Traffic control system based on universal ball net belt, track and vehicle supporting plate

Abstract

The invention discloses a traffic control system based on a universal ball net belt, a track and a vehicle supporting plate. The system transports vehicles through the vehicle supporting plate driven by the universal ball net belt, so that the vehicles can efficiently pass through the crossroad without traffic lights or overpasses. It is guaranteed that the system is coordinated, orderly, fast and safe through the fact that the automobile supporting disc is fixed to the track continuously arranged on the single side, and the left side and the right side are not connected. After each transportation task is completed, the vehicle supporting plate can return to the starting point from the lower portion of the rail to prepare next transportation. The design ensures smooth traffic, improves the safety and efficiency of the intersection, and reduces congestion and waiting time. The system provides a new method for optimizing urban traffic flow management, is an efficient solution, and aims to improve urban traffic conditions, reduce congestion and improve safety.

Description

Technical fields: This invention relates to the field of urban traffic management technology, and in particular to a method and device for enabling vehicles to pass safely and efficiently through intersections without waiting for traffic lights by using a universal ball bearing conveyor belt and a trolley tray. Background technology: With the acceleration of urbanization, urban traffic congestion has become increasingly serious. Traditional traffic control methods, such as traffic lights, can ensure traffic safety to a certain extent, but often cause severe traffic jams during peak hours. Alternatively, people generally don't want to wait at traffic lights. While building overpasses and roundabouts can alleviate some traffic pressure, they are costly and consume large amounts of land. Therefore, finding an economical and efficient urban transportation solution is particularly important.

[0002] Vehicle Entry: When a vehicle enters its designated lane, the omnidirectional ball-bearing conveyor belt transfers the vehicle to the pallet. The conveyor belt under the pallet then transports both the pallet and the vehicle to the intersection of the tracks. The pallet is then released, and the vehicle is thrown off due to inertia. At the intersection, the omnidirectional ball-bearing conveyor belt accurately transfers the vehicle to the next pallet. This process continues until the intersection is cleared. Vehicles are then promptly driven away. The order of vehicle transport on the pallets is as follows: vehicles traveling straight are transported first, followed by vehicles traveling horizontally, then vehicles turning left from the opposite lane, and finally vehicles turning left from the opposite lane. This cycle repeats. If a smart camera at the intersection detects an accident, the omnidirectional ball-bearing conveyor belt stops operating. Resuming operation requires assessment by traffic personnel. After the system stops, traffic can continue as directed by traffic lights. The above achieves the goal of allowing vehicles to pass through intersections without waiting for traffic lights, overpasses, or roundabouts. Note: The pallet is fixed to the track and is transported by a swivel ball-bearing conveyor belt. When the vehicle reaches the end of the track section at the intersection, it is transported back to the starting point of the track from below, ensuring the vehicle is fully under the pallet and ready to transport the next vehicle. Note that the left and right pallets on the track are not connected; they are continuous. The lane starts operating when the system detects four wheels on the pallet, indicating a vehicle is present. Otherwise, it does not operate. Attached image description:

[0011] This invention provides an intelligent traffic control system based on a universal ball bearing mesh belt and a trolley tray. By laying a universal ball bearing mesh belt at an intersection and combining it with a trolley tray and rails, vehicles can move automatically in a predetermined sequence, thus allowing them to pass through the intersection quickly, safely, and smoothly without waiting for traffic lights. Detailed implementation method:

[0012] 1. System Composition:

[0013] Universal ball bearing conveyor belt: laid on the ground of intersections and lanes to support the movement of pallets or cars.

[0014] Tray: Fixed to the rails, used to carry and secure vehicles, which are transported by an omnidirectional ball-bearing conveyor belt below. The system operates according to a fixed sequence of passing vehicles.

[0015] 2. Working principle:

[0016] Vehicle entry: When a vehicle enters the corresponding lane, the omnidirectional ball bearing conveyor belt will transfer the vehicle to the pallet when the system reaches this track.

[0017] Tray securing: Secure the vehicle once it arrives at the designated location.

[0018] Sequential transport: The central controller controls the transport of pallets according to a predetermined sequence, transporting vehicles sequentially through the intersection. The specific sequence is as follows:

[0019] 1. Vertical Straight Movement: First, transport vehicles that move straight in the vertical direction.

[0020] 2. Lateral Straight-Ahead: Then, the vehicle will be transported in a straight-ahead direction in the lateral direction.

[0021] 3. Vertical left turn: Then transport vehicles turning left from the opposite lane in the vertical direction.

[0022] 4. Lateral left turn: Finally, it delivers vehicles turning left from the opposite lane in the lateral direction.

[0023] Pallet transport: The pallet is transported to the track junction point by the omnidirectional ball bearing belt below. After reaching the end, the fixing is released, and the vehicle is thrown off the pallet by inertia and accurately transferred to the next track pallet by the omnidirectional ball bearing belt at the junction point.

[0024] Tray return: After the vehicle body is completely off the tray, it returns to the starting point of the track below the track intersection point to wait for the transport of the next vehicle.

[0025] Cyclic operation: After completing one round of delivery, the system returns to its initial state and prepares to receive the next vehicle.

[0026] Each lane carries only one vehicle at a time through the intersection. After passing through, the system cycles through the intersection. When the vehicle returns to the same lane, the omnidirectional ball bearing conveyor belt carries the parked vehicle into the pallet, starting the second transfer.

[0027] 3. Security Mechanism:

[0028] Smart cameras: Installed above intersections, they monitor traffic conditions in real time. Upon detecting an accident or other anomaly, the smart cameras immediately notify the central controller.

[0029] Emergency Stop: Upon receiving an abnormal signal, the central controller will immediately stop the operation of all omnidirectional ball bearing conveyors and trolley trays, and activate the traffic personnel intervention mode to ensure on-site safety.

[0030] advantage:

[0031] Improved efficiency: Eliminating waiting time caused by traditional traffic lights improves the overall efficiency of the transportation system, ensuring speed, safety, and order.

[0032] Cost-effective: Compared with building large-scale infrastructure such as overpasses, the implementation cost of this invention is lower and the footprint is smaller.
