Research and Practice of Data Collector Device |

Abstract: | 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 73K222AU,HR219307 transformer to realize analog signal long-distance transmission and data acquisition;user-defined protocols and integrated algorithm in software design can expand the function of analog communication based on 73K222AU 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. |
