The Design Of Grenade Onboard Image Reconnaissance System Based On DSP

Image reconnaissance system is the core of the internal circuit components of theimage reconnaissance grenade, which is used into battlefield scene image intelligencereconnaissance. The battlefield scene image is transmitted to the soldiers or the rearcommand center by wireless, which is convenient our battlefield deraignment. This articlemainly researches the onboard image reconnaissance system, completed the design of thesystem hardware and software driver development. Make the system feasibility test andsystem comprehensive analysis. The main results of this paper are:According to functional requirements of the onboard image reconnaissance system,make a detailed whole system scheme and work flow. In the aspect of hardware, throughthe modular method, the system hardware circuit includes the CMOS image acquisitionmodule, DSP central processing module, 2.4GHz ISM wireless transmitter module andUSB-NRF24L01wireless receiver module.The CMOS digital acquisition module achievesthe image collection and the high-speed image data cache.The digital signal processorTMS320F23885 complete the image compress. At last through the 2.4GHzISM wirelesstransmitter module and USB-NRF24L01wireless receiver module. Achieve the data wilesstransfer, and then the image data uploaded to the host PC to decompress, display and store.In order to complete the hardware function，make a detailed software design anddebug.ystem completing the system modules pin functional initialization configuration andchip work parameters configuration of OV7670 and NRF24L01.The whole system designcomplete the function of image acquisition and wireless transmission.At last, the system experiment verifies the reliability of system hardware circuit anddesign of software, meet the requirement of onboard image reconnaissance systems, and canproceed to the next step of circuit production.
