The beacon machine is converted into power supply voltage required by each part of circuits through the power supply module, the control module adopts a low-power-consumption circuit, the pressure sensor is used as a pressure switch to sense water pressure change, the water pressure is reduced after the equipment floats upwards, and the beacon machine is electrified and starts to work. The beacon machine starts the Beidou module at regular intervals to obtain positioning information, the coordinate position of the equipment is sent to the receiving device through short message data communication, the receiving device sends out an acoustic signal report after receiving a target signal through positioning software, the software can indicate the relative position and the distance between the receiving device and the target, and an operator determines a recovery scheme according to the field condition.
Beacon machine design based on iridium satellite system has been made in central laboratory of electronic testing technology of north and middle university. The iridium satellite number transmission platform sends the received GPS positioning information to a gateway station processing server through an iridium satellite network system, and after receiving the SBD message, the server generates an E-mail according to the IMEI in the SBD and sends the E-mail to a designated electronic mailbox. Receiving information in form of attachments in mailboxes
