捕捉移动光源机器人设计与制作 ———信号处理及执行 郭正祥 摘 要：目标定位技术是一项光、机、电、算相结合的实用技术，在很多领域都有应用。课题分为信号采集及传动和信号的处理及执行两个部分。本文阐述的是后半部分：系统采用AT89S52单片机作为整个系统的控制核心，控制ADC0809模数转换器把前端送来的含有移动光源位置信号的模拟信号转换成数字信号，然后用单片机对数字信号进行解析、运算等处理，计算出光源位置的坐标，并通过数码管驱动电路控制数码管显示光源所在位置的坐标值。如果被锁定目标的锁定时间超过10S（该时间可根据需要任意设置），则启动以语音芯片ISD1420为核心的报警系统，完成语音报警与警示。系统的软件和硬件采用模块化设计思想，采用C51语言编写程序。系统实现了光、机、电、算一体化，具有体积小、造价低、追踪的自动化程度高，有一定的稳定性，具有初步的人工智能，位置误差不大于10％。 关键词：移动目标；捕捉；A/D转换；单片机；定位；报警 The design and production of the robot to capture the mobile light source ——the processing and execution of the signal Guo Zheng-xiang Abstract ：It is an item of light, machine, electricity that the goal orients technology, be regarded as the practical technique that combines together, there is application in a lot of fields. The subject is divided into two parts of signal gathering and processing and execution of transmission and signal. What this text explained is the latter half: The system adopts AT89S52 one-chip computer as the control core of the whole system, control ADC0809 modulus converter contain, move whom front send here light source position analog signal of signal change into a digital signal, go on analyze, operation,etc. deal with with one-chip computer to digital signal, calculate the coordinates of the position of light source, and is in charge of the number and urge the circuit to control the coordinate value that numbers are in charge of revealing the position of light source. Exceed 10S (can arbitrary to set up according to need in this times) locking time to lock goal, start the warning system taking chip ISD1420 of the pronunciation as the core, finish the pronunciation to call the police and warn. Systematic software and hardware adopt module design philosophy, adopt C51 language to write the procedure. The system has realized all, machine, electricity, calculating that integrates are small, the fabrication cost is low, the automatic intensity followed the trail of is hig
