(论文)摘要随着单片机功能的日益完善,粮食检测的实时性、准确性也越来越高。寻找最佳配置和最好的性价比成为粮情检测研究的重点。针对传统粮库检测系统的不足,本文设计了一款能对粮库环境进行实时检测的智能巡检小车。巡检小车系统由接收板和小车两部分组成。小车采用 STC12C5A60S2单片机作为控制核心,由 DHT11 温湿度传感器、MQ-2 烟雾传感器、避障循迹、HC-05 蓝牙模块等主要模块组成。同时接收板以 STC89C52 为控制核心,搭配报警模块、HC-05 蓝牙模块、LCD1602 液晶显示模块。将小车采集到的温湿度信号送入单片机进行处理,经单片机处理后的数据通过蓝牙传输给接收板,接收板单片机将接收数据进行模数转换,转换后的数值通过 LCD液晶屏显示。实现温湿度烟雾的采集显示、检测报警功能。与传统环境检测系统相比,具有低功耗、使用方便、移动与定点采集相结合的特点。- I -关键词: 粮食;单片机;温湿度烟雾;巡检小车;检测报警(论文)AbstractWith the improvement of the function of single-chip microcomputer, the real-time and accuracy of grain detection is also higher and higher. To find the best configuration and the best cost performance ratio has become the focus of the research of grain situation detection. In view of the shortcomings of the traditional grain depot detection system, this paper designs an intelligent patrol car which can detect the grain depot environment in real time.The inspection car system consists of two parts: receiving board and car. STC12C5A60S2 single chip microcomputer is used as the control core of the car, which is composed of DHT11 temperature and humidity sensor, mq-2 smoke sensor, obstacle avoidance tracking, hc-05 Bluetooth module and other main modules. At the same time, STC89C52 is the control core of receiving board, which is equipped with alarm module, hc-05 Bluetooth module and LCD1602 LCD module. The temperature and humidity signals collected by the car are sent to the single-chip microcomputer for processing, and t...
