针对海洋石油勘探的需求,设计了电缆定深装置,其采用了基于FSK的感应通信系统。系统地介绍了感通信的发展状况及其基本原理,重点阐述FSK调制解调模块所选用的XR2206和XR2211芯片。感应通信作为水下非触通信方式之一,以其功耗低、尺寸小、制作简单等特点必将得到越来越广泛的应用。 In response to the demand of offshore oil exploration, a cable depth setting device is designed, which uses an induction communication system based on FSK. Systematically introduced the development of sense communication and its basic principles, focusing on FSK modem module selected XR2206 and XR2211 chip. Induction communication, as one of the underwater non-touch communication methods, will be more and more widely used because of its low power consumption, small size and simple manufacture.
