ABSTRACT

 In this paper we have developed an integrated wireless SCADA system for monitoring & accessing the performance of remotely situated device parameter such as temperature, pressure, humidity on real time basis. For this we have used the infrastructure of the existing mobile network, which is based on GPRS technique Supervisory Control and Data Acquisition (SCADA) is a field of constant development and research

                    GPRS is a packet-based radio service that enables “always on” connections, eliminating repetitive and time-consuming dial-up connections. It will also provide real throughput in excess of 40 Kbps, about the same speed as an excellent landline analog modem connection. From the wireless SCADA system which is proposed in setup the temperature of around 30oC could be sufficiently recorded from remote location.

                    In the similar manner reading of electric energy meter could be read 223 Kilo Watt Hour (KWH) or 223 Unit. The properly designed SCADA system saves time and money by eliminating the need of service personal to visit each site for inspection, data collection /logging or make adjustments.

 INTRODUCTION

                        

Supervisory Control and Data Acquisition (SCADA) is a process control system that enables a site operator to monitor and control processes that are distributed among various remote sites. Supervisory Control and Data Acquisition systems are computers, controllers, instruments; actuators, networks, and interfaces that manage the control of automated industrial processes and allow analysis of those systems through data collection .They are used in all types of industries, from electrical distribution systems, to food processing, to facility security alarms. Supervisory control and data acquisition is used to describe a system where both data acquisition and supervisory control are performed. Mobile Supervisory Control and Data Acquisition (referred to as Mobile SCADA) is the use of SCADA with the mobile phone network being used as the underlying communication medium. GSM is a wireless communication technology; most popular today for transmitting data anywhere in the world through SMS with the help of mobile phones SMS is a globally accepted wireless service that enables the transmission of alphanumeric messages between mobile subscribers and external systems such as electronic mail, paging, and voice-mail systems.

CONCLUSION AND FUTURE SCOPE

Our objective is to work on the “Remote site Safety & security Application by using Controller” to achieve to produce an input data file for each of the Data Logger, build a Controller Area network ,Collect & manage data in the Control Area Network(CAN) and Send SMS to a monitoring centered .

                    GSM communication performed almost flawlessly data transfer from sensor at remote area was executed Without incidents. In this project all the database is stored in a central database in the data logger; user has global access to consolidate data from many system or locations.

                With the proposed setup in Figure 3 temperature was successfully monitored remote location and it was measured to be around 30oC. Similarly energy meter reading from remote location was also successfully implemented using demonstrated hardware setup of wireless SCADA system.

Hence the wireless SCADA system is powerful setup for monitoring and controlling the various applications from remotely placed location. various area of application like health monitoring system, Home security system, Vehicle Security system etc.
