Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] Such as figure 1 As shown, the self-developed Beidou communication and positioning terminal is integrated into the underwater robot control system. The Beidou communication and positioning terminal is composed of a module and an external antenna. It uses the Beidou RDSS large data volume reliable communication and positioning method to integrate its own observation data and positioning information. Send to the Beidou shore-based center. The shore-based center is composed of multiple Beidou communication arrays and Beidou communication base stations. The Beidou communication base station controls the two-way reliable communication of a certain amount of data between the communication array and multiple terminals. Bandwidth, to achieve real-time acquisition of ocean observation and positioning data by underwater robots through communicati...

Abstract

The invention discloses a Beidou communication and positioning system for an underwater robot, and the system consists of a Beidou positioning communication terminal and a shore-based ship-based center, and the positioning communication terminal provides a high-reliability Beidou positioning and communication function based on a Beidou RD/RN core chip with autonomous intellectual property rights,and the system has the characteristics of miniaturization, low power consumption and the like. The shore-based center is composed of a Beidou communication base station and a Beidou communication array. And the Beidou communication base station controls the Beidou communication array to carry out data communication with each terminal, and provides a standardized service interface to the outside through a network or a serial port and the like. The system can establish an RDSS reliable data communication link between a plurality of Beidou positioning communication terminals and a center, and transmits observation and positioning data of a plurality of underwater robots to a shore-based ship-based monitoring center in real time, thereby realizing domestic controllability of communication positioning of marine observation equipment.

Description

technical field [0001] The invention relates to the field of communication and positioning of underwater robots, in particular to a Beidou communication and positioning system for underwater robots. Background technique [0002] China's BeiDou Navigation Satellite System (BDS) is a global satellite navigation system developed by China itself. It can provide all kinds of users with high-precision, high-reliability positioning, navigation, and timing services around the clock and around the world, and has short message communication capabilities. The Beidou terminal refers to the use of the Beidou satellite navigation system for positioning and navigation. Terminal equipment, but the existing Beidou RDSS communication and application terminals have the following problems in transmitting data: [0003] 1. The existing Beidou RDSS can only send about 78 bytes at a time, and there is a certain probability of packet loss. For a large amount of data, packet transmission is require...
