Tide level data transmission system based on Beidou satellite communication

Abstract

The invention relates to a tide level data transmission system based on Beidou satellite communication. The tide level data transmission system based on Beidou satellite communication comprises a conventional tide reporting station and a conventional tide reporting data receiver, and further comprises a tide level data collecting and sending device used for receiving messages of the conventional tide reporting station, a Beidou satellite used for transferring the messages of the tide level data collecting and sending device, and a tide level data receiving and transferring device used for receiving the messages transferred by the Beidou satellite, wherein the tide level data receiving and transferring device sends the tide level messages to the conventional tide reporting data receiver in a wireless mode. On the premise of not damaging a transmission process blueprint of an existing ship automatic tide level reporting system, the characteristics of reliability, weather resistance and long distance of navigation data transmission of the Beidou satellite are utilized and combined with an original tide level transmission mode, only functional devices with the continuing and filling properties are used, and then tide level data can be effectively transmitted to the areas where a traditional wireless data transmission board cannot cover.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, in particular to a tidal level data transmission system based on Beidou satellite communication. Background technique [0002] At present, the tide level information that dredger operations rely on comes from wireless base station signals. This model based on "wireless data transmission board" has been used for many years. The theory is reasonable and the equipment is reliable. , dredging, dredging, and gradually infiltrate into the practical activities of various dredging ships. The types of ship operations and the scope of activities are expanding day by day, and the requirements for the amount of data information and its accuracy, continuity, and stability are also increasing. Therefore, , by increasing the height of the antenna erection, the service area provided (about a dozen kilometers) is already stretched, and coupled with factors such as electromagnetic wave interference...

[0002] At present, the tide level information that dredger operations rely on comes from wireless base station signals. This model based on "wireless data transmission board" has been used for many years. The theory is reasonable and the equipment is reliable. , dredging, dredging, and gradually infiltrate into the practical activities of various dredging ships. The types of ship operations and the scope of activities are expanding day by day, and the requirements for the amount of data information and its accuracy, continuity, and stability are also increasing. Therefore, , by increasing the height of the antenna erection, the service area provided (about a dozen kilometers) is already stretched, and coupled with factors such as electromagnetic wave interference in the working frequency band, some operating ships with self-propelled capabilities are usually subject to conventional digital transmission. The limitation of distance has become the bottleneck of many factors such as expanding the operating area, improving data accuracy, and enhancing system stability and reliability.
