Description

Technical Field

[0001] This invention relates to a rapidly deployable traffic signal light based on unmanned aerial vehicles (UAVs), belonging to the field of traffic signal light technology. Background Technology

[0002] Traffic lights are core facilities for maintaining road traffic order and ensuring traffic safety; their stable operation directly affects traffic flow and safety. However, in actual use, traffic lights are prone to malfunction due to various factors such as equipment failure, severe weather, and power outages, leading to traffic chaos and safety hazards.

[0003] Currently, there are significant shortcomings in the emergency response methods for traffic signal malfunctions: manual on-site repairs are time-consuming, especially in remote or busy sections, requiring traffic police to direct traffic on-site, which consumes a large amount of police resources; portable emergency traffic lights require manual transportation and additional power supply, resulting in low deployment efficiency and the inability to synchronize with surrounding traffic lights, which can easily lead to traffic conflicts.

[0004] Drone technology has been widely used in the field of intelligent transportation. Its advantages of rapid response and flexibility have provided support for traffic emergency response. Tethered drone technology has further solved the problems of short battery life and unstable signal transmission.

[0005] However, existing drones have not achieved integrated operation with traffic lights and cannot be quickly deployed as emergency traffic lights; some integrated solutions also have problems such as unstable power supply, signal delay, and inability to synchronize, making it difficult to meet the emergency needs of intersections with malfunctions. Summary of the Invention

[0006] The purpose of this invention is to provide a rapidly deployable traffic light based on unmanned aerial vehicles (UAVs) to solve the aforementioned technical problems.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A rapid deployment traffic light based on a drone includes a drone and a traffic light, wherein the traffic light is fixedly mounted on the drone; the traffic light is powered by the drone; the traffic light communicates with the backend via the drone's communication module; a camera is mounted on the drone; the traffic light can be deployed on the ground or on a traffic light pole.

[0008] A further improvement to the technical solution of the present invention is that the traffic lights are multi-directional indicators; the traffic lights are deployed at the center of the intersection ground.

[0009] A further improvement to the technical solution of the present invention is that the signal light is fixedly installed on the upper surface of the drone.

[0010] A further improvement to the technical solution of the present invention is that the signal light is fixedly installed on the lower end face of the drone; the signal light has a support.

[0011] A further improvement to the technical solution of the present invention is as follows: the traffic lights are in a single-direction indication mode; the traffic lights are deployed on traffic light poles, and traffic lights are respectively installed on the traffic light poles in each direction at the intersection, and the traffic lights in each direction are networked and linked through the communication module of the drone.

[0012] A further improvement to the technical solution of the present invention is as follows: the signal light is fixed on the upper surface of the drone, a bracket is provided at the lower end of the drone, and a clamp for fixing the signal light pole is provided on the bracket.

[0013] A further improvement to the technical solution of the present invention is as follows: the signal light is fixed on the lower surface of the drone, a bracket is provided at the lower end of the signal light, and a clamp for fixing it on the signal light pole is provided on the bracket.

[0014] A further improvement to the technical solution of the present invention is as follows: a thin-film photovoltaic panel is attached to the surface of the drone, and the drone battery is a solar rechargeable battery; the thin-film photovoltaic panel is electrically connected to the solar rechargeable battery.

[0015] Due to the adoption of the above technical solution, the technical effects achieved by this invention are as follows: This technical solution is a rapidly deployable traffic light system based on drones, combining emergency traffic lights with drones. The drones not only serve as transportation tools but also play a significant role in the operation of the emergency traffic lights. Drones can power the traffic lights. They can also act as communication relays, enabling long-distance wireless communication between the traffic lights and the control center via their wireless communication modules, thus facilitating traffic control. Simultaneously, drones can also function as communication base stations, enabling network connectivity of multiple traffic lights at the same intersection, thereby achieving effective traffic command and control and ensuring orderly traffic flow.

[0016] This technical solution's traffic light requires no additional power cable; the drone can power it via a very short internal power cable. Because it utilizes the drone's wireless communication module, no additional signal cables are needed, making the traffic light easier and faster to deploy.

[0017] This technical solution is a traffic light system based on drones for rapid deployment. The traffic lights are combined with drones and deployed at multiple sites, enabling rapid deployment when needed and reducing the adverse effects of traffic light damage on traffic.

[0018] This technical solution can be deployed either on the ground or on traffic light poles, depending on the type of intersection, making it highly adaptable.

[0019] In this technical solution, a thin-film photovoltaic panel is installed on the surface of the drone, which can convert solar energy into electrical energy. The drone's battery is a rechargeable battery, thereby achieving a long-term stable power supply and a relatively long-term stable deployment of the signal lights. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] This invention is a rapidly deployable traffic signal light based on drones, which deeply integrates traditional emergency traffic light equipment with drones to achieve rapid deployment.

[0025] This technical solution includes a drone and a signal light. The signal light is fixedly mounted on the drone, and its power cord is electrically connected to the drone's power supply; the signal light is powered by the drone. The signal light does not need to carry its own power source.

[0026] Traffic lights need to communicate with the traffic control system's backend, and this communication connection is achieved using the communication module of a drone. The traffic lights first establish a communication connection with the drone, and then the drone's communication module establishes a communication connection with the traffic control system's backend, thus enabling the traffic lights to communicate with the backend as well.

[0027] Cameras are installed on drones to identify locations during flight; this is a component that drones come with.

[0028] The traffic light can be deployed on the ground or on a traffic light pole.

[0029] If the traffic lights are deployed on the ground, they are fixed to the underside of the drone and have a support at the bottom. The drone transports the traffic lights to the designated location and then descends with them, the support providing support for both the traffic lights and the drone. For ground-deployed traffic lights, the lights need to be placed in the center of the intersection and have a multi-directional indicator structure. For example, at a four-way intersection, four directional indicator lights need to be integrated. After deployment, the four directional lights correspond to the four directions of the intersection. At a three-way intersection, three directional indicator lights can be integrated, each corresponding to one of the three directions. More specifically, it could be a single-light-multiple-color mode for one direction, such as... Figure 3 As shown. It could also be a multi-light mode in one direction, such as... Figure 4 As shown.

[0030] If the traffic lights are deployed on light poles, they operate in a unidirectional mode, meaning only one set of traffic lights corresponds to an intersection in a specific direction. In this mode, the traffic lights can be fixed to the upper surface of the drone, but it's crucial that the lights don't interfere with the drone's wing operation. A bracket is installed below the drone, with grippers on the bracket to secure the drone to the traffic light pole, effectively fixing the traffic light to the pole. During the drone's descent with the traffic light, the grippers contact the pole and clamp onto it. Multiple grippers are needed to ensure overall stability. Alternatively, the traffic lights can be fixed to the lower surface of the drone, with a bracket at the lower end of the light light and grippers on the bracket for secure mounting to the traffic light pole. This mode requires multiple sets of traffic lights, deployed on the respective traffic light poles at each intersection. The number of traffic light sets is determined by the number of directions at the intersection; three sets are used for a three-way intersection, and four sets for a square intersection.

[0031] The above method uses grippers to mount traffic lights onto traffic light poles. Other methods can also be used. For example, mounting holes can be pre-drilled on the traffic light pole, and a mounting rod can be installed on the traffic light. The insertion and removal of the traffic light is also easy. Alternatively, an electromagnetic chuck can be used, but the magnetic attraction must be reliable. The presence or absence of the magnetism is controlled by a power switch.

[0032] When the traffic lights are in a one-way indication mode, the traffic lights in each direction need to be networked and linked through the communication module of the drone to achieve orderly control of road traffic.

[0033] The traffic light is primarily powered by a large transport drone whose battery provides emergency power. To extend the power supply time, the drone is configured to operate in a solar-powered mode. Specifically, thin-film photovoltaic panels are attached to the drone's surface. These panels convert solar energy into electricity, and the drone's battery is a solar-powered rechargeable battery. By electrically connecting the thin-film photovoltaic panels to the solar-powered battery, solar energy can be converted into electrical energy and stored in the drone's battery.

[0034] In this technical solution, the drone acts as a communication relay to communicate with the backend system, and can also serve as a communication base station to network multiple traffic lights at the same intersection, all using wireless communication. Because drones are used, no additional wiring is required. Traffic police can deploy and control the drones from the rear.

[0035] This technical solution utilizes drones for rapid deployment of traffic lights. The traffic lights are integrated with drones and deployed at multiple locations. If a traffic light malfunctions at an intersection within a certain area, it can be quickly deployed and arrive at the scene via drone, typically within approximately 10 minutes. The traffic light is powered by the drone's battery and communicates with the backend system using the drone's communication module, enabling efficient and precise control.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
