Abstract
This system is mainly revealed the module, keyboard module, clock module, store module, communicate module, CPU module, CS5460A electric energy meter chip module and front circuit look after the part of the module to make up. The front circuit recuperates the module and adopts electric current mutual inductor and 5A/ electric current mutual inductor and accurate resistance of 2mA/2mA to realize the conversion of the city electricity, and adopt RC to strain the work and strain the wave, then adopt measure chip, CS5460 of chip, realize to electric current, voltage, measurement and conversion of electric energy by new electric energy pany, CRYSTAL of .; The clock module adopts DLS1302 clock chip to offer the clock basis for system, stores the module and adopts AT24C16, offer the data for system to store; Reveal the module uses OCMJ4X8CM liquid crystal, munication module adopts Max232 chip, and utilize CPU module that AT89S52 makes up to control the work of all chips; Measure, calculate electric energy, send to is shown the module and stores the module and pays revealing and storing in real time, send PC to location plane go on reveal and this electric energy meter have GPIB address also synchronously through standard 232 interface, so that the control over electric energy of administrative system of electric energy.
