摘　　要：喷泉作为城市的点缀如雨后春笋般出现,但是大多数喷泉区域开放程度较高,经常有市民进入喷泉区域内游玩。喷泉喷出的水柱是经过水泵高压输送上来,其压力十分巨大,很容易对人体造成伤害。历年来全国各地已发生多起喷泉伤人事件,也导致很多喷泉被关闭。本装置通过使用单片机以及压阻式压力传感器,结合特定的识别算法,通过判断喷泉上方是否有人踩压,从而实现对水阀的通断,实现保护目的。The fountain is a city＇s embellishment,and has emerged like bamboo shoots,but most of the fountain areas are opento a high degree,causing people to enter the fountain area and play. The water column the fountain ejects is conveyed up throughthe pump under high pressure,with a huge pressure which very easily cause harm to the human body. Over the past years,therehave been a number of fountain injuries across the country,leading to the closure of many fountains. The device operates throughthe use of single-chip microcomputer and piezoresistive pressure sensor,combined with a specific identification algorithm,by judgingwhether someone stamps over the fountain,so as to achieve the water valve turning on and off,to achieve the purpose of protection.
