Abstract: Aiming at the data processing task in the central console of a certain large-scale equipment for photo-electronic measure, a programming method about how to establish data plat form using the Bit Field and Union was discussed. Configuration of the large-scale equipment for photo-electronic measure was introduced. The data processing and the data stream of the central console was analyzed . The programming method was detailed introduced. Practice shows that, this method has minimal memory required which makes the program run faster, and it was good at progressing and maintenance also. Therefore, the method can meets the design requirements and can solves the same problems.
Keywords: Data plat form; Engineering application; C++
