ARRANGEMENT FOR, AND METHOD OF, ACCURATELY LOCATING TARGETS IN A VENUE WITH OVERHEAD, SENSING NETWORK UNITS

摘要

Multiple sensing network units are deployed in a venue. Each unit includes an overhead housing, and supports a plurality of electrically-powered sensor modules for sensing targets in the venue, and for generating target data indicative of the targets. Each unit preferably also includes a network communications module. Each module is interchangeably mounted in the housing. A power and data distribution system transmits network control data and electrical power to the sensor modules, and transmits the target data away from the sensor modules.
