Subway train alarm system

Abstract

The invention provides a subway train alarm system, comprising a host and slaves. The host is arranged in the driver cab, the multiple slaves are arranged in compartments, and the multiple slaves arehung on a vehicle-mounted CAN bus and are in communication connection with the host through the vehicle-mounted CAN bus. Each slave comprises a slave control unit, a button unit, a slave sound and light alarm unit and a slave CAN communication unit. The host comprises a host control unit, a host CAN communication unit, a host sound and light alarm unit, a clock unit, a display unit, a keyboard input unit and a storage unit. The subway train alarm system is based on the single-chip microcomputer control and the CAN bus communication technology and adopts a host-slave CAN bus communication mode,passengers in the compartments can actively give out an alarm, and the crew member can also take response measures to the alarm information at the first time, thereby preventing asymmetry of information transmission, the security is improved, and the subway train alarm system can be widely applied to other security situations.

Description

technical field [0001] The invention relates to the technical field of subway security, in particular to a subway train alarm system. Background technique [0002] As one of the main rail transportation methods in the city, the subway has a large number of people, and its security measures should be taken seriously. Existing subway security is mainly implemented in the subway platform. For example, when accidents such as fire, fight or stampede occur in the platform, the alarm equipment in the platform will send out an alarm to remind passengers to evacuate as soon as possible to reduce injuries as much as possible. [0003] For abnormal emergencies in the subway train compartment, in the prior art, by setting a camera in the compartment, the video data in the compartment can be obtained in real time, and the video data is transmitted to the monitor installed in the train cab, and the passengers pass the monitoring monitor to view the surveillance video in each compartment....

AI Technical Summary

Problems solved by technology

Therefore, when fights, stampedes, or even malicious injuries occur in the compartment, or because the screen is too small to see clearly, or because the screen is not displayed in real time, or because the passengers are not found in time due to human factors, the passengers will not be able to Take timely countermeasures at the first time, thus causing safety hazards
