Description

Riverbank base AIS ship oceangoing ship wireless data transmission device in a kind of

Technical field

This utility model relates to a kind of data transmission AIS base station, particularly to riverbank base AIS ship oceangoing ship wireless data transmission device in one.

Background technology

AIS (Automatic Identification System) general automatic recognition system is as the development of IT industry and the new application system that occurs.This system is more and more extensive in the application in inland navigation craft monitoring field at present, and compared to the Centralized Monitoring of yard craft, owing to the change of interior river valley geographical terrain is various, monitoring difficulty is more complicated.In order to realize the ais signal seamless coverage in whole basin, generally requiring and set up AIS base station in a lot of areas lacking power supply and wire transmission network, this brings a difficult problem to the use of existing AIS standard bank based system.

The data volume of the most existing AIS base station transmission is bigger, when data are by public wireless network transmission data, due to public network charge mode based on data traffic, at this moment high communication cost will be produced, and the data of base station transmission include the message information the most unrelated with ship monitor, these information, in the case of communication resource anxiety, are necessary to carry out data filtering completely.Especially, for want of the infrastructure such as basic power supply and the Internet cannot use AIS standard base station, thus affects the remote cruiseway area of boats and ships effective monitoring.

Summary of the invention

nullThe problem existed in view of prior art，This utility model provides a kind of interior riverbank base AIS ship oceangoing ship wireless data transmission device，Concrete technical scheme is，Riverbank base AIS ship oceangoing ship wireless data transmission device in a kind of，Including communication antenna、Solar panel、Accumulator、GPRS communication module、AIS data filtering module、AIS bank base receiver、Protective housing、Support bar，It is characterized in that: communication antenna、Solar panel、Protective housing is fixed on support bar，Accumulator、GPRS communication module、AIS data filtering module、AIS bank base receiver is fixed in protective housing，It is connected as accumulator unidirectional connection GPRS communication module respectively、AIS data filtering module、AIS bank base receiver，AIS data filtering module is bi-directionally connected GPRS communication module respectively、AIS bank base receiver，GPRS communication module uses radio-frequency cable to be connected with communication antenna，Solar panel is connected with accumulator，Described AIS data filtering module，May filter that the redundancy AIS message information that AIS bank base receiver is exported by serial ports，The frequency by GPRS wireless communication module transmission information can also be controlled.

Of the present utility model having the technical effect that may filter that redundancy AIS message information, improves radio transmission efficiency, reduces public network transmission cost, is particularly well-suited to the infrastructure such as want of basis power supply and the Internet and cannot use the remote cruiseway area of AIS standard base station.

Detailed description of the invention

Accompanying drawing is coordinated to describe in detail below.

nullAs shown in Figure 1，Riverbank base AIS ship oceangoing ship wireless data transmission device in a kind of，Including communication antenna 1、Solar panel 2、Accumulator 3、GPRS communication module 4、AIS data filtering module 5、AIS bank base receiver 6、Protective housing 7、Support bar 8，Communication antenna 1、Solar panel 2、Protective housing 7 is fixed on support bar 8，Accumulator 3、GPRS communication module 4、AIS data filtering module 5、AIS bank base receiver 6 is fixed in protective housing 7，It is connected as accumulator 3 unidirectional connection GPRS communication module 4 respectively、AIS data filtering module 5、AIS bank base receiver 6，AIS data filtering module 5 is bi-directionally connected GPRS communication module 4 respectively、AIS bank base receiver 6，GPRS communication module 4 uses radio-frequency cable to be connected with communication antenna 1，Solar panel 2 is connected with accumulator 3.

AIS data filtering module, may filter that the redundancy AIS message information that AIS bank base receiver is exported by serial ports, it is also possible to control the frequency by GPRS wireless communication module transmission information.

nullAfter inland navigation craft drives to the signal cover of interior riverbank base AIS ship oceangoing ship wireless data transmission device，The boats and ships message that on ship, AIS equipment is launched is received by AIS bank base receiver 6，Owing to ais signal is in transmitting procedure，In order to realize the reliable communication between boats and ships，More identification marking is added in AIS message，Such as heading、Channel number、Serial number、Reserved place、Check bit etc.，Only in the boats and ships ais signal transmitting procedure with AIS base station, there is meaning in these information，And in AIS base station to the transmitting procedure of Surveillance center，Realized by wireless GPRS communication，These AIS identification informations lose meaning，There is no need to be transmitted，Only need to retain the title of boats and ships、Longitude and latitude、Dimension of ship etc. application message，Additionally also can output state message by serial ports in AIS bank base receiver device work process、Longitude and latitude message etc. information，These also can filter，So can filter substantial amounts of redundancy by AIS data filtering module.

AIS data filtering module 5 not only possesses the filtering function of AIS data, the frequency of message transmissions can also be controlled, for the message information repeated, it is possible to reduce the number of times of transmission, the number of transmissions can be increased for some important calling for help information, improve the motility of monitoring.

As in figure 2 it is shown, after AIS data filtering module 5 receives the data that AIS bank base receiver sends over, the most only retain with！AIVDM is the message of beginning, filter out other message unrelated with effective ship information, afterwards message is resolved to plain code by private mark, and store the information such as name of vessel therein, MMSI number, boats and ships longitude and latitude position, if in ten minutes (this time adjustable), have received again same information, the packet filtering these repeated, it is sent to An Ji center, so to reduce repetition, the transmission of invalid information by GPRS module after being compressed by the effective information of this ship after ten minutes.

This device is installed simple and convenient, also can work at shortage electric power, the remote locations of the Internet, after the message received by AIS bank base receiver 6 is processed by AIS data filtering module 5 compression, can be significantly less need for the data volume being transferred to Surveillance center, and then reduce the communication cost produced in GPRS wireless data transmission, in the case of limited construction fund, can set up in two sides, inland river to be monitored and more receive base station, thus the ais signal improving whole basin covers fruit.
