A data acquisition system is designed based on the datasheet of ICL7135 and EP2C5Q208C8. According to the characteristic of ICL7135, Verilog HDL language program and the software of QuartusII are used to simulate each function modules. The analysis of simulation results and experiment show that using the method of FPGA+A/D can simplify the complexity of the system design and possess a very high accuracy on the treatment effect.

In this work, a new and low-cost Arduino-Based Data Acquisition System (ABDAS) for use in an aerodynamics lab is developed. Its design is simple and reliable. The accuracy of the system has been checked by being directly compared with a commercial and high accuracy level hardware from National Instruments. Furthermore, ABDAS has been compared to the accredited calibration system in the IDR/UPM Institute, its measurements during this testing campaign being used to analyzed two different cup anemometer frequency determination procedures: counting pulses and the Fourier transform. The results indicate a more accurate transfer function of the cup anemometers when counting pulses procedure is used.

A stepper motor control system is designed based on the stepper motor controller and EP2C5Q208C8. The control system of the host human-computer interaction interface is designed by LabView; through RS232 to communicate with the PC. According to the characteristic of the stepper motor control system , Verilog HDL language program and the software of QuartusII are used to simulate each function modules. The analysis of simulation results and experiment show that using the method of FPGA+LabView can simplify the complexity of the system design and possess a very high stability on the running status. The motor running status can be easily observed in the PC interface.

An efficient data acquisition system for electronic automatic transmission test, which makes use of American NI’s data acquisition card, is designed based on Virtual Instrument. The data can be collected by the data acquisition system include automatic transmission oil pressure, solenoid duty, as well as engine speed ,turbine speed ,output shaft speed and throttle degree,and so on. The key problems of the system design are measurement method of automatic transmission solenoid duty, signal conditioning circuit design and multi-signal acquisition synchronization. Test platform is North-Benz dump truck 2627K (Its power-train assembly is replaced), of which transmission and engine use respectively HD4070PR electronic automatic transmission and BF6M1015CP electronic diesel engine. The automatic transmission shift control strategy and oil pressure characteristics of clutch or brake etc can be analyzed through test data acquisition.
