METHOD FOR SOUNDING OR STOPPING SIMULTANEOUSLY ALARM BUZZERS IN FAULT MONITORING SYSTEM

摘要

PURPOSE: To prevent enlargement of a fault scale and a fall of service by sounding or stopping simultaneously all alarm buzzers of a control monitor and a subordinate monitor, when a fault of a device to be monitored is generated, or when an arbitrary monitor alarm buzzer stop switch is depressed by a maintenance person or an alarm buzzer circuit switch is depressed. ;CONSTITUTION: At the time of fault of one group of device groups 21, 22 and 23 to be monitored, for instance, the device group 22 to be monitored, a control monitor 9 receives fault information through a communication control part. Also, in the case of fault of the device group 21 or 23 to be monitored, fault information from a subordinate monitor 101 or 102 is received through the communication control part. Subsequently, when it is detected that the fault is generated, in the case an alarm buzzer circuit switch of a memory is turned on, a sounding instruction is executed to an alarm buzzer 52, and simultaneously therewith, the sounding instruction is executed to alarm buzzers 51, 53, as well of all the subordinate monitors 101, 102 and the alarm buzzers of all the monitors sound simultaneously. Also, in the case of fault by an operation of a maintenance person, the buzzers of all the monitors are stopped simultaneously.;COPYRIGHT: (C)1994,JPO&Japio
