Design and Implementation of Human-computer Interaction Terminal Shockproof Device based on LPC2478

摘要

With the extensive use of embedded mobile terminal in everyday life, embedded terminals are getting more and more powerful, but there is no significant improvement in shock proof and use protection. The paper introduces an implementation method of embedded mobile terminal shockproof device based on LPC2478. The device has wifi communication, multi-channel sampling, real-time measurement for temperature, humidity, horizontal and vertical conditions. It measures the device distances with other objects and triaxial acceleration to achieve parametric statistical analysis and diagnostics. Its characteristics of multipoint direction identification shock proof, wireless self-synchronous firmware upgrade and power management based on users' action mode identification provide good protection for mobile terminal products, achieving the target of shockproof.
