System of urban track traffic for passenger flow monitor and emergency evacuation

Abstract

The invention discloses a system of an urban track traffic for passenger flow monitor and emergency evacuation in the technical field of subway passenger flow security guarantee, which has the technical scheme that the system comprises a hardware part and a software part; the hardware part comprises a station camera, a multi-channel video switching controller, a high-speed image data acquisition processor, a station dispatching centre processor and a line network command center processor; the station camera is connected with the high-speed image data acquisition processor through the multi-channel video switching controller; the high-speed image data acquisition processor is connected with the station dispatching centre processor which is connected with the line network command center processor; and the software part comprises a digital video imaging and analyzing programme, a station passenger flow monitor and emergency evacuation system and a line network passenger flow monitor and emergency evacuation system. The system monitors the passenger flow volume and the passenger flow distribution in a real-time manner, and can start up the emergency handling process automatically to adjust a service system as needed in a real-time manner.

Description

technical field [0001] The invention relates to the technical field of subway passenger flow safety assurance, in particular to an urban rail transit passenger flow monitoring and emergency evacuation system. Background technique [0002] Urban rail transit is the industry with the largest construction scale and the fastest development in my country in the next ten years, and has strategic and decisive significance for my country's social and economic development. More than a dozen cities, including Beijing, Shanghai and Guangzhou, are forming huge underground rail transit networks. The particularity of this line network lies in the poor controllability of passenger flow, strong mutation, and poor evacuation conditions in complex environments. From the perspective of actual demand at home and abroad, since most of the urban rail transit network operates in closed underground areas, it is necessary to strengthen the monitoring of real-time passenger flow, alleviate the impac...

AI Technical Summary

Problems solved by technology

When a delay occurs, the delayed passenger flow will be generated in the entire rail transit network. At a large transfer station where multiple lines meet, these passengers may change their travel (transfer) route, making the passenger flow in the entire rail transit network again. The distribution will lead to a sudden increase in the passenger flow of some lines, and a large number of passengers will be stranded at the station in a short period of time, and the longer the delay time, the more people will be stranded, which will prolong the delay time and form an urban rail transit passenger flow transportation vicious circle of

What's more serious is that even if there is a large passenger flow impact, the operation and management personnel still cannot accurately grasp the actual number of people at the station. The number of foot traffic that can be obtained by observing the monitor continuously

This method of relying entirely on manual estimation has high work intensity and poor accuracy

At the same time, it is difficult for these technical means to automatically provide emergency response optimization decision support functions in emergency situations
