Design And Realization Of A Portable Data Acquisition Instrument's Battery Manage System

With the social development and progress, the mechanical equipment are largely used in our life. The incessant emergence of new technology makes the machine integration, complication and intelligentize and the overhaul and maintenance are more and more important.Fault diagnosis and inspection are rapidly developmental as a new subject. The portable data acquisition instrument by right of its miniaturization and enchiridion has become the magistral product of fault diagnosis instrument and leaded the developmental direction.The paper compares and introduces several new batteries capability and developmental actuality based on prevenient power supply of portable data acquisition instrument and brings forward a straightforward, reliable project of intellectualized battery management system which unites the actual demand and intending application founded on the popular 1-wire bus technology. The paper fully expatiates the bascial concept and communication protocolcommunication protocols of 1-wires bus technology.It presents the basal configuration and work principle of the DS2770, DS2720, DS2415 chip made in Dallas corporation and designs the intellective management charge module of. About the soft design, in allusion to the special characteristic of 1-wires bus, in the aspect of the visit and control on the host to the 1-wire bus, the paper narrates the search of the 1-wire bus, read/write to different part and the dependability of assuring communications, and expatiates the process searched, arithmetic searched and the way that assures the dependability by using of soft control in the course of communications time. What's more, through transferring the API function, the paper lists some program.As a research hotspot, the management system of intellective battey has an extensive applied field. Certainly, the research to the system need be consummated and ameliorated and it is fully necessary to investigate roundly to the technology. The paper accomplishes the framework design and naturalization of some soft.
