Problems solved by technology

[0003] However, field devices will be interfered by debugging signals, jitter signals, and fast action reset (or over-limit reset) signals during daily use, that is, field devices will frequently change their status between normal and abnormal when they are disturbed.
According to the existing field equipment status abnormality alarm judgment method of the automation system, the interference signal will cause the automation system to frequently and erroneously generate a large number of equipment abnormality alarms in a very short period of time, resulting in false alarms
The automation system generates a large number of false alarms, which will affect the normal use of the automation system by users and affect the monitoring of field equipment by users. It is very likely that the truly useful abnormal alarms of equipment will be covered by false alarms, and real-time monitoring of real faulty equipment will not be possible. Monitoring, reducing the ease of use, reliability and stability of the system

Abstract

The invention discloses a method for preventing real-time system false alarm. An automation system is adopted in the method, wherein the automation system designs a temporary cache region, the automation system designs an equipment state variable, and the automation system designs the retention time of the temporary cache region. The method comprises the following steps that the automation systemacquires the equipment state; the automatic system records the equipment state in the temporary cache region, and the equipment state record storage duration of the temporary cache region is the retention time of the temporary cache region; the automation system records the latest state of the equipment in the equipment state variable; after the timing of the temporary cache region is finished, the automatic system compares the value in the temporary cache region with the value of the equipment state variable; and an equipment alarm is generated. The retention time of the temporary cache region is 5 seconds, and a temporary cache region state retention timer is designed by the automatic system.

Description

technical field [0001] The invention relates to the field of rail transit automation, in particular to a method for real-time system alarm and false alarm prevention. Background technique [0002] There are many automation systems in the field of rail transit, which are used to realize the monitoring and control functions of on-site equipment. Typical rail transit automation systems include ISCS (Integrated Supervisory and Control System, integrated monitoring system), PSCADA (Power Supervisory Control And Data Acquisition system power monitoring system), BAS (Building Automatic System, environment and equipment monitoring system), etc., one of the core functions of these automation systems is to monitor the status of on-site equipment, and when the status of the on-site equipment is abnormal, it will give a real-time alarm to remind users to pay attention to the abnormality in time Equipment, quickly repair equipment failures, and minimize the adverse consequences caused by...
