Research And Design Of Short-range Detector Data Logger

Data acquisition is gains the field data and the development scientific researchextremely important method. This design studied the millimeter wave short-range detectordata recording instrument skeleton and realization, involves to the millimeter waveshort-range detection system data acquisition, memory, restores, analysis and so on the keytechnologies.The paper take the millimeter wave short-range detector data recording instrument asan object, has developed the data recording instrument hardware, the system software aswell as the data analysis software research and the design on emphasis. The primaryincludes:(1) As the core completes the data recording take TMS320LF2407 DSP the hardwaresystem design. Including: Power circuit, A/D switching circuit, Flash chip connectionelectric circuit, serial communication interface circuit and so on design.(2) Completes the entire data recording instrument the system software design. Mainlyincludes: Simulated signal A/D transformation, Flash chip read and write, serialcommunication interface software design.(3) Realized the data to restore the contact surface software the design. Mainly includes: PC serial port correspondence, data document memory, curve software designs and so on.(4) Carried on the data recording instrument to the system debugs in the outfield testexperiment, real-time gathered had the project significance data.
