Subway carriage passenger carrying condition early warning and guiding system

Abstract

The invention discloses a subway carriage passenger carrying condition early warning and guiding system, and the system comprises: a sensor detection system. which acquires the current pedestrian volume in each carriage of a subway which is about to enter a station; a PLC control system, which is internally equipped with a preset congestion level module to accurately divide the congestion level ofthe carriage; the PLC control system outputs a control signal to control an indicator light system to give a prompt according to the current pedestrian volume obtained by the sensor detection systemand the congestion level output by the congestion level module. A human body infrared intrusion detection sensor is adopted to judge the situation that passengers enter and exit from a carriage; a proximity sensor at the exit of the subway carriage is used for completing final detection to confirm whether passengers get on the vehicle or not; the number of passengers going in and out is calculatedthrough the PLC so as to judge the number of passengers in each carriage to obtain a corresponding pedestrian volume value area; and finally, different indicator lights in front of each carriage areturned on in different personnel number intervals, so that passengers outside the vehicle are reminded to avoid people flow congestion, and the purpose of evacuating people flow is achieved.

Description

technical field [0001] The invention relates to the technical field of carriage guidance, in particular to an early warning and guidance system and control method for passenger carrying conditions in subway carriages. Background technique [0002] In the mode of modern urban transportation, the subway is an efficient means of transportation, which can relieve the pressure of urban traffic congestion to a great extent. When people are waiting for a ride at a subway station, they don’t know the passenger situation in each car at the previous station, so passengers are blind when choosing the position of the entrance and exit of the car, resulting in crowded traffic in the waiting area of ​​the subway platform, and the time for passengers to get on and off the bus is limited. There will be 2 minutes, which will make it difficult for some passengers to get on and off the car, and there will be uneven passenger capacity in each car. When the passenger flow is too large, the possi...

Problems solved by technology

When people are waiting for a train at a subway station, they don't know the passenger situation in each carriage at the previous station, so passengers are blind when choosing the position of the entrance and exit of the carriage, resulting in crowded traffic in the waiting area of ​​the subway platform, and the time for passengers to get on and off the train is limited. There will be 2 minutes, which will make it difficult for some passengers to get on and off the car, and there will be uneven passenger capacity in each car. When the passenger flow is too large, the possibility of safety problems will increase
