【Abstract】 According to the national criterion for testing shock-resisted eye protection device established by the National Standard Bureau, the shock tester for eye protection device has been introduced in this paper, which can reliably and precisely test the safety capability of eye protection glasses or masks. The system principle and the designs of launching installation , hardware and program flow diagram of signal processing device based on AT89C51 and CPLD, have been presented. Finally experiment results approve that the apparatus can well meet the expected requirement and criterion.更多还原
