Title The Development of a Real-time Power Measurement System for Fuze Circuits
Abstract
With the enrichment of functions and the enhancement of performance for fuzes, the requirements of performance for fuzes are increasing. Micropower is therefore an important development trend of modern electric fuzes. Obtaining the accurate dynamic power consumption data of fuze circuits, which is of great importance for improving circuit design and optimizing the match of battery performance.
The purpose of this project is to design a real-time power measurement system which includes a hardware circuit based on C8051F410 microcontroller used to measure the supply voltage and current consumption of fuze circuits and a software written by VB used to achieve the calculation of power and dynamic display of measurement data. During the process of design, a joint software simulation debugging for microcontroller and PC software programs is implemented. Finally, the ultimate product of this system is also debugged by experiments whose result shows that the measurement error can be controlled within 5% or less at low power consumption state and the entire power measurement system has relatively excellent practicality and stability.
