Design of Auto-Detection Instrument for Airborne Thermometer System

Abstract:

To improve the test precision of detection device for some airborne thermometer system, the hardware structure and software design of auto-detection instrument for airborne temperature indicator are introduced. The 89C52 single-chip computer is used in the detection instrument. The CPU、A/D、 D/A and I/O boards are assembled as a cascade structure. By using the technology of the advanced chip and Lab Windows / CVI 5.0, the instrument’s precision and flexibility is greatly enhanced. The testing results illustrate the testing resolution is 23Bit, the output electric current is 10mA, the precision is ±0.01mV.
