Abstract

The invention discloses a biological particle detection system based on a gelatin detection baseband. The system comprises a sealed dark chamber, a detection box, an air path system, an optical system, a photoelectric conversion module, and an air extracting pump, wherein the sealed dark chamber is provided with an air outlet, the detection box is arranged inside the sealed dark chamber, and comprises a baseband coated with gelatin, and a baseband driving device, the air path system is provided for collecting and ejecting aerosol biological particles, the optical system comprises a LED light source and an optical lens, and is provided for aerosol biological particle monitoring analysis, the photoelectric conversion module is provided for photoelectric conversion, and the air extracting pump is provided for generating negative pressure in the sealed dark chamber. With the nozzle of the air path system, the aerosol biological particles are ejected on the baseband coated with the gelatin to form a circular aerosol biological particle sample spot for detection, the baseband driving device drives the baseband to convey the sample spot to a fixed monitoring point, the probe of the optical lens completes data acquisition of the biological particle characteristics of the sample spot. The system has the following advantages that: the control precision is high, the detection result has high reliability, the monitoring can be continuously performed for not less than 70 hours, the system is convenient to use, and the like.

Description

technical field [0001] The invention relates to a biological particle detection system based on a gelatin detection baseband. Background technique [0002] In the atmospheric environment on which human beings live, there are various biological particles, which are usually invisible to the human eye or unperceivable by the sense of smell. This is true even for biological particles that are hazardous to humans. The frequency of biological weapons is gradually increasing around the world. How to discover the existence of biological particles in the shortest possible time, so as to achieve timely detection and timely defense is the key to minimize the loss. [0003] The two biggest problems faced by aerosol particle detection are how to collect aerosol particles in the air and how to monitor whether these particles belong to biological particles in the shortest time. A commonly used system is to use a sampler to concentrate the aerosol particles and inject them into a specifi...
