A. running status field, respectively runs, hangs up, completes, closes；
B. operating procedure field, that is, go to which step of the parallel control packet sequence；
The waiting time of c. waiting state field, including book thread and waiting state；
D. instruction field, by program control execution main thread sub-line journey is notified.
Each parallel control packet sequence sub-line journey can read the mode field of other sub-line journeys, but can only safeguard the mode field assigned by book thread；Performing main thread can read the mode field of all sub-line journeys.Instruction field is safeguarded by main thread is performed, used as the precondition of the execution step of each sub-line journey.
(A3) each parallel control packet sequence sub-line journey independence communicates with Power SCADA system, and by sequence of steps the DEC distant electric control process of corresponding series is performed, and safeguards the mode field of this thread accordingly.
(A4) actual single step DEC distant electric control process is that the order for performing, performing confirmation according to remote control selection, confirmation of returning to school, remote control is carried out, and can not be separated by certain hour between each step is performed.The timing of intervalometer sub-line journey notifies each parallel control packet sequence sub-line journey, by the waiting state field of each sub-line journey maintenance itself, if book thread is waited for, and the waiting time exceedes preset value, the step of being carrying out is abandoned immediately, continues executing with next step operation.
(A5) in general, each parallel control packet sequence sub-line journey is independent operating, but if need the state field value of another parallel control packet sequence sub-line journey as its a certain step precondition when.Conditions present is required to be put into message queue medium to be feedback by book thread, and book thread is waited to be hung up.After the precondition in message queue is fed back success, then queue is removed and for waking up the sub-line journey hung up.
(A6) intervalometer sub-line journey timing notifies program control execution main thread, and by main thread the mode field of each parallel control packet sequence sub-line journey is traveled through.After main thread monitors all packet sub-line Cheng Jun operations to be completed or be forced closed, terminate this card and perform.Flow process terminates.
B, parallel control packet sequence sub-line journey break down, and processing mode is as follows：
(B1) when a certain sub-line journey breaks down, i.e., remote control equipment operation failure when, book thread maintenance operation mode field, and terminate perform flow process, it is out of service.
(B2) when a certain sub-line journey goes to a certain step, and when needing the state field value of another sub-line journey as precondition, if as precondition sub-line journey because of failure stopping, book Thread Termination is performed, out of service.
C, by programme-control button, terminated ordering by outside router, processing mode is as follows：
(C1) it is program control to perform instruction field write positive closing instruction of the main thread to each sub-line journey after outside router terminates ordering.
(C2) each sub-line journey reads instruction field when certain single stepping is performed before remote control selection and remote control are performed, if now instruction field is positive closing instruction, then judge book thread implementation status, if current remote control is performed completed, subsequent operation is abandoned, it is out of service；If remote control selects executed, and remote control is performed and had not carried out, then after transmission remote control is countermanded an order, abandon subsequent operation, out of service.
(C3) it is program control to perform the mode field that main thread travels through each parallel control packet sequence sub-line journey.After main thread monitors all packet sub-line Cheng Jun operations to be completed or be forced closed, terminate this card and perform, flow process terminates.
3rd, interacted by internal procedure data base between node middleware and remote control middleware, each node middleware has each independent process interface area.
2nd, background service

1st, man-machine foreground message response, for processing man machine interface operation, such as remote control is performed, Action Selection, terminate etc..
2nd, man-machine foreground message feedback, for the interaction that feedback process performs real-time process and final result.
3rd, data base's interaction, selects according to man machine interface, calls the control sequence of formulation.
3rd, man machine interface and maintenance terminal
Man machine interface is served only for man-machine interaction and sends messages to background service, therefore the system is not relying on original power SCADA monitor supervision platforms, and former monitor supervision platform is simultaneously not involved in whole control flow.
4th, database structure
In order to realize programme-control, and make present system adapt to the seamless dilatation of system and reduce the modification amount of program after System Expansion.Therefore the design of remote control sequence is extremely important.Include the logical relation between each sequence additionally, due to whole control sequence, locking information etc. is all stored in data base, only need to meet demand by by safeguarding that software carries out incremental maintenance to data base after System Expansion, it is to avoid repeat the work for debugging and changing program.

1. the main table of card is constituted, structure such as accompanying drawing 1.
2. first, the parallel control packet sequence in card grouped table.The column data represents whether current card needs to carry out the remote control sequence quantity that executed in parallel is needed when parallel control and parallel control when performing.For example：" 4 " mark needs 4 remote control sequences of executed in parallel.
3. second, increase and control a point row sequence number in card step table, if card needs and control operation, the row are represented per the operating procedure sequence controlled in the lump in series.
4. the 3rd, the latching logic number in card step table is romote controlled locking sieve volume chatted above, according to this numbering corresponding to the content in latching logic table, the content is computed weighted, operation result is put in real time in message queue, and message queue is used to carry out the operation values true value matching (having true value matching list in data base).After true value is configured to, removes queue and wake up front hanging and play thread.
