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...

AI Technical Summary

Problems solved by technology

[0003] The special gate products for rail transit before the present invention all use general-purpose industrial control computers as their core control modules, which have low real-time performance. Under the impact of large passenger flow, ticket business and transaction processing are complicated, and gate failures are very likely to occur, which is serious. Sometimes the system crashes and crashes, and the system needs to be restarted.

In addition, due to the different subway operation and ticket management rules in each city, there are also differences in the functional requirements of the gates. In the past, gate manufacturers had to change the control design frequently according to the needs of different cities, which made the production process cumbersome and complicated. The production of the door mechanism is separated from the production of the gate control system, which must be completed with the assistance of different manufacturers

As a result, the placement of the internal modules of the gate is chaotic, the modules take up a large space, and the wiring is complicated. At the same time, it also makes the maintenance and fault repair of the gate very inconvenient, and the production cost increases.
