本论文基于AT89C51单片机设计了一款智能无感杂物桶，其设计思路是利用定时器计数与下降沿外部中断配合其他模块进行协同。在自动翻盖方面采用的是热释电红外传感器被动检测来控制电机翻盖。HC_SR04超声波测距模块用来检测杂物装载程度，将检测出来的数据通过LCD1602液晶显示以此实现超声波测距显示功能。通过RS485通讯将检测的数据传递至上位机，使人能够实时监测杂物桶装载程度。
Based on the AT89C51 single-chip microcomputer, this thesis designs a smart non-sense clutter. The design idea is to use the timer to count and the external interrupt of the falling edge to cooperate with other modules. In the automatic flip, a pyroelectric infrared sensor is used to control the motor flip. HC_SR04 ultrasonic ranging module is used to detect the loading level of garbage, and the detected data is displayed on the LCD1602 to realize the ultrasonic ranging display function. The detected data is transmitted to the upper computer through RS485 communication, enabling people to monitor the loading level of the debris bucket in real time.
