power-fail detect module

The dynamic performance detecting module. This system can detect a engine accelerated speed and average power, and display the engine speed characteristic curve during detect.

动力性能测试模块：此测试仪可进行发动机加速时间、平均功率的测试，同时可显示测试时发动机的速度特性曲线。

Chapter 3 principally analyses the key problems in the design of decoder, which includes RC oscillator, POR ( Power-on Reset), Schmitt trigger, data detect module, model control logic module and data output logic module, then gate simulation is completed by Verilog_XL tool.

本文第三章设计了解码芯片的部分电路模块，包括振荡器电路、上电复位电路、施密特触发器电路、数据检测模块、型号控制逻辑模块、按键防抖动模块以及数据输出逻辑模块。

Low power consumption is important for the module to work for a long time. The microprocessor MSP430, low power consuming, is adopted to convert and detect the ECG signal.

为了使模块能够长时间工作，降低系统的功耗，中心处理单元选用低功耗芯片MSP430F149进行心电数据的采集和检测。
