Abstract
RTOS (Real Time Operating System) is a Process which is done between hardware and application in order to provide time constraints. Each industry has their own priority among the various tasks according to their process. RTOS is used here to assign the priorities. The values obtained in plant have to be transmitted to the control room. These values are sent in the form of packets. Packets have to be sent at particular time. During the packets transmission some collision may occur. To overcome this collision wireless HART (Highway Addressable Remote Transducer) is used. This project is implemented in two sections as prototype. First one runs with RTOS and LPC2148 as master node and another as normal data acquisition node to which sensors are connected. Second section contains a controller as per the need. Communications between two nodes are accomplished through wireless HART. The basic view of this technique is to reduce the possibility of collision (and thus increase the communication reliability), and to meet the critical requirement of industrial applications. This is essential to increase the communication reliability, and to meet the requirement of timing determinism of industrial applications. To do this, all the nodes must be synchronized precisely. Also, the stack designer must guarantee that the node can finish everything within the time slot. It offers benefits in terms of platform independency, product life cycle, safety and security, system integration complexity, and performance scalability.
