PEMBUATAN PROGRAM PADA SISTEM TELEMETRI MULTISTASIUN KETINGGIAN PERMUKAAN AIR MENGGUNAKAN GELOMBANG ULTRASONIK DENGAN BORLAND DELPHI 7.0

Abstract

Have been done a program making at system of multistation telemetry of level water height use the ultrasonic wave by Borland Delphi 7.0. system of data Delivery pursuant to principle FSK ( Frequency Shift Keying). This Peripheral applicable to various need for example monitoring of level water height for the distribution of PLTA, system of forewarning tsunami and others. Monitoring of long distance of multistation conducted by microcontroller at center station presented to computer with the program of Borland Delphi 7.0 accepting data from station of object A and B. ultrasonic Wave will measure the distance of level water height and processed by microcontroler at the object station. Later, Then the station will deliver the data continually to microcontroler receiver at station center in the form of data in set of centimeter (cm) and data will be presented to computer of pursuant to comand from computer. At this system data accepted by a computer of processed into set of metre ( m) and made as yardstick of level of level water height able to arranged the level and keeping in the form of bases of data Ms. Acces. Data Bases yielded covering of height data irrigate in two set of centimeter and metre, date of and depository moment time and also height status. From research done to be got result of measurement from two station. Result of examination that height of object measurement equal to read result at computer.
