Abstract
Description
Technical Field
[0001] The present application relates to the field of intelligent transportation technology, and in particular to a street lamp control method, device, electronic device, and computer-readable storage medium. Background Art
[0002] At present, the country's road infrastructure is huge, and urban road lighting accounts for 30% of the total lighting power consumption and 10% of the country's total power consumption. With the continuous advancement of smart cities, energy conservation and environmental protection, urban image, and intelligent management are receiving increasing attention. Combined with the current lighting status and various problems caused by power shortages, the concept of "on-demand lighting and fine management" has been proposed, that is, the smart street light system.
[0003] Energy conservation and emission reduction have become a key goal in economic development. With technological advancements, energy-saving lamps and control methods are constantly evolving, and intelligent streetlights offer significant advantages in this regard. Currently, diverse streetlight control methods are available, including grouping, time-based, regional, temporary, automatic, and cross-lighting. These control methods enable on-demand control of streetlights, achieving energy savings to a certain extent. Regarding power conservation, current energy-saving measures are achieved through dimming, which reduces the brightness of streetlights and uses energy-saving lamps to control them.
[0004] The current street light control method can take lighting control measures in different areas based on the current time period, the current lighting environment, and experience. These control methods are all achieved through the use of sensors to sense the current environmental factors and manual control. They cannot achieve more refined management and control, and therefore still cause a large amount of lighting waste and uneven distribution of some lighting resources.
[0005] V2X (Vehicle to X) communication technology is an emerging communication method that uses PC5's direct communication technology to achieve short-distance, high-concurrency, and low-latency data transmission. It is commonly used for data exchange, information sharing, and vehicle control between intelligent connected vehicles and smart roads. A mainstream form of V2X communication, V2X communication is vehicle-to-road communication. Compared to base station communication based on the UU interface, it has the advantages of shorter transmission latency, lower resource consumption, and no interference from intermediate base station signal coverage.
[0006] The intelligent vehicle-road cooperative system adopts advanced V2X communication and new generation Internet technologies to implement all-round dynamic real-time information interaction between vehicles and roads, and conducts active vehicle safety control and road collaborative management based on the collection and integration of dynamic traffic information in all time and space, improving information sharing and collaborative processing between people, vehicles and roads. It is a safe, efficient and energy-saving smart transportation system.
[0007] Existing V2X communication-based solutions for controlling streetlights primarily rely on roadside controllers receiving V2X data to control the light intensity of streetlights. However, due to the broadcast nature of V2X, all streetlights within the broadcast range will be turned on upon receiving V2X data, leading to greater resource waste. Furthermore, existing methods are unable to achieve more refined streetlight control. Summary of the Invention

[0049] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0050] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.
[0051] The embodiment of the present application provides a streetlight control method, which is executed by a roadside terminal, such as Figure 1 As shown, a flowchart of a street lamp control method in an embodiment of the present application is provided, and the method at least includes the following steps S110 to S140:
[0052] Step S110: Acquire the streetlight control information of the road end.
[0053] The streetlight control method of the present embodiment can be executed by the roadside controller in a roadside unit (RSU). RSUs can be deployed on both sides of a road and can collect, analyze, and monitor information about vehicles and pedestrians on a nearby road.
[0054] When controlling street lights, it is necessary to first obtain the street light control information of the road end itself. The street light control information of the road end can specifically include information collected by sensors deployed on the road side and relevant configuration information of the street light control, etc. The street light control information of the road end can serve as the basis for street light control in the embodiment of this application.
[0055] Step S120: Acquire the path planning information and current positioning information sent by the vehicle end according to the street light control information at the road end.
[0056] Based on the street light control information obtained in the previous steps, it is necessary to further obtain the path planning information and current positioning information reported by the vehicle. The path planning information includes the vehicle's driving trajectory within a certain driving area, and the current positioning information can include the vehicle's current specific location such as longitude and latitude coordinates and the vehicle's current driving speed.
[0057] Step S130, determining the target vehicle corresponding to the road section where the road end is located based on the path planning information, wherein the target vehicle includes at least one type of vehicle that is about to enter the road section where the road end is located, a vehicle that has entered the road section where the road end is located, and a vehicle that is leaving the road section where the road end is located.
[0058] The path planning information reported by the vehicle side can provide a basis for more refined adjustment of the street light control at the road side. Since each road side in the embodiment of the present application is responsible for controlling and coordinating the street light lighting on the road section where it is located, the road side can determine which specific target vehicles correspond to its own road section based on the path planning information.
[0059] In order to achieve refined control of street lights, the target vehicles here can be divided into three types. The first type is vehicles that are about to enter the road section where the road end is located. By taking them as target vehicles, the street lighting can be coordinated and adjusted in advance for these vehicles. The second type is vehicles that have already entered the road section where the road end is located. The third type is at least one of the following types of vehicles that are leaving the road section where the road end is located. Taking them as target vehicles is mainly to avoid adjusting the street lighting status too early or too late and to ensure timely adjustment of the street lighting status.
[0060] Step S140: controlling the lighting status of the street lamps on the road section where the road end is located according to the current positioning information of the target vehicle.
[0061] After the target vehicle is determined, the streetlight lighting status of the road section where the road end is located can be adjusted more finely based on the current positioning information of the target vehicle. The adjustments here can include, for example, adjusting the streetlight illumination intensity and the streetlight switch status, etc.
[0062] The street light control method of the embodiment of the present application uses the path planning information and current positioning information reported by the vehicle side to perform more refined control over the street light lighting status, reducing the resource waste of street lights in scenarios such as idle roads, and at the same time realizing the coordinated control of the street light lighting status between the vehicle side and the road side, reducing human intervention, and improving the control efficiency and utilization rate of street lights.
[0063] The street light control method of the present application is suitable for idle road scenarios with relatively small traffic volume. In this scenario, the demand for energy-saving control of street lights and the adjustment space are greater. It can not only meet the lighting requirements of passing vehicles at night and in low-light conditions, but also avoid energy waste caused by continuously turning on the lights.
[0064] This application is also suitable for road scenes with heavy traffic. It is continuously turned on when vehicles are concentrated, and is selectively turned on according to the situation during time periods such as early morning when traffic volume is reduced, so as to meet the lighting requirements of passing vehicles and avoid energy waste caused by continuously turning on the lights.
[0065] In some embodiments of the present application, the street light control information of the road end includes sensor collection information and street light control configuration information, and obtaining the path planning information and current positioning information sent by the vehicle end based on the street light control information of the road end includes: determining whether to turn on the street lights of the road section where the road end is located based on the sensor collection information and the street light control configuration information; and when it is determined to turn on the street lights of the road section where the road end is located, obtaining the path planning information and current positioning information sent by the vehicle end based on V2X communication.
[0066] The streetlight control information at the roadside in the embodiments of the present application may specifically include sensor-collected information and streetlight control configuration information. The sensor-collected information may be the ambient light intensity sensed by a light sensor deployed at the roadside, or the ambient light intensity identified by an image sensor deployed at the roadside using an image recognition algorithm. In real-world scenarios, light intensity varies in different environments, such as daytime or nighttime, sunny or cloudy, or rainy, and thus the requirements for streetlight lighting status also vary. Sensors can detect light intensity in different environments, providing a preliminary basis for streetlight control.
[0067] Streetlight control configuration information primarily refers to information such as the streetlight on / off status and streetlight intensity configured for each road section under different environments. For example, streetlights may be configured to be off during sunny days, or to have a higher intensity on cloudy days than on sunny days. Of course, the specific configuration of streetlight control information at the roadside can be flexibly configured by those skilled in the art based on actual needs and is not specifically defined here.
[0068] Because the streetlight control information at the roadside is related to the road section's environment, if it's a clear daytime, for example, the streetlight control information at the roadside can clearly determine not to turn on the streetlights on that road section. In this case, there's no actual need to further adjust the streetlight lighting status based on the vehicle-side V2X data. Based on this, embodiments of the present application can first determine whether to turn on the streetlights on the road section where the roadside terminal is located, and then perform subsequent operations if the streetlights on that road section are turned on.
[0069] In some embodiments of the present application, the path planning information includes the vehicle's driving route, and determining the target vehicle corresponding to the road section where the road end is located based on the path planning information includes: determining whether the vehicle's driving route passes through the road section where the road end is located; and if the vehicle's driving route passes through the road section where the road end is located, taking the vehicle as the target vehicle.
[0070] The path planning information of the embodiment of the present application may specifically include the vehicle's driving route. The vehicle's driving route can be generated through human-computer interaction on the vehicle side. The vehicle-computer system interacts with the user through human-computer interaction to obtain the starting and end point information input by the user, and then the path planning module automatically generates a planned driving route for the vehicle.
[0071] Since V2X communication sends its own V2X data to the outside world in a broadcast manner, all road ends within the V2X communication range of the vehicle will receive the vehicle's V2X data, but the road sections where these road ends are located are not all the sections that the vehicle actually wants to travel or pass through.
[0072] Based on this, the road terminal of the embodiment of the present application can determine whether the vehicle's route will pass through the road section where it is located based on the route information reported by the vehicle. If the vehicle's route will not pass through the road section where the road terminal is located, then it is obviously not necessary to use the relevant information of the vehicle as the basis for street light control. Conversely, if the vehicle's route will pass through the road section where the road terminal is located, which can include situations such as about to pass, currently passing, and just passing the road section, then these vehicles can be used as target vehicles in the road section where the road terminal is located and serve as the basis for subsequent street light control.
[0073] The path planning information reported by vehicles can provide a basis for the refined control of street lights and avoid the problem of wasted street light resources caused by the broadcast characteristics of V2X communication in existing solutions.
[0074] In some embodiments of the present application, controlling the street lamp lighting status of the road section where the road end is located based on the current positioning information of the target vehicle includes: determining the number of valid target vehicles corresponding to the road section where the road end is located based on the type of the target vehicle and the current positioning information of the target vehicle; and controlling the street lamp lighting status of the road section where the road end is located based on the current positioning information of the valid target vehicles and the number of valid target vehicles.
[0075] The "effective target vehicle" in the embodiment of the present application can be understood as a target vehicle that has a greater impact on the control of street lights on the road section where the road end is located, or it can be understood as a target vehicle that has a greater impact on the lighting requirements of the target vehicle due to the lighting status of the street lights on the road section where the road end is located.
[0076] The types of target vehicles may include, for example, vehicles that are about to enter the section where the road end is located, vehicles that have already entered the section where the road end is located, and vehicles that are leaving the section where the road end is located. Different types of target vehicles also affect the determination of valid target vehicles. Therefore, the embodiment of the present application can determine whether the target vehicle is a valid target vehicle corresponding to the section where the road end is located based on the type of target vehicle and the current positioning information, and further obtain the number of valid target vehicles corresponding to the section where the road end is located.
[0077] The number of valid target vehicles on the road section where the road end is located indicates the number of vehicles actually affected by the streetlight lighting status of that road section. The greater the number of valid target vehicles, the more vehicles affected by the streetlight lighting status, i.e., the more vehicles on that road section need streetlight lighting, and vice versa. Therefore, embodiments of the present application can fine-tune the streetlight lighting status of the road section where the road end is located based on the number of valid target vehicles and the current positioning information of these vehicles.
[0078] In some embodiments of the present application, controlling the street lamp lighting status of the road section where the road end is located based on the current positioning information of the valid target vehicle and the number of the valid target vehicles includes: determining the relative distribution position of the valid target vehicle and the road section where the road end is located based on the current positioning information of the valid target vehicle; determining the light intensity of the current road section based on the number of valid target vehicles and the correspondence between the number of vehicles and the light intensity of the road section; determining the light intensity of each street lamp in the current road section based on the relative distribution position of the valid target vehicle and the road section where the road end is located and the light intensity of the current road section.
[0079] Since the street light control method of the embodiment of the present application is mainly used in idle road scenarios, the number of valid target vehicles corresponding to the road section at the same time is relatively small. If all the street lights on the road section are turned on to illuminate or provide a strong light intensity, it will still cause a certain amount of resource waste. Therefore, the embodiment of the present application can, on the one hand, first determine the light intensity required for the entire road section based on the number of valid target vehicles corresponding to the current road section. On the other hand, it can also determine the distribution of the valid target vehicle on the road section based on its current position, so that the street lights that are closer to the valid target vehicle can be coordinated to provide lighting for the vehicle or enhance its light intensity.
[0080] That is, for the road end, the unified control of the street lights on the road section can be to control the switch status and light intensity of each street light separately, or to control the switch status and light intensity of multiple street lights at the same time.
[0081] like Figure 2 As shown, a schematic diagram of the street light control effect in an embodiment of the present application is provided, from which it can be seen that the roadside controller can determine the lighting control of the street lights on the road section according to the driving direction and distribution position of the vehicle (HV) on the road section. According to the principle of proximity, the street lights closest to the vehicle are preferentially called to provide lighting for it.
[0082] In addition, embodiments of the present application can establish in advance a correspondence between the number of valid target vehicles on a road section and the required street light illumination intensity. For example, when the number of valid target vehicles is 3, the corresponding street light illumination intensity is L1; when the number of valid target vehicles is 5, the corresponding street light illumination intensity is L2; when the number of valid target vehicles is 7, the corresponding street light illumination intensity is L3, and so on. The greater the number of valid target vehicles, the greater the street light illumination intensity. The above correspondence can be a linear relationship or a nonlinear relationship.
[0083] Of course, in order to further simplify the processing, it can also be determined by setting multiple quantity intervals. For example, when the number of valid target vehicles is within the first quantity interval, the street light intensity L1 is adopted; when the number of valid target vehicles is within the second quantity interval, the street light intensity L2 is adopted; when the number of valid target vehicles is within the third quantity interval, the street light intensity L3 is adopted, and so on.
[0084] It should be noted that the above embodiments are merely schematic descriptions. Those skilled in the art can flexibly configure how to determine the streetlight illumination intensity required for different numbers of valid target vehicles according to actual needs, and no specific limitation is made here.
[0085] In some embodiments of the present application, determining the number of valid target vehicles corresponding to the road section where the road end is located based on the type of the target vehicle and the current positioning information of the target vehicle includes: if the target vehicle is a vehicle that has entered the road section where the road end is located, directly using the target vehicle as the valid target vehicle corresponding to the road section where the road end is located; if the target vehicle is a vehicle that is about to enter the road section where the road end is located or a vehicle that is leaving the road section where the road end is located, determining whether the target vehicle is a valid target vehicle corresponding to the road section where the road end is located based on the current positioning information of the target vehicle.
[0086] When determining a valid target vehicle, the embodiment of the present application can adopt different strategies for different types of target vehicles. For example, if it is a target vehicle that has currently entered the road section, then it is obvious that the street light lighting status of this road section will affect the target vehicle, so it can be directly regarded as a valid target vehicle.
[0087] If the target vehicles are about to enter the road section where the road end is located or have already left the road section where the road end is located, since these target vehicles are not on the road section, compared with the target vehicles that have already entered the road section, these target vehicles will be less affected by the street light lighting status of the road section. Specifically, the current positioning information of these target vehicles can be combined to determine whether they need to be valid target vehicles for the road section.
[0088] In some embodiments of the present application, the current positioning information includes the current position, and determining whether the target vehicle is a valid target vehicle corresponding to the road section where the road end is located based on the current positioning information of the target vehicle includes: determining the distance between the target vehicle and the road section where the road end is located based on the current position of the target vehicle and the position information of the road section where the road end is located; and determining whether the target vehicle is a valid target vehicle corresponding to the road section where the road end is located based on the distance between the target vehicle and the road section where the road end is located.
[0089] For both types of target vehicles mentioned above, vehicles about to enter the road section where the road end is located and vehicles leaving the road section where the road end is located, when determining whether they should be considered valid target vehicles for that road section, the relative distance between the target vehicle and the road section can be calculated based on the current position reported by the target vehicle and the location information of the road section where the road end is located. The location information of each road section can be considered as known information. During the map construction process, their absolute positions in the world coordinate system have been calibrated, specifically including the starting and ending positions of the road section. For vehicles about to enter the road section where the road end is located, the relative distance between the target vehicle and the starting position of the road section can be calculated. For vehicles leaving the road section where the road end is located, the relative distance between the target vehicle and the ending position of the road section can be calculated.
[0090] The closer the relative distance between the current position of the target vehicle and the road section, the more likely it is to be affected by the street lighting status of the road section. Therefore, based on the size of the relative distance, it is possible to preliminarily judge whether the target vehicle needs to be regarded as a valid target vehicle for the road section. For example, if the relative distance is less than the preset distance threshold, the target vehicle is regarded as a valid target vehicle. Otherwise, it does not need to be regarded as a valid target vehicle.
[0091] In some embodiments of the present application, the current positioning information also includes the current driving speed, and determining whether the target vehicle is a valid target vehicle corresponding to the road section where the road end is located based on the current positioning information of the target vehicle includes: determining the time when the target vehicle arrives at / leaves the road section where the road end is located based on the distance between the target vehicle and the road section where the road end is located and the current driving speed of the target vehicle; and determining whether the target vehicle is a valid target vehicle corresponding to the road section where the road end is located based on the time when the target vehicle arrives at / leaves the road section where the road end is located.
[0092] Judging whether a target vehicle needs to be treated as a valid target vehicle based on the distance between the target vehicle and the current road section can achieve fine-tuning of street light control to a certain extent, but there may be some special circumstances. For example, for a vehicle about to enter the road section, the current distance between the target vehicle and the road section is relatively far, and it may not be necessary to judge it as a valid target vehicle directly based on the distance. However, the current driving speed of the target vehicle is relatively high, and based on the driving speed, it is estimated that the time for the vehicle to arrive at the road section is relatively short, that is, the vehicle will arrive at the road section soon. This means that the street lighting status of the road section is still likely to affect the target vehicle. Therefore, in order to achieve early coordination of street lighting and avoid the problem of untimely lighting, it is more appropriate to treat the target vehicle as a valid target vehicle at this time.
[0093] On the contrary, if the current distance between the target vehicle and the road section is relatively close, it can be directly judged as a valid target vehicle based on the distance. However, the current driving speed of the target vehicle is relatively low. Based on the driving speed, it is estimated that the target vehicle will take a long time to reach the road section, that is, the target vehicle will arrive at the road section after a long time. In this case, it can be considered that the street lighting status of the road section has little impact on the target vehicle. If the street lighting is coordinated for the target vehicle in advance too early, it will cause a certain degree of resource waste.
[0094] The above comparison of arrival time can also be achieved through a preset time threshold. For example, if the arrival time is less than the preset time threshold, the target vehicle can be regarded as a valid target vehicle. Otherwise, it does not need to be regarded as a valid target vehicle.
[0095] Of course, a lower limit constraint can also be added here. When the current distance between the target vehicle and the road section is less than this lower limit, it indicates that the distance between the target vehicle and the current road section is very close. In this case, the target vehicle's current speed can be disregarded and it can be directly regarded as a valid target vehicle. Therefore, in the above embodiment, using speed to further constrain the refined adjustment of street lighting can ensure the timely coordination of street lighting, avoid premature or late adjustment of street lighting, and improve street lighting utilization.
[0096] In like manner, for the vehicle that leaves the current section, because it is a process that leaves gradually, so the streetlight illumination state of current section is also the process that changes progressively on the impact of this target vehicle, for example, if the current distance between the target vehicle that has left and the road section is farther away, because is the situation that has left this road section, at this moment, can not consider the problem of driving speed, directly judge that it no longer needs to be used as effective target vehicle by the mode of distance distance.If the current distance between the target vehicle that has left and the road section is also closer, but the driving speed of target vehicle is very large, it can leave this road section long time quickly in a short time, so also can no longer be used as effective target vehicle.And if the current distance between the target vehicle that has left and the road section is also closer, but the driving speed of target vehicle is very little, it is longer that it leaves this road section time, therefore can continue to be used as effective target vehicle.
[0097] There is another special case that needs to be explained. When the target vehicle's speed is almost 0 for a period of time, it means that the target vehicle is likely to have entered a stopped state. At this time, even if the current distance between the target vehicle and the road section is still relatively close, it can no longer be regarded as a valid target vehicle.
[0098] It should be noted that the above-mentioned situations are merely exemplary descriptions of the embodiments of the present application in combination with specific application scenarios. Those skilled in the art can also flexibly adjust how to determine the effective target vehicle in combination with actual scenarios, which are not listed here one by one.
[0099] In order to facilitate the understanding of the various embodiments of this application, Figure 3 As shown, a schematic diagram of a street light control process in an embodiment of the present application is provided. The road end first determines whether the street light needs to be turned on based on its own street light control information. If it does not need to be turned on, the entire process is directly terminated. If the street light needs to be turned on, the path planning information and current positioning information sent by the vehicle end through V2X communication are further obtained. According to the path planning information, it is determined which vehicles' routes pass through the road section where the road end is located, and these vehicles are used as target vehicles for the road section. The street light lighting status of the road section is controlled according to the current positioning information of the target vehicles. Finally, it can also be determined based on the pre-set timeout whether the V2X data reported by the vehicle has not been received for a long time. If so, the street light lighting of the road section is turned off, thereby reducing the waste of street light resources.
[0100] This application is based on the communication characteristics of V2X communication technology. It uses the method of reporting path planning information and current positioning information to provide a basis for the refined control of street lights. It can also coordinate the roadside street light equipment in advance for its lighting based on the vehicle's own information reported by the vehicle. This not only reduces the waste of street lights in scenarios such as idle roads, but also uses existing equipment to achieve coordinated control of the vehicle and road sides, reducing human intervention and ensuring safe and efficient communication.
