Badge Tracking System Design

Level 1 System Diagram

The basic system design will involve three distinct, separate modules: Sensor Module, Data Module, and Interface Module. The three modules will be connected to each other and able to communicate differently, depending on the module source and destination. For example, the Sensor Module may receive commands and/or status updates from the Interface Module, but only sends out the data it collects to the Data Module. The separate modules may be contained entirely on a single physical server, or may be split up into as many as three different servers. If the modules are split up into different servers, the connections between them will be tunneled through an OpenSSH secure session to help protect against data theft and maintain a secure system.

The design considerations for each of the three modules can be found in their respective pages:

• Sensor Module
• Data Module
• Interface Module

The Integration Thread illustrates the design needed for baseline functionality of the system, and can be found in its own page:
