摘要:
地面采集系统对声波变密度测井仪声波信号的识别是通过标记信号的不同来实现的,但标记信号的幅度又受到多种因素的影响。本文对声波变密度测井仪声波标记信号的产生、影响因素、处理方法等方面进行了分析,在原来仪器的基础上,找出了提高标记信号幅度的方法,以满足现有仪器生产的需要。

摘要:
数字化电源的发展,已经形成了一门综合性的学科。在现代化工农业生产、通信、电子仪器仪表、国防事业以及高新技术的装备中,高可靠性、高效率的电源,是不可缺少的设备之一。该设计采用89C2051单片机作为控制单元,利用X9241数字电位器、模/数转换器与恒流源电路部分构成数控可调的恒流电流源,系统中主要应用了数字电位器,它的输出电压作为恒流源部分的参考电压,该电压通过电压跟随器送入恒流源控制电路,从而实现恒流的输出。输出电流的给定由输入键盘来设定,89C2051通过I2C总线方式与X9241实现数据的传输。显示采用4位LED数码管,显示驱动采用软译码方式。%The digital power supply has formed a comprehensive discipline. The power supply with high reliability and high efficiency is one of the necessary equipments in the modern industry and agriculture production,communication,electronic in-strumentation,national defense and high-tech equipments. 89C2051 single chip microcomputer is used as the control unit in this design. The constant current source with numerical control and adjustability is made up by X9241 digital potentiometer,A/D converter and constant current source circuit. The system is applied mainly to the digital potentiometer. Its output voltage is taken as the reference voltage of the constant current source. The voltage is sent into constant current source control circuit through a voltage follower to achieve the constant current output. The output current is set by the keyboard. The data transmission of 89C2051 is realized by I2C bus and X9241. The four-bit LED nixie tube is adopted for display. The soft decoding mode is em-ployed for display drive.

摘要:
在当今国内工业中对尺寸的测量大多还是采用千分尺等落后的接触式的方法,不但效率不高而且精确度不高。文中讨论了线阵CCD用于尺寸测量的非常有效的非接触检测技术。本测量系统是以89C2051、TCDl206UD和ICL7135等芯片构成的,完成了由照明、成像、数据处理到显示等过程。本设计具有稳定可靠、测量精度高等特点,适用与各种高灵敏、高精度的检测。此外,本系统包括了LED显示,不仅价格便宜,而且测量结果方便可见。增加了本设计的实用性。%In the domestic industry, methods in the measuring the dimension, a contact measurement with micro meter is backward which is not only imprecise but also inefticient. The non-contact technology of Line Array CCD used in dimension measurement is very effective. This measurement system is composed of 89C2051 chip, TCD1206UD chip, and ICL7135 chip. It has finished the process of illumination, imaging, data processing and display. The design has the characteristics of dependable and precision measurement. It is suitable for various high responsive and high accuracy tests. In addition, this system including the display is not only cheap but also measurements convenient which increasing it's practical applications.
