Built-in control system of special gate for rail traffic

Abstract

An embedded control system for special turnstile for track traffic has a control center of the system constructed by closely combining an embedded ARM9200 CPU used as core control chip with a DCU-1 hardware module and DCU-2 hardware module; extremely strong real-time responsibility; a hardware system with modularized design and high integration; a hardware module with bus structural connection; parallel high-activity processing of system with separated service process and equipment control which operated independently and simultaneously; a multifunctional TFT passenger display; multiple demotion operating modes; function of sleep for saving energy and electricity; functions of remote monitoring, remote diagnosis, and repairing; and a designed powerful integrated simulation test platform matched with the control system of the gate machine.

Description

technical field [0001] The invention belongs to a rail transit ticket checking computer control system, in particular to an embedded control system for a rail transit special gate. Background technique [0002] Rail transit special gate (AGM) is an important equipment in the underground railway fare collection system (AFC). It is the only open channel between the paid area and the non-paid area in the subway station hall. One-way tickets are directly subject to deduction transactions and automatic ticket inspection, and automatic management and monitoring of passenger entry and exit channels are implemented. [0003] The special gate products for rail transit before the present invention all adopt general-purpose industrial control computer as its core control module, and the real-time performance is low. Sometimes the system crashes and crashes, requiring a system restart. In addition, due to the different subway operation and ticket management rules in each city, there a...
