surveillance system

Abstract

The invention relates to a monitoring system. The monitoring system comprises n ion type smoke sensors, n pyroelectric infrared sensors, m image analysis devices and m host processors, wherein the m is less than the n; the ion type smoke sensors are in one-to-one correspondence with the pyroelectric infrared sensors; one image analysis device corresponds to a plurality of ion type smoke sensors and a plurality of pyroelectric infrared sensors; the host processors are connected with the n ion type smoke sensors, the n pyroelectric infrared sensors and the m image analysis devices respectively; on the basis of testing results that each image analysis device corresponds to the plurality of ion type smoke sensors and the plurality of pyroelectric infrared sensors, the opening and the closing of each image analysis device are controlled; through the monitoring system provided by the invention, fire hazards and inbreak conditions within a target area can be automatically detected; moreover, according to the fire hazards or the position where inbreak takes places, a nearby image analysis device can be controlled, so as to automatically rotate to the corresponding direction. Therefore, the flame grade can be analyzed and the monitoring images of inbreak can be collected.

Description

technical field [0001] The invention relates to the field of target area monitoring, in particular to a monitoring system. Background technique [0002] Due to the large amount of precious metals used in the alloy factory area, especially some rare metals, the price is expensive, so it needs to be monitored to prevent criminals from entering, and to avoid losses caused by fire and smoke spread. [0003] However, in the target area monitoring system in the prior art, the smoke, temperature or combustible gas sensors for fire monitoring and the infrared sensors for intrusion alarm are arranged separately, and there is no centralized management, and the flame level in the event of a fire cannot be identified. At the same time, a camera is installed at each monitoring point in the target area. The camera is generally turned on 24 hours a day, and the intrusion generally only occurs at a certain period of time at a certain monitoring point, which leads to a large waste of camera ...

[0003] However, in the target area monitoring system in the prior art, the smoke, temperature or combustible gas sensors for fire monitoring and the infrared sensors for intrusion alarm are arranged separately, and there is no centralized management, and the flame level in the event of a fire cannot be identified. At the same time, a camera is installed at each monitoring point in the target area. The camera is usually turned on 24 hours a day, and the intrusion generally only occurs at a certain monitoring point for a certain period of time, which leads to a large waste of camera resources.
