In the 1950s, the economically developed countries in the construction of large modern cities in the high-rise building, in order to increase and improve the use of architectural features and service, first proposed building automation requirements, the contents in housing construction there are various instruments, and control devices and signal display , and other equipment, using centralized control, surveillance, and to facilitate the operation and maintenance of operational management. Therefore, these facilities are required to place an independent transmission line will be dispersed in the construction of equipment connected to form their own independent centralized monitoring system, which is commonly referred to as professional circuit wiring system. As a result of these basic systems using artificial manual or automatic control mode preliminary, a lower level of technology, equipment and the necessary equipment wide variety and complexity, many of the number of lines, the average length of long, will not only increase the project cost, but also not conducive to the construction and maintenance.
20 since the 1980s, with the continuous development of science and technology, especially communications, computer network, control and graphics technology integration and development and high-rise housing construction services and the increase of objective requirements of the conventional professional cloth line system is already able to meet the needs. To this end, developed countries have started studied and introduced comprehensive cabling system, and the 20th century the late 1980s integrated wiring system and gradually introduce China. In recent years China's national economy has maintained rapid development, urban high-rise building in the various new public buildings and the completion of modernization, especially as the information society is one of the symbols in the Intelligent Building Integrated Cabling System has become the modernization construction hot topic, but also in the construction and communication engineering design and construction of a very important integration of the content.
At present, the application of intelligent building in the most comprehensive cabling system is D algorithm will be able to meet users simple, basic requirements, but, with the intelligent building intelligent degree requirements increase, the traditional cabling system because of its algorithm restrictions to meet with the current complex needs of users, then find a more reasonable, more optimized, flexible strong, good stability and scalability of the new algorithm to meet user demand for increasingly complex has become an urgent task.
Through investigation and study found that, based on the ant colony algorithm is a robust population of stronger algorithm, nature has many excellent for solving complex combinatorial optimization problems provide a new train of thought. Its main features are: positive feedback, distributed computing [4]. A heuristic algorithm with the combination of positive feedback process makes the method can quickly discovered a better solution; Parallel Distributed easy to achieve, combined with the heuristic algorithm, making this method easy to find better solutions Furthermore, the title is a partial TSP, and ant colony algorithm to smaller time complexity price for TSP, therefore, the combination of user needs in this paper, using ant colony algorithm to solve the integrated intelligent building wiring problems, the results proved that, based on the ant colony algorithm integrated Cabling System, the complex will not only meet the needs of users, while the results for the better, and time complexity greatly reduced, for the design and construction personnel saved a lot of time, while also lowering the cost. Therefore, based on the ant colony algorithm to achieve the integrated wiring system is of important significance, but also further enhance the level of intelligent building intelligent.
In the life, some constructions flaunted its intellectualized degreeachieves 5A, even are more, in fact is the automated system thinresult.
But synthesizes the wiring in the intellectualized construction is thehigh speed information network physical foundation, constructs one ofin intellectualized construction essential links, therefore thesynthesis wiring designs the personnel to have to act according to thenetwork the characteristic, the line cable performance, the systemtotal investment synthesis plan design.
The comprehensive wiring is refers in a building or in thearchitectural complex through the electric cable, the optical fiber,each kind of soft cable as well as the correlation connects theintelligence transmission medium system which the hardwareconstitutes, it and continues each kind of transmission medium theequipment to compose according to the certain order an organic whole,supports such as the pronunciation, the data and the picture and themonitoring management information transmission and so on theapplication [ 2 ]. It does not like traditional the wiring - each weakelectricity system from the adult department, is mutually irrelevant,for the construction, the maintenance brings many difficulties. Ituses the standard the correspondence medium and 连接跳线themethod, may act according to the demand the change, jumps the linethrough the wiring system, the realization function nimble adjustment.It uses the open style modular design, also is easy to connect theexisting different type the equipment, also for the future new system,the new equipment will meet the person to provide the possibility. Theunification, the advanced transmission medium and the standardconnection structure for the system installment, the debugging, themaintenance provides the convenience, simultaneously has guaranteedsynthesis wiring 先进性 and the reliability.
The traditional comprehensive wiring system are many take D (Dijkstra)the algorithm as the foundation realization, caused it not to be ableto meet modern customer many need, thereupon, this article proposedone kind newly based on the ant group algorithm comprehensive wiringsystem
The ant group algorithm was one kind which recently several years onlythen proposed new draws up the ecosystem algorithm, seeks through thesimulation ant group from the ant's nest solves the most superiorwiring way to food most short-path process, by Italian person and soon scholar M.Dorigo, V.Maniezzo, A.Colorini first proposed, they callit the ant group system (Ant Colony System - ACS) [ 3 ].
Discovered according to the biological modelling scientist's long-termresearch that, The ant although does not have the vision, whenmovement can release one kind of special secretion - informationelement in the way (Pheromone). When when they bump into the streetintersection which has not passed through, stochastically chooses away vanguard, simultaneously can release with the way length relatedinformation element, the ant walks the way long, then releases theinformation element quantity is smaller. When the afterwards antbumped into this street intersection once more time, the readoutelement quantity bigger way probability could relative be bigger,like this has formed a regeneration mechanism. In the most superiorway information element quantity is more and more big, but in otherways the information element quantity actually can pass along with thetime reduces, finally the entire ant group can discover the mostsuperior way. Moreover the ant also can adapt to circumstances orenvironment change, when in the ant group movement way suddenlyappears the obstacle, the ant also can very quickly refind the mostsuperior way. Obviously in entire seeks in the diameter process,although the single ant's ability to select is limited, but enable theentire ant group through the information element function the behaviorto have extremely high from the organization sense, between the ant isexchanging the routing information, finally discovers the mostsuperior way through the ant group collective from the catalyzedbehavior.
Question supplement that, Declines the direct software translation,how also has slightly to organize all of a sudden, ha-ha
In 1984, in the world the first intelligence mansion was born in the United States to admire the blessing virtuous city especially, it is led by an old financial mansion to reform into the information technique but become of, and in the mansion rent rate, investment the recovery rate, economic performance etc. obtain success[5].Caused the value of all countries and imitate later on, intelligence the building gets a quick development within the scope of world.In the intelligence mansion once develop the reason, the United States has been ising placed in world to lead level.In recent years, in the United States lately set up and change set up of the office building, 80% is so-called intelligence type of.According to the estimate, up to the present already more than 10,000, such as IBM, AT & T company headquarters mansion etc..
The American intelligence constructs think factory to construct the definition to the intelligence for:Pass to the structure, system, service of the building and manage the superior combination of[with] four basic factors and their inside contact to provide an investment reasonable, and then have efficiently, comfort, convenience of environment.
Japan starts constucting an intelligence mansion in 1985, having already been close to 70% for the intelligence type in the lately- set up mansion.The characteristics is the construction that the big business enterprise turns a mansion to the intelligence is very hot liver, in the meantime, the Japanese government also pushes actively, drawing up four development programmings of layers, namely intelligence city, the intelligence building, intelligence family and intelligence equipments, but along with the emergence of the Japanese bubble economy, the Japanese intelligence constructs of development speed and file time be influenced by severity.
The development of nation intelligence in Europe building basically starts synchronously with Japan, intelligence mansion mainly concentrated in the modern city of all countries.The intelligence mansion of the Pacific Asia region then is main to concentrate in Seoul, Hong Kong etc. center city.Singapore government throws in a huge sum, programing to set up Singapore"intelligence city garden".Because of the influence of[with] economic crisis in Asia, the development of intelligence building in Southeast Asia is subjected to influence.
The our country intelligence building begins from 80 expect with the beginning of 90's after years, once sent a person to Switzerland in 1991 ability the virtuous company carry on a technique training and study to unite with that company then in the domestic to expand building an automation(BAS) later on[6].
The our country begins from 90's in last century to the research of intelligence building, 1990, set up in Peking of Peking develop a mansion it may be said our country intelligence building of embryonic form, after again set up Shanghai museum, gold in Shanghai luxuriant mansion etc.1 have equal intelligence the large and public building of the level.But, currently the intelligence mansion of our country regardless from construction standard still from construction quality aspect and foreign advanced level compare, returning can be regarded as a "quasi-" intelligence mansion.According to relevant data statistics, our country have already set up of the intelligence building have 70% to circulate above falsely often, real attain an intelligence building standard of is number not much, result in in the meantime of investing and wasting the phenomenon is astonishing.The nation established intelligence a building expert's committee after hasing already discovered this circumstance, entering upon to draw up to rule concerning standard and design, to intelligence building system integration the company carry on natural intelligence to approve officially a work.
The intelligence constructs the inest the last few years in the our country develop very quickly, many public facilitieses, the key figures construct, even the residence small areas all request intelligence to turn, intelligence building heat will arrival or already arrival.In the meantime, our country government to intelligence building the development gave to support actively.In 1995, the Chinese engineering construction standardized association to release 《building and buildings synthesize the design norm of the cloth line system engineering 》[7], at the same year, "intelligence building design standard" in Shanghai releases.In 1997, the construction department released 《the building intelligence turn a system engineering's design to manage temporary provision 》.In 2001, the construction department releases 《the intelligence building design lead 》, further norm the our country intelligence construct a market.Some provinces, cities also did an aggressive work in the aspects, such as relevant technique, norm of the intelligence building and policy...etc..Shanghai, Peking, Sichuan, Liaoning...etc. establish the professional committee of the intelligence building and academic think factory successively.
Is the concrete body of national comprehensive national strength and technique level now, its characteristics and advantage obvious, domestic and international the market thinks ° to be good very.The intelligence building not only needs to be in line with international information superhighway, but also wills also promotes the development of information superhighway furthers.The development of intelligence building will arouse on criticizing related technique and the development of industry, such as the information, electronics, automation, calculator, electric power technique etc..Intelligence building at domestic and international of development on the up, foreground vast, the international community studies and develops an intelligence building a technique competitively.
