introduction The last time, I introduced the bamboo tube end face detection system based on the industrial computer. This article introduces the development and application of the bamboo tube end face detection system based on the single chip system. The bamboo tube end face detection system based on single chip microcomputer is also an automatic detection system, which can detect the outer diameter, inner diameter, thickness and detection quantity of the bamboo tube. 1, single chip microcomputer Microcontrollers (Microcontrollers) is an integrated circuit chip that uses a very large-scale integrated circuit technology to have a central processing unit CPU with data processing capability, random access memory RAM, read-only memory ROM, various I/O ports and interrupt systems, and timers. Functions such as a counter/counter (possibly including a display driver circuit, a pulse width modulation circuit, an analog multiplexer, an A/D converter, etc.) integrated into a small piece of silicon to form a small and complete microcomputer system in the industry The control field is widely used. 2, system composition The measurement system handled by the single-chip microcomputer is mainly composed of a control box, a probe, a bamboo tube bracket, a liquid crystal screen, a membrane button, and a control/computing circuit system. Its shape and composition are shown in the figure below. The control box is the protective structure of the device, and the scanning laser probe and the single chip microcomputer (control/computing circuit system) are installed in the control box. The bamboo tube bracket is installed at the front of the control box, and the center of the bracket and the control box is provided with a long slot through which the laser beam passes. The upper part of the control box is equipped with a liquid crystal screen, membrane buttons and "emergency stop", "stop" and "start" buttons. The power cord of the system and the lead wire of the foot switch are placed in the lower part of the control box. The setting of the single chip measurement program is operated by the membrane button. 3, system function ◆ Display content: outer diameter, inner diameter, thickness, detection quantity, etc. of the bamboo tube; ◆ Product parameter setting function, which can set the standard value of the inner and outer diameter and thickness of the product and the upper and lower tolerances; ◆ System parameter setting function, can set the serial port, system calibration and calibration, refresh frequency, etc.; ◆ Calibration function: When the measurement error is too large, the accuracy can be restored by calibrating with a calibration rod of known diameter. 4, features ◆ High measurement accuracy. ◆ Fast response, good real-time performance, sampling frequency 200 Hz. ◆ No wear and long service life. ◆ Full digital system, easy to use, easy to operate and easy to maintain. 5, performance indicators ◆ Maximum scanning measurement range: 200mm ◆ Measurement accuracy: wall thickness dimensional accuracy ≤ ± 0. 1mm ◆ Measurement frequency: 200 Hz ◆ Operating ambient temperature: -20 ~ 50 °C ◆ Storage temperature: -25 ~ 75 °C ◆ Laser classification: Class 2 laser products Conclusion The bamboo tube measuring instrument is applied to the detection of the end face of the bamboo tube. The measurement is more convenient and convenient to use. It is a high-precision testing equipment, which can detect various information such as the inner diameter, outer diameter, wall thickness and detection quantity of the bamboo tube, and is used for detecting a large number of bamboo tubes. The homework brings great convenience. In addition to measuring the bamboo tube, the above detection can also be performed on similar round pipe fittings, such as round ceramic cups and pipe fittings. 6.5 Inch Mid-Range Speaker,Ferrite Magnet Midrange,6.5Inch Pro Audio Speaker,6.5 Midrange Speaker Guangzhou BMY Electronic Limited company , https://www.bmy-speakers.com
