THEME - Hard & Soft 1996 - A local Building Security System

A building has to be provided with a security system that includes a host computer (IBM PC compatible) and local room units. It has to be an open system that allows to increase the number of local units from 2 to 256.
The system has a multilevel structure with the following minimal functions:

The host computer:

• Will support a data base management system with some access rstrictions. The main information items which are to be stored in the data base are: the access code, the person identity, the room number, the access time interval;
• Will provide a user friendly interface with the system manager in order to use the data base (e. g. changing access codes, getting reports);
• Will control local security modules via communication lines;
• Will test and monitor the whole security system.

The local units:

• Every room has its own local unit which can work independently;
• Will identify a person by his/her unique personal key and will grant the access to the room accordingly with the corresponding time table;
• Should be able to work in some critical situations like the absence of communication with the host computer, the local power supply falling-down, etc. In such situations, the local unit has to grant restricted access to some privileged persons;
• Have to indicate their current state outside the room and to signal the access permission by a blinking LED;
• In addition to allowing access to the room, a local unit is also provided with at most 8 sensors to protect the room against events like intrusion or fire in the room.
   

Notes:

The access code will be provided with a 25 pins father connector having the pins 1 to 13 grounded and 14 (MSB) to 21 information pins, which may be wired ground.

Each team has to implement two identical local units and two different keys.

Any other additional facilities will be rewarded.
