Design of on line interactive data acquisition and control system for embedded real time applications

  1. 1. DESIGN OF ON-LINE INTERACTIVE DATA ACQUISITION AND CONTROL SYSTEM FOR EMBEDDED REAL TIME APPLICATIONS Abstract Design of on-line embedded web server is a challenging part of many embedded and real time data acquisition and control system applications. The World Wide Web is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billion of users worldwide and allows the user to interface many real time embedded applications like data acquisition, Industrial automations and safety measures etc,. This paper approached towards the design and development of on-line Interactive Data Acquisition and Control System (IDACS) using ARM based embedded web server. It can be a network, intelligent and digital distributed control system. Single chip IDACS method improves the processing capability of a system and overcomes the problem of poor real time and reliability. This system uses ARM Processor portability. Web server application is ported into an ARM processor using embedded ‘C’ language. Web pages are written by Hyper text markup language (HTML); it is beneficial for real time IDACS, Mission critical applications, ATM networks and more. Existing System: In existing system, the collected information is continuously monitored with the help of LCD or any other display unit. It is not possible to get the information from anywhere in the world. Proposed System: Online Interactive Data Acquisition and Control system plays the major role in the rapid development of the fast popularization and control in the field of measurement and control systems. It has been designed with the help of many electrical, electronic equipments; it makes the system more complicated and not reliable. This paper approaches a new system that contains inbuilt Data Acquisition and Control system (DACS) with on-line interaction. Here, the ARM processor is interfaced with PC using UART communication. Industrial device temperature and
  2. 2. current values are measured by corresponding sensor and fed to ARM processor. The sensor output is analog signal. The sensor analog voltage is fed to ARM processor, the ARM processor is having inbuilt ADC and it converts the analog voltage into digital form. Then the ARM processor send information to PC using UART serial communication. In PC, the sensor values are uploaded to internet using .NET application. If sensor value exceeds the threshold value then the device automatically controlled using ARM processor.
