At present, the industry of digital and intelligent products is used more and more widely, data acquisition, transmission, analysis and application is particularly important, how to avoid the disadvantages of acquisition equipment interface to a single, fixed function, poor practicability, using ARM embedded computer module M9080-N20 as the foundation, using the VK3266 chip UART serial interface,the analog communication based on 73K222AU modem and HR219307 transformer is introduced, the transformer collector can realize analog communication based on second tier, and supports Ethernet, CAN bus and UART serial communication, can effectively solve the remote data acquisition, data transmission and control, is suitable for the special environment of equipment fault detection, diagnosis and repair. The experimental results show that the intelligent data acquisition system not only has the fault diagnosis device can realize various functions; rapid field communication network, the data of different types of equipment remote collection, transmission, analysis and control functions, and has wide application prospect and practical value in the integration of military and civilian products.
