Modular Architecture for Industrial Automation

Industrial automation is the wide area of FPGA based nodes and zigbeebasedcommunicationdevoted to industrial applications, Commercialapplications andmedical equipment. Industrial automation which are mainly depend on the power systems and requires to control over long distances which require wireless sensor networks and Zigbee based communication systems. The wireless technology require for the sensing, processing, power monitoring and communication among the industrial machines. These can be achieved by the various technologies like FPGA Based nodes for wireless sensor networks andZigbee based communication etc. This paper proposes a digital system for the sensing, processing ,power monitoring and communication using the FPGA Based nodes for wireless sensor networks and the Zigbee based technology.The growth of sensor networks during the last years is a fact and within this field, wireless sensor networks are growing particularly as there are many applications that demand the use of many nodes even hundreds or thousands. More and more applications are emerging to solve several problems in data acquisition and control in different environments, taking advantage of this technology. In this context, hardware design of the sensor network node becomes critical to satisfy the hard constraints imposed by wireless sensor networks, like low power consumption, low size and low cost. With this goal in mind, we propose a modular architecture for the nodes, composed of four layers: communication, processing, power supply and sensing. The purpose is to minimize the redesign effort as well as to make the node flexible and adaptable to many different applications. In a first prototype of the node, we present a node with a mixed design based on a microcontroller and an FPGA for the processing layer and Zigbee technology for communications.Zigbeeprotocol as the communication medium between the transmitter and receiver modules which transfers the data efficiently.
