Middle receiving thread obtains program request of data to be treated (can be described as affairs), each affairs is made of multiple steps, and
It is not identical.By the way of the step that a worker thread is handled in affairs, the operating mode of similar assembly line.
Worker thread sum is the integer of the step quantity of the sum or pending affairs of different step in all different affairs
Times.To in each transaction process, according to the difference of step, queuing is handled in each worker thread.Later, thread from
Message is obtained in safe queue, and handles message and result addition is waited for into feedback queue.Feedback thread is sent to obtain in transmit queue
Message, be sent to the embedded systems such as p l c.A task is splitted into multiple threads to realize, a thread is only run
The task step of one type so that multitask multithreading can be handled simultaneously.The case where especially for a large amount of, iterative task
Under, it ensure that per thread has task to do, without being held again using after the medium previous task execution of existing scheme
The processing mode of row next task.
Specifically, further including：The message received for each generates message, if when the one of step of thread process
Need to read the handling result of another step, then from the thread safe queues inquiry with the presence or absence of another described step
Handling result.
If then reading the handling result of another step from the thread safe queues.
If can not currently read the handling result of another step in the thread safe queues, described in processing
The thread suspension of one of step, until successfully reading the processing knot of another step from the thread safe queues
Fruit.
Wherein, thread suspension refers to：The passive saving scene of thread, partial memory are swapped out, do not access, passively open
It opens, is similar to and interrupts, while the step of thread of hang-up can continue with next message.When from the thread safe queues
After the handling result of another step is read in success, the step of thread is continued in suspended state.To each
In a transaction process, according to the difference of step, queuing is handled in each worker thread, improves the utilization rate of worker thread,
So that each worker thread is not the state in waiting so that affairs can quickly finish.Such as：In the present embodiment, each
Actual data interaction and internal communication are not present between worker thread, wherein all data interactions all pass through thread safe queues
Data in (referred to as queue) are realized, it can be understood as public data access area, such as：Affairs A needs worker thread
1,2,3, then after host process receives affairs A, while thread 1,2,3 is issued a command to, and place data into end in queue；
Following thread 1,2,3 starts to execute respectively, as thread 2 execute need thread 1 as a result, meeting when so thread 2 executes
It hangs up and handle until 1 corresponding data of thread, thread suspension rather than obstruction, so thread 2 can continue to execute other numbers
According to processing, which improves the utilization rates of execution efficiency and cpu.
For concrete example：Foreground system is issued to warehouse background system there are one order, the commodity in order need from
Certain bin level in the warehouse areas A sorts, and then needs to go to bagging area packing, finally to arrive end and sort vanning transport.We
Order is as an affairs, and after message enters wcs systems, system is just respectively added to a line to sort, being packaged, sort thread
Cheng Zuoye so that sorting has distributed packing working position while be operated in progress for it, and the thread being packaged in this way is just not
Which which need just to know pack in station after cargo sorts and completes to reach bagging area, similarly in off-sorting station into luggage
Case operates, and sometimes even can bring up which vehicle determined, the order of such a continuous productive process can reach after being decomposed
It is carried out to synchronous, greatly improves efficiency.
In currently existing scheme, solves the problems, such as high concurrent and timely respond to, it is common practice to asynchronous multiple threads
Or the mode of thread pool handles message, since operating system is to the limitation of thread-safe and thread process, such as：Between cross-thread
Data access, can be waited for by thread is influenced, and so as to cause inter-thread access exception, cross-thread transmission message is inconsistent, nothing
Method detects the problems such as Message Processing progress, the serious danger that process exception can be caused even to collapse.Cross-thread can be used on and
The mode of communication, such thread occupies memory block always to be discharged, if the task of waiting is more, for high concurrent
System requirements cpu that operating system can be caused instantaneous and EMS memory occupation it is very high, for long working system, there are poles
High security risk.Such as：In the system using the prior art, the data processing between wcs systems is in certainly by each system
Reason mechanism limitation (such as：The response time of moral agate wcs is generally in 500ms or so at present, once network oscillation occur will make
The request timed out for obtaining moment, influences the operation exception of the next system).
And in the present embodiment, for possible step having the same, but the dependence between step again may not
Identical task, can by dependence be in later step thread, inquired in thread safe queues whether have it is previous
The implementing result of the thread of step.And the step of without dependence, can directly execute.The present embodiment can be applied in plc communication
Aspect transmits/receives what thread was distinguished with worker thread.By opening up public memory headroom (thread safe queues), reduce across
Thread communication, improves the efficiency of Message Processing, also alleviates the problem of being caused in the prior art due to cross-thread communication.Such as：
By actual motion, the present embodiment can will run timeliness and be increased to the level of Millisecond so that automation equipment no longer by
To the restriction of Inter-Process Communication so that the level of second grade can only be rested on by handling the timeliness of data between system.
