摘要
为解决水下通信双方位置不确定时的短距离通信问题,设计并实现了一种采用磁耦合技术的水下非接触式收发装置,该非接触磁耦收发装置采用ASK调制方式发送,包络检波解调,并利用C8051F020来抑制自发自收现象从而实现半双工通信。实验表明:该收发装置成本低廉,简单便携,功耗低,实际应用性强,可以有效解决水下短距离非接触式通信问题。
In order to solve the problems of short-range underwater communication while the position of two sides are uncertained,a non-contact transceiver devices for underwater which is based on magnetic coupling technology is designed.The transceiver device sent by ASK modulation mode,demodulated by envelope detector,C8051F020 is used to suppress the phenomenon of self-transmitting and self-receiving in order to achieve half-duplex co-communication.The experiment shows that the transceiver device is not only low cost,simple and portable,but also low power consumption,and it has a strongly practical application by effectively resolving the non-contact short-range underwater communications.
