Design of monitoring microsystem used for complicated ammunitions in storage and transportation

Based on some analysis of the request of detecting complicated ammunition, this paper puts forward a monitoring microsystem composed of MEMS sensors, S3C2440 single-chip micro-controller, display/alarm unit, power supply unit, memorizer, a piece of real time clock recording chip and so on. The monitoring microsystem is designed to set in ammunition package which can provide the customer with the data to evaluate the capability of the complicated ammunition or analysis the accident. Some key problems in the microsystem design like automatic gain control circuit and power consumption are discussed, some methods to solve them are also put forward.
