Abstract

This article instructs the subsequent water detection system design and implementation of sanitary ware. This system used C8051f040 Microcontroller as the main control module and communication module which controlled the operation of the entire system,touch screen as a position machine,and made use of metal probing technique and weighing sensor technology to realize data test、collection、display、storage and export. At last,the experimental results showed that this system meet the expected requirement and can measure the subsequent water more accurately. DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.4140

Abstract

High voltage circuit-breaker is an important equipment in electric system. The study on fault diagnosis of high voltage circuit-breaker would not only strengthens the security and stability of power system but also increases the economic benefit of it. Obtaining the diagnosis rules is the hardest part in building fault diagnosis expert system. This article analyses the fault samples data of high voltage circuit-breaker by rough set theory, and get diagnosis rules from it. The case shows the method is practical and feasible. DOI: http://dx.doi.org/10.11591/telkomnika.v11i1.1899
