The paper proposes a method of design and implementation of anti-shock human-machine interactive device based on LPC2478. The anti-shock device has WiFi communication capabilities, multi-channel sampling, and real-time measurement for temperature, humidity, horizontal and vertical conditions. It measures the device distances with other objects and drops acceleration to achieve parametric statistical analysis and diagnostics. Meanwhile, the device has several function features: it has multi-direction anti-shock sensors, self-synchronizing wireless firmware upgrade functions, power management based on user pattern recognition, which meets the protection requirements for portable terminals.%介绍一种基于LPC2478的嵌入式人机互动终端抗震装置的设计与实现.该终端抗震装置具有WiFi无线通信功能,能够多路采集,实时测量现场环境中的温度、湿度,以及设备水平垂直情况,与其他物体的距离及下降加速度,实现参数统计分析与诊断,监督报警的功能.同时,装置具备多点方向识别抗震、终端无线多点自同步固件升级、基于用户动作模式识别的电源管理等特点,满足了对移动终端的保护要求.
