Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optimal automatic control system for feeding equipment for train operation in a remote monitoring control system (electric power control system) using a computer.

[0002]

2. Description of the Related Art In a remote monitoring and control system using a computer, when it is not necessary to supply electric power to a train until the last train passes and the first power generation vehicle operates, the power supply is reduced to reduce the cost of electricity. The switch is opened. The method is implemented as follows by the system of FIG.

In FIG. 5, the train number and position information (position on the track circuit of the train) of the operation management system 1 are taken into the power distance control system 2.

(1) The power supply stop time is extracted in advance from the train schedule, and the time for opening and closing the power supply switch to the train passage section is determined from that time and automatically controlled.

(2) When the train transit time is changed due to a train accident or the like, the electric power dispatcher (person) who is contacted by the train operation manager changes the automatic control time or cancels the automatic control. , "Open" and "close" the switch by individual control (manually performed by the commander).

[0006]

The conventional control system as described above has the following problems. First, as described in (2) above, the train operation manager contacts the electric power dispatcher, so that a human error, that is, forgetting to contact or a contact error occurs. Moreover, since the electric power commander changes the automatic control time, it is manual rather than automatic, and a human error, that is, a time change error occurs, or the optimum time cannot be input on time. There is also a problem that the time change cannot be physically made in time. Furthermore, since the power dispatcher manually controls the opening and closing of the switch by individual control, there is a problem that it is manual rather than automatic, and human error, that is, erroneous control occurs.

The present invention has been made in view of the above points, and an object thereof is to provide a scheduled transmission method in a distant monitoring control system capable of eliminating human error by automatic control and ensuring safe and accurate control. It is in.

[0008]

[Means for Solving the Problems] Regarding the problems of forgetting to contact or making an error in contact, artificial contact is omitted. The time change error occurs, or the optimum time cannot be input on time,
As for the problem that the time change cannot be physically made in time, the following method is proposed to automatically optimize the time change. The problem that the electric power dispatcher manually controls the opening and closing of the switch by individual control causes erroneous control, which makes the control automatic.

According to the present invention, in a scheduled transmission / reception system in a remote monitoring and control system for automatically controlling feeding equipment by an electric power distance control system and an operation management system, the electric power distance control system is provided with data of a last train number and a starting train number. The train number table that stores the train position data and the train position data table that stores the train position data and feeder section numbers that belong to it, the train section number and the switch numbers that belong to it, and the open / close status of the switch A train section direction table stored in order of direction is provided, and the train number and train position data are synchronously fetched from the operation management system, and whether or not the fetched train number matches the last train number in the train number table. If there is a match, the data that matches the train position data acquired at that Searching from the train position data table, the feeding circuit section number calculated, searching numbers that match the feeding circuit section number obtained said from said feeding circuit section direction table,
It is characterized in that the switches of all feeder sections in the reverse train traveling direction are controlled to be opened from the feeder section numbers adjacent to the retrieved train section number in the backward train traveling direction.

[0010]

[Operation] From the train position information, the section through which the train has passed is obtained, and that section can be automatically stopped.
Since automatic control is performed in this manner, human error does not occur. Therefore, safe and accurate control can be secured.

The electric power distance control system 12 includes a train number table in which data of last train numbers and starting train numbers is stored, a train position data table in which train position data and feeder section numbers belonging to the train position data are stored, and feeder section numbers. Further, there is provided a feeder section direction table in which the switch numbers belonging to the switch and the open / closed states (on / off) of the switch are stored in order of the traveling direction of the train.

The power distance control system 12 synchronously fetches the train number and the train position from the operation management system 1. First, the final train number in the train number table is compared with the train number received from the operation management system 1 (step S ₁ ). If the received train number matches the last train number in the train number table, the train position data table is searched for data that matches the train position data that was simultaneously acquired at that time to obtain the feeder section number (step S ₂ ). A number corresponding to the obtained feeder section number is searched from the feeder section direction table, and all feeders in the train traveling reverse direction are searched from the feeder section numbers adjacent to the retrieved feeder section number in the train traveling reverse direction. the opening control switch of conductive sections (step S _3).

As described above, by stopping the feeding of the passing section in synchronism with the movement of the train position, it is possible to automatically control at the optimum time without any manual operation.
