[0002] Street lights are an indispensable part of modern transportation systems. They are usually installed on poles or columns on both sides of the road to provide nighttime lighting to ensure the safety of pedestrians and vehicles. The main function of street lights is to improve visibility at night, help reduce accidents and enhance public safety.

[0003] The related technology will install a sensing system on the street lamp, which will automatically turn on the light when it detects a decrease in the external brightness, or automatically turn on the light after a first set time. When the second set time (such as 2 a.m.) is reached, the brightness of the street lamp will be appropriately reduced to save energy.

[0004] Regarding the above-mentioned related technologies, even in the late evening, there may be vehicles or pedestrians traveling on the road. When the brightness of the street lights is low, there are safety hazards. Summary of the invention

[0005] In order to ensure the safety of vehicles and pedestrians and reduce the energy consumption of street lamps at the same time, the present application provides a street lamp energy-saving control method, system, storage medium and energy-saving street lamp.

[0006] In a first aspect, the present application provides a street lamp energy-saving control method, which adopts the following technical solution: A street lamp energy-saving control method, comprising: In response to the first sensor detecting that a first passing vehicle enters a road intersection, adjusting a street light in the road intersection from a first brightness to a second brightness, wherein the first brightness is less than the second brightness; Acquire first lane information and first turn signal information of the first passing vehicle; Predicting a passing road for the first passing vehicle according to the first lane information to obtain a lane predicted passing road; Predicting a passing road for the first passing vehicle according to the first turn signal information to obtain a turn signal predicted passing road; When the lane predicted pass road and the turn signal predicted pass road are consistent, adjusting the street light on the lane predicted pass road from the first brightness to the second brightness; In the case where the lane predicted passing road and the turn signal predicted passing road are inconsistent, obtaining a first driving trajectory of the first passing vehicle in the road intersection; predicting the passing road of the first passing vehicle according to the first driving trajectory to obtain a trajectory predicted passing road; adjusting the street lights on the trajectory predicted passing road from the first brightness to the second brightness; In response to the second sensor detecting that the first passing vehicle leaves the road intersection and the departure time of the first passing vehicle reaches a preset time length, the street lights in the road intersection are adjusted from the second brightness to the first brightness.

[0007] By adopting the above technical solution, after the first passing vehicle enters the road intersection, it is predicted which predicted passing road the first passing vehicle will most likely take next, and the brightness of the street lights on the corresponding predicted passing road is increased. After the first passing vehicle leaves, the brightness of the street lights is reduced. Not only does it provide sufficient lighting for vehicles traveling at night, but it also reduces the brightness of the street lights when there is no first passing vehicle, thus saving resources.

[0008] Optionally, in response to a third sensor detecting that a pedestrian enters the road intersection, a street light in the road intersection is adjusted from the first brightness to the second brightness; Obtaining the location information and movement direction of the pedestrian; Predicting a path for the pedestrian to cross the road intersection according to the location information and the moving direction; In response to the third sensor detecting that the pedestrian leaves the road intersection and the pedestrian's departure time reaches the preset duration, the street lights on the pedestrian's walking road are adjusted from the second brightness to the first brightness according to the pedestrian's walking road.

[0009] By adopting the above technical solution, the pedestrian's path is predicted based on the pedestrian's location information and movement direction, and the brightness of the street lamps on the path is adjusted. This technical solution not only provides sufficient lighting for pedestrians traveling at night, but also reduces the brightness of the street lamps when there are no pedestrians, thus saving resources.

[0010] Optionally, when the predicted passage road of the first passing vehicle is the same as the passage road of the pedestrian, the first driving trajectory of the first passing vehicle is obtained, and the moving trajectory of the pedestrian is obtained, and the predicted passage road is the lane predicted passage road, the turn signal predicted passage road or the trajectory predicted passage road; Determining whether the first driving trajectory intersects with the moving trajectory; If so, determining a target street lamp located in the opposite direction of the moving direction on the travel road; The target street light is controlled to flash.

[0011] By adopting the above technical solution, when the moving trajectory of the first passing vehicle intersects with that of the pedestrian, the target street light is controlled to flash to remind the driver of the first passing vehicle to pay attention to the pedestrians on the road, thereby reducing the probability of accidents as much as possible.

[0012] Optionally, before the first passing vehicle enters the road intersection, a first traveling speed of the first passing vehicle is acquired; When the first driving speed is greater than a preset speed threshold, obtaining a current road of the first passing vehicle; When the pedestrian is heading toward the current road, controlling the street lights corresponding to the current road at the road intersection to flash; In the case that the pedestrian is not heading towards the current road, the street lights at the road intersection corresponding to the current road are adjusted to the second brightness, and the street lights at the road intersection that do not correspond to the current road are adjusted to the third brightness, wherein the third brightness is less than the second brightness and the third brightness is greater than the first brightness; the street lights at the road intersection corresponding to the current road are controlled to flash.

[0013] By adopting the above technical solution, before the first passing vehicle enters the road intersection at a faster speed, the brightness of the corresponding street lamps in the road intersection is adjusted to remind pedestrians that a vehicle is about to enter the road intersection, ensuring that pedestrians have a certain amount of reaction time and reducing the probability of accidents as much as possible.

[0014] Optionally, in response to the distance between the second passing vehicle and the road intersection being less than a preset distance threshold, obtaining the influencing road where the second passing vehicle is located; predicting a second driving trajectory of the second passing vehicle according to second lane information and second turn signal information corresponding to the second passing vehicle; When the second driving trajectory matches the predicted passage road of the first passing vehicle, the street lights corresponding to the affected road at the road intersection are controlled to flash.

[0015] By adopting the above technical solution, when there are other second passing vehicles entering the road intersection, the corresponding street lights in the road intersection are flashed to remind the drivers of the first passing vehicles to pay attention to the second passing vehicles, thereby reducing the probability of accidents.

[0016] Optionally, obtaining the type of headlights used by the second passing vehicle; When the type of the vehicle light is a high beam light, obtaining a second travel speed of the second passing vehicle and a travel distance from the second passing vehicle to the road intersection; Obtaining the arrival time of the second passing vehicle according to the ratio of the driving distance to the second driving speed; Calculating the brightness change rate of the street lamp according to the preset brightness, the second brightness and the arrival time; The brightness of the street lamps corresponding to the affected road at the road intersection is controlled to increase according to the brightness change rate.

[0017] By adopting the above technical solution, the brightness of the corresponding street lights at the road intersection is gradually increased, so that the driver of the first passing vehicle has time to adapt to the strong light environment, reducing the probability of the driver being affected by the high beam of the second passing vehicle, thereby ensuring the driving safety of the driver of the first passing vehicle.

[0018] Optionally, when the second passing vehicle enters the road intersection, monitoring the brightness of the headlights of the second passing vehicle; When the brightness of the vehicle light is greater than a preset brightness threshold, obtaining the real-time position of the second passing vehicle; determining candidate street lamps located on the affected road; The candidate street lamp is controlled to illuminate toward the real-time position.

[0019] By adopting the above technical solution, the position of the second passing vehicle is located in real time using street lights, so that the driver of the first passing vehicle can timely grasp the accurate position of the second passing vehicle, thereby reducing the probability of collision between the first passing vehicle and the second passing vehicle.

[0021] By adopting the above technical solution, after the first passing vehicle enters the road intersection, it is predicted which predicted passing road the first passing vehicle will most likely take next, and the brightness of the street lights on the corresponding predicted passing road is increased. After the first passing vehicle leaves, the brightness of the street lights is reduced. Not only does it provide sufficient lighting for vehicles traveling at night, but it also reduces the brightness of the street lights when there is no first passing vehicle, thus saving resources.

[0022] In a third aspect, the present application provides an energy-saving street lamp, which adopts the following technical solution: An energy-saving street lamp stores a computer program that can be loaded by a processor and execute any one of the above methods.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: After the first passing vehicle enters the road intersection, it will predict which predicted road the first passing vehicle will most likely take next, and increase the brightness of the street lights on the corresponding predicted road. After the first passing vehicle leaves, the brightness of the street lights will be reduced. This not only provides sufficient lighting for vehicles traveling at night, but also reduces the brightness of street lights when there is no first passing vehicle, thus saving resources. According to the location information and movement direction of pedestrians, the paths that pedestrians will take are predicted, and the brightness of street lights on the paths that pedestrians will take is adjusted. This technical solution not only provides sufficient lighting for pedestrians traveling at night, but also reduces the brightness of street lights when there are no pedestrians, thus saving resources. When there are other second passing vehicles entering the road intersection, the corresponding street lights in the road intersection are flashed to remind the drivers of the first passing vehicles to pay attention to the second passing vehicles, so as to reduce the probability of accidents.

[0036] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figures 1 to 11 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] The present application embodiment discloses a schematic diagram of the structure of an energy-saving street lamp. Figure 1 and Figure 2 The energy-saving street lamp includes a mounting plate 1, a lamp 2 arranged on the mounting plate 1 and a fixing structure 3. The lamp 2 is arranged on one side of the mounting plate 1, and the lamp 2 is composed of a plurality of bulbs. One end of the mounting plate 1 is connected to the first end of the fixing structure 3, and the second end of the fixing structure 3 is used to be fixed on the lamp post.

[0038] Optionally, the mounting plate 1 is connected to the fixed structure 3 via a curved gear 4, so that the mounting plate 1 can rotate around the connecting end of the curved gear 4, thereby adjusting the lighting area of ​​the energy-saving street lamp.

[0039] Optionally, a sensor and a control system are installed on the lamp post, wherein the sensor includes an infrared sensor or a laser radar, and the control system is used to control the on and off of the lamp 2. Furthermore, the control system is also connected to a camera, and the camera is used to obtain images or videos of the road intersection.

[0040] The present application embodiment discloses a flow chart of a street lamp energy-saving control method. Figure 3 , the method comprising: Step S301: In response to a first sensor detecting that a first passing vehicle enters a road intersection, a street light in the road intersection is adjusted from a first brightness to a second brightness, wherein the first brightness is less than the second brightness.

[0041] It should be noted that the method provided in the embodiment of the present application needs to be applied in a preset time period, for example, from 1 a.m. to 3 a.m. At this time, the number of pedestrians and vehicles on the road is relatively small.

[0042] The first sensor is a camera. Optionally, the first sensor is arranged on a lamp post of a street lamp. In some other embodiments, the first sensor may further include an infrared sensor or a laser radar.

[0043] A road intersection is a place where two or more roads intersect, meet or intersect. For example, road intersections include cross intersections, T-intersections, roundabouts, diagonal intersections, interchanges and forks. The scope of road intersections can be adjusted by relevant personnel according to actual needs.

[0044] For example, please refer to Figure 4 A plurality of street lamps 401 are arranged at the road intersection, and each street lamp is provided with a sensor. When the sensor on the street lamp 401 detects that a first passing vehicle 402 enters the road intersection, all the street lamps 401 at the road intersection are adjusted from a first brightness to a second brightness.

[0045] Step S302: Acquire first lane information and first turn signal information of a first passing vehicle.

[0046] The first lane information is used to indicate the type of lane that the first passing vehicle is in. Exemplarily, the types of lanes include a straight lane, a left-turn lane, and a right-turn lane.

[0047] The first turn signal information is used to indicate the type of the turn signal used by the first passing vehicle. Exemplarily, the types of turn signals include left turn signal, right turn signal, and not turned on.

[0048] In some embodiments, a real-time image including a first passing vehicle is acquired through a camera. The use status of a turn signal of the first passing vehicle is identified from the real-time image to obtain first turn signal information. The positional relationship between the first passing vehicle and a ground lane line is identified from the real-time image to obtain first lane information.

[0049] In some embodiments, the distance and direction from the first passing vehicle to the infrared sensor are acquired through an infrared sensor (or a laser radar), and the lane corresponding to the position of the first passing vehicle is calculated based on the aforementioned distance and direction to obtain the first lane information.

[0050] Step S303: predicting the passageway of the first passing vehicle according to the first lane information to obtain the lane predicted passageway.

[0051] Optionally, when the first lane information corresponds to a straight lane, the first passing vehicle will keep going straight at the road intersection, and the lane predicts that the passing road is a straight road. When the first lane information corresponds to a right-turn lane, the first passing vehicle will turn right at the road intersection, and the lane predicts that the passing road is a right-turn road. When the first lane information corresponds to a left-turn lane, the first passing vehicle will turn left at the road intersection, and the lane predicts that the passing road is a left-turn road.

[0052] For example, please refer to Figure 4 If the first passing vehicle 402 is located in the straight lane, the lane prediction pass road is road 41. If the first passing vehicle 402 is located in the right turn lane, the lane prediction pass road is road 42. If the first passing vehicle 402 is located in the left turn lane, the lane prediction pass road is road 43.

[0053] Step S304: predicting the travel road of the first passing vehicle according to the first turn signal information to obtain the turn signal predicted travel road.

[0054] Optionally, when the first turn signal information is not turned on, the first passing vehicle will keep going straight at the road intersection, and the turn signal predicts that the passing road is a straight road. When the first turn signal information corresponds to a left turn signal, the first passing vehicle turns right at the road intersection, and the turn signal predicts that the passing road is a right turn road. When the first turn signal information corresponds to a left turn signal, the first passing vehicle turns left at the road intersection, and the turn signal predicts that the passing road is a left turn road.

[0055] Step S305: When the lane predicted passage road and the turn signal predicted passage road are consistent, the street lights on the lane predicted passage road are adjusted from the first brightness to the second brightness.

[0056] When the lane predicted passageway and the turn signal predicted passageway are consistent, it can be predicted that the first passing vehicle will enter the lane predicted passageway. Therefore, in order to ensure the safe driving of the first passing vehicle on the first passageway, the street lights on the lane predicted passageway are increased from the first brightness to the second brightness.

[0057] Step S306: When the lane predicted passing road and the turn signal predicted passing road are inconsistent, obtaining a first driving trajectory of the first passing vehicle in the road intersection.

[0058] When the lane predicted passing road and the turn signal predicted passing road are inconsistent, it is difficult to determine which road the first passing vehicle will drive to. Therefore, in this case, it is necessary to determine which road the first passing vehicle will drive to based on the actual behavior of the first passing vehicle.

[0059] Optionally, a camera is used to continuously capture the driving route of the first passing vehicle to obtain a first driving trajectory.

[0060] Optionally, an infrared sensor (or a laser radar) is used to continuously monitor the vehicle position of the first passing vehicle, and a first driving trajectory is obtained based on changes in the vehicle position over time.

[0061] Step S307: predicting the travel path of the first passing vehicle according to the first driving trajectory to obtain a trajectory predicted travel path.

[0062] Optionally, a travel road for the first passing vehicle is predicted according to a time series generation order of the first driving trajectory to obtain a trajectory predicted travel road.

[0063] Step S308: adjusting the street lights on the trajectory predicted road from the first brightness to the second brightness.

[0064] After determining the trajectory prediction road, it can be determined that the first passing vehicle will enter the trajectory prediction road. Therefore, to ensure safe driving on the first passing road, the street lights on the trajectory prediction road are increased from the first brightness to the second brightness.

[0065] Step S309: In response to the second sensor detecting that the first passing vehicle leaves the road intersection and the departure time of the first passing vehicle reaches a preset time length, the street light in the road intersection is adjusted from the second brightness to the first brightness.

[0066] The second sensor and the first sensor may be the same sensor or different sensors. The second sensor and the first sensor may be of the same type or different types. Optionally, the second sensor is an infrared sensor, a laser radar or a camera.

[0067] The preset duration is a preset empirical value, for example, the preset duration is 1 minute or 2 minutes.

[0068] In summary, after the first passing vehicle enters the road intersection, it is predicted which predicted passing road the first passing vehicle will most likely take next, and the brightness of the street lights on the corresponding predicted passing road is increased. After the first passing vehicle leaves, the brightness of the street lights is reduced. This not only provides sufficient lighting for vehicles traveling at night, but also reduces the brightness of the street lights when there is no first passing vehicle, which plays a role in saving resources.

[0069] In the following embodiments, since pedestrians are also used on the road at night in addition to vehicles, the safe passage of pedestrians also needs to be considered. Figure 1 . Reference Figure 5 , the method comprising: Step S501: In response to a third sensor detecting that a pedestrian enters a road intersection, a street light in the road intersection is adjusted from a first brightness to a second brightness.

[0070] Optionally, the third sensor is an infrared sensor, a lidar or a camera.

[0071] Optionally, the third sensor and the first sensor may be sensors of the same type or sensors of different types. When the third sensor and the first sensor are sensors of the same type, it is also necessary to distinguish whether the object is a vehicle or a pedestrian. For example, when the third sensor and the first sensor are both laser radars, the shape of the object can be obtained by the laser radar, and the object can be determined based on the shape to be a vehicle or a pedestrian. For example, when the third sensor and the first sensor are both cameras, an object recognition operation is performed on the real-time image obtained by the camera to determine whether the object in the real-time image is a vehicle or a pedestrian.

[0072] Step S502: Obtain the location information and movement direction of the pedestrian.

[0073] In some embodiments, a real-time image including a pedestrian is acquired through a camera, a position of the pedestrian is identified from the real-time image, and the position information of the pedestrian is obtained, and the pedestrian is identified from the real-time image to obtain the first lane information.

[0074] In some embodiments, the distance and direction from the pedestrian to the laser radar are obtained by an infrared sensor (or laser radar). According to the aforementioned distance and direction, the location information of the pedestrian is obtained. According to the change of the aforementioned distance and direction over time, the moving direction of the pedestrian is obtained.

[0075] Step S503: predicting the pedestrian's crossing path at the road intersection based on the location information and the moving direction.

[0076] Optionally, the location information is used as a starting point to determine the road in the moving direction, thereby obtaining the road that the pedestrians travel at the road intersection.

[0077] For example, please refer to Figure 4 , the moving direction of pedestrian 403 is shown by the arrow in the figure, and pedestrian 403 needs to cross road 42, so the crossing road is road 42.

[0078] Step S504: According to the pedestrian's walking road, the street lamp on the walking road is adjusted from the second brightness to the first brightness.

[0079] In this embodiment, it can be predicted that pedestrians will cross the through road, so in order to ensure the safety of pedestrians crossing the through road, the street lights on the through road are increased from the first brightness to the second brightness. Further, in response to the third sensor detecting that the pedestrian leaves the road intersection and the pedestrian's departure time reaches a preset time, the street lights on the through road will be adjusted from the second brightness to the first brightness.

[0080] In summary, based on the location information and movement direction of pedestrians, the paths that pedestrians will travel are predicted, and the brightness of street lamps on the paths they will travel is adjusted. This technical solution not only provides sufficient lighting for pedestrians traveling at night, but also reduces the brightness of street lamps when there are no pedestrians, thus saving resources.

[0081] In the following embodiment, when the first passing vehicle and the pedestrian are both located at the road intersection, the first passing vehicle may hit the pedestrian, causing an accident. Figure 2 . Reference Figure 6 , the method comprising: Step S601: When the predicted passage road of the first passing vehicle is the same as the passage road of the pedestrian, obtain the first driving trajectory of the first passing vehicle and the moving trajectory of the pedestrian, and the predicted passage road is a lane predicted passage road, a turn signal predicted passage road or a trajectory predicted passage road.

[0082] The method for obtaining the first driving trajectory of the first passing vehicle can refer to Figure 3 Step S606 of the illustrated embodiment will not be described in detail here.

[0083] Optionally, a camera is used to continuously capture the movement routes of pedestrians to obtain the movement trajectories of pedestrians.

[0084] Optionally, an infrared sensor (or lidar) is used to continuously monitor the pedestrian's position, and the pedestrian's movement trajectory is obtained based on the change of the pedestrian's position over time.

[0085] Step S602: Determine whether the first driving trajectory intersects with the moving trajectory.

[0086] If the first driving trajectory intersects with the moving trajectory, then executing step S603 to step S604; If the first driving trajectory does not intersect with the moving trajectory, the process of this embodiment ends.

[0087] Step S603: If yes, then determine a target street lamp located in the opposite direction of the moving direction on the traveling road.

[0088] For example, please refer to Figure 4 The moving direction of pedestrian 403 is indicated by the arrow in the figure, and the target street lamp 4011 is a street lamp located in the opposite direction of the moving direction.

[0089] Step S604: Control the target street light to flash.

[0090] Optionally, the target street light is controlled to flash a preset number of times. Alternatively, the target street light is controlled to flash for a preset time.

[0091] On the one hand, controlling the target street light to flash can remind the driver of the first passing vehicle that there may be pedestrians on the passing road, so as to reduce the probability of the first passing vehicle hitting the pedestrians. On the other hand, the target street light is located in the opposite direction of the pedestrian's movement direction, which has little impact on the normal movement of the pedestrian.

[0092] In summary, when the moving trajectories of the first passing vehicle and the pedestrian intersect, the target street light is controlled to flash to remind the driver of the first passing vehicle to pay attention to the pedestrian on the road, thereby reducing the probability of accidents as much as possible.

[0093] In the following embodiments, if the speed of the first passing vehicle is high, the driver of the first passing vehicle may fail to find the pedestrian in time, which may lead to an accident. Therefore, it is also very important for the pedestrian to know the position of the first passing vehicle. Figure 3 . Reference Figure 7 , the method comprising: Step S701: Before a first passing vehicle enters a road intersection, a first driving speed of the first passing vehicle is obtained.

[0094] Exemplarily, when the distance between the first passing vehicle and the road intersection is less than a preset minimum distance value, the first driving speed of the first passing vehicle is measured.

[0095] Step S702: When the first driving speed is greater than a preset speed threshold, the current road of the first passing vehicle is obtained.

[0096] The preset speed threshold is a preset empirical value. For example, the preset speed threshold is 45km / h or 50km / h. Further, the preset speed threshold can be adjusted according to actual needs.

[0097] Step S703: When the pedestrian is heading towards the current road, the street lights corresponding to the current road at the road intersection are controlled to flash.

[0098] Optionally, a real-time image including pedestrians is acquired through a camera, and the direction of the pedestrians is read through the real-time image.

[0099] Optionally, the number of flashing times of the street lamp corresponding to the current road at the road intersection is controlled to reach a preset number of times. Alternatively, the flashing time of the street lamp corresponding to the current road at the road intersection is controlled to reach a preset time.

[0100] When pedestrians are heading towards the current road, they can directly observe the situation ahead, so the street lights corresponding to the current road in the road intersection are directly controlled to flash. Pedestrians can immediately know that the street lights are flashing. At this time, pedestrians can promptly know that the first passing vehicle is about to enter the road intersection, so that pedestrians can make corresponding responses.

[0101] Step S704: When the pedestrian is not heading towards the current road, the street lights at the road intersection corresponding to the current road are adjusted to the second brightness, and the street lights at the road intersection not corresponding to the current road are adjusted to the third brightness, wherein the third brightness is less than the second brightness and greater than the first brightness.

[0102] When pedestrians are not heading towards the current road, the street lights at the road intersection corresponding to the current road are adjusted to the second brightness, and the street lights at the road intersection not corresponding to the current road are adjusted to the third brightness, so that the current road can be highlighted by the brightness of the street lights.

[0103] Step S705: Control the street lights corresponding to the current road at the road intersection to flash.

[0104] In poor light conditions at night, brighter street lights are more likely to attract pedestrians' attention. Therefore, pedestrians are more likely to notice that the street lights corresponding to the current road are flashing, allowing pedestrians to obtain information about the first passing vehicle approaching the road intersection in a timely manner.

[0105] In summary, before the first passing vehicle enters the road intersection at a faster speed, the brightness of the corresponding street lamps in the road intersection is adjusted to remind pedestrians that a vehicle is about to enter the road intersection, ensuring that pedestrians have a certain reaction time and reducing the probability of accidents as much as possible.

[0106] In the following embodiments, multiple different vehicles entering a road intersection is also a common practical scenario. In order to ensure the physical and mental health and property safety of the driver in each vehicle, the driver in the vehicle can be informed by the street lamp from which direction other vehicles will enter the road intersection. Figure 4 . Reference Figure 8 , the method comprising: Step S801: In response to the distance between the second passing vehicle and the road intersection being less than a preset distance threshold, obtaining the influencing road where the second passing vehicle is located.

[0107] The preset distance threshold is a preset empirical value. Exemplarily, the preset distance threshold is 50m or 100m.

[0108] The affected road refers to the road where the second passing vehicle is located.

[0109] Step S802: predicting a second driving trajectory of the second passing vehicle according to the second lane information and the second turn signal information corresponding to the second passing vehicle.

[0110] The method for obtaining the second lane information and the second turn signal information corresponding to the second passing vehicle is similar to the method for obtaining the first lane information and the first turn signal information. Figure 3 The illustrated embodiments will not be described in detail here.

[0111] Step S803: When the second driving trajectory matches the predicted passing road of the first passing vehicle, the street lights corresponding to the affected road at the road intersection are controlled to flash.

[0112] Optionally, when the second driving trajectory and the predicted passable road have an intersection, it is confirmed that the second driving trajectory matches the predicted passable road of the first passing vehicle. Alternatively, when the shortest distance between the second driving trajectory and the predicted passable road is less than a preset minimum distance value, it is confirmed that the second driving trajectory matches the predicted passable road of the first passing vehicle.

[0113] Optionally, the number of flashing times of the street lamps corresponding to the affected roads at the road intersection is controlled to reach a preset number of times. Alternatively, the flashing time of the street lamps corresponding to the affected roads at the road intersection is controlled to reach a preset time.

[0114] In summary, when there are other second passing vehicles entering the road intersection, the corresponding street lights in the road intersection are flashed to remind the drivers of the first passing vehicles to pay attention to the second passing vehicles, so as to reduce the probability of accidents.

[0115] In the following embodiment, when the second passing vehicle enters the road intersection, the light of the second passing vehicle may affect the driver of the first passing vehicle, making it difficult for the driver to observe the road conditions in a short period of time, thereby affecting the driver's driving safety. To solve this problem, the present application embodiment discloses a process diagram of a street lamp energy-saving control method. Figure 5 . Reference Fig. 9 , the method comprising: Step S901: Obtain the type of headlights used by the second passing vehicle.

[0116] Types of lights include high beam, low beam and hazard warning flashers.

[0117] Exemplarily, a real-time image of the second passing vehicle is obtained through a camera, and the headlight brightness, headlight color, and headlight emission frequency of the second passing vehicle are identified from the real-time image. When the headlight color is red and the headlight emission frequency indicates that the headlight is flashing, it is determined that the headlight used by the second passing vehicle is a hazard warning flasher. When the headlight color is white, the headlight emission frequency indicates that the headlight is always on, and the headlight brightness is greater than a preset brightness classification value, it is determined that the headlight used by the second passing vehicle is a high beam. When the headlight color is white, the headlight emission frequency indicates that the headlight is always on, and the headlight brightness is less than a preset brightness classification value, it is determined that the headlight used by the second passing vehicle is a low beam.

[0118] Step S902: When the type of the vehicle light is a high beam, obtain a second driving speed of the second passing vehicle and a driving distance of the second passing vehicle to the road intersection.

[0119] In the case where the headlight type is a high beam, due to the high brightness of the high beam, it will emit a concentrated and strong light beam, which is easy to interfere with the sight of the driver of the first passing vehicle. Therefore, it is necessary to process the street lights at the road intersection to reduce the adverse effects of the high beam.

[0120] In some other embodiments, when the type of the vehicle light is a low beam light, the process of this embodiment is terminated.

[0121] In some other embodiments, when the type of vehicle lights is a hazard warning flasher, the street lights corresponding to the affected roads at the road intersection are controlled to flash. Furthermore, according to the maximum brightness of the hazard warning flasher, the brightness of the street lights corresponding to the affected roads at the road intersection is reduced so that the brightness of the corresponding street lights is less than the aforementioned maximum brightness.

[0122] Step S903: Obtain the arrival time of the second passing vehicle according to the ratio of the driving distance to the second driving speed.

[0123] For example, the ratio of the driving distance to the second driving speed is calculated to obtain the arrival time of the second passing vehicle.

[0124] Step S904: Calculate the brightness change rate of the street lamp according to the preset brightness, the second brightness and the arrival time.

[0125] Exemplarily, the difference between the preset brightness and the second brightness is calculated to obtain the difference brightness; and the ratio of the difference brightness to the arrival time is calculated to obtain the brightness change rate of the street lamp.

[0126] Step S905: Control the brightness of the street lamps corresponding to the affected roads at the road intersection to increase according to the brightness change rate.

[0127] When the brightness of the street lamps corresponding to the affected roads at the road intersection is increased according to the brightness change rate, it can help the driver of the first passing vehicle gradually adapt to the strong light environment to reduce the probability of the driver being affected by the high beam of the second passing vehicle.

[0128] To sum up, the brightness of the corresponding street lights at the road intersection is gradually increased, so that the driver of the first passing vehicle has time to adapt to the strong light environment, reducing the probability of the driver being affected by the high beam of the second passing vehicle, and ensuring the driving safety of the driver of the first passing vehicle.

[0129] In the following embodiment, after the second passing vehicle enters the road intersection, the position of the second passing vehicle can be located in real time to ensure that the driver of the first passing vehicle can obtain the position of the second passing vehicle in real time. Figure 6 . Reference Fig.10 , the method comprising: Step S1001: When a second passing vehicle enters the road intersection, monitor the brightness of the headlights of the second passing vehicle.

[0130] Optionally, a real-time image including the second passing vehicle is acquired through a camera, and the headlight brightness of the second passing vehicle is identified through the real-time image.

[0131] Step S1002: When the vehicle light brightness is greater than a preset brightness threshold, the real-time position of the second passing vehicle is obtained.

[0132] The preset brightness threshold is a preset experience value. Relevant personnel can adjust the preset brightness threshold according to actual circumstances.

[0133] Optionally, a real-time image including the second passing vehicle is acquired through a camera, and a real-time position of the second passing vehicle is acquired through the real-time image.

[0134] Step S1003: Determine candidate street lamps located on the affected road.

[0135] Optionally, various street lamps located on the affected road are determined; and a street lamp closest to the second passing vehicle is selected from the aforementioned street lamps as a candidate street lamp.

[0136] Optionally, a candidate street lamp is arranged on each road at the road intersection, wherein the brightness of the light emitted by the candidate street lamp is greater than the brightness of the light emitted by other street lamps. Further, the candidate street lamp can generate a concentrated light beam, for example, the candidate street lamp adopts a spotlight.

[0137] Step S1004: Control the candidate street lamp to illuminate the real-time position.

[0138] Optionally, the illumination direction of the candidate street lamp is controlled so that the illumination direction is aligned with the real-time position for illumination in real time. Optionally, in order to ensure the driving safety of the second passing vehicle, the candidate street lamp is controlled to illuminate the bottom area of ​​the second passing vehicle.

[0139] Furthermore, before controlling the candidate street lamp to illuminate the real-time position, the brightness of the candidate street lamp is adjusted to a preset illumination brightness. The preset illumination brightness is greater than the brightness of other street lamps. At this time, the driver of the first passing vehicle can accurately obtain the illumination area of ​​the candidate street lamp to determine the position of the second passing vehicle, helping the driver to avoid the second passing vehicle.

[0140] In summary, the use of street lights to locate the position of the second passing vehicle in real time enables the driver of the first passing vehicle to promptly grasp the accurate position of the second passing vehicle, thereby reducing the probability of a collision between the first passing vehicle and the second passing vehicle.

[0142] In summary, after the first passing vehicle enters the road intersection, it is predicted which predicted passing road the first passing vehicle will most likely take next, and the brightness of the street lights on the corresponding predicted passing road is increased. After the first passing vehicle leaves, the brightness of the street lights is reduced. This not only provides sufficient lighting for vehicles traveling at night, but also reduces the brightness of the street lights when there is no first passing vehicle, which plays a role in saving resources.
