This will be helpful if any factory or chimney releasespolluted gas like Co2 above some specified limit, which seriously affects people’s health.When level of Co2 exceeds certain predefined level, this system will send an alarm tooperator’s mobile. For this, existing infrastructure of GSM have been used. GPS module willbe used for locating exact position of plant. In this system, controller MSP 430, gas sensorMG811 and temperature sensor LM 335 are used as core elements. In this area until now, thework done is remote measurement of CO2 and that data was sent by GSM.The GPS waseffectively used to locate the position. Here MODBUS is used which is serial communicationprotocol which will continuously update the value on local monitoring station also. so thatrequired actions can be taken immediately if it is required.GUI is also developed to monitorthe recorded data at local monitoring station only. Moreover another parameter-temperatureis also measured and updated. MODBUS is now- a -days a better option over conventionallow speed wireless channels.The precision and accuracy of recorded results of measured Co2and position from GPS have been increased. The controller used here can give response to247 different devices, which is good for future expansion of a system at low cost.KEYWORDSGPS, GSM, MG811, LM335, MSP430, MODBUS.1. INTRODUCTIONIn 21st century, as the technology advances, high speed, compact and wireless systems are indemand. Wired communication cannot meet the requirements of speed and cannot beavailable everytime, everywhere.A challenge for web services is to find reliable and efficient methods to transfer large databetween them. The development of a modular Server/Client library that uses SOAP as a 52

GSM is a wirelesscommunication technology; most popular today for transmitting data anywhere in the worldthrough SMS with the help of mobile phones.SMS is a globally accepted wireless service that enables the transmission of alphanumericmessages between mobile subscribers and external systems.In Short message service, themost attractive feature we can highlight is regular delivery of messages and moreover instantacknowledgement service.Here, the main Objective is to work for Safety of the remotely situated location,applicationfor security of the same, and Send SMS to a monitoring centre.In addition to this, GPSconcept will trace real time position of remotely situated RTU.This paper consists of five parts. In first block diagram for the proposed scheme has beenexplained. In second various sensors, which have been used are explored. In third,explanation of modbus protocol has been given. Fourth,will put some light on systemsoftware. In Fifth the results of measurements have been shown.2. DESIGNING THE SYSTEM2.1. System Hardware Fig.1 Gas Plant Monitoring System ArchitectureFigure 1 shows the complete architecture of the GAS plant monitoring System. This systemwill continuously measure the pressure of the Carbon Dioxide and temperature of the plantand continuously update the values on the local system using MODBUS protocol. Alarmswill be sending to the operator’s mobile using GSM technology. Position of the remoteterminal unit is identified using GPS module, which is interfaced with this monitoringsystem. 53

In master slave technique, only mastercan start the communication. Slave (other communicating devices) respond to the mastereither by supplying the data or by taking the action told by the master.There are two types of transmission modes. • ASCII mode • RTU modeThis mode is selected with serial communication in this specific case with baud rate but it canbe selected with parity also.Message frame and data frame are two different things. Dataframe structure depends on transmission mode. ASCII Mode messages start with a coloncharacter ":" (ASCII 3AH) and end with a carriage return-line feed pair of characters (CRLF,ASCII 0DH & 0AH). The only allowable characters for all other fields are hexadecimal 0-9& A-F [3]. MODBUS transaction (error free) MODBUS settings View data 56

CONCLUSIONThe remote GAS Plant monitoring system based on GSM and GPS has three features. Firstly, all thedata collected by the system will be directly transmitted through MODBUS protocol. Secondly, thesystem can automatically send alarms to the supervision staffs by the GSM network. Third, the systemcan provide the location of the remote terminal unit using GPS system. At the same time, with theadvantages of small size, real-time communication, inexpensive and easy to maintain, the system alsohas tremendous superiorities when compared with the expensive monitor system used by theenvironmental supervision and management departments imported from foreign country.4.
