Description
Technical field
The present invention relates to power informations to acquire communications protocol technical field, is a kind of transparent task agreement of master station protocol support
The method and system of extension.
Background technique
Along with the raising of expanding economy and living standards of the people, the power consumption in life production rapidly increases, and gives
Power network safety operation brings bigger test.As Utilities Electric Co.'s accessing user's quantity is increased sharply, it is based on remote reading system
System, new business are continued to bring out in various regions.Instantly main website-acquisition terminal communications protocol belongs to service-oriented type agreement, that is,
Agreement is formulated for the specific business of each Utilities Electric Co., once the business occurred except agreement cannot be according to existing task flow
Cheng Zhihang.In this case, mainly using concentrator as terminal execute transparent transmission, realize indirectly according to this main website with
The direct interaction of electric energy meter.But existing communications channel imperfect stability, lead to the mission failure rate under such mode
It is 20% to 30%.
Summary of the invention
The present invention provides the method and systems that a kind of master station protocol supports transparent task protocol extension, overcome above-mentioned existing
There is the deficiency of technology, caused by existing transmission channel is unstable when can effectively solve existing implementation power information new business
Communication timeout, the high problem of mission failure rate.
Technical solution of the present invention first is that being realized by following measures: a kind of master station protocol supports transparent task association
The method for discussing extension, it is characterised in that the following steps are included:
The first step is arranged task and defines, and in transparent task, newly-increased data cell is arranged and identifies Fn and measurement point Pn,
Enter second step later；
Second step, query task execute state, identify the execution shape that Fn defines transparent task by newly-increased data cell
State enters third step later；
Third step, task report, and report to the implementing result of transparent task.
Here is the further optimization and/or improvements to invention technology described above scheme:
Above-mentioned the data cell mark Fn is stored in corresponding different application layer function code AFN in the first step, is answered
It include that 1 class data of request, 3 class data of request and data forwarding, the 1 class data are with the corresponding message of layer function code AFN
Real time data, the 3 class data are event data.
It is above-mentioned in the first step, the application level function code AFN is encoded using hexadecimal.
It is above-mentioned in the first step, the described newly-increased corresponding message of data cell mark Fn includes as AFN=10H
Remove transparent task F305, the transparent task F306 of setting and the transparent task F307 of inquiry, the transparent task execution as AFN=OCH
State F305 and transparent task action result F306, the transparent task action result ERC64 event as AFN=OEH.
It is above-mentioned in second step, the execution state of transparent task includes that identity authentication result, event is waited to report and inquire
Whether non-reporting measurement point is had.
Technical solution of the present invention second is that being 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, the acquisition terminal pass through extension
Communication link receives the request message of system main website transmission, communicates to connect between measurement point and acquisition terminal, the request disappears
Breath includes request change electric energy meter authentication effective time, request adjustment electricity price and request acquisition electricity price.
Above-mentioned acquisition terminal can be concentrator.
Above-mentioned measurement point can be electric energy meter.
Only authentication is unconfined etc. this avoids task there are validity period in entire transparent flow of task by the present invention
To, also unified the timeout threshold of whole system, avoid different route time-out time it is different and caused by trouble.Different electricity
Energy table issues task using priority policy, does not influence daily acquisition and transparent electricity price issues task and take turns may be implemented more
Electricity price is successfully issued to all electric energy meters for meeting authentication by secondary execution.Extended Protocol of the invention be suitable for it is all with
The remote task that transparent mission mode executes, the direct initiator of the remote task are concentrator, will be between main website and electric energy meter
Interaction is converted into asynchronous by synchronizing, and improves communication efficiency, reduces main website holding time, effectively increases the success of task transmission
Rate.
