Description
Technical field
The present invention relates to technology for deformation monitoring field, and in particular to a kind of deformation monitoring sensor for supporting remote control.
Background technology
Deformation monitoring is GNSS (Global Navigation Satellite System, GPS) high
One main application of precision positioning, the high accuracy positioning terminal of mm ranks is bridge, high tower, landslide and electric power tower
Monitoring and warning service is provided Deng facility, the problem of deformation monitoring sensor faces cost high, Maintenance Difficulty.
Deformation monitoring principle based on GNSS high accuracy positionings is that GNSS positioning antennas are fixed in monitoring object, and defeated
Go out original observed data and resolve platform to RTK (Real-Time Kinematic, in real time dynamically), RTK resolves platform combination ground
Strengthening system is completed RTK and resolved, and obtains the positional information of GNSS antenna, and positional precision is grade, the faint deformation of monitoring body
It can be monitored to, service platform monitors in real time, and issues warning data.Deformation monitoring principle based on GNSS high accuracy positionings
As shown in Figure 1.
In, deformation monitoring terminal is mainly made up of GNSS receiver and high-precision antenna, and antenna receives satellite-signal
GNSS receiver is linked into by RF cable, GNSS receiver processes to the satellite-signal of reception, and exports the original of monitoring
Begin observation data, and original observed data can pass through such as wireless bridge, 2G/3G/4G wireless data sendings DTU (Data Transfer
Unit, data transmission unit), optical fiber, the communication such as netting twine, transmit to National Data Processing Service.Data processing
The heart is a RTK post-processing algorithm platform, can complete the satellite fix of monitoring point antenna.The faint mobile meeting of monitoring point antenna
It is monitored to, monitoring accuracy can reach 2mm~5mm, monitors that aerial position changes and may be considered the object hair of monitoring
Displacement is given birth to.If installing multiple antennas in a monitoring object, the faint deformation that this monitoring object occurs can be also monitored out
Come.
RTK post-processing algorithms platform completes the work such as data processing, data analysis, data storage, report generation, will monitor
As a result real-time display, and Online release monitoring point real time data and warning information.
Integrated solution be typically use independent GNSS receiver, general GNSS receiver be internally integrated 1 piece it is high-precision
Degree positioning board, high accuracy positioning board have 2 independent signal processing channels, abbreviation double antenna high accuracy board, that is, support 2
Individual antenna access, the signal transacting of 2 monitoring points is completed, therefore a GNSS complete machine monitors the deformation monitoring of 2 points.
Communication can use broadband connections, and external harmoniousness needs to be equipped with router, interchanger and serial server；Also may be used
Possess 4G radio communications DTU with use to be communicated, each monitoring point of this mode is equipped with a DTU.
Original observed data is accessed RTK post-processing algorithms platform (service platform) by GNSS receiver, typically passes through Ntrip
Server (RTK reference stations) mode uploads data, and a kind of is that the high-precision board in GNSS receiver supports network interface, Ntrip
Server modes upload data；Another is that DTU integrates Ntrip server functions, and receiver output data is connect by serial ports
Enter DTU, DTU uploads data using Ntrip server modes.
The problem of prior art is present is embodied in design cost, installation and safeguards two aspects, specific as follows：
1st, in terms of design cost
By taking high tower deformation monitoring as an example, a building needs to install 4 GNSS positioning antennas in roof, will by RF cable
Radiofrequency signal introduces the GNSS receiver being arranged in building, and existing receiver at most only supports the access of 2 antennas, completes 2
The monitoring of individual monitoring point, it is therefore desirable to which two GNSS receivers complete the monitoring of 4 monitoring points.GNSS receiver positioning output is former
The observation data that begin are exported by serial ports or network interface.Under serial ports output mode, the data of 1 road 1 monitoring point of serial ports output, 4
There are 4 serial data outputs monitoring point, and these data are needed by network transmission to RTK post-processing algorithms platform, it is necessary to outside
Integrate 4 serial ports and turn the server of network interface, by the form of data Ethernet be output to can with the router of access band, or
Person is output to function of surfing the Net 4G wireless data transmission modules；If receiver exports observation data in the form of network interface, it is also desirable to
By network interface couple in router, or the Internet enabled 4G wireless data transmission modules of apparatus transmit data to access switch again.From system
In terms of complexity, cost, the system is all excessively cumbersome, it is necessary to be powered to each equipment, and data wire connection is complicated between equipment, separately
Outer to need that all equipment is installed with a rack or cabinet, infield and mounting means also bring along puzzlement.
2nd, installation and maintenance aspect：
DEFORMATION MONITORING SYSTEM principle is that the satellite data received using high accuracy positioning board to each monitoring point antenna is entered
Row processing, and observation data are exported, upload to RTK post-processing algorithms platform and carry out network RTK resolvings.Algorithm platform was being settled accounts
Need to adjust high-precision board relevant parameter according to the receipts star positioning states of test point once in a while in journey, improving stability reduces wrong report
Alert rate.Other GNSS receiver is typically assembled near test point, if high-precision board needs to carry out firmware upgrade, needs to tie up
Shield personnel are to ready-made carry out upgrade maintenance.Carrying out ready-made upgrading for monitoring point large number of, that area is remote needs to improve people
Power cost.In addition, there is account configuration each monitoring point, account corresponds to RTK post-processing algorithm platforms, and general RTK post processings are calculated
Method platform is the service platform of ground strengthening system operator, and each monitoring point uses independent counting mechanism, and 4 monitoring points need
4 accounts are configured, each account has corresponding password, provided by operator.So that high tower monitors as an example, 4, a building monitoring
Point, it is currently that directly high precision plates card is authorized, the sequence number that each good operator of board configured in advance provides, Ran Houcai
Can connectivity services platform.This scheme is unfavorable for managing, and the more GNSS receiver configurations in monitoring point can become complicated.
