Description
Technical field
One tests the speed quartz crystal weighing device immediately, relates to Dynamic Weighing Technology field.
Background technology
In recent years, China's road transport vehicle overload overloading is comparatively general, and has the gesture of " more and more fiery ".The roadbed of high capacity waggon to highway of overload has great destruction, has a strong impact on the serviceable life of highway, and overloaded vehicle is also one of major reason caused a traffic accident simultaneously.Vehicle overload overload transportation causes great harm to traffic safety order.The preliminary examination of current highway, high-grade highway, the weighing of weight metering charging and overrun testing, general employing weighing platform formula axle weight scale, although these weighing device dynamic weighing precision are not low, but some drivers adopt punching to jump scale, walk the malice violation running methods such as S shape, braking to alleviate measurement weight when weighing, these malice in violation of rules and regulations traveling behaviors, as can not be effectively detected, just there will be the phenomenon that the weight measured and actual weight are not inconsistent.
Utility model content
The technical problems to be solved in the utility model is: effectively cannot detect the situation that driver travels in violation of rules and regulations when weighing, thus there is the phenomenon that the weight measured and actual weight are not inconsistent, provide one immediately to test the speed quartz crystal weighing device for solving the problem.
The purpose of this utility model realizes in the following manner:
One tests the speed quartz crystal weighing device immediately, and it comprises the quartz crystal LOAD CELLS, signal amplifier, A/D converter and the embedded computer that connect successively, with micro-arrowband speed measuring device in described quartz crystal LOAD CELLS.
Described micro-arrowband speed measuring device is made up of two copper bars be embedded on quartz crystal sensor arranged along direction of traffic.In vehicular motion, wheel is successively pressed onto this two copper bar and produces electric charge, can the time interval T that produces of calculated charge, and the spacing between two copper bars is S, can draw the instantaneous velocity V of vehicle by this LOAD CELLS according to speed formula V=S/T.
Described micro-arrowband piezoelectricity speed measuring device is positioned at the edge of quartz crystal LOAD CELLS along direction of traffic.
In described quartz crystal LOAD CELLS with two micro-arrowband piezoelectricity speed measuring devices, lay respectively at the front-end and back-end of quartz crystal LOAD CELLS along direction of traffic.
Relative to prior art, the utility model increases micro-arrowband piezoelectricity speed measuring device in original LOAD CELLS, accurately can immediately measure the instantaneous velocity that on sensor, tire passes through, in conjunction with the weight data recorded, greatly can improve the heavy precision of meter, and there is the simple advantage of structure.
Accompanying drawing explanation
Fig. 1 is the quartz crystal sensor with micro-arrowband speed measuring device.
Fig. 2 is fundamental diagram of the present utility model.
Wherein, 1 is micro-arrowband piezoelectricity speed measuring device; 2 is quartz crystal LOAD CELLS; 3 is signal amplifiers; 4 is A/D converters; 5 is embedded computers.
Embodiment
As shown in Figure 1 and Figure 2, one tests the speed quartz crystal weighing device immediately, it comprises the quartz crystal LOAD CELLS 2, the signal amplifier 3 that connect successively, A/D converter 4 and embedded computer 5, with micro-arrowband piezoelectricity speed measuring device 1 in quartz crystal LOAD CELLS 2.Described micro-arrowband speed measuring device 1 is made up of two copper bars be embedded on quartz crystal sensor arranged along direction of traffic.In vehicular motion, wheel is successively pressed onto this two copper bar and produces electric charge, can the time interval T that produces of calculated charge, and the spacing between two copper bars is S, can draw the instantaneous velocity V of vehicle by this LOAD CELLS according to speed formula V=S/T; Described micro-arrowband piezoelectricity speed measuring device 1 is positioned at the edge of quartz crystal LOAD CELLS 2 along direction of traffic; In described quartz crystal LOAD CELLS 2 with two micro-arrowband piezoelectricity speed measuring devices 1, lay respectively at the front-end and back-end of quartz crystal LOAD CELLS 2 along direction of traffic.
principle of work of the present utility model is as follows: vehicle enters weight vehicle road, when vehicle is through quartz crystal LOAD CELLS 2, the electric charge of the generation of quartz crystal LOAD CELLS 2 amplifies through signal amplifier 3, simulating signal is converted to digital signal by A/D converter 4, be transferred to afterwards in embedded computer 5 and process, micro-arrowband speed measuring device 1 measures the instantaneous velocity of wheel through this sensor while weighing, can by judging whether the speed of a motor vehicle detects various abnormal running cheating mode extremely, and both combinations effectively can improve weighing precision.
Claims (4)
