Research And Application Of Test System For Power Information Acquisition Carrier Module

Power information collection can realize the real-time collection of important information such as on-line monitoring,electricity,load and voltage of metering device,and provide data support for enhancing the intensive and lean management level of the company.The timely and accurate processing of the acquisition fault is an important cornerstone of the success rate of acquisition.At present,the main reason for the success rate of the acquisition is the failure of the carrier module,which accounts for more than 65% of the failure.In the actual work,in the basic file is correct,concentrator and intelligent table communication under normal conditions,the carrier module to determine the quality of the rapid decision to become the key to fault processing speed.For the above problems,developed a portable carrier module detector.It is compatible with a variety of carrier protocols,through the analog concentrator meter reading environment can be directly,quickly and accurately determine the carrier module is normal,thus enriching the technical means of troubleshooting,in order to effectively enhance the success rate of acquisition provides a strong guarantee.Firstly,the paper introduces the function of power information acquisition and power line carrier communication technology,and analyzes the application status of carrier communication technology at home and abroad.Secondly,this paper introduces the development process of electricity consumption information collection system and the principle of electricity consumption information collection,and expatiates the low voltage power narrowband carrier from carrier modulation technology,communication channel characteristic and networking technology scheme.On the basis of the introduction of the principle,the present situation of the collection work in Baoding area is analyzed.Then,the design and implementation of the carrier module test system are described in detail,including the overall design of the system,hardware design,software design and functional design.Finally,the field test and application of the carrier module test system are introduced.
