This systematic network structure uses three-layer structure two networks form (if pursue,show 1 times) . Of the system most lower level is spot equipment (machine of industrial spot welding) , root foothold welder reachs the distance with computer room of PC monitoring software to wait in the position of the workshop, differentiate for sth resembling a net of different CAN local area network (CAN １ , CAN2, . . . , CAN ｎ ) , through CAN bus line has communication between equipment of each CAN local area network; Intermediate layer of the system is central control unit (center controller) , group control of responsible and harmonious welder is restricted to hold the job, undertake welder control, electric power is restricted look and control of balance of three-phase power power; At the same time this unit has CAN ／ Ethernet agreement to change gateway, the CAN network that can form spot equipment and go up the system undertakes a PC monitoring software change join effectively, real time monitoring runs machine of compositive spot welding system; Systematic superstratum is go up a system of PC monitoring software, the working status of equipment of spot of real time monitoring; Plant management ERP also can be passed Ethernet and go up the system undertakes a PC monitoring software data information exchange, in order to share network system information, coordinate manufacturing management. Graph agreement of communication of 1 construction of system is designed 1.

Transmission mechanism of message of CAN bus line and attemper the monitoring news that algorithm dominates node of information, monitoring according to welder system, call the police the message of failure of information, node and state information message model that builds a system, differentiate according to the important rate of relevant information the first step of the message. In CAN2.

In 0A agreement, message conveys to express and be controlled by the frame of 4 kinds of different types. They are data frame, long-range frame, wrong frame and overweighted frame, every kinds of frame is comprised by a field that differs a few times. There is arbitral field in data frame and long-range frame, arbitral field is mixed by mark accord with send remotely request a composition, among them, reasonable definition indicates accord with is very crucial. Indicate accord with is comprised by 11 binary code, express to be: D10, D9, ... D1, D0, send order to arrive by perch low. Pass pair of system integration analysis, we defined the principle of mark accord with: (1) indicate Fu Yinghan has the address that leaves an opportunity: We design issue a machine address limits to be 0~63, the work out chooses D8, D7, D6, D5, D4, D3 when mark accord with express a machine address. (2) mark accord with contains number to occupy first step: The D10 in mark accord with, D9 uses the lien that distinguishs data twice, d2, D1, D0 has different definition 3 times in data frame and long-range frame, state data, data is strung together and communication commands. 2.

On communication process the communication of unit of PC, central control and welder comes true through command mode. Communication process is: A Zhou Bo that every welder solders in electrify is given out to unit of the control central solder application signal, the spot welding machine that central control unit decides to be able to undertake soldering according to evaluating a system and the reply that is given out to allow to solder by the welder of make choice of to these, to the respondent order that was not issued to prohibit soldering by the welder of make choice of; The welder of nets of any a couplet, every are finished solder or appear when breakdown, up the PC sends data or breakdown signal directly; If did not solder newly data or breakdown, welder is interrupted temporarily with go up a PC communication. Go up a machine contain through sending the order that assigns welder address and appoint issue a machine to correspond, realize the function such as inquiry, process designing and breakdown restoration. Processing unit design is analysed through demand in the center of Nextpage knowable, central control unit needs to have the following function: 1.

Have CANopen interface, realize the group net with welder CAN network. 2.

Have aether net interface, implementation and go up a communication of data of PC high speed. 3.

Can realize CAN/Ethernet changeover. 4.

The voltage that has tall sensitivity tests device, the net presses transformer of the real time electrified wire netting that monitor. 5.

Going up a PC can move independently below the circumstance be restricted to hold control software, implementation is restricted to hold government. Pass an analysis, what we choose German BECKHOFF is embedded control system CX1000 serves as a solution. CX1000 control system is the control task that is medium dimensions and of the design, the elite of PC of its market industry and hardware PLC at an organic whole, it is one kind can be installed what go up in C slideway is modular control a system.
