Description

Method for preventing rail train collision

The present invention relates to a method of preventing collisions, and more particularly to a method of preventing collision of a rail train.

The train travels on the track, and if there is no collision, it will cause great damage. However, there is currently no good preventive mechanism to prevent rail train collisions.

It is an object of the present invention to provide a method of preventing collision of a rail train.

To achieve the above object, the method for preventing collision of a rail train of the present invention comprises: installing a controller on each of the two trains to control the speed of the train to which the train belongs, wherein the two trains are respectively the first train and the second train; setting a server The server establishes a protection area in front of each of the trains according to the weight of each train and the position and speed on the track; and when the guard areas of the two trains overlap, the server system Let the two controllers control the train to decelerate.

According to the method for preventing collision of a rail train according to the present invention, when the guard areas established in front of the two trains overlap, the servo causes the two trains to start the anti-collision mechanism to decelerate the vehicle and prevent the collision from occurring.

The above and other objects, features, and advantages of the present invention will become more apparent from the embodiments of the invention.

The method for preventing collision of a rail train of the present invention first determines the position of the train on the track and the speed and direction of the train. Referring to Fig. 1, there is shown a system diagram of an apparatus for preventing collision of a rail train of the present invention. A radio frequency identification reader (RFID Reader) 110 is mounted beside the track switch 190, and a plurality of wireless signal transceiving devices 120 are mounted adjacent to the track. The aforementioned radio frequency identification reader 110 and wireless signal transceiving device 120 can be connected to a server 170 by wire or wirelessly. When the RFID reader 110 and the wireless signal transceiver 120 are connected to the server 170 by wire, the network route can be used for connection, and the hub 180 can also be utilized to make the network wiring easier. In addition, the switch 190 is electrically connected to the server 170 and can transmit its forward and reverse signals to the server 170.

According to the method of the present invention for preventing collision of a rail train, a radio frequency identification tag (RFID Tag) is mounted on the train to be able to position the train on the track. In detail, one or more radio frequency identification tags 160 are mounted on the outer side of each train 195, wherein the radio frequency identification tags 160 can be active or passive radio frequency identification tags, preferably passive radio frequency identification tags. label. When a plurality of radio frequency identification tags 160 are installed, they can be respectively installed on the left front side, the right front side, the left rear side or the right rear side of the train 195, and avoid the bad environment, so as not to affect the reading effect.

In addition, on the train 195, for example, a vehicle having electric power and power output is mounted with a controller 151, which can read the driving information of the train, wherein the driving information can include the travel of the vehicle. Information such as gear position (forward, backward or stop), speed and distance traveled. In addition, a wireless signal transmitting and receiving device 152 is further mounted on the vehicle, and is connected to the controller 151. The wireless signal transmitting and receiving device 152 can wirelessly throw out the train driving information read by the controller 151. The wireless signal transmitting and receiving device 120 disposed on the ground can receive the information thrown from the wireless signal transmitting and receiving device 152 and transmit it to the server 170.

According to the method of preventing collision of a rail train of the present invention, the forward and reverse signals of the switch 190 are transmitted to the servo 170. When a train 195 passes through the switch 190, the operational radio wave data transmitted by the RFID reader 110 can thus be received by the passive radio frequency identification tag 160 on the train 195, the radio frequency identification tag 160 The received electric wave is converted into energy to drive an identification wafer (not shown) inside thereof. After the identification chip is driven, the RFID tag 160 transmits radio wave data containing the identification chip information. If the radio frequency identification tag 160 on the train 195 is active, it will actively transmit radio wave data containing the internally identified wafer information. After receiving the radio wave data from the radio frequency identification tag 160, the radio frequency identification reader 110 transmits it to the server 170, and the server 170 identifies which radio frequency identification tag 160 is transmitting the signal. Since the time when the radio frequency identification reader 110 receives the radio wave data is known, and the information on which train 195 the radio frequency identification tag 160 is mounted on the server 170 is recorded, it is known which one is located. Train 195 passes through the switch and the time it takes to pass the switch.

According to the method for preventing collision of a rail train according to the present invention, since the forward and reverse signals of the switch 190 have been previously transmitted to the servo 170, it can be determined on which route the train 195 will travel after passing through the switch. Since the wireless signal transmitting and receiving device 152 continuously throws out the instant driving information representing the train 195 to the server 170, and the information such as the length and the geographical position of each track is also recorded in the server 170 in advance, the radio frequency identification reading is known. The time when the radio 110 receives the radio wave data, that is, the time when the train 195 passes through the switch 190, and uses the information such as the instantaneous vehicle speed and the walking distance contained in the driving information, can calculate the current position of the train 195 on the track. . It should be understood that the current speed of the train 195 can be obtained by converting the rotational speed of the measuring wheel, and the distance that the train 195 has traveled can be calculated from the wheel speed and the travel time. Since the method of calculating the speed of the train and the distance of the travel is well known and is not the focus of the present invention, it will not be further described.

According to the method of the present invention for preventing collision of a rail train, information of each track and its upper switch 190 can be recorded in advance in the server 170, and information of the radio frequency identification reader 110 disposed beside each switch 190 is also It is recorded in the server 170 in advance. In addition, the information of which train 195 is represented by each radio frequency identification tag 160 has also been recorded in the server 170. Therefore, the present invention can use the method disclosed above to calculate which position on each track the train is currently on.

When the position of the trains on the track and the driving speed are confirmed, the protection zones of each train can be established according to the position and speed of each train on the track. In detail, in order to avoid collision of the train, the servo 170 of FIG. 1 establishes a guard zone for each train in front of its traveling direction according to the weight of each train and the section, position and speed on the track. When the total weight of the train is larger, the required protection area is also larger; when the speed of the train is larger, the required protection area is also larger. In general, the guard zone indicates the brake distance required for the train to completely stop. The more the number of trains (the number of cars), the more we can understand that the braking distance of the train will be larger, so the built-up protection area will be larger. When the train contains only one organ vehicle and no car is hung, only one car will have a smaller stopping distance, and thus the established protective zone is smaller. In addition, when the train has a load, it will be larger than the braking stop distance required for the train without the load, so the established protection area will be larger. When the speed of the train is larger, the stopping distance required for the train that is smaller than the speed is larger, and thus the established protection area is also larger.

Referring to Figure 2, there are shown trains 211, 212 and train 221 traveling on a tree-like track network. The trains 211, 212, and 221 are the same as the train 195 of Fig. 1, and the radio frequency identification tag 160 (not shown) of Fig. 1 is also mounted on the outer side thereof, and also on the carts 211 and 221, Fig. 1 is also installed. Controller 151 and wireless signal transceiver 152 (not shown). The radio frequency identification tag 160 on the trains 211, 212, 221 also transmits radio wave data containing the internal identification chip information to the radio frequency identification reader 110 for transmission to the server 170 via the network. The controller 151 on the vehicle bodies 211 and 221 can also read the driving information of the train, and wirelessly throw the train driving information read by the controller 151 to the wireless device set on the ground through the wireless signal transmitting and receiving device 152. The signal transceiving device 120 receives and transmits to the server 170 via the network.

When the train 211 pulls the train 212 to the left on the track, the server 170 in FIG. 1 can establish a fan-shaped protection in front of the direction of travel of the train 211 according to the position and speed of the first train 211 on the track. Zone 250, which covers several sections of track and several switches. When the train 211 travels on the track provided with the switch in front, depending on whether the switch is in the upright position or the reverse position, it is possible to walk on the ortho-track or the reverse track after passing through the switch. Therefore, the track system covered by the protected area 250 indicates that the train 211 is likely to pass for the next period of time. Similarly, when the train 221 travels to the right on the track, the server 170 in FIG. 1 also establishes a sector-shaped protection area 260 in front of the direction of travel of the train 221 according to the position and speed of the train 221 on the track. . The track system covered by the guard zone 260 indicates that the train 221 is likely to pass for the next period of time.

When the trains 211, 221 move on the track, their respective protection areas 250, 260 will also move on the track, and the size of the protection areas 250, 260 will also follow the sections, positions and positions of the trains 211, 221 on the track. Change in speed. When the protection areas 250, 260 move to overlap, it means that the trains 211, 221 are likely to collide. At this time, the servo 170 that establishes the protection areas 250, 260 for the trains 211, 221 will start the defense for the trains 211, 221 Hit the mechanism. In detail, the server 170 transmits wireless signals to the wireless signal transmitting and receiving means 152 on the vehicle bodies 211, 221 via the wireless signal transmitting and receiving means 120 via the network. After the controller 151 receives the signal transmitted from the wireless signal transmitting and receiving device 152, the control vehicle 211, 221 brakes the vehicle and decelerates, and the train 211, 212 and the train 221 have no chance to collide. At the same time, the controller 151 also generates an alarm signal to alert the person who controls the travel of the trains 211, 221.
