The interlocking device 1 includes an FX (interlocking logic unit) 1-1 and a field controller 1-2, and configures / reverts the course specified by the host device (PRC) 4, switches the switch, and lights the traffic light. FX (interlocking logic unit) 1-1 receives control, setting / cancellation of temporary speed limit of train, setting / cancellation of maintenance work, etc., and field controller 1-2 follows the interlocking logic of FX1-1. The switch of the switch 5 and the light control of the traffic light 6 are performed. The interlocking device 1 is connected to an ATC device (digital ATC) 2 via an I / F (interface) device 3. The ATC device 2 includes an ATC logic unit 2-1, an ATC-LAN 2-2, and a transmitter / receiver 2-3. The ATC logic unit 2-1 receives route information and prompt information from the field controller 1-2 of the interlocking device 1. ATC message generated according to the ATC logic of the ATC logic unit 2-1 is transmitted from the transceiver 2-3 to the track peripheral device 7 via the ATC-LAN 2-2, and from the track peripheral device 7 to the on-board ATC 8 This information is sent to and train control is performed. In addition, in order to perform train control, the ATC device 2 creates train tracking and track circuit information (transmission hold, starting point information) from train detection information obtained from the track circuit 9 and other external information, and stops point information and Train control information such as critical speed information is created and transmitted to the track circuit 9 as an ATC message. Thereby, the train is controlled safely.
[0003]
Here, regarding the conventional route setting signal control, the route setting flow will be described with reference to FIG. When the interlocking device 1 receives a course setting instruction from the PRC 4, a temporary reservation is made to the switch 5 and the track circuit 9 related to the course (1). Then, the related switch 5 is changed to the direction in which the designated route is formed (2). Here, it waits until the switch of the switch 5 is completed (3). In response to the completion of the switch of the switch 5 (4), the provisional reservation of the switch 5 and the track circuit 9 was reserved, and the course setting conditions were established by displaying an auxiliary signal to the ATC device 2 Is notified to the ATC device 2 via the interlocking I / F 3 (5). Based on this, the ATC device 2 creates the starting point information and transmission holding information of the track circuit 9 in the course, recalculates the stop track circuit, and re-trains the train control information such as stop position information and emergency speed information. The ATC message is transmitted to the track circuit 9 (6), and the ATC signal display information corresponding to the course is also transmitted to the interlocking device 1 via the interlocking I / F 3 (6). Based on this ATC signal display information, the interlocking device 1 recognizes that the instructed route has been set (HKR), turns on the traffic light 6 (7), and notifies the PRC 4 of the completion of the route setting.

[Problems to be solved by the invention]
In the conventional system, the interlocking device and the ATC device are separate and independent systems, and both are connected via the I / F device, so that the entire device becomes large and equipment is installed. The necessary occupation area becomes wide. That is, in the equipment room of each station, when a new system is updated, an installation space equivalent to the existing system is required. However, since it is not easy to expand the equipment room newly, it is desirable to use the existing space as efficiently as possible. Therefore, it is necessary to reduce the size of the device in order to install the device in a small space.
Further, the conventional interlocking device and the ATC device are asynchronous and exchange information via the I / F device. For this reason, the operation may be delayed depending on the timing.
[0005]
In view of the above circumstances, an object of the present invention is to integrate the interlocking device and the ATC device into one device, consolidate the functions, and make the entire facility compact.
[0006]
In order to solve the above-mentioned problem, a linked / ATC integrated type apparatus comprising: a linked processing unit, an ATC processing unit, and a linked / ATC integrated logic unit comprising a shared table accessible by the linked processing unit and the ATC processing unit. Prepared,
The interlock processing unit writes the switch result information and the route determination result information created according to the conventionally known interlock logic including the track circuit tracking process to the common table, and at the same time, switches the direction of the switch and lights the traffic light. On the other hand, the ATC processing unit reads the result information from the shared table, creates stop point information and emergency information according to conventionally known ATC logic including track circuit tracking processing , and stops point information and emergency information. Is generated as an ATC message, and a track circuit tracking process common to the processes of both the processing units is used as a common logic.

【The invention's effect】
As described above, according to the present invention, by using a shared memory instead of the conventional I / F device and defining the processing order, the conventional interlocking device and the ATC device are independently performed. It is possible to consolidate the logic that has been integrated into one device, to save space, and to reduce costs.
In addition, since it is possible to exchange data for interlocking logic and ATC logic using a shared memory without using a conventional I / F device, the response time is fast and the processing in the same device is a single thread. Therefore, transmission delay due to timing can be eliminated.
Further, since the interlocking process and the ATC process are integrated, the logic common to both processes can be consolidated as one common logic.
In addition, although the conventional interlocking device and the ATC device operate asynchronously, in the present invention, since the interlocking and the ATC are integrated, the processing time can be greatly shortened.
