Description: 针对非固定的电动机转速测量问题进行探讨。电动机采用在轴端或轴面粘贴反光纸的方法，每转一周可产生一个脉冲，我们将检测每个脉冲的周期通过微处理器倍频后变成占空比为50％的标准方波信号，这样不仅大大提高了脉冲信号的稳定性，而且其检测精度可由倍频器的倍频倍数来决定。而本文主要是对脉冲信号的倍频精度与稳定度进行控制.-For non-fixed motor speed measurement to explore the issue. Motor used in the shaft end or axial paste method of reflective paper, each week to produce a pulse, we will detect each pulse cycle, through the microprocessor after the octave into a 50 duty cycle for the standard square-wave signal not only greatly improve the stability of the pulse signal, and the detection accuracy by multiplier multiplier multiplier to decide. And this paper is the octave pulse signal precision and stability control.

A total of seven modules of the project: week control circuit, the date of the control circuit, control circuit of the month, year, control circuit, select the month of the circuit, scan display circuit and regulating circuit. The general idea is: the date a week and share a pulse control circuit signal date back to the binary-conditioning circuit, and then by adjusting the switch control circuit to choose the month and the month of the pulse signal control circuit, at any time to play a role in regulation of the month with the rationale for, the month of binary control circuit to adjust the feedback circuit to adjust the year at any time.

Description: QPSK是一种二维调制技术，其中水平轴称为同相轴，垂直轴称为正交轴，分别对应于星座图上的1和Q坐标。同相载波指载波本身，正交载波指相位旋转90度的载波1周。QPSK调制在实现时是采用正交调幅的方式，某星座点在1坐标上的投影去调制同相载波的幅度，在Q坐标上的投影去调制正交载波的幅度，然后将两个调幅信号相加就是所需的调相信号-QPSK is one kind of two-dimensional modulating technology, the horizontal axis is called the alignment, the vertical axis is called the normal axis, corresponds separately in the star map 1 and the Q coordinate. The synchronism carrier refers to the carrier itself, the orthogonal carrier refers to the phase rotation 90 degree carrier 1 week. QPSK modulation when realization is uses the orthogonal amplitude modulation the way, some constellation in 1 coordinate s projection demodulate synchronism carrier s scope, in the Q coordinate s projection demodulate orthogonal carrier s scope, then two amplititude-modulated signal adding together is the phase-modulated wave which needs
