GSM BASED SYSTEM DESIGN FOR INDUSTRIAL AUTOMATION
INTRODUCTION
This project is based on VTU syllabus. The proposed system is based on ATMEL 89S52 µcontroller that is in our syllabus.
For doing this project we use some of the software like
Embedded C for programming the application software to the microcontroller.
Protel schematic software is used for designing the circuit diagram for this project.
Express PCB software is used for designing the PCB for this project.
(Since PCB making is a big process and involves lot of machineries, which are expensive, we are going to outsource this to the manufacturer.)
ABSTRACT:
Now a day there is a lot of burglary happening across the city, the reason behind that is police can’t make out the exact location of burglary for example if burglary is happening inside any area in the city, police will get information after the incident had happened, and then they can’t find out the way the thieves had went. Now so many alarm system and security systems are emerging in our markets using high-tech techniques, but in our design we are implementing a home automation and security systems using GSM,GSM is one of the latest mobile technology using smart MODEM which can easily interfaced to embedded microcontrollers. Now everything is going to be automated using this technology, using this technology we can access the devices remotely. Using GSM and GPS now we can identify the people, vehicles etc in any where of the world.
In this project there will be sensors inside the home, if any body comes forcibly to home the sensors output will give information to the system that somebody had came, then it will send the SMS to the owners mobile or make a call to police.
COMPONENTS USED:
Power Supply 5v DC - 7805
Microcontroller - 89C51Atmel (Atmel.Com)
Crystal - 11.0592MHz
Memory - Atmel 24C04 4k EEPROM
LCD - Liquid Crystal Display 2X16
MAX232 - Serial Communication
Buzzer - Freq-1 to 18khz.Volt-5v-12vDC
Relays
Smoke sensor
PIR sensor
Panic switches
GSM Transmitter and Receiver (MODEM)
SOFTWARES USED:
Embedded C.
WORKING PRINCIPLE:
HOME AUTOMATION:
The device consists of GSM modem, microcontroller, sensors, relays, memory and display. If the user wants to control some devices in his house he/she have to send the SMS indicating the operation of the device and then the system password, while the MODEM embedded with the system microcontroller receives SMS.the microcontroller will read SMS and check for the password the user had sent with the SMS, the passwords are stored in memory, so the microcontroller will read the password from memory and compares with the message password. If the password is correct then it will check whether the message is for switch ON or OFF the devices. According to the received message the controller will switch on / off the relays.
