Description

Technical Field

[0001] The present invention belongs to the technical field of tunnel construction, and more specifically, relates to an intelligent transportation system for tunnel transportation. Background Art

[0002] With the vigorous development of my country's infrastructure construction, various industries such as highways, railways, water conservancy, and urban rail transit include a large number of tunnel construction, and tunnel construction cannot be separated from safe and efficient transportation. At present, the transportation of tunnel construction is mainly based on rail locomotives, and there are also some other transportation equipment such as rubber-wheeled locomotives. In the construction of long tunnels, as the transportation distance increases, the number of transportation vehicles increases simultaneously. There are many transportation vehicles running in the tunnel at the same time, and the running speed is fast. Traditional tunnel construction transportation mainly relies on dispatchers to organize transportation, and cannot monitor the transportation vehicles in real time to understand the location of the vehicles in the tunnel; when there are many vehicles running in the tunnel, the safety of meeting and passing is low, and the risk is relatively high. When there is a possibility of meeting and passing, the driver usually waits in the set area, and the waiting time is uncontrollable, which wastes a lot of time; when the construction area needs materials, the dispatching area is notified by phone, and the preparation items are missed and the preparation quantity is inaccurate through paper and pen records or human brain memory; when the vehicle in the tunnel breaks down or falls off the road, the tunnel is long and emergency assistance cannot be provided in time.

[0003] In the face of the above problems, transportation guarantee issues such as safe meeting and passing of vehicles in tunnel construction, monitoring of transportation vehicles, and timely and complete transportation of construction materials to the construction area need to be urgently addressed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent transportation system for tunnel transportation, which provides reliable guarantee for safe meeting and passing of vehicles in tunnel construction transportation, monitoring of transportation vehicles and timely and complete transportation of construction materials to the construction area.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A tunnel transportation intelligent transportation system comprises:

[0007] The vehicle management subsystem numbers construction transport vehicles, freely groups auxiliary vehicles, and installs on-board chips on transport vehicles to bind transport vehicle information and driver information through the on-board chips;

[0008] The monitoring subsystem divides the tunnel under construction into three areas: the dispatching area, the transportation area, and the construction area. Display screens are installed in the dispatching area and the construction area. Chip sensors are installed between the dispatching area and the transportation area, and between the transportation area and the construction area. The chip sensors identify the on-board chips and display the area where the transport vehicle is located on the display screens in the dispatching area and the construction area. The vehicle information, driver information, and material information transported by the vehicle can also be viewed. In tunnels with long transportation distances, meeting points are set in the transportation area. The distance between each two meeting points is 2km, which can also be adjusted according to the actual construction situation. Card readers are installed at the meeting points to identify the vehicle numbers and display the location of the transport vehicle in the transportation area on the display screen.

[0009] The driving and passing subsystem, when the tunnel can accommodate two or more vehicles passing in parallel, and the transport vehicle is a rail transport vehicle, an indicator light is set at the meeting point. The number of indicator lights in each group is the number of vehicles that can pass in parallel in the transport area. The indicator lights are set in both directions. The indicator lights are set in a conspicuous position and are easy for the transport vehicle driver to observe. They display red or green. The track occupied by the vehicle is read through the card reader, and the occupied track is indicated to the oncoming vehicle entering the next meeting point. When multiple vehicles enter adjacent meeting points, they enter the designated channel through the walkie-talkie carried by the vehicle driver to communicate with each other during driving; when the tunnel can only accommodate single vehicle operation, a single group of two-way indicator lights is set at the meeting point. After the vehicle enters the meeting point, the indicator light of the oncoming vehicle at the next meeting point will display red, and the vehicle needs to enter the meeting point to wait. The two vehicles continue to move forward after passing each other at the meeting point;

[0010] The material subsystem is mainly managed and used by the dispatcher in the dispatching area and the dispatcher in the construction area. The dispatcher in the construction area enters the required materials into the system, and the dispatcher in the dispatching area arranges the loading of materials according to the needs of the construction area. When the transport vehicle leaves the transport area and enters the dispatching area, the dispatcher in the dispatching area takes over the locomotive and guides the vehicle to the designated location for loading and unloading. When the transport vehicle leaves the transport area and enters the construction area, the dispatcher in the construction area takes over the locomotive and guides the vehicle to the designated location for loading and unloading.

[0011] Preferably, the vehicle management subsystem can bind the information of multiple drivers and select the driver on duty according to the duty situation.

[0012] Preferably, when the transport vehicle is a rail locomotive or a rubber-tyred locomotive, the traction locomotive is numbered; and the auxiliary vehicles such as flatbed trucks, cement tank trucks, bean gravel trucks, and segment trucks are freely grouped.

[0013] Preferably, when a transport vehicle encounters a problem during transportation, such as a vehicle breakdown or a locomotive falling off a road light, when the vehicle is in a dispatching area or a construction area, the area where the vehicle is located will be responsible for assisting in handling the problem. When the vehicle is in a transport area with a short transport distance, the dispatching area will handle the problem. When the vehicle is in a transport area with a long transport distance, the location of the vehicle will be displayed based on the monitoring subsystem, and the dispatching area or construction area that is close will be responsible for assisting in handling the problem.

[0014] Preferably, when the mode of transport is rail locomotive, a turnout is installed at the meeting point, and when the mode of transport is trackless vehicle, a shelter is set at the meeting point.

[0015] Preferably, vehicles traveling in the same direction can pass each other by having the driver carry a walkie-talkie and enter the nearby meeting point to pass or overtake.

[0016] The beneficial effects of adopting the above technical solution are:

[0017] First, the vehicle management subsystem uses the information system to number the transport vehicles and can freely marshal trains. Through monitoring, the dispatcher can understand the vehicle information, marshalling information, driver information and other information in real time, which is conducive to the dispatching work arrangement of the dispatching area;

[0018] Second, the monitoring subsystem monitors the transport vehicles and tracks the area and location of the vehicles in real time, which facilitates the dispatcher to manage the vehicles and provides a basis for the construction work arrangement in the construction area.

[0019] Third, the passing vehicle subsystem intelligently directs traffic in the tunnel by installing chip sensors and setting indicator lights at the meeting points. Vehicles complete the passing of oncoming vehicles according to the indicator lights, providing guarantee for safe driving in the tunnel.

[0020] Fourth, the material subsystem realizes the information management of material request in the construction area and material preparation in the dispatching area, reducing human factors and reducing the problems of missing material preparation items and inaccurate material preparation quantities in paper and pen records or human memory;

[0021] Fifth, when a moving vehicle breaks down, derails, or encounters other problems, monitoring and zoning responsibilities can facilitate rapid rescue assistance, quickly resolve transport vehicle problems, and reduce liability disputes. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] like Figure 1-3 As shown, the overall system is divided into four subsystems: vehicle management subsystem, monitoring subsystem, driving error subsystem, and material subsystem.

[0028] Among them, the vehicle management subsystem numbers the construction transport vehicles. If the transport vehicle is a rail locomotive or a rubber-wheeled locomotive, the traction locomotive is numbered, and the auxiliary vehicles (flatbed trucks, cement tankers, bean gravel trucks, segment trucks, etc.) are freely grouped. The transport vehicle is equipped with an on-board chip, and the transport vehicle information and driver information are bound through the on-board chip (multiple drivers can be bound, and the on-duty driver is selected based on the duty situation).

[0029] The monitoring subsystem divides the tunnel under construction into three areas: dispatching area 1, transport area 2, and construction area 4. Display screens are set in dispatching area 1 and construction area 4, and chip sensors 7 are set between adjacent areas (dispatching area 1 and transport area 2, transport area 2 and construction area 4). The sensor recognizes the on-board chip and displays the area where the vehicle is located on the display screens in dispatching area 1 and construction area 4. The vehicle information, driver information and material information transported by the vehicle can also be viewed.

[0030] For tunnels with longer transport distances, a meeting point 3 is set up in transport area 2 (the distance is about 2 km, which can be adjusted according to the actual construction situation). A card reader is installed at the meeting point 3 to identify the vehicle number and display the position of the transport vehicle in transport area 2 (the interval between two adjacent meeting points 3) on the display.

[0031] When the mode of transport is rail locomotive, a four-track three-line turnout 5 for rail transport vehicles is installed at the meeting point 3; when the mode of transport is trackless vehicles, a shelter is set at the meeting point 3.

[0032] When the tunnel section is large (about 8m or more) and there is ample space for vehicles to pass in parallel, and the transport vehicle is a rail transport vehicle, an indicator light 6 is set at the meeting point 3. The number of indicator lights 6 in each group is the number of vehicles that can pass in parallel in the transport area 2 (usually 2 or 3). The indicator lights 6 are set in both directions. The indicator lights 6 are set in a conspicuous position and are easy for the transport vehicle driver to observe. They display red or green. The track occupied by the vehicle is read by the card reader, and the occupied track is indicated to the oncoming vehicle entering the next meeting point 3 (the occupied track is displayed in red, and the oncoming vehicle is prohibited from driving. The unoccupied track is displayed in green, and the oncoming vehicle can pass). When multiple vehicles enter the adjacent meeting point 3, they enter the designated channel through the walkie-talkie carried by the vehicle driver to communicate about driving.

[0033] When the tunnel cross-section is small and only meets the needs of single-vehicle operation, a single set of two-way indicator lights 6 is set at the meeting point 3. After the vehicle enters the meeting point 3, the indicator light 6 of the oncoming vehicle at the next meeting point 3 shows red, and the vehicle needs to enter the meeting point 3 to wait. After the two vehicles pass each other at the meeting point 3, they continue to move forward.

[0034] Vehicles traveling in the same direction can pass each other by using the intercom carried by the driver, entering the nearby meeting point 3, and passing or overtaking.

[0035] The material subsystem is mainly managed and used by the dispatcher of Dispatching Area 1 and the dispatcher of Construction Area 4. The dispatcher of Construction Area 4 enters the required materials into the system, and the dispatcher of Dispatching Area 1 arranges the loading of materials according to the needs of Construction Area 4.

[0036] When the transport vehicle leaves transport area 2 and enters dispatch area 1, the dispatcher of dispatch area 1 takes over the locomotive and guides the vehicle to the designated location for loading and unloading. When the transport vehicle leaves transport area 2 and enters construction area 4, the dispatcher of construction area 4 takes over the locomotive and guides the vehicle to the designated location for loading and unloading.

[0037] When a transport vehicle encounters a problem during transportation (vehicle failure, locomotive derailment), when the vehicle is in dispatching area 1 or construction area 4, the area where the vehicle is located will be responsible for assisting in handling the problem. When the vehicle is in transport area 2 with a shorter transportation distance, dispatching area 1 will handle it. When the vehicle is in transport area 2 with a longer transportation distance, the monitoring subsystem will display the vehicle's location, and the area closest to it (dispatching area 1 or construction area 4) will be responsible for assisting in handling the problem.

[0038] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
