Monitoring method

Abstract

The invention relates to a monitoring method. The monitoring method comprises the steps that (1), a monitor system is provided and comprises n ion type smog sensors, n pyroelectric infrared sensors, m image analysis devices and a main processor, wherein m is smaller than n, n and m are natural numbers greater than one, the ion type smog sensors correspond to the pyroelectric infrared sensors one to one, one image analysis device corresponds to multiple ion type smog sensors and multiple pyroelectric infrared sensors, the main processor is connected with the n ion type smog sensors, the n pyroelectric infrared sensors and the m image analysis devices, and on the basis of a detection result of the multiple ion type smog sensors and the multiple pyroelectric infrared sensors corresponding to the image analysis devices, the image analysis devices are controlled to be switched on and switched off; (2), the monitor system is used for monitoring.

Description

technical field [0001] The invention relates to the field of target area monitoring, in particular to a monitoring method. 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.
