As shown in fig. 1-2, a narrow strip type dynamic weighing system comprises a first sensor assembly 1 and a second sensor assembly 2 which are sequentially embedded on a weighing lane along a driving direction, a ground sensing coil 3 is arranged between the first sensor assembly 1 and the second sensor assembly 2, the first sensor assembly 1 and the second sensor assembly 2 both comprise two first narrow strip sensors 4 which are sequentially arranged along the driving direction, a third sensor assembly 5 is arranged on one side of the second sensor assembly 2 far away from the ground sensing coil 3, and the third sensor assembly 5 comprises two second narrow strip sensors 6 which are sequentially arranged along the driving direction.
The utility model provides a narrow strip formula dynamic weighing system, still includes switch board 7, switch board 7 sets up in one side of second sensor subassembly 2, is provided with terminal box 8, controller 9 and controller display screen 10 in the switch board 7, and controller 9 is embedded industrial computer, and 4 first narrow strip sensors 4, 2 second narrow strip sensors 6 and ground induction coil 3's signal carries out data processing through terminal box 8 access controller 9 respectively, and controller 9 links to each other with controller display screen 10.
Because the narrow strip sensor adopts a point weighing technology, a time delay integral weighing mode is used for replacing a simultaneous integral weighing mode, and the instantaneous bearing force of the sensor is only about 1/5 of the actual weight of the tire when the narrow strip sensor is fully loaded. In addition, the strip sensor is added with a multi-point simultaneous weighing concept, so that the deformation amount is very small, and only 0.5mm of micro-deformation exists when the strip sensor is fully loaded, thereby congenital weighing errors caused by the deformation of the sensor are avoided, and self-excited vibration of the running vehicle is also removed.
