Abstract


Gun Barrel detection method has low efficiency, low accuracy, which restricts the use of artillery equipment efficiency and use of fire performance. The subject of Gun Barrel detection technology, the paper more comprehensive analysis of the development status of the gun barrel at home and abroad detection technology, and discusses the development trend of the gun barrel detection, pointed out that the current the Gun Barrel detection technology to be solve the problem, for these issues paper introduces the gun barrel bore peep calipers systems integrated real-time detection of two functions of the image of the diameter measurement and the inner wall shared with disease, and can predict the remaining life of the gun barrel, the measurement data to the dynamic curve of the form visual display. The system is easy to set up, simple operation, high accuracy, on-site measurement range. Dissertation work includes the following aspects: First, the overall system composition and measurement principle. Its core components include a single-chip acquisition and control device, a sensor with the gun barrel positioning mechanical devices, a computer equipped with a data management and analysis software. SCM Acquisition measuring sensor output voltage and A / D conversion, data storage and display or the serial communication sent to the host computer (computer) data analysis and management, while the image of the gun barrel bore is shown in real time on the monitor screen of the host computer, mechanical device design. The mechanical device accuracy is the main factor affecting the precision of the system. Designed mainly to complete the installation and adjustment of the caliper positioning of the sensor and the image sensor. Each type of artillery matching a caliber adapter ring, in order to achieve a mechanical device is compatible with the requirements of measuring a variety of caliber artillery. , Microprocessor control system design. Design a functional part of the interface circuit and the production PCB printed circuit board, prepared on this basis, the microprocessor control program for debugging, digital capture of the sensor output analog voltage, serial with the host computer (PC) communication and parameter setting function. Fourth, the PC data management and analysis software development. VB and ACCESS database combined with the initial development of the PC data management and analysis software to achieve the basic functions the gun breech read the data, processing and curve of the dynamic residual life prediction of the gun barrel, bore the ablation position of the image Get . System caliper error analysis. From the theoretical analysis of the factors that affect the the diameter measuring accuracy of the system, the analysis estimated the diameter of the measurement error of the system is theoretically less than 0.01 mm. Experimental results show that the system meets the caliper requirements.
