Virtual displacement monitor is mounted on monitored building, and the GNSS for transferring data to monitoring station in real time is received On machine, big-dipper satellite receives the signal in the GNSS receiver of monitoring station and reference station simultaneously, in the GNSS receiver of reference station Reference of the data as virtual coordinates data received in the GNSS receiver of monitoring station.
In a preferred embodiment: the client is transmitted by being connected to the network multiple mobile terminals, and to mobile terminal Data analysis result and alarm signal.
In a preferred embodiment: the GNSS receiver uses high-frequency multi-mode GNSS receiver.
In a preferred embodiment: the virtual displacement monitor is to have the function of real-time recorded data and remote transmission number According to the recorder of function.
In a preferred embodiment: the GNSS receiver of the multiple reference station forms reference net, and provides mutually reference Multiple reference datas.
In a preferred embodiment: lightning protection device is provided at the GNSS receiver, the lightning protection device is using coaxial Cable arrester.
Compared to the prior art, the utility model has the beneficial effects that:
The utility model can will be counted by the way that multiple virtual displacement monitors are arranged in the easily-deformable region of high-rise According to the GNSS receiver for being transmitted to monitoring station immediately, i.e. the obtained data of the GNSS receiver of monitoring station, which are that building is practical, to be surveyed Magnitude avoids the measured place that the GNSS receiver of monitoring station is placed directly in building, there is very big installation inconvenience and easily In the risk of damage, reference station is set at firm basic point, using GNSS receiver and Beidou satellite communication, obtains monitoring in real time Data are resolved and are divided by control centre by the carrier phase data and net adjusted data data of point and reference point GNSS receiver Analysis resolves mode using double difference, handles carrier phase difference data, obtain deformation quantity of the monitoring point relative to datum mark, that is, obtain Real-time building displacement, and figure and report, alarm signal are sent on the mobile terminal of monitoring personnel by client, To handle crisis in time.
In short, high-rise system for monitoring displacement provided by the utility model, is based on big-dipper satellite location technology, passes through GNSS receiver, in the lasting observation of fire bottom offset, avoids security crisis to high-rise.
Detailed description of the invention
Fig. 1 is that the structure that building displacement monitors system under the fire based on big-dipper satellite during the utility model is preferably implemented connects Connect schematic diagram;
Fig. 2 is monitoring platform composition figure during the utility model is preferably implemented.
Specific embodiment
It elaborates with reference to the accompanying drawing to specific embodiment of the utility model.
As shown in Figure 1, a kind of high-rise system for monitoring displacement, including control centre 1, multiple monitoring stations 2 and multiple Reference station 3, the monitoring station 2 and the reference station 3 are all set at firm basic point, and consolidating basic point may be selected firm basement rock, GNSS receiver 4 is provided at monitoring station 2 and reference station 3, GNSS receiver 4 passes through network connection control centre 1, control Center 1 includes client 5, database 6 and solving unit 7, and the client 5 shows and alarms for data analysis, icon, institute Solving unit 7 is stated for receiving the data of the transmission of GNSS receiver 4 and carrying out data conversion, the database 6 is for storing solution Calculate the data after unit 7 resolves and the data source as the analysis of 5 data of client.
Virtual displacement monitor 9 is mounted on monitored building, and the GNSS for transferring data to monitoring station 2 in real time connects On receipts machine, big-dipper satellite receives the signal in the GNSS receiver 4 of monitoring station and reference station simultaneously, and the GNSS of reference station 3 is received Reference of the data as received virtual coordinates data in the GNSS receiver 4 of monitoring station 2 on machine 4.
The specific operation process of virtual displacement monitor 9 is: being fixed on building in the installation of virtual displacement monitor 9 Afterwards, an initial displacement coordinate data is given, GNSS receiver 4 of corresponding 2 the inside of monitoring station is correspondingly connected with its, when virtual When the displacement data coordinate of displacement monitors 9 changes, the data of 4 the inside of GNSS receiver also accordingly change, and then meet GNSS The data of receipts machine 4 are converted into the data of big-dipper satellite acceptable signal, then the received data of big-dipper satellite are to be mounted on building The data of actual coordinate displacement on object, are displaced with this to monitor when achieving the effect that real-time.
Client 5 can transmit data analysis result and report by being connected to the network multiple mobile terminals 8, and to mobile terminal 8 Alert signal.The user of mobile terminal 8 is safety responsibility people, construction responsible person or a people or more people in expert observer, is being occurred Alarm signal can be obtained when deformation, in time to start corresponding treatment measures and prediction scheme.
The data that GNSS receiver 4 transmits include carrier phase data and net adjusted data etc., and solving unit 7 is according to every GNSS The corresponding IP address of receiver 4 and port numbers distinguish point number, and real-time resolving goes out the three-dimensional coordinate of each monitoring point 2 and stores to number According in library 6, client 5 show that it is displaced accordingly and shows corresponding figure by analyzing 6 data of database And report issues alarm signal when building displacement acceleration occurs abnormal in time, and relevant departments is reminded to start as early as possible accordingly Treatment measures and prediction scheme, the generation of disaster is avoided, or transfer finance, the evacuation masses in time, caused by reducing after disaster occurs Loss.
There are metal-back and insulator protection in the outside of virtual displacement monitor 9, adapts to various atrocious weathers with this, empty The mounting means of quasi- displacement monitors 9, which can be, to be anchored with building, welds, between the GNSS receiver of monitoring station Data transmission can be through network transmission, be also possible to be transmitted between bluetooth.
Database 6 in the utility model be not one simply merged as various data made of very large database, but A kind of structural data environment for aiming at on-line analysis and applying with information system offer data source and decision tool.It is by data Source, storehouse management, data warehouse and analysis four part of exploitation tool composition.
Building displacement monitoring method under the above-mentioned fire based on big-dipper satellite: include the following steps:
1) it analyzes and determines the easily-deformable region of building structure, then pass through welding or the method anchored for virtual displacement Monitor 9 is mounted on its position, and an initial displacement coordinate value is arranged, and the GNSS receiver 4 with its corresponding monitoring station 2 is right It should connect, when the displacement data coordinate of virtual displacement monitor 9 changes, the data of 4 the inside of GNSS receiver of monitoring station 2 It is corresponding to change, then convert the data of the GNSS receiver 4 of monitoring station to the data of big-dipper satellite acceptable signal;
2) it is resolved and is divided by data of the control centre 1 to monitoring station 2 and reference station 3 that big-dipper satellite receives Analysis resolves mode using double difference, handles carrier phase difference data, obtain deformation quantity of the monitoring point relative to datum mark, that is, obtain Real-time building displacement, and figure and report, alarm signal are sent on the mobile terminal of monitoring personnel by client.
The above is only the preferred embodiments of the utility model, but the scope of the utility model is without being limited thereto, the skill of this field Art personnel are easily envisaged that variation disclosed in the utility model or technical scope.Alternative solution is intended to cover practical at this In novel range.Therefore, the protection scope of the utility model should be determined by the scope of the claims.
