Inland shore-based AIS (Automatic Identification System) ship data wireless transmission device and transmission method

Abstract

The invention relates to an inland shore-based AIS (Automatic Identification System) ship data wireless transmission device and a transmission method. The device comprises a communication antenna, a solar cell panel, a storage cell, a GPRS communication module, an AIS data filtering module, an AIS shore-based receiver, a protection box and a support rod. The communication antenna, the solar cell panel and the protection box are fixed on the support rod. The storage cell, the GPRS communication module, the AIS data filtering module and the AIS shore-based receiver are fixed in the protection box. The connection is that the storage battery is unidirectionally connected with the GPRS communication module, the AIS data filtering module and the AIS shore-based receiver. The AIS data filtering module is bidirectionally connected with the GPRS communication module and the AIS shore-based receiver. The GPRS communication module is connected with the communication antenna through a radio frequency cable. The solar cell panel is connected with the storage cell. The technical effects are that redundant AIS message information can be filtered, the wireless transmission efficiency is improved, the public network transmission costs are reduced, and the device and the method are especially applicable to remote inland waterway regions in which AIS standard base stations cannot be applied due to the fact that there is no infrastructure such as a basic power supply and the internet.

Description

technical field [0001] The invention relates to an AIS base station for data transmission, in particular to an inland river shore-based AIS ship data wireless transmission device and transmission method. Background technique [0002] AIS (Automatic Identification System) general automatic identification system is a new application system that appears with the development of information technology industry. At present, the system is more and more widely used in the field of inland ship monitoring. Compared with the centralized monitoring of port ships, the monitoring difficulty is more complicated due to the variety of geographical terrain in the inland river basin. In order to achieve seamless coverage of AIS signals throughout the watershed, it is often necessary to set up AIS base stations in many areas that lack power supply and wired transmission networks, which brings difficulties to the use of existing AIS standard shore-based systems.

AI Technical Summary

Problems solved by technology

At present, the system is more and more widely used in the field of inland ship monitoring. Compared with the centralized monitoring of port ships, the monitoring difficulty is more complicated due to the variety of geographical terrain in the inland river basin.

In order to achieve seamless coverage of AIS signals throughout the watershed, it is often necessary to set up AIS base stations in many areas lacking power supply and wired transmission networks, which brings difficulties to the use of existing AIS standard shore-based systems

[0003] In addition, the amount of data transmitted by the existing AIS base station is relatively large. When the data is transmitted through the public wireless network, due to the billing mode of the public network based on data traffic, high communication costs will be generated at this time, and the data transmitted by the base station contains A large amount of message information that has nothing to do with ship monitoring. It is absolutely necessary to filter the information when the communication resources are tight.

In particular, remote inland waterway areas where the AIS standard base station cannot be used due to the lack of infrastructure such as basic power supply and the Internet, which affects the effective monitoring of ships
