ng, processing and memory storage capabilities to control ponents uesd danpianji wisdom meters into the upgrading of industrial products and advanced technology are economic means. Maintain a peak capacity. Rotational speed changes to the memory of the greatest rotational speed values. A black box function. To the permanent preservation of important rotational speed data for accident analysis, review appliacations, normal circumstances can provide data analysis. Amendment can be preserved to the different requirements of print intervals. Thereby speeding access to test data, a maximum speed of data. Antiinterference capability. On the important of abroader range of adaptive signal. Applicable to electromagic type, photoelectric type fluid style, and many other sensors to produce one pulse per or 60 (60) business, the meters particularly suited to the testing plant housing units rotational speed, control, similar to other mining industry uses also apply. Meters into measurement, display, interactive,and print several of the police. Smart devices are microprocessors at the core of electronic equipment, hardware circuit design of the ponents to the mastery of the principles of work, but also for its mastery of microputer hardware principles. The general wisdom equipment design steps: first, it is necessary to determine the design of the mission, to prepare the design task sheets, equipment should have clear functions and should meet the technical requirements, design of mission statement is the basis for the design designers should strive to accurate precision。 and then to design programmers to develop, at this stage, designers must make several design options, Each programme should include equipment design principles, using the technology, the key ponents of performance: then to conduct a feasibility study on the programme. including some important part of theoretical analysis and calculation, and the necessary s
