[0048] The present invention discloses a truss-straddle type intelligent PRT transportation system, which mainly includes the following features: 1. The truss-type track system mainly refers to the track body, that is, the unit constituting the track system, which adopts a truss structure; 2. The rail car adopts an intelligent rail car, and further, a straddle-type intelligent rail car; 3. A relatively complete automatic driving control system is set up, and the rail car can realize automatic control operation and automatic marshaling; 4. By adopting a fixed turnout structure, a structurally stable and complex rail system (road network) can be constructed, and an offline platform structure can be constructed.

[0049] Specifically, the truss straddle type intelligent PRT transportation system provided by the present invention includes:

[0050] 1. Track system

[0051] In the present invention, the track system is an overhead track system, which includes a track body and columns 1 . The track body is spliced ​​and assembled into a road network, and the road network is supported overhead by the columns 1 .

[0052] The column 1 adopts a circular tube structure, and the pipe sections are connected by flange structures. A track docking section for docking with the track body is arranged on the top of the column 1, and a road network is formed by docking with the track body through the track docking section.

[0053] The track is composed of multiple track bodies, and the structure of the track body is as follows: there are two track bodies, which extend in parallel, and diagonal braces 5a and cross beams 5b are arranged on the track bodies. A bottom main beam 4 is arranged below the track bodies, and the extension direction of the bottom main beam 4 is parallel to the extension direction of the track bodies.

[0054] Specifically, two diagonal braces 5a are provided, and the two diagonal braces 5a are provided in the same vertical plane for providing inclined upward supporting force. The crossbeam 5b and the diagonal braces 5a are provided in the same vertical plane. The crossbeam 5b is fixedly connected to the two diagonal braces 5a at the same time for maintaining the relative posture of the two diagonal braces 5a. The diagonal braces 5a and the crossbeam 5b form a tripod.

[0055] In the extension direction perpendicular to the track body, the cross-sections of the two track bodies and the bottom main beam 4 constitute the three vertices of an inverted triangle, the diagonal brace 5a constitute the two bases of the inverted triangle, and the cross beam 5b constitutes a top side of the inverted triangle. In this way, the track body, the bottom main beam 4, the diagonal brace 5a and the cross beam 5b can form a triangular tripod structure.

[0056] Specifically, a pair of wheel treads 2 with normal lines pointing upward are provided on the track body, which are used to provide upward bearing force for the wheels of the rail vehicle; a pair of steering surfaces with normal lines pointing outward are also provided on the track body, and their span is greater than the width of the pair of wheel treads 2, which are used to provide lateral steering force for the steering wheels of the rail vehicle; a pair of guide surfaces with normal lines pointing inward are also provided on the track body, and their span is less than the width of the pair of guide surfaces, which are used to provide lateral guiding force for the guide wheels of the rail vehicle.

[0057] The track body can be further divided into a docking section, which includes a track docking section bottom beam. The track docking section bottom beam is a circular tube structure. Two track docking section bottom beams are provided. The two track docking section bottom beams are symmetrically distributed on both sides of the column 1 near its (column 1) top. A support rod is provided between the track docking section bottom beam and the column 1. The track docking section bottom beam, the support rod and the column 1 can form a triangular structure, thereby improving the stability and reliability of the track docking section on the column 1. Along the length direction of the track docking section bottom beam, a track docking section tripod (composed of two diagonal braces 5a and a crossbeam 5b) is evenly spaced on the top surface of the track docking section bottom beam. The track docking section tripod is an isosceles triangle. The top corner of the track docking section tripod is arranged downward and fixedly connected to the track docking section bottom beam. The two bottom corners of the track docking section tripod are arranged upward for installing the wheel tread 2 and the guide rail 3. In the present invention, the column 1 and the track docking section arranged on the column 1 are both made of metal materials (preferably steel), and the connections between the parts are fixed by welding. For example, the tripod of the track docking section and the bottom beam of the track docking section are welded.

[0058] The track body is a truss structure. Specifically, the track body includes a bottom main beam 4 and a tripod 5. The bottom main beam 4 is a circular tube structure. The tripod 5 includes three square tubes (two diagonal braces 5a and a cross beam 5b). The three square tubes form an isosceles triangle tripod 5. The plane where the tripod 5 is located is perpendicular to the axis of the bottom main beam 4 in the length direction, that is, when the bottom main beam 4 is set horizontally, the tripod 5 is in a vertical setting state. The bottom angle of the tripod 5 (equivalent to the vertex angle of the isosceles triangle) is fixedly connected to the bottom main beam 4 (the connection method is preferably welding), and the wheel tread 2 is fixedly set on the two vertex angles of the tripod 5 (equivalent to the two bottom angles of the isosceles triangle), and the axis of the wheel tread 2 in the length direction is parallel to the axis of the bottom main beam 4 in the length direction.

[0059] In the present invention, the normal of the wheel tread 2 is vertically upward, the wheel tread 2 is arranged on the rail body, the wheel tread 2 is a plane, and the wheel tread 2 contacts the wheels of the rail vehicle to provide an upward support force for the wheels of the rail vehicle. Specifically, the wheel tread 2 is a metal flat plate structure, and its width is greater than the wheel width of the intelligent rail vehicle wheel 6. The wheel tread 2 is arranged on the top beam of the tripod (equal to the base of the isosceles triangle) and close to the two vertex positions of the tripod 5.

[0060] In the present invention, the bottom main beam 4, the tripod 5 and the wheel tread 2 are fixedly connected by welding, thereby forming a truss-type track body.

[0061] When the rail bodies are butted together, or when the rail bodies are butted together with the rail butting sections, the bottom main beams 4 or the bottom main beams 4 and the bottom beams of the rail butting sections are butted together with flange structures. In addition, other forms of connection structures can be provided on the rail bodies to improve the structural strength of the rail system without affecting the operation of the wheels 6, guide wheels 7 and steering wheels 8 of the intelligent rail vehicle.

[0062] The present invention also provides a steering surface and a guide surface on the track body, wherein the normal of the steering surface is horizontally outward, the steering surfaces are provided on both sides of the track body, the steering surfaces are in contact with the steering wheels of the rail vehicle, and are used to provide a horizontal outward steering force to the steering wheels; the normal of the guide surface is horizontally inward, the guide surfaces are provided on both sides of the track body and are located on the inner sides of the two steering surfaces, the guide surfaces are in contact with the guide wheels of the rail vehicle, and are used to provide a horizontal inward guiding force to the guide wheels. In a specific embodiment of the present invention, the steering surface and the guide surface are structures on the same component (i.e., the guide rail 3), and the guide rail is a groove-shaped structural component, the inner side surface of which is the guide surface, and the outer side surface of which is the steering surface. The steering surface and the guide surface are both vertical planes.

[0063] The present invention provides a wheel tread 2 and a guide rail 3 on the track body (including the track docking section). As can be seen from the above, the wheel tread 2 is a rectangular plate structure, the width of the wheel tread 2 is slightly larger than the wheel width of the wheel 6 on the intelligent rail vehicle, and the wheel treads 2 are grouped in two, and the wheel treads 2 of the same group are parallel and spaced apart, which are used to support the wheels 6 on both sides of the intelligent rail vehicle. The guide rail 3 adopts a U-shaped steel structure, the outer side of the guide rail 3 is a smooth plane structure, and the inner side of the guide rail 3 is a concave groove structure. After multiple track bodies are assembled together, the wheel tread 2 can form a smooth surface, and the guide rails 3 can also form a through groove structure and a smooth outer side surface, so as to ensure the stability of the intelligent rail vehicle during operation (no collision occurs when passing through two guide rails 3 or wheel treads 2).

[0064] Generally, the track system (or road network) includes a straight section, a turning section and a turnout structure. The construction of the straight section and the turning section is relatively simple and will not be described in detail here. As for the turnout structure, the present invention adopts a fixed turnout structure. Specifically, two track bodies intersect to form a fixed turnout. In the two track bodies constituting the fixed turnout, the wheel treads 2 are in the same plane. In the two track bodies constituting the fixed turnout, the guide rails 3 arranged on the inner side of the track bodies are connected through the curved rails 10. In the fixed turnout structure, the structures of the bottom main beam 4 and the tripod 5 remain unchanged. The difference from the general track main structure is that the main part of the fixed turnout structure is formed by the bottom main beam 4 and the tripod 5, and crossed straight-running wheel treads and turning wheel treads are arranged on the main part of the fixed turnout structure. In the fixed turnout structure, the outer guide rail 3 is a continuous structure, and the inner guide rail 3 is a disconnected structure. The inner guide rail is connected through a curved rail 10. The curved rail 10 is a U-shaped structure, and the outer side of the curved rail 10 is provided with a groove. When the intelligent rail vehicle passes through the fixed turnout structure, whether it is going straight or turning, the guide wheel 7 on the intelligent rail vehicle can be smoothly introduced into the inner guide rail 3 through the curved rail 10.

[0065] Of the two track bodies constituting the fixed turnout, one is located on the track trunk road for direct passage of the straddle-type intelligent rail vehicle, and the other forms a platform bypass for connecting the offline platform. The present invention is provided with a fixed turnout structure, which can separate a branch road from the trunk road, so that a complex road network can be formed and the offline platform can be connected.

[0066] In the present invention, the entire track is suspended by the column 1, the truss structure reduces the deformation of the track and greatly reduces the amount of steel used, the wheel tread 2 provides a contact surface for the vehicle, and the guide rail 3 provides a steering guide for the vehicle. Specifically, the axis of the column 1 is vertically upward, the top of the column 1 contacts the bottom surface of the bottom main beam 4, the axis of the column 1 is perpendicular to the axis of the bottom main beam 4, and the column 1 is used to provide support force for the bottom main beam 4.

[0067] The present invention adopts an overhead track structure, and the main body of the track is erected in the air through the column 1 to achieve independent right of way. When the vehicle is running, it is not disturbed by other people and vehicles. After eliminating the uncertain factors outside the system, the safety of rail vehicle operation is greatly improved, and the fail-safe principle can be realized; after the track is overhead, the track system does not affect the traffic of people and vehicles on the ground. The platform design of the present invention is different from that of the subway. It adopts an offline platform form. The platform is set outside the operating line (main road). The vehicles stopped on the platform do not affect other vehicles running on the main line, which greatly improves the operational flexibility. Passengers can go directly when riding. The direct way of the intelligent rail vehicle passing through the station without entering the station greatly improves the vehicle operation speed and efficiency. The present invention adopts a fixed turnout instead of a movable turnout like a railway or subway. The fixed turnout has a simple structure, no signal equipment is required on the trackside, and no microcomputer interlocking is required, which greatly improves safety. Since the track has only a fixed structure and no electric control actuator, a lot of costs such as track cable installation and testing are also saved.

[0068] 2. Straddle-type intelligent rail vehicle

[0069] The truss straddle type intelligent PRT transportation rail vehicle provided by the present invention is used for traveling on the truss straddle type intelligent PRT transportation track. The specific structure of the truss straddle type intelligent PRT transportation rail vehicle is as follows, including: a vehicle chassis 9; wheels, which are arranged in pairs on the vehicle chassis 9, and the wheels can roll on a pair of wheel treads of the track; steering wheels 8, which are arranged in pairs on the vehicle chassis 9, and the span is greater than the width of the paired wheels. In the steering state of the rail vehicle, at least one steering wheel 8 in each pair of steering wheels 8 rolls on the steering surface of the track, and its rotation axis is perpendicular to the rotation axis of the wheel, which is used to transfer the lateral steering force provided by the steering surface to the rail vehicle; guide wheels 7, which are arranged in pairs on the vehicle chassis 9, and the span is less than the width of the paired steering wheels 8, and the rotation axis is perpendicular to the rotation axis of the wheel, which is used to transfer the lateral steering force provided by the guide surface to the rail vehicle.

[0070] In the present invention, the intelligent rail vehicle adopts a straddle-type rail vehicle structure. The straddle-type intelligent rail vehicle can walk on the wheel tread 2. The straddle-type intelligent rail vehicle can travel automatically and can be automatically marshaled.

[0071] The present invention adopts a straddle-type vehicle. Compared with a suspended vehicle, the vehicle body is installed below the wheel tread 2, which will interfere with the fixed turnout at the turnout, affecting the turnout design. The body of the straddle-type vehicle is above the wheel tread 2, and there is no interference between the vehicle and the track at the fixed turnout. The turnout design is simple, the track is continuous, the vehicle travels at a high speed, and it is safe and has no jamming.

[0072] The present invention uses a small carriage for 2 to 4 people, rather than a large carriage for hundreds of people on railways and subways. Large carriages can carry a large number of passengers and have high operating efficiency, but the passenger experience is poor. Different passengers have different destinations. Using large carriages will result in too many stops and slow operation. Using small carriages can achieve point-to-point transportation and personal transportation under public transportation, with a good riding experience and high travel efficiency.

[0073] After using a small carriage, the present invention uses dynamic marshaling in control. When the traffic volume is large, the front and rear carriages are automatically connected through a coupler and travel in a marshaling manner, which greatly reduces the distance between carriages and increases the traffic volume.

[0074] Specifically, in the present invention, the straddle-type intelligent rail vehicle includes a vehicle chassis 9, wheels 6, a wheel power system, guide wheels 7, steering wheels 8 and a steering wheel control device 11.

[0075] Specifically, the wheel 6 is arranged on the vehicle chassis 9, and the wheel 6 can roll on the wheel tread 2, so as to realize the movement of the rail vehicle. The guide wheel 7 is arranged on the vehicle chassis 9, and the rotation vector of the guide wheel 7 (i.e., the installation axis of the guide wheel 7) is perpendicular to the running direction of the rail vehicle. The guide wheel 7 rolls with the guide surface and is used to transmit the guide force provided by the guide surface to the vehicle chassis 9 to realize the guidance of the rail vehicle. In the direction perpendicular to the running direction of the rail vehicle, the guide wheels 7 are in a group of two to realize the left and right steering of the rail vehicle. The steering wheel 8 is arranged on the vehicle chassis 9, and the steering wheel 8 can be raised or lowered relative to the vehicle chassis 9. When the steering wheel 8 is in the lowered state, the rotation vector of the steering wheel 8 (the installation axis of the steering wheel 8) is parallel to the rotation vector of the guide wheel 7 (the installation axis of the guide wheel 7), and the steering wheel 8 rolls with the steering surface and is used to transmit the steering force provided by the steering surface to the vehicle chassis to realize the steering of the rail vehicle. In the direction perpendicular to the running direction of the rail vehicle, the steering wheels are in a group of two to realize the left and right steering of the rail vehicle, and the guide wheels of the same group are arranged between the two steering wheels of the same group.

[0076] In the present invention, the chassis 9 is a steel frame chassis, which is welded from square steel pipes. The chassis 9 as a whole is approximately a rectangular structure, and along the length direction of the chassis 9 are the front and rear of the intelligent rail vehicle. A wheel power system is set at the position of the chassis 9 near its two ends (the front and the rear). In the present invention, the wheel power system is a motor power system, and the wheel power system consists of an electric motor, a power supply system, a differential, etc. The wheel power system drives the wheels 6 on both sides of the chassis 9 to rotate, thereby realizing the operation of the intelligent rail vehicle. Corresponding to each wheel 6, the present invention is also equipped with a brake device for realizing the braking of the intelligent rail vehicle.

[0077] The wheel 6 is arranged on the vehicle chassis 9, and the wheel 6 is in rolling contact with the wheel tread 2. Specifically, a wheel axle is installed on the wheel 6, and the wheel 6 is connected to the wheel power system through the wheel axle. The braking device installed on the vehicle chassis 9 acts on the wheel axle or the wheel 6 to realize the braking of the intelligent rail vehicle.

[0078] The present invention installs the guide wheel 7 through the support arm 12, and the support arm 12 is installed on the wheel 6. The wheel 6 is not a simple wheel, but a set of components. The wheel 6 includes a wheel shaft, a bearing seat 6a and a wheel 6b. The wheel 6b is installed on the bearing seat 6a through the wheel shaft. The bearing seat 6a is rotatably installed on the vehicle chassis 9. The bearing seat 6a is connected with a steering rod 13. The support arm 12 is fixedly connected to the steering rod 13, so that the support arm 12 can control the steering of the wheel 6 and stabilize the vehicle body during the driving process of the rail vehicle. Based on the above structural design, the present invention can also realize the linkage between the control arm 11c and the steering rod 13 through a connecting rod structure, so that the rail vehicle can better complete the steering operation.

[0079] The wheels 6b are arranged in pairs. When the rail vehicle is moving straight, the two wheels 6b arranged in pairs are respectively located on two wheel treads 2. When turning, the two wheels 6b can deflect in the same direction at the same time.

[0080] The guide wheels 7 are located on both sides of the vehicle chassis 9 and contact the inner side of the guide rail 3. The guide wheels 7 are connected to the wheels 6 through the support arms 12. During the normal operation of the rail vehicle, the guide wheels 7 cooperate with the guide rail 3 to control the wheels 6 and play the role of a steering wheel. The relative structure between the guide rail 3 and the wheel tread 2 is stable. The guide wheels 7 are installed on the wheels 6 through the support arms 12. The guide wheels 7 contact the guide rail 3, which can make the wheels 6 roll stably on the wheel tread 2. Specifically, the guide wheels 7 are in groups of two, and the two guide wheels 7 of the same group are respectively arranged on both sides of the vehicle chassis 9, and the guide wheels 7 are in rolling contact with the inner side of the guide rail 3. In a preferred embodiment of the present invention, the guide wheels 7 are arranged on both sides of the front end (the front position) of the vehicle chassis 9, so that the front of the vehicle can be ensured to travel in the correct direction. In another preferred embodiment of the present invention, two groups of guide wheels 7 are provided, and the two groups of guide wheels 7 are respectively provided near the front end (front) and rear end (rear) of the vehicle chassis 9, so that it can be ensured that the front part and the rear part of the intelligent rail vehicle can travel in the correct direction, thereby improving the driving stability of the intelligent rail vehicle.

[0081] The steering wheel 8 is a device for realizing the steering of the intelligent rail vehicle in the present invention. Specifically, the present invention installs a steering wheel control device 11 on the vehicle chassis 9. The steering wheel control device 11 includes a control arm. There are four control arms. Each control arm is equipped with a steering wheel 8. The control arm can be raised or lowered to be flat. After the control arm is raised, the steering wheel 8 is separated from the outer side of the guide rail 3. After the control arm is lowered to be flat, the steering wheel 8 is in rolling contact with the outer side of the guide rail 3, so that the steering of the intelligent rail vehicle can be realized. The present invention is not limited to the structural form of the steering wheel control device 11, as long as the control arm in the steering wheel control device 11 can be controlled to be raised or lowered.

[0082] Specifically, the steering wheel control device 11 includes a driving motor 11a, a connecting rod 11b and a control arm 11c. The driving motor 11a is fixedly arranged on the vehicle chassis 9. The connecting rod 11b is slidably arranged on the vehicle chassis 9 in a direction perpendicular to the running direction of the rail vehicle, that is, the connecting rod 11b can slide left and right (the running direction of the rail vehicle is set to the front and rear direction). The control arm 11c is hinged on the vehicle chassis 9 and can be lifted from a horizontal setting state and can be reset from a lifted state to a horizontal state. The driving motor 11a and the connecting rod 11b are connected by a gear system (or a turbine system). The rotation of the driving motor 11a can drive the connecting rod 11b to slide (slide to the left or slide to the right). The connecting rod 11b is linked with the control arms 11c arranged on the left and right sides, so that one of the control arms can be lifted and the other control arm can be lowered, so as to realize the lowering of the steering wheel 8 on one side of the rail vehicle and complete the steering of the rail vehicle.

[0083] The steering wheels 8 are arranged in groups of two, and the two steering wheels 8 in the same group are mutually exclusive and can be raised and lowered. During the operation of the rail vehicle, when the rail vehicle passes through the turnout, the on-board control system of the rail vehicle selects the direction in advance, and controls the steering wheel 8 on the corresponding side to descend and contact the outer wall of the guide rail. The steering wheel 8 cooperates with the guide rail to pull the control arm, forcing the wheel to rotate a certain angle to achieve the steering function. Specifically, the steering wheel 8 can roll in contact with the outer side of the guide rail 3, and the guide rail 3 provides a steering force to the steering wheel 8. When the steering wheel 8 on the left side is lowered and laid flat, the intelligent rail vehicle can turn to the left, and when the steering wheel 8 on the right side is lowered and laid flat, the intelligent rail vehicle can turn to the right. Furthermore, there are two groups of steering wheels 8, and the two groups of steering wheels 8 are respectively arranged near the front and rear ends of the vehicle chassis 9, so that the front end and the rear end of the intelligent rail vehicle can be subjected to the steering force on the same side, so that the intelligent rail vehicle can turn stably.

[0084] The straddle-type intelligent rail vehicle also includes a guide wheel 7, which is used to improve the stability of the intelligent rail vehicle during driving. A steering wheel 8 is provided on the intelligent rail vehicle, and the steering wheel 8 is used to realize the turning (road selection) of the intelligent rail vehicle at a curve (turnout). Specifically, the rotation axis of the guide wheel 7 and the rotation axis of the steering wheel 8 are located in the same vertical plane. Further, the guide wheel 7 and the steering wheel 8 (when the steering wheel 8 is in a lowered and flat state) arranged on the same side are located in the same plane. In this way, when the intelligent rail vehicle turns, the guide wheel 7 and the steering wheel 8 can clamp the guide rail 3, so that the force of the intelligent rail vehicle is balanced, and the stability of the steering of the intelligent rail vehicle is guaranteed.

[0085] In the intelligent rail vehicle, the guide mechanism contacts the guide rail 3 through the guide wheel 7, providing the vehicle with a steering direction and stabilizing the vehicle operation; the steering mechanism is the steering wheels 8 on both sides that are mutually exclusive and can be raised and lowered, pressing the guide rail 3 to achieve the guide selection of the fixed turnout; the power mechanism provides the vehicle with traction and braking functions; the vehicle chassis 9 connects the various mechanisms and provides a load platform.

[0086] The steering mechanism selects the steering wheel 8 to buckle the left or right guide rail 3 by raising and lowering the steering wheels 8 on both sides. The steering wheel 8 cooperates with the guide rail 3 to pull the brake arm 11c to apply a pulling force to the rail vehicle, and at the same time works together with the guide wheel 7 set on the vehicle chassis 9 to realize vehicle steering.

[0087] Regarding the automatic marshaling of intelligent rail vehicles, the present invention sets docking components at the front and rear of the intelligent rail vehicle, such as a conical head docking component and a conical hole docking component. Through the docking of the conical head docking component and the conical hole docking component, the automatic alignment of two intelligent rail vehicles can be achieved. The present invention sets fixed hooks and electromagnetic hooks at the front and rear of the intelligent rail vehicle. The electromagnetic hook can be controlled to flip. When the two intelligent rail vehicles are automatically marshaled and docked, the electromagnetic hook can be controlled to rotate and hooked together with the fixed hook. When the two intelligent rail vehicles are automatically disassembled, the electromagnetic hook can be controlled to rotate in the opposite direction (or reset after power failure) and separate from the fixed hook. The present invention sets male and female plugs at the front and rear of the intelligent rail vehicle to achieve the docking of signal lines.

[0088] 3. Autonomous driving control system

[0089] The automatic driving control system is divided into three parts: one part is the system installed on the intelligent rail car, including the on-board control system and the passenger information system; one part is the background system installed at the platform, including the automatic train monitoring system and the rail transit automatic ticket vending and checking system; one part is the intermediate signal transmission and trackside signal system, including information access point equipment, transponders and trackside controllers, and communication cables.

[0090] In the autonomous driving control system:

[0091] The vehicle-mounted control system is arranged on the straddle-type intelligent rail vehicle and is used to run the vehicle-mounted control program to realize the automatic driving of the straddle-type intelligent rail vehicle;

[0092] A passenger information system is provided on the straddle-type intelligent rail vehicle and is used to display operation information of the straddle-type intelligent rail vehicle and public media information in the straddle-type intelligent rail vehicle;

[0093] Information access point equipment is arranged along the main body of the track and is used for information interaction of straddle-type intelligent rail vehicles;

[0094] Transponders and trackside controllers are placed along the track body and are used to send information to the onboard control system and passenger information system;

[0095] A transponder antenna is provided on the straddle-type intelligent rail vehicle and is used to receive information sent by the transponder and the trackside controller;

[0098] The rail transit automatic ticket vending and checking system is connected to the communication cable and sends ticket information to the straddle-type intelligent rail vehicle through the information access point equipment, the transponder and the trackside controller.

[0099] Information access point device, i.e. Figure 6 The AP in it, that is, the information access point AP, has the following functions: to carry out vehicle-ground communication, the rail vehicle reports its own position during driving, and at the same time, the trackside sends the position of the preceding vehicle, so that the rail vehicle can be automatically controlled according to the distance between the front and rear vehicles through the on-board control system and the automatic train monitoring system.

[0100] The function of the transponder and the trackside controller is to carry position information representing the position of the transponder and the trackside controller, which is used by the rail vehicle to confirm its own position information.

[0101] The present invention uses an automatic driving control system to automatically control the operation of the vehicle through the cooperation of onboard and trackside signal equipment. The automatic driving control method can reduce the number of operation control personnel, especially for small carriages, each with only 2 to 4 passengers. The number of vehicles to achieve the same passenger flow must be large. Automatic driving greatly reduces the number of drivers and is the key to realizing personal transportation.

[0103] VOBC is the abbreviation of vehicle on-board controller, which is the on-board controller responsible for completing the on-board ATP / ATO functions. The on-board controller continuously communicates with the train control center and performs traction, braking and door control under ATP protection. ATO is the automatic train operation device (called Automatic Train Operation in English). The ATO device allows the train to automatically start and stop, and automatically open and close the doors without anyone driving (sometimes with driver monitoring). When there is a driver in the cab, the driver can also be responsible for opening and closing the doors. After closing the doors, press the start button, and the train will automatically start and drive according to the instructions of the signal system, and automatically stop when it arrives at the stop station. The ATP subsystem (automatic train protection system) is a safety control system that ensures that the train speed does not exceed the target speed. It is a subsystem of the automatic train control (ATC) system and is also a key equipment to ensure the safe operation of the train and achieve overspeed protection. This subsystem continuously transmits information such as "target speed" or "target distance" to the train through the ATP ground equipment installed on the trackside to maintain a safe interval between the following train and the leading train, and supervises the program control of the opening and closing of the train doors and platform screen doors to ensure their safe operation.

[0105] PIS is the abbreviation of Passenger Information System, which refers to a multimedia comprehensive information system that relies on multimedia network technology, takes computer system as the core, and allows passengers to understand train operation information and public media information in a timely and accurate manner through the train's display terminals.

[0106] ATS is the abbreviation of Automatic Train Supervision, which means automatic train monitoring system. As an important subsystem of the ATC system, the ATS subsystem is a distributed real-time monitoring and control system that integrates modern data communication, computer, network and signal technology. The ATS subsystem manages and controls subway operating trains and signal equipment through coordination with other subsystems in the ATC system.

[0107] AFC is the abbreviation of Automatic Fare Collection System, which is the automatic ticketing and checking system for urban rail transit. It is a closed automated network system that is centrally controlled by computers for automatic ticketing (including semi-automatic ticketing), automatic ticket checking, and automatic toll collection and statistics. The AFC automatic ticketing and checking system is based on computer, communication, network, automatic control and other technologies, and can realize the automatic ticketing, ticket checking, billing, toll collection, statistics, clearing and management of rail transit.

The electromagnet 15 can drive the movable connection lock tongue 14 to rotate by the presence or absence of magnetic attraction (the power on or off of the electromagnet 15 determines the presence or absence of magnetic attraction), so that the movable connection lock tongue 14 maintains a fixed locking state or a loosened release state relative to the vehicle chassis 9.

[0113] 3. Fixed connection lock tongue 16
