Description
Technical field
The invention belongs to the power system automation technology field, relate to WEB diplopia technology in the power automation supervisory control system.
Background technology
Traditional diplopia system adopts C/S model (being the client end/server end pattern) more, needs the special client-side program of installing, and a little less than the distributed function, can't realize rapid deployment, and poor compatibility.Although common Web diplopia system has adopted B/S pattern (Browser/Server Mode), but be difficult to satisfy refreshing of real time information, mode commonly used is after client is regularly initiated a request, server returns and comprises result and relevant extra content, need refreshing of full page, the network bandwidth that takies can be larger, is difficult to realize in the WEB service so that real time information is upgraded.Solution commonly used is Development of ActiveX Control, the renewal of contents processing, and shortcoming is could realize service function behind the client downloads control, does not satisfy " thin " client's requirement.Mostly watch circle is to adopt drawing instrument directly to draw SVG figure, loaded down with trivial details and complicated, can't satisfy the requirement of flexible picture group.
Summary of the invention
For overcoming the above-mentioned problems in the prior art, the invention discloses a kind of SCADA WEB diplopia technology that is applied to the power automatic system field.This invention generates SCADA supervision graph technology automatically based on the electric power assembly template of SVG, and carry out data access in conjunction with RIA and GSOAP, Comet technology, adopt JSON exchanges data form, watch circle is dynamically played up in real time, realized SCADA system WEB real time monitoring function, embodied being modeled as the figure integrative ideal, also guaranteed the high efficient and reliable of network and transfer of data, access, carried out the informix operation by watch circle pel integrated data integrated technique.
The present invention specifically by the following technical solutions.
A kind ofly it is characterized in that based on the Power SCADA WEB mode Real Time Monitoring diplopia method of scalable vector graphics SVG in conjunction with rich internet RIA, said method comprising the steps of:
(1) electric power assembly template automatic mapping: service end is utilized the electric power assembly template, generate the electric power pel, described electric power pel comprises simple pel and the combination pixel that is comprised of simple graph unit, the watch circle that meets " based on the common graphics exchange form of SVG " standard of State Grid Corporation of China's formulation by the electric power primitive generating, and monitoring figure is published to the WEB server, carry out the information issue by the WEB technology;
(2) based on long Comet and the JSON data interchange format of connecting, required real time data is schemed in monitoring be transferred to browser client from server: the real-time Data Transmission technology based on Comet and JSON, in the mode of Comet technology as transfer of data, adopt JSON lightweight data interaction form, so that described real-time stream reverses, be after server end finds have described real time data to upgrade, the real time data that needs are upgraded " pushes away " browser client, wherein, described real time data information comprises that switching variable, topology play up data;
(3) described watch circle is dynamically played up in real time: browser client shows required real time data information by obtaining the watch circle page with server interaction, find the watch circle corresponding assembly by the assembly ID in the real time data, described watch circle is dynamically played up in real time, and in conjunction with document object model DOM technology the watch circle of dynamically playing up is in real time carried out real-time release;
(4) at the WEB server end described watch circle pel being carried out the integrated data information integral processes, use the RIA technology by rich internet integrated data information is carried out the information issue, wherein integrated data information comprises real time data, primitive attribute, object properties, the information such as history curve, historical data.The present invention has following beneficial effect:
The present invention adopts the B/S pattern, has the distributivity characteristics, and professional expansion is simple, easy to maintenance.The present invention is in conjunction with RIA and Comet technology, displayed page is not only in the effect of client computer in RIA, it can calculate asynchronously in backstage and user request, transmission and retrieve data, integrated user interface and Integrated using sound and the image of demonstration, and does not rely on and other controls.Aspect Refresh Data, carry out the generation of service end data by compilation tool GSOAP, adopt JSON packed data mode transfer of data, improved efficient in Data Update, saved the network bandwidth.By template automatic mapping technology, can scheme by the required SVG of dynamic generating system, reduced complexity, increased flexibility.

Fig. 4 the present invention is based on SVG in conjunction with the flow chart of the Power SCADA WEB diplopia method of RIA.
Embodiment
Below in conjunction with Figure of description technical scheme of the present invention is described in further details.
Disclosed by the inventionly may further comprise the steps in conjunction with the Power SCADA WEB diplopia method of RIA based on SVG, as shown in Figure 4:
Step 1: based on electric power assembly template automatic mapping technology
As shown in Figure 1, service end generates pel (Fig. 2 is the electric power graphical element model) by the electric power assembly template, and pel adds power information, comprises graphic attribute, device attribute information, annexation attribute, also comprise in addition the definition of figure metaevent, operational approach, as shown in the table.One secondary electric power monitoring figure can be comprised of a plurality of electric power pels, can adjust flexibly the formation of electric power pel.By this specific character, electric power monitoring figure can combine the electric power template flexibly.
By the SVG watch circle of electric power primitive information automatic mapping technology generation standard, as follows:
The SVG watch circle that generates carries out the information issue by the WEB server.
Step 2: based on the power real-time data transmission technology of Comet and JSON.
In the power real-time data transmission technology based on Comet and JSON, with the foundation stone of Comet technology as transfer of data, in conjunction with electric power CIM model and JSON data format the efficiency of transmission of power real-time data is greatly improved.This mode is so that data flow is reversed.Service end " pushes away " client to data after finding have data to upgrade.Avoid so the useless network bandwidth to take.The data format of transmission carries out the tissue of JSON form according to power model, has reached a balance in size of data and the network bandwidth, has optimized network and has improved efficient.
Step 3: the in real time dynamic Rendering of watch circle.
Watch circle is dynamically played up in conjunction with DMO technology (document object model) by real time data, be divided into the three phases process: obtain the real time data stage, assembly is searched the stage, and assembly is played up the stage.
Obtain data phase: by getting access to real time data with server interaction;
Assembly is searched the stage: find the watch circle corresponding assembly by the assembly ID in the real time data;
Assembly is played up the stage: the watch circle assembly is played up;
Step 4: watch circle pel integrated data is integrated
As shown in Figure 3, at the browser server end described watch circle pel is carried out integrated data (real time data, primitive attribute, object properties, the information such as history curve, historical data) integrated treatment operates integrated data information: use the RIA technology by rich internet integrated data information is carried out the information issue.
Simplified operating process by pel integrated data integrated technique, clear and definite primitive information function reaches the ability that informix is processed.
