Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and specifically provides a smart charging street lamp and a charging supervision method. Background Art

[0002] Smart street lights are a type of street light system that integrates multiple intelligent functions and sensors. It aims to improve the intelligence level of urban lighting and public service capabilities. The primary function of smart street lights is to provide road lighting to ensure nighttime driving and pedestrian safety. As an important carrier for the construction of smart cities, smart street lights have broad application prospects and huge market potential.

[0003] At the same time, most municipal streets have parallel parking spaces planned on the roadside for short-term parking of vehicles. Since most of these parking spaces are unsupervised, drivers tend to drive slowly to find empty parking spaces on the roadside, which often causes traffic congestion on roads with heavy traffic. In addition, the existing parallel parking spaces on the roadside can only be used for parking. The increasing number of new energy vehicles intelligently go to centralized parking spots with charging piles for charging. If charging piles are to be set up in parallel parking spaces, it is necessary to re-lay the lines and easily block the sidewalks, which is time-consuming and laborious. In order to solve the problem of charging pile layout in the city, there are public technologies that propose to combine charging piles with smart street lights, but this technology is not mature. However, existing technologies such as patent CN112483982B-a multifunctional charging street light, CN110316009B-electric vehicle roadside charging system, etc., are simply integrating the structure of existing charging piles on street lights. According to the "Urban Road Lighting Design Specification" (GB 50034-2013), the shortest distance between street lights on municipal streets is also 25m. In the existing technology, one street light corresponds to one charging position. Obviously, the coverage rate of charging parking spaces is low, and drivers are likely to make traffic conditions worse when waiting for charging parking spaces. At the same time, due to different design concepts, the charging sockets of vehicles of different brands are at different positions on the body of the vehicle. For existing parallel parking spaces, the existing charging smart street light technology cannot adapt to different models.

[0004] Therefore, the existing technology does not take into account the actual street lamp arrangement spacing, whether there is parking space, etc., and cannot be truly used in practice. In order to solve the above problems, there is an urgent need for a smart street lamp that can monitor parking spaces and provide charging functions. Summary of the invention

[0005] The present invention aims to provide a smart charging street lamp and a charging supervision method, which can improve the parking efficiency of drivers by monitoring and indicating parking spaces and allowing the charging function to cover multiple parking spaces, and also make the urban environment more conducive to promoting new energy vehicles, thereby promoting the development of smart cities.

[0006] The technical solution of the present invention is as follows:

[0007] A smart charging street lamp comprises a lamp post, wherein a cross bar with a lighting lamp group is arranged on the top of the lamp post, the lamp post is arranged on a lamp holder, a charging module and a processing module are arranged in the lamp holder, the charging module has an extendable charging gun, the processing module is used for local data processing and cloud information transmission, a monitoring module and an indicator light module are arranged on the body of the lamp post, the monitoring module has a photoelectric sensor for monitoring the parking condition of a parking space, and the indicator light module is used for indicating the usage of the parking space and the charging module.

[0008] In this solution, the smart charging street lights are evenly set up on sections of municipal highways with parallel parking spaces to facilitate full monitoring of the parking situation of roadside parking spaces. The indicator light module lights up the corresponding color lights according to the information of the judgment monitoring module at the processing module, so that the driver can judge whether there is a parking space by observing the color lit on the lamp pole from a distance. At the same time, the indicator light module also lights up the corresponding color lights according to the use of the charging module to remind the driver from a distance, so as to avoid the driver driving slowly on the road to find a parking space and reduce traffic jams; at the same time, the charging module is equipped with an extendable charging gun, so that the charging module can cover more parking spaces, and can also adapt to different charging ports of different vehicles through the extendable charging adapter gun.

[0009] On the one hand, the smart street lamp is set on the edge of the sidewalk outside the road, while the parallel parking space is set on the inside of the road, that is, the charging module of the smart street lamp is set on one side of the parallel parking space. For vehicles with charging ports on the same side, charging is more convenient. For vehicles with charging ports on the opposite side, a longer charging gun is required, but an overly long charging hose is not conducive to storage, and it is not convenient for the driver to return the charging gun. In most cases, the charging hose is placed in a messy manner at the charging module, which is not beautiful and may damage the charging module.

[0010] To this end, preferably, the charging module is symmetrically arranged at both ends of the lamp holder, including a proximal charging gun and / or a distal charging gun, the proximal charging gun includes a power module and a plug gun connected with a charging hose; the distal charging gun includes a power module, a folding extension rod and a plug gun, the charging hose electrically connected to the power module is arranged in the folding extension rod, the charging hose extends from the folding extension rod and is connected to the plug gun, and the charging modules are symmetrically arranged to cover the parking spaces on both sides of the smart street lamp and improve the coverage rate. When the proximal and distal charging guns are arranged, for the charging guns that need to be extended for a longer distance, a folding telescopic rod is arranged, and the charging hose is partially arranged in the folding telescopic rod, which is more convenient for the storage of the charging gun and also protects the overly long charging hose to a certain extent.

[0011] On the other hand, if the charging distance is simply extended, then when charging a distant vehicle, the charging hose or folding telescopic pole may affect the vehicles parked nearby.

[0012] In this regard, preferably, the folding extension rod includes a first support rod and a second support rod, the first support rod is vertically arranged on the lamp holder through a first joint motor, the second support rod is rotatably connected to the first support rod through a second joint motor, and a bent guide head is arranged at the end of the second support rod, and the guide head can rotate along the axis of the second support rod.

[0013] In this solution, a multi-rod connection structure is set up for the folding extension rod, and the height of the far-side charging gun is raised by the first support rod to avoid interference of the charging hose or the folding telescopic rod with nearby parked vehicles when charging a vehicle in a distant parking space; and the automatic extension and storage of the folding telescopic rod is achieved by the joint motor, which is more convenient for drivers to use when parking.

[0014] Preferably, the foldable extension rod includes a storage state and an extended state. When the foldable extension rod is in the storage state, the first support rod is vertically arranged on the charging module, the second support rod is parallel to the first support rod, the second support rod is clamped in the buckle on the charging module, and the plug gun is hung on the surface of the charging module; when the foldable extension rod is in the extended state, the first support rod is 0 to 90 degrees with the horizontal plane, the second support rod is horizontally arranged, and the plug gun is inserted into the charging vehicle.

[0015] In this solution, when the folding telescopic rod is set in the storage state, the folding telescopic rod is set vertically as a whole, parallel to the lamp pole, the second support rod is drooped, and the extended charging hose and plug gun are placed in the same state as the near-side charging gun, which does not take up space and does not affect the roadside sidewalk and other facilities and equipment. When it is needed, that is, the folding telescopic rod is set in the extended state, the joint motor drives the second support arm to rotate flat, so that the entire folding extension rod is raised and extended, and the distance is adjusted by the rotation angle of the first support rod, and the first support rod can also rotate horizontally, whether it is the charging port far away on the same side or on the opposite side, the use of the remote charging gun can achieve the insertion of the plug gun for charging without hindering other vehicles. Since the existing municipal roads include main roads, secondary roads and branch roads, the height and spacing of the smart street lights set on different roads are different. In order to make a model and specification of smart street lights adapt to different road specifications, for this reason, preferably, the lamp post includes a first lamp pole and a second lamp pole. The first lamp pole is fixedly set in the lamp holder, and the second lamp pole is slidably set in the first lamp pole through a lifting mechanism. The lifting mechanism controls the second lamp pole to slide along the axis direction of the first lamp pole.

[0016] In this solution, by setting the lamp pole into a retractable structure, it is convenient to adjust the height of the smart road light source. During inspection and maintenance, there is no need for workers to climb to the highest point for inspection and maintenance. The second lamp pole can be directly controlled to descend through the lifting mechanism to reduce the height of the lamp pole and reduce the risk factor during inspection and maintenance.

[0017] Preferably, the lifting structure includes a lifting screw and a nut seat, the lifting screw is connected to the lifting motor, the nut seat is fixedly arranged below the second lamp pole, and the nut seat is arranged on the lifting screw. The lifting of the second lamp pole is automatically controlled and locked by the lifting motor, and the lifting screw is driven, which can achieve a certain degree of self-locking, thereby improving the convenience of operation and the stability of the structure.

[0018] Preferably, a sliding groove is arranged on the inner wall of the first lamp pole along the pole axis direction, a protrusion adapted to the sliding groove is arranged at the bottom of the second lamp pole, an annular groove connected to the sliding groove is arranged near the bottom on the inner wall of the first lamp pole, the protrusion can slide in the annular groove, a pressing block is arranged on the annular groove, and the pressing block is used to limit the sliding of the protrusion.

[0019] In this solution, since the second lamp pole is controlled to rise by rotating the screw rod, in order to avoid the second lamp pole rotating and causing the lifting failure, the second lamp pole is set to slide along the slide groove of the inner wall of the first lamp pole to limit the rotation of the second lamp pole, and when the second lamp pole is at the deepest point of the first lamp pole, the direction of the cross bar on the second lamp pole can be adjusted by lifting the pressing block, thereby improving the overall adaptability of the smart street lamp. After the adjustment is completed, the protrusion on the second lamp pole can be limited to the slide groove of the first lamp pole by pressing quickly.

[0020] Preferably, a waterproof fastening structure is provided at the top of the first lamp pole, and the waterproof fastening structure includes a threaded pressing block fixedly provided at the top of the first lamp pole, the thread diameter of the threaded pressing block gradually decreases from bottom to top, a sealing ring is provided between the threaded pressing block and the outer wall of the second lamp pole, the threaded pressing block is sleeved in the clamping ring, and the clamping ring is rotated so that the threaded pressing block clamps the sealing ring. After adjusting the height of the second lamp pole, the clamping ring is tightened so that the threaded pressing block on the first lamp pole is clamped to the second lamp pole, which can not only fasten the first lamp pole and the second lamp pole, but also play a role in waterproofing and dustproofing, and prevent rainwater and dust from entering the lamp holder through the gap between the first lamp pole and the second lamp pole and damaging the circuit.

[0021] In addition, a solar charging panel is arranged on the crossbar, one end of the solar charging panel is slidably arranged on the crossbar, and the other end is connected to a lifting structure, the lifting structure includes a lifting rod with a rack and a gear motor, the gear motor rotates to drive the lifting rod to move, so as to control the angle of the solar charging panel. The solar charging panel is used to provide clean energy for the lighting set, and the solar charging panel is adjusted in real time by the direction of light, so that the solar charging panel is always facing the sun, which greatly improves the utilization rate of solar energy.

[0022] A charging supervision method, based on the above-mentioned smart charging street lamp, includes the following steps:

[0023] S1. The monitoring module monitors 1 to 8 consecutive parking spaces and identifies whether there are vehicles parked in the parking spaces;

[0024] S2. After recognizing that there are vacant parking spaces, the indicator light module partially lights up the G color, and after recognizing that there are no remaining parking spaces, the indicator light module lights up the R color;

[0025] S3. When a vacant parking space is identified, the processing module determines whether the charging module is vacant. If the charging module is vacant, another part of the indicator light module lights up in color G. If the charging module is not vacant, another part of the indicator light module lights up in color G.

[0026] In this method, the monitoring module extracts information about the actual parking space and determines whether there is a vehicle parked in the corresponding parking space, so that the driver can judge whether there is a parking space by observing the color of the light on the lamp pole from a distance. At the same time, the indicator light module also lights up the corresponding color of light according to the use of the charging module to remind the driver from a distance. When an indicator light shows the same specific color, it means that there is no vacant parking space supervised by this smart street light. The driver can observe the color of the indicator light module of other smart street lights and quickly determine whether to go to park.

[0027] In the prior art, whether it is to propose a detection and positioning method for vacant parking spaces using a binocular back-projection transformation algorithm; or to establish a binocular back-projection database through images collected by a binocular camera, and perform threshold and filtering processing on obstacles therein; or to determine the vacant space information in the image using a basic image transformation algorithm to implement parking lot vacant space detection and obstacle positioning methods, more or less, there will be misjudgments due to vehicle color, obstacle obstruction, parking space line color, etc. In this regard, preferably, in step S1, the method for identifying whether there is a vehicle parked in a parking space includes

[0028] S11 enables the monitoring module to obtain monitoring images;

[0029] S12. The acquired surveillance image is smoothed by using a median filter;

[0030] S13. Calculate the parking space and vehicle status characteristic parameters in the monitoring image and extract texture features through the gray level co-occurrence matrix;

[0031] S14. Distinguishing the parking space and vehicle texture features on the monitoring image;

[0032] S15. Analyze the feature proportions of the vehicle problem, and compare the ratio of the feature proportions with the calibration threshold to determine whether there is a vehicle parked in the parking space.

[0033] In this scheme, the vacant space target detection method of public parking lot monitoring images using photoelectric sensors and median filtering can accurately determine whether there are vehicles parked in the parking space, thereby improving the indication accuracy of smart street lights.

[0034] Beneficial effects of the present invention:

[0035] 1. The indicator light module lights up the corresponding color according to the information of the judgment monitoring module at the processing module, so that the driver can judge whether there is a parking space by observing the color of the light on the lamp pole from a distance. At the same time, the indicator light module also lights up the corresponding color of light according to the use of the charging module to remind the driver from a distance, so as to avoid the driver driving slowly on the road to find a parking space and reduce traffic jams. At the same time, the charging module is provided with an extendable charging gun, so that the charging module can cover more parking spaces, and can also adapt to different charging ports of different vehicles through the extendable charging adapter gun.

DETAILED DESCRIPTION

[0047] In conjunction with the accompanying drawings, the technical solution of the present invention is clearly and completely described through the specific implementation methods of the embodiments of the present invention.

[0048] Embodiment 1:

[0049] like Figure 1 and Figure 2 A smart charging street lamp shown in the figure includes a lamp post 1, a cross bar 11 with a lighting lamp group is arranged on the top of the lamp post 1, the lamp post 1 is arranged on a lamp holder 2, a charging module 3 and a processing module are arranged in the lamp holder 2, the charging module 3 has an extendable charging gun, the processing module is used for local data processing and cloud information transmission, a monitoring module 4 and an indicator light module 5 are arranged on the body of the lamp post 1, the monitoring module 4 has a photoelectric sensor for monitoring the parking condition of the parking space, and the indicator light module 5 is used to indicate the usage of the parking space and the charging module 3.

[0050] Specifically, Figure 2The charging module 3 is symmetrically arranged at both ends of the lamp holder 2. The charging module 3 includes a near-side charging gun 31 and / or a far-side charging gun 32. The lamp holder 2 is also provided with a display 21 connected to the processing module for user operation and scanning sensing. The charging module 3 is a plate-shaped cabinet structure. Its near-side charging gun 31 includes a power module 34 and a plug gun 35 connected to a charging hose 33; the far-side charging gun 32 includes a power module 34, a folding extension rod and a plug gun 35. The charging hose 33 electrically connected to the power module 34 is arranged in the folding extension rod. The charging hose 33 extends from the folding extension rod and is connected to the plug gun 35. The charging module 3 is symmetrically arranged to cover the parking spaces on both sides of the smart street lamp and improve the coverage rate. The near-side and far-side charging guns 32 are arranged. For the charging guns that need to be extended for a longer distance, a folding telescopic rod 36 is arranged. The charging hose 33 is partially arranged in the folding telescopic rod 36, which is more convenient for the storage of the charging gun and also protects the overly long charging hose 33 to a certain extent. According to different requirements, a near-side charging gun 31 or a far-side charging gun 32 is set on a smart street lamp, preferably as follows Figure 1 As shown, a near-side charging gun 31 and a far-side charging gun 32 are symmetrically arranged to respectively assist in same-side charging and opposite-side charging on both sides of the smart street lamp, and since the far-side charging gun 32 can charge the vehicle whose charging port is arranged on the opposite side of the smart street lamp, it is preferred that the far-side charging gun 32 is arranged close to the road, while the near-side charging gun 31 is arranged away from the road.

[0051] And because the smart charging street light of the present invention is designed to be installed on sections of municipal highways with parallel parking spaces, the distance between street lights is generally set between 30m and 40m, and the length of a parallel parking space is 6m, so it is preferred that one smart street light covers 6 parking spaces, that is, it is set between 6 consecutive parking spaces, and one smart street light is set every 6 parking spaces. And the monitoring module 4 is equipped with two groups of monitors to monitor the three parking spaces at both ends respectively, and because motor vehicles are not 100% new energy vehicles, oil vehicles do not need to be charged, so one smart charging street light in this embodiment can cover up to 4 parking spaces. And if Figure 5 As shown, the indicator light module 5 is divided into a parking space light indicator group and a charging indicator light 52. Preferably, the parking space indicator light 51 displays green when there is a parking space. At this time, there are remaining charging guns, and the charging indicator light 52 also displays green. When all the charging guns are in use, the charging indicator light 52 displays red; and when there is no parking space, the parking space indicator light 51 and the charging indicator light 52 all display red.

[0052] Furthermore, the foldable extension rod provided in this embodiment specifically includes a first support rod 361 and a second support rod 362. Figure 3 and Figure 4As shown, the first support rod 361 is vertically arranged on the lamp holder 2 through the first joint motor 363, and the second support rod 362 is rotationally connected to the first support rod 361 through the second joint motor 364. A bent guide head is arranged at the end of the second support rod 362, and the guide head can rotate along the axis of the second support rod 362 to prevent the position where the charging hose 33 extends out of the second support rod 362 and the end surface of the second support rod 362 from being worn. The first joint motor 363 enables the first support rod 361 to rotate, and the first joint motor 363 can also rotate horizontally. Since motors need to be set at both the front and rear ends of the first support rod 361 and are subjected to force, sufficient strength is required, so it is made of bearing steel or other materials, and the second support rod 362 only needs to play the function of passing the charging hose 33 and is almost not subject to other external forces, so the second support rod 362 can be made of a lighter material, and the length of the second support rod 362 is longer than the first support rod 361, such as Figures 2 to 4 As shown, when the folding extension rod is in the storage state, the first support rod 361 is vertically arranged on the charging module 3, the second support rod 362 is parallel to the first support rod 361, the second support rod 362 is clamped in the buckle 365 on the side of the charging module 3, and the plug gun 35 is hung on the surface of the charging module 3, that is, in the storage state, the far-end charging gun is the same as the near-end charging gun; when the folding extension rod is in the extended state, the first support rod 361 is 0 to 90 degrees with the horizontal plane, the second support rod 362 is horizontally arranged, and the plug gun 35 is inserted into the charging vehicle.

[0053] It should be noted that when using the distal charging gun 32, since the length of the second support rod 362 after unfolding is greater than the length of the charging hose 33 extending from the second support rod 362, the user needs to first remove the plug gun 35 from the charging module 3 and hold it, then move the second support rod 362, and adjust the horizontal rotation angle of the first support rod 361 and the rotation angle of the first support rod 361 controlled by the first joint motor 363 according to the position of the charging port of the target vehicle, so as to adapt to the charging port position of various types of vehicles in the parking space.

[0054] Embodiment 2:

[0055] Since the existing municipal roads include main roads, secondary roads and branch roads, the heights and spacings of smart street lamps installed on different roads are different. In order to make a smart street lamp of a certain model and specification adaptable to different road specifications, based on the first embodiment, as shown in FIG. Figure 2As shown, the lamp post 1 includes a first lamp pole 12 and a second lamp pole 13. The first lamp pole 12 is fixedly arranged in the lamp holder 2, and the second lamp pole 13 is slidably arranged in the first lamp pole 12 by a lifting mechanism 14.

The lifting of the second lamp pole 13 is automatically controlled and locked by the lifting motor 143, and the lifting screw 141 is used for transmission, so that a certain degree of self-locking can be achieved, thereby improving the convenience of operation and the stability of the structure.

[0057] Further, such as Figure 7 As shown, a slide groove is provided on the inner wall of the first lamp pole 12 along the pole axis direction, a protrusion 131 adapted to the slide groove is provided at the bottom of the second lamp pole 13, and an annular groove 122 connected to the slide groove is provided near the bottom of the inner wall of the first lamp pole 12, and the protrusion 131 can slide in the annular groove 122, and a pressing block 123 is provided on the annular groove 122, and the pressing block 123 is used to limit the sliding of the protrusion 131. Since the second lamp pole 13 is controlled to rise by rotating the screw rod, in order to avoid the second lamp pole 13 rotating and causing the lifting failure, the second lamp pole 13 is set to slide along the slide groove on the inner wall of the first lamp pole 12 to limit the rotation of the second lamp pole 13, and when the second lamp pole 13 is at the deepest point of the first lamp pole 12, the direction of the cross bar 11 on the second lamp pole 13 can be adjusted by lifting the pressing block 123, thereby improving the overall adaptability of the smart street lamp. After adjustment, by pressing quickly, the protrusion 131 on the second lamp pole 13 can be limited to the sliding groove of the first lamp pole 12.

[0058] Furthermore, a waterproof fastening structure 15 is provided on the top of the first lamp pole 12. Figure 5As shown, the waterproof fastening structure 15 includes a threaded pressing block 151 fixedly arranged on the top of the first lamp pole 12, the thread diameter of the threaded pressing block 151 gradually decreases from bottom to top, a sealing ring 152 is arranged between the threaded pressing block 151 and the outer wall of the second lamp pole 13, the threaded pressing block 151 is sleeved in a clamping ring 153, and the clamping ring 153 is rotated to make the threaded pressing block 151 clamp the sealing ring 152. After adjusting the height of the second lamp pole 13, the threaded pressing block 151 on the first lamp pole 12 is clamped to the second lamp pole 13 by tightening the clamping ring 153, and while fastening the first lamp pole 12 and the second lamp pole 13, it can also play a waterproof and dustproof role, preventing rainwater and dust from entering the lamp holder 2 from the gap between the first lamp pole 12 and the second lamp pole 13 and damaging the circuit.

[0059] like Figure 6 As shown, a solar charging panel 16 is arranged on the cross bar 11, one end of the solar charging panel 16 is slidably arranged on the cross bar 11, and the other end is connected to a lifting structure, the lifting structure includes a lifting rod 161 with a rack and a gear motor 162, the gear motor 162 rotates, drives the lifting rod 161 to move, so as to control the angle of the solar charging panel 16. The solar charging panel 16 is used to provide clean energy for the lighting group, and the solar charging panel 16 is adjusted in real time by the direction of light, so that the solar charging panel 16 is always facing the sun, which improves the utilization rate of solar energy.

[0060] Embodiment three:

[0061] This embodiment provides a specific charging supervision method provided by a smart charging street lamp provided in Embodiment 1 and Embodiment 2, including the following steps:

[0062] S1. Monitoring module 4 monitors 1 to 8 consecutive parking spaces and identifies whether there are vehicles parked in the parking spaces;

[0063] In this step, the parking situation of the parking spaces is monitored through the monitoring module 4 according to the spacing of the smart street lights and the settings of the parking spaces. Due to the existing algorithms and methods, such as using a binocular back projection transformation algorithm to propose a detection and positioning method for vacant parking spaces; or using binocular cameras to collect images and establish a binocular back projection database, and threshold and filter the obstacles therein; or using a basic image transformation algorithm to determine the vacant space information in the image to achieve parking lot vacancy detection and obstacle positioning methods, etc., more or less, there will be misjudgments due to vehicle color, obstacle obstruction, parking space line color, etc., so another more accurate detection and judgment method and algorithm is used in this step. The details are as follows:

[0064] S11. Enable the monitoring module 4 to obtain monitoring images and separate the parking spaces into single parking spaces n for processing.

[0065] n≤N, n represents the parking space number, and N represents the total number of parking spaces.

[0066] S12. The acquired surveillance image is smoothed by using a median filter;

[0067] Among them, since the parking lot monitoring image contains a certain amount of noise and is greatly affected by factors such as lighting and environment, the image quality is not high. The photoelectric sensor in the monitoring module 4 converts the monitoring system optical signal into an electrical signal, changes the light brightness and other non-electrical physical quantity information in the image, and makes it an image that is easy to detect. The image is smoothed in combination with the median filter to reduce the impact of noise and other factors on the target detection results. The median filter is used to smooth it. The frequency domain of the monitoring image is enhanced, and a part of white noise is added to the spatial domain. The noisy monitoring image is then smoothed using the median filter, which can greatly improve the image effect.

[0068] S13. The state characteristic parameters of the parking spaces and vehicles in the monitoring image, including energy characteristics, contrast and entropy, are calculated and analyzed by gray level co-occurrence matrix and texture feature extraction is performed;

[0069] in,

[0070] (1) The energy characteristics of the parking space are:

[0071]

[0072] Ene represents the energy of the elements in the co-occurrence matrix, which reflects the specific situation of the grayscale and texture in the monitoring image to a certain extent; L represents the parameter grayscale of the texture feature of the monitoring image; P(p, q, d, θ) represents the frequency of two pixels p and q with a distance d appearing on the diagonal; the value of θ is 0°, 45°, 90°, and 135° respectively. When all values ​​in the grayscale co-occurrence matrix are the same, the value of Ene is generally small; when all values ​​are different, the value of Ene is relatively large, and when the elements in the grayscale co-occurrence matrix are densely distributed, the value of En will also be relatively large.

[0073] (2) The contrast feature of the parking space image is

[0074]

[0075] Con represents the contrast of the monitoring image, which reflects the clarity of the image to a certain extent. The clearer the image is, the larger the value of Con is. i and j represent the grayscale values ​​of the pixels in the monitoring image, and both i and j are natural numbers.

[0076] (3) The entropy of the parking space image is

[0077]

[0078] The ent represents the entropy value of the image, which reflects the complexity of the gray-scale distribution in the monitored image from the side. The larger the ent value, the more complex the gray-scale distribution of the image. When ent = 0, the complexity is also 0, indicating that the image has no texture features.

[0079] Through the analysis and calculation of the actual situation, it is concluded that when there is a vehicle in the parking space, the energy feature is smaller than when there is no vehicle, while the contrast and entropy are both larger than when there is no vehicle in the parking space. The three parameters of the obtained monitored image are integrated together to form the state feature vector of the parking space.

[0080] S14. Distinguish the texture features of the parking spaces and vehicles on the monitored image;

[0081] Among them, the monitored image of the parking space is divided into 16×16 tiles, and the tiles with vehicle texture features are represented in white, while the tiles without vehicle texture features are represented in black.

[0082] S15. Analyze the proportion of the features of the vehicle texture. When the proportion of the features is higher than the calibration value, there is a vehicle on the parking space; otherwise, there is no vehicle.

[0083] Among them, since the vehicle on the image is a whole, continuous white tiles are selected, and isolated white tiles (errors) are ignored, and the proportion B of the white tiles in all the tiles is obtained.

[0084]

[0085] W is the total number of continuous white tiles.

[0086] According to continuous tests and multi-group experimental analyses, a threshold Y = 0.3 is given. When B < Y for a single parking space, it indicates that there is no vehicle parked on the parking space; otherwise, there is a vehicle parked.

[0087] Whether there is a parking space is C, and a single parking space is counted as C n = 0 indicates that there is a vehicle parked, C n = 1 indicates that there is no vehicle parked,

[0088]

[0089] When C < N, it indicates that there are parking spaces within the supervision range of the intelligent charging street lamp; when C = N, it indicates that there are no parking spaces within the supervision range of the intelligent charging street lamp.

[0090] S2. After identifying that there is a vacant parking space, make part of the indicator light module 5 light up in color G; after identifying that there is no remaining parking space, make the indicator light module 5 light up in color R;

[0091] According to the parking situation, when there is a vacant parking space, the parking space indicator light 51 of the indicator light module 5 is preferably green in color, and when there is no vacant parking space, the parking space indicator light 51 is preferably red in color.

[0092] S3. When a vacant parking space is identified, the processing module determines whether the charging module 3 is vacant. When the charging module 3 is vacant, the charging indicator light 52 lights up in red. When the charging module 3 is not vacant, the charging indicator light 52 lights up in green.

[0093] In this method, the monitoring module 4 extracts information about the actual parking space and determines whether there is a vehicle parked in the corresponding parking space, so that the driver can judge whether there is a parking space by observing the color of the light on the lamp pole from a distance. At the same time, the indicator light module 5 also lights up the corresponding color of light according to the use of the charging module 3 to remind the driver from a distance. When an indicator light shows the same specific color, it means that the parking space supervised by this smart street lamp is not vacant, and the driver can observe the color of the indicator light module 5 of other smart street lamps to quickly determine whether to go to park.
