本発明は集中監視システムに関し、特にポーリング方式
にて監視データの収集を行う集中監視システムに関する
。DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a centralized monitoring system, and more particularly to a centralized monitoring system that collects monitoring data using a polling method.
従来技術
従来のポーリング方式を用いたこの種の集中監視システ
ムでは、監視装置から多数の被監視装置に対して、−局
一局指定を行い、指定された被監視装置が応答を返し、
その繰返し処理により全装置の監視データの収集を行っ
ている。Prior Art In this type of centralized monitoring system using the conventional polling method, a monitoring device specifies a large number of monitored devices one by one, and the designated monitored device returns a response.
Through this repeated process, monitoring data for all devices is collected.
この様な従来方式では、−周毎に監視装置からポーリン
グ指定を行ってその応答を待つという方式であるので、
被監視装置が増加したり、返答を返さない被監視装置が
あると、システム全体の監視に時間がかかり、重要なデ
ータ収集が短時間でできなくなるという欠点がある。In this conventional method, the monitoring device specifies polling every cycle and waits for the response.
If the number of monitored devices increases or some monitored devices do not return a response, it will take time to monitor the entire system, making it impossible to collect important data in a short period of time.
発明の目的
本発明の目的は、監視データの迅速なる収集を可能とし
た集中監視システムを提供することである。OBJECTS OF THE INVENTION An object of the present invention is to provide a centralized monitoring system that allows rapid collection of monitoring data.

る集中監視システムが得られる。Structure of the Invention According to the present invention, there is provided a centralized monitoring system including a plurality of monitored devices and a monitoring device that centrally monitors these monitored devices using a polling method, wherein There is obtained a centralized monitoring system characterized in that a reference frame signal is sent to the monitored device, and the monitored device sends out self-monitoring data in a predetermined time slot based on this reference frame signal.
実施例 以下、本発明の実施例を図面を参照して説明する。Example Embodiments of the present invention will be described below with reference to the drawings.
第１図は本発明の実施例の概略を示すシステムブロック
図である。監視局１は複数の被監視局３１〜３ｎからの
監視データを収集して集中監視するものであり、監視装
置が設置されている。FIG. 1 is a system block diagram schematically showing an embodiment of the present invention. The monitoring station 1 collects and centrally monitors monitoring data from a plurality of monitored stations 31 to 3n, and is equipped with a monitoring device.
被監視局３１〜３ｎは被監視装置が夫々設置されており
、監視データを送出可能となっている。Each of the monitored stations 31 to 3n has a monitored device installed therein, and is capable of transmitting monitoring data.
監視局１とこれ等被監視局３１〜３ｎとは通信衛星２に
より接続されている。The monitoring station 1 and these monitored stations 31 to 3n are connected by a communication satellite 2.
監視局１から基準フレーム信号４を送出し、被監視局で
はこの基準フレーム信号４を受信してこの基準フレーム
に基づき、予め割当てられている自タイムスロットに監
視データ（応答信号や状態信号）５を返送するのである
。A reference frame signal 4 is sent from the monitoring station 1, and the monitored station receives this reference frame signal 4 and transmits monitoring data (response signal and status signal) 5 to its own time slot allocated in advance based on this reference frame. will be sent back.
こうすることにより、被監視局では返送すべき監視デー
タを有していなければ、返送する必要かなくなる。By doing this, if the monitored station does not have monitoring data to be sent back, there is no need to send it back.
このタイムスロットの割当て制御方法としては、被監視
局毎に予め固定的に割当られている固定割当て方法や、
接続要求割当て方法等の周知の方法を用いることができ
る。This time slot allocation control method includes a fixed allocation method in which time slots are fixedly allocated in advance to each monitored station,
Well-known methods such as connection request allocation methods can be used.
発明の効果

という効果かある。Effects of the Invention As described above, according to the present invention, when collecting monitoring data, the so-called slotted Aloha method is adopted in which the data of each monitored station is loaded in each time slot and returned. It is possible to collect only the monitoring data of the monitoring station, which has the effect of enabling efficient and high-speed data collection.
