[Abstract]:With the rapid development of electronic technology, embedded system has become a hot spot, a large number of applications in industrial equipment and household appliances. Nowadays, photoelectric detection technology is developing towards miniaturization, intelligence and high efficiency. Non-contact measurement is one of the main contents of detection technology. In this paper, AVR is used as the main controller of laser scanning detection system, which combines scanning detection technology with computer technology. By controlling the scanning optical system, the photoelectric receiver, the electronic processing system and the computer processing system, the beam carrying the information of the radial diameter of the workpiece is received, converted and processed. Thus, the radial dimension of the workpiece is measured. In this paper, the miniaturization and intelligent design of scanning detection system is realized from the embedded aspect. The detection principle and method of laser scanning detection system are discussed in detail. The scanning speed of rotating mirror is analyzed, and the scanning beam is shaped and designed. At the same time, the circuit and software of the laser scanning detection system are designed. It can be seen from the experimental results that the error of the detection system designed in this paper is within 鹵2 渭 m.
