摘要
采用抗干扰能力比较强的FSK技术构成感应通信系统,利用耦合线圈来实现钻杆之间的无线通信,钻杆内部采用同轴电缆传输信息,这样可以获得较高的数据比特率。本文以AT89C51单片机为控制系统,设计了一套可以实现双向通信的FSK系统,并测试了该系统的可靠性以及误码率。
This paper uses FSK technique which has strong ability of anti-interference to construct the induction communication system. Coupling coils are used to realize the wireless communication between the drills, and coaxial cables are used to transmit signals in the in- ternal of drill pipes,so high data bit rate is got in this way. In this paper, a two-direction communication FSK system is designed using AT89C51 rnicrocontroller as control system,and the reliability and error rate of this system are tested.
