Pwm. Tsang et Rwc. Wang, DEVELOPMENT OF A DISTRIBUTIVE LIGHTING CONTROL-SYSTEM USING LOCAL OPERATING NETWORK, IEEE transactions on consumer electronics, 40(4), 1994, pp. 879-889
The Local Operating Network is a technology that allows intelligent de
vices (or nodes) such as actuators and sensors, to communicate with on
e another through an assortment of communication media using a standar
d protocol. Both distributed and peer-to-peer communications are suppo
rted between the nodes in the network and a central control system or
a file server is not required. In addition, the relatively high data r
ate and the availability of routers permit large amount of nodes to be
tapped onto a network domain while at the same time maintain high com
munication efficiency. Consequently, it is suitable for developing low
-cost consumers and professional communication products that can be wi
dely applied in automating buildings, factories, vehicles, home and do
mestic, appliances. In this paper we have reported on the development
of a distributive control lighting system using the LON technology. Th
e nodes in the system (i.e. lamps, switches and the central control un
its) are tapped onto the network bus and are linked by logical binding
s instead of complicated hardwire connections. The system we have desi
gned is economical to build, easy to service, modify, and provides rel
iable communication between the lamps and the switches. These attracti
ve features demonstrate the feasibility of using LON in building distr
ibutive control networks, as well as the potential of our lighting sys
tem in practical applications.
