Abstract

PURPOSE:To collect a detailed data of a specific station in parallel while monitoring a state change of all stations in a short time by providing a detailed data collection function through the use of a detailed data transmission slot provided in a control frame in addition to the polling of a usual state change data. CONSTITUTION:A control frame on a satellite line is provided with a polling slot sending a polling command from a monitor station, a state change response slot 9 for sending a state change data for each station and a slot 10 for sending a detailed data through which a specific station sends its own detailed monitor data to a monitor station. Then monitored stations (A)2-(N)4 send a state change data to a determined position in the state change reply slot 9, and the monitored station designated by a polling signal 6 sends the detailed data of its own station to the data transmission slot 10 succeedingly. Thus, a monitor station 1 acquires the state change data of all stations by the polling of each occasion periodically and easily obtains the detailed polling of the designated station.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a satellite ground station monitoring system, and in particular, to a satellite ground station monitoring system that is used with a satellite line and has a function of collecting detailed data of a specific station in addition to status change data of each station. Regarding ground station monitoring method.

2. Description of the Related Art Conventionally, in this type of satellite ground station monitoring system, detailed data was collected from all stations each time, or only state change data of each station was collected by polling.

Problems to be Solved by the Invention However, the conventional satellite ground station monitoring system described above has the following drawbacks.

(1) When collecting detailed data from all stations every time,
Each station has a large amount of data, and it takes time to collect and process it afterwards.

(2) When collecting only the state change data of each station by polling, it is necessary to send a request command again to the specific station to obtain detailed data, and if multiple state changes occur, It takes some time to return to the original polling state.

The present invention has been made in view of the above-mentioned conventional situation,
Therefore, an object of the present invention is to eliminate the various disadvantages inherent in the conventional technology, and to make it possible to monitor the status changes of all stations in a short time and collect detailed data of a specific station in parallel. The objective is to provide a new satellite ground station monitoring method.

Means for Solving the Problems In order to achieve the above object, the satellite ground station monitoring system according to the present invention includes a polling slot for transmitting a polling command from a monitoring station within a control frame on a satellite line;
It is configured with a status change response slot for transmitting status change data of each station, and a detailed data transmission slot for a specific station to transmit detailed monitoring data of its own station to a monitoring station.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a satellite ground station monitoring system according to the present invention.

Referring to FIG. 1, the monitoring station 1 periodically sends out reference polling (Polling) 6, and in this polling signal 6, the ID of the monitored station requesting return of detailed data is included in the control frame 5. Code included.

Each of the monitored stations (A) 2 to (N) 4 sends state change data to a predetermined position within the state change response slot 9.
the first! Station A (in the 1Jflj frame and station N in the next frame) continues to send out its own detailed data to the detailed data transmission slot 10.

In addition to being able to regularly obtain status change data for all stations through polling every time, the monitoring station 1 can also easily obtain detailed data for a designated station.

As described in detail, according to the present invention, in addition to the normal polling of state change data, it is equipped with a detailed data collection function using the detailed data transmission slot provided in the control frame. This provides the advantage of being able to collect detailed data on a specific station in parallel while monitoring the status changes of all stations.
