Description

A kind of Bridge Condition Monitoring system based on the GSM note

Technical field

The utility model relates to the field of bridge monitoring, especially a kind of Bridge Condition Monitoring system based on the GSM note.

Background technology

Along with the demand of progress and the communications and transportation of science and technology, Bridge Health Monitoring Technology progressively becomes the important channel of the rule research of large bridge structure Law of Disastor Evolution and safety guarantee in real time.Large bridge has the characteristics such as king-post is high, span is large, and the main contents of its deformation monitoring comprise: Bridge Pier settlement observation, Pavement linear and deflection observation, the observation of girder transverse horizontal displacement etc.For carrying out the measurement of above-mentioned projects, must set up the observation of corresponding horizontal shift reference net and sedimentation reference net.

Need uninterrupted monitoring in 24 hours for more above-mentioned data at present, possess very high real-time, its early warning also has same performance requirement, and the bridge management person is often not on-the-spot at bridge, can't in time obtain early warning information, enter monitoring center and check the early warning situation; Early warning system provides by Internet carries out remote-control and early warning interface, but the remote area of a lot of bridge does not often have the Internet network connection, can't realize remote-control and early warning.

Summary of the invention

The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of Bridge Condition Monitoring system based on the GSM note, and information that can the Real-Time Monitoring bridge, thus can in time understand fast and accurately early warning information.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of Bridge Condition Monitoring system based on the GSM note, comprise at least three strain gauges that are distributed on the bridge, be located at the displacement transducer of seam crossing on the bridge, A/D change-over circuit module, the CPU processor module, GPRS wireless transmission signaling module, GPRS wireless receiving signaling module, control center's server, gsm communication module and short message warning information, described strain gauge is connected with the CPU processor module by A/D change-over circuit module respectively with displacement transducer, the CPU processor module is connected with GPRS wireless receiving signaling module by GPRS wireless transmission signaling module, GPRS wireless receiving signaling module is transferred to control center's server with the signal that receives, and control center's server sends out short message warning information by the GSM communication module.

Described a kind of Bridge Condition Monitoring system based on the GSM note also comprises and is distributed in the lip-deep temperature sensor of bridge, and temperature sensor is connected with the CPU processor module by A/D change-over circuit module.

The beneficial effects of the utility model are: described a kind of Bridge Condition Monitoring system based on the GSM note, adopt the monitoring system of this kind design, can monitor all sidedly the health status of bridge, by the gsm communication module mode of early warning information with note is sent on managerial personnel's the mobile phone simultaneously, makes the bridge management personnel learn timely and accurately early warning information.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the one-piece construction block diagram of a kind of Bridge Condition Monitoring system based on the GSM note described in the utility model.

Accompanying drawing acceptance of the bid score state as follows: 1, strain gauge, 2, displacement transducer, 3, A/D change-over circuit module, 4, CPU processor module, 5, GPRS wireless transmission signaling module, 6, GPRS wireless receiving signaling module, 7, control center's server, 8, gsm communication module, 9, short message warning information, 10, temperature sensor.

Embodiment

By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

A kind of Bridge Condition Monitoring system based on the GSM note as shown in Figure 1, comprise at least three strain gauges 1 that are distributed on the bridge and be located at the displacement transducer 2 of seam crossing on the bridge and be distributed in the lip-deep temperature sensor 10 of bridge, strain gauge 1 is connected with CPU processor module 4 by A/D change-over circuit module 3 respectively with displacement transducer 2 and temperature sensor 10, CPU processor module 4 is connected with GPRS wireless receiving signaling module 6 by GPRS wireless transmission signaling module 5, GPRS wireless receiving signaling module 6 is transferred to control center's server 7 with the signal that receives, and control center's server 7 sends out short message warning information 9 by GSM communication module 8.

A kind of Bridge Condition Monitoring system based on the GSM note of the present utility model, when using this monitoring system, utilize strain gauge 1 to come measuring vehicle through the STRESS VARIATION behind the bridge section, utilize displacement transducer 2 to come measuring vehicle through the variation of displacement behind the bridge section, utilize temperature sensor 10 to come measuring vehicle through the variation of temperature behind the bridge section, three signals are transferred to A/D change-over circuit module 3, A/D change-over circuit module 3 becomes analog signal conversion to export to CPU processor module 4 after the digital signal and extract characteristic, then utilize GPRS wireless transmission signaling module 5 to send data, by GPRS wireless receiving signaling module 6 receive datas, the data that receive are imported control center's server 7 into, send out short message warning information 9 to monitoring personnel's mobile phone by GSM communication module 8 at last.

Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
