Method and system of locating beacon by using phases

Abstract

The invention discloses a method and a system of locating a beacon by using phases. The system comprises the beacon and a receiver. The beacon comprises a radio station used for transmitting radio wave signals, a controller used for controlling the working of the radio station, and a power supply management module used to supply the controller and the radio station with power. Whether the radio station is electrified by the power supply management module is controlled by the controller. The receiver comprises more than three antennas, a signal source used for transmitting fixed-frequency signals S, a mixer used for the mixing processing of the radio wave signals and the fixed-frequency signals S received by the antennas, a low pass filter used for the filtering processing of the signals after the mixing processing, and a measuring chip used for measuring time differences. The system provided by the invention is advantageous in that only the radio station is required, and no GPS modules are required, and the radio station is only required to be switched on for a little while (smaller than 0.1s) during the use, and is used to transmit the small segment of the radio wave signals, and therefore power consumption is small; only the radio station is required, and no GPS modules are required, and therefore only one antenna is required, and the size of the system is reduced.

Description

technical field [0001] The invention belongs to the field of marine detection equipment recycling, in particular to a phase positioning beacon method and system in the field. Background technique [0002] The 21st century is the century of the ocean. To develop and protect the ocean, we must first understand the ocean. People detect the ocean gradually from the near sea to the deep sea. Many of the ocean detection equipment need to be sunk into the seabed and recovered for research after working for a period of time. During the process of equipment surfacing, due to the influence of ocean currents, the location of the surface and the location of delivery There are often gaps, which, combined with the impact of the waves, often make equipment difficult to find. In order to improve the recovery rate of marine equipment, it is often necessary to bind a beacon device to the detection equipment. The beacon device can provide its location information (such as GPS information). Ba...

Problems solved by technology

[0008] This method requires the beacon to be in a standby state all the time, waiting for a signal from the receiver, which consumes a lot of power, may cause unexpected failures during long-term operation, and has poor stability.
