红外避障机器人毕业设计方案.doc

摘要 伴随红外物理和技术不停发展, 红外探测技术已广泛地应用于军事、煤矿安全生产等各个领域。把目标或目标区域红外辐射聚焦在探测器上红外接收光学系统基础作用, 通常情况下其结构类似于一般接收光学系统, 但因为工作波段为红外波段, 其光学材料和镀膜必需和它工作波长相匹配。 针对题目标要求，我们设计了一款简易红外避障小车。电路设计关键有以下四个模块：传感器模块（红外发射和接收器），控制模块（AT89S52），实施模块（伺服电机），电源模块。传感器模块关键经过对左、右红外传感器信号分别进行采集，传送给控制模块。控制模块对采集来信号进行处理，做出比较后把控制信号传送给实施模块。 配合正确软件设计，小车能够在设计赛道中正确快速地完成行走任务。 关键词： 红外； 避障； 传感器 Abstract All bodies has its own infrared radiation characteristics. For studying the various objects of infrared radiation, people use ideal─absolute blackbody radiation body (hereinafter referred to as in bold) the benchmark. Can absorb all the incident radiation and not the reflection of the object is called in bold. Good absorber must have also been good radiation body, so the blackbody radiation efficiency is highest, the radiation rate than a 1. Any real objects of radiation emission quantity and the same temperature blackbody emission of quantity of launch than, called the object than radiation rate, its value is always less than 1. The object than radiation rate, and the material object types, characteristics, temperature, surface other factors, such as the wavelength. According to the topic request, we design a simple infrared obstacle avoidance of the car. The circuit design basically has the following four modules: sensor module (infrared transmitter and receiver), control module (AT89S52 devices), executive module (servo motor), power supply module. Sensor module mainly through to the left and right of the infrared sensor signal, respectively the collection, transfer to the control module. Control module to the acquisition of signal processing, make more the control after signals to execute module. The software design includes basic car to walk, walk, the combination of infrared obstacle avoidance program design, such as walking strategy improvement, through to the infrared signal processing to achieve the best car walk path. Cooperate with the right software design, the car can in the design of the track accuratel
