Pengelog data untuk multi-meter digital_Lai Thiam Hee_E3_2005_NI
Seperti yang kita ketahui, teknologi kini membolehkan multi – meter digabungkan dengan komputer melalui port sesiri supaya dapat digunakan semasa membuat pengukuran. Komputer cuma perlu dibuka semasa pengukuran pada multi – meter dilakukan untuk merekod data ke dalam komputer. Namun, keadaan ini adalah kurang praktikal kerana ia membazirkan sumber komputer. Juga, bukan semua multi – meter mempunyai port sesiri yang terbina dalam ( built – in ). Untuk mengatasi masalah ini, projek ini dilakukan. Pengelog data yang dihasilkan dapat menjalani fungsi dan juga bebas daripada masalah – masalah yang diterangkan di atas. Semasa pengelogan data dilakukan, pengelog data dan multi – meter tidak perlu disambung ke komputer melalui port sesiri. Pengelog data bagi multi – meter digital yang dihasilkan ini dapat beroperasi secara sendiri sebagai sebuah unit ( stand-alone). Ia hanya perlu disambung ke komputer melalui port sesiri hanya apabila pengukuran telah selesai dan data yang tersimpan dalam ingatan mikro kawalan perlu disalin ke dalam komputer untuk manipulasi data secara lebih lanjut. _________________________________________________________________________________________ A normal multimeter is used to measure the voltage and current of certain circuits and also the resistance across certain lines. As the world of electronics evolves, multimeter evolved from analog to digital. But how to incoporate the data measured from a digital multimeter into a computer? The answer to the above question is the datalogger of the digital multimeter. The datalogger is connected into the digital multimeter so that the data measured can be stored into its memory. Before the era of datalogger, some latest digital multimeters have serial interface ready. By linking the interface to the computer, one can get the recording of oscilloscope for slow signals. On the downside, the computer has to be present at the measurement location, and left running all the time. Besides, the digital multimeter occupies the serial port during the entire measurement. These disadvantages certainly points to wastage of computer resources. The datalogger designed will be free of these disadvantages. It can automatically captures the discrete measurement values supplied by the digital multimeter and puts them into permanent storage. When the need arises, the contents of the datalogger will then be downloaded into computer for data manipulation.
