Gsm based industrial security system

  1. 1. GSM Based Industrial Security System RAJASHREE.B
  2. 2. EMBEDDED SYSTEM Definition of embedded system Examples of embedded systems.
  3. 3. Microprocessors and microcontrollers are widely used in embedded systems products. Microcontroller is a programmable device. Components present in the microcontroller Microcontroller are used in the applications which cost and space are critical.
  4. 4. VON-NEUMANN ARCHITECTURE
  5. 5. HARVARD ARCHITECTURE Microcontrollers using this architecture have two different data buses. One is 8-bit wide and connects CPU to RAM memory. Another one consists of several lines (12, 14 or 16) and connects CPU to ROM memory
  6. 6. MAIN APPLICATION OF PROJECT ATmega48/88 Microcontroller has been programmed to sense the unauthorized person and fire. SIM card is used in the modem. GSM modem can be controlled by standard set of AT (Attention) commands. In this module IR sensor, touch sensor, LDR sensor and temperature sensor are used.  
  7. 7.  Here ir, touch and ldr sensors are used for intruder alert through message to the concerned mobile number.  Temperature sensor is used for fire alert I.e. if there is very high temperature which acts as a source for fire then module gives an alert to the user    
  8. 8. BLOCK DIAGRAM
  9. 9. HARDWARE COMPONENTS REQUIRED         ATmega32(8-bit microcontroller) LM 7805 MAX232 GSM MODEM IR SENSOR LDR TOUCH SENSOR TEMPERATURE SENSOR
  10. 10. PIN Diagram Of Micro Controller Of ATmega32 PIN Diagram Of Micro Controller Of ATmega32 The microcontroller is at the core of every embedded module  The Atmega32is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture
  11. 11.  A voltage regulator based on an active device (such as a bipolar junction transistor, field effect transistor or vacuum tube) operating in its "linear region" and passive devices like zener diodes operated in their breakdown region.
  12. 12.  We need a line driver to convert the RS232’s signals to TTL voltage levels that will be acceptable to the microcontroller’s TxD and RxD pins.  One example of such a converter is MAX232 from Maxim Corp. The MAX232 converts the RS232 voltage levels to TTL voltage levels, and vice versa.
  13. 13. GSM modem is used for wireless data transfer. The GSM Terminal is ideal for embedded applications. Modem can communicate serially by RS232. The GSM module offers the advantages as below •Small, lightweight and easy to integrate. •Low power consumption
  14. 14. Descriptions of the pins used:  Power ON / OFF control  Tx  Rx
  15. 15.  A Passive Infrared sensor (PIR sensor) is an electronic device that measures infrared (IR) light radiating from objects in its field of view.
  16. 16.  LDRs or Light Dependent Resistors are very useful especially in light/dark sensor circuits.
  17. 17.  A touch sensor is classified as a high impedance device (or high impedance circuit) as the effect of a finger will be detected by the circuit connected to the plate.
  18. 18.  The LM35 series are precision integrated-circuit temperature sensor.  Calibrated directly in ° Celsius (Centigrade)  Suitable for remote applications  Operates from 4 to 30 volts
  19. 19.  CVAVR cross compiler  AVR studio programmer  Embedded C
  20. 20.    Much easier to have security. Both risk and liability is reduced. It is flexible enough to be used from any location.24 hrs/Day and 7 days a week.
  21. 21.   High end security for industries High end security for museums.  High end security for colleges.  High end security for Offices.
  22. 22. The design approach used here has given satisfactory results and the microcontroller is sufficient for measuring the required parameters. The power consumption has been kept as low as possible.
