SYSTEM DESCRIPTION

The Bussmann InVision
transmitted about the status of sensors monitoring overcurrent protection devices with in a
facility. The system uses a mesh network topology to enable highly reliable data
transmission. The data is then sent to a web based portal. The portal allows the user to
define how they wish to be notified upon an event occurring with in the network of sensors
they are monitoring. The network operates in the 900MHz range of the ISM band of the
frequency spectrum.

The sensors operate on a different frequency from the data transport layer of the network.
The mesh network operates on a second frequency. This allows for the system to have a
high reliability and minimize data collisions.

GATEWAY DESCRIPTION

TM

Network is a wireless sensor network that will allow data to be

The gateway is the central point for data collection and transmission to the web based
portal. The gateway is comprised of several separate sub-systems. It contains a power
supply, a single board computer, and a base station radio. The power supply is a medical
grade UL rated 120/240V AC power supply with on board overvoltage and overcurrent
protection. The single board computer is a PC 104 form factor running Linux operating
system. It provides a serial port for direct access. Additionally, it provides Ethernet
connectivity to allow data to be sent to the web portal. The base station radio collects all
incoming messages from the mesh network. There is an external antenna for the base
radio. It then passes this information to the computer. The computer then processes this
data eliminates duplicates and transmits via Ethernet. The gateway uses CompactFlash for
storage.

The gateway has two sets of status LED’s. One set is used to give status of the mesh
network. The second set is used to provide status of the computer and Ethernet
connectivity.

The gateway allows for bidirectional communication. The portal is capable of issuing
network commands to the gateway to assist in network management. Communication is
secure via SSL. Data is also encrypted for provide and additionally layer of security.
