Study On Electronic Time Fuze RF Setting Technology

Wireless setting technology is a new setting technology to accommodate the development of modern weapon, especially to accommodate the currency, succession and standardization of electronic time fuse.It has the characteristic of man-machine mutual setting more exactly,more quick setting speed and non-touching character compared with traditional setting technology. So,it makes progress quickly in recent years.This paper studys on the wireless setting technology of electronic time fuse according to the actual engineering demand.First, This paper puts forward the radio frequency setting technology of electronic time fuse.That is,first, carrier wave modulating the unmodulated information useing the wireless data transmission technology,then dispatching to receiving terminal of electronic time fuze through by wireless transmission path.At last, setting the electronic time fuse after the unmodulated information be demodulated. Realized close range non-contact setting aimed at electronic time fuse, resolved the difficult problem of multiple ammunition loading fast, duly, exactly and safe in the battlefield environment.System chooses INTEL87C52SCM as the core control device, NF2401radio frequency chip as the wireless data radiating/receiving device,PC and LED data pipe as man-machine mutual equiprnent.First, established the system model of wireless data transferring,designed the modularization system software after hardware design of the whole system. Formulated a suit of reliable communication agreement, realized point-point wireless communication of setter through programming on SCM serial portThe radio frequency setting technology of this paper aimed at electronic time fuse can achieve the desired purpose,and have a certain reference value for studying fuse setting technique.
