Redundant smog detector and system

Abstract

The invention belongs to the fire alarm detection technology field and provides a redundant smog detector and a system. The redundant smog detector comprises controllers connected with a power source portion, a code receiving portion and a code returning portion, wherein the controllers comprise a first controller and a second controller, the first controller is connected with a first smog sensing portion, and the second controller is connected with a second smog sensing portion; for the system, the redundant smog detector is in hitched with a bus, the bus is connected with a first general controller and a second general controller, the first general controller comprises a first system control portion and a first code transceiving portion, the second general controller comprises a second system control portion and a second code transceiving portion, and the first code transceiving portion and the second code transceiving portion are respectively connected with the bus. According to the redundant smog detector and the system, problems that multiple complex conditions can not be satisfied by a smog detector in the prior art, a damage rate is high, service life is short, error reports constantly occur, detection precision seriously decreases as time goes by, and the system facing various situations can not work normally are solved.

Description

technical field [0001] The invention belongs to the technical field of fire alarm detection and relates to a smoke detector with redundant functions and a smoke detection system with double and multi-level redundant functions. Background technique [0002] Smoke detector, also known as fire smoke alarm, smoke sensor, smoke sensor, etc. At present, fire detectors are mainly divided into four categories from the physical and chemical process of detection: smoke-sensitive type, temperature-sensitive type, light-sensitive type (flame detection type), and gas-sensitive type (CO, etc.); in order to improve the accuracy of the alarm and reduce false alarms, On this basis, a composite detector combining smoke sensing, temperature sensing and light sensing gas has emerged. From the detection range of fire detectors, there are mainly two types: point type and linear type. Point type fire detectors use a small sensor to respond to solid or liquid particles suspended in the surrounding...
