The work aims to achieve the informatization and precision of ammunition support and establish the system model of ordnance warehouse ammunition support (OWAS) based on the military Internet of Things (IOT). While the IOT technology was applied to OWAS, the basic framework of ordnance warehouse ammunition support system (OWASS) was established. An ammunition storage management platform was designed based on RFID, and a new localization and tracking system of warehouse target was established by fusing 8421 coding technology, RFID and wireless multimedia sensor networks (WMSN). Ammunition support efficiency was increased by ammunition storage management platform designed based on RFID. All warehouse targets could be located and tracked by the new localization and tracking system. Ammunition support can become visual, quick and accurate with OWASS established based on the framework of IOT. Information interaction can be realized between ordnance warehouse, personnel, equipment, ammunition and administrative department by MIOT.
