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

Embodiment Construction

[0014] Embodiments of the present invention will be explained below in conjunction with the accompanying drawings.

[0015] For unmanned trains, one passenger emergency alarm unit (PECU) is installed in a pair of door areas of each passenger compartment. A-type subway trains have 5 pairs of doors and 5 passenger emergency alarm units (PECU) are installed. B-type subway trains have 4 pairs of doors. 4 PECUs. In addition, a PECU should be installed near the escape door of the driver's cab.

[0016] In this embodiment, the head car of the A-type subway train is used as an example, which has five pairs of doors and a driver's cab escape door. The passenger alarm output control circuit of the unmanned subway train includes passenger emergency alarm devices located near each pair of doors in the passenger compartment and near the escape door of the driver's cab. Each passenger emergency alarm device has an alarm button, a processor, and a Connected alarm speaker, camera, microphon...

Abstract

The invention relates to a passenger alarm output control circuit of an unmanned subway train. The train is equipped with an emergency alarm for passengers. The emergency alarm for passengers has an alarm button, and an alarm with a normally closed contact that is linked with the alarm button and corresponds one by one. Relay, when the alarm button is pressed, the alarm relay is energized so that its normally closed contacts are disconnected, and the normally closed contacts of the alarm relays in each passenger compartment are connected in series to form an emergency alarm circuit, and the two ends of the emergency alarm circuit are respectively connected to the train power supply and the passenger compartment The input / output module of the TCMS. When the passenger information system is working normally, it can transmit the alarm signal through the communication network and the hard line. When the two signals are inconsistent, the hard line alarm signal takes priority. When the network is interrupted, the hard-wire alarm signal is used as a redundancy, and the alarm signal can still be output, which greatly improves the reliability of the system.

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...
