Description
Technical field
The present invention relates to a kind of remote signalling processing method.
Background technology
Remote signalling is a critical function of distribution power automation terminal, can obtain distribution switch deciliter state, switch pressure state, vacuum state, blocking, cabinet door state etc. by remote signaling function.The remote signalling displacement event that remote signalling displacement produces is the important evidence of assistant analysis distribution line anomalous event.Therefore remote signaling function is one of critical function for distribution network automated terminal.
The remote signalling processing mode that present distribution automation terminal is conventional under embedded real-time multi-task operating system, cannot carry out the remote signalling process that many remote signalling loop (more than 24 loops) keeps high-resolution function simultaneously.Present distribution automation terminal remote signalling process generally makes with the following methods:
1) single inquiry mode, interrupt mode process remote signalling data.Although the method can reach multiloop, high-resolution requirement, task is single, and set expandability is not strong.
2) not with in the application of embedded OS, use and interrupt obtaining remote signalling displacement, by main program process remote signalling event.Although the method can reach multiloop, high-resolution requirement, task is single, and set expandability is not strong.
3) in embedded OS, the mode process remote signalling of job enquiry is used.Although this mode solves the process embedding remote signalling in style multiple task operating system, the requirement on high-resolution road cannot be solved.
Summary of the invention
The object of this invention is to provide under one can be implemented in embedded real-time operating system and complete the high-resolution remote signalling processing method of multiloop.

Embodiment
The present invention mainly describes under a kind of method can be implemented in embedded real-time operating system and completes the high-resolution remote signalling process in loop.The present invention mainly comprises three steps:
Step one, remote signalling state obtains, and adds remote signalling state queue.
Step 2, process remote signalling state queue, generates remote signalling event, and is added to remote signalling event queue.
Step 3, process remote signalling event queue, completes remote signalling reporting events.
Above-mentioned three steps are linked together by remote signalling state queue and two queues of remote signalling event queue by the present invention.The present invention uses remote signalling state queue: the displacement of remote signalling state scans in interruption, and remote signalling Bitwise and time enter remote signalling state queue; Use remote signalling event queue: remote signalling event, by the scanning of remote signalling state queue, produces, is incorporated to remote signalling event queue in task.
Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 1, first obtain remote signalling state, and the remote signalling state of acquisition is added to remote signalling state queue; Its concrete steps comprise:
(1) clocked external interrupts producing, and enters external break events process;
(2) in the middle of outside interrupt processing process, status scan is carried out to remote signalling port, detect all remote signalling port statuss;
(3) if corresponding remote signalling port and last corresponding remote signalling state of interrupting preserving inconsistent, then illustrate that this remote signalling port conjugates, all remote signalling port statuss added markers, and then these remote signalling port statuss are added to remote signalling state queue; Record epicycle remote signalling port status, this state is used as the reference contrast foundation of lower whorl remote signalling port status simultaneously.Epicycle remote signalling TCP terminates;
If corresponding remote signalling port and last time interrupt the corresponding remote signalling state consistency preserved, then illustrate that remote signalling port conjugates.Epicycle remote signalling TCP terminates.
As shown in Figure 2, then process remote signalling state queue, generate remote signalling event, and remote signalling event is added remote signalling event queue; Its concrete steps comprise:
(1) system call, enters the process of remote signalling task;
(2) whether detect remote signalling state queue is empty;
(3) if remote signalling state queue is not empty, then process remote signalling state queue, generate remote signalling event, and the remote signalling event of generation is added to remote signalling event queue; Waiting system scheduler task is hung up;
If remote signalling state queue is empty, then waiting system scheduler task is hung up.
As shown in Figure 3, finally process remote signalling event queue, complete remote signalling reporting events; Its concrete steps comprise:
(1) system call, enters remote signalling reporting events Processing tasks;
(2) whether detect remote signalling event queue is empty;
(3) if remote signalling event queue is not empty, then remote signalling event will be reported; Waiting system scheduler task is hung up;
If remote signalling event queue is empty, then waiting system scheduler task is hung up.
As shown in Figure 4, in distribution automation terminal control module, use embedded real-time operating system.The task such as external interrupt task, sampling calculation task, data calculation task, log task, upgrading task, maintenance task, communication task, remote signalling Processing tasks is run in system.External interrupt triggers with every 100us, the acquisition of remote signalling state is carried out in external interrupt, arbitrary remote signalling state changes, and all remote signalling states are joined remote signalling state queue, the sampling on multichannel remote signalling (more than 24 tunnels) can be realized, ensure that remote signalling markers precision can in ± 100us simultaneously, owing to only needing remote signalling IO to scan and process of joining the team, remote signalling does not take the external interrupt process function too many time in this part process, surveys this holding time and is only 2.24us.
In remote signalling Processing tasks, whether be empty, if be not sky, all remote signalling state queues gone out team and is processed into remote signalling event queue if detecting remote signalling state queue.Owing to having had the accurate markers of remote signalling and remote signalling state in remote signalling state queue, therefore remote signalling event handling can have been carried out in the task that real-time is so not high.
Use embedded real-time operating system, can conveniently expand other tasks, the remote signalling state that requirement of real-time is very high obtains and the acquisition of remote signalling markers completes in a fast manner in interruption, can not cause the loss of remote signalling information.The function of remote signalling event handling realizes in task, therefore also facilitates other tasks of system extension.
Below be only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvement without departing from the principles of the present invention and polishing, should be considered as protection scope of the present invention.
