Description
Technical field
The utility model belongs to the vehicle detection technical field, is specifically related to a kind of dynamic electric automobile balance.
Background technology
Existing truck scale is from the product integrality, and great majority are not also broken away from the structures of static weighbridge, and that can realize dynamic weighing technically also exists many imperfection parts, still can not large-area applications.Present dynamic automobile scale mainly contains two kinds of forms: the one, and portable dynamic weighing system, the 2nd, fixed dynamic weighing system.The former is mainly used in administrative law enforcement, and manual intervention is more, can only weigh, and function singleness, the scope of application is narrower.The main application target of the latter is road monitoring, data acquisition maintenance, meterage etc., and function is also more single.The subject matter that these two kinds of products exist is that precision is not high, poor stability, the vehicle of weighing to pass through discrimination low.Simultaneously, these products use the shooting feature recognition technique to come the go-on-go vehicle more, the cost height, and system complex is unfavorable for safeguarding.
Summary of the invention
The purpose of this utility model is at the prior art above shortcomings, a kind of dynamic electric automobile balance is provided, on the scale body, be provided with and be used for branch car test survey and be used to detect the Function detection components and parts that the speed of a motor vehicle, wheelbase and tire quantity are used to detect the speed of a motor vehicle, wheelbase and tire quantity, improved the discrimination that passes through of vehicle, widened measuring ability, done improvement by the structure that is provided with simultaneously, improved the accuracy of detection and the degree of stability of truck scale greatly sensor.
The technical solution of the utility model is as follows:
This dynamic electric automobile balance is made up of scale body, data acquisition control device and Function detection components and parts, it is characterized in that: the Function detection components and parts comprise the infrared alignment tube that is used for the branch car test and surveys, the hall sensing device that is used to detect the speed of a motor vehicle, wheelbase and tire quantity, and their signal wire inserts data acquisition control device.Wherein, infrared alignment tube correspondence is installed on the monosymmetric column of scale body, by the situation of infrared transmission pipe and receiving tube transmission and receiving infrared-ray, judges whether vehicle passes through, and discrimination is high.The hall sensing device be installed in weighing platform below corresponding to vehicle by the time tire position of rolling, comprise the compensating squeeze head of being with magnetic patch and corresponding with magnetic patch that be provided with and be fixed in Hall element under the weighing platform, compensating squeeze head exposes the weighing platform surface, when automobile by the time roll compensating squeeze head, Hall element responds in succession, can obtain indexs such as the speed of a motor vehicle, wheelbase and tire quantity by calculating.
Further, the load sensor that is used for sense weight also is installed under weighing platform, the last pressure pad plate welding of the pressure head of load sensor and weighing platform is fixing, rather than prior art adopts the flexible connection form of bolt, by adjusting stop means, dwindle spacing, thereby improve the accuracy of detection and the degree of stability of truck scale greatly.
This dynamic electric automobile balance is owing to select the Function detection components and parts as required and setting rationally, utilize simple structure, the discrimination that vehicle when detecting is passed through reaches 100%, and has increased the detection of multiple indexs such as the speed of a motor vehicle, wheelbase and tire quantity, and measuring ability is expanded.In addition, change the syndeton of coincidence senser, improved the accuracy of detection and the degree of stability of truck scale greatly, improved the percent of pass of car.

Embodiment
Referring to Fig. 1 and Fig. 2, this dynamic electric automobile balance is made up of scale body, data acquisition control device 5 and several parts of Function detection components and parts.Function detection components and parts and scale body combine, and import signal into data acquisition control device by signal wire.The Function detection components and parts include three parts: the one, be used for the infrared alignment tube 4 that the branch car test is surveyed, the 2nd, be used to detect the hall sensing device 1 of the speed of a motor vehicle, wheelbase and tire quantity, the 3rd, be used for the load sensor of sense weight, their signal wire inserts data acquisition control device 5.
Referring to Fig. 1, infrared alignment tube 4 correspondences are installed on the weighing platform 2 monosymmetric columns 3 of scale body, and are when infrared transmission pipe sends infrared ray, middle unobstructed.When receiving tube receives infrared ray, can excite the numeration pulser of receiver, the numeration response.And have vehicle to pass through between pipe and the receiving tube when sending, and forming when stopping, receiving tube does not have the numeration pulse, does not respond, and can judge in view of the above whether vehicle passes through.By adjusting the spacing of infrared alignment tube, can reach 100% accurate judgement rate.
Referring to Fig. 1, hall sensing device 1 be installed in weighing platform 2 belows corresponding to vehicle by the time tire position of rolling.Referring to Fig. 2 and Fig. 3, it comprises the compensating squeeze head 8 of being with magnetic patch and corresponding with magnetic patch 6 that be provided with and be fixed in Hall element 7 under the weighing platform 2, compensating squeeze head 8 exposes weighing platform 2 surfaces, when automobile by the time roll compensating squeeze head 8, compensating squeeze head 8 drives the be directed downwards motion of magnetic patch 6 along power, excitation Hall element 7 produces response, after pressure disappears, compensating squeeze head 8 resets under the effect of spring, response disappears, we can judge that automobile has been pressed on the scale body in view of the above, when a plurality of hall sensing devices are arranged according to a certain percentage,, when pushing down 1-3 number generation response of hall sensing device, tire can judge that tyre width is the twice spacing referring to Fig. 4, when pushing down 1-3-5, can judge that tire wide is three times of spacings.Also can judge the speed of a motor vehicle simultaneously in view of the above, since the distance of No. 2 sensing devices and 1, No. 3 be fixing as can be known, when automobile rolls any one 1,3 sensing device, response is clocked and is just begun, and when the 2nd and No. 4 sensing device do not stress, clocks continuously, when 2, No. 4 pressurizeds, response is clocked and is stopped, and obtains automobile by the required time S of fixed range L, by formula V=L/S as can be known automobile by the speed of weighing platform.
The position of load sensor 9 is referring to Fig. 3, what have change a bit is that the pressure head 11 of load sensor and the last pressure pad plate 10 of weighing platform are that welding is fixing, rather than prior art adopts the flexible connection form of bolt, by adjusting stop means, dwindle spacingly, come impact, distortion with this to load sensor, reduce the jitter time of scale body when detecting, thereby improve the accuracy of detection and the degree of stability of truck scale greatly.12 is to press down backing plate among the figure.
Data acquisition control block diagram of the present utility model is referring to Fig. 5, hall sensing device and infrared alignment tube pass the signal along to data acquisition control device by terminal box respectively, after handling as calculated, show or printout by display device (as display screen, display etc.).And the signal of load sensor is received the display instrument of weighing after by the electronics terminal box, passes to data acquisition control device again, after also handling as calculated, shows or printout by display device (as display screen, display etc.).
