Description

Description: TECHNICAL FIELD The present invention relates to an emergency command line control method.

(Prior art)

Conventionally, in this type of emergency command line control method, a command board operator manually checks the response status of each terminal to confirm the responses of all terminal devices, and then issues a simultaneous command. Also, at the time of restoration, the restoration of each terminal device was similarly checked to confirm that all restorations had been completed, and then the line was restored manually.

[Problems to be solved by the invention]

In the conventional emergency command line control method described above, the command commander checks the status of each terminal device and then issues and restores the simultaneous command. The command may not be transmitted to the terminal device. In addition, since the line is controlled by a manual operation of a command table operator, there is a disadvantage that prompt command work may not be performed immediately.

[Means for solving the problem]

In an emergency command line control method for issuing an emergency command to a plurality of non-command terminals from the command console, calling the non-command terminal via the trunk by pressing down the command button from the command console,
Note that at this time, all responses from the non-command terminal are monitored by the response / recovery monitoring unit by forcibly interrupting the non-command terminal that is busy, and when all the responses from all the non-command terminals are detected. The response / recovery monitoring unit notifies the command table that the command call is possible, and based on this notification signal, the command control unit in the command table performs line connection between the commander and all non-command terminals. Control the trunk control unit and inform the commander that the command call is possible.After the command call is completed, the response / recovery monitoring unit monitors the recovery status of all non-command terminals, and when this complete recovery is detected, the command An emergency command line control method, comprising: notifying the command table and controlling the trunk control unit so that the command console sets the line connection state for normal use.

〔Example〕

Next, the present invention will be described with reference to the drawings. FIG. 1 is a system block diagram showing one embodiment of the present invention.

In FIG. 1, an emergency command device according to the present embodiment includes trunks (hereinafter referred to as TRKs) 2a to 2n connected to terminal devices (hereinafter referred to as TRMs) 1a to 1n and a call path switch (hereinafter referred to as SW) for accommodating TRKs 2a to 2n. 3 and a detector (hereinafter referred to as DE) that monitors the response / recovery status of TRKs 2a to 2n and detects all responses / recoveries
T) 4, a command base (hereinafter referred to as BD) 5, and a trunk control unit (hereinafter referred to as CT) which controls connection of all TRKs 2a to 2n according to instructions from BD5.
L) 6 and an amplifier (hereinafter referred to as AMP) 7 for amplifying the command voice from BD5 and sending it to TRKs 2a to 2n.

 Next, the operation of this embodiment will be described.

Usually any of TRK1a-1n is TRK2a-2n and SW3
, And DET4 monitors the status of TRK2a ~ 2n. When the operator wants to perform a simultaneous command from BD5 to all the TRMs 1a to 1n, when the operator presses a command button (not shown), the CTL 6 reads out the TRMs 1a to 1n via the TRKs 2a to 2n. At this time, an interrupt is issued to the busy TRM. DET
4 monitors the TRKs 2a to 2n and detects response states of all the TRMs 1a to 1n and sends an all terminal response display signal to the BD 5. When the BD5 receives this all-terminal response display signal, it automatically sends an instruction from the internal command control unit (not shown) to the CTL6, and the CTL6
The TRKs 2a to 2n switch connection to the AMP7 side as shown by the broken line, and the operator issues a command voice from the microphone (not shown) of the BD5. Therefore, this command voice is amplified on the AMP7 side and output from the speakers (not shown) of all the TRMs 1a to 1n via the TRKs 2a to 2n. After listening to this directive, each TRM1a ~ 1
n restore. When DET4 monitors TRK2a ~ 2n and detects the full recovery status, it sends a full recovery status indication signal to BD5, and BD5
Instruct the CTL 6 to restore the connection of the TRKs 2a to 2n indicated by broken lines.

〔The invention's effect〕

As described above, according to the present invention, by detecting all responses / restorations of a plurality of terminal devices and sending a display signal to the command base, an effect of providing a speedy command operation without a confirmation error can be obtained.

[Brief description of the drawings]

FIG. 1 is a system block diagram showing one embodiment of the present invention. 1a-1n: Terminal equipment (TRM), 2a-2n: Trunk (TR

Claims (1)

(57) [Claims] In an emergency command line control method for issuing an emergency command from a command console to a plurality of non-command terminals, a non-command terminal is called via a trunk by depressing a command button from the command console. The response / recovery monitoring unit monitors all responses from non-command terminals by forcibly interrupting the non-command terminals, and monitors response / recovery when all responses from all non-command terminals are detected. Unit notifies the command console that the command call is possible, and based on this notification signal, the command control unit in the command console controls the trunk control unit to perform line connection between the commander and all non-command terminals. Control and inform the commander that the command call is possible, and after the command call is completed, the response / recovery monitoring unit monitors the recovery status of all non-command terminals, and when this complete recovery is detected, notifies the command table, Is the normal line Emergency command line control method characterized by controlling the trunk controller in the trunk controller so as to continue state.
