Study on the Temperature and Speed Test System
A kind of multiple parameter data acquisition system was designed based on single-chip microcomputer which can realized the data acquisition of temperature and DC motor speed. The data acquisition system consists of sensor, signal processing circuit, single-chip microcomputer and LED digital tube. The speed signal is acquired by photoelectric sensor, put into the Single-chip microcomputer processed after processed by signal processing circuit, and displayed the value in the digital tubes. The temperature signal is acquired by digital sensor, and the Single-chip microcomputer can read the data directly. Through two independent keyboards, the test system realized the data acquisition and data switch displaying of the multiple parameters.
