Description of the Related Art In a conventional simultaneous command, a control station sends an acceptance confirmation request signal to all terminal stations via a master station after transmitting the content of the simultaneous command notification. Upon receiving the acceptance confirmation request signal, each terminal station transmits the acceptance response signal to the control station via the master station at a predetermined timing. The control station confirms the acceptance status of the terminal station by receiving the acceptance response signal.

いる。The reception response signal is transmitted sequentially for each terminal station, and after receiving the reception response signal from all the terminal stations targeted for the simultaneous command (after receiving the response information of all the terminal stations targeted for the simultaneous command). Alternatively, after a lapse of a certain period of time, the terminal station is set in a standby state (a state in which the simultaneous command ends and it is possible to transmit or receive by itself. Hereinafter, referred to as a standby state).

待受状態となることができない。In this conventional simultaneous command reception confirmation system, if there are many terminal stations subject to the simultaneous command, a longer reception confirmation time (time for confirmation of reception after notification of simultaneous command) is required.
In addition, even if the terminal station has already transmitted the command response signal, all terminal stations must have transmitted the command response signal.
Cannot be in standby.

ある。更に、受令応答信号を既に送信し終えた端末局で
も、一斉指令対象の端末局全てが受令応答信号を送信し
終えるまで待たなければ待受状態となることができない
という欠点がある。The above-mentioned prior art has a drawback in that in receiving confirmation after receiving the simultaneous command, if many terminal stations are subject to the simultaneous command, it takes a lot of time for receiving confirmation. Further, there is a disadvantage that even a terminal station that has already transmitted the command response signal cannot enter the standby state unless it waits until all the command-targeted terminal stations have transmitted the command response signal.
【０００６】そこで本発明では、一斉指令受令確認によ
る端末局の捕捉時間（受令応答信号を送信し終えてから
待受状態となるまでの時間）を短くすることを目的とす
る。In view of the above, an object of the present invention is to shorten the acquisition time (time from the end of transmission of the command response signal to the standby state) of the terminal station by confirmation of simultaneous command reception.

とができるため、回線の有効利用にも繋がる。In order to achieve the above object, the present invention is such that the master station also monitors an acceptance response signal transmitted by a terminal station under the master station. Furthermore, by receiving the acceptance response signal transmitted by the terminal station at the master station and confirming the acceptance, sequentially from the terminal station that was able to confirm the acceptance,
It is designed to be in a standby state. Then, after receiving the acceptance response signals of all the terminal stations under the parent station, the parent station collectively transmits the acceptance response information of all the terminal stations under its own station to the control station. Therefore, the acquisition time of the terminal station by the simultaneous command can be shortened, and the terminal station in the standby state does not need to wait until all the terminal stations targeted for the simultaneous command have finished transmitting the command response signal to the control station. Since communication is possible, it leads to effective use of the line.

After that, put it in the standby state. (The terminal station 14 that has confirmed receipt of the command response signal 22 is brought into the standby state in order.) The terminal station 14 that has transmitted the command response signal 22.
In order to put the terminal into a standby state, a simultaneous command recovery signal (a signal to put the terminal station 14 into a standby state) 23 is transmitted via the transmitter / receiver 11, the antenna 12, the single line 13, and the antenna 15 of the terminal station 14. It is transmitted to the line connection control device 17 of the terminal station 14. Furthermore, in order to notify the control station 1 which terminal station 14 is in the stand-by state, a terminal restoration signal (a signal notifying the terminal station in the stand-by state) 24 is sent to the transmitter / receiver 9 and the antenna. 8, the multiplex line 6, the antenna 5, and the transmission / reception device 4 to transmit to the simultaneous command control device 3.

とができる。Next, the acquisition time of the terminal station will be compared between the simultaneous command reception confirmation method of this embodiment and the conventional simultaneous command reception confirmation method. Even in the simultaneous command reception confirmation method of the present embodiment and the conventional simultaneous command reception confirmation method, the reception response signal 22 is transmitted in the order of the terminal station 14-1, the terminal station 14-2, ..., The terminal station 14-10. is doing. The interval of transmitting the acceptance response signal 22 is 1 second. In the case of the terminal station 14-1 which has transmitted the reception response signal earliest, the control station sends the restoration signal to the terminal station 14-1 in the conventional simultaneous command reception confirmation method until 10 seconds have elapsed after the reception response signal was transmitted. Do not send to the station.
On the other hand, in the simultaneous reception confirmation method of the present embodiment, the master station can transmit the recovery signal within 1 second after transmitting the reception response signal (however, the master station 7 recovers to the terminal station 14-1). The signal transmission timing is earlier than the timing at which the terminal station 14-2 transmits the acceptance response signal to the master station 7). Therefore, in the simultaneous reception confirmation method of the present embodiment, as compared with the conventional simultaneous reception confirmation method, the number of terminal stations for which the acquisition time becomes short becomes overwhelmingly large, so that the acquisition time by the simultaneous instruction can be shortened.

However, the present invention is not limited to this. Similarly, in a communication system where there are multiple master stations and terminal stations,
The master station can shorten the reception confirmation time by sequentially putting the terminal stations, which have confirmed reception of the reception response signal, into the standby state.
