Bioaerosol laser monitoring and early warning and identification device and method

Abstract

The invention relates to a bioaerosol laser monitoring and early warning and identification device, which comprises a monitoring unit, a sampling unit, an identification unit and a total control unit. The monitoring unit monitors bioaerosol in the environment and distinguishes non-bio-particles and bio-particles in the air to obtain a bio-particle concentration, and transmits the bio-particle concentration to the total control unit. The total control unit controls the working state of the monitoring unit, the sampling unit and the identification unit respectively, when the bioaerosol concentration monitored by the monitoring unit reaches an early-warning threshold, the total control unit sends an early-warning signal, and at the same time triggers the sampling unit in terms of starting collection of bioaerosol samples. The device provided by the invention can accurately identify the varieties of bioaerosol, quickly identify the varieties of bio-particles, and has the advantages of short identification time and high accuracy.

Description

technical field [0001] The invention relates to the field of bioaerosol monitoring and early warning, specifically, a device and method that can not only perform bioaerosol monitoring and early warning, but also have the function of quickly identifying the type of the monitored bioaerosol. Background technique [0002] With the improvement of living standards and the increasingly serious pollution of the living environment, people pay more and more attention to the air quality in the activity area, and some pathogenic microorganisms in the air are the focus of people's attention. In some places with high air quality requirements, such as clean rooms, operating rooms, pharmaceutical workshops, etc., the monitoring of air quality is particularly important. Not only that, since the United States was attacked by anthrax in 2001, countries have paid more attention to the monitoring and early warning of bioterrorism attacks. Therefore, in order to promote social harmony, improve ...

Problems solved by technology

Therefore, the system has disadvantages such as complex structure, bulky size and high cost, which is not conducive to the integration and miniaturization of the whole system

[0007] 3) The detection unit of the prior art uses a CCD imaging and signal processing system to detect the sample liquid to obtain the detection result, but it does not indicate that the type of biological particles can be distinguished

This method has a long detection cycle and inevitably has a certain false recognition rate and rejection rate.
