Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with drawings and Examples pair The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the present invention, not For limiting the present invention.
In order to meet the demand in different application field, deformation monitoring precision need to be in grade even submillimeter level.With The progress of GNSS satellite location technology and the lifting of receiver hardware performance, and all kinds of auxiliary enhanced navigation systems development, Precision needed for deformation monitoring can be met using GNSS satellite location technology completely, obtained widely should in deformation monitoring field With.
On the other hand, in technical field of navigation and positioning, based on multi-source fusion positioning thought realize High Availabitity, it is highly reliable, High-precision navigator fix is one of current GNSS navigator fixs prior development direction all the time, especially realizes the seamless rank of indoor and outdoor Sub-meter grade, the Centimeter Level navigator fix for connecing, with prominent meaning.
To sum up, the present invention proposes a kind of navigator fix based on symbiosis concept and deformation monitoring method and system, by work The deformation monitoring operation of industry and civil buildings is merged with High Availabitity, highly reliable, high accuracy positioning navigation feature in the way of symbiosis It is integrated, meaning and quite varied application prospect is realized with very important.
In symbiosis navigator fix and DEFORMATION MONITORING SYSTEM based on frequency modulation data radio as shown in Figure 1, according to the present invention Symbiosis navigator fix and deformation monitoring method, be related to GNSS satellite, deformation monitoring terminal, cell deformation monitoring center, yardage According to administrative center, five parts of user's navigation neceiver.So that certain residential area carries out deformation monitoring to building in the cell as an example, For a certain building, it is necessary to install two or more deformation monitoring terminal, each deformation monitoring end in ad-hoc locations such as roof corners End receives the navigator fix signal of GNSS satellite, to itself carrying out high-precision positioning time service, and by self poisoning time service result User's navigation positioning receiver on cell deformation monitoring center and periphery is distributed to using data frequency modulation broadcasting mode message；Cell Deformation monitoring center is monitored analysis to the precision positions data of the building each deformation monitoring terminal in real time, judges that each is built Build the hidden danger for whether having and deforming and cave in；Code control data corporation manages the pseudo-code information of all deformation monitoring terminals, when with When family navigation neceiver sends yard range of requests, user's navigation neceiver region possible pseudo-code of deformation monitoring terminal is informed Scope, user's navigation neceiver receives surrounding deformation monitoring terminal signaling accordingly, and being considered as pseudo satellite, pseudolite with the thought of function symbiosis believes Number, with reference to GNSS satellite navigator fix signal, complete to be accurately positioned the work such as navigation or indoor positioning to itself.
The code control data corporation, centrally disposed with deformation monitoring can be integrated, and can also be provided separately, according to specific Application scenarios and actual demand flexibly set.
Fig. 2 is the pseudo-code modulation symbiosis navigator fix and the schematic flow sheet of deformation monitoring method of one embodiment, such as Fig. 2 Shown pseudo-code modulation symbiosis navigator fix and deformation monitoring method, including：
Step S10, receives satellite message signal.
Specifically, deformation monitoring terminal is responsible for receiving the telegraph signal of each satellite.
Step S20, according to the satellite message signal acquisition deformation monitoring terminal positioning time service information, the deformation monitoring Terminal positioning time service information includes：Deformation monitoring terminal self-position and deformation monitoring terminal time service information.
Specifically, according to the satellite message signal, obtaining the own location information and time service information of deformation monitoring terminal. Wherein, satellite message signal is parsed, positioning is carried out and time service information is obtained, obtained using traditional satellite fix and time service information Take method.
Step S30, the deformation monitoring terminal positioning time service information is modulated using pseudo-code, obtains pseudo-code modulation intelligence, institute The code length for stating pseudo-code is 2 integral number power, is repeated by the cycle of 2 integral number power, and is stochastic ordering within a repetition period Row.
Specifically, the C/A yards of golden code using 1023 length of traditional gps satellite signal, co-exists in 1025 different sequences, Although distributing to whole gps satellites enough to use, residential building accumulation regions in view of building substantial amounts in limited range or High-tech industrial park, and the deformation monitoring terminal quantity for increasing at any time as needed is, it is necessary to a kind of generate in convenient, number of codes Limit pseudo-code of the sufficiently large pseudo random sequence code as deformation monitoring terminal-specific.Therefore, the present embodiment provides a kind of new puppet Code, feature is as follows：
1) different from C/A yards of tradition, the pseudo-code code length is 2n, i.e., 2 integral number power.
