First, present situation:
At present, the domestic electric power supervisory system
(contains, county level dispatch automated system, collection controls
station system, transformer substation supervisory system, power plant
NCS system and so on) the system structure to divide into the
following two kind of mainstreams type:
L high end system: Completely uses Unix +
RISC the CPU structure.
L low end system: Completely uses Windows +
X86 the CPU structure.
In recent years, in satisfied the user to the system performance
and under the secure request premise, for reduced the system
construction cost, had the strength the electric power automated
system to produce the factory to promote was called "mixes the
platform" the system one after another. Namely the server uses
Unix + RISC the CPU structure computer, the workstation uses Windows +
X86 the CPU structure computer, constitutes system.
Second, analysis:
1st, high end system fit and unfit quality:
Superiority: The system hardware movement stable, is
reliable; Unix operating system security good, the performance
is prominent.
Inferiority: The system construction cost is high,
requests high to the user maintenance; The life time maintenance
cost is high.
2nd, low end system fit and unfit quality:
Superiority: The system hardware price is inexpensive;
The Windows operating system may the serviceability be good,
maintains the background.
Inferiority: Windows operating system security, stability
bad, the virus emerges one after another incessantly, is easy to incur
the hacker attack, also system itself also keeps the back door which
has incurs divulges a secret.
3rd, mixes the platform the fit and unfit quality:
Superiority: The system hardware price is situated between
the high end to be systematic and between the low end system.
Inferiority: Set of movements systems simultaneously
dispose two kind of different hardware and software, requests high to
user's maintenance level. Has not been able fundamentally to
solve the RISC overhead construction computer maintenance cost soaring
fatal problem.
General, disposes RISC overhead construction CPU, moves the Unix
operating system small machine (to contain workstation and server
type) the price about 100,000 - 300,000 Renminbi, also computer
production factory limitation in IBM, SUN, HP these; But
performance nearly same PC X86 the overhead construction CPU
microcomputer (contains workstation and server type), its price about
10,000 - 50,000 Renminbi. Price difference in 6 - 10 times, even
is higher.
Because the present all electric powers automation factory
supervisory system product receives is restricted in only can dispose
on the small machine moves the Unix system, only can move the Windows
system reality on the microcomputer, created the user to be in a
dilemma the difficult position in the plan choice:
L wants to guarantee the movement the security and
the reliability, only can withstand the system the soaring
construction cost and the life time soaring maintenance cost;
L wants lower system construction cost and the life
time low maintenance expenses, only can accept the system movement the
stability and the secure aspect insufficiency.
Third, demand and reality:
In present situation, if has one kind of new automation
supervisory system solution, also can satisfy the user security and
the reliable request; Also can overcome the system price to be
soaring, the service cost high shortcoming, will certainly to receive
the user communities the welcome. Especially application
situation which simultaneously begins in the large quantities of
systems, enormously will save the user the investment, will reduce the
project construction cost and the maintenance cost.
Shenzhen Si Kaida controls the technical limited company, uses
the international newest computer hardware and the software
development technology, takes the lead in the monitoring domain to
promote brand-new PGC - the EX2000 system, completely solved the user
to be in a dilemma the difficult position. Has provided the
integrity series solution for the user from the low end system to the
high end system different demand.
The PGC-EX2000 system, except can be systematic, the high end
system as the conventional low end and "mixes the platform" outside
the movement, but also has provided other unique solution, namely:
The supervisory system uses the computer completely uses the X86
overhead construction the computer, namely PC machine hardware, but
the operating system completely uses the Unix operating system.
Like this disposes the system, has completely solved the former
supervisory system "the fish and the bear's paws cannot has both" the
condition, enable user first truly to have had the optimum performance
price ratio the product.
Electric power supervisory system moves which in this platform,
also has the high end system the performance and the security;
Also has the low end system the price superiority.
Achieves the high end system target in the performance index in
the situation, its overall price only quite Yu Gaoduan system 20% -
30%. Especially when a plan greater quantity system, or in the
transformation fund not too abundant situation, may save the massive
investments, reduces the life time maintenance cost.
Fourth, feasibility:
Sun Corporation, is the Unix camp's main factory. Based on
RISC system structure Solaris the series Unix operating system, always
is its SPARC small machine mainstream operating system, also is its
main profit method. Based on the Microsoft Windows formidable
pressure and persisted "the software end will realize the zero use
cost" the development idea, Sun Corporation has finally promoted
Solaris in November, 2004 which the expenditure large amount of money
research and development becomes 10 Unix operating system.
The Solaris10 biggest characteristic, was has realized is
compatible in SPARC CPU and on X86 CPU software. Namely the
movement in on the high price position Unix small machine based on X -
WINDOW contact surface software, after the source program passes
through retranslates, may the similar movement above the X86 Unix
system. Thus, by maturer, stable, the safe Unix operating system
substitutes the Windows operating system, to is maturer, stable and
the artistic X - WINDOW contact surface substitutes for Microsoft the
Windows contact surface, thus may enable the user thoroughly to get
rid of Windows the nightmare and the danger which brings in secure and
the stable aspect flaw, simultaneously avoids increasing user the
hardware expenses, even uses the free use after Solaris10 the way, the
user also may save the number not Philippines the purchase operating
system and the correlation software expense.
The PGC-EX2000 system, is Shenzhen Si Kaida controls the newest
automation supervisory system which the technical limited company
develops completes to develop the platform. In 1999 starts to
research and develop, in 2004 starts to invest the electrical power
system practical application.
The PGC-EX2000 system biggest superiority, is to the computer
hardware overhead construction and the operating system platform
widespread compatibility. As the graph foundation supports the
platform take Qt, take ANSI C + + as the software development kit, the
PGC-EX2000 system source code does not need to revise, may translate
the movement in all computer system. Regardless of is the X86
overhead construction, or RISC overhead construction. Regardless
of is the Windows operating system, Unix (including IBM AIX, HP TRU64,
SUN Solaris) operating system, perhaps each kind of edition Linux
(including Red Hat, Red Flag and so on). This widespread
compatibility, has provided each kind of most superior solution for
the user different application demand, simultaneously maintains the
system the function, the contact surface, the operation custom and the
maintenance uniformity.
The PGC-EX2000 system another major characteristic, was
according to the opening source code characteristic, the conformity
the relations database which came by the shareware development.
In in the high secure request situation, may construct
"(Linux/Solaris Unix) - the shareware database - supervisory system to
develop the platform by the operating system (PGC-EX2000)", three
levels completely open the source program to have the independent
intellectual property rights the application system, in under the
guarantee system operating efficiency premise, avoids the user the
danger which and the reliable worry and feasible appears to the
security.
Starts the PGC-EX2000 system from 2004 , already in
many places accent, county accent, 500kV transformer substation
supervisory system and power plant investment actual movement.
The movement hardware platform includes:
L IBM super small machine
L SUN super small machine
L HP Alpha super small machine
L X86 microcomputer and so on
The operating system platform includes:
L IBM AIX
L SUN SOLARIS
L HP TRU64
L Windows family and so on
According to the electrical power system at present
present situation, Shenzhen Si Kaida will control the technical
limited company in the near future to promote based on SUN Solaris 10
Unix + the X86 overhead construction system solution, provided "the PC
machine hardware investment + UNIX rank security, the stability and
the reliability" for the user the supervisory system. The
widespread use to the dispatch automated system, the collection
controls the station system, the 500kV transformer substation
supervisory system, the power plant NCS system and so on a series of
applications.
Fifth, system movement case:
First set of Solaris10 for under X86 environment transformer
substation computer supervisory system, already in June, 2005 in Hebei
inexpensive state 500kV transformer substation investment movement.
The hardware disposition is 2 Dell SC420 (Intel P4 2.8G CPU) the
server, the operating system uses SUN Solaris 10 for X86, the dispatch
system development platform is the PGC-EX2000 system. Overall
system construction cost not to conventional RISC super small machine
+ UNIX system disposition budget 20%.
The actual movement case proved that, the above solution is at
present has 优 the price compared to the middle and small scale
electric power supervisory system solution.
Uses such solution to have the following superiority:
The l system overall performance and the high end
system is same;
The l hardware price and the low end system is
same;
L uses the Unix system, the system security, the
reliability, the stability has the full guarantee;
L maintains simply. When the hardware appears
the breakdown, even if rereplaces, the expense very is also low;
The l hardware promotion is simple
L because Solaris Unix For X86 next free
will provide, might further reduce the project construction cost;
Shenzhen Si Kaida controls the technical limited company to hope
with the electrical power system user and has the strength system
integration business joint effort, rapidly promotes this system the
application, provides superiorly for the user, is better, has the
price superiority, is advantageous for the brand-new solution which
the user uses and maintains.
Appendix: SUN Corporation and Solaris 10 Unix operating
system introduction
Solaris10 soon arrives the news already let the Sun at
least excited half year. One of as Sun Corporation's souls, its
core operating system Solaris nearly load bearing Sun all innovations
makings and spiritual value, but 4 years, 500 million US dollars
research and development funds, make are regarded as by Sun Solaris10
which for a 9 years most important product renews, is bringing the
brand-new change as if to Sun. On November 15, Sun issued this
news the same day, its stock price rises immediately 4.73%, receives
Yu Meigu 5.09 US dollars. Promotes since Sun its ambitious
market capture the product plan, it in the Wall Street stock market's
performance day by day walks strongly, up to December, the stock price
has July risen since, 2004 50%. The Sun travel of revival as if
just therefore appeared the encouraging favourable turn.
Can see, Sun not only must continue its many years pursue
through Solaris10 "the subversion type" the innovation spirit,
moreover also must let such formidable technical itself leave the user
to be nearer. But Sun still needed the profit, this also was
precisely Mcnealy's pains is at: He hoped sells the Sun most
foundation with the aid of Solaris10 the product: Server,
storage device, enterprise level application software and support
service and so on. "This said regarding Sun that, is a big
gambling." Some analysts speak frankly.
But, Solaris10 brings the new characteristic or lets very many
people excited not already. Before Solaris only could move on
the Sun Unix server, now not only may move in x86 on the overhead
construction Opteron server, but also included the Nocona server, even
some sources said, Sun also could aim at IBM the Power chip and Intel
peacefully leaps the chip to promote the corresponding Solaris
edition. Therefore, Solaris10 will be allowed to move above more
widespread hardware, will include competitor Dell and Huipu's server.
But when Solaris resolutely lays down "is aloof from worldly
affairs" the figure but to even more to kiss with the posture contains
all o'clock, as if leaves the positive cycle which Sun and Mcnealy
anticipated also more and more near: Wins over the user by
Solaris in the field good oral traditions, then depends in Solaris
again the application and the technical support service earns the
profit.
Moreover, lets Solaris10 free also is Sun and even entire
operates a subtle sign to Linux which the source community splits out.
Must know that, Solaris always deeply pain of the Linux, is
precisely in IBM and Huipu Gao Duan, Linux and under the Microsoft low
end both sides converging attack, lets Sun fall into continues
murkily. Moreover the field often spreads the opening Solaris
source code pressure lets Sun be more awkward, but Solaris10 as if
will be able completely to change such condition.
Some sources said that, Sun already the Solaris transformation
was a similar opening source code project, and is establishing take
Solaris as the central programmers community, to this promotes Solaris
on the x86 overhead construction server application. Although
father of Linus Linux accepted the media interview when the little
while ago to supported x86 overhead construction Solaris/x86 to be
full is disdains: "That purely is ' the child's play '," but in
fact, Sun in issued when Solaris10, besides the technical change, the
opening source code, supports the x86 overhead construction, but also
in does not stop seeks more ISV and the SI support, even includes the
dealer.
Although is responsible for the foreign exchange Sun vice-
president AndyLark comes China when October emphasized repeatedly to
reporter that, "Sun no longer is the pure infrastructure
tenderer, after is a mature system company"; "' The network is
the computer ' the idea firmly is still grasped by us". But like
hugs Linux, forms an alliance AMD, reconciles with Microsoft, these
said regarding previously several year Sun, nearly was the matter
which not impossible to occur, but still one step by step was turned
by Sun in recently two years the reality.
"Changes the center of gravity the development based on the
AMDOpteron product, is because the massive customers gave up Solaris
and SPARC stemming from the price factor, but chose the cost to be
lower based on Opteron or the Linux server product." Has the
analyst to say like this. The worth noting is, Solaris10 plays
the free sign, the Sun business model also therefore will receive the
challenge. Regardless of borrows this to seek other links the
profit contribution, or transfers stresses the technical support and
the service, perhaps the emphasis dependence integrated system
solution creation value, the Sun front has still filled the indefinite
factor.
"I always said that, Sun and Microsoft shake hand on the picture
is two boxer in life-and-death prewar bumps touches the glove the
etiquette. To be honest, this is we now the appearance."
Mcnealy said like this in most recent several days.
