Send registration instruction: When the vehicle enters the straight track, after the vehicle's track signal receiving device detects the signal from the track signal transmitting device, the vehicle's wireless communication device sends the vehicle number and the information of the destination station, and the track computer performs the operation after receiving the vehicle operation information. Registration; Checking the running section and sorting: After the vehicle information receiver of the track detects the vehicle information and receives the vehicle registration information, the track computer sends the section code, the serial number of the vehicle running in the section, and the vehicle running speed; the vehicle receives After the information and instructions from the track computer are checked, they are checked with the running line. The track computer sends the running information of the vehicle to the single-chip microcomputer at the branch road ahead of the vehicle: vehicle number, serial number, and destination station.

The vehicle may be driven in a virtual train mode, and the steps of the virtual train mode are as follows:

Ranging: The electronic distance measuring device installed on the front of the vehicle continuously measures the distance from the front vehicle during operation. The main control microcomputer of the vehicle controls the vehicle speed according to the distance; when the distance is greater than the threshold, The vehicle runs at the speed specified by the track computer;

Chase: When the distance is less than the threshold, the leading vehicle information receiver of the following vehicle can receive the running information of the preceding vehicle, and the main control microcomputer controls the own vehicle to chase at a speed greater than the preceding vehicle according to the speed of the preceding vehicle. The speed difference between the two vehicles has a linear relationship with the distance between the vehicles. If the distance between the vehicles is close to zero, the difference in the speed of the vehicles is also close to zero.

Virtual train operation: When the vehicle distance is close to zero and the collision occurs, the vehicle's collision buffering device plays a buffering role. The sensor provides the collision information to the main control microcomputer. The main control microcomputer reduces the speed of the vehicle until it is out of the collision. The rear vehicle is continuously adjusted. Speed until the speed of the two cars enters the virtual train operation mode simultaneously.

The steps for the vehicle to arrive at the station are as follows:

Drive into the platform track: When the vehicle passes through the fork in the station, it is controlled by the vehicle steering control device, and the vehicle enters the platform track;

Stopping at the platform: After the vehicle enters the platform track, it will drive to the forefront of the platform. When there is a vehicle parked in front of the platform, the vehicle will automatically adjust the speed and park at the back of the front vehicle. After the vehicle has stabilized, it will automatically open the door;

Stopping to the parking track: After the passengers have finished getting off the vehicle, the vehicle automatically closes the door, follows the vehicle in front to the parking track, and stops on the track after entering the parking track;

Parking registration: When the vehicle enters the parking track, the vehicle registers with the microcontroller of the parking track.

The transportation organization of the small vehicle rail transportation system is different from that of the traditional rail transportation: the traditional transportation organization is implemented by the dispatch control center as planned, while the system is implemented by the computer dispatch center of each station as needed.

The transportation organization method of the small vehicle's rail transit system is that the dispatching computer at the departure station randomly sends the vehicle as needed; the autonomous vehicle prepares its own operation plan and chooses the route to the destination station; the unmanned small vehicle is on a closed track to The chase mode constitutes a virtual train operation.

Another advantage of the present invention is that compared with other rail transits, it can greatly reduce construction investment, reduce operating costs, improve safety performance, and facilitate rail network connectivity when compared to other rail transits.

In addition, the present invention also has the following advantages:

Reduce construction investment:

Compared with the subway and light rail vehicles, the small vehicles used in the present invention are greatly reduced. The load on the unit length track can be simplified, which can simplify the track structure; the vehicle's cross section is small, reducing the tunnel diameter, and reducing the amount of tunnel work; the vehicle's departure station runs directly to the destination station, canceling the transfer station; the platform's platform length is based on passenger flow Design, greatly reducing the platform length of small and medium passenger traffic stations, reducing the construction scale of the station; replacing the dispatching control center with an information center, and replacing the signal system with an information system; reducing the garage area of the vehicle depot, and reducing Factors such as the size of the overhaul workshop have significantly reduced the construction scale and project investment. In addition, vehicles based on electronic systems have replaced vehicles based on machinery. The use of ground-based control measures has reduced the vehicle's intelligence requirements and fully reduced vehicle investment.

Reduce operating costs: Reduced station size, corresponding reduction of electromechanical equipment, reduced energy consumption and maintenance costs; On-demand departures instead of scheduled departures, reducing operating costs outside peak hours; reducing construction costs and reducing interest on purchases And depreciation expenses, etc.

Improved safety performance: The system uses chase technology with zero blocking distance to avoid rear-end collisions; Ping-pong control at merged intersections prevents side collisions between vehicles; use of forward-connected return lines to eliminate U-turn lines Avoid accidents caused by turnouts. Dozens of subway lines in the world have adopted autonomous driving. Practice has proven that the safety performance of autonomous driving is superior to manual driving. Because the battery is used as the (backup) power source, the vehicle can continue to drive away from the scene of the accident and so on during a power outage.

Facilitate the connection of rail transit: This system uses ground transportation, which is equivalent to a single-lane expressway connected to a non-transfer rail transportation system; the system is not only suitable for trunk and ring traffic, but also for distribution and distribution traffic. Rail transit network.

This system is a combination of mature technologies: using conventional computer control, ordinary computers and single-chip computers; vehicle control is also simpler than existing electric cars, only controlling the speed of forward; simple wireless communication is used to transmit low-speed data, and the communication distance is close The requirements are low. The present invention decomposes a complex technology into several simple technologies, and decomposes a difficult closed-loop control into an open-loop problem for processing. The present invention relates to a wide area and requires the collaborative development of general technical personnel of multiple disciplines and specialties.

Therefore, the system is an urban rail transit system with less investment, large transportation volume, high efficiency, good service, less pollution, less land occupation and easy development. Related technical information:

The present invention is described in detail below with reference to the drawings:

(1) System:

Figure 1 shows the rail transit system for small vehicles in a single transport direction. The system mainly includes small vehicles 1, closed tracks 2 and stations 3, of which closed tracks have straight tracks 2, bifurcation junctions 4, and merged junctions 5. In addition, the fish straight track 2, the bifurcation intersection 4, and the merge intersection 5 are combined to form an intersection road track, which can connect the tracks into a track network.

Each station 3 has an entrance and an exit in each transport direction. The tracks at the entrance and exit of the station are connected to the section track 2 to form a complete transport line track. The vehicle runs on this track according to the transportation requirements. . The present invention adopts the habit of the railway. The transportation direction (the direction of the arrow in FIG. 2) is divided into an upward direction and a downward direction, and each station has a unique number according to the upward direction and the downward direction.

Each straight track 2 is a closed track (in the direction of transport) with only one entrance and one exit. Bifurcation intersection 4 refers to a closed intersection with one entrance and two exits. As shown in Figure 1, the entrance of bifurcation junction 4 is connected to the exit of track 2, and its two exits are connected to the entrances of the two tracks 2 respectively. Merging junction 5 is a closed junction with two entrances and one exit. As shown in FIG. 1, the two entrances of the merged junction 5 are connected to the exit of the two Chennai track 2, And one of its exits connects to the entrance of a track 2. Similarly, each track and intersection has a unique number.

Vehicle 1 can run on the track alone, or it can automatically form a virtual train 8 to run.

As shown in FIG. 4, a vehicle steering control device 24 is installed at the bifurcation intersection 4. When the vehicle steering control device works, the vehicle is controlled to drive to the fork. A single-chip microcomputer is arranged at the intersection for management. It collects the detection signals of the vehicle information receiver and controls the operation of the vehicle steering control device.

As shown in FIG. 5, the merged junction 5 has two routes. To avoid side collisions of vehicles on the two routes, a speed control device 26 is installed on each of the two routes. The two vehicle speed control devices 26 are managed by a single-chip microcomputer. The two devices work in a ping-pong state. When one allows the vehicle to pass, and the other rotates at zero speed, the vehicle is prohibited from passing.

The rail transit system of the present invention uses a large number of small transport vehicles to form a virtual train running on section rails. Their hourly one-way cross-section passenger flow is equivalent to that of a subway. An example is as follows:

O For example: The vehicle is 4 meters in length, the interior space is 3 meters in length, and 1.6 meters in width; there are 6 seats on one side, and 4 seats and 1 meter wide doors on the other side. Each vehicle can seat 10 people. ; With a speed of 40 km / h and an average vehicle interval of 1 meter, the passenger capacity of the unidirectional track cross section is one of the maximum transport capacity:

40 km / h X 200 vehicles / km X10 people / vehicle = 80,000 people / hour; generally should be controlled between 40,000 people / hour to 60,000 people / hour.

The need to increase transportation capacity requires a reduction in personalized service capabilities. Conversely, it can increase personalized service capabilities.

The passenger volume of a unidirectional track section of a general subway is 40,000 to 60,000 people / hour;

Generally, the cross-section passenger traffic of the unidirectional track of the light rail is 10,000 to 30,000 people / hour.

To improve the passing capacity of vehicles when passing through the station, the technical scheme adopted is similar to the track layout of railway stations. There are main lines for passing vehicles and side lines for passengers to get in and out of the station. Bifurcation junctions, through tracks, Platform tracks and junctions of exit stations constitute the track network. Reduce the impact of vehicles to (stop) and (departure) on through vehicles, and reduce the impact of slow-moving passengers on and off.

(II) Track:

Figure 2 shows a schematic diagram of the bidirectional straight orbit of the interval, which is similar to the orbit of the German 0-Banh system (Page 82 on Source 8). Figure 3 shows the two-way straight track of the interval Schematic diagram of the end-view structure in the I-I direction. Guardrails installed on each side of each one-way track

22. Track surface 21, bracket 31, a leaky cable 23 for wireless communication is installed on the left side of the track in the vehicle running direction; a vehicle information receiver 29 is installed at the entrance of the vehicle running direction, and a vehicle detection Orbit signal transmitting device 30. The track signal transmitting device 30 sends a signal indicating that the vehicle has entered a new track. A device sealing cabinet 32 is set on the outside of the track, and equipment such as a track computer 201 and a track radio 210 are placed inside the device sealing machine 32.

(1) Track structure

The function of the guardrail 22 in Figure 2 is to guide the running of the vehicle. It is connected by smooth steel plates, and the width of the board is larger than the range of the vehicle (guide) positioning wheel (see Figure 18). The track surface 21 is a reinforced concrete road surface. It can be a monolithic pavement or two reinforced concrete pavements connected by reinforced concrete. The intersection and the station can use the monolithic reinforced concrete pavement, and the straight track can use two reinforced concrete pavements connected by the reinforced concrete. The bracket 31 is suitable for an elevated line and is fixed on an elevated bridge. It is a reinforced concrete prefabricated part that supports both the track surface 21 and the fence 22. In the tunnel and ground lines, the track surface 21 is directly placed on the ground. The bracket 31 is An upright post is only used to secure the fence 22.

(2) Marking device for orbital operation

The marking device for track operation includes a vehicle information receiver 29 and a track signal transmitting device 30. The vehicle information receiver 29 in FIG. 2 is used to detect the passage of the vehicle, and the track signal transmitting device 30 is used to detect whether the vehicle has entered a new track.

The installation positions of the vehicle information receiver 29 and the track signal transmitting device 30 correspond to the installation positions of the vehicle information transmitting device 54 and the track signal receiving device 52 of a marking device for vehicle operation which will be described in detail later. The marking device for rail operation and the marking device for vehicle operation which will be described in detail later constitute the marking device of the operating system. When the vehicle passes, the track's vehicle information receiver 29 receives or detects the information from the vehicle information transmitter 54 to determine the passage of the vehicle. Similarly, when the vehicle enters a new track, the vehicle's track signal receiving device 52 receives or detects the information from the track signal transmitting device 30 to determine that the vehicle has entered a new track.

The vehicle information receiver 29 detects the vehicle passing through and the track signal transmitting device 30 to detect the vehicle entering a new track. Many existing detection methods can be used, for example: a signal lamp (such as a light-emitting tube, etc.) using light signal principle and light receiving Devices (such as photosensitive devices), magnets using magnetic technology (such as electromagnets), and Hall devices (such as reeds) Relays), transmitters and receivers that use wireless sign signals, etc .; optoelectronic emitters 27 and shading plates 28 that use the shading principle are also one of them. Specifically: The vehicle information receiver 29 is one of a light receiver, a photosensitive device, a Hall device, and a reed relay, and a corresponding vehicle information transmitter 54 which will be described in detail later is a signal lamp, a light emitting tube, and a magnet. A corresponding one of the electromagnets; the track signal transmitting device 30 is one of a signal lamp, a light-emitting tube, a magnet, and an electromagnet, and a corresponding track signal receiving device 52 mounted on a vehicle to be described later is a light The corresponding one of a receiver, a photosensitive device, a Hall device, and a reed relay.

The optoelectronic radiator 27 is composed of a light transmitter and a light receiver. The light receiver usually receives the light signal emitted by the light transmitter and outputs a high-level DC signal. When a light shielding plate 28 blocks the middle of the radiator 27 When light is emitted, the optical receiver cannot receive the optical signal and outputs a low-level DC signal. The photoelectric radiator 27 and the light shielding plate 28 are respectively installed on a track and a vehicle that are relatively moving, and are used for track detection of a vehicle and a vehicle detection track.

As shown in FIG. 26, the vehicle information receiver 29, the track signal transmitting device 30, and the track wireless communication device 210 are all connected to the track computer 201. When the vehicle enters a section of track, the vehicle information receiver 29 detects a signal from the vehicle information transmitter 54 when the vehicle passes, and generates a pulse signal to send to the track computer 201; the track signal sending device 30 can be controlled and sent by the track computer 201 It can also be continuous transmission under manual control.

(3) First orbit wireless communication device installed on the orbit

The first track wireless communication device mounted on the track and the second track wireless communication device mounted on the vehicle to be described in detail later realize communication between the vehicle and the track. The first orbit wireless communication device and the second orbit wireless communication device constitute an orbit wireless communication system.

The first rail radio communication device includes a leak cable 23 and a rail radio communication device 210. As shown in FIG. 2, FIG. 3 and FIG. 30, one end of the leakage cable 23 is connected to the antenna port of the track wireless communication device 210 with a low-loss cable 231. The leakage cable 23 is equivalent to a very long distributed antenna. An area of (signal) field strength emitted by the orbital radio communicator 210 is formed around, and the corresponding on-board orbital radio communicator 410 can receive the signal transmitted by the orbital radio communicator 210; Since the radio wave propagation is bidirectional, the on-board orbital radio communicator The signal from 410 is received by the track radio communication device 210 through the leak cable 23. The characteristics of a track wireless communication device using a leaky cable 23 are: its communication range is only a few meters around the leaky cable, that is, the range of wireless communication can be set up with a leaky cable Take control.

The track radio 210, track computer 201 and other circuits are placed in a sealed equipment box 32, and the cabinet is installed near the entrance of the track. A low-loss connection cable 231 is connected under the track surface 21 to connect the antenna interface of the track wireless communication device 210 and one end of the leakage cable 23. Orbital entrances in the other direction are also similarly installed with orbital radio communicator 210, orbital computer 201 and the like. That is, the two ends of the leaky cable 23 are connected to the uplink and downlink orbital wireless communicators 210, respectively. The leaky cable 23 transmits the two (uplink and downlink) orbital wireless communication transmit signals and the two orbital wireless communication receive signals. The uplink orbit wireless communication system and the downlink orbit wireless communication system respectively use different frequency groups.

The leakage cable 23 is a coaxial cable that can leak the electromagnetic field in the cable to the outside of the cable, and can also induce the electromagnetic field outside the cable to the inside of the cable. It differs from ordinary coaxial cables in that the outer conductor is slotted or has a gap, and it is characterized by both a transmission line and radiated energy along the line. Leakage cable 23 has standard products. It is divided according to the slotting method. There are two types of commonly used leakage cables: slotted (shaped) slot and slotted slot. There are three types of frequency bands: 450MHz, 150MHz, and 450MHz and 150MHz integrated frequency bands. In addition, there are broadband leaky cables whose outer conductor is a thin braid. Leaky cables have been widely used in subways, railway mountains and tunnels, and road tunnels on the river bottom.

As shown in FIG. 31, each track and intersection has a wireless communication area constituted by a leaky cable 23 connected by a track wireless communicator 210, and the track wireless communicator 210 and the vehicles 1 in this area constitute a radio around the track. As for the communication network, FIG. 31 is a plurality of rail wireless communication networks composed of a plurality of rail computers 201 and a vehicle 1 via a rail wireless communication device 210 and a leak cable 23. The main control microcomputer 401 of the vehicle implements data communication with the orbital computer 201 through the orbital wireless communication network. As shown in FIG. 31, vehicle A and the orbital computer b perform wireless data communication, while the vehicle N and the single-chip microcomputer e at the merged intersection of the station K + 1 perform Wireless data communication.

Orbit wireless communication uses a unified set of two frequencies (one for each of the uplink and the downlink), a modulation method, a data structure, a transmission rate, and an error correction method. It is best to use the half-duplex communication method (frequency approved by the Radio Regulatory Commission) in the 450MHz band. The fixed wireless communication device 210 in the orbit is a duplex communication device. Its transmission frequency is the high-end 460MHz frequency band. The mobile communication device 410 of the vehicle It is an inter-frequency simplex wireless communication device, and the transmission frequency of the vehicle is a frequency of a low-end 450 MHz band. The modulation method can be frequency modulation, phase modulation or other modulation methods. Adopt asynchronous serial communication mode with parity bit. Commonly used The speed is 2400 baud, 4800 baud, 9600 baud, etc.

(4) Registration, sequencing and checking of vehicle operation

When Vehicle 1 enters a section of track (including an intersection), it needs to be registered, sorted and checked once. The process is illustrated in conjunction with Figure 38:

When vehicle 1 enters the new track area, ① the track signal receiving device 52 of vehicle 1 also receives the signal from the track signal sending device 30 of the track, and generates a pulse to be sent to the main control microcomputer 401; ② the track vehicle information receiver 29 receives The signal to the vehicle's vehicle information transmitter 54 also generates a pulse to send to the track computer 201, and the track computer 201 records the number of vehicles entering; ③ After receiving the pulse signal, the vehicle's main control microcomputer 401 confirms that the vehicle has entered a section of track. The vehicle's operation registration and verification information (vehicle fixed number, operation destination station, exit direction in front of the intersection) are transmitted to the orbit computer 201 via the vehicle wireless communicator 410 and the orbit wireless communicator 210; ④ orbit computer 201 via orbit wireless The communicator 210 and the vehicle wireless communicator 410 send a response check and ordering instructions to the main control microcomputer 401 (vehicle fixed number, track number of this section, vehicle serial number m in this section, permitted operation in this section Speed); ⑤ The vehicle checks this instruction, and Adjust the running status of the vehicle; ⑥ The track computer 201 has registered the vehicle and sent the vehicle running information (vehicle serial number m, track number, the number of the intersection behind, the direction after passing the intersection) to the microcontroller of the next intersection. The serial number of the vehicle uses 1 byte-256 numbers, which is used cyclically, that is, from 00H (0) to 0FFH (255), and then to 00H (0) .......

(5) Bifurcation:

FIG. 4 shows the track structure of a one-way bifurcation intersection. A vehicle information receiver 29 and a track signal transmitting device 30 are installed at the entrance. A vehicle steering control device 24 controlled by a single-chip microcomputer 202 is installed at the branch. A pressure-sensitive device 246 is installed on the track surface 21 at the rear of the device 24. Several pairs of vehicle positioning wheels 25 are installed at the two exits of the bifurcation. The spacing of the first pair of positioning wheels is slightly wider. The spacing of the rear positioning wheels is slightly wider. gradually decreases.

O For example: The thickness of the track control board 51 may be 4mm, the distance between the first pair of wheels may be 30cm; the second pair is installed at 0.5m from the first pair, and the distance between the wheels is 20cm; at the back 0.5m The distance between the third pair of wheels is 10cm; the distance between the fourth pair of wheels behind 0.5m is 5cm; the last pair is 2cm.

The vehicle information receiver 29 and a track signal transmitting apparatus 30, the distance from the vehicle steering control apparatus 2 is 20m- 30m _o

The vehicle steering device 24 is a pair of conveyor belts mounted in opposite directions on a track. 244. When the left conveyor belt 244 is driven forward and the right conveyor belt 244 is driven backward, the vehicle 1 turns to the right with the cooperation of the vehicle steering control device 24 toward the fork. As shown in FIG. 16, the conveyor belt 244 is driven by a driving shaft 241 and supported by a passive shaft 242. The driving shaft 241 is connected to a low-speed motor 243 or a motor with a transmission. A pressure-sensitive device 246 is installed on the ground at the exit of the belt 244. Various standard products of the prior art can be selected for 246; the motor 243 is controlled by the single-chip microcomputer 202, and the output signal of the pressure-sensitive device 246 is sent to the single-chip microcomputer 202. When the rear wheel of the vehicle is pressed on the pressure-sensitive device 246, the single-chip microcomputer 202 receives the pressure-sensitive device The high-level signal output by 246 indicates that the vehicle has passed the vehicle steering device.

As shown in Fig. 37, ① the single-chip microcomputer 202 at the bifurcation intersection receives the operation information of the vehicle transmitted by the track computer 201 before the vehicle reaches the intersection; ② after the vehicle enters the bifurcation intersection 4, the same as the straight track 2, the vehicle 1 detects The signal sent by the track signal transmitting device 30; ③ The single-chip microcomputer 202 of the bifurcation intersection 4 also detects the signal of the vehicle information transmitter 54 and the single-chip microcomputer 202 counts; ④ The main control microcomputer 401 of the vehicle 1 sends the bifurcation road through the track wireless communication system The single-chip microcomputer 202 at the port 4 sends the vehicle's operation registration and verification information (sending the serial number of the vehicle, the operating destination station, and the direction of the exit of the intersection); ⑤ The single-chip microcomputer 202 sends the response command after receiving the operation information sent by the vehicle 1 via track wireless communication (vehicle Serial number, the number of this intersection). Vehicle 1 was registered at the single-chip microcomputer 202 at the fork, and Vehicle 1 also checked the driving route.

FIG. 37 also shows the process of the virtual train 8 passing through the branch 4: ① Before the vehicle 1 reaches the branch 4, the single-chip microcomputer 202 at the branch has received the operation of the number m and m + 1 vehicles sent by the track computer 201 Information, which records the running information of vehicle m and the turning information of vehicle m + 1. That is, car No. m goes straight, and car No. m + 1 needs to turn. ⑥ When the rear wheel of car No. m is pressed on the pressure sensitive device 246, ⑦ the single-chip microcomputer 202 receives the high-level signal output from the pressure sensitive device 246, The vehicle m has passed the vehicle steering device 24; ⑧ the single-chip microcomputer 202 at the bifurcation intersection starts the vehicle steering control device 24 to operate; ⑨ when the vehicle m + 1 arrives, it controls the vehicle m + 1 to turn to the fork. On the contrary, when the rear wheel of the turning vehicle in front is pressed on the pressure-sensitive device 246, the single-chip microcomputer 202 receives the high-level signal output from the pressure-sensitive device 246, and the intersection single-chip microcomputer 202 controls the vehicle steering control device 24 to stop working. If the front and rear vehicles go in the same direction, although the single-chip microcomputer also receives the high-level signal output from the pressure sensitive device 246, it does not change the working state of the vehicle steering control device 24.

The single-chip microcomputer 202 determines that the running direction of the vehicle is based on the vehicle running information (vehicle serial number, destination station, and exit direction) sent by the track computer 201; the vehicle 1 enters the bifurcation intersection 4 At the time, the single-chip microcomputer 202 counts; the vehicle running information (vehicle serial number, destination station, exit direction of the intersection) sent by vehicle 1. Therefore, each vehicle before the arrival of the vehicle steering control apparatus 24, the microcontroller 202 to the outlet direction of the vehicle by a steering control of the vehicle control apparatus ²⁴ is operating in. Virtual train 8 passes bifurcation 4 and is the most demanding. The following illustrates the operation of the vehicle steering control device 24 when the virtual train 8 passes through the bifurcation intersection 4:

O For example: As shown in FIG. 40, the conveyor belt 244 of the vehicle steering control device 24 is about 1 meter long and greater than 40 cm wide, and the maximum running linear speed is 1 meter / second; the virtual train 8 is driven at 40 kilometers / hour (about 11 meters / Seconds), the passing time of each wheel 502 on the conveyor 244 is 0.09 seconds; the actual travel deviation of the left and right wheels of the vehicle is 2X 0.09 meters = 0. 18 meters; when the vehicle length is 4 Meters, the track distance between the front and rear wheels is 2 meters, and a deflection of 5 is generated after the vehicle passes the vehicle steering control device 24.

Vehicle steering control apparatus 24 starts selecting the acceleration is 10 m / s ^2, number m of the current vehicle wheel by conveyor belt 244 (the device is pressed against the pressure-sensitive), motor starting, just reached 0.1 seconds Stable speed (this can be done by ordinary motors); while the front wheel of the rear car number m + 1 reaches the conveyor 244, it takes 0.1 second, the conveyor 244 has reached a stable speed; similarly, the stop time of the conveyor Can also meet the requirements.

When vehicle 1 passes through branch 4, the position may deviate, causing the vehicle to hit the guardrail. Several pairs of vehicle positioning wheels 25 are installed at the branch exit. As shown in FIG. 4, when the vehicle 1 is moving forward, the vehicle's track control board 51 enters the first pair of positioning wheels 25 and gradually passes through the second pair and the third. Equivalently, the vehicle is positioned in the center of the track to prevent it from hitting the guardrail.

FIG. 13 is a schematic structural diagram of a vehicle positioning wheel 25. Two rubber wheels 250 are respectively fixed on two shafts 251 through bearings 252. The shaft 251 and the bracket 253 are floatingly fixed. The distance between the two shafts is larger than the track control board 51 of the vehicle. The distance between the wheels of the first pair is the largest, and the distance between the wheels of the subsequent pairs gradually decreases.

(6) Merged intersection:

The one-way merge intersection 5 track structure shown in FIG. 5 is installed at the entrance of the two tracks, respectively, a vehicle information receiver 29 and a track signal transmitting device 30, and a pair of positioning wheels 25 and a speed control device 26. On the ground behind the device 26, where the wheels can be pressed, pressure-sensitive devices 246 are installed, and several pairs of positioning wheels 25 are installed at the combined exit. The general distance between the vehicle information receiver 29 and the track signal transmitting device 30 from the vehicle speed control device 26 is 20m-30m.

The vehicle speed control device 26 is a pair of The rotating wheel 260 fixed on the shaft 261, the shaft 261 of which is fixed on the bracket 263 through the bearing 262; the gap between the two rotating wheels 26G is equal to the thickness of the track control plate 51 under the vehicle chassis, and can closely fit; The root shaft is connected to a motor 265 controlled by a single-chip microcomputer 203 through a gearbox 264.

The single-chip microcomputer 203 at the intersection 5 controls the speed control device 26 of the two routes. The ping-pong method is adopted, that is, the vehicles of one route are released, and the vehicles of the other route are stopped. Management and control rules of the single-chip microcomputer 203: Generally, it is first-come-first-served; when the two vehicles arrive at the same time, the main road takes priority (artificially defined); when the virtual train 8 of the main road passes, the virtual train 8 passes and is released Side road vehicles.

Figure 36 is the specific process of vehicles passing through a merged intersection:

Before the vehicle reaches the merged intersection, the single-chip microcomputer 203 of the merged intersection 5 has received the vehicle operation information transmitted by the two routes; ① When the vehicle m of the track A reaches the entrance of the merged intersection 5, the track signal receiving device 52 of the vehicle _m The signal from the track signal transmitting device 30 is detected; ② The vehicle information receiver 29 of the track detects the signal from the vehicle information transmitter of the vehicle; ③ The main control microcomputer 401 of the vehicle m is integrated with the single-chip microcomputer of the intersection 5 through the track wireless communication system 203 performs registration and verification communication; ④ vehicle m + 1 of track B arrives at the intersection, and vehicle m + 1 detects a signal; ⑤ the single-chip microcomputer 203 at the merged intersection also detects the information of vehicle m + 1's entering intersection; ⑥ vehicle m + 1 Register and check.

The single-chip microcomputer 203 at the junction 5 records the vehicle serial number of each route in chronological order; the single-chip microcomputer 203 queues according to the arrival time of the vehicles and releases the vehicles according to the arrival sequence of the two routes. ⑦SCM 203 sends a full-speed pass command to the passing vehicle through the track wireless communication system; ⑧Same speed deceleration command is also sent to the forbidden vehicle; ⑨SCM 203 controls the speed control device 26 to release the first arriving vehicle. By analogy, each time the single-chip microcomputer at the intersection switches and releases, the single-chip microcomputer sends separate instructions for passing and decelerating to the vehicle.

Method for judging a virtual train by the single chip microcomputer 203 of the merge intersection 5: When the vehicle 1 passes the entrance of the merge intersection 5, the vehicle information receiver 29 on the track receives a signal from the vehicle information transmitter 54 of the vehicle, and the vehicle information receiver 29 generates a The pulse is sent to the single-chip microcomputer 203, and when the virtual train 8 passes, a uniformly spaced pulse train is generated, and the pulse interval is about 0.36 seconds (vehicle speed is 40 km / h). The single-chip microcomputer 203 judges that when the pulse interval is less than 0.45 seconds (a virtual train with a speed of 32 km / h, or a vehicle with a speed of 40 km / h and an interval of 1 meter), it is considered that the virtual train passes.

When the vehicle speed control device 26 is in the braking state, the vehicle 1 receives a single piece of the merged intersection 5 The deceleration command of the engine 203, the track control board 51 of the vehicle chassis is tightly stuck in the speed control device 26, and the vehicle stops at the speed control device 26; when the speed control device 26 runs at a certain speed, the vehicle 1 In accordance with the speed command of the single-chip microcomputer 203, when entering the vehicle speed control device 26, it runs at the speed of the vehicle speed control device 26. In short, the vehicle 1 and the vehicle speed control device 26 operate at the speed specified by the single-chip microcomputer, and the operation speed of the vehicle speed control device 26 is the actual operation speed.

The running speed of the vehicle speed control device is determined by the rotation speed of the motor 265, and the single-chip microcomputer 203 controls the speed of the motor through the driving circuit.

The operating speed of the vehicle speed control device 26 is controlled by a distributed control system composed of a track computer 201. The existing distributed control system can be used.

The line relationship table lists the line relationships of the cross stations ① Cross station 1: A4 / B2 (41, X4, 42, Y2), ② Cross station 2: A10 / B10 (41, XA, 42, YA). (7) Power supply

The power source can be selected as required, one is powered by the battery, and the other is based on the ground power supply system, with the battery as a backup. Both types of power supply have applications. For example, electric vehicles are powered by batteries, while trolleybuses on Chang'an Street use the latter.

(8) Vehicle operation

The main control microcomputer 401 is an embedded microcomputer. The memory of the microcomputer stores electronic maps of the stations, parking lots, various tracks, and intersections of the system. When the departure station and the destination station are determined, the main control microcomputer 401 compiles an operation plan (determines the driving route) by itself, and directly goes from the departure station to the destination station.

Taking the above database as an example, when the departure station and the destination station are determined, the vehicle's main control microcomputer compiles the operation plan by itself.

◊Example: The vehicle departs from station A14 to station B17.

First, confirm the line where the departure and destination stations are located. A14 is on line 1 and B17 is on line 2.

Retrieve the intersections of lines 1 and 2: A4 / B2 and A10 / B10 (check the line number of the code); Vehicle selection route: Under normal circumstances, first select the nearest intersection, A10 / B10 station; Determine the operation line: Vehicle Passing stations A14, A13, A12, All, A10 / B10, Bll, B12, B13, B14, B15, B16, B17; Vehicles are driving on the upward line in sections A14 to A10, and driving in sections B10 to B17 Downlink lines; then the operating lines are A14 (41, 0E), al3 (81, 0D), A13 (41, 0D), al2 (81, 0C), A12 (41, 0C), all (81, OB), All (41, 0B), alO (81, 6A), A10 (41, 6A); At A10 / B10, the vehicle changes from the upward line of line 1 to the downward line of line 2, A10 (41, 6A), B10 (42 , EA), blO (82, CA), B11 (42, 8B), bll (82, 8B), B12 (42, 8C), bl2 (82, 8C), B13 (42, 8D), bl3 (82, 8D), B14 (42, 8E), bl4 (82, 8E), B15 (42, 8F), bl5 (82, 8F), B16 (42, 90), bl6 (82, 90), B17 (42, 91) ). (Because each station has bifurcations and junctions, the intersection codes for each station are listed in the table in the operation plan).

When Vehicle 1 runs to a section of track, it must be registered, checked and sorted; it must also be registered and checked at each intersection. The process of registration, verification and ordering has been described in (4) of the section (2) Track. When the vehicle 1 passes the branch 4, the vehicle 1 continues to go straight. With the cooperation of the vehicle steering device 24 at the intersection, the vehicle runs according to the operation plan. The specific process has been described in (5) of the (II) orbital section.

When vehicle 1 passes through merged intersection 5, vehicle 1 passes through merged intersection 5 at the speed specified by the single-chip microcomputer 203 at the intersection. The specific process is described in (6) of the section (2) Orbit.

When vehicle 1 needs to pass through station 3, the process will be described in section (4) Station.

Vehicle 1 can run on straight track 2 alone; in order to improve transportation efficiency (roads that make full use of the right of way), the vehicle is organized into a virtual train 8 running on straight track 2.

Marshalling process of virtual train 8:

The virtual train according to the present invention refers to a train running at a synchronous speed by a plurality of vehicles without fixed connection and traction.

When the vehicle passes through the straight track 2, the track computer 201 sorts each car through the track wireless communication system, and numbers them. When the vehicle is running, its electronic distance measuring device 49 continuously measures the distance to the preceding vehicle, and the measurement data is sent to the measurement single-chip 403. When the distance reaches about 20 meters, the single-chip 403 sends the measured value to the main control microcomputer 401; The preceding vehicle information receiver 45 receives the information sent by the vehicle operation information transmitter 46 of the preceding vehicle. The main control microcomputer 401 operates at a speed greater than that of the preceding vehicle according to the distance from the preceding vehicle and the operating speed of the preceding vehicle. The speed difference has a linear relationship with the distance between the two cars. The speed difference is zero when the distance is zero.

Because when the distance is zero, the actual speed difference is not necessarily zero. When the following vehicle chases to the front vehicle, a collision will occur. The collision buffer device 43 is compressed, and the contact of its micro switch 439 is disconnected. The collision information is sent to the main control microcomputer 401. The main control microcomputer 401 activates the braking device of the vehicle by driving the single-chip microcomputer 404 to adjust the vehicle speed.

The front and rear vehicles 1 form a virtual train 8 running at a synchronized speed, and when passing through the bifurcation intersection 5, vehicles in different directions in the virtual train travel separately with the cooperation of the vehicle steering device 24.

For the operation of vehicle 1 in the station, see (4) Station section.

(4) Station:

The station is divided into 3 levels: small passenger station, medium passenger station, large passenger station Station.

(1) The track layout of the station:

The track layout of the small passenger station shown in Figure 9 is similar to a railway station. It has a bifurcation junction 4 at the entry station, a merge junction 5 at the exit station, and two isolated tracks in each direction of the station. One is a through track 71 for passing vehicles, and the other is a platform track 720 for getting on and off. The platform 74 is provided on the outside of the platform track. The platform thus set up is called a side platform, and the through track is arranged on the outside. Of course, it is also possible to set the platform in the middle, and such a platform is called an island platform. Each of the two track layouts has advantages and disadvantages. The straight track of the side platform is in a straight line with the straight track of the section. The straight-through vehicles are not shaken, the station expansion is easy, and the platform management is also convenient. The island platform has high platform utilization, narrow platform width, and mechanical and electrical equipment ( Escalators, air conditioners, lighting, etc.) are also fewer.

The track layout of the medium-passenger station shown in Fig. 10 is to add a passing track 73 between the through track 71 and the platform track 720, and there is no isolation fence between the platform track 72 and the passing track 73. The aforementioned vehicle signal receiver 29, track information transmitting device 30, and vehicle steering control device 24 are installed on these two tracks, as shown in FIG. 19. The vehicle drives to the designated vehicle steering control device 24 according to the dispatch instruction (the vehicle detection track information sending device 30 sends a signal and counts), and the vehicle steering control device 24 turns the vehicle from the passing track 73 to the platform track 720, or The platform track 720 moves to the passing track 73.

The track layout of the high-traffic station shown in Figure 11 is the downward direction from right to left, and the upward direction from left to left. -1 in the reference sign indicates the downward direction, and -2 indicates the upward direction. The station track is divided into two layers, the upper layer is the through track 71-1, 71-2 and the lower platform track 72-1, 72-2, and the lower layer is the passing track 73-1, 73-2 and the upper platform track 80-1. , 80-2. Section straight track 2 at the first branch 4-1 and 4-2 of the pit stop connects the straight track and shunting track 75-1 and 75-2 respectively; the straight track passes the second branch road 4-3 , 4-4 through rails 71-1, 71-2 and platform rails 72-1, 72-2 for getting off, platform rails 72-1, 72-2 for getting off, and return rails 77-1, 77- 2 connections; turn-back tracks 77-1, 77-2 are tracks from the upper level to the lower level, and are connected to the parking track or parking lot 79-2, 79-1 at the lower level; the parking track or parking lot 79-2, 79-1 respectively It is connected to the passing rails 73-2 and 73-1 in the opposite direction; the passing rails 73-2 and 73-1 are connected to the upper platform rails 80-2 and 80-1 respectively; the upper platform rails 80-2 and 80 are connected -1 is parallel to the passing rails 73-2, 73-1, there is no isolation fence between the upper platform rails 80-2, 80-1 and the passing rails 73-2, 73-1, and the vehicle lateral transfer device 78 is installed. As shown in Figure 20; the passing rails 73-2, 73-1 are connected to Departure tracks 76-2, 76-1, Departure tracks 76-2, 76-1 are the tracks from the lower level to the upper level; Departure tracks 76-2, 76-1, and through-tracks 71-2, 71-1 are at merged intersections, respectively 5-2, 5- 1 merge into straight track 2 of the interval. To facilitate the transfer of empty cars from the rear station, empty cars drive from the shunting tracks 75-1, 75-2 into the lower parking tracks 79-1, 79-2, and the passing tracks 73-1, 73-2, respectively.

(2) Setting on the station track:

The settings of the tracks, intersections and parking lot entrances at the stations are the same as those of the sections. As mentioned before. A vehicle horizontal transfer device 78 is installed between the passing track and the platform track to transfer the vehicle laterally, as shown in FIG. 20.

FIG. 17 shows a vehicle lateral transfer device 78. It is controlled by the platform track computer with an active motor 783, which drives the active roller .781 to drive the conveyor 784, which is supported by the auxiliary roller 782. The motor can be rotated clockwise and counterclockwise as required. Similar to the limit devices at both ends of the rail crane, a limit block 785 is fixed on the conveyor belt, and two limit plates 786, left and right, are fixed on the platform and the passing track, which limits the moving distance of the conveyor belt; Position board 786 is equipped with a limit switch, which is normally on. When the vehicle's lateral transfer device moves the vehicle to the position of the platform track, the limit plate contacts the limit block, which limits the movement of the conveyor belt. At the same time, the limit switch is turned off, and the motor controlled by the single-chip microcomputer stops running. When the vehicle's lateral transfer device moves the vehicle to the position of the passing track, another limit plate comes into contact with the limit block, which also limits the movement of the conveyor belt and controls the motor to stop running.

(3) Computer dispatch center of the station

A computer dispatch center is set up at the station. As shown in FIG. 23, the computer dispatch center of the station is a set of computer local area network, which includes a ticketing system 709, a station computer 702, a platform computer 703, and a dispatch computer 701. The computers in the local area network are connected through the hub 704, and the hub 704 is connected to the enterprise metropolitan area network through a dedicated communication line. The local area network also sets a vehicle distribution location database 708 and a passenger information database 707. The local area network, metropolitan area network, and database can be implemented using mature technologies of existing computer networks. The ticketing system 709 includes a manual ticketing computer 704 and an automatic ticketing computer 705.

As shown in FIG. 27: The station computer 702 and the single-chip microcomputer 705 of the platform's guide electronic sign 85, and the ticket gates 86 at each entrance control the single-chip microcomputer 706 to form a distributed control system. The hall computer 702 sends the display content of the electronic sign 85 to the single-chip microcomputer 705, and the single-chip microcomputer 705 drives the electronic sign 85. The station hall computer (702) sends the information of the destination station at the departure gate to the control single-chip 706 of the ticket gate (86). When the ticket check is correct, the ticket gate 86 is released Passengers, and pass the number of passengers to the station computer 702.

As shown in FIG. 24, the platform computer 703 and each single-chip microcomputer constitute a distributed control system. The single-chip microcomputer includes a track single-chip microcomputer 902 that manages each track, a single-chip microcomputer 202 that manages bifurcation intersections, a single-chip microcomputer 203 that manages merged intersections, and controls the movement of the lateral transmission control of vehicles MCU 901. The track single chip microcomputer 902 collects the vehicle information receiver 29 and receives the transmission signals of the vehicle information transmitter 54 of the vehicle 1, and registers and sorts the vehicles through the track wireless communication machine 210. The track single chip microcomputer 902 sends the vehicle operation information to the platform computer 703; The mobile single-chip microcomputer 901 collects the information of the vehicle entering the vehicle's lateral mobile device and the position information of the horizontal mobile device and sends it to the platform computer 703, and the platform computer 703 sends the dispatching instruction of the dispatching computer 701 to the mobile single-chip 901; Platform computer 703; Platform computer 703 sends the information of the departing vehicle to the single-chip microcomputer 203 at the intersection;

The dispatching computer 701 dispatches empty cars to the designated location, the destination station to which the designated vehicle goes, according to the travel information of the passengers in the ticketing system 709, the information of the passengers at the station computer 702, and the information of the vehicle's distribution within the station. The electronic display board guides passengers to the designated departure gates, arranges the vehicles to stop at the designated positions, and sends instructions to the vehicles; the station hall computer 702 and the platform computer 703 of the station execute the dispatch instructions of the dispatch computer 701, and The execution situation, collected information, and report to the dispatching computer 701; the dispatching computer 701 issues various dispatching instructions to the vehicle 1 through the regional wireless communication system, and the vehicle 1 sends operating information to the dispatching computer 701, applies for departure, and receives a response to the dispatching instruction Instruction

As shown in FIG. 33, the manual ticket sales computer 706 and automatic ticket sales computer 705 of the ticketing system 709 collect passenger boarding information during ticket sales. As with railways and highways, passengers need to specify a destination station and modify the passenger information in real time to the passenger information database. 707. Each ticket checking monolithic machine 706 sends the information passed by the passengers to the hall computer 702, and the hall computer 702 updates the passenger information database 707 in real time.

Vehicles in the station are registered as they enter each track. The single-chip microcomputer 902 of each track sends the vehicle position information to the platform computer 703, and the platform computer 703 updates the vehicle position database in real time. When the vehicle passes the outbound merged intersection 5, the merged single chip computer 203 sends the information of the vehicle passing to the platform computer 703. Similarly, the platform computer 703 deletes the outbound vehicle number in the vehicle location database.

(4) Wireless communication equipment at the station

Areas composed of wireless communication equipment on board the vehicle and wireless communication equipment at the station Line communication system. The regional wireless communication system is mobile data communication between the vehicle and the station LAN, and the communication coverage is the station area of the station. As shown in FIG. 28, the dispatching computer 701 is connected to the wireless communication device 710 of the station, and it forms a regional wireless communication system within the station range with the wireless communication device 411. The station wireless communication device 710 may use, for example, a duplex transceiver 710, and each of the wireless communication devices 710 has an antenna.

(V) Methods for organizing vehicle operation

Take the station shown in Figure 11 as an example. The running suffix -X indicates the running direction, X is the singular number for the downward direction, and X is the double number for the upward direction.

(1) Call the empty car:

Assumption: When there are not enough empty cars on the lower platform track 80-1, empty cars need to be called.

The station's downstream dispatching computer 701-1 queries the vehicle location database 708 of the station's local area network, and uses different dispatching schemes for different situations.

A. Call the empty car on the downward parking track: When there is an empty car on the downward parking track (parking lot) 79-1, the downward dispatch computer 701-1 directly informs the empty car on the parking track to drive to the passing track 73- through the regional wireless communication system. 1. The empty vehicle is moved to the upper platform track 80-1 by the vehicle lateral conveying device 78.

B. Calling an empty car on the upward parking track: When there is no empty car on the downward parking track 79-1, and when there is an empty car on the upward parking track 79-2, the downward scheduling computer 701-1 goes up to the upstream scheduling computer 701-2. Applying to call an empty car, the uplink dispatching computer 701-2 sends a dispatching instruction to the empty car on the parking track 79-2 through the regional wireless communication system, and the emptied car passes the front end of the passing track 73-2 and is transferred by the vehicle horizontal transmission device 78. The empty car moves to the upper platform track 80-2 and then goes to the downward parking track (parking lot) 79-1, which is the same as A afterwards. The two dispatch computers modify the vehicle location database, respectively.

C. Calling an empty car on the up and down platform track: When there is a free car on the up and down platform track 72-2, the empty car accepts the dispatching instruction from the up dispatching computer 701-2, and then from the down platform track 72- 2 Drive to the upward reversing track 77-2, enter the downward parking track (parking lot) 79-1, and thereafter, it is the same as A above. The two dispatch computers modify the vehicle distribution database.

D. Need to call empty cars from other stations: As shown in Figure 32, ① the dispatching computer 701 retrieves the vehicle dynamics database 803 of the enterprise metropolitan area network; ② sends empty cars to the rear stations that are rich in empty cars according to the principle of near by far. Dispatching application; ③ Dispatching computer 701 of the opposite station The dispatching instructions are issued through the regional wireless communication system. One vehicle is assigned to the requested station according to the vehicle's identity address. On the other hand, the platform computer 703 is notified to start the train. ④ The dispatching computer informs the dispatching computer of the applying station of the dispatching result. The dispatching computer of the station modifies the vehicle position database of the station; ⑥ The dispatching computer of the transferred vehicle modifies the vehicle dynamic database 803. ...... Vehicles call the empty station directly through the section. ... ⑦ The vehicle enters the descending shunting track 75-1 through the branching point 4-3 of the pit stop, and enters the descending parking track (parking lot) 79-1, which is the same as A above; ⑨ Call the vehicle's dispatching computer to modify Vehicle dynamic database; ⑩ Call the vehicle's dispatching computer to modify the vehicle position database. When a vehicle passes through each intersection, each intersection controls the direction of the vehicle according to the received vehicle operation information.

After the dispatch computer dispatches an empty car, it must send information such as the vehicle number of the vehicle being dispatched to the dispatch computer that requested to call the empty car; the vehicle must also be registered, checked, and sorted segment by segment during the operation. The passing intersection needs to cooperate with the control vehicle Direction of operation and so on.

(2) Departure:

Scheduling computer 701 There are two steps to organizing departures: organizing passengers to board and organizing vehicles to depart.

A. Organize passenger boarding: As shown in FIG. 33, ① the ticket sales computer 706 sends passenger information to the passenger boarding information database 707, ② the scheduling computer of the passenger boarding direction queries the passenger boarding information database 707; ③ the scheduling computer sends the vehicle to the vehicle The location database queries the empty car position; ④ After the dispatching computer designates the destination station for the empty car on the platform track, it sends the dispatching instruction to the station hall computer: the empty car position to the destination station to guide passengers to board; ⑤ station The hall's computer controls the electronic sign on the platform to indicate the empty car position to the destination station. Passengers board the car after checking the ticket through the ticket gate at the departure gate; ⑥ The station hall computer modifies the passenger's boarding information based on the ticket gate. Passenger information database; ⑦ The dispatching computer sends instructions to the platform computer to close the vehicle; ® After the vehicle leaves, the platform computer modifies the vehicle location database.

B. start vehicle: As shown in FIG. ^34, the ticket checker ① vehicle occupant determined full, hall station computer ⁷⁰² informs the scheduler can start the vehicle's computer; ② the scheduling computer sale computer station scheduling instruction, the specified vehicle departure; ③ site The computer notifies the vehicle to close the door through the track wireless communication system; or, the vehicle ’s infrared. The detector will automatically close the door when it detects that there are no passengers on the platform; ④ The platform computer designates the vehicle's lateral transport device 78 to move the vehicle to the passing track 73-1; ⑤ After the vehicle lateral transfer device 78 moves the vehicle into position, Immediately send the information of the vehicle's movement to the platform computer; ⑥ The platform computer sends the information of the vehicle's movement to the dispatch computer and applies for departure; ⑦ The dispatch computer sends the departure instructions to the vehicle through the regional wireless communication system based on the vehicle operating information of each track; ® Vehicles depart to and merge at the exit and register; 登记 Release the exit vehicle at the merge.单片机 The integrated single-chip microcomputer modifies the vehicle position database through the platform computer.

The platform computer sends the departure information to the station ’s merged intersection microcontroller. The intersection microcontroller controls according to the vehicle conditions of the two lines. If there is a through vehicle at the same time, the through vehicle is first released, and the speed of the through track 71-1 is controlled. The device runs at the running speed of the vehicle. The single-chip microcomputer at the intersection uses the speed control device to limit the speed of the starting vehicle. The single-chip microcomputer selects the driving clearance of the through-track to release the vehicle at the station.

(3) Operation: registration, chase, operation and arrival of vehicles.

Figure 35 shows: ① the dispatch computer at the departure station sends dispatch instructions to the vehicle, and the vehicle leaves the station; ② the dispatch computer at the dispatch station sends a dispatch notification to the dispatch computer at the destination station; ③ the dispatch computer at the dispatch station modifies the vehicle dynamic database 803 ④ The vehicle enters the section track, and the vehicle 1 registers, checks and sorts with the track computer 201; ...

On the straight track, the vehicle chases the preceding vehicle. When the electronic distance measuring device detects that the vehicle distance is less than the threshold, the vehicle information receiver of the following vehicle can receive the vehicle operation information sent by the vehicle information transmitter of the preceding vehicle. The vehicle automatically forms a virtual train.

The realization of virtual trains uses vehicle chasing technology, which involves devices such as electronic ranging equipment, vehicle information receivers, vehicle information transmitters, collision buffers, and proximity collision sensors installed on vehicles. The specific steps are:

□ Ranging: The electronic distance measuring device installed on the front of the vehicle continuously measures the distance from the vehicle in front of the vehicle. The main control microcomputer of the vehicle controls the speed of the vehicle according to the distance. When the distance is greater than the threshold, the vehicle is designated by the track computer. Speed running

□ Chase: When the distance is less than the threshold, the vehicle information receiver of the following vehicle can receive the vehicle operation information of the preceding vehicle, and the main control microcomputer controls the vehicle to chase at a speed greater than the preceding vehicle according to the speed of the preceding vehicle. The speed difference between the two vehicles has a linear relationship with the distance between the vehicles. If the distance between the vehicles is close to zero, the difference in the speed of the vehicles is also close to zero.

Virtual train operation: When the vehicle distance is close to zero and the collision occurs, the vehicle's collision buffer device plays a buffering role. The micro switch provides collision information to the main control microcomputer. Reduce the speed of the vehicle until it is out of the collision; the rear vehicle continuously adjusts the speed until the speed of the two vehicles is synchronized. By analogy, the vehicles constitute a virtual train running in the section, which improves the transportation capacity.

When a vehicle needs to pass through the station, registration and verification are performed after passing through the fork in the station. The single-chip microcomputer at the fork controls the vehicle's steering control device to stop running, and the vehicle continues to go straight on the through track. The vehicle then enters the through track and performs registration, verification, and sequencing; the through track computer sends the vehicle's operating information to the microcontroller at the exit of the merged station; the vehicle runs at the speed specified by the through track computer or reconstitutes a virtual train. The vehicle then passes through the exit junction of the station and enters the straight track.

Still in Figure 35 ⑤ When the vehicle reached the branch station 4-1 of the destination station, registration and verification were performed; ⑥ The single-chip computer at the branch station 4-1 stopped the vehicle's steering control device; the vehicle went straight to the branch station 4- 3, and at the intersection 4-3, turn the vehicle into the fork and get off the platform track 72-1; the vehicle travels to the forefront of the platform track 72-1 (when a vehicle is parked on the front side, the vehicle automatically adjusts the speed and stops Behind the front car); 后 After parking, the vehicle applies to the station's downlink dispatch computer for opening the door through the regional wireless communication system; ® When the downlink dispatch computer determines that the vehicle does not need to move forward, it notifies the vehicle and the platform computer that the vehicle can open the door and exit Passengers; vehicles automatically open doors and broadcast prompt passengers to get off. When the sensor inside the vehicle determines that there are no passengers, the vehicle closes the door automatically.下行 The downlink dispatching computer modifies the vehicle location database; ⑩ The downlink dispatching computer modifies the vehicle dynamics database of the enterprise metropolitan area network.

(4) Empty car arrangement:

After the empty car is closed, the empty car applies to the downward dispatch computer for arrangement.

If the empty car is parked in the parking lot 79-2: The downward dispatching computer informs the upward dispatching computer of the information of dispatching the vehicle to the parking lot 79-2; the downward dispatching computer instructs the empty car to the parking track (parking lot) 79-2, and the vehicle will Drive through the return track 77-1 to the parking track (parking lot) 79-2. After the vehicle is parked, it is registered with the computer on the parking track (parking ground) 79-2 via the track wireless communication system. The downlink dispatching computer modifies the vehicle distribution location database.

If an empty car is parked in parking lot 79-1: The downward dispatch computer notifies the upward dispatch computer of the information of dispatching the vehicle to parking lot 79-1; the downward dispatch computer instructs the empty car to the parking track (parking lot) 79-1, and the vehicle will run parking bound by folded rail track 77-1 (parking) 79-2; 73-2 then track bound traffic, by the vehicle to the vehicle transfer means stop track ^80- on the outlet (FIG. 18) ^2, the vehicle Apply to the uplink scheduling computer to start up The dispatch computer instructs the vehicle to start driving to the parking track (parking lot) 79-1. The downlink dispatch computer modifies the vehicle distribution location database.

If an empty car is parked on the upper platform track 80-1: The first step is to park the car in parking lot 79-1 (the process described above); the second step is to move the empty car in parking lot 79-1 up Platform track 80-1. The second step is that the dispatching computer transmits the dispatching instructions through the track computer of the parking lot 79-1. The orbiting computer of the parking lot 79-1 transmits the dispatching instructions to the vehicle through the track wireless communication system.
