The invention provides an atmospheric microorganism laser detection alarm system comprising a laser output device, a collection device, a detection device, a gathering device and a processing device, wherein the laser output device is used for generating 355nm pulse laser beams to induce NAD(P)H and riboflavin in microorganism to separately generate fluorescence signals; the collection device is used for receiving and transmitting the fluorescence signals; the detection device is used for converting the fluorescence signals into electrical signals; the gathering device is used for gathering the electrical signals; and the processing device is used for processing and analyzing the electrical signals. According to the atmospheric microorganism laser detection alarm system based on 355nm laser provided by the invention, air microorganism aerosol within a range of 150m in the morning and at night in an unknown area can be detected and alarmed by reasonably selecting component technical parameters and types; the system is light in weight and convenient to move and arrange, has the advantages of being real-time, stable, reliable and high in sensitivity, and can be applied to the fields of public security, epidemic prevention and environment monitoring, with wide market prospects.

The invention provides a connecting rod appearance size detection system. The appearance size detection system comprises a feeding mechanism, a carrying mechanism, a moving mechanism and a laser detection system. The feeding mechanism is connected with the moving mechanism through the carrying mechanism, and the laser detection system is arranged on the moving mechanism. The invention further provides a detection method of the connecting rod appearance size detection system. Through cooperative use of the moving mechanism and the laser detection system, the size, defect detection and characterrecognition of a connecting rod can be efficiently and accurately detected. A plurality of supporting pieces are inserted into two symmetrical clamping grooves. The number and mounting positions of the supporting pieces can be freely adjusted to adapt to connecting rods of different sizes, and the connecting rods are placed on the supporting pieces. The number of the supporting pieces only needsto stably support the connecting rods, the supporting pieces do not need to be laid in a large-area piece-by-piece mode, and therefore material cost is saved, and detection of a follow-up laser detection system cannot be affected.
