Research on Multi-channel Gate Control of Urban Rail Transit Based on Improved SSD Algorithm

摘要:

城市轨道交通多通道闸机独立工作，对多个闸机精准控制难度较大，所以研究基于改进SSD算法的城市轨道交通多通道闸机控制方法。根据SSD算法应用流程生成先验框，再联合损失函数对基础SSD算法进行改进，利用改进后的SSD算法融合处理闸机数据。结合闸机数据融合处理结果确定闸机设备阵列布置，根据通行目标识别结果和传感器设备确定闸机通道内的通行情况，根据通行情况设计多通道闸机控制误动控制的处理子程序，完成城市轨道交通多通道闸机控制。实验结果表明，改进SSD算法作用下，闸机闭合状态始终与行人的当前行进方向保持一致，实时通过率较高，能够解决因闸机错误闭合而导致城市轨道交通混乱的问题。

Abstract:

The independent operation of multiple channel gates in urban rail transit makes it difficult to accurately control multiple gates. Therefore, a control method for multiple channel gates in urban rail transit based on an improved SSD algorithm is proposed. According to the application process of the SSD algorithm, prior boxes are generated, and the basic SSD algorithm is improved by jointly optimizing the loss function. The improved SSD algorithm is used to fuse and process gate data, and the layout of the gate equipment array is determined based on the results of the data fusion processing. The passage situation in the gate channel is determined based on the recognition results of the passage target and the sensor equipment, and a sub-program for error motion control is designed according to the passage situation to complete the control of multiple channel gates in urban rail transit. The experimental results show that, under the action of the improved SSD algorithm, the closed state of the gate is always consistent with the current walking direction of pedestrians, and the real-time passage rate is high, which can solve the problem of urban rail transit chaos caused by gate error closure.
