寻呼应答式电浮标内既有发射器(FSK)又有接收器(AM),平时AM接收机处于低功耗待机模式,当母船想查询某一电浮标的位置时,向该电浮标发送特定的寻呼码,当电浮标收到母船寻呼信号后,识别母船身份,在母船身份正确情况下,即启动FSK发射机,通过短波天线将电浮标当前的位置信息和状态信息发回母船,从而使母船实时并便捷地跟踪定位到当前电浮标的位置和状态信息,并达到省电、隐蔽性好、防盗、可靠性高的目的。 The page response type electric buoy has both a transmitter (FSK) and a receiver (AM). Usually the AM receiver is in a low-power standby mode. When the mother ship wants to check the position of an electric buoy, it will send the specific paging code to electric buoy, when the electric buoy receives the paging signal from the mother ship, it will identify the mother ship's identity. If the mother ship's identity is correct, the FSK transmitter will be activated, and the current position information and status information of the electric buoy will be sent back to the mother ship through the short wave antenna , So that the mother ship can track and locate the current position and status information of the current electric buoy in real time and conveniently, achieving the purposes of power saving, good concealment, anti-theft and high reliability.
