| The subject is made under the background of ZRJ-03C intelligent thermal verification instrument device upgrading projects of Taian Panran Measurement & Control Scl-Tech.,Ltd. An thermal verification instrument device with Windows CE embedded operating system is designed and realized according to analysis and optimization of hardware and software.Also,this device is designed in line with the requirements of relevant verification regulations. The device take full advantage of embedded operating systems features which including high reliability, powerful, flexible and convenient.Thus, embedded technology will be applied to the traditional areas of measurement industry. At the same time,a signal source which special used for thermal industry field is designed. And get a good result in practice.As to the hardware, the subject designed a industrial control board which use S3C2410 as processor and include variety of memories and communication interfaces. In addition, the subject also make a detailed analysis of signal source which as a part of verification instrument device.This analysis include working principle of signal source, PCB design of D / A converter, selection of low-pass filter, temperature coefficient control and so on.As to software,a optimized Windows CE5.0 image is generated by Platform Builder 5.0. The verification instrument device software based on Windows CE5.0 operating system is Programmed by EVC.The software implement the hardware configuration and the verification instrument device for all control functions which include information Window on initial, host computer interface and the main menu bar design.At last,realize the design objective of using S3C2410 industrial control board to replace the general computer. In addition, the subject also make a detailed analysis of software design of signal source.The device is expected to achieve the full functionality through on-site verification instrument device debugging, and have achieved ideal results.
