[Abstract]:With the development of modern industry, the degree of industrial automation is more and more high. Instruments and meters used for data analysis and industrial control have been widely applied in modern industry. Data acquisition through manual meter reading can not meet the demand for data acquisition in industrial field. The appearance of intelligent instruments based on field bus has brought great convenience to meter reading. Most of these intelligent instruments are Modbus, Meterbus, DLT-645 and other protocols. The appearance of these instruments has caused many automatic meter reading systems, but the compatibility of these automatic meter reading systems is poor. In this era of big data, with the expansion of industrial scale and enhance the degree of complexity, the number of control objects and control points is greatly increased, and with many instruments for data analysis to obtain real-time data, the existing control system has been unable to meet the increasingly complex needs. In order to be compatible with different protocol types and achieve real-time data transmission, we propose an industrial data acquisition gateway supporting multiple protocols and real-time data transmission. The data acquisition gateway is based on the research and design of the Samsung S3C2440A microprocessor and the Linux operating system. The hardware includes a processor based on ARM9 architecture, 8 sets of serial ports expanded by ST16C554, etc. each serial port contains a RS-232 interface and a RS-485 interface. The software gateway supports the acquisition of intelligent instruments based on Modbus protocol, Meterbus protocol and DLT-645 protocol. In this paper, we first analyze the protocols and core technologies used in this subject, and then design the software architecture of data gateway, and implement the software based on this framework. This paper mainly presents the research and implementation of some key technologies of data gateway. At last, we test the data gateway and research and analyze the test results. From the result, the gateway realizes data collection, reporting and reporting in real time.
