るか。When there is a change in the status of the monitoring items 81 to 8n, the monitoring item input section T6 detects the change and assigns a weight to the data processing section 74.
The data is processed in the data storage section 75 and sent to the master station 51 via the communication control section 71, or stored in the data storage section 75 until the sending conditions are met. The master station 51 processes the weighted state change data sent from the slave station at the communication control section 52, receives it at the data processing section 55, and displays it as it is on the transmission display section 57 in the display control section 56.
データ蓄積部５８に蓄積していた。データ処理部５５で

軽い状態変化情報の処理にかかりきりでより重要な状態
変化情報の収集１表示が遅れてしまうという課題があっ
た。In the conventional monitoring control method described above, when the master station collects and displays and records state change information of monitoring items collected and weighted by slave stations, state change information with light weighting occurs frequently. Even if the state change with the heaviest weighting occurs, the master station is busy processing the state change information with the lighter weighting that occurred earlier, and the collection and display of more important state change information is delayed. There was an issue with the problem.
まな、重みの軽重を比較するにあたシ親局の負荷を多大
に増加せしめることと、効果がそれほど期待でき危いと
いう課題があった。However, when comparing the weights, there was a problem that the load on the master station was increased significantly, and the effect was not expected to be that high, which was dangerous.

Slave station data collection control unit 32. The slave station measurement condition (weight) storage unit 331, the weight determination storage unit 36, and the weight determination control unit 38 constitute a communication means in which the communication control procedure described above is variable depending on the weighted state change information monitored by the slave station. There is.
そして、より重い重みづけをされ念監視制御信号を優先
的に通信回線を通すように構成されている。The system is configured so that the psychological monitoring control signal, which is given a heavier weight, is preferentially passed through the communication line.
４１〜４ｎは監視項目である。41 to 4n are monitoring items.
つぎにこの第１図に示す実施例の動作を説明する。Next, the operation of the embodiment shown in FIG. 1 will be explained.

変化情報が送出できる条件が整うまで待つ。Next, in the embodiment shown in FIG. 1, a weight determination control section 38 and a weight determination storage section 36 are added to the slave station, and in addition to the above-mentioned functions, weighting is applied to the communication line between the master station and the slave station. The communication control procedure shall be in the following form. When a state change with a heavy weight (high degree of urgency) occurs, the slave station inquires whether the weight of the state change that has occurred this time is heavy compared to the weight judgment storage unit 36, and if the heavy weights are equal. The state change information of the bus is transmitted to the communication control unit 3 via the data processing unit 34.
1 to the master station 11, and at the same time the weight judgment storage unit 36
It is set so that state change information with a weight below that weight is not sent to the master station. Also, if the weight is light, the data storage unit 3
5 and waits until the weight in the weight determination storage section 36 becomes lighter and conditions are met for transmitting the state change information.

局１１に送出される。Finally, the slave station sends status change information to the master station 11 only when a status change occurs in a monitoring item that has a weight greater than the weight stored in the weight determination storage unit 36, and also sends status change information to the data storage unit 35. The state change data is sent to the master station 11 only when the sending conditions are met.
そして、子局の重み判定制御部３８は一定時間経過後重
み判定記憶部３６にその記憶内容を消去する指令を出し
、通常の状態変化処理に戻る。Then, after a certain period of time has elapsed, the weight determination control section 38 of the slave station issues a command to the weight determination storage section 36 to erase the stored contents, and returns to normal state change processing.
