OEC microcomputer controller in low-yielding oil field application


Arbitrarily set according to site conditions. 4) can override the well smooth start, swing,[link widoczny dla zalogowanych], and the number of swings can be arbitrarily set according to the scene. 5) Industrial Mini printer can print at any time convenient to the well within one month of data and advice at the history of the accident point. 6) self-repair. Memory modules use the United States Xi-cot's non-volatile components and continuous real-time calendar /, day-inch bell, from power outages, wind up effects such as accidents, even after power-on work. Excellent data from the power-down protection to keep the system clock together with the completion of self-repair in case of accidents. 7) has the watchdog monitoring. Watchdog monitoring module independent of the central processing unit, frequency of 50 times per second to establish contact with the CPU,[link widoczny dla zalogowanych], can handle any situation of crash failures, thus further improving the system of self-repair. The premise does not change any wiring, you can easily work for manual and automatic. 4.2 Features 1) scrape together monitor the whole structure, the installation is simple and convenient. 2) the system safe and reliable operation. The input AC power supply module. i. . t. . . . i. . . . . . . . ~. . . . . . . . . . . . . :. . . . 2. . . 0. . . . 0. . . . 5. . . . . . . .

In the automatic control condition, motor oil and motor protection with a microcomputer integrated electronic protection of double protection,[link widoczny dla zalogowanych], avoid motor damage due to abnormal phenomenon. 4) The anti-interference ability. By the software and hardware of many anti-jamming system to enable the machine to adapt to the scene bad work environment. 5) The energy saving effect. Can not change the pumping function of the original premise of the control of the low-yielding wells for energy-saving technological transformation, its comprehensive energy-saving rate can reach 30%, thus greatly improving system efficiency of pumping wells and reduce consumption of oil wells . The microcomputer controller in low-yield oil wells installed on-site application of 95 CPC units. After more than three years of field application results show that the superior performance of the controller has good energy saving effect, the average saving rate of 32% comprehensive. Its application,[link widoczny dla zalogowanych], as well Gudong oil to further enhance the management level and economic efficiency of enterprises play a good role in promoting. Reverse Engineering three-dimensional optical measurement system in the mold design and manufacture of the Soviet Union sent Geng Lei Niu dawn (Heilongjiang Institute of Mechanical Engineering, Harbin 150027) Abstract This paper introduces a three-dimensional optical measurement system principles, characteristics, measurement methods and applications , which combines the use of digital image processing technology, photogrammetry and raster measurement technology, rapid and accurate measurement of three-dimensional physical surface of the mold design and manufacturing to provide a quick method. Keywords ATOS scanner; photogrammetry; grating measurement; die 0 Introduction in the mold design and manufacturing, sometimes three-dimensional measurement by laser scanning or physical structure of optical measurements to get the kind of data and input to the computer for processing, according to the measurement data to establish the number of real three-dimensional CAD model. ATOS three-dimensional optical scanning system is used in measurement and grating projection measurement method of a combination of three-dimensional measurement technology, is a non-contact measurement method, with accurate and fast access to data characteristics, in the mold design and manufacturing will play an increasingly important role. 1rOS three-dimensional optical measuring system ATOS 1.1 Principles and characteristics of three-dimensional optical scanner is a fast digital camera-based optical measurement system, the middle of an ordinary light source, at both ends of a CCD camera (see Figure 1), which uses photogrammetry, grating measurement two methods to measure physical, using digital image processing technology, access to real three-dimensional CAI) digital to analog. Photogrammetry is a good digital camera has been placed on the reference point and reference marker in the physical order from a different perspective (at intervals of about 45.),[link widoczny dla zalogowanych], The azimuth of the kind to take photographs. Taken from two different angles salt banana:! Digital images, obtained by image processing identification code 5 or more of the same reference point as two coordinates of the relevant image, and then use photogrammetry theory, the two images as the reference point in the code to determine the coordinates of the camera 2 shot of a space transformation to obtain a known coordinate system. According to the topological relationships which are fitted with different images in a non-coded reference point. So after multiple digital images can be obtained for all non-coded reference point in the same space coordinate system coordinates. Figure 1ATOS three-dimensional optical scanner 37 *
