Intelligent dust detection system and detection method

Abstract

The invention provides an intelligent dust detection system and detection method, belongs to the technical field of intelligent detection, and is used for solving the shortcomings in the prior art that the inspiration flow quantity is small, inspiration flow is not constant, the sampling error is high and positioning is inaccurate or cannot be performed when GPS signals are weak. The system comprises a core processor, a sampling system module, a gas flow sensor, a GPS positioning module, a GPS assisted positioning module, a wireless data transmission module and a power supply module; the sampling system module, the gas flow sensor, the GPS positioning module, the GPS assisted positioning module and the wireless data transmission module are connected with corresponding signal input/output ends of the core processor through self signal input/output ends respectively. The intelligent dust detection system and detection method provided by the invention have the advantages of large inspiration flow quantity, constant inspiration flow, low sampling error, non-dead zone positioning function and the like.

Description

technical field [0001] The invention relates to an intelligent dust detection system and a detection method, belonging to the technical field of intelligent detection. Background technique [0002] With the advancement of science and technology and the gradual enhancement of human awareness of environmental protection, people's awareness of the hazards of dust has gradually increased. In 1996, my country promulgated the "Hygienic Standards for Respirable Sand Dust in the Air of Workshops" (GB16225-1996), "Hygienic Standards for Respirable Cement Dust in the Air of Workshops" (GB16238-1996) and "Sanitary Standards for Respirable Coal Dust in the Air of Workplaces". "Standard" (GB16248-1996), the implementation of the detection of respirable dust concentration in the workplace [9]. At the same time, various countries are also actively taking measures to explore and research the detection methods of dust concentration, and a variety of dust sampling methods and different types ...

AI Technical Summary

Problems solved by technology

Based on the pump-suction dust detector, the micro-weighing method is used to calculate the dust concentration; in the prior art, the pump-suction dust sampling system has a small suction flow rate (the maximum can reach 20L / min); Constant current is difficult), there are fluctuations in pumping, high sampling error (about 5%) and other shortcomings

At the same time, there are also problems that do not meet the sampling requirements of the national standard; the sampling data cannot be uploaded in real time, and cannot be connected to the Internet; there is no indoor positioning function (some can only use GPS to obtain outdoor positioning function, when the GPS has no signal, the device cannot be positioned) and other problems.
