摘要
基于STC89C52单片机设计一种专用鸟声录制系统。该系统用于在野外放置在鸟巢中录制成年鸟和幼鸟的叫声,用单片机控制录音的程序,为便于后续处理,滤声模块过滤掉低频噪声,TCS510M1⁃D28录制模块把鸟的叫声录制下来并以无损格式保存到存储卡中,采用红外感应模块来检测鸟是否在鸟巢中,当鸟进入,则开启,否则关闭。通过实验样机测试结果表明,用无损格式保存的音频文件中的鸟叫声还原性高,系统的能耗低,续用时间长,可满足长时间野外鸟巢中的录制要求。
A special birdsong recording system based on STC89C52 is designed.The system is used to record the calls of adult birds and baby birds in the bird′s nest placed in the wild.The single chip microcomputer is used to control the recording program,the sound filtering module is utilized to filter out the low⁃frequency noise for the convenience of subsequent processing,and the TCS510M1⁃D28 is used to record the birdcall and save it to the memory card in undamaged format.The infrared sensing module is used to detect whether the bird is in the nest.When the bird enters,it will be opened;otherwise it will be still kept closed.The testing results of the experimental prototype show that the birdcall in the audio file saved in lossless format has high reducibility,and the system has low energy consumption and long endurance,which can meet the requirements of a long⁃time record in the bird′s nest in the wild.
