Title:
FIRE EXTINGUISHING SYSTEM AND FAULT DETERMINING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/017059
Kind Code:
A1
Abstract:
A fire extinguishing system, comprising a control module (110), at least one battery (120), and at least one fire extinguishing module (130). Each fire extinguishing module (130) is communicated with one or more batteries (120); when the temperature of the battery (120) connected to a first fire extinguishing module (130) is greater than or equal to a temperature threshold, the fire extinguishing module (130) extinguishes the fire by releasing a fire extinguishing agent into the battery (120) on fire; the first fire extinguishing module (130) is any one of the at least one fire extinguishing module (130); the control module (110) is used for obtaining a pressure value in the first fire extinguishing module (130), and when the pressure value in the first fire extinguishing module (130) satisfies a preset condition, generating alarm information indicating that a fault occurs to the first fire extinguishing module (130) or the battery (120) connected to the first fire extinguishing module (130). The fire extinguishing system can improve the precision of fire extinguishing for batteries (120) in a cabinet, identify a fault cause and a fault position, and improve the operation and maintenance efficiency.
