Problems solved by technology

[0003] At present, the subway train automatic control system is very mature, but there are often times when the subway enters the station, the speed of the train is not smooth, and passengers will be unstable due to inertia, and sometimes the location of the subway stop deviates from the target required location, making the shielding The door and the subway door cannot be completely aligned, which may cause inconvenience for passengers getting on and off the train, or cause personal safety and traffic accidents

Abstract

The invention discloses a subway train inbound speed control method and positioning monitoring system. The subway train positioning monitoring system comprises positioning terminal equipment located in a subway platform area, and a train automatic control system located at the control center; the positioning terminal equipment comprises a radar speed tachymeter, a first position monitoring unit, asecond position monitoring unit, a third position monitoring unit, a camera unit, a main controller and a wireless transmission unit; position information, train speed information and stop real-timeimage information of a subway train in the inbound stopping process are collected through the positioning terminal equipment; the train automatic control system conducts three-stage PID train speed adjusting and computing according to the collected subway train position information and the train speed information, sends a subway train speed adjusting control command, and controls the subway trainto stop within the safe range stably, and the bumping feel is relieved; and in addition, a subway train all-dimensional stop image is generated through the information, and the stop state of the subway train is simulated.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method for controlling the speed of a subway train entering a station and a positioning monitoring system. Background technique [0002] As a safe, fast, large-capacity, low-energy, and less-polluting urban rail transit, the subway is an effective means of transportation to relieve urban traffic pressure and reduce air pollution. How to ensure the safety of subway operation has become a top priority. [0003] At present, the subway train automatic control system is very mature, but there are often times when the subway enters the station, the speed of the train is not smooth, and passengers will be unstable due to inertia, and sometimes the location of the subway stop deviates from the target required location, making the shielding The door and the subway door cannot be completely aligned, which may cause inconvenience for passengers getting on and off the train, and ...
