Components connected with microcontroller and the corresponding module in the microcontroller under software control, to complete the measurement, display, print and alarm functions. UU * 35.0 leaf showing the major components of each point is the temperature of online instruction; the keyboard can be achieved through human-machine dialogue, such as online changes, and set the parameters (mainly temperature setting more limits); alarm components to bee Buzzer sounds for monitoring the temperature of the measuring point, the temperature of the more limited point that appears to give tips to staff to make the appropriate treatment; the same time period required for the various points of a temperature devices can also be printed report output. 2. Software design in the system modular design, a variety of different functions by separate subroutines. Subroutine compiled modules: display module, the key processing module, A / D converter module, the print module, alarm module L3J (program omitted). Third, the temperature calibration process 1. Since] I590L is a current element, Kelvin output, the nominal value of 1, that is, each degree of increase in current increases 1K l. In the 4051 series switch circuit in a 10kQ resistance to the current one into 10mV / K voltage, in order to reduce measurement error, the resistance of resistors in parallel in order to obtain accurate 10kQ. 2. Celsius Kelvin subject of a conversion, the figure for the voltage follower A1. Output of 0.01V / K, which is a ground voltage; A2 is an inverting amplifier, it will base diode voltage amplification circuit RP multi-turn potentiometer to fine tune the AD590L time in the 0 ~ C The output voltage is 2.73V, so that both A1 and A2 is the output voltage between 0. 01V / C, and realizes the subject's ~ Celsius temperature conversion. IV Conclusion The system design is simple, stable performance, high accuracy, able to carry out various functions of microcontroller programming and flexible configuration and modification. Medium-sized enterprises in particular the production process for multi-point temperature of the circuit in the measurement and monitoring. References [1] Ding Zhensheng.

Beijing: Beijing Aerospace University Press, 1990, three-dimensional non-contact measurement system of human research about the first Zhangwu Ming Peng Ronghua Zhong (Department of Mechanical Engineering, Tsinghua University, Beijing 100084, China) Abstract In this paper, without contact with the body size of three-dimensional measurement system was introduced, discusses the basic principles of human body measurements, the system structure and splicing programs, and the physical measurements of human experimental model. Experiments show that the system is easy to operate, high speed and measurement accuracy advantages. Key words Computer vision non-contact measurement of a three-dimensional mosaic body measurement, the introduction of human three-dimensional scanning system in fashion design, human morphology, multimedia animation have a wide range of applications. And the human body in many areas related to the body three-dimensional scanning system can provide three-dimensional human body data entered into the computer, customers will be able to effect the data processing and interactive applications. If combined with advanced manufacturing techniques such as rapid prototyping and reverse engineering, you can sculpture, artifacts and other areas play an important role in reproduction. It is compared with the traditional measurement methods, with measurement speed, non-contact, easy to automate and so on. Second, the basic principle of Figure 1 is a three-dimensional non-contact measurement system schematic, projection device 36 * to have some characteristics of light (known as structured light) projected onto the object, the scanned raster image projected onto the surface, there have been modulation of high surface deformation, and then installed at different angles by two cameras at the same time on the uptake of the image. This phase shift through the camera calibration technique and the combination, and through two cameras form a triangular intersection of three-dimensional coordinate information received. In computer vision, we use the pinhole camera model to deal with, the basic knowledge of geometry can be obtained by the following formula: = wilt --= Xc where (z, Y) for the image coordinates, (Xc, yc,) coordinates for the camera. Plant for the camera focal length. <br /> <br />相关的主题文章： <br /> <br /> <br /> <a href="http://yasinsen.forumup.com/viewtopic.php?p=20921&mforum=yasinsen#20921" target="_blank" class="postlink">ugg stivali Exchange based on the hole keyway benc</a> <br /> <br /> <a href="http://freeadvertisingnetwork.biz/entry.php?w=lomjmcfi&e_id=53450" target="_blank" class="postlink">tory burch shoes Trigger probe calibration principles and co</a> <br /> <br /> <a href="http://komunikace.potterharry.net/forum/viewtopic.php?p=436751#436751" target="_blank" class="postlink">ugg stivali Automatically determined using two-dim</a></span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
