A system and method for remotely connecting and transmitting tide level signals using Beidou satellites

Abstract

The invention discloses a system for remotely connecting and transmitting tide level signals by using Beidou satellites. The satellite communication receiver and data transmission station at the receiving end of the marine ship, the satellite communication transmitter and the satellite communication receiver have built-in CPU and memory. The satellite communication transmitter receives the signal from the automatic tide reporting station, and after processing the signal containing the tide level information Send to the Beidou satellite system; the satellite communication receiver receives the signal containing the tide level information from the Beidou satellite system, and after processing, transmits the tide level signal to the tide level receiver through the digital radio station. The invention also discloses a method for remotely connecting and transmitting tide level signals by using Beidou satellites. The invention can add a new transmission system on the basis of the existing automatic tide reporting system of ships, and use the Beidou satellites to transmit tide level signals accurately and reliably.

Description

technical field [0001] The invention relates to a tide level signal transmission system and method, in particular to a system and method for remotely connecting and transmitting tide level signals using Beidou satellites. Background technique [0002] At present, the tide level information that dredger operations rely on comes from the wireless base station signal, that is, the tide level remote reporting station transmits the tide level information to the tide level receiver at the receiving end of the ship through radio waves. This mode based on "wireless data transmission board" has been applied. For many years, the theory is reasonable and the equipment is reliable. However, with the development of the industry, the expansion of longer distance channels, dredging, and dredging have gradually penetrated into the practical activities of various dredging ships. The types of ship operations and the scope of activities are expanding day by day. For signal The requirements for...

[0002] At present, the tide level information that dredger operations rely on comes from the wireless base station signal, that is, the tide level remote reporting station transmits the tide level information to the tide level receiver at the receiving end of the ship through radio waves. This mode based on "wireless data transmission board" has been applied. For many years, the theory is reasonable and the equipment is reliable. However, with the development of the industry, the expansion of longer distance channels, dredging, and dredging have gradually penetrated into the practical activities of various dredging ships. The types of ship operations and the scope of activities are expanding day by day. For signal The requirements for the amount of information and its accuracy, continuity, and stability are also increasing day by day. Therefore, it is impossible to expand the service area (about a dozen kilometers) by increasing the height of the antenna erection. For some operating ships with self-propelled capabilities, they are usually limited by the transmission distance of conventional digital transmission waves. Due to the limited signal transmission and reception, the tide level receiver at the receiving end of the ship receives inaccurate information, and the received signal is stable and reliable. Poor performance, making it impossible to expand the operating area
