[Abstract]:Scraper conveyer is one of the necessary equipments in coal mining face, and it is very important to run safely and reliably. Based on the inspection standard of scraper conveyer in China and coal industry, the virtual instrument of scraper conveyor performance testing is developed, and the error analysis and performance evaluation are carried out. The research and development of this instrument will play an important role in accurately detecting and evaluating the performance of scraper conveyer and ensuring the safe and efficient production of coal mine. The main contents of this paper are as follows: (1) by studying and analyzing the main performance parameters and measuring principle of scraper conveyor, the main parameters such as power, chain speed of scraper, noise, static stretch length of circular chain and so on are determined. The sensor needed for scraper conveyor detection is selected and the testing method is determined in combination with the actual situation. The USB6221 of NI Company is selected as the data acquisition equipment and the corresponding signal conditioning circuit is designed. The portable virtual instrument hardware platform based on USB bus is constructed. Aiming at the static characteristic test of circular chain, an automatic detecting device with single chip microcomputer as its core is designed and developed. The device can work independently and on top, and under different working modes, such as the cooperation of lower computer and so on. (2) LabVIEW is used as the software development platform. The testing software of the whole machine performance of scraper conveyor is designed and developed. The functions such as the power of the head and tail motor, the chain speed of the scraper, the running noise, the data processing, the storage, the management and the report generation are realized. The communication with the lower computer, the calculation and analysis of the measurement data, the storage and display programs are written for the static performance detection of the circular chain. This paper uses C language to compile the loop chain performance test, and communicates with the host computer, etc., studies and analyzes the types, causes and correction methods of the virtual instrument error, and corrects the hardware and software error of the tester. The static characteristic analysis and function experiment of the virtual instrument for measuring the performance of scraper conveyor are carried out. The results show that the virtual instrument of scraper conveyor performance detection developed in this paper can meet the functional requirements of scraper performance testing. Compared with traditional testing methods, the degree of automation, detection efficiency and precision are higher.
