基于MEMS加速度计的倒置开关
Design of an inversion switch based on MEMS accelerometer
摘要
Abstract
An inversion switch for internal electronic pressure gauges was designed by using MEMS accelerometer MMA8453Q and MSP430 MCU.Thereby,using the direction detection function of the accelerometer,MCU reads its acceleration through the Ⅰ2C interface and judges whether the tested device is inversed.For the designed inversion switch,many inverse tests were carried out by the stepping motor and the success probability was 100％,and the impact resistance was tested by adopting a Hopkinson bar system.The results show that the inversion switch can still work after the impact of 45 000g.So the designed inversion switch can be applied on high-g impact occasions.关键词
