Abstract :

             In an approach to diagnose the various types of fault, generally occurred in Induction machines, this paper describes a monitoring and analysis system. The induction machine model and its various types of fault are simulated using a Real Time Digital Simulation (RTDS) unit. The signal corresponding to the simulation can be taken out of the RTDS unit which is interfaced with a microcontroller for its acquisition in a PC. The PC based software can store it and the fault detection algorithm (sequence component based) runs over it to detect and diagnose the fault. The multitasking is a process to perform a more than one application or task at concurrently, it means possible to perform a so many operations at the same time. In the normal operating systems are not supported this type of multitasking. So in this project we are implementing RTOS concepts. The main advantage of RTOS is multitasking and time scheduling and rescheduling etc. In RTOS due to the internal minimum time delay of the time scheduling process it will give the output with in the specified time. However, due to the lack of uniform programming model and system components for these different teams, the migrations costs of a function model from software to hardware are high. But these actions are necessary in the hardware-software partitioning of embedded systems, especially in the prototype designs. To cope with this problem, we adopt a uniform multi-task model and implement UCOS II RTOS (Red- Time Operating System). The advantage of RTOS multitasking and time scheduling is get better accuracy and with  high operating speed  and processing time is less. In this project the devices will processed by multitasking. Using this RTOS architecture ARM processor give the signals to all devices, it will operated my multitasking and time scheduling. So we get the output for all devices with in the specified time interval.
