摘　　要：针对目前数据采集设备接口单一、功能固定、实用性差等缺点,采用ARM嵌入式工控模块为基础,研究支持以太网、CAN总线、UART串行接口、二线MODEM模拟通信的数据采集器,在硬件设计上采用MODEM芯片73K222AU、HR219307变压器实现模拟信号远距离传输和数据采集;在软件设计上实现用户自定义协议和集成算法,可以有效解决多功能多接口数据采集、传输和控制。实验结果表明,该研究能实现以太网、CAN、UART、二线模拟信号等数据采集和数据转发功能,具有很强的实用价值。Since currently data collector has some defects,such as interface is single,function is fixed,and practicability is poor,and a new collector is proposed,which is based on ARM built-in industrial control module,and can support Ethernet,CAN bus,UART serial interface,and the data collector having two lines MODEM analog communication. The hardware design uses MODEM chip 73K222 AU,HR219307 transformer to realize analog signal long-distance transmission and data acquisition; userdefined protocols and integrated algorithm in software design can expand the function of analog communication based on 73K222 AU modulator-demodulator, resolving effectively the problems of multifunctional data collection,transmission,and control with multi-interface. The experimental results indicate that this type of product can implement the data collection and transmission function of Ethernet,CAN,UART and two lines MODEM analog signal. Consequently,it has very strong practical values.
