| This paper proposes the use of automatic remote meter reading meter readinginstead of the traditional disadvantages arising. Based on the data collectedautomatically compare the meter reading communication system and analyze theadvantages and disadvantages of the various methods, and then based on its ownsupply network in Tianjin Port, the proposed coexistence of two communication dataacquisition program.First, the system is based on three remote port area communications network as aplatform to each variable, substation RTU equipment for the terminal, relying on threeremote data processing system to perform remote meter reading system automationfunctions. Which use RS485connection bus communication interface to solve theproblem of energy meter with RTU interface can not be directly connected. Andthrough the RTU compiler implements the data read and upload feature.Second, it is based on the GPRS network communication technology powerremote meter reading system. In the initial design principles of reduced investment,take a way through the firewall server directly connected to the Internet. Proven overtime, this approach proved by the large outside influence, and easier to receive hackers.To solve this problem, we propose the use of dedicated lanes to move the company toapply for a way to improve the stability of data transmission reliability. And compilethe corresponding program allows meter reading terminal device through the "new645" Statute metric information will be uploaded to a dedicated power wirelessnetworks, and then through a dedicated wireless network communications server to thepower company remote meter reading system server.The latter part of this article to set the system back to the software functions aredescribed, and the signal debugging process prone to interruption, data transmissionand other issues raised can not be a solution, similar to the system for the future appearin actual use questions provide a reliable basis. |
