Problems solved by technology

To reflect the local drawing situation in other terminals in a timely manner, it can be simulated by transmitting mouse and keyboard messages to remote terminals, but this method will cause a large amount of data transmission, and the effective data transmission efficiency is low. If the transmission of graph

Abstract

This invention relates to computer supporting coordinating work (CSCW) technology field, especially belongs to the new coordinating application environment of coordinating geographic information system, the communication, the architecture and the coordinating medicine. The device of this invention is composed of plot input and output, the processor, the coordinating processor and the internet. This invention solves the problem of coordinating plot of multi-users in the internet environment and it is completed by plot and edit; through the data communication of user terminal and server terminal adopt compressing and encrypting methods, and form a picture target sheet before the plot conclusion and send it out, and realize the response speed and data safety of the system. The advantages are maintaining the coherence of the user terminal video through conflict detection and operation switch, ensuring the response speed and data safety of the system, and also has high-relative response, highly efficient data transmission, good coordination and safety.

Description

technical field [0001] The present invention relates to the technical field of computer-supported collaborative work (CSCW), in particular to a new collaborative application environment for collaborative geographic information systems, collaborative traffic, collaborative buildings and collaborative medicine, etc., for use in the Internet environment An Internet-based collaborative drawing device and a collaborative drawing method for multi-user collaborative drawing of graphics. Background technique [0002] The wide application of CSCW (Computer Supported Cooperative Work) in conference systems, geographic information systems, transportation, construction and medicine has produced new technologies such as remote electronic conference systems, collaborative geographic information systems, collaborative transportation, collaborative buildings, and collaborative medicine. collaborative application environment. These application environments all need to draw graphics collabor...
