Problems solved by technology

It should be said that the occurrence of pneumoconiosis can be controlled by monitoring the dust concentration in the working environment of enterprises according to my country's current health standards. However, due to the backwardness of monitoring methods and technologies, it is impossible to collect real-time data on dusty workplaces.

Embodiment Construction

[0033] The invention will be further explained with reference to the drawings

[0034] figure 2 It is the block diagram of the dust sampling and separation module. The dust sampling and separation module is one of the key technologies of the present invention. The module consists of a micro cyclone separator (2-1), a sampling flow sensor, an air pump, a dust collector, a flow control circuit, and a signal conditioning circuit ( figure 2 ) And other components.

[0035] The mini cyclone separator separates the dust particles in the air into two parts, one part is respirable dust, 7 2 Dust particles above μm, Figure 7-1 versus Figure 7-2 It is its implementation structure diagram. The separator must meet the following four optimal size conditions:

[0036] (1) The width of the air inlet is equal to the width of the annular gap between the inner and outer cylinders

[0037] B=

[0038] The above formula, D c Is the diameter of the outer cylinder (Figure 7), do is the diam...

Abstract

The invention provides an intelligent sensor capable of monitoring respirable dust, relating to an intelligent sensor which is used for detecting dust concentration of a high-concentration dust operating environment and carrying out acquiring and remote monitoring networking in real time. The intelligent sensor comprises a dust sampling separating template, an infrared monitoring module, an RAM (Random Access Memory) microprocessor module, a communication module and a power supply module. The intelligent sensor can be used for acquiring dust data in industrial and mining enterprises and detecting the operating environment. Aiming at the current situation and the demand of dust monitoring in the industrial hygiene field in China, the dust sensor is designed, thus the technical blank of thefield is made up, and an advanced detection technology is provided for the security control department.

Description

Technical field [0001] The invention relates to an intelligent sensor used in a high-concentration dust working environment to detect environmental dust concentration, real-time collection, and remote monitoring and networking, and belongs to the technical field of industrial environment detection. Background technique [0002] In recent years, my country’s safety production situation is not optimistic. Major accidents have occurred from time to time, causing huge economic losses and social impacts to the country and society. Then, the death toll from pneumoconiosis in the occupational health field also showed an upward trend in another hard-hit area for production safety. The degree of harm of pneumoconiosis is to some extent greater than work-related fatalities. Dust workplaces in our country are very common, especially the dust hazards of mining enterprises and building materials enterprises are very serious. Pneumoconiosis patients are the most in the world. Although my co...
