Abstract

Security riding is very important in the aspects of traffic. One of the main factors of traffic accidents is high speed. Therefore, it is required a speed restraint equipment for pressing the number of accidents. The car speed restraint system is available in the market, but on a motorcycle is not available yet. This paper presents a design of speed restraint equipment for motorcycle that safe for users, and is expected to reduce traffic accident. The Main idea this speed restriction is cutting off the flow of electrical signals from the pulser (the time ignition trigger sensor) to the CDI for 1 second. The cutting Signal with mechanical relays controlled by microcontroller AT89S52 using the on-off algorithm. Speed sensor use optocoupler is used to detect the number of rounds wheel motorcycle. If a result of measurement is more than the speed setpoint, microcontroler make a decission to cut motorcycle ignition signal. Results of this research is a prototype speed restraint shown that it able to process data from the measurement of the speed limit on the speed of a motorcycle. This prototype safe for all users and accordance with the set value and the level of success is above 90% for speed of 10 km/hr to 40 km/hr.

Abstract

Simulasi merupakan langkah penting dalam perencanaan. Simulink pada Matlab dapat digunakan untuk membuat simulasi sistem dengan berbagai bidang. Makalah ini membahas pengendalian kecepatan motor DC dengan menggabungkan elektronika daya sebagai pencatu, sistem elektris pada motor DC, dan sistem mekanis pada beban motor DC. Kecepatan motor DC dapat diatur menggunakan berdasarkan besar tegangan jangkarnya, yang dalam hal ini dapat dilakukan dengan penyearah terkendali. Kecepatan motor dikontrol menggunakan metode Proporsional-Integral. Hasil kontrol adalah arus referensi (Iref). Arus referensi tersebut akan dibandingkan dengan arus jangkar untuk mengatur pencatuan thyristor. Pengaturan loop tertutup ini akan menghasilkan kecepatan yang dapat dipertahankan untuk beban dinamis.
