Design And Implementation Of 1-Wire Bus Electronic Time Fuze Setting System

With the rapid development of science and technology, world of weapons and equipment are in further revolution, in order to meet the weapons and equipment for precision strike, end of the air defense and remote pressing demand, electronic time fuze in these areas is applied more and more widely, also requirements for electronic time fuze is also getting higher and higher.The existing wired setting mode of electronic time fuze has various wiring harness,which is not conducive to expansion and occupies large space. In view of the above problems, this paper proposed a new type of single bus electronic time fuze setting system, single bus mounted system requires only a single bus. It is used for setting the data transmission and to the electronic time fuze time installed fixed modules to provide power, and a good solution of these problems. The technology theoretical research based on the single bus technology and the electronic time fuze loading, and the single bus electronic time fuze mounted fixed system scheme design and the hardware and software of the system detailed design and concrete realization has carried on the detailed elaboration. The main content is:In depth study of single bus technology and electronic time fuze setting technique based on the proposed a new single bus electronic time fuze setting system, according to engineering development demand and empirical data related to the proposed the technical index of the system, then analyzes and designs the system composed of fixed and fuze setting module, and the setting is the main power module, main control system,keyboard and display and fuze mounted fixed module of power conversion modules,and the fuze timing module separately carried on the detailed design of the solution.2. For the single bus electronic time fuze mounted main module in the system of technical scheme and system design, system hardware circuit is designed and implemented, respectively from setting and fuze setting hardware circuit design of, to the printed circuit board design, signal integrity analysis, printed circuit board processing, procurement of components, circuit welding step by step and ultimately achieve the setting and fuze setting module, the hardware circuit of real.3. The installed fixed software keyboard input program, digital display program,setting procedure, query program and fuze software module of data storage andtransmission procedures, timing software program design and procedures for the preparation of a detailed description of and the configuration of the chip, the function modules of the software design process are discussed in this paper.4. The system hardware debugging, then analysis the system software MPLAB development platform in the debugging process, combined with the technical index of the system, testing system has been established, the setting was tested, and gives the system test results and related analysis.
