Summary: | PROBLEM TO BE SOLVED: To more smoothly obtain weight information for a vehicle at lower cost than ever before.SOLUTION: A weighing unit 10 of a vehicle weighing device relating to the invention comprises: a weighing platform 12 that can simultaneously mount all wheels of a vehicle as a weighed object; and multiple load cells 14 that support this weighing platform 12. Three tape switches 16 are arranged on the weighing platform 12. Respective distances L5, L7 and L9 from a reference position Pa of the weighing platform 12 to the individual tape switches 16 are already known. The vehicle moves on this weighing platform 12 at low speed and a proper wheel of the vehicle turns on the tape switches 16 during the process. The vehicle weighing device obtains weight information for the vehicle, especially an axle weight value that is an applied load value to each axle, on the basis of each detected load value by the load cells 14 at each turn-on time and the respective distances L5, L7 and L9 from the reference position Pa of the weighing platform to the individual tape switches 16.
【課題】 従来よりもスムーズにかつ低コストで車両の重量情報を求める。【解決手段】 本発明に係る車両計量装置の計量部10は、被計量物としての車両の全車輪が同時に載置可能な計量台12と、この計量台12を支持する複数のロードセル14と、を備えている。また、計量台12上には、3つのテープスイッチ16配置されている。なお、計量台12の基準位置Paから各テープスイッチ16までの距離L5,L7およびL9は、既知である。車両は、この計量台12上を低速で移動し、その過程で、当該車両の適宜の車輪によって各テープスイッチ16がオンされ、その時々の各ロードセル14による荷重検出値と、計量台12の基準位置Paから各テープスイッチ16までの距離L5,L7およびL9と、に基づいて、車両の重量情報が求められ、特にそれぞれの車軸への印加荷重値である軸重値が求められる。【選択図】 図1 |
