摘要
提出了一种以LPC2294和AD7895芯片为核心的船用智能IO设备模数转换系统,并从硬件接口电路和软件设计方法两部分对该系统进行了详细介绍。相较于传统的基于AD7656芯片的模数转换系统,文章提出的设计方法功耗低、采样精度高、硬件电路更为简单,更加适用于船舰空间狭小、高温湿热的环境特点。
A novel analog-digital conversion system of marine intelligent I0 equipment based on LPC2294 and AD7895 chip is proposed. The system is introduced from two aspects, the hardware circuit and the software design. Compared with the traditional system based on AD7656 chip, the system proposed in this paper has lower power consumption and simpler hardware circuit, which is more suitable for narrow, hot and humid environment on ships.
