This document
is
a
report on
the
feasibility
study
conducted
on the
proposed
solutions
for
the
Planet Tracking Software.
这份文档是关于行星追踪软件若干解决方案的可行性研究报告
b)
The
software
should
be
able
to
control
the
motors
such
that
the
mirrors
and
the
unit
can
be
aligned in all desired
configurations.
这个软件应该可以控制电机,使镜体和跟踪仪可以在
所有预想配置下对齐。
c)
The
first technical constraint that was considered for
coming up with the possible solutions was
that the system has to work on the
Windows operating system.
对于备选的解决方案,
第一个需要考虑的技术限制是系统必须运行在
Windows
操作系统上。
d)
The
advantage
of
this
solution
is
that
all
5
members
of
the
group
are
well-
versed
in
the
programming language chosen.
这个解决方案的优点是小组内的
5
名成员都十分精通所选定的
编程语言。
e)
Under
the
proposed
scenario,
the
user
would
be
able
to
take
up
to
100
measurements
a
day
depending
on what type of measurement is being taken.
在该场景下,用户一天应能进行多达
100
次测量,
具体数目取决于测量类型。
f)
Hence this solution does not translate
into a learning curve for any of the members.
因此这项解决方案对于组员来说没有学习上的难度。
g)
The
second
critical
section
is
where
the
code
determines
the
coordinates
of
a
celestial
object
using the time provided.
第二个关键之处在于使代码根据提供的时间来确定星体坐标。
h) As is apparent from the Gantt chart,
accommodating the time required to develop the
plug-in leads
to conflict with the
deadlines.
从甘特表中可以清楚地看到,开发插件所需的时间将会和截止时
间发生冲突。
a)
The objective
of this Software Development Plan is to define the
development activities in terms
of the
phases and iterations required for implementing a
computerized class registration system
for Zhonghua University.
这份软
件开发计划的目的是从实施中华大学计算机化课程注册系统所需的开发阶段和迭代
周期等
方面详细说明诸多开发活动。
b)
This
Software
Development
Plan
describes
the
overall
plan
to
be
used
by
General
Computers
Corporation for developing the Course
Registration System for Zhonghua University.
这份软件开发计划描述了通用电脑公司为中华大学开发计算机化课程注册系统的整体计划。
c)
Other
artifacts
will
be
produced,
as
described
in
the
project
development
case,
but
are
not
intended to be delivered
to the maintenance organization.
正如项目开发
样例中指出的,会产生其它一些工件,但不会把它们交付给维护机构。
d)
The
Course
Registration
System
is
similar
in
complexity
and
architecture
to
the
Online
Library
System, built for
Zhonghua University in 1999.
这个课程注册系统与<
/p>
1999
年为中华大学构建的在线图书馆系统在复杂性和整体结构
上类似。
e)
A Work Breakdown Structure is being
prepared, and will be provided in the next version
of this
document.
任务分解体系正在准备当中,并将出现在该文档的下个版本中。
f)
Each phase consists of
development iterations in which a subset of the
system is developed
每一阶段包括若干开发迭代周期,各周期开发整个系统的子集
.
f)
To
accommodate
the
changes,
Rational
RequisitePro
will
be
used
to
manage
the
product
requirements and to
keep track of release content.
为了适应变化,将采用
Rational Requisite
Pro
来管理产品需求并记录发布版本内容。
h) In addition, there will be internal
releases, to maintain a regular heartbeat to help
keep the project
on track, and to allow
for the possibility of additional releases after
the initial release, if needed.
另外,将会发布
内部版本,以保持常规步调,保证项目走在正轨上,如果需要的话,也能保
证初次发布之
后继续发布的可能性。

、
VTS
is started and it starts TCP listener at the
specified IP and Port, and loads all VT IMEI from
database;
车辆跟踪系统启动后将在指定的
IP
地址和端口号启动一个
TCP
监听程序,
并从数据库中载入
所有车辆跟踪器的
p>
IMEI
;
2
、
The
VT is powered on and comes into GPRS coverage
areas, and then the VT attaches to the GPRS
network and creates an active GPRS
connection;
车辆跟踪器在电源启动后,如果进入
GPRS
覆盖范围,它就能接入
GPRS
网络并且激活
GPRS
连接。
3
、
The
VT creates a TCP connection to the fixed IP and
Port, and VTS gets the connection request at
the listener and accepts the connection
车辆跟踪器创建一个
TCP
连接到固定
的
IP
地址和端口,车辆跟踪系统在监听端收到连接请
求并接受该连接;
4
、
The
VT
sends
login
message,
when
the
IMEI
of
the
VT
is
sent
as
the
id,
VTS
verifies
IMEI
and
decides to accept or
reject this connection;
车辆跟踪器发送登录消息,
以
IMEI
作为身份码,
车辆跟踪系统验证
IMEI
并决定接受还是拒
绝该连接;
5
、
Connection is set up, and VT sends
Location Record in T-TCP protocol to the VTS;
连接建立后,车辆跟踪器通过
T-TCP
协议向
车辆跟踪系统发送位置记录;
6
、
The
VTS gets Location Record, sends location to G-Tech
Server by GTHttpRequest class, and gets
return in XML format;
车辆跟踪系统
收到位置记录并将其通过
GTHttpRequest
类发送给
G-Tech
服务器,
再接收
XML
格式的返回信息;
7
、
The VTS
processes the returned address info from G-Tech
Server and sends address info to the
LCS;
车辆跟踪系统处理
G-Te
ch
服务器返回的地址信息,并将其发送给位置信息收集系统;
8
、
If the LCS
needs to send command to the VTS, the VTS will
encode command and send encoded
command
to the particular VT.
如果位置信息收集系统需要向车辆跟踪
系统发出命令,
车辆跟踪系统会对命令进行编码,
然
后将编码后的命令发送给特定的车辆跟踪器。
