Abstract: With the rapid development of information construction, the project design to rely on traditional video conferencing, conference calls, e-mail between joint trials cannot meet the needs of people to communicate. This article describes the presentation of this new technology of remote visualization for plan approval system and operating practices fully comply with the approval needs of the design process in the drawings, the real feasible project design industry's high-tech plan approval mode, give water conservancy the design of communication of the design industry to bring new changes.
Key words: Remote Visualization for Plan Approval; System; Project Design
1 Introduction
In general, it is necessary for the flow of the water conservancy project design to undergo six major stages (discussion on plan demonstration on plan drawing design discussion on drawing reviewing drawing examination and verification on drawing). In the whole design process, the largest trouble is the process in which a large amount of communication and discussion are necessary. In the process, there is not only the communication between different designers, between designer and general project leader, or between design institute and project owner, but also the communication between local and remote places [1].
After the 1990s, along with the popularization of computer, telephone and Internet, the frequency of business trips is reduced to some extent. In the meantime, however, along with the rapid development of economy, the engineering industry has attained a swift development and expansion, and increasingly more, large and complex projects undertaking heavy tasks unceasingly emerge. Therefore, a great amount of communication is needed much more. In addition, the needs of people on communication can't be satisfied by the traditional video conference, call conference, and email, etc.
2 Remote Visualization System for Plan Approval
Because most communications about the water conservancy project designs are carried out by the personnel together in the form of holding a conference, they mainly rely on a white board or PC and projector. However, the disadvantages of this way are (1) the participants in the conference can't directly write, amend and annotate the drawings on the projection curtains, making the description not enough intuitive; (2) annotation and punctuation can't be realized, the participants in the conference need a note for recording amendments suggestion, and therefore the information can't be recorded in time and also they can't actively participate in communication and exchange, etc.
However, the large electronic board and drawing reviewing system are skillfully and creatively combined together by the remote visualization system for plan approval, and thus an intuitive, practical and easy solution is provided for a great number of project designers. Besides, the user terminal is a mobile terminal, in which the large-size white board, audio and video system and drawing sharing software are integrated together. Mobile design can be easily promoted in a conference room in which no professional equipments are available, and therefore local conference and internet accessing can be realized with the insertion of power line. That is, the remote conferences can be realized [1].
With the remote visualization system for plan approval, the traditional plan approval model in the project design industry is changed, the communication cost becomes lower, the errors of design personnel are reduced, and energy consumption is saved. Therefore, the remote visualization system for plan approval accords with the concept of the low-carbon environmental protection in the modern times.
3 Application of the Remote Visualization System for Plan Approval
The advantages for the water conservancy project design industry to apply the remote visualization system for plan approval can be concluded as follows: (1) the remote visualization system can be greatly used in the local discussions; (2) large-amplitude drawings can be rapidly shown, and thus the printing of the undecided manuscripts of drawings can be abandoned; (3) plan writing and showing can be shown directly, including the labeling, modification and saving of office documents and CAD drawings, etc; (4) all above work can be quickly completed if necessary to have a remote communication.
3.1 Local Plan Approval
This can be used in a large number of local discussions. Through a large and touchable electronic board, large-amplitude drawings can be rapidly shown. Therefore, the printing of the drawings can be abandoned. In the meantime, plan writing on board, plan demonstration, CAD drawings labeling and modification can also be realized, etc [2]. Also, a powerful drawing presentation system can be available, and simultaneously multiple drawings and white boards can be opened. This is very important for the smooth communications.
3.2 Remote Joint Plan Approval
When it is necessary to make use of a remote communication, all the work can be quickly completed with the same methods. The working personnel in the remote place can complete the work synchronously through the system, like discussing the real drawings in a conference room. The shared drawings are stored in the sharing end, and also it is unnecessary for the participants in the remote end to acquire the real drawing files. Therefore, not only the needs on communication can be satisfied, but also the outflow of the drawing files can be efficiently controlled and prevented.
In addition, with the remote visualization system for plan approval, the communication functions of the remote video conferences can be implemented, and simultaneously the collaborative browsing and labeling, remote joint plan approval and remote joint plan verification can be shared.
3.3 Management of Plan Approval Records
In the remote visualization system for plan approval, the drawing amending records can be saved according to the usernames and labeling time of the conference's participants signing in the system, and all amendments suggestions can be inquired according to persons [4]. If the name of a relevant person is clicked, the amendment and handwriting records of the person will be immediately flashing on the drawing, and therefore the traceability is realized.
3.4 Freehand Plan Approval
A function is developed for displaying the traditional hand-drawn images in the system through an entity drawing platform. This provides a great easy-to-use feature for the engineers who have used to using an entity drawing. The drawings can be labeled randomly with water pencils through laminating as long as the drawings are moved on the exhibition stand, but the original drawings won't be altered [1].
Especially, it is very troublesome to re-make the electronic versions for some early design drawings. However, this difficulty can be solved with an entity platform. Certainly, the images of entity drawings can also be displayed on the displayer with their electronic versions, and thus the plan approval comparison, design drawing modification and other functions can be realized [5].
3.5 Remote Video Conference
Video conference is the most fundamental application of this system. It is very practical for the daily work and discussion. In the meantime, the cost is low. Therefore, it has been extensively applied in all kinds of meetings.
3.6 Collaboratively-designed Plan Approval
By relying on the remote visualization system for plan approval, work flow and data flow can be processed with high efficiency; the coordinative working among multiple departments in the enterprises can be realized; the interaction between enterprise internal processes and inter-enterprise office processes is supported. Therefore, the collaborative working in an enterprise or different enterprise can be realized in a real sense.
3.7 In-depth Integration with Project Management Software
In the remote visualization system for plan approval, the on-site monitoring can be directly called according to projects, and also is integrated with relevant businesses. If a hidden trouble for security can be found, the rectification and reform notice can be directly called, and also the images captured in the monitoring process can be automatically saved by the system as an attachment in the letter of notice.
4 Advantages of the Remote Visualization System for Plan Approval
Because people are allowed to randomly write and input something with hands in the remote visualization system for plan approval, images and figures can be inserted and also can be freely zoomed for the sake of easy explanation; multiple new white boards can be established at the same time, and also the teaching contents on the white board can be repeatedly browsed; the tools of hardware electronic white boards as well as all sorts of functions can be easily called. All personnel are allowed to write on the white board and images and interactively learn. All these are the advantages of the remote visualization system for plan approval. Therefore, the following functions can be realized.
4.1 Unimpeded Data Sharing
Users can share the commonly-used files formats such as PPT, Word, Excel and PDF, are allowed to write and draw diagrams and curves on the white board provided in the system, and also can share the multimedia files for an aided teaching. In the meantime, a more perfect interaction can be provided for the users. Therefore, users can share their desktops and applications, and also can transfer the control privileges to conference's participants for a remote control [6].
The sharing of desktops and applications makes the professional programs such as CAD, 3D graphics software and professional management software shared as well [7] and also the remote control and technical support realized. Therefore, it becomes a convenient tool.
4.2 Saving and Track of All Communication Data
In the process of sharing white board, documents and programs, the shared and collaboratively-shared labels and modifications of each participant in the conference can be saved with two ways (i.e. recoding in conference and saving label records). Compared with the conference system only providing a recording function, a track way, which is more convenient, intuitional and easier to find, needs to be realized [8]. All video and audio records as well as data in the communication process can be saved and traced.
4.3 Integration with PSTN and GSM Networks
PSTN and GSM telephone conference accesses are realized in a creative way. If a conference is held in the system and also a person out of the conference needs to be contacted, the telephone number of the person can be directly dialed in the system and he will access to the conference for communication. Similarly, under the state of no internet access conditions, the participants can take part in the conference through the traditional PSTN telephone system and even a mobile phone and have an exchange with the participants in other places [1].
4.4 Giving Consideration to Conference Room Application and Desktop Application
In the system, a full consideration is given to conference room application and desktop application. Therefore, the leaders can realize mobile official business and emergency commanding by using notebooks and internet when having a business trip, and also can hold the conferences through mobile phone and land line when there is an emergency. In the meantime, the working personnel can carry out remote conference, business consultation, training, work negotiation, etc [9].
4.5 Integration with the On-site Monitoring System
The system can be integrated with video monitoring system, promoting the users to not only receives reports in the conference when using it, but also get a clear understanding of the current progress of project.
In addition, the access of project construction site monitoring video to the conference is supported. Therefore, construction site can be very intuitively shown to the personnel participating in the communication through the comparative presentation of drawing and on-site practices. This is very useful for efficiently solving the design problems, which are encountered in the construction.
4.6 Integration with the Instant Communication Products
Many forms of development API are provided in the system, and can facilitate the video conference system to integrate with other applications and programs. The perfect combination of conference system with instant communication system can promote the staff in a group to exchange and communicate at any time and place. Therefore, business can conveniently develop.
4.7 Integration with the Information Products of the Third Parties
On an "information islet", the timely sharing and feedback of information can't be realized, and therefore the smooth development of business is affected. The primary problem in "information islet" is that information can’t be timely and sufficiently shared, and thus the information share can’t be realized efficiently between systems, affecting the smooth development of business. However, the remote system for plan approval is installed with a standard and open interface, which is compatible with Windows/Linux platform and can be seamlessly integrated with large-screen system, third party’s OA system, and project management system. The problem in information islet can be prevented in the construction process of the information system to the maximum.
4.8 Individualized Customization and Development
An open components structure is applied in the remote visualization system for plan approval. All functional modules (including terminal and server) can communicate through a uniform messaging bus mechanism. Also, customization is available according to the actual needs of the end users. Project management can be achieved as long as API interface in development kits can be secondarily developed.
5 Conclusion
The remote visualization system for plan approval has a function supporting the access of the monitoring video on construction site to the scene of conference. Therefore, construction site can be very intuitively shown to the personnel participating in the communication through the comparative presentation of drawing and on-site practices. This is very useful for efficiently solving the design problems, which are encountered in the construction. More importantly, however, its presentation and operation habits can completely accord with the needs of real drawings approvals. Therefore, the remote visualization system can really become a feasible plan approval model in the water conservancy project design industry.
