方案2：Scenario 2:
针对地面信息获取单元接收到停车预警信息的情况，控制单元通过显示单元提示司机确认停车预警信息，若控制单元超过设定时间未收到司机的确认指令，则控制单元自动触发安全停车区自动停车功能，具体包括：In response to the situation that the ground information acquisition unit receives the parking warning information, the control unit prompts the driver to confirm the parking warning information through the display unit. If the control unit does not receive the driver's confirmation command within the set time, the control unit automatically triggers the safe parking area to automatically park. Features, including:
控制单元计算出位置D,位置D＝安全停车区起点位置+列车长度；The control unit calculates the position D, and the position D = the starting position of the safe parking area + the length of the train;
控制单元自动向列车输出加速命令，目的是让列车以最高允许速度运行，以最短时间尽快停车在安全停车区，控制单元根据位置D生成最大常用制动曲线(图中的S2曲线)，控制单元判断列车速度是否超过最大常用制动曲线，若控制单元判断列车速度超过最大常用制动曲线，则控制单元向列车施加最大常用制动，控制列车停靠在安全停车区范围内；同时，控制单元根据安全停车区终点位置生成紧急制动曲线(图中的S1曲线)，控制单元判断列车速度是否超过紧急制动曲线，若控制单元判断列车速度超过紧急制动曲线，则控制单元向列车施加紧急制动，控制列车停靠在安全停车区范围内。The control unit automatically outputs an acceleration command to the train, the purpose is to let the train run at the highest allowable speed and stop in the safe parking area as soon as possible in the shortest time.

方案3：Scenario 3:
针对地面信息获取模块接收到停车预警信息的情况，控制单元通过显示单元提示司机确认停车预警信息，若控制单元超过设定时间未收到司机的确认指令，则控制单元暂 时不作处理，控制单元判断列车速度是否超过根据安全停车区终点位置生成的紧急制动曲线，若控制单元判断列车速度超过控制单元通过安全停车区终点位置生成的紧急制动曲线，则控制单元向列车施加紧急制动，控制列车停在安全停车区范围内。In response to the situation that the ground information acquisition module receives the parking warning information, the control unit prompts the driver to confirm the parking warning information through the display unit. If the control unit does not receive the confirmation command from the driver within the set time, the control unit will not process it temporarily, and the control unit judges Whether the train speed exceeds the emergency braking curve generated according to the end position of the safe parking area, if the control unit judges that the train speed exceeds the emergency braking curve generated by the control unit through the end position of the safe parking area, the control unit applies emergency braking to the train and controls The train stops within the secure parking area.
作为优选实施例，为了防止显示单元显示过多信息，从而对司机驾驶列车造成干扰，安全停车区的位置信息也可以不用在显示单元上实时显示，在地面信息获取单元未收到停车预警信息时，控制单元允许不在显示单元上显示安全停车区的位置信息，比如在地面信息获取单元未收到停车预警信息时，司机可以关闭显示单元显示的安全停车区的位置信息；As a preferred embodiment, in order to prevent the display unit from displaying too much information, thereby causing interference to the driver driving the train, the location information of the safe parking area may not be displayed on the display unit in real time. When the ground information acquisition unit does not receive the parking warning information , the control unit is not allowed to display the location information of the safe parking area on the display unit. For example, when the ground information acquisition unit does not receive the parking warning information, the driver can turn off the location information of the safe parking area displayed by the display unit;
但在地面信息获取单元收到停车预警信息时，控制单元控制显示单元持续显示安全停车区的位置信息，即不允许关闭显示单元显示的安全停车区的位置信息。However, when the ground information acquisition unit receives the parking warning information, the control unit controls the display unit to continuously display the location information of the safe parking area, that is, the location information of the safe parking area displayed by the display unit is not allowed to be turned off.
