Design of Embedded Controller for Web-Based Remote Diagnostics of Electrical Drives

Abstract

Electrical energy is finding increasing application in industrial and commercial fields. An electrical drive possesses a number of inherent advantages over other forms of conventional drives. Faults occurring in electrical drives must be carefully dealt with. This paper describes the design and implementation of distributed embedded system to diagnose the faults in electrical drives from the remote place through a web page considering various parameters like voltage, speed, vibration etc. This system design uses an embedded processor module, web-based system comprising ethernet module, bus interface and communication module. Here the drives, which are to be controlled, are connected through the bus on the web server. The web server is connected to the LAN. The client PC is also connected to the same LAN. By typing the IP-address of PC on the web server, the user gets a web page on screen that contains all the information about the status of the drives. The user can also control the drives interfaced to the web-server. Occurrence of faults, variation in parameters is found through remote diagnostics. SPI communication module connects processor and the Ethernet modules. The system aimed at consuming less power, hardware complexity is reduced using embedded processor and the terminal data can be transmitted and received efficiently.
