Implementation For Non-contact Maintenance Terminals Of FTU

The feeder terminal FTU of distribution network dispatching automation system is mostly installed on the column,so it is very inconvenient to patrol and maintain.With the rapid development and widespread use of wireless communication technology,it is necessary to maintain the untouchable FTU terminals in a contactless way.Based on this concept,the technical research and product design of this project complete the design of FTU contactless maintenance Terminals for the project team’s horizontal project.The project research has high practical application value..According to the task requirements of the project,the requirements are analyzed,and Bluetooth wireless communication technology is chosen as the communication means between FTU and PDA.Based on this,three aspects of technical research work have been carried out:(1)Bluetooth wireless communication technology and product implementation design;(2)Handheld PDA maintenance terminal design;(3)Mobile App as FTU maintenance terminal application software design.Firstly,the project carries out the analysis and research of Bluetooth communication technology,establishes the idea and implementation method of Bluetooth link establishment on the basis of its communication principle and protocol specification;secondly,completes the design of PDA terminal based on Bluetooth technology,including the overall design scheme,the design of terminal hardware circuit,the expansion of communication protocol between FTU and PDA and the design and implementation of terminal software;Thirdly,according to the development status of mobile phone applet software technology,using the achievements of e-commerce technology,an application software design of mobile phone App as FTU maintenance terminal is completed.Emphasis is placed on the analysis and research of mobile phone App identity authentication technology to ensure the security of mobile phone App to maintain FTU.Dynamic dual-factor identity authentication technology is selected to achieve the security control of mobile phone maintenance terminal.On this basis,the software functions on PDA terminals are transplanted on mobile phones.Finally,the maintenance terminal is validated and tested.The experimental results show that the project achieves the expected goals of technical research and product design.This project applies identity authentication technology in mobile e-commerce to FTU maintenance terminal design,and applies the development results of new technology to industrial product technology upgrading design,all of which are innovative.Throughout,there are 38 figures,10 table and 69 references.
