Description

【０００１】
【発明の属する技術分野】
本発明は、通信システムにおける一斉指令受令確認方式に関するものである。
【０００２】
【従来の技術】
従来の一斉指令は、一斉指令通報内容送信後、統制局より親局経由で全端末局へ受令確認要求信号を送信する。受令確認要求信号を受信すると各端末局は予め決められたタイミングで受令応答信号を親局経由で統制局へ送信する。受令応答信号を受信することにより統制局は端末局の受令状況を確認する。
【０００３】
受令応答信号は端末局毎に順次送信されるもので、一斉指令対象の全端末局から受令応答信号を受信した後（一斉指令対象の全端末局の応答情報受信後）、または一定時間経過後、端末局が待受状態（一斉指令が終了して自ら送信することも受信することもできる状態。以下、待受状態と称する。）となるようにしている。
【０００４】
この従来の一斉指令受令確認方式では、一斉指令対象の端末局が多いと、より多くの受令確認時間（一斉指令通報後の受令確認のための時間）を要する。また、既に受令応答信号を送信し終えた端末局でも、端末局全てが受令応答信号を送信し終えてからでないと、待受状態となることができない。
【０００５】
【発明が解決しようとする課題】
前述の従来技術では一斉指令通報後の受令確認において、一斉指令対象の端末局が多いと、多くの受令確認時間を要するという欠点がある。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。
【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。
【０００７】
【課題を解決するための手段】
本発明は、上記目的を達成するため、親局傘下の端末局が送信する受令応答信号を親局でも監視するようにしたものである。更に、端末局が送信する前記受令応答信号を親局で受信して受令確認を行うことにより、受令確認できた端末局から順次、待受状態にさせるようにしたものである。そして、親局傘下の全端末局の受令応答信号を受信した後、親局は自局傘下の全端末局の受令応答情報を一括して統制局へ送信するようにしたものである。
従って、一斉指令による端末局の捕捉時間を短くすることができると共に、一斉指令対象の端末局全てが受令応答信号を統制局へ送信し終えてからでなくても待受状態の端末局は通信を行うことができるため、回線の有効利用にも繋がる。
【０００８】
【発明の実施の形態】
以下、本発明の一実施例である一斉指令受令確認方式について図１〜３を参照して説明する。図１は通信システムの構成を示すブロック図であり、図２は本実施例の一斉指令受令確認方式を示すシーケンス図である。図３は従来の一例である一斉指令受令確認方式を示すシーケンス図である。
【０００９】
まず、通信システムの各構成要素、本実施例の一斉指令受令確認方式に用いる信号について説明する。１は統制局であり、２〜５は統制局１の構成要素である。２は統制台、３は一斉指令制御装置、４は送受信装置、５は空中線である。６は多重回線である。７は親局であり、８〜１２は親局７の構成要素である。８は空中線、９は送受信装置、１０は回線制御装置、１１は送受信装置、１２は空中線である。１３は単一回線である。１４（１４−１〜１４−１０）は端末局であり、１５〜１８は端末局１４の構成要素である。１５は空中線、１６は送受信装置、１７は回線接続制御装置、１８は一斉受令端末である。１９〜２６は、本実施例、従来例での一斉指令受令確認方式において、統制局１、親局７、端末局１４との間で伝送される信号である。
【００１０】
次に、本実施例の一斉指令受令確認方式について説明する。扱者が統制台２を操作することにより、統制局１は一斉指令を起動し親局７を経由して端末局１４へ一斉指令通報内容を送信する。そして、扱者により受令確認指示がされた場合、受令確認要求信号１９が一斉指令制御装置３から送受信装置４、空中線５、多重回線６を経由して親局７へ送信される。更に、受令確認要求信号１９は、親局７の空中線８、送受信装置９、回線制御装置１０、送受信装置１１、空中線１２、単一回線１３、端末局１４の空中線１５、送受信装置１６を経由して回線接続制御装置１７へ送信される。
【００１１】
回線接続制御装置１７では受令確認要求信号１９を受信するか否かを監視している。そして、受令確認要求信号１９を受信すると一斉指令受令端末１８に受令確認要求指示信号２０を送信する。その結果、一斉指令受令端末１８はブザーやランプにより受令確認要求を端末局１４の扱者に通知する。
【００１２】
端末局１４の扱者の操作により一斉受令端末１８から受令応答情報信号２１が送信されると、自局内受令端末の受令応答信号２２が送受信装置１６、空中線１５、単一回線１３、空中線１２、送受信装置１１を経由して親局７の回線制御装置１０へ送信される。
【００１３】
親局７の回線制御装置１０は、親局７傘下の端末局１４から送信される受令応答信号２２を監視することにより、端末局１４が送信してきた受令応答信号２２を受信した後、待受状態とさせる。（受令応答信号２２を受信確認できた端末局１４から順次、待受状態にさせる。）受令応答信号２２を送信してきた端末局１４を待受状態にさせるために、一斉指令復旧信号（端末局１４を待受状態にする信号）２３を送受信装置１１、空中線１２、単一回線１３、端末局１４の空中線１５を経由して、端末局１４の回線接続制御装置１７へ送信する。更に、待受状態にした端末局１４はどの端末局であるかを統制局１へ通知するために、端末復旧信号（待受状態にした端末局を通知する信号）２４を送受信装置９、空中線８、多重回線６、空中線５、送受信装置４を経由して一斉指令制御装置３へ送信する。
【００１４】
端末局１４の回線接続制御装置１７は一斉指令復旧信号２３を監視している。一斉指令復旧信号２３を受信すると、一斉受令端末１８に復旧信号（一斉受令端末１８を待受状態にする信号）２５を送信して待受状態にさせる。
【００１５】
次に端末局の捕捉時間について、本実施例の一斉指令受令確認方式と従来の一斉指令受令確認方式とで比較する。本実施例の一斉指令受令確認方式及び従来の一斉指令受令確認方式でも、端末局１４−１、端末局１４−２、…、端末局１４−１０の順番で受令応答信号２２を送信している。そして、受令応答信号２２を送信する間隔は１秒である。最も早く受令応答信号を送信した端末局１４−１の場合、従来の一斉指令受令確認方式では受令応答信号を送信してから１０秒経過してからでないと統制局は復旧信号を端末局へ送信してこない。一方、本実施例の一斉受令確認方式では受令応答信号を送信してから１秒以内で親局が復旧信号を送信することができる（但し、親局７が端末局１４−１に復旧信号を送信するタイミングが、端末局１４−２が親局７へ受令応答信号を送信するタイミングよりも早い場合）。従って、従来の一斉指令受令確認方式に比べて本実施例の一斉受令確認方式は捕捉時間が短くなる端末局が圧倒的に多くなるため、一斉指令による捕捉時間を短縮させることができる。
【００１６】
本実施例では統制局、親局がそれぞれ１局ずつ、端末局が１０局存在する通信システムについて説明したが、これに限定されるものではない。親局、端末局が共に複数局存在する通信システムでも同様にして、親局は、受令応答信号を受信確認できた端末局から順次、待受状態とさせることにより、受令確認時間を短縮させることができる。
【００１７】
【発明の効果】
本発明によれば、既に受令応答信号を送信し終えた端末局は受令応答信号を送信していない端末局全てが受令応答信号を送信し終えるまで待つことなく、一斉指令を終了させることができる。また受令確認時間を短縮することにより、一斉指令による端末局の捕捉時間を短くすることができる。その結果、回線使用の効率化を図ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a simultaneous command acceptance confirmation method in a communication system.
[0002]
[Prior art]
In the conventional general command, after transmitting the content of the general command report, the control station transmits an acceptance confirmation request signal to all terminal stations via the master station. When receiving the acceptance confirmation request signal, each terminal station transmits an acceptance response signal to the control station via the master station at a predetermined timing. By receiving the command response signal, the control station confirms the command status of the terminal station.
[0003]
The command response signal is transmitted sequentially for each terminal station. After receiving the command response signal from all terminal stations subject to simultaneous command (after receiving response information of all terminal stations targeted by simultaneous command) or for a certain period of time After the elapse of time, the terminal station is set in a standby state (a state in which the simultaneous command is completed and can be transmitted and received by itself, hereinafter referred to as a standby state).
[0004]
In this conventional simultaneous command reception confirmation method, if there are a large number of terminal stations subject to the simultaneous command, more time is required for confirmation of the command (time for confirming the command after reporting the general command). In addition, even a terminal station that has already transmitted an acceptance response signal cannot enter a standby state until all the terminal stations have completed transmission of the acceptance response signal.
[0005]
[Problems to be solved by the invention]
In the prior art described above, there is a drawback in that it takes a lot of time for confirmation of orders when there are many terminal stations subject to simultaneous orders in order confirmation after notification of simultaneous orders. Furthermore, even a terminal station that has already transmitted an acceptance response signal has a drawback that it cannot enter a standby state until all terminal stations subject to simultaneous command have finished transmitting the acceptance response signal.
[0006]
Therefore, an object of the present invention is to shorten the terminal station capture time (time from completion of transmission of the command response signal to the standby state) based on simultaneous command command confirmation.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, an acceptance response signal transmitted from a terminal station under the parent station is also monitored by the parent station. Further, the command response signal transmitted from the terminal station is received by the master station and the command is confirmed, so that the terminal stations that have confirmed the command are sequentially put into a standby state. Then, after receiving the reception response signals of all the terminal stations belonging to the parent station, the parent station transmits the reception response information of all the terminal stations belonging to the own station to the control station in a lump.
Accordingly, it is possible to shorten the terminal station capture time by the simultaneous command, and the terminal station in the standby state even after all the terminal stations subject to the simultaneous command have not transmitted the reception response signal to the control station. Since communication can be performed, it leads to effective use of the line.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a simultaneous command acceptance confirmation method according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram showing a configuration of a communication system, and FIG. 2 is a sequence diagram showing a simultaneous command acceptance confirmation method of this embodiment. FIG. 3 is a sequence diagram showing a simultaneous command acceptance confirmation method as an example of the prior art.
[0009]
First, each component of the communication system and signals used in the simultaneous command acceptance confirmation method of this embodiment will be described. 1 is a control station, and 2 to 5 are components of the control station 1. 2 is a control table, 3 is a simultaneous command control device, 4 is a transmission / reception device, and 5 is an antenna. Reference numeral 6 denotes a multiple line. 7 is a master station, and 8 to 12 are components of the master station 7. 8 is an antenna, 9 is a transmission / reception device, 10 is a line control device, 11 is a transmission / reception device, and 12 is an antenna. Reference numeral 13 denotes a single line. 14 (14-1 to 14-10) is a terminal station, and 15 to 18 are components of the terminal station 14. 15 is an antenna, 16 is a transmission / reception device, 17 is a line connection control device, and 18 is a simultaneous command terminal. Reference numerals 19 to 26 denote signals transmitted between the control station 1, the master station 7, and the terminal station 14 in the simultaneous command reception confirmation method according to the present embodiment and the conventional example.
[0010]
Next, the simultaneous command acceptance confirmation method of the present embodiment will be described. When the operator operates the control stand 2, the control station 1 activates the simultaneous command and transmits the content of the simultaneous command notification to the terminal station 14 via the master station 7. When an instruction confirmation instruction is given by the operator, an instruction confirmation request signal 19 is transmitted from the simultaneous instruction control device 3 to the master station 7 via the transmission / reception device 4, the antenna 5, and the multiple line 6. Further, the acceptance confirmation request signal 19 passes through the antenna 8 of the master station 7, the transmission / reception device 9, the line control device 10, the transmission / reception device 11, the antenna 12, the single line 13, the antenna 15 of the terminal station 14, and the transmission / reception device 16. And transmitted to the line connection control device 17.
[0011]
The line connection control device 17 monitors whether or not an acceptance confirmation request signal 19 is received. Then, upon receipt of the acceptance confirmation request signal 19, an acceptance confirmation request instruction signal 20 is transmitted to the simultaneous instruction acceptance terminal 18. As a result, the simultaneous command receiving terminal 18 notifies the operator of the terminal station 14 of an order confirmation request by a buzzer or a lamp.
[0012]
When the command response information signal 21 is transmitted from the simultaneous command terminal 18 by the operation of the operator of the terminal station 14, the command response signal 22 of the command terminal within the local station is transmitted to the transceiver 16, the antenna 15, the single line 13. The signal is transmitted to the line control device 10 of the master station 7 via the antenna 12 and the transmission / reception device 11.
[0013]
The line control device 10 of the master station 7 monitors the command response signal 22 transmitted from the terminal station 14 being served by the master station 7, and receives the command response signal 22 transmitted from the terminal station 14, Set to standby mode. (Sequentially enter the standby state from the terminal station 14 that has confirmed reception of the acceptance response signal 22.) In order to place the terminal station 14 that has transmitted the acceptance response signal 22 into the standby state, a simultaneous command restoration signal ( A signal 23 for setting the terminal station 14 in a standby state) is transmitted to the line connection control device 17 of the terminal station 14 via the transmitting / receiving device 11, the antenna 12, the single line 13, and the antenna 15 of the terminal station 14. Further, in order to notify the control station 1 which terminal station 14 is in the standby state, the terminal restoration signal (signal for notifying the terminal station in the standby state) 24 is sent to the transmission / reception device 9 and the antenna. 8, via the multiple line 6, the aerial line 5, and the transmission / reception device 4, to the simultaneous command control device 3.
[0014]
The line connection control device 17 of the terminal station 14 monitors the simultaneous command restoration signal 23. When the simultaneous command recovery signal 23 is received, a recovery signal (a signal for setting the simultaneous command terminal 18 in a standby state) 25 is transmitted to the simultaneous command terminal 18 to enter a standby state.
[0015]
Next, the acquisition time of the terminal station is compared between the simultaneous command reception confirmation method of this embodiment and the conventional simultaneous command reception confirmation method. The command response signal 22 is transmitted in the order of the terminal station 14-1, the terminal station 14-2,..., The terminal station 14-10 in the simultaneous command reception confirmation method and the conventional simultaneous command reception confirmation method of the present embodiment. is doing. And the interval which transmits the acceptance response signal 22 is 1 second. In the case of the terminal station 14-1 that transmitted the command response signal earliest, the control station sends a recovery signal only after 10 seconds have elapsed since the command command response signal was transmitted in the conventional simultaneous command command confirmation method. Does not send to the station. On the other hand, in the simultaneous acceptance confirmation method of the present embodiment, the master station can send the restoration signal within one second after sending the acceptance response signal (however, the master station 7 is restored to the terminal station 14-1). When 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, compared to the conventional simultaneous command reception confirmation method, the simultaneous reception command confirmation method of this embodiment has an overwhelming increase in the number of terminal stations whose acquisition time is shortened, so that the acquisition time by the simultaneous command can be shortened.
[0016]
In the present embodiment, a communication system has been described in which there are one control station and one master station, and ten terminal stations, but the present invention is not limited to this. Similarly, even in a communication system in which there are multiple master stations and terminal stations, the master station shortens the acceptance confirmation time by placing the master station in a standby state sequentially from the terminal station that has confirmed receipt of the acceptance response signal. Can be made.
[0017]
【Effect of the invention】
According to the present invention, a terminal station that has already transmitted an acknowledgment response signal ends the simultaneous command without waiting for all terminal stations that have not transmitted the acknowledgment response signal to finish transmitting the acknowledgment response signal. be able to. Further, by shortening the reception confirmation time, it is possible to shorten the terminal station acquisition time by the simultaneous instruction. As a result, the efficiency of line usage can be improved.
