Research And Implementation Of Power Production Information Platform Based On HTML5

The power supply management of the oil field requires the power maintenance personnel to check whether the equipment information such as the switch,changing table and other equipment is in accordance with the original circuit diagram and modify the equipment information in real time to be stored in the database,deal with the faults in the inspection process according to the safety standardization process and record,upload audio files.According to the actual situation of the site,it is necessary to develop a multi-platform application management system combining mobile terminal and PC terminal.Based on the above requirements,this dissertation focuses on the rendering of web route map and the recording and playback of webpage audio,and finally uses HTML5 technology to develop the power production information platform,realizing "one development,running everywhere".This dissertation develops a Web application for both PC side and mobile device maintenance management,proposes a new method of web development based on HTML5 new technology,on the basis of studying the existing web technology,which makes up for the shortage of traditional web development relying on plug-ins.Firstly,this dissertation uses the DXF format file of Auto CAD as the data source of route drawing.Study the core drawing technology of Canvas,design and implement the circuit diagram interaction event,Study the method of design of internal element event response.In view of the problem,Study the method of design of internal element event response.At the same time,In order to improve the rendering efficiency,a hierarchical drawing architecture is proposed.By using object oriented thinking to encapsulate the Canvas API twice,the basic drawing of the circuit diagram is realized.secondly,research the recording and playback of web audio,realize Audio recording and playback by using the Audio API combined with Web RTC technology.At the same time,In order to meet the needs of network real-time transmission,the principle and technology of web audio compression are deeply studied,and the audio recording and playback method suitable for network transmission is realized.Finally,by studying the above key technologies and combining with the actual needs of Oil field electric power production,the development and application of power production information Platform is designed and completed,which has theoretical and practical significance.
