Description
(1) field
The over capacity tourist information system that the present invention is based on MP4 format technology belongs to Information application field.
(2) brief introduction
Along with the high speed development of society, improving constantly of people's living standard, and the quickening of work rhythm, tourism becomes a popular topic gradually, because its form is various, the face related to is relatively wider, becomes people's loose pressure, regulates the primary selection of mood.
The computer technology of China is born in the forties in 20th century, and starting develops very fast evening, although computing machine is introduced the field managed also just only have short 30 years, but, but bring earth-shaking change to management domain.
Popularizing with computing machine, people are also ready and are accustomed to carrying out obtaining information resource by computing machine, and people can obtain travel information within the shortest time, then draft oneself tourism scheme applicable, save the time of oneself, energy greatly, obtain body and mind to greatest extent and meet.
What traditional management method adopted is the supervisory method of people, and gone to formulate some regulations and implementation and supervision by related personnel, this can bring a lot of subjectivities to management certainly, and traditional travel information management is also management and the paper record naturally that adopt manpower.
In inquiry, be all by people's record one by one during renewal, so not only need a large amount of manpowers also to need a large amount of office appliances.This must cause the waste to man power and material, and due to workload large and loaded down with trivial details, the low of efficiency aspect will be brought, and these intangibly will make declination of profits.
Travel information service has arisen at the historic moment just in this context.The requirement of reality is that travel information managerial demand one not only can use manpower and material resources sparingly but also can save financial resources, and raises the efficiency on the basis of same equal time, thus improves whole profit.
The theory of what travel information service was taked is information classification management, system development is carried out in the specific requirement of the every aspect involved by tourism.
(3) define
Over capacity tourist information system based on MP4 format technology is with based on client/server (Client/Server, C/S) structure.
After client sends request, server can respond to its request fast and solve its request.
Which solves the waste in manpower.
Due to request and solve request process be all completed by computing machine this addresses the problem the loaded down with trivial details of manpower, also avoid some mistakes caused due to the carelessness of people of classical management approach.
Improve accuracy and the reliability of work.
The aspect designed based on the over capacity tourist information system of MP4 format technology is very wide, except can finding relevant travel information, the traffic and hotel information etc. of auspicious light can also be inquired, make to search the simple of data change, need not being immersed in a large number in the material of books and relevant photocopy, providing convenient for gathering information.
And timely in online information updating, there will not be reality and actual situation about not being inconsistent, this is also the advantage place relative to conventional management.
The aim that travel information service is designed and developed is minimizing manpower, raises the efficiency.
So, be the relevant every aspect that relates to as far as possible and travel in design, on the basis of raising the efficiency, also improve reliability and integrality like this.
The present invention is based on the specific design Application and Development of the over capacity tourist information system of MP4 format technology.
Concrete design comprises: system manager's module, travel information module, hotel information module, transportation for tour sites module, other traffic administration module, tourist service module, log off module.
The function of interpolation, deletion, amendment, inquiry is achieved in these modules.
Over capacity tourist information system based on MP4 format technology is collect, process and travel relevant activity and business information is main man/machine system.It is collected tourism data, store, processes, transmits and retrieves, and to the information that traveller and tourism staff provide, helps them to carry out decision-making or management.It has globality, the ageing and large feature of dynamic three.
1. globality.
The over capacity tourist information system Destination Management infosystem that the present invention is based on MP4 format technology is combined according to ad hoc fashion by much information element.
Along with the development of tourist industry, Destination Management infosystem has developed into the comprehensive management information system comprising food, shelter, row, the large key element of sightseeing, shopping and entertainment six.
2. relevance.
The present invention is based on each element in the over capacity tourist information system system of MP4 format technology and have specific task, thus these elements should combine according to certain rules in an orderly manner, and each ingredient has the relation connecting each other and mutually restrict.
In Destination Management infosystem, each information is all closely related with the change of out of Memory, if certain information distortion, the reliability of whole Destination Management infosystem greatly will be reduced, thus the function of each side such as the management of impair system, decision-making and consulting.
3. the present invention is based on the over capacity tourist information system dynamic of MP4 format technology.
4. the over capacity tourist information system dynamic that the present invention is based on MP4 format technology is the correlativity of refers to state and time.
5., because tourist activity is continuous change and progress, thus reflect that the travel information of tourist activity is also among continuous change and progress, this just requires that Destination Management infosystem has the characteristic of dynamic transmission.
WebGIS technology
Network geographic information system (WebGIS) is the computer system of a kind of storage in a network environment, process and analysis geography information, being the product that Intemet and WWW technology is applied to GIS exploitation, is also the best solution route realizing GIS interoperability.
User can browse the spatial data WebGIS website from the arbitrary node of Interact, make thematic map, carry out various space information retrieval and path analysis.
Therefore, WebGIS not only has major part and even whole functions of having of traditional GIS software, but also has the peculiar function utilizing Intemet advantage.Like this, user need not install GIS software on the local computer, just can access long-range GIS data and application program on Intemet, carry out GIS analysis, and provide mutual map and data.
The key feature of WebGIS is object-oriented, distributed and interoperability ' chicken roost.
Any G1S data and function are all objects, these object disposition on the different server of Internet, needs they time they are carried out assembling and integrated.
Usually, the other system on Internet can carry out exchanging and interactive operation with these objects.
The subject matter realizing the online browsing of geography information is: GIS be unable to do without figure, but current browser not support vector figure.
Therefore, realize WebGIS just needs to provide a kind of method, makes browser support vector figure.
At present, primary solutions can be divided into two classes: a class solves at client-side, and another kind of is solve at server end.
The former is by adding plug-in unit or control, in the function of client-side expansion browser, make the browser support vector figure originally not supporting figure, and supplying method and attribute changes the state of display; The latter provides related software at server end, realize the image format conversion that vector graphics is supported to web browser, then figure is sent to client display, some requests of client then meet EI (CGI) by Common Gateway or ASP (Application Service Provider, ASP) proposes.
The implementation method that the present invention is based on the over capacity tourist information system of MP4 format technology common mainly contains following several:
1.CGI (CGI (Common Gateway Interface)) mode
CGI is at browser and server and provide an interface between server and server software, plays the function served as bridge of linking up software on client and server.
Pass through CGI, client can send one to ask on server, server is given to this request the application program process of rear end again, and this application program bears results according to given request and result is returned to server, and server sends client to this result again.
More successful CGI technology has two kinds:
Batch processing graphics software and the CGI startup server form GIS software of server end is started with CGI.
The dirigibility of CGI mode is comparatively large, but program design is comparatively complicated, needs the corresponding CGI handling procedure of each program.
Because cgi script runs as independent process, thus, for the website that calling party is many, the burden of server will be very heavy, thus the efficiency of server can be very low.
2. server application interface (ServerAPI)
The method is low efficiency problem for overcoming CGI method and develops, its ultimate principle and CGI similar, but difference is:
Cgi script can isolated operation, and must run on specific server based on the program of server application interface, and thus travelling speed is faster than CGI method.
Weak point based on the program of server application interface is, it depends on specific server and computer platform.
Although server A PI and CGl enhances client (Client) interactivity, make client can obtain various geographical spatial data and map, the information passing to client remains static.
Thus, client can not operate single geographical entity and quick mitigation and amplification map, this is because be an entity at the whole map image of client, the GIS of any client operation (as amplified, reducing, mark etc.) all needs to be completed by server.
When network traffics are higher, the load of server is very heavy, and system response can be very slow.
3. insertion (PlugIn)
Insertion installs at browser end the GIS graphical information that corresponding plug-in unit is used for showing vector or the grid transmitted from server end.
This mode is transferred to the function in part of server in client, so greatly accelerates the reaction velocity of client's operation, decrease for interactive operation flow and the load of server.But insertion still has shortcoming, namely need, in client, corresponding plug-in unit or control are installed.
4.Java application program
Java is a kind of computer programming language aiming at Intemet design.
The founder of Java---the language that Java is defined as by SUN company " a kind of simple, object-oriented, distributed, indicative, Robust Security, architecture-neutral, portable, high-performance, multithreading and dynamically ", its maximum feature is once write, run everywhere, namely have nothing to do with the platform such as operating system, browser conventional at present all supports Java.
(Java Database Connectivity accessing database, also can direct access network file, has larger dirigibility, and its shortcoming is that the workload of programming is comparatively large, and speed is slower by JDBC for Java.
5. Map API
At present, on the website that some provide online internet electronic map to serve, provide map API (ApplicationProgramming Interface, application programming interface).Use map API also to develop in conjunction with AJAX technology, make developer can call resource in Online Map very easily, realize third-party application.
The present invention is based in the online internet electronic map API of over capacity tourist information system of MP4 format technology, similar to WebGIS software function greatly, but for GIS Development, the scope that both apply is different.First, transmission mode is different.
In the interactive web2.0 epoch emphasizing network, the collection of data is carried out in the mode of non-synchronous transmissions, eliminate traditional WebGIS to use in synchronous transmission technology and to accept request and the data that returns needs the puzzlement of reload page, also eliminate the uncertainty that user is awaiting a response.Typical transmission mode sends demand in the mode of queue, user receives request at server and can not operate system during back information, the operation of next stage just can be carried out after can only waiting until the request of server completing user, and AJAX application model sends the demand utilization Javascript event of client to server in client through asynchronous Javascript and XML technology, simultaneously, the information responded also also upgrades info web through Javascript through the information of, response.
Secondly, WcbGB software is generally available to professional and uses, and has multi-functional spatial analysis operation, modeling in software can be utilized when thus carrying out system development.Map API then lacks the function that sky asks analysis.
But provided map view interface oneself can meet the primary demand that general user uses for map, if so system adopts map API to develop, can be more flexible in the design of systemic-function, secondary development can also be carried out according to the demand of different user.
3rd, map API only needs application one group of key just can propose map for server asks for demand, does not need additionally to purchase software to build server, therefore with map API for system builds the bent generalized information system of W, its cost needs relative moderate.
4th, if use WdbGIS software development system, when the map information content relatively lags behind in present situation, then need the renewal carrying out cartographic information, usually upgrade cartographic information with layer substitute mode; Map supply business is then depended in the renewal of map API, and the information updating cycle of Online Map is about half a year in principle.
Therefore, for the user of secondary development, map API provides better and free update service.
