多传感器障碍物检测系统的软件设计
 
摘要:本设计较详细地介绍了一种多传感器障碍物检测系统的软件设计。该系统以单片机为核心,通过检测微波雷达探测器的信号来适时地启动温度传感器、速度传感器、超声波传感器等。对这些传感器输出值的检测量化,得到距离、速度、温度等值。通过合理的计算,把这些变量因素组合在一起,对各种数据进行修正补偿,得出比较精确的结果。论文描述了系统研制的理论基础,多个传感器功能结构,以及使用性能优良的AVR单片机ATmega8L对系统所起的积极作用。论文概述了几种检测技术的发展现状及基本原理,介绍了ATmega8L单片机及其各主要寄存器的功能特点。针对检测系统的测距、测温、测速、显示、报警、补偿修正等部分的软件设计方案进行了论证与设计。

The software design of Multisensor obstacle detected system
 
Abstract: the software design about the system of a multi-sensor obstacle detecting has been introduced detailly in this design. the system is cored of SCM, and initiates the temperature sensor, speed sensor and ultrasonic sensors at the appropriate time by detecting the signal of microwave radar detector. Having gotten the distance, speed, temperature by checking and measuring the output of these sensors. And have the accurate results by calculating reasonably, compounding these variables together, and amending and compensating the various data that. The paper has described the theoretical basis of the developed system, the function structure of several sensors, and the active role played by the use of the excellent performance of the AVR ATmega8L. The paper has outlined the development and the basic principles of several the detected technology, and introduced the ATmega8L microcontroller and the function features of its register. the verification and design have been made according to the software design scheme about detecting the location, temperature, speed, display, alarm, compensation and amendment of the system.
 
Key words: Radar Detection, Temperature Detection, Speed detection, Ultrasonic detection, ATmega8L
