Abstract

Automatic ticketing system (AFC) is based on computer, communication, network,

automatic control technology, such as

rail transit ticket, ticket, billing and charging,

statistics, management and so on the whole process of the automation system

Along

with

the

network

popularization,

the

vending

machine

has

important

significance in the international and domestic, big to rail transport industry, small to

the cinema application of the principle of automatic machines are automated.

,

on

the

basis

of

reliability

analysis

of

the

existing

system

of

several

method

can

improve the system reliability were studied, the main research contents include: 1, the

original

railway

ticketing

system

are

analyzed

architecture

less

than

shortcomings,

such

as

reliability,

put

forward

by

using

the

method

of

optimization

of

railway

ticketing system architecture for the

growth of the system reliability, the module of

the

method

in

the

original

architecture

components

failure

probability

under

the

premise

of

stable,

build

system

by

using

a

load

balancer

server

cluster

service,

effectively

prolong

the

time

interval

between

the

average

of

the

system

operation

trouble-free, improves the system reliability and availability. 2, the movement process

of

the

railway

ticketing

system,

service

process

due

to

the

background

in

the

SC

abnormalities, system resources occupancy rate is too high, and database performance

causes such as railway ticketing system software failure phenomenon, put forward a

kind

of

through

the

establishment

of

the

supervisory

control

subsystem

of

railway

ticketing method to

enhance the

reliability of the system. This

method is helpful to

maintenance personnel to understand the system real-time working state, to maintain

the

system

in

a

timely

manner,

so

as

to

extend

the

system

average

trouble-free

working time, improve the system reliability and availability. 3, in view of the railway

ticketing system maintenance difficult problems in the process of operation, proposes

the establishment

of railway ticketing system

fault diagnosis expert subsystem. The

method

based

on

the

existing

railway

ticketing

management

system

upgrade

the

simple function, can realize quick positioning of system failure and put forward the

solution

of

failure,

reduce

the

difficulty

of

the

maintenance

work,

reduced

the

time

needed for system maintenance work, improve the system availability.

聽

On how to make the automatic ticketing system become a popular way to buy tickets,

and how to

avoid

the system error, the braking

principle of machines is

of obvious

significance to solve the problem.

The whole circuit principle of work is

not

very

complex, can be analyzed from

the

following diagram out how it works, also can see that the circuit can be summarized

as the following sections:

1. The motor drive part

2. Signal feedback part

3. The command signal to the issue of a bill

4. Manual ticket section

Manually

drawn

part

of

the

article

also

summarizes

the

problems

existing

in

the

vending machine and the corresponding system solutions
