Industrial safety and security system with voice alerts and message alert through GSM-VOICE PLAYBACK

Industrial safety and security system with voice alerts and message alert through GSM


Security is primary concern for every one. There are many ways to provide security at industries. This Project describes a design of effective security alarm system that can monitor the industries or some shops with different sensors and sends alert messages through GSM modem. And this system also gives voice alert to nearest people about so that they will alert from danger

This project is mainly useful in shops, apartments, banks and in industries. In this project we will monitor fire accidents, gas leakages, over temperature, entering into no access zone, etc. 

If any sensor detects abnormal condition then micro controller will give voice alert about that danger situation and also sends message to authorized person’s mobile using GSM.

To play the voice messages we do not need any separate voice module because we can play that voice from ARM7 LPC2148 micro controller directly by saving pre recorded voice message in micro controller’s memory in the form of binary. 

And to send messages we are using GSM modem. This modem provides the communication interface. It transports device protocols transparently over the network through a serial interface. The GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.
