Alarm system and method based on parameter screening and timing query

Abstract

The invention provides an alarm system and method based on parameter screening and timing inquiring. The alarm system comprises a detector, a judging unit, an alarm database and a wireless alarm module. The wireless alarm module comprises a parameter setting unit, an inquiring unit and a wireless alarm unit. Parameters and threshold ranges corresponding to the parameters in a one-to-one mode are stored in the judging unit. The detector is used for detecting a plurality of parameters in the detecting environment. The judging unit is used for judging whether the values of the achieved parameters are in the corresponding threshold ranges, generating alarm information for the parameters with the values not in the corresponding threshold ranges and storing the alarm information in the alarm database. The parameter setting unit is used for a user to set a plurality of alarm variables. The inquiring unit is used for inquiring whether alarm information corresponding to the alarm variables exists in the alarm database or not once in a while. If the alarm information corresponding to the alarm variables exists in the alarm database, the wireless alarm unit can be used for giving out alarm. The alarm system and method can guarantee the premise of alarm timeliness and can achieve unified monitoring on in-site environments and optionality of the alarm parameters.

Description

technical field [0001] The invention relates to an alarm system and an alarm method, in particular to a wireless alarm system and a wireless alarm method based on parameter screening and regular query. Background technique [0002] At present, in some fields such as nuclear power and banking, in order to ensure the security of their networks, their networks are required to be independent, and outside access to the networks is prohibited. When an accident occurs, how to notify the absent personnel of the abnormality in real time, safely and effectively becomes a problem. A key technical issue. [0003] The existing method to solve this problem is to adopt GSM (Global System for Mobile Communications, Global System for Mobile Communications) wireless alarm technology, and most of the existing GSM wireless alarm technology is to use the combination of GSM alarm host and wireless detector. When the device detects an unexpected situation, the GSM alarm host will send the receive...
