Description
Technical field
The utility model relates to a kind of bridge safety supervision technology, relates in particular to a kind of bridge displacement and expansion joint width telemetry system based on Internet of Things and laser.
Background technology
Expansion joint width displacement between beam body on bridge and the relative shift of bridge pier and beam body is the key parameter in bridge health monitoring, so far, in prior art, also there is no directly to measure the instrument of aforementioned two kinds of displacements, the general mode of artificial regular detection that all adopts is measured, the reliability of manual detection and dirigibility are all poor, not only measuring cost high, and cannot realize real-time measurement, there is certain security risk in work high above the ground simultaneously.
Utility model content
For the problem in background technology, the utility model proposes a kind of bridge displacement and expansion joint width telemetry system based on Internet of Things and laser, comprise the multistage beam body being laid on bridge pier, between adjacent two sections of beam body end faces, be provided with expansion joint, its innovation is: on bridge pier, be provided with fixed mount, fixed mount is positioned at the outside of expansion joint span scope inner beam body, is provided with two groups of laser ranging systems on fixed mount; Adjacent two sections of beams are respectively provided with a laser reflection target with it, and two groups of laser ranging systems can be measured the distance between the laser reflection target of both sides and fixed mount respectively.Therefore it will be apparent to those skilled in the art that the problem that has short distance blind area in laser ranging, when laser reflection target is set, should make spacing between laser reflection target and laser ranging system be greater than the length of short distance blind area.
The principle of aforementioned schemes is: after by scheme of the present utility model, laser ranging system and laser reflection target being in place, adopt laser ranging technique to measure for the first time the distance of fixed mount and laser reflection target, thereby obtain raw data, in follow-up observation process, by laser ranging system, obtain the current distance data of fixed mount and laser reflection target, difference by current distance data and raw data just can calculate the displacement between fixed mount and laser reflection target, because fixed mount and laser reflection target are arranged at respectively with it bridge pier and beam, therefore the displacement essence between fixed mount and laser reflection target is just above equal to the displacement between bridge pier and beam body, this has just realized the detection to bridge pier and beam body displacement, when we get after these two displacement datas of displacement between the laser reflection target of fixed mount and its both sides, original width in conjunction with known expansion joint, by simple calculating, we just can obtain the wide variety amount at expansion joint.
Laser ranging technique is existing routine techniques, the utility model for the contribution of prior art be not embodied in measuring technique originally with it, as said in background technology, in prior art when measuring between bridge pier and beam body displacement and adjacent beams body this two kinds of parameters of displacement, need artificial climbing to on-the-spot, carry out in-site measurement, not only there is potential safety hazard in this, but also exist measurement cost large, the problem that measuring result error is large, and adopt after scheme of the present utility model, technician only need work by Long-distance Control driving laser distance measuring equipment, just can get corresponding measurement result, measuring process is efficient and convenient, and measurement result is comparatively accurate, guaranteed the real-time of bridge safety supervision desired data, for bridge safety supervision provides a kind of new means.
Based on aforementioned schemes, preferably, described laser ranging system is comprised of a generating laser and a detector, and the generating laser of same laser ranging system and detector are arranged at the homonymy of fixed mount; Its principle is: the laser beam that generating laser sends is detected device after being reflected by laser reflection target and captures, and according to the difference between launch time and time of reception, just can calculate the distance between generating laser and laser reflection target.
Depend on the communication technology of existing maturation, the utility model also can be done following improvement: on described fixed mount, be also provided with communication module, the signal that communication module collects detector is converted to after wireless signal to outer transmission.The data processing terminal that the destination sending is rear end, technician can complete the analysis aftertreatment to Monitoring Data by service data processing terminal in the wings.
The line of promising illuminator supply electric power is generally all set on bridge, device of the present utility model can share line with illuminator, also can set up separately supply line, in addition, in order to save the energy, also the utility model can be combined with ripe solar powered technology, with the self energizing of implement device, concrete scheme is: described laser ranging system adopts solar panel energy supply, and solar panel is arranged on the body of a bridge.
Useful technique effect of the present utility model is: for the measurement of beam body displacement and expansion joint displacement provides a kind of brand-new means, can get real-time and efficiently measurement of correlation data, measuring process is more convenient than prior art, cost is lower, measurement result is also more accurate.
