Technical Field
The invention relates to the technical field of energy storage station fire fighting, in particular to a multi-stage linkage energy storage fire fighting control method and system.
Background
Smoke detectors have been used in homes for many years. Recently, as home appliances become more intelligent, so does smoke detectors. Today, homes have traditional smoke detectors using ionization detectors, and also use intelligent systems of ionization detectors and connect to home routers. However, there are still some problems with conventional smoke detectors and intelligent smoke detectors.
First, in order for a smart detector to send a fire alarm beyond its audible range, it typically requires a network connection through a wireless router. However, if the smoke detector is far from the router, it may not be able to connect. Some smart devices have a wired connection. However, if a fire begins on a wall or room remote from the smoke detector, the wired connection may often be broken before the smoke detector detects the fire.
Second, information in the network is passed through routers (and modems) to the internet. If a fire destroys the router and/or modem (if separated), the intelligent smoke alarm will be isolated from potentially important information.
Referring to a system and a method for realizing data transmission of a smoke detector from the smoke detector, which are disclosed in chinese patent publication No. CN111344756A, the conventional smoke detector and temperature measuring equipment cannot find out the hidden danger of electrical fire in time due to the factors of low sensitivity, late alarm time, easy environmental influence on detection, and the like.
