Embodiment 2
Present embodiment discloses a kind of sea area broadband access system of antenna for satellite communication in motion as described in claim 1
System, the information that antenna for satellite communication in motion access system is transmitted according to onboard AIS equipment, instruction identification module and steady control computer, resolves
The direction of antenna rotation and angle out, realize and keep antenna for satellite communication in motion sighting to the base station currently communicated, to protect
Demonstrate,prove communication quality.
Referring to Fig. 2, antenna for satellite communication in motion access system includes that AIS resolves module, instruction identification module and antenna directional angle solution
Calculate module.
Its working principles are as follows:
1) communication antenna that onboard AIS equipment is equipped with by it receives all kinds of AIS information of periphery ship transmission, and
By the AIS information (predominantly VDO message) of itself ship and the AIS information (predominantly VDM information) of periphery ship with a set pattern
Rule is arranged, and is then sent to boat-carrying by serial ports and is surely controlled computer.
2) boat-carrying is surely controlled after the antenna for satellite communication in motion control system in computer receives AIS information, resolves mould by AIS first
Block identifies to AIS information is received, identification content include information checking, information type judgement (only processing AIVDM and
AIVDO information) and information content identification (the only message that processing information content classification is 1,2,3,5,18,19, i.e. ship static state
Information and multidate information).After identification, corresponding information is extracted according to user's ship and the corresponding MMSI code of base station ship, and mention
It supplies antenna directional angle and resolves module.
3) instruction identification module work step, module are extracted according to the classification (bank base base station or boat-carrying base station) of base station
The corresponding information of base station.Bank base base station is such as selected, then corresponding base station position information in database is inquired by base station identity code,
Then it sends this information to antenna directional angle and resolves module；Boat-carrying base station is such as selected, then resolves module to AIS and base station ship is provided
MMSI code, module is resolved by AIS and identifies the corresponding AIS information of base station ship and is resolved, obtains the related letter of base station ship
After breath, sends it to antenna directional angle and resolve module.
4) antenna directional angle resolves module work step, and module is transmitted according to AIS resolving module and instruction identification module
Various information calculates antenna according to parameters such as the position coordinates of antenna current location, ship course, user's ship and base station ship
Steering angle, and control antenna for satellite communication in motion complete turn to.
Feasible, it is as follows that antenna sights workflow,
1) in a certain range, scan for wireless signals is differentiated the maximum intensity of signal by terminal, while identification signal is come
Source, to judge whether the signal of communication of bank base base station can satisfy communicating requirement.
2) such as bank base base station can satisfy communicating requirement, and preferential selection is communicated with bank base base station.Pass through my ship AIS system
The VDO message of system analyzes the motion conditions of my ship, and combines the location coordinate information of bank base base station and my ship antenna for satellite communication in motion
Directional information (being provided by servo-system), calculate the rotational angle of antenna, control antenna servo system, keep antenna always
Towards bank base base station；
3) such as bank base base station is not able to satisfy communicating requirement, then according to scanning result, determines several boat-carryings for being suitble to communication
Base station, and arranged with certain priority, while according to the signal identification information of each boat-carrying base station, being extracted from database
The information such as the identification code (i.e. MMSI code) of corresponding ship；
4) by MMSI code, the AIS static information of ship broadcast, obtains each boat-carrying where receiving and resolving each boat-carrying base station
The installation site of antenna for base station；
5) by MMSI code, the AIS multidate information of ship broadcast, obtains each ship where receiving and resolving each boat-carrying base station
Location information (i.e. longitude and latitude) and operational configuration information (i.e. speed on the ground, course over ground, true course, steering rate etc.)；
6) information obtained according to step 4) and step 5), calculates the rotation angle of antenna, and is transmitted to steady control and calculates
Machine, by surely controlling computer control servo-system, rotable antenna to designated position；
7) it checks communication quality, and by rotating left and right certain angle, determines optimal communication direction.
The base station is locked, implements communication, and simulated simultaneously with other base stations (including boat-carrying base station and bank base base station)
Compare, it is determined whether switch base station in subsequent time.After antenna for satellite communication in motion and control system of the invention, it is capable of forming sea
Upper architectures of communication networks pushes high-speed mobile communications to sea from land, and greatly improves bandwidth, reduce cost of use, subtract
Small communication delay has higher cost performance and better experience sense.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
