[0002] The alarm device of EMU usually consists of a train monitoring system and a train protection system. These systems monitor the operation of the train through communication between on-board equipment and track equipment, and take control measures when necessary to ensure the safe operation of the train. Its main function is to monitor the speed, position and other relevant parameters of the train, and issue an alarm when an abnormal situation occurs, or take measures such as automatic braking when necessary to avoid accidents.

[0003] The alarm device of the EMU usually covers the entire train, monitoring the speed, position and other relevant parameters of the train. Its scope of action includes but is not limited to monitoring the distance between vehicles, whether the train deviates from the track, whether the train is speeding, and whether the train is approaching the signal light. Once an abnormal situation is found, the alarm device will sound an alarm in time and take corresponding control measures as needed to ensure the safe operation of the train. The problem with the above technology is that it is usually necessary to install multiple alarm devices in the EMU for use and electrically connect them to the monitoring to achieve the effect of monitoring the alarm. However, when installing the alarm device, it is necessary to use multiple accessories and connection structures for fixing. The installation process consumes a long time and energy of the user, thereby reducing the convenience of installation of the alarm device. After the alarm device is used for a certain period of time, it needs to be regularly dismantled, maintained and inspected to avoid abnormal situations. However, it is not convenient to install and dismantle the alarm device, which will cause certain troubles in the inspection process. Utility Model Content
