For the remote monitoring and automation of distribution transformer,a GPRS-based real-time management system is designed,which includes terminal,master station and communication service.The SW and HW system of terminal is developed based on W77E58B of 80C51 series microprocessor and GPRS network and the centralized management and wireless remote data transmission are realized using the Delphi news mechanism.DL/T645-1997 protocol is adopted in the master-slave semiduplex data communication between terminal and multi-function energy meter,and the GPRS module of M300A is used to realize the data communication between terminal and GPRS network.The SW of management system is based on Windows platform and the real-time operational parameters of distribution transformer are acquired and processed for statistics,analysis,curves,logs and classification under the SQL-Server+Delphi environment.
