Reset circuit so that it is in normal power supply and clock time to do so have a signal, all the motherboard does the reset signal is sent to the South, then we look at the reduction and whether it is normal, one can test the related equipment to test the reset point, to see if it has an instant change of the voltage jump, the second is to look at testing the reset card instant flash of light, under normal circumstances, it is the flash, if that does not shine or Always represent abnormal.

复位电路呢，它是在供电和时钟正常的时候呢产生的一个信号，主板上的所有这个复位信号呢，都是由南桥发出来的，那么咱们看这个复位是否正常，一是呢测这个相关设备的这个复位测试点，看它是否有瞬间的电压跳变，二是看测试卡上的复位灯瞬间闪一下的，正常情况下呢，是闪一下，如果说是常亮或不亮都代表不正常。

After power is ON, a central processing unit reads a register value stored in the UIM card detached/attached history detecting unit through a peripheral circuit.

开机后，CPU通过外围电路读取存储在该检测单元中的寄存器值。

The RC loop parallel with the card formed an electric circuit on the series relay coil to excite the coil and make the contact maloperate.Therefor,it is suggested that a resistor or a capacitor be connected with the relay in parallel to lower the exciting voltage at both ends of the output relay.

经过分析研究，我们找到了有效的解决方法，消除了事故隐患。1 问题的提出DCS生产厂家提供的开关量输出卡为了保护数据输出回路，往往在输出接点两端并联一阻容回路，如图1的C1和R1。

In this thesis, an all-digital phase-locked loop with large multiplication factor is presented. This circuit can be applied to the video system as a clock generator. It receives the horizontal synchronous signal from the graphics card and then generates a high frequency pixel clock according to the monitor resolution setting to acquire the video signal data. The stability of this sampling clock affects the display image quality directly. If the pixel clock is not stable, the display image will be glittering or jittering.

在本论文中，我们提出一个高频率倍数的全数位式锁相回路，此电路可应用於视讯系统中的时脉产生器，其主要功能是接收显示卡发出的水平同步讯号，并依据使用者设定的萤幕解析度，产生高频像素时脉来撷取视讯讯号资料，取样点的稳定度直接影响到显示画面的品质，若是像素时脉不稳定，则显示画面会闪烁或抖动。

Abstracts: To sample high speed random signals without drop, a design of O-shaped high speed random signals acquisition card based on the CPLD and its realization are presented. It consists of same three sets of acquisitive circuits, which construct O-shaped structure to sample the signals without drop .And it adopts threshold judging method to determine the valid data in the process of the acquisition, abandons vast of the redundant useless data at the same time, it only sends the useful data to the host computer by the way of DMA, so it is easy to processing the data. The design is concise and reliable. The sketch map of the logic circuit and the explanation of the main parts are presented. This design has been applied in the engineering project of sampling α nuclide.

为了对随机到来的信号进行不丢失的高速采集，提出了一种基于CPLD的随机信号环形高速采集卡的设计与实现；通过采用三套采集电路形成一个环形结构，可以对随机到来的信号进行不遗漏的高速采集，而且在采集过程中利用阈值的方法鉴别出有用信号，并舍弃了大量的冗余无用数据，从而只将有用数据以DMA的方式传于主机，便于进行信号的处理；电路设计简洁可靠，并给出了主要的逻辑电路示意图与主要部件说明；该系统已经应用在采集α核素的工程实践中。
