基于超声波测距的转台防护系统设计与实现

Design and Implementation of Turntable Protection System Based on Ultrasonic Ranging

针对目前转台的防护措施不完善的现状,设计了一种基于超声波测距的转台防护系统。介绍了超声波测距的基本工作原理,详细叙述了转台防护系统的硬件设计和软件设计。在实验室内完成了测试。测试结果表明,在预先设置的最近30 cm和最远报警距离70 cm处,该系统均能及时触发报警,并切断转台的使能控制按键,保证了测试人员的安全。验证了超声波测距转台防护系统的可行性,为其他转台防护设计提供了技术支持。

Aiming at the current situation of imperfect protection measures of turntables, a turntable protection system based on ultrasonic ranging is designed. The basic working principle of the ultrasonic ranging is introduced.The hardware and software designs of the turntable protection system are described in detail. The testing is completed in a laboratory. Testing results show that the system can trigger the alarm in time at the nearest presented distance of 30 cm and the longest alarm distance of 70 cm, and the turntable′s enable control button is cut off to ensure the safety of testers. The feasibility of the ultrasonic ranging turntable protection system is verified, and technical supports are provided for other turntable protection designs.
