Microcomputer-Based Data Acquisition System for Engine Performance Test
초록
This study was carried out to develop a microcomputer-based data acquisition system for engine performance test. A low-cost data acquisition system was developed utilizing an "APPLE II PLUS" microcomputer. The developed system consists of microcomputer, RPM counter included frequency-to-voltage converter, preamplifier for two load cells and 8-bit analog-to-digital converter with 16 chnnels. The system simultaneously measures engine speed by means of photointerrupter, torque and fuel consumption by means of load cells with variable sample numbers, sampling intervals and repetitions. The system collects, processes and provides data for storing on the
