PEMBUATAN SISTEM MONITORING KWH METER SECARA TELEMETRI DENGAN PEMROGRAMAN BORLAND DELPHI 7.0

Abstract

A monitoring system based on telemetry controlled by AT89S51 has been designed and realized. This instrument can be used for household of electricity usage ( KWH metre ) by PT PLN. This system consist of hardware and software. The hardware consist of AT89S51microcontroller and RS232 protocol. The software in this system was built by Delphi 7.0 programming. This program application work serially with interfacing medium microcontroller and RS232 protocol that connected by COM1/2 on computer. The data will be send by telemetry, and verificated. Then the data can be saved in a database main computer. This system was realized and can monitoring household of electricity usage from far distance and showing in a computer. Controlling the system to work by pressing a control panel buttons on Delphi 7.0 display. The database can change by opening the edit data page and change the data.
