基于GPRS的智能垃圾满溢报警系统设计

摘要

针对城市中垃圾箱满溢后导致垃圾大量堆积及二次污染等问题，设计了一种基于GPRS的智能垃圾满溢报警系统，用于实时监测垃圾箱满溢状态。该系统利用垃圾对红外线光束是否遮挡在光电传感器产生电平变化的原理检测垃圾满溢状态，并通过MCU驱动GPRS模块自动向指定人员发送垃圾箱是否满溢的相关短信，通知相关人员及时清运垃圾。实验结果和现场应用效果表明，该系统能准确检测垃圾满溢状态，报警信息发送及时，极大地提高了垃圾清运工作效率，有效地解决了垃圾堆积造成的二次污染等问题，对智能城市建设有重要意义。%In view of the problems of garbage accumulation and secondary pollution after garbage can overflowing, a GPRS-based spill-over warning system of intelligent garbage can was designed to monitor the state of garbage can in real time. It uses IR-photoelectric sensor as the garbage detection element and uses GPRS module to send massage and indicate whether the can is spill over or not through MCU, so as to notify the relevant personnel to remove garbage timely. Experiment and application results show that this system can detect the state of overflowing accurately and send massage in time, greatly improve the working efficiency of garbage removal and solve the problem of secondary pollution. The system has significance to construction of smart city.
