2) the basic control instruction of process.
The model uses optimal path algorithm, according to all defeated between beginning and end Automatic generation of information beginning and end
Line sending road on cost, energy consumption, time, line length, the strategies such as production plan, and comprehensively considers the shape of each process and equipment
State attribute, the automatic sieving sequence of implementation process.
Step 3: flow control instructions are issued to process control system by process decision system.
Flow control instructions include two kinds: one is the process initialization directives used when increasing a new technological process, a kind of
It is to the control instruction for having occupied process.
Construct general instruction format are as follows: instruction type code+command content.
Initialization directive are as follows: initialization directive type code+procedure information.
Basic control instruction are as follows: basic control instruction type code+process attribute.
Establish following basic control instruction type:
Flow startup: instruction type code 01;

After process control system receives the control instruction that step 3 is sent, process initialization directive is judged whether it is.If
Instruction is initialization directive, then whether all devices state is ready in querying flow, accounts for if any equipment fault, by other processes
With etc. unripe fault message, then will initialization failure information return to process decision system;If all devices in process
It is ready to, then initialization successful information is returned into process decision system, while establishing simultaneously initialization process executive buffer
Information.If flow control instructions described in the step 3 received are converted to correspondence for basic control instruction by instruction
Row control word, and process executive buffer is written.
Construct executive buffer

Process is converted in system instruction between each flow state.
Process is ready to: a process newly increased, and flow state is that " process is quasi- after process control system initializes successfully
It gets ready ".
In flow startup: operator clicks process start button to a ready process, and process is set from the last one
Standby to start to start, flow state is " in flow startup ".
Process flow operation: all devices all start completions in process, and without any failure, flow state is automatically converted to " stream
Cheng Yunhang ".
In process feed: under process flow operation state, feed instruction can be started to the sending of process head equipment, when first equipment
After starting feed, flow state is automatically converted to " in process feed ".
During process stops: under " process flow operation " and " in process feed " state, operator will terminate process flow operation, then point
Hit process stop button.Process can stop process according to from first equipment to the sequence of last equipment.It is wholly off complete in flow sheet equipment
Cheng Qian, flow state are " in process stopping ".After the completion of flow sheet equipment is wholly off, flow state is automatically converted to " process
It is ready to ".
Process failure: under above-mentioned any flow state, there is device fails, then flow state is automatically converted to " stream
Journey failure ".Current device failure will be simultaneously stopped the operation of upstream all devices, but not influence upstream device operation.When equipment event
After barrier is repaired, operator's pointing device failure reset, flow state can be automatically converted to " process is ready to ".
Process is stopped together: under above-mentioned any flow state, operator can issue the neat stop instruction of process, the instruction to process
For emergent stopping instruction.In process all devices can wholly off operation immediately, flow state walked around automatically as " process is stopped together ",
And the process is locked, does not allow other any operations.Release and stop state together, need operator click remove together stop by
Button, flow state revert to " process is ready to ".
Step 6: apparatus control system calls standard according to the equipment operation instruction, direction instruction and position command that receive
The single devices control function block of change realizes the fault detection and operating control of single devices itself.
Step 7: apparatus control system establishes following device status data, real for process decision system and process control system
