Abstract

PURPOSE:To relieve the processing load of a HOST station and a transmission time by allowing a master station to have a data base for all slave stations, revising a data of all the slave stations at a prescribed period, and sending only a fault data to the HOST station. CONSTITUTION:A master station 2 sends polling to slave stations 3, 4 for each prescribed time, compares it with a data of the data base for all the slave stations possessed by its own master station 2 at present, and when the collected data differs from its own data possessed, the state change data is sent to the HOST station 1. The master station 2 uses the state change data to revise the data base for all slave stations. Then the HOST station 1 revises all the slave station data base depending on the status change data sent from the master station 2, issues a command to the slave stations 2, 3 via the master station 2 to collect the present status data of an electric communication system and executes the return. Thus, the processing time is reduced and the processing load of the HOST station is relieved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a monitoring and control method for a telecommunications system, and in particular to a plurality of slave stations that individually monitor and control each part of a telecommunications system, and a method for controlling the slave stations. The present invention relates to a supervisory control system that includes a master station that collects data from the slave stations, and a host (HO8T) station that receives data from the slave stations from the master station and constructs a database regarding all the slave stations.

(Prior Art) Conventionally, in this type of supervisory control method, the slave station receives status change data (hereinafter referred to as commonly referred to) by polling from the master station.
Only the status change data (hereinafter abbreviated as "condition change data") was sent back to the master station, and the master station transmitted the status change data sent from the slave stations to the HO9T station. In the supervisory control method, even if there is a communication failure in the telecommunications system that is subject to supervisory control, current data and 8037
It is necessary to avoid inconsistencies with the station's database for slave stations.

Figure 3 shows a flowchart of data update processing using the conventional supervisory control system. Send it to HO3T station 1, and after receiving this current data, HO3
T station 1 updates its own database for all slave stations,
A mismatch between the slave station data of HO8T station 1 and the current status of the slave station was prevented.゛So HO8T station 1
In order to process the collected data in a short time, a large computer with high processing power is required.

(Problems to be Solved by the Invention) In the conventional supervisory control system described above, all data of all slave stations are managed on the HO3T station side.

Therefore, all alarms, including unused alarm points, are transmitted to the 8037 station, and the HOST station must perform all processing. Therefore, if the processing power of the 8037 station is low, it will take a very long time to process all the alarms.

Furthermore, an attempt to shorten the processing time requires an expensive high-speed computer.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides means in which a plurality of slave stations that monitor and control a telecommunications system are subordinate to a master station through telecommunication lines. This master station is connected to the 8037 station via another communication line,
A supervisory control system is constructed by this 8037 station collectively controlling the plurality of slave stations via the master station; upon receiving polling from the master station, each of the slave stations connects to the telecommunications system. The normal data and status change data that occur are detected and sent to the master station, which collects these data and sends them to the HO8T station, and this 8037 station receives these data. A supervisory control method for monitoring and controlling the telecommunications system by updating a database of all slave stations provided by the master station and sending commands to the plurality of slave stations via the master station, wherein the master station It has a database of all slave stations, collects data of all slave stations at regular intervals, updates the database of all slave stations it owns, and sends only status change data from the current data to the 110 ST station. After receiving this status change data, the 8037 station updates its own database of all slave stations, and sends a command to the plurality of slave stations via the master station to monitor the telecommunications system. It is characterized by control.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block circuit diagram showing one embodiment of the present invention, and FIG.
The figure is a flowchart illustrating data update processing performed in this embodiment.

In the embodiment shown in FIG. 1, the HO3T station 1 and the master station 2 are connected by a communication circuit 5, and the slave station 3.4 and the master station 2 each connect to another communication circuit 6.7. Connected via. The HO3T station 1 and the master station 2 are each equipped with a Kaneko station database and its update function, and together with the slave station 2.3, construct a supervisory control system to monitor and control the telecommunications system.

The master station 2 sends slave stations 3, 4, . The T station 3.4 sends polling to collect the current data detected by the T station 3.4, and compares it with the data in the database for all slave stations currently held by the master station 2 itself. If so, the status change data is transmitted to the HO3T station 1. The master station 2 also updates its own database for all slave stations using this status change data. Then, the HO3T station 1 updates its own database for all slave stations using the status change data sent from the master station 2, and also updates the slave stations 2.3 through the master station 2.
It sends commands to collect and return current data on the telecommunications system. Thus telecommunication lines 5.6.7
．． A supervisory control system constructed from all the slave stations 3, 4, the master station 2, and the HO3T station 1 ensures complete supervisory control of the telecommunications system.

(Effects of the Invention) As described above, in the present invention, the master station has a database of all the slave stations, and the master station updates the data of all the slave stations at regular intervals. By transmitting only the abnormal data to the HO3T station, the transmission time and processing load on the HO8T station can be reduced, so a small computer can be used for the HO8T station. As a result, a supervisory control system equivalent to the conventional system can be constructed at a low cost.The present invention has such an effect.
