Abstract

PURPOSE:To expand command console operating service functions and to reduce the mounting space by providing plural key mats to a command console operating panel and a means for coding key operation information and sending the coded operation information from the command console to a controller. CONSTITUTION:An interface section with a command console 2 and a control section of a command telephone set 3 are mounted in a controller frame 1. Control buttons mounted on the command console are integrated to key mats 3111 of a multi-item input device 311, the key operation information of the mat 3111 is coded and sent from a data control line to a controller 32 via an interface 3112. Thus, the command console operating service function is expanded in this way and the mounting space is saved.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a railway command telephone system.

[Conventional technology]

Conventionally, in this type of command telephone system, the operation buttons mounted on the operation panel of the command console include a call button for an accommodation line and an accommodation telephone set corresponding to the console.

Figure 2 shows the conventional method, with an operation section (
It has a button) 211 and a display section (lamp) 212, and the number of button information reads required corresponds to the number of buttons. Additionally, there is a limit to the number of buttons that can be mounted on the board due to the operable range of the commander.

A button input circuit 221 using a photocoupler is provided in the control device 22 for each control button (operation unit 212) mounted on the command board. Further, each of the lamps (display section 211) mounted on the command table is controlled (lit) by the control device 22 through the output of the first contact 222.

[Problem that the invention seeks to solve]

The above-mentioned conventional system has the disadvantage that a large-scale command system requires a large space to be fully equipped, making it look more like a workbench than a command desk, and there are restrictions on the number of lines and telephones that can be accommodated on the command desk.

[Means for solving problems]

The railway command telephone system of the present invention eliminates the operation buttons conventionally mounted on the operation panel from the operation panel, and replaces the operation buttons with a plurality of key mats, a plurality of connection operation information encoding functions, and a plurality of connection information. By providing a multi-item input device with an encoding and transmitting function on the writing surface, only the display section can be left on the operation panel.

Furthermore, whereas conventionally the display section could only be mounted for the lines accommodated in that stand, it is now possible to display all lines accommodated in other stands and their systems.

In addition, by using a multi-item input device for connection operations, all lines accommodated in Sendai and its system, as well as the display, can be OT-operated.

〔Example〕

FIG. 1 is a conceptual diagram of a system according to an embodiment of the present invention, in which an interface section with a command console 2 and a control section of a command telephone 3 are mounted in a control device 1 (rack).

FIG. 3 shows an embodiment according to the present invention, in which the conventional control buttons mounted on the command console are integrated into a multi-item input device 311, and the connection with the control device 32 is made only by a data control line, regardless of the number of control buttons. AS232C is used as the method.

〔Effect of the invention〕

As explained above, the present invention uses a multi-item input device in the command console operation section to (1) expand the command console operation service function, and (2) remove limitations such as the number of lines that can be accommodated by the command console. 3) It has the effect of updating the image of the conventional command desk.
