Ethernet public address system
Student: Aaron Chambers
Supervisor: Neil Bergmann
Category: Engineering Thesis Project - Computer Systems
The Ethernet Public Address System (EPAS) has been developed to allow a CAT5 wired building to utilise a computer network to provide a public address system throughout.
The EPAS consists of a control application and a number of microphone and speaker modules connected to the network at various locations. The Ethernet standard is used to facilitate communication between connected devices and utilises TCP/IP and UDP/IP protocols. When a "module" is first connected to the network the DHCP server will dynamically assign an IP address to the device. The control application can issue commands to a microphone "module" to send its data to one or many connected speaker "modules"
Each microphone and speaker module consists of a RabbitCore 2000 processor interfaced to the MAS3587F MP3 CODEC. The CODEC performs all the data processing of the input and output sound with the RabbitCore soley responsible for sending and receiving the MP3 data from the network.
