Abstract: – Nowadays its very common to use automation in industries. Ac motors are the nerve of many industries. Hence, the automation is much needed for accuracy and reliable operation. This project proposes a system on wireless control and monitoring different parameters of induction motors based on zigbee technology. Due to this, there will be safe data transfer communication in industrial field where the other mode of data transfer communication is more expensive than zigbee or impossible due to some physical conditions. On this design, there will be a set of transducer and sensor monitors the parameters of Induction motor and transmit its data through zigbee. An Arduino based system is used for collecting and storing data and accordingly generating control signal to stop or start the AC machine wireless through computer interface developed with Zigbee. This Techniques has different sensors to monitor and measure different parameters of induction motor and the data is transmitted to control room i.e., drive using zigbee wireless protocol. The overall control like starting and stopping of motor can be done with zigbee that is already interfaced with computer. It also protects motor against some faults such as over current, over heating in winding, under lover voltage, data acquisition system saves all received parameters data of motor in the database.

Keywords: Induction motor (IM), Zigbee, Arduino, Current Sensor, Temperature Sensor, voltage sensor, Pc.

  1. INTRODUCTION

    Induction motors are mostly preferred in all Industries. The reason for using industrial motor is because, they are self- starting, economical and reliable. Although they have sufficient features, and simple structure they undergoes several stresses which creates faults which finally ends in failure. To treat these conditions several controlling in motors are needed.

    For a reliable operation of motors, they are several datas which plays a major role to control its operation. The datas like current, voltage, temperature and speed decides the performance of Induction motors and drive systems. These parameters directly affects these Motors efficiency and reliability. However, while using Induction motor in Industries, there will be continuous process of motor for these production. On that time if any faults occurs it becomes risky and also very operation to control the motors. The only way for controlling these hazards was to monitor these parameters. Its impossible to monitor these parameters for 24×7 by humans. So, wireless communication technique for transforming datas from machine to drive is needed, which is used in most of industries.

    There are different ways in monitoring Induction motor which was been discovered by many reviewers and researchers. Although, we have different methods in monitoring and controlling Induction motors, still we faces critical problem in Industries, this is because the problem in Induction motors should be found at initial stages. So, that we can rectify it before it creates a large fault. For detection of fault we need fast emerging technology. It should withstand its monitoring and control for all initial faults and also unexpected faults.

    Still in most of industries and automation applications, the traditional methods are used i.e., wired technology. Although wired technology operations are designed to meet several hard situations sometimes it creates failures at last. But wired technology was also designed in same way the only difference is that it doesnt have any physical connections. So, that the data communications in wireless manner will be fast as its compared to wired technology.

    In some existing system, there are different methods has been introduced for monitoring, detecting mechanical stresses, controlling temperature in Induction motor. But they didnt fulfill all the controlling and also has some disadvantages, the methodology used will be costlier.

    Our proposed system will overcome these defects as we used different protocols like voltage sensors, current sensors, temperature sensors for automatic controlling and interfacing we have used Arduino. In Desktop computer the C programming were done to design the interface and finally communication. We have used Zigbee methodology which was more efficient than other methods and also cost efficient.

    This paper was organized as Section II Wireless Methodology, Section III Proposed.

  2. WIRELESS METHODOLOGY

    For remote philosophy the zigbee convention was utilized. Zigbee plays as a transmitter between beneficiary among Drive and Enlistment engine. On IEEE 802.15.4 norm for remote individual territory organizations (WPANs), it is utilized for correspondence of zigbee among control and sensor organization and it is the item from Zigbee partnership. This IEEE standard principally characterizes the correspondence among physical and Media Access Control (Macintosh) layers to deal with the various gadgets with low-information rates.

    The WPANs of these sort of zigbee's work at 868 MHz, 902-928MHz and 2.4 GHz frequencies. It is most appropriate for intermittent just as middle two path transmission of information among sensors and regulators at the date pace of 250 kbps is. It has three sorts of organization lattice, tree, and star network for these geography associations. The quantity of switches, organizers, and end gadgets relies upon the sort of organization utilized.

    Features of Zigbee module:

    • Cost efficient.

    • Th maximum data rate for a Zigbee device is 250Kbps because it has low data rate. Reliable.

    • It can ends upto 65000 nodes in a network.

    • It automatically establish it desired network.

    • It uses very small packets when has compared to Bluetooth and WIFI.

    Zigbee specifies itself with three different devices. They are Zigbee Coordinator (ZC), Zigbee Router (RC), Zigbee End devices (ZED).

    ZIGBEE COORDINATOR (ZC):

    Zigbee coordinator is one of the devices in Zigbee. It was used for channel selection. It assign an ID for the network. It allocates unique address to each devices and also it initiates and transfer messages to network.

    ZIGBEE ROUTER (ZR):

    Zigbee Router act as intermediate nodes between the coordinator and the end devices. It router traffic between different nodes. It receives and stores messages intended for their children.

    ZIGBEE END DEVICE (ZED):

    Zigbee End devices contains just enough information to talk to the parent node. They may sleep which make end devices more suitable choices for battery operated devices. All traffic to an end devices is first routed to its parent. Examined in two main categories as hardware and software. The functions of the each part of the system are described in the following sections in detail.
