摘要
根据国家标准计量局制订的防冲击眼护具试验方法的国标要求 ,提出一种眼护具冲击测试仪的研制方案 ,实现对防护眼镜和防护面罩的安全性能进行可靠精确的检测。文中具体阐述了系统工作原理 ,发射装置设计 ,及基于单片机加CPLD双片结构的信号处理装置硬件设计和程序流程。
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.
