Graded early warning control fire extinguishing system and method

Abstract

The invention discloses a graded early warning control type fire extinguishing system and method. The system comprises a central processing unit connected with a monitoring module, an acousto-optic alarm module, a video monitoring module, a communication module, a power control module and a fire extinguishing module. The communication module is in remote wireless connection with a control center.The method comprises the steps that a pyroelectric ion detector and a smoke detector detect fire signals; the central processing unit receives detection information of the pyroelectric ion detector and the smoke detector and grades the detection information; the central processing unit controls opening and closing of the monitoring module, the acousto-optic alarm module, the video monitoring module, the power control module and the fire extinguishing module in a graded manner; and an instruction is sent to a control center to enable the control center to perform fire alarm notification. The smoke alarm, the pyroelectric ion detector and the camera are combined to collect fire scene data, grade the collected data through analysis, process the data according to grades and give an alarm, so that resource waste is avoided on the premise that effective fire extinguishing is guaranteed.

Description

technical field [0001] The invention relates to the field of fire early warning, in particular to a fire extinguishing system and method for hierarchical early warning control. Background technique [0002] According to data, the best time to extinguish a fire is within 3 minutes after the fire breaks out. If the fire is extinguished in a scientific way, the economic loss and personal injury can be minimized. Therefore, accurate fire warning becomes the top priority of fire safety. Heavy. Commonly used fire alarm methods are generally divided into regional alarm systems, centralized alarm systems and control center alarm systems. The area alarm system is relatively simple, but it is widely used. The commonly used fire detectors now have a relatively simple detection principle, and the analog quantity transmission changes with the changes of various non-electrical parameters (such as smoke, temperature, etc.). In fact, there are too many uncertainties when a fire occurs, s...
