Description
Technical field
The present invention relates to power information and gather communications protocol technical field, be that a kind of master station protocol supports transparent task agreement
The method and system of extension.
Background technology
Along with expanding economy and the raising of living standards of the people, the power consumption during life produces rapidly increases, and gives
Power network safety operation brings bigger test.Along with Utilities Electric Co.'s access customer number amount is increased sharply, based on remote reading system
System, new business continues to bring out in various places.Instantly main website-acquisition terminal communications protocol belongs to service-oriented type agreement, namely
Formulate agreement for the concrete business of each Utilities Electric Co., once occur that the business outside agreement can not be according to existing task flow
Cheng Zhihang.In this case, mainly concentrator is performed transparent transmission as terminal, the most indirectly achieve main website with
The direct interaction of electric energy meter.But existing communications channel imperfect stability, causes the mission failure rate under this kind of pattern
Be 20% to 30%.
Summary of the invention
The invention provides a kind of master station protocol and support the method and system of transparent task protocol extension, overcome above-mentioned existing
Having the deficiency of technology, the transmission channel instability existed when it can effectively solve existing enforcement power information new business causes
Communication overtime, the problem that mission failure rate is high.
One of technical scheme is realized by following measures: a kind of master station protocol supports transparent task association
The method of view extension, it is characterised in that comprise the following steps:
The first step, arranges definition to task, in transparent task, arranges newly-increased data cell mark Fn and measures some Pn, afterwards
Enter second step；
Second step, query task performs state, is defined the execution state of transparent task by newly-increased data cell mark Fn, it
Rear entrance the 3rd step；
3rd step, task reports, and reports the execution result of transparent task.
Further optimization and/or improvements to foregoing invention technical scheme are presented herein below:
Above-mentioned in the first step, described data cell mark Fn leaves in corresponding different application layer function code AFN, application layer
Message corresponding to function code AFN includes asking 1 class data, asking 3 class data and data to forward, and 1 described class data are real-time
Data, 3 described class data are event data.
Above-mentioned in the first step, described application level function code AFN uses hexadecimal to encode.
Above-mentioned in the first step, described newly-increased message corresponding for data cell mark Fn includes as AFN=10H
Remove transparent task F305, transparent task F306 is set and inquires about transparent task F307, the transparent tasks carrying as AFN=OCH
State F305 and transparent task action result F306, the transparent task action result ERC64 event as AFN=OEH.
Above-mentioned in second step, the execution state of transparent task includes waiting identity authentication result, reporting events and inquiry
Whether there is non-reporting measurement point.
The two of technical scheme are realized by following measures: a kind of master station protocol supports transparent task
Protocol extension system, including system main website, acquisition terminal, measurement point and communication link, described acquisition terminal is by extension
Communication link accepts the request message that system main website sends, and measures and communicates to connect between point and acquisition terminal, and described request disappears
Breath includes that the request change effective duration of electric energy meter authentication, request adjust electricity price and request gathers electricity price.
Above-mentioned acquisition terminal can be concentrator.
Above-mentioned measurement point can be electric energy meter.
There is effect duration in the present invention only authentication in whole transparent flow of task, it is unconfined etc. that this avoids task
Treat, also unified the timeout threshold of whole system, it is to avoid different route time-out times is different and the trouble that causes.Different electricity
The task that issues of energy table uses priority policy, does not affect daily collection and transparent electricity price issues task and can realize taking turns more
Secondary execution, is successfully issued to all electric energy meters meeting authentication by electricity price.The Extended Protocol of the present invention be applicable to all with
The remote task that transparent mission mode performs, the direct initiator of this remote task is concentrator, by between main website and electric energy meter
It is converted into by synchronization asynchronous alternately, improves communication efficiency, reduce main website holding time, be effectively increased the success that task sends
Rate.
