The Design And Implementation Of Multi-configuration Data Acquisition Module

As mankind enters the21st century, computer science and technology, informationscience and technology and automation and control technology is widely used in the scene ofindustrial production, the data transmission is an important part of industrial production.Traditional data concentrator features a single bus interface is too small, the shortcomings ofthe data processing capacity has gradually keep up with the times, the new data transmissionsystem is imminent.Communication interface M_BUS master/repeater use European instrument the busM_BUS technology, instead of the traditional RS485bus, has a great advantage in terms ofdata transmission. For PROFIBUS, CAN bus M_BUS bus and Ethernet technologies, theirtechnology is mature, stable and high-performance, wide range of applications in theindustrial production data transmission link applications is extremely broad, and embeddedtechnology as today’s new technologies on behalf of widely used also in production practiceso PROFIBUS, CAN bus technology, M_BUS bus and Ethernet technology and embeddedcombination of LPC2387of NXP as the core control chip, the successful realization of dataM_BUS from the node two-way transmission of data between the PROFIBUS, CAN bus andEthernet. The communication interface M_BUS master/repeater downlink interface isMBUS bus technology, the uplink interface, Profibus bus, CAN bus and Ethernetcommunications technology, taking into account the versatility of design M_BUS repeaterinterface, increasing the the the MBUS slave data transmission distance.Compensate for the lack of conventional data transmission system for the design of thecommunication interface MBUS master/repeater system functional testing, communicationinterface the MBUS main station/repeater in line with actual requirements, can be used for avariety of industrial production occasions.
