摘要
、光电感应模块、电机驱动模块和语音报警模块等功能模块组成,以超声波传感器、RPR220光电传感器和单片机为核心,通过传感器采集距离信息,再经过A/D转换让单片机发出指令,如果超声波传感器检测到人与垃圾箱的距离小于设定距离,则垃圾箱自动翻盖,如果RPR220光电检测到垃圾箱已满,、性能稳定、操作方便、低成本、智能化等优点,为进一步隔离人与垃圾,防止人感染细菌找到了一个可行的解决方法.

Title A Multifunctional Bin Control System
Abstract:
This paper designs a multifunctional bin control system based on STC89C52RC. The cores of this system are ultrasonic sensor, RPR220 photoelectric sensor and single chip puter (SCM). It consists of power circuit, sensor circuit, clock circuit and voice alarm module, etc. Using the sensor to collect distance information, then the information is to be conversed by A/D, causes the SCM issues an instruction. If the ultrasonic sensor detects that the distance between people and dustbin is smaller than set distance, dustbin lid would open automatically. If RPR220 photoelectric detects that dustbin is chock-full, the system would issue a voice message. This system has advantages of simple structure, stable performance, convenient operation, low cost and intelligentization. And would realize automatic flip of dustbin, voice prompt of dustbin being chock-full and regular spraying disinfectant. Thus it is a feasible method pletely isolate people and rubbish, and prevent people from infecting with the bacteria on garbage.
Key terms: single chip puter, Ultrasonic sensors, RPR220 photoelectric sensors, dustbin

社区即是公共场所,又不同于一般的公共场所,,垃圾桶所收容的垃圾多半为饮料瓶和一些纸类等固体物品,,社区垃圾桶设计显然没有考虑到地域性的特点,在社区内安放的是一般公共场所所
