Passenger alarm output control circuit of unmanned subway train

Abstract

The invention relates to a passenger alarm output control circuit of an unmanned subway train. A passenger emergency alarm device is installed on the train, and the passenger emergency alarm device isprovided with alarm buttons and alarm relays which are in linkage with the alarm buttons, correspond to the alarm buttons one to one and are provided with normally-closed contacts; when the alarm buttons are pressed, the alarm relays are electrified to make the normally-closed contacts of the alarm relays switched off, the normally-closed contacts of the alarm relays of all passenger rooms are connected in series to form an emergency alarm line, and the two ends of the emergency alarm line are connected with a train power supply and an input / output module of a TCMS of the passenger rooms respectively. When a passenger information system works normally, alarm signals can be transmitted through a communication network and can also be transmitted through hard wires, and when the alarm signals are not consistent, the hard wire alarm signals are prior. When the network breaks off, the hard wire alarm signals serve as redundancies, the alarm signals can still be output, and the reliabilityof the system is greatly improved.

Description

technical field [0001] The invention relates to the control of a passenger information system of a fully automatic unmanned subway vehicle, in particular to a method for controlling an alarm output to passengers in an unmanned subway train. Background technique [0002] With the improvement of the digitization of the train passenger information system, the communication between devices is transmitted through the bus, and the reliability of data transmission depends entirely on the logical reliability and stability of the software. [0003] For the passenger information system, the most critical function is the passenger emergency alarm. In any case, the driver / OCC can keep abreast of the situation in the passenger compartment and know that a passenger has called for the alarm. In unmanned driving mode, when the communication between the passenger information system and the train network system (TCMS) fails, the passenger's call cannot be transmitted. Each car is equipped wi...

AI Technical Summary

Problems solved by technology

Due to the use of fully automatic unmanned driving, when the software is unstable or unreliable, the passenger alarm signal cannot be output, and there will be operational safety hazards

Once in an emergency, the passenger's alarm cannot be output to TCMS, and TCMS cannot send the information to OCC, resulting in the interruption of communication between OCC and passengers, which may cause serious accidents such as casualties, and there are potential safety hazards
