The numerous areas such as woods fire prevention, the mitigation disaster relief and national security are applied, and produce significant economic benefit and social benefit, special
It is not to have played very important effect in Wenchuan County in Sichuan, Yushu district, Qinghai earthquake relief work.
Some disasters occur or case of emergency under, when infrastructure and communications service are destroyed, Beidou CORS
Vehicle can play the advantage of its mobile site, using its included wireless telecom equipment, realize between each CORS vehicle point and
Communicative between CORS vehicle point and headquarter.But due to the limitation of mobile CORS vehicle self-condition, to realize and tradition
3G, the identical transmission of two-way trust data at a distance of 4G communication mode be it is impossible, inevitably there is it is long away from
When from transmission the problems such as transmission failure, transmission error code due to caused by signal fadeout, noise and interference.In general,
Data transmission problems caused by the base station CORS fails without consideration error code as caused by communication link or transmission, because conventional
Communications facility itself has certain error correction or retransmission mechanism.It is limited based on mobile CORS but under disaster or emergency environmental
Communication capacity and one-way transmission limitation, error of transmission will seriously affect the performance of CORS high accuracy positioning service function, when serious
Even result in service failure.The maximum effect of Beidou CORS vehicle can not thus be played.
In order to destroyed in original communications facility or environment without communication condition in, utilize included logical of mobile CORS vehicle
There are under certain error condition, realize the reliable transmission of CORS data, and synthesis as far as possible when letter equipment long range one-way transmission
Consider that CORS vehicle provides the coverage area and economy of service, the invention proposes be suitable for CORS difference based on fault-tolerant encoding
The coding transmission system of location data One-to-All Broadcast.
Summary of the invention
The technical problem to be solved in the present invention is that for the defects in the prior art, providing a kind of applicable long haul communication
CORS data encoding Transmission system, the system by Beidou CORS vehicle and high-power ultrashort wave radio set, and to CORS data into
Row coding, realizes the long range credible delivery of CORS data, reduces the bit error rate of long haul communication.
The technical solution adopted by the present invention to solve the technical problems is: a kind of CORS data volume being applicable in long haul communication
Code Transmission system, comprising:
Mobile Beidou CORS vehicle for receiving data by the Beidou receiver on vehicle, and is sent to CORS service system；
CORS service system, for being grouped to the differential data information in CORS data, be divided into including Beidou epoch,
The height of GPS epoch, GLN epoch and antenna condition information broadcast frequency information, and refer to including CORS reference station coordinates, CORS
Station antenna information and the low of receiver description information broadcast frequency information；
Coding module, for broadcasting frequency information to height and low frequency information of broadcasting carries out anti-interference coding respectively；
High-power ultrashort wave radio set, the data after being encoded by ultrashort wave interface CORS service system are sent to long distance
From receiving end radio station, the transmission of data is completed；
Received data are decoded receiving end radio station by decoder module, and will send decoded CORS data
To background server, the transmission of CORS data is completed.
According to the above scheme, in the coding module, comprising:
Highly redundant anti-interference coding unit is carried out for broadcasting frequency information to height using highly redundant anti-interference coding mode
Coding；
Low redundancy anti-interference coding unit, for using low redundancy anti-interference coding mode to carry out low frequency information of broadcasting
Coding.
According to the above scheme, the highly redundant anti-interference coding unit is encoded using FEC (3/4) coding mode, low superfluous
Remaining anti-interference coding unit is encoded using FEC (7/8) coding mode.
The beneficial effect comprise that: this system is led to by using Beidou CORS vehicle and high-power ultrashort wave radio set
Cross CORS differential data and extract and encode the long range credible delivery for realizing CORS data, improve CORS data it is long away from
Anti- error code capacity from communication, improves communication quality, destroys especially suitable for communications service or feelings without communication signal
Condition.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing:
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to limit
The fixed present invention.
As shown in Figure 1, a kind of CORS data encoding Transmission system for being applicable in long haul communication, comprising:
Mobile Beidou CORS vehicle for receiving data by the Beidou receiver on vehicle, and is sent to CORS service system；
In communications service destruction or without communication signal region, after mobile Beidou CORS vehicle is fixed, using network interface or serial ports
Mode is by big-dipper satellite data access CORS service system.
CORS service system, for being grouped to the differential data information in CORS data, be divided into including Beidou epoch,
