【発明の詳細な説明】
本発明は特定の送信局に属する複数の受信局の全部また

において、該受信局に送信局の再送信の聴取の選択を可
能にする方式に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a one-way wireless communication system in which a notification is transmitted by selecting all or each of a plurality of receiving stations belonging to a specific transmitting station. This relates to a method that allows selection of listening options.
一方向無線通信系では受信局に通報を確実に伝えるには
再送信すると効果がある。In one-way wireless communication systems, retransmission is effective in ensuring that notifications are conveyed to the receiving station.

ることにある。本発明の代表的な実施例を図面を用いて
説明する。For example, retransmission in a different time zone is an effective means for a receiving station that did not have a chance to receive and listen to the first transmission due to the time zone of the transmission. However, since the receiving station that is always listening to the reception hears the same report, there is a possibility that the receiving station may lose interest in the report and temporarily stop reception. Conventionally, a receiving station that does not want to hear retransmissions has no choice but to turn off the receiver's power switch, and these operations have the disadvantage that new messages cannot be received or heard during the period when the receiving function is stopped. An object of the present invention is to provide a wireless communication system in which a receiving station blocks retransmission notifications when there is no need to listen to retransmissions, so that only new notifications can be heard. Representative embodiments of the present invention will be described with reference to the drawings.

断されるので何度も聞かされることはない。FIG. 1 is an example of a paging signal sequence sent out from a transmitting station according to the present invention. FIG. 2 shows the transmitting station configuration of the present invention, where 19 is a microphone, 20 is an amplifier, 21 is a sequential transmission switch, and 22
is a common paging signal oscillator, 23 is a simultaneous paging signal oscillator, 2
4 and 25 are individual calling signal oscillators, 26 is a reset signal oscillator, 2T is a setting relay, and 28 is an antenna. The effect is that when transmitting a new report, the conventional receiving station calling signals are sent to each of the common calling signal 1 and general calling signal 2 as shown in Figure 1a, or the common calling signal 1 and individual calling signal 3 as shown in Figure 1b. In this embodiment, one more signal is added and sent. This signal will hereinafter be referred to as reset signal 4. At the time of retransmission, the receiving station calls the common calling signal 1 and the general calling signal 2 or the common calling signal 1 as shown in Fig. 1c and d.
and the individual call signal 3 are sent out, and the reset signal 4 is not sent out. FIG. 3 shows the configuration of a receiving station according to an embodiment of the present invention. In the figure, 5 is an antenna, 6 is a receiver, 7 is a switching circuit, 8 is an amplifier, 9 is a speaker, 10 is a common paging signal detection circuit, 11 is a simultaneous paging signal detection circuit, 12 is an individual paging signal detection circuit, 13 Beam set signal detection circuit 14~
142' is an AND circuit, 15 is an 0R circuit, 16 is a retransmission cutoff signal, and 17 is a marip-flop circuit. In the present invention, in the case of first transmission, the set signal 4 in FIG.
Common paging signal 1 and general paging signal 2 or set signal 4 in FIG. 1b, common paging signal 1 and individual paging signal 3
is received and detected by the detection circuit, and this output is output to the AND circuits 14 to 14''7, and from the output of the circuit 147, it is detected by the detection circuit.
When , the flip-flop circuit 1 is activated regardless of the state of the retransmission cutoff signal 16 (set-reset type).
7 (hereinafter referred to as a flip-flop circuit) is set, and the AN
The outputs of the D circuits 14 and 147 and the output of the circuit 17 are ANDed by an AND circuit 14777. This output causes the switching circuit 7 to operate and the contents of the report to be heard. Next, in the case of retransmission, the logical sum of the common paging signal 1 and the general paging signal 2 in FIG. 1c and the common paging signal 1 and the individual paging signal 3 in FIG. Retransmission can also be heard by operating the switching circuit 7 only when the retransmission is not set to be blocked by the retransmission blocking signal 16. That is, the signal 16 can be used to block retransmission notifications so that they cannot be heard. This signal 16 is provided by opening and closing a switch. The operation will be explained using the receiving station configuration of the embodiment of the present invention shown in FIG. 3. When the transmitting station transmits a new report, the transmitting station sends out a common paging signal 1, a general paging signal 2, and a set signal 4. The contents of the report can be heard regardless of the state of the signal 16. When retransmitting, the common paging signal 1 and the general paging signal 2 or the common paging signal 1 and the individual paging signal 3 are sent out, so when the flip-flop circuit 17 is closed by the signal 16, the contents of the report cannot be heard, but when it is open, the contents of the report cannot be heard. The retransmission notification will be heard. The advantage of the present invention is that when the receiving station understands the contents of the message and no longer needs to hear it, retransmission is cut off by setting the flip-flop circuit 17 to 0FF using the signal 16, so that the message can be heard many times. There isn't.

れる。If you miss the call due to the absence of the recipient, signal 1.
6 is left as is, the retransmission can be heard and the report is reliably conveyed to the receiving station. In addition, the flip-flop circuit 17 is activated by the signal 16 indicating that the retransmission notification is blocked.
Even if the signal is set to 0FF, the reset signal is also sent when a new notification is sent and can be heard, so the application of the present invention brings great benefits in that the notification can be reliably received and retransmission can be blocked. Of course, in addition to this example, almost infinite combinations of signal formats for distinguishing between retransmissions and initial transmissions are conceivable and practical, but all of them are variations or abbreviations of the present invention. Within the scope of the claims.
