摘要
为提高紧急救援站停车导向标志的可读性,综合考虑诱导活塞风的要求,研究其与线路中线合适的交叉角度;根据停车导向标志的可读性,研究列车进入紧急救援站导向区间及停车区间的行车速度。根据停车导向标志的功能,首先确定火灾列车驶向紧急救援站时驾驶员对停车导向标志的认读、判断及采取措施的过程;通过现场试验确定不同角度情况下的停车导向标志与给读点间的距离;通过计算确定不同车速情况下驾驶员从容读完标志,做出正确判断并将列车准确停靠所需的最短距离。研究结果:(1)驾驶员使用停车导向标志需经过发现、识别、判断和行动四个步骤,以调整火灾列车的行驶状态,最终安全、准确、顺利地将火灾列车停靠在紧急救援站内;(2)停车导向标志与线路中线的夹角越大,其与可读点间的距离则越大;(3)列车行驶速度越快,驾驶员做出正确识别、判断和行动所需的距离越长。研究结论:(1)停车导向标志与线路中线的夹角以30°为宜;(2)火灾列车进入紧急救援站导向区间时,车速应控制在80 km/h以下;(3)火灾列车进入紧急救援站内时,车速应控制在30 km/h以下。
In order to improve the readability of stop signs in emergency rescue stations,appropriate crossing angle between the signs and the central line is studied in consideration of the requirements of induced piston wind.According to the readability of stop signs,the speed of trains entering the guidance section and parking section of emergency rescue station is studied.According to the function of stop signs,the process of driver's recognition and judgment to the stop sign and taking actions is determined when fire train is heading for the emergency rescue station.Through field tests,the distance between the stop sign and the reading point under different angles is determined.The shortest distance required for the driver to read the sign calmly,make correct judgments and stop the train accurately at different speeds is determined based on calculations.Research results:(1)When using stop signs,drivers need to go through four steps:discovery,identification,judgment and action to adjust the running state of the fire train,and eventually stop the in the emergency rescue station safely,accurately and smoothly.(2)The larger the angle between the stop sign and the central line,the greater the distance between the stop sign and the readable point.(3)The faster the train travels,the longer distance the driver needs to make correct identification,judgment and action.Research conclusions:(1)The angle between the stop sign and the central line should be 30 degrees.(2)When a fire train enters the guidance section of an emergency rescue station,its speed should be controlled below 80 km/h.(3)When a fire train enters into an emergency rescue station,its speed should be controlled below 30 km/h.
