Abstract

PURPOSE:To improve the system reliability by providing two sets of alarm parts having a switching means, respectively for stopping the transmission to each module at the time when its own operation abnormality is generated, and also, starting the operation of its own first and second communication means at the time when the other transmission stop is detected, together with a first and a second communication means. CONSTITUTION:Usually, only one of alarm parts 1, 2 collects the alarm of each module P1... Pk, and also, executes an alarm transfer to a network 3. In such a state, when the alarm part 1 causes operation abnormality at a certain time point, the alarm part 1 stops a polling signal for an alarm collection to each module P1 - Pk. The alarm part 2 detects a fact that an output to each module P1 - Pk is stopped, from a terminal f1 which is executing a receiving operation, and judges that the alarm part 1 is abnormal. In accordance there with, the alarm part 2 starts to execute an access of the network 3 and each module P1 - Pk instead of the alarm part 1. In such a way, the alarm collection/ transfer function is maintained.

In the alarm collection and transfer method, the first and second communication means together with the first and second communication means stop transmitting to each module when an abnormality occurs in their own operation, and when the transmission stop of the other is detected, the first and second communication means themselves It is equipped with two alarm units each having a switching means for starting the operation.

〔実施例〕〔Example〕

次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

第１図は、本発明の一実施例を示すブロック図である。FIG. 1 is a block diagram showing one embodiment of the present invention.

It has means for switching the transmission output terminal to the reception operation terminal.

For example, when the alarm unit 1 is performing alarm collection and transfer, the output terminal f2 to each module P0 to PK of the alarm unit 2 operates as a reception terminal. Thereafter, if the alarm unit 1 malfunctions at a certain point, the alarm unit 1 stops sending polling signals to each module P1 to PK for collecting alarms. The alarm section 2 detects from the terminal f2 performing the receiving operation that the output to each of the modules P1 to PK of the alarm section 1 has stopped, and thereby determines that the alarm section 1 is abnormal. In response, the alarm unit 2 starts accessing the network 3 and each of the modules P1 to PK in place of the alarm unit 1. That is,
Terminal f2t - used for transmission to each module P1 to PK for alarm collection, and terminal TN is connected to network 3
Start using it for sending to. The alarm section 1 has a terminal f1
performs a receiving operation to monitor the output of the alarm section 2, and all transmissions to the network 3 are also stopped.

一方、アラーム部２がアクセス権を有する時にアラーム
部２に異常が発生した場合には、上記と全く同様にして
、アラーム部１ヘアクセス権が移る。On the other hand, if an abnormality occurs in the alarm section 2 while the alarm section 2 has the access right, the access right is transferred to the alarm section 1 in exactly the same manner as described above.

したがって、アラーム部１および２のどちらか一方のみ
が正常でｓｂさえすれば、警報収集転送機能も正常に働
く。Therefore, as long as only one of alarm units 1 and 2 is normal and sb is performed, the alarm collection and transfer function also works normally.
