Objective The traditional technique was not suitable for information collection of ammunition storage transportation shelter. There was a need for a system to automatically identify ammunition information. Methods The article finally chose Radio Frequency Identification(RFID) to gather ammunition information automatically through comparison with the existing identification technique, based on the demanded functions. The article studied the technical parameters of electronic tag and reading writer devices of RFID system and put forward some requirements and functions of the software in RFID system, based on the demanded functions, characteristics of ammunition and advantages of RFID. Results The article ascertained the technical parameters of electronic tag and reading writer devices, and the software demand of module construction and function realization. Conclusion The application of RFID system facilitated the automatic identification of the ammunition information, automatic gathering and management of the in-out warehouse information, and convenient management of the stock ammunition.
