Summary: Designed to be aimed at flexible production system (FMS) the computer vision system that is based on platform of sth resembling a net of local area network. This system used popular TCP/IP agreement, make different operating system platform OK each other operation, of cooperation finish flexible the visual servo task in making. Keyword: Visual system is flexible production local area network system of vision of control of 1 foreword computer is achieving subsidiary channels in the human body through which vital energy those who be based on industrial robot is flexible there is decision effect in automation production. At present robot vision basically applies at two respects: It is to give assemble a robot to provide visual facility, requirement vision system must accomplish the mechanical spare parts that can identify the place on conveyer belt to want to assemble, decide the dimensional vector of this spare parts, dominate the action of manipulator according to this information, accomplish accurate assemble. Return the inspection that can make orgnaization part with robot vision system, will unqualified spare parts identifies come out and take away. Additionally manipulator still can feedback according to the vision information, undertake soldering automatically fluctuating moving waiting. 2 it is to give portable robot to provide visual unit. Requirement vision system can identify the setting information of building site, undertake own navigation, finish critical data carry wait for the task. The task that because want to finish,2 visions system makes this visual system is more, need realizes a lot of complex algorithm. So the decision uses Tina image to handle software package. Tina software package is at present only the version that is based on UNIX/Linux platform. Effect of processing of the image below Tina environment is good, applied process is rich, the look is good to programmer interface, former code is open, it is the system that open to the outside world, undertake development and systematic function extend very easily 2 times. Be based on UNIX/Linux environment as a result of its additionally, systematic stability dependability is so good, suit to be used at industrial product line very much. And UNIX/Linux is good operation platform not only, still be very good development platform, its have the development tool with the powerful function such as Lint, Yacc, Lex, SCCS, Make, M4, to write application the program offerred good condition. Visual system basically collects module, vision to handle module, robot to control module by the vision, serve module with module of other system communication, network 5 parts form. The system is formed be based on 802 what mature most currently.

Structure of 3 aether network, this system involves operation of each other of platform of many operating systems, choose popular TCP/IP agreement part so. Function of 3 unit module and positional vision collected module to adopt WINDOWS platform, because it supports the image of most company to collect card,this is.

The Metero image that what this system chooses is the Martox firm with powerful function collects card, it can finish image to collect quantify and a few corresponding low layer computation. Use this to got stuck to reduce a vision to handle the workload of module greatly, and accord with the characteristic of distributed collateral processing that the vision handles. A catalog is founded on this machine and set to share position, in order to is deposited collect the image file that come in and had rock-bottom processing. The vision handles module to depositing Tina software package, handle the corresponding order of the work out for each phase vision, and image transmits network program, on the foundation of unit of these 3 software, developed the computer vision system that is based on X-WINDOW platform to handle environmental software, this software uses interface of visible complete Chinese, be transmitted in the network of image data and of enumerated data cross platform exchange to go up, came true the photograph is transparent to user network. This unit completes three-dimensional setting and work rebuild, identify and fixed position function, the key that is visual system is unit. Robot control module is to use labour to accuse machine, through NE2000 net 47 implement support of the people expands according to need a certain quantity of PLC is mixed odd an engine system, in order to finish flexible each processes of treatment. Network function module chooses HP workstation and people wide for familiar NT system, operate at network administrator with benefit. Workstation can be hanged as the server that print receive printer, gotten result real time print come out. Still can regard the implementation such as file server, domain name server, mail server as most network function according to need. Install corresponding software to realize pair of networks and visual system monitoring. With flexible the network interface that makes other part is unit, it is the system has expansion, as mutual as old system news report is mutual, implementation controls a network to labour, even the indispensable part of CIMS system. Because ask its have powerful network function and high reliability, use Linux system so, the file such as the Fstab that falls to catalog of Linux system Etc, Hosts, Equiv, Rhosts, Group undertakes configure and altering accordingly, make its can complete gateway and journey by and the function of firewall, if use / Usr/etc/config utility program undertakes be configuringed afresh to Linux system core, can add the equipment of a support, cut out accordingly again core, can make the system occupies memory less to improve this systematic unit efficiency. 4 visions system runs basic course this system is opposite first flexible production setting undertakes overall situation is searched, decide those who be located in a key to need treatment work next, collect a system to use double camera to collect image by image come in, collect in image undertake rock-bottom image is handled in the system, conduct gotten result to visual processing system, visual processing system undertakes matching rebuilding waiting for the job, in order to restore the three-dimensional and stereo appearance of workpiece, can match with the appearance unit of the model library that is based on CAD, obtained the name of workpiece and treatment information. Send message to the computer to control a system next namely the control module of visual servo. This can control robot and corresponding PLC unit, will finish flexible production treatment process. Other module is auxiliary function, for instance network module can print a workpiece CAD blueprint, with flexible the network interface part that makes other part can is opposite flexible production system has expansion, with other network or the workstation interconnection that are used at CAD/CAM/CAPP, can increase greatly flexible the function of production system. OK still other and as flexible as administrative network production network interconnection, make the one part of CIMS system. The is based on aether network computer vision system that article place designs 5 conclusion, in actual flexible get applied in production system, because this system was used 802 general.

3 agreements and popular operating system platform, make the construction cost of visual system is reduced greatly, and used UNIX system make dependability rises, the vision handles what the function used popularity to be based on a network collateral processing technique, improved efficiency. In software write and considered adequately on systematic design but expanding, the system is patulous very convenient. This system can be in all sorts of flexible the application in production system and CIMS, have certain versatility. CNC Milling CNC Machining
