Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is system monitoring deflection of bridge span schematic diagram described in the utility model;
Fig. 2 is measurement of dip angle principle schematic;
Fig. 3 is automatic running on transmisson line platform automatic running on transmisson line schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
A kind of deflection of bridge span automatic monitoring system based on smart mobile phone that the utility model provides, this system comprises automatic running on transmisson line platform, smart mobile phone; Described smart mobile phone is fixed on automatic running on transmisson line platform; Described automatic running on transmisson line platform is for carrying smart mobile phone and at the uniform velocity advancing according to the graticule automatic running on transmisson line of bridge pavement; Containing multi-shaft acceleration transducer in described smart mobile phone, for image data, and then calculate the inclination value of current smart mobile phone position; Also containing bridge deflection monitoring module in described smart mobile phone, for draw linear through region.
Automatic running on transmisson line platform comprises road wheel, power supply, drive unit, central processing unit, route identification module; Described power supply is connected with central processing unit respectively with drive unit, and drive unit is connected with road wheel by gearing; Described central processing unit is connected with route identification module; Described route identification module for gathering information of road surface and transferring to central processing unit, and then judges the position of automatic running on transmisson line platform, ensures that automatic running on transmisson line platform travels according to roadmarking all the time.
Mobile phone z-axis is by the effect of 1g acceleration of gravity, and when after mobile phone run-off the straight, sensor z-axis component can follow angle change, therefore can by calculating the weight component of z-axis, and calculate the size at inclination angle, principle as shown in Figure 2.
Cos θ=G
survey/ 1G;
Wherein, G
surveyfor measurement value sensor, 1G is terrestrial gravitation acceleration 9.8N/kg; θ is inclination angle.
Can in the hope of the inclination value of current phone position by trigonometric function formula, automatic running on transmisson line platform is used to carry smart mobile phone, automatic running on transmisson line platform at the uniform velocity advances according to the graticule automatic running on transmisson line of bridge pavement, the change at smart mobile phone real time record inclination angle simultaneously, after automatic running on transmisson line platform cruises complete bridge floor, mobile phone can draw out the linear of bridge by the inclination value measured, comparatively or with the bridge linear after having constructed contrasted by the linear ratio detected with last issue, the amount of deflection change curve of bridge can be obtained.
