摘要
针对人行径方向测量的红外探测系统需求,提出了实现多通道模数转换器(ADC)的一种新方法,采用了双片可独立工作的带有8通道ADC的单片机,基于双片单片机之间的SMBus通讯可实现16通道ADC系统,从而可简化后端处理电路,提高系统的数据处理能力,并取得较好的数据采集的同步性。
A new approach used to implement multi-channel ADC used in infrared detection system of people moving direction monitoring is proposed. The 16-channel system is implemented based on the SMBus communication of double MCU with 8-channel ADC which can works independently The experimental results show that the proposed technology simplifies circuit and enhance the capabilities of data-processing, having a better synchronization of data acquisition. The foreground of the method is broad.
