Description of drawings
Accompanying drawing is wireless monitor system structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, consult accompanying drawing, system mainly is comprised of modules such as static sensor, data processor, data transmit-receive unit, database acquisition management centers.Static sensor is mainly the geotechnical engineering detecting sensor, can be connected with data acquisition controller separately.The data processor major function is the pick-up transducers data and is transferred to data acquisition controller with digitized forms.The data transmit-receive unit is wireless or wired both-way communication module, collects the monitored data that is collected by data acquisition controller, sends to database acquisition management center module.
Adopt wireless monitor system, the holding wire of sensor is connected to same bus under vacuum diaphragm, and bus passes transmitted signal from disposal field peripheral sealing wall under vacuum diaphragm.With respect to the traditional monitoring method, this method can be avoided the destruction to vacuum diaphragm, has reached the requirement that guarantees vacuum under the film.
The field monitoring terminal structure forms and is comprised of acquisition terminal, portable terminal and holding wire.Wherein, acquisition terminal comprises various sensors and acquisition module, on-the-spot each the measuring point delaminating deposition of foundation soil of realization is adopted collection and the interim storage of transmission of data, wherein the modules function is as follows: sensor is responsible for various physical signallings are converted to the signal of telecommunication, then carries out data by acquisition module and processes; The signal that the acquisition module receiving sensor is sent carries out data acquisition and interim storage, sends to monitoring center then through serial ports and communication of mobile terminal, and then with data; Portable terminal is responsible for carrying out signaling and exchanges data with existing GSM base station as on-site terminal and monitoring center's data communication entity, is responsible for being linked in the wireless network, and then realizes the real time data exchange with monitoring center.
