Embodiment:
Near highway tollgate, follow the car direction with reference to Fig. 1 and set gradually telefault (1), sensor for tyre recognizing (2), weighing platform (3,4), telefault (6), a pair of infrared light curtain separation vessel (7,8) is set in coil (6) symmetria bilateralis.
Inductive coil (1,6) constitutes an oscillator with coil controller (12), when the vehicle approaching, oscillator frequency signal changes, and coil controller (12) sends an automobile storage at signal, when vehicle left, coil controller (12) sent a vehicle and leaves signal.The model that coil controller (12) adopts is PD132.Coil (1,6) adopts copper conductor to make, and is of a size of 1000mm * 500mm, 4 circles, imbeds underground about 50mm place.
Sensor for tyre recognizing (2) adopts piezoelectric element and special-purpose encapsulant and insulation polyurethane to dress up the strip that length is 1600mm or 1900mm, and this device adopts two, and model is DN106.
Weighing platform mechanism is composed in series by the center line that weighing platform (3,4) follows the car direction, separate on mechanics between the weighing platform (3,4), the work top of weighing platform (3,4) is in same plane, assembly clearance between the weighing platform (3,4) should be as far as possible little, the most very much not should surpass 20mm, weighing platform (3,4) should be provided with position-limit mechanism separately, prevents mutual collision.Weighing platform (3,4) agent structure is welded into cellular structure by the thick steel plate of 350mm i shaped steel, U-steel and 16mm, assurance has enough intensity and rigidity, four jiaos of weighing platform (3,4) bottom surface are provided with LOAD CELLS, supporting weighing platform (3,4), the size of two table tops of weighing platform (3,4) can be made into two kinds of 3600mm * 800mm and 4000mm * 800mm.Each weighing platform adopts four LOAD CELLS, and can adopt model is 10 tons of beam type resistance strain sensors of YZC-3SH.
Infrared light curtain separation vessel (7,8) is symmetricly set on telefault (6) both sides, and as the judgement signal whether vehicle passes through, can adopt model is the infrared light curtain separation vessel of MINI-ARRAY to infrared light by shield when vehicle passes through.
Data acquisition unit (10) is responsible for the collection to weight signal, coil-induced information, tire identifying information, infrared resolution information, every LOAD CELLS is sampled respectively, A/D converter can adopt 24 ∑s-Δ A/D converter of CIRRUS LOGIC company, after carrying out pre-service such as scale conversion, information of vehicles is sent to industrial control computer, and can adopt model is DN108.Data output interface is RS-422.
Industrial control computer is the core of this utility model, with program Solidification in solid-state disk and do not have hard disk.The weight data of input, the identification of coil-induced, tire, infrared resolution information are handled, obtained axle weight, gross weight, the information such as transfinite of vehicle and send charging administration system to.Can adopt model is NuPRO-776, CPU Intel Petium III 850MHZ; Support electric board DOM2000; Internal memory 256MB; Super I/O; Two 16C550UART, compatible RS-232.
When vehicle drive into the road vehicle weight metering charging, when transfiniting device for dynamically detecting, the first step: by coil (1), the oscillator that coil (1) and coil controller (12) constitute produces frequency change, send after treatment automobile storage signal.Second step: vehicle is sent signal into tire recognizer (11) after by sensor for tyre recognizing (2), discerns the tire number of each axletree.The 3rd step: vehicle is successively by weighing platform (3,4), near four angles of weighing platform (3,4), respectively be provided with a range and be 10 tons beam type resistance strain sensor, change weight signal into electric signal and send data acquisition unit (10) to, collector (10) carries out A/D conversion respectively to 12 road signals, carries out changing information over to industrial control computer (5) after the pre-service such as scale transformation.Owing to adopted weighing platform mechanism relatively independent on two mechanics, that on direction of traffic, closely link to each other, when vehicle passes through, both avoided a same phenomenon that table top interferes with each other of vehicle two axles, simultaneously, the effectively time of weighing of two table tops is multiplied, by computing machine the information of twice measurement is synthesized processing, see accompanying drawing 3.The A curve is the weight/time curve of an axletree by weighing platform (3) in the accompanying drawing 3, and the B curve is the weight/time curve of same axletree by weighing platform (4), and C curve is weight/time curve and the resultant curve that an axletree passes through weighing platform (3,4) successively.Because the information acquisition amount is much larger than single weighing platform mechanism, measuring error only be 1/4 of a single weighing platform mechanism, in addition, and the reliability of the equipment redundancy raising system of the multisensor by two weighing platforms (3,4) mechanism.The 4th step: after vehicle was simultaneously by coil (6) and infrared light curtain separation vessel (7,8), it is normal that the oscillator frequency that coil (1) and coil controller (12) constitute is recovered, and controller (12) sends vehicle to system and leaves signal, finishes this car test and survey.Detection system can start the testing process to next car automatically.When detecting the end computer-chronograph weight is judged (whether overweight), form the partial data of one-time detection.Computer software is the core of this device, process flow diagram is seen accompanying drawing 2, computing machine (13) receives rapidly accurately information and the data from LOAD CELLS, tire recognizer (2), infrared light curtain separation vessel (7,8), infrared light curtain controller (9), coil controller (12) and data acquisition unit (10), obtains the information such as axle weight, gross weight, vehicle, a type, the rate that transfinites, speed, acceleration of vehicle after machine (13) is handled as calculated.
