Design And Implementation Of Multi Equipment Data Acquisition System Based On Soap

Nowadays, with the development of computer、communication, Many companies improve industrial automation continuously, CAN bus, RS232, RS485serial communication and other means of it have been unable to adapt to new forms of development. In the field of industrial electronics, industrial electronics management systems and Internet combine to achieve convenient and reliable remote data collection, transmission and control, is research focus within the industry.To promote automation, modern enterprise information management, to provide real-time on-site data, scheduling and management, through the network transmission to the computer at the same time, also hope that data acquisition terminals of different system can realize mutual access, data sharing, the data acquisition system contain Cortex-M3microprocessor, uCOS-II, uIP, SOAP protocol, server software and ect, this methor has certain forward-looking. The data acquisition system with Ethernet module is presented in the paper, in order to combine with Internet, transmission and make control of remote data acquisition convenient and reliable in industrial electrical appliances, industrial electrical equipment, management system.On the basis of the SOAP technology, in the form of XML,it provides a simple, lightweight used in the dispersion mechanism of exchanging structured information in distributed environment, to solve the problem of interoperability between heterogeneous applications and Internet platform in the environment with simple method, which is the main purpose of this design.The paper will study from the following aspects:1. analyse network communication theory and basic principle, decide the network structure of system;2. research the network chip, network protocol stack;3.study on SOAP、 HTTP protocol, allowing system to achieve webserver function;4.research on system stability, security and testing technology.Various tests show that the system hardware, network layer protocol stack is working properly, the system can achieve network communication based on SOAP protocol, it can be network server and send control command, also can timely receipt and execution, it can correct the important data to the control terminal.
