摘要
目前国内城市草坪绿化面积不断扩大,但由于存在频繁践踏草坪的现象,城市草坪已经被造成了较为严重的破坏。本文介绍了一种利用热释电红外传感器设计的草坪保护系统,当有人进入草坪时将发出警告,若不听警告继续践踏草坪,系统将对人进行喷水惩罚,以此达到保护草坪的作用。文中也简要介绍热释电红外工作原理。实验证明该系统具有一定的适用性。
At present, the area of city lawn in our country is continually on the rise. But due to the serious situation of frequent trample on the lawn, severe destructions have been taken place on the city lawn. This article describes a lawn protection system based on the pyroelectric infrared. When someone gets into the lawn, the system will issue a warning and if the person continues to trample on the lawn disregard of the warning, the system will punish the person by spraying water on him or her, achieving the target of lawn protection. Besides, the article also briefly describes the working principle of pyroelectric infrared. The experimental results show that the system has the practical value.
