重庆轨道AFC驱动主板模拟测试平台搭建

AFC(Automatic Fare Collection)系统是实现轨道交通售票、检票、收费、统计、清分、管理等全过程的自动化系统.半自动售票机(BOM)和自动售票机(TVM)在AFC系统中有着举足轻重的地位,而票卡传输控制驱动主板是它们中最重要的主板之一,也是故障率最高的主板.本文针对半自动售票机(BOM)和自动售票机(TVM)票卡传输控制驱动主板容易损坏,维修点无设备测试修好的主板的现状,综合运用了串口抓包、协议分析、单片机模拟发包等技术成功实现了对其测试平台的模拟.实践证明,模拟测试平台效果显著,非常具有借鉴意义.

Design Chongqing Rail Traffic AFC Drive Motherboard Simulation Test Platform

AFC (Automatic Fare Collection) system is an automated system for realizing the whole process of rail transit ticket, ticket checking, charging, statistics, clearing,management etc. Booking Office Ma-chine (BOM) and Ticket Vending Machine (TVM) in the AFC system take on a important position, and transmis-sion control drive motherboard of ticket card is one of the most important, and also is the highest failure device of them. This article for the Booking Office Machine (BOM) and Ticket Vending Machine (TVM) trans-mission control drive motherboard of ticket card is easy to damage, and is hard to repair without special repair equipment. The synthesis use of packet capture using serial port, protocol analysis, MCU simulation sending data package technology, we achieved successfully a simulation platform. The simulation test plat-form is effective solution for repairing transmission control drive motherboard, and very useful reference for other industry.
