The invention discloses a subway communication device, which comprises a vehicle body shell, wherein a movable door is slidably connected to the vehicle body shell, a rectangular cavity is formed in the vehicle body shell, first mounting cavities are formed in the upper side wall and the lower side wall of the rectangular cavity, and limiting columns are fixedly connected into the first mounting cavities located in the upper side wall of the rectangular cavity. When the movable door is closed, air compression is generated through a corrugated air bag to serve as driving force, a conductive coil is driven to rotate, induced current is generated, magnetism is generated after current enters an electromagnet to attract magnetic sheets, it is normal when a driver sees that all the magnetic sheets are attracted to the electromagnet, starting cannot be performed when one of the magnetic sheets is not attracted, the compartment with the problem can be known through a corresponding label, and an interphone is used for informing, so that the driver does not need to get off to see the gesture of a trainman and then move, and a lot of time is saved. Meanwhile, the burden of the trainman and the driver is reduced, and the work is facilitated.
本发明公开了一种地铁通讯装置,包括车体壳体,所述车体壳体上滑动连接有移动门,所述车体壳体上开设有矩形腔,所述矩形腔的上下两侧壁均设有第一安装腔,位于矩形腔上侧壁的所述第一安装腔内固定连接有限位柱。本发明当移动门关起的时候通过波纹气囊产生空气压缩作为驱动力,带动导电线圈转动,产生感应电流,电流进入电磁铁之后产生磁性从而吸附磁性片,驾驶者看见所有磁性片均吸附到电磁铁的时候便一切正常,当其中一个磁性片没有被吸附,便不可启动,同时通过对应的标号可以知道哪个车厢出现问题,利用对讲机告知,这样就不需要驾驶者下车看乘务员的手势然后再行动,节约了大量的时间,同时减小乘务员和驾驶员的负担,方便工作。
