INTRODUCTION Mobile phones have evolved from their usual function of calling to a lot more in the last decade, the 4G networks are being used for microwave access, But the use of mobile in field of Telemonitoring is still a open issue. In this paper we propose a system which uses NFC(Near Field Communication) in mobile phones for monitoring various machine related details such as current, voltage, vibration, inter dislocation, etc.. NFC (Near Field Communication) is a short range wireless RFID technology that supports a closecoupled device communication. When two parties come near at distances of a few centimeters, some transaction automatically starts. One party becomes inactive behaving as an NFC tag while the other party reads information from the tag to start an appropriate action. Besides, through any WiFi - enabled consumer electronic devices such as a smartphone or pocket PC, a manager/supervisor can easily access such real-time analysis about a particular machine, from anywhere inside of the plant through access point and also through GSM we can get the particular event of plant from anywhere inside of the plant. Interactive Data Acquisition Control System is a new system that contains inbuilt data acquisition and control system with online interaction. This server is network intelligent and it controls the application in any system. Replaces various complex cables and it uses the ARM processor for data acquisition and digital diagnosis. It maintains separate data base with Data Acquisition Controller. This system is more reliable and avoids more complication. Signals are the major part of the data acquisition unit. With the rapid development of the field of industrial process control and the fast popularization of embedded ARM processor it has been a trend that ARM processor can substitute the single chip to realize data acquisition and control. Embedded ARM system can adapt the necessary requirements of the data acquisition system, such as the function, cost, size, power consumption and so on. A new kind of embedded ARM platform has been introduced to implement efficient & high performance remote I/O data acquisition and control system (DACS) and embedded web server. This system can measure and store any kind of electrical and non-electrical signals in embedded web server. And it can control the devices remotely. By using NFC card, the secure access of information can be obtained.

NFC CARD The NFC card contains a chip and an antenna that The main aim of this project to develop an embedded system to collect the metadata (self describing data about sensor nodes and sensing data), and monitor the efficiency of workflow using wireless sensors networks in industries. Numerous low-cost and customizable sensor nodes to measure various parameters such as temperature and vibration etc., are installed in different corners of a manufacturing plant or testing plant in an industry. And also RF readers are placed at necessary points in the industry to monitor the location of the employees. The RF reader also can be placed in the machineries to monitor the presence of the employees near by the machineries and also to provide authenticated operation in the machine for security purpose. All the data are collected in a dedicated server through a common wireless receiver node. The data from the server can be accessed from anywhere in the industry using LAN (Local Area Network). transmit data to a mobile device when the card and the device are tapped together (the same system is used in many transit cards and door entry systems). It s possible to rewrite NFC cards over and over, so they never go out of date, or write it so that you control the card even after you ve handed it out the possibilities are truly endless. Besides, through any WiFi - enabled consumer electronic devices such as a smart-phone or pocket PC, or through mobile phone, a manager/supervisor can easily access such real-time data about a particular machine, from anywhere inside of the plant through access point, or outside of the plant using GSM technology.

3 each unit in an industry. For example, Temperature and vibration measurement sensor nodes in testing unit or production path flow sensor node in production unit etc., All the machineries or selected complicated machineries have a sensor node with a RF reader to identify the employees near by the machineries. The node indentifies the employees nearby it by reading the RF-iD tags wearable by employees. So the information about the presence of employees near by the machineries also is sent to the server and updated. So we can monitor the presence of employees from anywhere. All the data are collected using a common receiver terminal and stored in a dedicated server or database. All the data can be accessed from anywhere inside the building using PC in LAN or using Wi-Fi enabled PDA devices through access-point. All the data or data with high priority can be monitored from anywhere outside using mobile phone through GSM technology. Here for the demonstration we are taking current, voltage and vibration level in the testing unit node and object counter in the production path in the production unit and ID node to identify the employees who are wearing RF-iD tag. WIRELESS SENSOR NODES Sensor Node for Testing Unit: Fig.4 Sensor Node for Testing Unit The above block diagram shows the example sensor node for the testing unit of an industry or laboratory. The node consists of current sensor, voltage sensor and vibration sensors interfaced with low power microcontroller and 2.4GHz zigbee RF module. The MEMS which stands for Micro Electro Mechanical System, a 3g or 2g accelerometer used to detect the machine vibration level. Then the CT stands for Current Transformer which is used to measure the current flows through the machine. And then the PT stands for Potential Transformer which is used to measure the voltage flows through the machine. All the sensors interfaced with ADC which converts the analogue data into digital and sends it to the microcontroller. Microcontroller further sends the data to the zigbee module which transmit the data as radio frequency in the 2.4GHz band. Sensor Node for Production Unit: Fig.5 Sensor Node for Production Unit The above block diagram shows the example sensor node for the production unit of an industry. The sensor node consists of an IR transmit-receive pair or transceiver interfaced with the microcontroller, which is placed on the production path (conveyer belt etc,) to count the objects.each time when an object crosses the IR path between transmitter and receiver, gets cut and a high pulse is sent to the microcontroller, which is counted. The counted number is stored by the microcontroller and sent to the RF module. Sensor Node for Identification: Fig.6 Sensor Node for Identification chiefeditor@ijrcct.org Page 155

4 The sensor node consists of a RF reader to read the nearby RF tag. The RF tag is a wearable one by the employees for identification. We can configure the microcontroller to give authorized operation with the machine. So based on the identified person the machine may allow the user to do a particular job only. IV. MONITORING SYSTEM The below diagram shows the block diagram of monitoring unit. The receiver unit consists of a zigbee RF module with microcontroller which is interfaced with a dedicated server PC. The server consists of software developed by Visual Basic, which maintains the database for the collected information. The software sends a command via the RF module, to each node at a particular interval of time to get the data. Then the collected data is stored and maintained in a database. The software also consists of a GUI (Graphical User Interface) based menu, which allows the user to access those datas easily. user mobile. The mobile numbers of the users (who are all wants to access the data) are given to the PC using the software developed by the visual basic. V. CONCLUSION A plug and play is an important issue to deal with heterogeneous, application specific sensor networks. However, resource constrained wireless sensor networks require different considerations from established plug and play approaches. Storing is severely resource constrained sensor nodes and transferring them via multi-hop communications increases memory cost and communication overheads. More than this, sensor networks have difficulties in supporting XML or similar high description models useful for applications or users. So we proposed new approach to store them in distributed servers on the internet or intranet instead of sensor nodes. It minimizes the metadata overhead and it also enables effective sensor node discovery by changing networked discovery problems to a local attribute search problem. However, throughout this paper we limited our concerns to static metadata and a discovery support in the centralized sensor network architecture. Generalizing the proposed approach based on stimulated analysis will be the future update. VI.
