Problems solved by technology

At present, there are some dust concentration detection instruments in the domestic market, but most of these instruments do not provide real-time network alarm function, which is not conducive to the unified monitoring and management of dust concentration detection by the government, and the effect is very limited.

Embodiment Construction

[0025] In order to further set forth the characteristics of this patent, further description is given below.

[0026] The design of this system is mainly dust detection and alarm nodes, each node is composed of 5 modules, namely sampling module, data processing module, liquid crystal display module, wireless module and alarm module.

[0027] Among them, the sampling module chooses the dust sensor GP2Y1010AU0F produced by Sharp Company. The sensor is small and light, has a small working current (not exceeding 20mA), low power consumption, and a long service life of about 5 years. In this sensor, an infrared light-emitting diode and a phototransistor are arranged diagonally to allow it to detect the refracted light of dust in the air, and use it to judge the dust content in the air. The sensor can detect very small dust particles, and the smallest dust particle diameter that can be measured is 0.8 microns. Its output is an analog voltage proportional to the measured dust concen...

Abstract

The invention relates to a dust detection system, and in particular relates to a detection alarm system which can concentrate the situations of different detection points in one same area. The dust detection alarm system provided by the invention aims to relatively accurately measure the dust concentration inside different industrial buildings and rapidly make an alarm to operators working in the industrial buildings when the measured concentration value exceeds a concentration value which may cause an explosion. The dust detection alarm system mainly comprises dust detection alarm nodes and two stages of background monitoring alarm systems, and three stages of alarm to industrial buildings, factory security monitoring departments and town security monitoring departments can be made. Full-direction multi-stage real-time accurate dust concentration detection and alarm can be achieved indeed, and thus the safe production of factories is ensured.

Description

technical field [0001] The invention relates to a dust detection system, in particular to a detection and alarm system that can concentrate the conditions of different detection points in the same area. Background technique [0002] On August 2 this year, Jiangsu Kunshan Zhongrong Metal Products Co., Ltd. encountered a fire source due to excessive dust concentration, which caused a huge explosion. This sounded the alarm for us to prevent disasters caused by excessive dust concentration. [0003] Dust explosion refers to the fact that dust within the explosion limit range encounters a heat source (open flame or high temperature), and the flame spreads instantly throughout the entire mixed dust space, producing a very fast chemical reaction and releasing a large amount of heat at the same time, forming a very high temperature and a large explosion. The pressure of the system converts the energy of the system into mechanical work as well as radiation of light and heat. Explos...
