The invention discloses a rail transit vehicle multi-sensor monitoring method, device and system, and belongs to the field of rail transit automatic control, and the method comprises the steps: reading multi-sensor monitoring data; calculating a relation matrix, and judging whether the measurement data of the multiple sensors are consistent or not by utilizing the relation matrix; searching a sensor group with the highest mutual support degree according to the relation matrix; if the mutual support degree is judged, blending the measurement data of the sensor group by adopting a self-adjusting weighting algorithm, and recording the blending result as the measurement data of the composite sensor; if the judgment of the mutual support degree is not passed, the following processing is performed: the number of the composite sensors is judged, and if the number of the composite sensors is greater than 1, a sensor measurement value with high fusion precision is selected as a final fusion result; if the number of the composite sensors is equal to 1, the measurement result of the composite sensors is the final blending result. The reliability and the accuracy are improved, and the actual rail transit vehicle application requirements are met.
本发明公开了一种轨道交通车辆多传感器监测方法、装置及系统,属于轨道交通自动控制领域,包括步骤:读入多传感器监测数据;计算关系矩阵,利用关系矩阵判断多传感器测量数据间是否具有一致性;根据关系矩阵,寻找相互支持度最高的传感器组;如果通过相互支持度的判定,则将传感器组的测量数据采用自调节加权算法交融处理,将交融结果记为复合传感器的测量数据;如果未通过相互支持度的判定,则作如下处理:判断复合传感器数量,若复合传感器数量大于1,则选取交融精度高的传感器测量值为最终交融结果;若复合传感器数量等于1,则该复合传感器的测量结果为最终交融结果。本发明提高了可靠性和准确度,满足实际轨道交通车辆运用要求。
