A kind of ground sedimentation monitoring system based on CORS base station
Technical field:
The utility model relates to a kind of ground sedimentation monitoring system, is specially a kind of based on CORS base station ground sedimentation monitoring system
Background technology:
In recent years, land subsidence becomes a kind of geological phenomenon of general and increasingly significant.China has 96 cities and area generation land subsidence in various degree up to now, and this situation seems particularly outstanding in the city such as Tianjin, Shanghai.Land subsidence belongs to the geologic hazard of slow change type, generally not easily discovers, but irrecoverable again after being formed, and the ecologic environment to negative area, infrastructure etc. is produced serious influence.Therefore, set up Real-Time Monitoring net and obtain displacement accurately, Timeliness coverage settlement law, grasp sedimentation trend rather important.
Current Chinese most cities is carried out once every year to Ground Subsidence Monitoring, have accumulated a large amount of raw data, but data management means are delayed, and data analysis is inadequate, causes market demand level not high.And current Ground Subsidence Monitoring does not carry out Real-Time Monitoring, causing cannot the situation of early warning land subsidence timely and accurately.And continuous operational reference station (Continuously Operating Reference System, CORS) be one of the focus that modern GPS develops, networking concept is incorporated in geodetic applications by it, for Surveying and Mapping Industry brings deep change.Can Monitoring and forecasting system in real-time land subsidence, for urban planning layout and capital construction provide the decision-making foundation of science.
Utility model content:
The utility model is exactly for the problems referred to above, provides a kind of ground sedimentation monitoring system based on CORS base station.
To achieve these goals, the utility model adopts following technical scheme, comprises data acquisition submodule, Surveillance center's data processing submodule, communication submodule, big-dipper satellite.Described data processing submodule is connected with communication submodule, by multiple GPS measurement sensor, the displacement of monitoring station place land subsidence, described communication submodule respectively with big-dipper satellite, Surveillance center's data processing submodule, data acquisition submodule is connected, the land subsidence displacement data collected is transmitted, monitoring center's data processing submodule is connected with big-dipper satellite with communication submodule, to the data analysis process that data acquisition submodule gathers, described big-dipper satellite is connected with communication submodule with Surveillance center submodule, passing mutually in real time of Monitoring Data is realized by satellite-signal.
Described communication submodule comprises sts satellite transmission system, GPRS wireless transmission and wired optical cable.
The beneficial effects of the utility model:
The utility model is a kind of monitoring technology based on CORS base station, by the ingenious layout of multiple GPS measurement sensor, monitors ground floor displacement, achieves the Real-Time Monitoring to land subsidence.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Consult Fig. 1 known, the utility model comprises data acquisition submodule, Surveillance center's data processing submodule, communication submodule, big-dipper satellite.Described data processing submodule is connected with communication submodule, by multiple GPS measurement sensor, the displacement of monitoring station place land subsidence, described communication submodule respectively with big-dipper satellite, Surveillance center's data processing submodule, data acquisition submodule is connected, the land subsidence displacement data collected is transmitted, monitoring center's data processing submodule is connected with big-dipper satellite with communication submodule, to the data analysis process that data acquisition submodule gathers, described big-dipper satellite is connected with communication submodule with Surveillance center submodule, passing mutually in real time of Monitoring Data is realized by satellite-signal.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
