动车组自动报站功能测试方法

Test Method for Automatic Station Announcement Function of EMUs

动车组自动报站功能由旅客信息系统实现,主要负责列车即将到站、到站停稳、起步离站,三个时刻进行语音和文本的自动播报,从而向旅客传递列车的运行站点信息;当完成报站功能的开发或者修改,车次线路信息的增加或者修改时,均需要对修改内容进行验证;目前动车组旅客信息系统自动报站功能的测试方法较少,传统的测试方法由测试人员添乘跟车,在列车运行过程中对每一站的语音和文字播报进行观察,从而完成本车次的报站功能验证工作;这种测试方法效率非常低,依赖现场作业环境,并且测试回归性差;为了确保自动报站功能在运行过程中的稳定性,提升测试效率,采用GPS模拟软件,根据用户测试指令模拟列车实时位置,计算列车当前位置与一下站的距离;采用MVB数据收发装置,根据用户测试指令,模拟发送列车开关门信号、列车速度信号,完成以MVB为通讯方式的旅客信息系统自动报站测试;借助动车组自动报站功能的测试方法,可以提升测试效率,为自动报站功能稳定运行提供保障。

The automatic station announcement function of the electrical multiple units(EMUs)is realized by the passenger information system,which is mainly responsible for the automatic voice and text broadcast at three times when the train is about to arrive,arrives and stops stably,starts and leaves the station,so as to transmit the train operation station information to the passengers.When the station announcement function is developed or modified,and the train number line information is added or modified,the modified contents need to be verified.At present,there are few test methods for the automatic station announcement function of the passenger information system of EMUs.Traditional test methods are that the testers add passengers follow the train and observe the voice and text broadcasts at each station during the train operation,so as to complete the verification of the station announcement function of this train.This test method has the characteristics of poor efficiency,depending on the field operating environment,and poor test regression.In order to ensure the stability of the automatic station announcement function during operation and improve the test efficiency,GPS simulation software is used to simulate the real-time position of the train according to the user s test instructions,and calculate the distance between the current position of the train and the next station;The receiving and transmitting device of multifunction vehicle bus(MVB)data is adopted to simulate the sending of train door opening and closing signals and train speed signals according to the user s test instructions,so as to complete the automatic station announcement test of passenger information system using MVB as the communication mode;With the help of the test method of the automatic station announcement function of EMUs,it can improve the test efficiency and guarante the stable operation of the automatic station announcement function.
