To provide a weight measurement system and a vehicle separation method that can measure the weight per vehicle with a simple configuration.SOLUTION: A weight measurement system 100 comprises: a detection signal acquisition unit 111 that acquires detection signals for each wheel output from a plurality of wheel load sensors arranged in the direction of travel A of a vehicle 200; a wheel load calculation unit 112 that calculates the speed of travel and wheel load of the wheels on the basis of the acquired detection signals; a separation determination unit 114 that determines, for each of the wheel load sensors, whether the wheel load corresponding to the wheel load sensor is the wheel load for the same vehicle 200, on the basis of the speed of travel and the wheel load of a preceding wheel and the speed of travel and the wheel load of a subsequent wheel, which are acquired; a vehicle separation unit 115 that separates the wheel load for every vehicle on the basis of a result of determination made by the separation determination unit 114; and a weight measurement unit 116 that measures the weight of the vehicle on the basis of the separated wheel load for every vehicle.SELECTED DRAWING: Figure 1 【課題】簡易な構成により車両１台毎の重量を計測することが可能な重量計測システム及び車両分離方法を提供する。【解決手段】重量計測システム１００は、車両２００の走行方向Ａに配置された複数の輪重センサから出力される車輪毎の検出信号を取得する検出信号取得部１１１と、取得された前記検出信号に基づいて前記車輪の走行速度及び輪重を算出する輪重算出部１１２と、算出された先行車輪の前記走行速度及び前記輪重と後行車輪の前記走行速度及び前記輪重とに基づいて前記輪重センサ毎に当該輪重センサに対応する前記輪重が同一の車両２００の輪重であるか否かを判定する分離判定部１１４と、分離判定部１１４の判定結果に基づいて前記輪重を前記車両１台毎に分離する車両分離部１１５と、分離された前記車両１台毎の前記輪重に基づいて前記車両の重量を計測する重量計測部１１６と、を備える。【選択図】図１
