Description

The present invention relates to a train control system, a train control method, and a ground control device.
More specifically, when a train travels in a section where control ranges of a plurality of different railway signal systems overlap, for example, a system that performs train control such as brake control according to any one of the railway signal systems, a train control method , Relating to ground control equipment.

Trains are operated according to a security system that determines the permissible speed of each train. The security system includes, for example, ATC (Automatic Train Control), ATS (Automatic Train Stop system), etc., which are usually called railway signal systems.
Here, when a train travels in a section in which two different railway signal systems are continuous, there is an overlapping section in which the train can receive signals of any railway signal system. In this overlapping section, it is necessary to switch the railway signal system at an appropriate timing.
As a means of switching the railway signal system, when a signal of another railway signal system different from the railway signal system that has been adopted is received, a method of switching to another railway signal system newly received at that time, and the railway signal system There is a method in which a transponder that means switching is previously installed and the railway signal system is switched when a train passes over the transponder, that is, when the train reaches a certain point.
By switching the railway signal system in this way, it becomes possible to automatically switch the railway signal system at an appropriate timing.

However, in all of the conventional technologies described above, the railway signal system is switched when the train reaches a certain point, so when there is no need for switching, that is, signals of a plurality of railway signal systems are received. Even in the possible overlapping section, there is a disadvantage that the railway signal system is forcibly switched.
As a system for correcting this inconvenience, for example, there is JP-A-2002-240715 (Patent Document 1). In this publication, in a safety system selection system including a route information storage unit, a signal system determination unit, and a signal system selection device, “the ground control device has a range of a track circuit signal system and a range of a radio signal system” When the track overlaps the section where the train stops, the range of the signal system to which the stop limit of the train belongs is determined and this information is transmitted to the on-board controller. ”“ The on-board controller is the signal system to which the stop limit of the train belongs. The speed control is performed according to ".

JP 2002-240715 A

  According to the security system selection system described in Patent Literature 1, it is possible to automatically switch the security system followed by the train at an appropriate timing, and to perform the switching safely.

However, it does not take into account the determination of the railway signal system in the case where there are a plurality of railway signal systems adopted by the route at the timing intended by the ground side device.
More specifically, in Patent Document 1, for example, the train travels from the track circuit signal control range to the radio signal system A control range, and the train can receive the track circuit signal control range and the radio signal system A. When the train is on the line, the radio signal system A in the radio signal system A control range adopted by the route is identified based on the train position information and route information, and the train is automatically controlled by the radio signal system A. To switch to
In the section where the train is present, when there is an overlapping section where signals of a plurality of radio signal systems A and B can be received, it has not been possible to determine whether the radio signal system is A or B.
That is, when there are a plurality of railway signal systems adopted by the route, there is a problem that the railway signal system that the train follows cannot be determined.

Therefore, an object of the present invention is to provide a technique for appropriately switching the security system that a train follows even when there are a plurality of railway signal systems adopted by the route.
For example, a train travels from a track circuit signal control range to a control range of a plurality of train control systems (wireless signal systems A and B), and the train receives signals of a plurality of radio signal systems A and B and track circuit signal systems. When staying in a possible overlapping section,
From the ground control device, a switching signal for instructing switching of the wireless control method based on the train route information and a signal for specifying the wireless control method as A or B are transmitted to the on-board control device, and the switching signal and the designation Train control based on the wireless control method A or B,
Even when there are a plurality of radio signal systems A and B adopted by the route, when the switching signal is received and the signal of the train control system is the radio signal system A, the train control is performed by the radio signal system A. In the case of signal system B, train control is switched and controlled by radio signal system B.
If the train control signal cannot be received, train control is performed using the track circuit signal before switching,
In the section where the train is located, even if it is in the overlapping section where signals of multiple radio signal systems A and B and track circuit signal system can be received, it can be switched at the timing that the ground device side intended. is there.

In order to solve the above problems, one of representative train control systems, control methods, and ground control devices of the present invention is:
In the train control system that transmits and receives the train information including the train position information and the control information for controlling the train between the ground device including the ground control device and the on-board device including the on-board control device,
The ground control device is:
When the train is in an overlapping section where signals of a plurality of different train control methods can be received,
The control information including a signal instructing switching of the train control method and the train control method used by the train according to the route of the train existing in the overlapping section is transmitted to the on-board control device, and In the control information, it has means to give a control instruction of the train control method used by the train,
The on-vehicle controller is
It has a means to perform train control according to the train control system instructed by the ground control device.

  FIG. 1 is a diagram showing an overall schematic configuration of a train control system according to an embodiment to which the present invention is applied. The outline will be described below.

In the figure, the train 103 is shown on the rail.
The section in which the train 103 can travel includes a control range 110 in the radio signal train control system A of the railway signal system (hereinafter referred to as a train control system) that performs train control by radio and a control range 109 in the radio signal train control system B. And a control range 111 in the track circuit signal train control system of the railroad signal system (hereinafter referred to as track circuit signal train control system) that performs train control by the track circuit.
The train 103 existing in each range can receive a signal (including control information) of each train control method. Then, the vehicle travels according to the travel conditions determined by each train control method.
In the same figure, in the section 104 where the train 103 is present, the control range 110 in the radio signal train control method A, the control range 109 in the radio signal train control method B, and the control range 111 in the track circuit signal train control method overlap. doing.
Therefore, the train 103 existing in the overlapping section 104 can receive all signals of the radio signal train control method A, the radio signal train control method B, and the track circuit signal train control method.
Accordingly, the train 103 travels according to any one of the radio signal train control method A, the radio signal train control method B, and the track circuit signal train control method.

In the train control system according to the present embodiment, the ground device determines any one of the train control methods and instructs the train 103.
The train control system (railway signal system) is one of security systems that determine the allowable speed of each train for the purpose of ensuring the safety of train operation. For example, in addition to the above-mentioned ATC and ATS, CBTC (Communications) -Based Train Control), etc.

The train control system according to the present embodiment includes a ground device installed on the ground and an on-vehicle device installed on the train 103 traveling on the track.
The ground device includes a ground control device 105, a ground-side wireless device 100, and a ground-side antenna 101, and the on-board device includes an on-vehicle control device 108, a vehicle-side wireless device 301, and a vehicle-side antenna 107. The configuration of the vehicle upper side radio apparatus 301 will be described later (see FIG. 3).

  The on-board controller 108 transmits the train information 102 from the vehicle upper side antenna 107. The train information 102 includes train position information (see FIG. 6).

  The ground side radio apparatus 100 receives the train information 102 transmitted from the onboard apparatus side by the ground side antenna 101 and transmits the train information 102 to the ground control apparatus 105.

The ground control device 105 has a function of determining a train control method to be used by the train 103.
The train control method (wireless signal train control methods A and B) determined by the ground control device 105 is transmitted from the ground side wireless device 100 to the onboard control device 108 of the train 103 as control information 106 through the ground side antenna 101. .

The control information 106 includes information 206 (switching signal, train control method, train control method signal) that defines the train control method of the train 103 (see FIG. 7). This information will be described later.

  However, even if the on-board control device 108 receives the designation of the train control method from the ground device by the train control method switching signal, the on-board control device 108 transmits the train control method signal designated by the information 206 included in the control information 106. When the upper control device has not received, the information indicating that the train control method signal designated by the ground control device 105 has not been received is transmitted without switching to the designated train control method.

For example, when the on-board controller 108 has not received the signal of the radio signal train control method A when the ground control device 105 is instructed to use the radio signal train control method A as the train control method. The train control method is not switched to the radio signal train control method A. In this case, train control is performed according to the train control method used before being instructed by the ground control device, for example, the track circuit signal method.
Alternatively, after switching to the designated radio signal train control method A, the train 103 may be stopped because the signal of the radio signal train control method A is not received.

  Train information 102 from the train 103 is transmitted from the ground side wireless device 100 to the ground side wireless device control unit 200 included in the ground control device 105.

In the control information 106, for example, as shown in FIG. 7, a destination train ID for identifying a destination train that transmits the train control method, a train control method that specifies the train control method of the train 103, a stop limit position of the train 103, Information 206 such as a switching signal for instructing switching of the train control system and a signal of the train control system is included. When there is no need to switch the train control method, the switching signal is not included. The train control system signal is, for example, a signal that can be received in the track circuit signal train control system control range 111 shown in FIG. 1, and the radio signal train control system A control range 110 or the radio signal train control system B control. This signal can be received in the range 109. Therefore, for example, in the range where the radio signal train control method A control range 110 and the radio signal train control method B control range 109 overlap, each signal of the radio signal train control methods A and B needs to be transmitted and received. However, it is not necessary to send and receive signals of the radio signal train control method B.
