Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a railway security system that controls a train using an interlocking device and a ground ATC device, and more particularly, to a transmission connection between the interlocking device and the ground ATC device.
[0002]
[Prior art]
FIG. 4 shows the relationship of information transmission between the conventional interlocking device and the ATC ground device. The interlocking device 1 is installed in a (interlocking) station, receives the status of the station intermediate track circuit (falling / flooring), approach information (AR), etc. from a plurality of ground ATC devices 2, and receives on-site equipment (switches, The control content is output to a traffic light or the like. In consideration of train safety, the interlocking device has a multiple system configuration. The ATC ground device 2 receives information on the state of the field equipment (opening direction of the switch, etc.), the approach locking relay (ASR), etc. from the plurality of interlocking devices 1 and sends it to the ground unit installed under the track. It outputs the speed limit of the train.
[0003]
The interlocking device 1 and the ATC ground device 2 perform control in their respective control ranges. A boundary line 41 indicates a control boundary of the interlocking device 1, and a boundary line 42 indicates a control boundary of the ATC ground device 2.
[0004]
[Problems to be solved by the invention]
However, in the above prior art, the control range of the interlocking device 1 and the control range of the ATC ground device 2 are different. Therefore, since outputs from a plurality of interlocking devices are input to one ATC ground device, or outputs from a plurality of ATC ground devices are input to one interlocking device, each device has necessary information and is unnecessary. It is necessary to provide each device with a process for identifying information and (whether it is information within the control range of the input side device).
[0005]
Accordingly, an object of the present invention is to provide a railroad security system that does not require a process for identifying the necessary information and unnecessary information and that improves the processing speed.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, in a railway security system that controls a train using a plurality of interlocking devices and a plurality of ATC ground devices provided in an ATC line section, each control range and a plurality of interlocking devices are controlled . The control range of each ATC ground device is the same, and the number of interlocking devices in the ATC line section and the number of installed ATC ground devices are the same. One-to-one correspondence is established by transmission lines, and each of the plurality of interlocking devices and the plurality of ATC ground devices does not need to identify whether input information is within the control range.
As a result, information can be transmitted and received between the interlocking device and the ATC ground device with one transmission line, so that the input information is identified (determines whether the information is within the control range of the input side device). Is no longer necessary.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to FIGS.
[0008]
FIG. 1 is a diagram showing the relationship between an interlocking device in an ATC line section and an ATC ground device in the present embodiment.
[0009]
A control boundary between the interlocking device 1 and the ATC ground device 2 is indicated by a boundary line 11. The number of installed interlocking devices 1 and ATC grounding devices 2 in the ATC line section is the same so that the control range of the interlocking device 1 and the ATC grounding device is the same. As a result, transmission between the interlocking device 1 and the ATC ground device 2 can be performed in a one-to-one correspondence, and each device of the interlocking device 1 and the ATC ground device does not need to identify the transmitted information. became. The processing speed can be improved as much as this processing is unnecessary.
[0010]
FIG. 2 illustrates a second embodiment of the present invention.
[0011]
If the control range of the interlocking device 1 and the ATC ground device is the same as in the above embodiment, the interlocking device and the ground ATC device can correspond one-to-one, so as shown in FIG. It is possible to integrate the ground ATC device.
[0012]
The interlocking / ATC ground device 3 exchanges information such as the state of the track circuit falling / climbing within the control range of the own device, the blockage that can be entered, and the like with an adjacent device.
[0013]
FIG. 3 is a block diagram showing an internal configuration of the integrated interlocking / ATC ground device. 31 is a control instruction information input unit for inputting a request to a control target device such as a course setting output from a host computer (ex. Center), a switch alone switch, and 32 sends a specific signal to the track circuit. , A train detection unit that determines whether the track circuit has fallen or climbed according to the signal, 33 is a control target device state information input unit that inputs a control target state such as a switch opening direction, a traffic signal display, and the like. Control information for the control target is defined from the control instruction information input by the control instruction information input unit 31, the control target state information input by the control target device state information input unit 33, and ATC information from the ATC information storage unit 37 described later. An interlock control unit that calculates and creates based on the generated logic, 35 is a control information output unit that outputs control information created by the interlock control unit 34 to a control target, and 36 is a control created by the interlock control unit 34. Information and the interlocking information storage unit that stores the control target state information input from the control target device state information input unit 33, 38 is the train detection information determined by the train detection unit 32 and the interlocking information from the interlocking information storage unit 36, And an ATC information creation unit that calculates and creates ATC information of the self-control range based on adjacent ATC information from an adjacent ATC information input / output unit 40, which will be described later, and ATC information that stores ATC information created by the ATC information creation unit 38 The storage unit 39 converts the ATC information created by the ATC information creation unit 38 into a signal and outputs it, and 40 inputs the ATC information created by the adjacent interlocking / ATC ground device 3. It is an adjacent ATC information input / output unit that outputs the ATC information created by the information creation unit 38 to the adjacent interlocking / ATC ground device 3.
[0014]
A request from the control instruction information input unit 31 such as setting a course from a host computer to a control target, and a single switch of the switch as control instruction information is acquired, and the acquired control instruction information and control target device state information input unit 33 are acquired. Based on the control target state information such as the opening direction of the switch and the current state of the traffic light, and the ATC information such as the approach information (AR) stored in the ATC information storage unit 37, the interlock control unit 34 determines the control range. Control information such as approach lock information (ASR) for the control target is created, and the control information is output from the control information output unit 35 to the control target. Further, the control information created by the interlock control unit 34 and the control target state information input from the control target device state information input unit 33 are stored in the interlock information storage unit 36.
