Abstract
The invention discloses a kind of station CORS data acquisition analysis methods, can effectively can control in real time the collection point quality of data when making an on-the-spot survey test early period when magnanimity builds the station CORS process, judge whether to meet construction website.Processing analysis is carried out to data through system, under the visualization of database operation platform, returned data is monitored in real time, controls collected data.If illustrating that the site is difficult to meet CORS construction requirements specification if it find that the collected quality of data is not good enough in collection process, replacing site in time, expeditiously data acquisition and judgement, save the cost.
Description
Technical field
The present invention relates to CORS station data collecting field more particularly to a kind of station CORS data acquisition analysis methods.
Background technique
Existing CORS data acquisition in process of building a station is mainly GNSS receiver storage initial data, by > 24
Hour data acquisition after, the problem of recycling receiver downloading data is analyzed, and existing analysis method is primarily present, is:
(1) it can not accomplish that dynamic is controlled in real time to collection process, occur in receiver data acquisition powering off or failure, then stop
Acquisition, real time status can not know；(2) quality of data collected needs post analysis process, can not scene grasp on-the-spot test
The quality of environment；(3) data tested are only GNSS receiver individual event storage, if receiver card card failure or data storage
It goes wrong, early period, test was fallen short of success for lack of final effort.
Summary of the invention
In view of the above technical problems, the purpose of the present invention is to provide a kind of station CORS data acquisition analysis methods.This hair
The bright data acquisition efficiency problem for being able to solve CORS and building a station during addressing, and the real-time control to data acquisition, this hair
In industry portion has exclusive property, high efficiency and applicability to bright analysis method.
To achieve the above object, the present invention is realized according to following technical scheme:
A kind of station CORS data acquisition analysis method, which comprises the steps of:
Step S1: first judgement test ambient conditions before test just sentences the continuation step that site environment meets test condition
S2 does not meet the continuation step S1 of test environment；
Step S2: simulation website is open-minded in test process, after test data is sent back by 4G wireless routing or DTU
Data are handled and are backed up by background data base system by platform Database Systems, and data are shown back to operation circle
Face visualization；
Step S3: frequency, the carrier wave phase of each satellite real-time reception are observed in viewing database operation platform visualization in scene
Position, pseudorange, cycle slip and multipath index are previously obtained each index parameter built a station, tentatively judge the quality of data, surveyed
Test result；
Step S4: if the data of field observation discovery back to database operation platform, which have, lacks frequency caused by frequency interferences
Situation, multipath index are high, replace test station in time, avoid the waste of testing time resource.
In above-mentioned technical proposal, whether step S1 is that nearby have high-lager building or large area high by test point position
Angle blocks and tests whether terrace has iron sheet roof or the site environment of the smooth reverse side of solar water heater tentatively to sentence
The superiority and inferiority degree of disconnected test data quality.
Compared with prior art, the present invention having the following beneficial effects:
Analysis method of the invention has real-time, controllability and high efficiency in test process, and data back visualization refers to
Mark display can have scene judgement and build a station the function of feasibility；
In addition, the present invention also has the reliability of test, return data storage backup is so that test process is more secure.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is the principle of the present invention schematic diagram.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.
Fig. 1 is the principle of the present invention schematic diagram, the data acquisition analysis method as shown in Figure 1, a kind of CORS of the invention stands,
Include the following steps:
Step S1: first judgement test ambient conditions before test just sentences the continuation step that site environment meets test condition
S2 does not meet the continuation step S1 of test environment；
Wherein, nearby whether there is blocking and testing for high-lager building or large area high angle by test point position
Whether terrace has iron sheet roof or the site environment of the smooth reverse side of solar water heater tentatively to judge the excellent of test data quality
Bad degree.
Step S2: simulation website is open-minded in test process, after test data is sent back by 4G wireless routing or DTU
Data are handled and are backed up by background data base system by platform Database Systems, and data are shown back to operation circle
Face visualization；Also RTCM data can be sent while GNSS receiver stores initial data in this way back to background server, led to
It crosses background server and data is subjected to back-up processing；Avoiding the occurrence of the receiver failure because of collection in worksite data or having a power failure causes
Data are not complete.
Step S3: frequency, the carrier wave phase of each satellite real-time reception are observed in viewing database operation platform visualization in scene
Position, pseudorange, cycle slip and multipath index are previously obtained each index parameter built a station, tentatively judge the quality of data, surveyed
Test result；
Wherein, index of building a station of the invention: efficient >=95；Multipath MP1≤0.5, MP2≤0.6；Cycle slip ratio O-slp
≥8000。
Step S4: if the data of field observation discovery back to database operation platform, which have, lacks frequency caused by frequency interferences
Situation, multipath index are high, replace test station in time, avoid the waste of testing time resource.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make a variety of changes or modify within the scope of the claims, this not shadow
Ring substantive content of the invention.In the absence of conflict, the feature in embodiments herein and embodiment can any phase
Mutually combination.
