AbstractIn this paper, a distributed real time security system for monitoring and remote control on building and protecting it from unauthorized entering is designed and implemented. This system is based on the transfer of signal in real time when there is a breach and image of an unauthorized person to enter the building to the mobile phone of the person who is responsible for the security of the building.
The real time system consists of three main parts, the first one is the computer with an electronic circuit connected via the serial port. The designed electronic circuit contains the Microcontroller for reading sensors connected to ports of the building (G1, G2, and G3) and processing the signals. Also, there is a monitoring camera to capture an image when registering a case of breach. The program in the computer receives signals from the three ports and uses a fixed real time algorithm for scheduling signals and gives them priorities according to the importance of ports, then sends signals to the second part of the system. The second part of the system consists of a server on the Internet which receives signal and image of the breach, stores it in a database system and then transferring it in real time to the third part. The third part consists of several mobile phones to achieve the principle of distribution for this system, each mobile phone will be responsible for a single port in the building, while there is one mobile phone responsible for all ports which belongs to the person who is responsible for the building security. Each mobile phone contains three programs, the first program would receive a signal of the breach and give the alarm, the second program displays picture, and the third program sends a control signal.
