optimization of the above scheme, the two infrared laser recognition units on a vertical pole are respectively the first recognition unit and the second recognition unit;

[0020] When there are multiple consecutive parking spaces, on the same vertical pole, the first identification unit corresponds to one parking space, and the second identification unit corresponds to an adjacent parking space; the camera unit, the first identification unit on one vertical pole, and the second identification unit on the adjacent vertical pole are electrically connected.

[0021] That is, adjacent parking spaces share a single vertical pole.

[0022] As a further optimization of the above scheme, the width of the parking space is denoted as L; the distance between the two vertical poles is L; and the distance between the two infrared laser beams extending to the two ends of the front surface of the parking space is 1 / 2L to L.

[0023] The two infrared laser beams are projected onto the surface of the parking space in an X-shaped pattern. The projection shape has an intersection point. The smaller the distance between them and the closer the intersection point is to the front of the parking space, the sooner the timing of the vehicle entering the parking space can be confirmed.

[0024] As a further optimization of the above solution, the two infrared laser recognition units on the two vertical poles, corresponding to the same parking space, are installed at different heights.

[0025] The two infrared laser recognition units are misaligned at different heights, and the corresponding infrared laser beams are also misaligned to avoid mutual interference and affecting recognition.

[0026] As a further optimization of the above solution, the upper side of the vertical pole has two first inclined surfaces, each of which faces obliquely toward one of the parking spaces; each of the two first inclined surfaces is equipped with an infrared laser recognition unit, and one of the first inclined surfaces is equipped with the camera unit.

[0027] As a further optimization of the above scheme, the camera unit is located above the infrared laser recognition unit; a first mask and a second mask are provided on the surface of one of the first inclined surfaces; the first mask is located above the camera unit; and the second mask is located above one of the infrared laser recognition units.

[0028] The first shield is used to protect the camera unit from wind, rain, and light, reducing the impact of the external environment on the quality of image acquisition; the second shield is used to reduce the interference of the infrared laser unit directed at the infrared laser recognition unit on the camera unit.

[0029] As a further optimization of the above scheme, the infrared laser emitting unit is also provided with two second inclined surfaces; the second inclined surfaces face obliquely upward; one of the second inclined surfaces is provided with an infrared laser emitting part, and the other second inclined surface is provided with a light emitting part; the infrared laser emitting part faces obliquely towards the infrared laser recognition unit.

[0030] The light-emitting part is used to provide light at night for pedestrians or vehicle drivers to see.

[0031] As a further optimization of the above solution, the infrared laser emitting unit is also equipped with a solar cell; the solar cell is electrically connected to the infrared laser emitting part and the light-emitting part.

[0032] The beneficial effects are as follows:

[0033] This invention provides an infrared laser sensing video parking barrier structure. It utilizes two infrared laser recognition units to form two intersecting, X-shaped infrared laser beams. By determining whether the two laser beams are blocked, the system identifies when a vehicle enters or leaves the parking space, which is also the recording time of the camera unit. Therefore, the camera unit does not need to collect and monitor the parking space continuously; power consumption is greatly reduced; and the simultaneous action of the two laser beams (i.e., blocking or receiving) significantly reduces misjudgments caused by factors such as pedestrians passing by.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Example 1

[0050] like Figures 1 to 3 As shown, this embodiment provides an infrared laser sensing video stake structure, applied to a non-"-shaped parking space 1. When a vehicle is parked, the front and rear sides of the parking space 1 are oriented in the same or opposite directions as the vehicle after parking.

[0051] The video parking barrier structure includes two vertical poles 2; the two vertical poles 2 are located on the left rear side and right rear side of parking space 1 respectively; the width of parking space 1 is denoted as L; the distance between the two vertical poles 2 is L.

[0052] In this embodiment, the upper side of the vertical pole 2 has two first inclined surfaces 21, which are inclined toward the parking spaces 1 on both sides respectively; each of the two first inclined surfaces 21 is equipped with an infrared laser recognition unit 4, and one of the first inclined surfaces 21 is equipped with a camera unit 3, which is used to capture an image of a parking space 1.

[0053] The vertical rod 2 is also equipped with two infrared laser recognition units 4, namely the first recognition unit 41 and the second recognition unit 42.

[0054] In this embodiment, when there are multiple consecutive parking spaces 1, on the same vertical pole 2, the first identification unit 41 corresponds to one parking space 1, and the second identification unit 42 corresponds to an adjacent parking space 1; the camera unit 3 on one vertical pole 2, the first identification unit 41, and the second identification unit 42 on the adjacent vertical pole 2 are electrically connected. That is, adjacent parking spaces 1 share one vertical pole 2.

[0055] In this embodiment, the two infrared laser recognition units 4 on the two vertical poles 2, corresponding to the same parking space 1, are installed at different heights. The two infrared laser recognition units 4 are staggered in height, and the corresponding infrared laser beams 8 are also staggered to avoid mutual interference and affecting recognition. In specific implementation, the installation heights of the first recognition unit 41 and the second recognition unit 42 on the same vertical pole 2 can be different.

[0056] In this embodiment, two infrared laser emitting units 5 are also included, located on the left front side and left rear side of the parking space 1, respectively, with a distance of 2 / 3L between them. Specifically, the infrared laser emitting unit 5 located on the left front side emits an infrared laser beam 8 towards the infrared laser recognition unit 4 located on the right rear side; the infrared laser emitting unit 5 located on the right front side emits an infrared laser beam 8 towards the infrared laser recognition unit 4 located on the left rear side. That is, one infrared laser recognition unit 4 corresponds to one infrared laser beam 8.

[0057] During operation, one end of the infrared laser beam 8 extends to the infrared laser recognition unit 4, and the other end extends to the front surface of the parking space 1; the projection of the two infrared laser beams 8 on the ground forms an X-shaped pattern.

[0058] The infrared laser recognition unit 4 can determine whether the two infrared laser beams 8 are blocked. In use, when both infrared laser recognition units 4 simultaneously switch from receiving the infrared laser beam 8 to being blocked, or simultaneously switch from being blocked to receiving, it indicates the moment when a vehicle enters or leaves parking space 1, which is also the recording time of the camera unit 3. The working principle is as follows:

[0059] When both infrared laser recognition units 4 receive the infrared laser beam 8, it means that there is no vehicle in parking space 1, and it is considered to be in the receiving state; when neither infrared laser recognition unit 4 receives the infrared laser beam 8, it means that there is a vehicle in parking space 1, and the infrared laser beam 8 is blocked by the vehicle, and it is considered to be in the blocking state.

[0060] Therefore, when the state of the infrared laser recognition unit 4 changes from simultaneous reception to simultaneous occlusion, it is considered that the vehicle has entered parking space 1; when it changes from simultaneous occlusion to simultaneous reception, it is considered that the vehicle has left parking space 1.

[0061] Ultimately, camera unit 3 does not need to collect and monitor parking space 1 for the entire time, greatly reducing power consumption; and the simultaneous action of two laser beams (i.e., blocking or receiving) can greatly reduce misjudgments caused by pedestrians or other factors.

[0062] In this embodiment, the camera unit 3 is located above the infrared laser recognition unit 4; a first mask 6 and a second mask 7 are provided on the surface of one of the first inclined surfaces 21; the first mask 6 is located above the camera unit 3; and the second mask 7 is located above the infrared laser recognition unit 4.

[0063] The first shield 6 is used to shield the camera unit 3 from wind, rain, and light, reducing the impact of the external environment on the quality of image acquisition; the second shield 7 is used to reduce the interference of the infrared laser unit directed at the infrared laser recognition unit 4 on the camera unit 3.

[0064] In this embodiment, the infrared laser emitting unit 5 is further provided with two second inclined surfaces 51; the second inclined surfaces 51 face obliquely upward; one of the second inclined surfaces 51 is provided with an infrared laser emitting part 52, and the other second inclined surface 51 is provided with a light-emitting part 53; the infrared laser emitting part 52 faces obliquely towards the infrared laser recognition unit 4. The light-emitting part 53 is used to emit light at night for pedestrians or vehicle drivers to observe.

[0065] Example 2

[0066] This implementation example Figure 4 , Figure 5 As shown, features not explained in this embodiment are explained using the method described in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is:

[0067] In this embodiment, the infrared laser recognition unit 4 is a self-reflecting infrared ranging sensor, including a transmitter 43 and a receiver 44. The transmitter 43 is used to emit an infrared laser beam 8, and the receiver 44 is used to receive the infrared laser beam 8.

[0068] The working principle is as follows:

[0069] When there is no vehicle in parking space 1, the infrared laser beam 8 emitted by the transmitter 43 is directed toward the ground and reflected in other directions, which is considered as an obstruction state; when there is a vehicle in parking space 1, the infrared laser beam 8 emitted by the transmitter 43 is directed toward the rear surface of the vehicle and reflected along the original path (or approximately the original path) toward the receiver 44, which is considered as a receiving state.

[0070] Therefore, when the state of the infrared laser recognition unit 4 changes from simultaneous reception to simultaneous occlusion, it is considered that the vehicle has left the parking space 1; when it changes from simultaneous occlusion to simultaneous reception, it is considered that the vehicle has entered the parking space 1.

[0071] Here, "obstruction" does not mean obstruction in its original sense; it is merely a name used to refer to the state of the previous technical solution, but the judgment logic is reversed.

[0072] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
