The Capacitive Proximity Fuze System Research And Design

In the recent years, the technique of capacitance proximity fuze has developed rapidly. Capacitance proximity fuze has applied successfully to mortar, howitzer, rocket and completed the aopinion of design one after another. So, it's very important to research capacitance proximity fuze.This paper researched the main systems of capacitance proximity fuze including detector, signal processor and simulation-testing system. The design of the simulation-testing system is an emphasis in this paper. The paper reseached the specific method of designing the simulation-testing system and designed the simulation-testing system of fuze based on MPU technique. The simulation-testing system tests mainly the detonate time of fuze and adjusts the parameter of fuze. The paper focuses on the design of the simulation-testing system, then the project of the simulation-testing system, the flow chart and finctions in each modules was introduced detailedly. Last, the whole flow chart of the simulation-testing system was designed from dowm to upon.Besides, the reseach of acquisition-electrode is anther emphasis in the paper. This paper analyzes and describes the design-methed of acquisition-electrode detailedly. points out general principles we should notice as designing.
