Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic train control device (hereinafter, referred to as an ATC device), and more particularly, to a driving system using an existing ground signal and a driving system using an in-vehicle signal. To an ATC device that can be switched to the ATC device. 2. Description of the Related Art An ATC system transmits permissible operating speed information from the ground to a vehicle for each closed section in accordance with the distance from a preceding train and the state of route opening, and checks the train speed on the vehicle. And the deceleration control is automatically performed so that the train speed becomes equal to or lower than the allowable speed. [0003] A conventional ATC device adopting an operation system using a ground signal will be described with reference to FIG. In the figure, each closed section 1T, 3T, 5 of the track 1
At the entrance side of T, 7T, each closed section 1T, 3T, 5T,
Traffic lights 2a to 2d indicating the opening status of 7T are installed. The appearance of these traffic lights 2a to 2d is controlled by the corresponding signal control units 3a to 3d.
The signal control units 3a to 3d correspond to a transmission function of transmitting a track current (including permissible speed information) from the exit side (train traveling direction side) of the rear block section to the track of the rear block section. A receiving function is provided for receiving track current flowing in the track at the entrance side (the direction opposite to the train traveling direction) of the closed section. For example, the signal control unit 3d transmits the orbital current to the trajectory of the rear blockage section 5T and receives the trajectory current through the corresponding trajectory of the blockage section 7T. Further, the signal control units 3a to 3d operate the internal track relay according to the reception state of the track current to control the R, Y, and G indications of the corresponding traffic signals 2a to 2d. Furthermore, a local signal of a commercial frequency having a phase of 0 ° is input to each of the signal control units 3a to 3d, and the level and the phase of the received orbital current are compared with the local signal. [0004] For example, when the train 4 exists in the closed section 7T, the track current transmitted from the signal control unit 3e is short-circuited by the wheels of the train 4 and is not received by the signal control unit 3d, so that the signal control unit 3d does not receive the track current. The track relay in the unit 3d falls. The signal 2d corresponding to the signal control unit 3d becomes the R display by the drop operation of the track relay. Then, since the orbital current is not received, the signal control unit 3d performs a reversal operation of inverting the phase of the orbital current to be transmitted by 180 ° with respect to the phase of the local signal. To transmit the orbital current inverted by 180 °. Therefore, the signal control unit 3c
Receives the orbital current 180 ° out of phase, which causes the orbital relay to be inverted and the corresponding traffic light 2c
Is the Y presentation. The signal control unit 3c transmits an orbital current having an in-phase of 0 ° to the local signal to the closed section 3T,
In the signal control unit 3b, the orbital current is received, and the orbital relay is localized, and the corresponding traffic light 2b is set to the G display. The signal control unit 3b also transmits an orbital current having a phase of 0 ° to the closed section 1T, and the signal control unit 3a receives this orbital current, the orbital relay is localized, and the corresponding traffic light 2a is indicated as G. The track current transmitted from each of the signal control units 3a to 3d to the track 1 includes permissible speed information corresponding to the position of the train 4, and the rear train that has entered these closed sections 1T, 3T, and 5T. Receives the track current flowing through the track 1 via the upper armature, and automatically executes the deceleration control to control the train speed to be equal to or lower than the allowable speed according to the allowable speed information of the received ATC signal. [0005] By the way, the conventional AT
In the C device, as described above, the indication of the ground traffic signals 2a to 2d is controlled according to the position of the train ahead, and the driver employs an operation system based on the ground traffic signal that operates according to the indication of the traffic signal ahead. ing. However, in recent years, the speed of trains has been increased, and when the train speed increases, in the case of an existing driving system using ground traffic lights, in snowy countries, etc., when the amount of snowfall increases, the traffic lights become difficult to see or There is a possibility that the traffic light may be mistaken for the traffic light on the own track. As a countermeasure against such a high-speed vehicle, it is considered that a driving system using an in-vehicle traffic light in which a traffic light is provided in a driver seat is effective. However, in consideration of the fact that conventional general vehicles that are slower than high-speed vehicles can secure sufficient safety even with the existing ground signal driving system, it is economically burdensome to adopt the onboard signal system for all trains. Because of its large size, in a line section in which a high-speed car and a general car are operated together, there is a demand for a combined system of an operation system using an in-car signal and an operation system using a ground signal. [0007] When operating a train, it is obligatory to operate by using either a ground signal or an in-car signal. In the operation according to the ground signal system,
It is necessary to stop the in-vehicle signal system and conversely, to stop the ground signal system in the operation according to the in-vehicle signal system. The present invention has been made in view of the above circumstances,
The in-car signal system works for high-speed vehicles, and the ground signal system works for ordinary vehicles.
An object is to provide a TC device. [0008] Therefore, in the present invention,
Based on the position information of the front train in the continuous block section, the ATC signal specifying the permissible speed is transmitted to the train in each block section behind the block section in which the train is located, and at the entrance side of each block section. An ATC device configured to control the indication of an installed ground traffic signal, comprising: a transmission unit that transmits a train detection signal to a pair of tracks in the closed section at an exit side of the closed section; Receiving means for receiving the train detection signal via the pair of tracks,
Signal control means for controlling the indication of the traffic signal in accordance with the reception state of the train detection signal of the receiving means. Each information transmission means for performing transmission, and transmission position switching means for switching the transmission position of the train detection signal from the transmission means to the closed section entrance side, the information transmission means, from the train entering the closed section Trains are onboard signals
Traffic signal information indicating a high-speed vehicle transmits a flashing lamp information of each traffic signal in the signal control means to occlusion section in which there is maximum train of front block sections when input through the ground coil with a Light-extinguishing information transmitting means, train position information transmitting means for transmitting train position information to each information transmitting means in each closed section behind the closed section in which the train is present based on the train detection information, Transmission position switching control output transmission means for transmitting a control output to the transmission position switching means to switch the transmission position of the transmission means to the entrance side of the closed section only in the closed section immediately after the closed section in which the train is present, based on the information; a structure having an interior <br/> traffic when a train detection signal through said pair of bearing received in a car upper and G current view, the interior traffic and R current-when no reception configuration It was. In the above configuration of the present invention, when a train enters a closed section, information on whether a high-speed car or a general car is on the vehicle is transmitted to the information transmission means on the ground via the ground rail. When the vehicle is a high-speed vehicle, the information transmitting means transmits the ground signal extinguishing light information to the information transmitting means in the front side closed section. This information is transmitted up to the closed section where the preceding train exists. As a result, all the ground traffic lights up to the entrance of the closed section where the train in front is present are extinguished, and a driving system based on the on-board traffic lights is formed. Further, the information transmission means transmits the train position information to the closed section on the rear side. Then, in the closed section immediately after the closed section in which the train is present based on the train position information transmitted from the information transmitting means, the transmission position switching means switches the transmission position of the track current from the exit side to the entrance side of the closed section. . [0010] Thus, in the case of a high-speed car, if the vehicle enters a closed section immediately after the closed section where the train in front exists,
In the closed section before entry, the track current was forward-transmitted (transmitting state from the closed section exit side) and received on the vehicle and the in-vehicle signal was indicated by G, whereas the track current was in the reverse transmitting state. The track current is not received by the upper armature located in front of the wheel due to the wheel short circuit, and the indication of the in-car signal changes from the G indication to the R indication. Further, the service brake and the emergency brake are automatically selected based on the information on the position of the front train and the position of the own train transmitted to the upper side of the vehicle via the ground child, and the deceleration control is executed. On the other hand, when the train that has entered the closed section is a general car, no light-extinguishing information of the ground signal is transmitted, and
The transmission position of the orbital current is not switched, and the terrestrial traffic signal is controlled based on the trajectory relay operating state, as in the conventional case, and an operation system using the terrestrial traffic light is obtained. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of an ATC device according to the present invention. The same parts as those in the related art are denoted by the same reference numerals, and description thereof is omitted. In FIG. 1, each closed section 1T, 3T, 5
At the entrance side of T and 7T, ground children 11a, 11b, 11c and 11d are installed. These ground children 11a, 11b, 11c, 11d
Transponder bodies 12a, 12b as information transmission means,
12c and 12d, respectively, and bidirectional transmission is performed between the transponder main bodies 12a, 12b, 12c and 12d. Each of the transponder bodies 12a, 12b, 12
In c and 12d, when a high-speed vehicle equipped with an in- vehicle signal enters a closed section, high-speed vehicle information is received from above the vehicle, and light-extinguishing information of the ground signal is transmitted to the transponder main body of each forward closed section. . This light extinguishing information is transmitted to the closed section where the forward train exists. The train position information input from the signal control units 13a, 13b, 13c, and 13d, which will be described later, is transmitted to the transponder main body in each closed section behind. Further, the transponder bodies 12a, 12b, 12
c and 12d transmit the signal extinguishing light information to the corresponding signal control units 13a, 13b, 13c and 13d, and reversely transmit the orbital current of the block section immediately after the block section where the train exists (block section entrance side). The transmission position switching control information is transmitted to the corresponding signal control unit. Therefore, each of the transponder bodies 12a, 12b, 12c and 12d as information transmitting means has the functions of a signal extinguishing light information transmitting means, a train position information transmitting means and a transmission position switching control output transmitting means. . On the other hand, the signal control units 13a, 13b, 13c, and 13d, when the reverse transmission information is input by the transmission position switching control information from the transponder bodies 12a, 12b, 12c, and 12d, change the transmission position of the orbital current in the closed section. On the entrance side, a transmission / reception position switching mechanism of a transmitter as a transmission unit and a receiver as a reception unit is provided so that the reception position can be switched and set to the exit side of the closed section, respectively. It has the function of means. Further, the corresponding traffic lights 2a, 2b, 2c, 2d are extinguished by inputting the extinguishing information. Furthermore, as in the past, localization is performed according to the orbital current reception state,
It is equipped with a track relay for taking the operational state of inversion and falling (bra) and generating a ground signal control output and a train detection output in the case of a general vehicle. Next, the operation of this embodiment will be described with reference to FIGS. For example, a case where the train 4 exists in the closed section 7T will be described. In this case, the track current transmitted from the signal control unit 13e is short-circuited by the wheels of the train 4, is not received by the signal control unit 13d, and the track relay in the signal control unit 13d falls, corresponding to the signal control unit 13d. Traffic light 2d becomes R indication,
Prohibit the rear train from entering the closed section 7T. When there is no high-speed vehicle behind, an operation system using a ground traffic signal is performed by the same operation as in the past, and the traffic signals 2a to 2d are followed. That is, since the orbital current is not received, the signal control unit 13d performs a reversing operation to invert the phase of the orbital current to be transmitted by 180 ° with respect to the phase of the local signal. The orbital current inverted by 180 ° is transmitted. The signal control unit 13c receives the orbital current inverted by 180 °, the orbital relay is inverted, and the corresponding traffic light 2c is set to the Y display. Signal control unit 13c
Transmits an orbital current having the same phase as that of the local signal and having a phase of 0 ° to the closed section 3T, and the signal control unit 13b receives the orbital current, and the orbital relay is localized, so that the signal 2b is displayed as G. The signal control unit 13b also has a phase of 0 °
The orbital current in the closed section 1T and the signal control unit
13a receives this orbital current, the orbital relay is located, and the corresponding traffic light 2a is set to the G display. The train position information indicating that a train is present in the closed section 7T is transmitted from the transponder main body 12d to the transponders 12a to 12c at the rear. On the other hand, when the following train is a high-speed car, for example, when the following high-speed car enters the closed section 1T, the high-speed car having an in- car signal from above the car via the ground child 11a provided at the entrance side of the closed section 1T. Is transmitted to the transponder main body 12a. Based on the high-speed vehicle information, the transponder main body 12a transmits the ground traffic signals 2b to
Each transponder body 12b ~ corresponding to the 2d light extinguishing information
Transmit up to 12d. Each transponder body 12b-12d
Transmits this extinguishing information to the corresponding signal control units 13b to 13d, and the signal control units 2b to 2d extinguish the corresponding traffic lights 2b to 2d. Similarly, the high-speed vehicle information is transmitted to the signal control units 13b to 13d via the transponder main bodies 12b to 12d ahead, and a train exists in the closed section 7T according to the train position information from the transponder main body 12d in the closed section 7T. Therefore, regarding the block section 5T immediately after that, the transmission position of the orbital current is set to the block section 5T.
The reception position is switched to the entrance side of T and the exit position of the closed section 5T, respectively, and the orbital current is set to the reverse transmission state. in this way,
Closed sections 3T, 5T where trains exist from the front of the high-speed car ,
Until 7T , the ground traffic light is extinguished, and the track current in the closed section 5T immediately after the closed section 7T where the train in front is present is switched to reverse transmission, whereby an operation system using an in-car signal is provided. In the driving system using such an in-vehicle signal, in the closed sections 1T and 3T in which the track current is in the forward transmission state as shown in FIG.
When the vehicle enters T and 3T, the track current is received on the upper side of the vehicle, so that the in-vehicle traffic signal is displayed as G, and an ATC signal (a signal indicating an allowable speed) according to the position of the train 4 ahead is transmitted to each ground vehicle. The vehicle travels at a speed less than the specified permissible speed received from 11b and 11c. When the track current enters the closed section 5T in the reverse transmission state, the track current cannot be received on the upper side of the vehicle due to the short-circuit of the wheel, and the in-vehicle signal indicates R. Further, since a train exists in the closed section 7T based on the train position information ahead, the service brake is selected and operated based on the brake selection information transmitted from the transponder main body 12c to the vehicle via the ground child 11c. When the vehicle enters the closed section 7T where the train 4 is present, the brake selection information indicates that the emergency brake is selected, and the emergency brake operates. That is, as shown in FIG. 3, it is determined whether or not the track current is being received. When the track current is being received, the track current is in a forward transmission state and there is no other train in the same closed section. The speed control is performed based on the permissible speed information from the main body, and the in-vehicle traffic light is changed to the G display. On the other hand, when the track current is not received, the track current is in the reverse transmission state or when there is another train in the same block section, and based on the brake selection information from the transponder main body, the block section in which the other train exists is selected. In the blockage section immediately after, the service brake is selected and the in-vehicle signal is indicated by R, and when entering the blockage section where another train exists, the emergency brake is selected and the in-car signal is set to the blockage section 5.
As in the case of T, it becomes R presentation. According to such a configuration, it is possible to operate only the high-speed car by the driving system using the in-vehicle traffic signal by using the existing driving system using the ground traffic light. Therefore, the equipment becomes much cheaper, safety for general vehicles can be ensured, and safety for high-speed vehicles can be improved. As described above, according to the first aspect of the present invention, a driving system using an in-vehicle traffic light can be installed together with an existing driving system using a ground traffic light, and a general vehicle is a ground traffic light system. Since high-speed cars can be operated using the on-board signal system, the equipment is much cheaper and more economical than when all trains are on-board signal systems, and safety for general cars is ensured. It is possible to improve safety for high-speed vehicles.
