Abstract

PURPOSE:To provide a non-wasteful simultaneous command system by transmitting dispatching telephone information of command voices, etc., at the side of a control station and an automatic sound recorder is started at the side of an end office with reception of a command start signal. CONSTITUTION:When a simultaneous command is produced, a control station transmits a command start signal (a) and then a command start message (b) to each end office via each branch station to show the start of a simultaneous command. At each end office, the ball of the telephone started by the signal (a) rings. When the speech receiver of this telephone is picked up, each end office sends an answer signal back to the control station via each branch station. The center station monitors the answer signal received from each end office and transmits a command start signal (c) and then a command voice (d) after confirming that a prescribed number or more of end offices sent the answers. Then each end office receives the signal (c) and actuates an automatic sound recorder in a state (e) to record the voices (d) transmitted continuously from the control station.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simultaneous command system in a wireless public relations system such as a disaster prevention administrative wireless system installed in each prefecture.

[0002]

2. Description of the Related Art FIG. 1 shows an overall configuration diagram of a prefecture disaster prevention administrative radio system. In FIG. 1, reference numeral 1 is a control station that sends a notification such as a simultaneous command to each terminal station via a branch station provided in each predetermined area, and 2 is a control station and is connected to the terminal station by a multiple wireless line or the like and controls. A branch station that relays and transmits a series of simultaneous command signals from a station to a terminal station in a predetermined area, and 3 has a plurality of terminal stations arranged for each administrative division that have means for receiving and recording the series of simultaneous command signals. Shows.

FIG. 3 is a time chart showing an example of a conventional simultaneous command system in the above-mentioned prefecture disaster prevention administrative radio system.
a is a start signal for the simultaneous command, b is a command start message, and d
Indicates the command voice, and e indicates the recording state of the recorder of the terminal station.

Next, this operation will be described. When the control station 1 activates the simultaneous command, a command activation signal a is transmitted to each terminal station 3 through the branch station 2. Upon receiving this command activation signal a, each terminal station 3 activates the telephone, speaker, etc. attached to it, activates the automatic recorder, sets the recorder in the recording state e, and then sends a response signal to the branch station 2 It returns to the control station 1 via.

While confirming the response from each terminal station 3, the control station 1 repeatedly sends a command start message b such as "Please wait as it is because a simultaneous command will be issued from now on." After confirming that 3 has responded, the command voice d is transmitted.

[0006]

SUMMARY OF THE INVENTION In the above prior art,
Since the automatic recorders are activated when the command activation signal a of the simultaneous command is received at each terminal station, all terminal stations include message sounds (repetition of the command start message b) that is completely unrelated to the command content. I had the problem of recording.

In view of the above situation, it is an object of the present invention to provide a streamlined broadcast command system in which only broadcast command information such as command voices directly related to command contents can be recorded at each terminal station side.

[0008]

According to the present invention, in order to achieve the above object, a control station transmits a command start signal following a command start message, and then transmits command command information such as a command voice to the terminal station side. Then, when the above-mentioned command start signal is received, the automatic recorder installed together is started.

[0009]

As a result, since only the command voice is recorded at each terminal station without recording the command start message sound that is not related to the content of the simultaneous command, a wasteful simultaneous command system can be realized.

[0010]

EXAMPLE An example of the simultaneous command system according to the present invention is shown in FIG.
Shown in. The same signals as those in the conventional example shown in FIG. 3 are designated by the same reference numerals. Reference numeral c is a command start signal transmitted from the control station before transmitting the command voice.

When issuing a simultaneous command, the control station 1 sends a command start signal a to the terminal stations 3 via the branch station 2 to the terminal stations 3 following the command activation signal a, as in the conventional case, to the effect that a simultaneous command will be issued. To do.

In each terminal station 3, the bell of the telephone set activated by the command activation signal a rings. When the handset of this telephone is lifted, each terminal station returns a response signal to the control station 1 via the branch station 2. The control station 1 monitors response signals from each terminal station, confirms that a predetermined number or more of terminal stations have responded, sends a command start signal c, and then sends a command voice d.

At each terminal station 3, the control station 1 receives the command start signal c and sets the attached automatic recorder to the recording state e.
The command voice d continuously transmitted from is recorded.

In the above embodiment, as shown in FIG.
The disaster prevention administrative radio system including a plurality of branch stations 2 and a plurality of terminal stations 3 has been described as an example, but it has a master station for transmitting a series of simultaneous command signals and a means for recording the simultaneous command signals from the master station. It is also applicable to the simultaneous command system in a general communication system including a plurality of slave stations.

[0015]

As described above, according to the present invention, since only the command voice is recorded on each slave station side without recording the message sound unrelated to the content of the simultaneous command, it is possible to realize a wasteful simultaneous command system. Becomes

Claims (2)

[Claims] 1. A master station and a plurality of slave stations are arranged, and the master station transmits a series of simultaneous command signals including a command start signal, a command start message following the signal, and a command voice signal, Each slave station has a recording means for recording the simultaneous command signal from the master station, and after receiving the command start signal from the master station, starts the recording means and records the subsequent received signal. In the method, the master station transmits a signal for activating the recording means of each slave station after transmitting the command activation signal, the simultaneous command method. 2. A master station and a plurality of slave stations are arranged, and the master station transmits a series of simultaneous command signals including a command start signal, a command start message following the signal, and a command voice signal, Each slave station has a recording means for recording the simultaneous command signal from the master station, and after receiving the command start signal from the master station, starts the recording means and records the subsequent received signal.
