Embodiment Construction

[0019] The present invention will be further described below.

[0020] A method for counting the number of alarms in a security monitoring system, comprising the following steps:

[0021] Step 1: Set a time limit value;

[0022] Step 2: When the value measured at a certain moment exceeds the threshold value, record the moment, and calculate the total time period sum during which the value measured in real time exceeds the threshold value from this moment to the following time limit value period;

[0023] Step 3: Set a percentage, and calculate the ratio of the total time period and the time limit value in step 2. When the ratio exceeds the percentage, it is considered that the value is abnormal during this period, and it is counted as the number of alarms; otherwise, it is not statistics.

[0024] There will still be deviations in the statistical method of this embodiment. For example, a certain company’s gas leaks cause the concentration to exceed the threshold far, and las...

Abstract

The statistical method of safety supervision system alarm numbers comprises the following steps of step1, setting a time limit value; step2, when a value measured at one moment exceeds a threshold, recording the moment, and in a time period from the moment to the later time limit value, calculating the total time period sum of the values which exceed the threshold through real-time measurement; and step3, setting a percentage, calculating the ratio of the total time period and the time limit value in the step two, when the ratio exceeds the percentage, considering that the value in the time period is abnormal and calculating as one alarm number; otherwise, carrying out the operation that the number is not counted. In the invention, repeated statistical alarm numbers can be greatly reducedand the validity of the alarm numbers is increased.

Description

technical field [0001] The invention belongs to a safety monitoring system and relates to a method for counting alarm times of the safety monitoring system. Background technique [0002] The core objective of the major hazard monitoring and monitoring system is to implement and strengthen the technical means for the safety supervision department to implement and strengthen the responsibility of the main body of enterprise hazard monitoring. The construction of a major hazard source monitoring system is not a simple solution to how to connect the enterprise video signal and data signal to the safety supervision unit to realize the signal viewing function, but the key is to solve how the safety supervision department uses this system to realize the major hazard sources and on-duty monitoring of the enterprise. Functions such as dynamic supervision, early warning and disposal, data trend analysis, and record of violations such as room, instrumentation status of major hazard sou...
