Description

本発明は、接点信号を伝送する接点信号伝送システムに関する。 The present invention relates to a contact signal transmission system for transmitting a contact signal.

特定小電力無線を使用して接点信号を伝送する接点信号伝送システムが知られている（例えば、非特許文献１参照）。この接点信号伝送システムは、屋外で約４００ｍ、屋内で約１００ｍの見通し距離で接点信号を伝送することができる。接点信号伝送システムを用いることにより、各種の設備や機械の状態を遠隔監視することができる。 A contact signal transmission system that transmits a contact signal using a specific low-power radio is known (for example, see Non-Patent Document 1). This contact signal transmission system can transmit a contact signal at a line-of-sight distance of about 400 m outdoors and about 100 m indoors. By using the contact signal transmission system, it is possible to remotely monitor the state of various facilities and machines.

また、気象庁は、高度利用者向けの緊急地震速報（予報）を発表する（例えば、非特許文献２参照）。高度利用者向けの緊急地震速報（予報）は、気象庁の多機能型地震計設置のいずれかの観測点において、Ｐ波またはＳ波の振幅が１００ガル以上となった場合、または地震計で観測された地震波を解析した結果、震源・マグニチュード・各地の予測震度が求まり、そのマグニチュードが３．５以上、または最大予測震度が３以上である場合に発表される。高度利用者向けの緊急地震速報（予報）は、気象庁長官の許可を受けた地震予報業務許可事業者によって製造される受信端末で受信することができる。受信端末により、任意の地点での予想した震度や主要動到達時刻を入手することができる。 In addition, the Japan Meteorological Agency announces emergency earthquake warnings (forecasts) for advanced users (see Non-Patent Document 2, for example). Earthquake early warnings (forecasts) for advanced users are observed when the amplitude of the P wave or S wave exceeds 100 gal or at the seismometer at any observation point of the Japan Meteorological Agency's multifunction seismometer. As a result of the analysis of the seismic wave, the seismic center, magnitude, and predicted seismic intensity of each place are obtained, and it is announced when the magnitude is 3.5 or more, or the maximum predicted seismic intensity is 3 or more. Earthquake early warnings (forecasts) for advanced users can be received at a receiving terminal manufactured by an earthquake forecasting business licensed business licensed by the Commissioner of the Meteorological Agency. The receiving terminal can obtain the predicted seismic intensity and main motion arrival time at any point.

例えば、建築会社に設置された受信端末で高度利用者向けの緊急地震速報（予報）を受信し、その受信端末が接続された接点信号送信装置により遠隔地の建築現場の接点信号受信装置に地震速報を送信して建築現場で地震警報を発することができれば、建築現場の安全性を向上させることができる。
しかし、非特許文献１に記載の接点信号伝送システムは、高々数１００ｍの距離しか接点信号を伝送することができない。 For example, an earthquake early warning (prediction) for advanced users is received at a receiving terminal installed at a construction company, and the contact signal transmitting device connected to the receiving terminal causes an earthquake to occur at the contact signal receiving device at a remote construction site. If a breaking news can be transmitted and an earthquake warning can be issued at a construction site, the safety of the construction site can be improved.
However, the contact signal transmission system described in Non-Patent Document 1 can transmit a contact signal only at a distance of several hundred meters at most.

第３世代携帯電話のデータ通信やＬＴＥ（ＬｏｎｇＴｅｒｍＥｖｏｌｕｔｉｏｎ）等を用いて接点信号を伝送することも考えられるが、これらは通信していない状態から通信可能となるまで数十秒要する場合がある。
このため、地震速報のように、伝送すべきデータ量は少ないが、発生した接点信号を短時間で確実に伝送しなければならない用途には適さない。 Although it is conceivable to transmit contact signals using third-generation mobile phone data communication, LTE (Long Term Evolution), etc., it may take several tens of seconds until communication is possible from a non-communication state. .
For this reason, although the amount of data to be transmitted is small, such as earthquake early warning, it is not suitable for applications where the generated contact signal must be transmitted reliably in a short time.

本発明の目的は、発生した接点信号を短時間で確実に遠隔地に伝送することができる接点信号伝送システムを提供することである。 An object of the present invention is to provide a contact signal transmission system capable of reliably transmitting a generated contact signal to a remote place in a short time.

In FIG. 1, the network 300 is shown as a single network. However, the network 300 is configured by a plurality of networks such as a WiMAX network or a network in which a Mobile WiMAX network and the Internet are connected. May be.

接点信号送信装置１００Ａは、地震速報受信端末１１０と、送信サーバ１２０Ａとを有する。
地震速報受信端末１１０は、高度利用者向けの緊急地震速報（予報）を受信する受信端末である。地震速報受信端末１１０は、緊急地震速報（予報）を受信すると、緊急地震速報（予報）を受信したことを送信サーバ１２０Ａに通知する。なお、地震速報受信端末１１０は異常検出部の一例である。

Upon receiving the earthquake early warning (forecast), the earthquake alert receiving terminal 110 notifies the transmission server 120A that the earthquake early warning (forecast) has been received. The earthquake bulletin receiving terminal 110 is an example of an abnormality detection unit.
The transmission server 120A includes a CPU (Central Processing Unit), a memory configured with a RAM (Random Access Memory) and the like, and a storage device configured with a hard disk device and the like. When the CPU executes a predetermined program stored in the memory, the functions of the receiving device determining unit 121A and the contact signal transmitting unit 122A are realized.
The storage device of the transmission server 120A stores a contact signal reception device table 150A shown in FIG. The contact signal receiving device table 150A stores a contact signal receiving device ID (Identifier) and an IP address for each contact signal receiving device 200A to which the contact signal transmitting device 100A transmits a contact signal.
The reception device determination unit 121A determines a contact signal reception device that notifies the occurrence of an earthquake.

また、第１の実施形態では、接点信号送信装置１００Ａは地震速報受信端末１１０と送信サーバ１２０Ａとを有するとしたが、地震速報受信端末１１０と送信サーバ１２０Ａの各機能を１台のコンピュータで実現してもよい。

Further, the contact signal transmitting device 100A may include an abnormality detection device that detects that other abnormality has occurred in addition to or instead of the earthquake early warning receiving terminal 110 and the seismometer.
In the first embodiment, the contact signal transmitting apparatus 100A includes the earthquake early warning receiving terminal 110 and the transmission server 120A.

It can also be set as the structure made.

図３は、本発明の第２の実施形態に係る接点信号送信装置１００Ｂと接点信号受信装置２００Ｂとの構成の一例を示す。
接点信号受信装置２００Ｂは、第１の実施形態と同様に、接点信号送信装置１００Ｂからネットワーク３００を経由して送信される接点信号を受信する。
ネットワーク３００が複数の基地局４００を有し、接点信号送信装置１００Ｂは有線または無線でネットワーク３００に常時接続されており、接点信号受信装置２００Ｂは基地局４００を介して無線でネットワーク３００に常時接続されている点は第１の実施形態と同様である。
第２の実施形態は、接点信号受信装置２００Ｂが現在の位置を示す位置情報を取得して接点信号送信装置１００Ｂに送信し、接点信号送信装置１００Ｂが接点信号受信装置２００Ｂの位置等に応じて接点信号を送信する点が第１の実施形態と異なる。例えば、接点信号送信装置１００Ｂは、地震の震源地から近い場所に設置されている接点信号受信装置２００Ｂにのみ接点信号を送信し、地震の震源地から遠い場所に設置されている接点信号受信装置２００Ｂには接点信号を送信しない。 FIG. 3 shows an example of the configuration of the contact signal transmitter 100B and the contact signal receiver 200B according to the second embodiment of the present invention.
