DIMMER TERMINAL EQUIPMENT FOR REMOTE MONITOR CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a dimmer terminal equipment of the remote monitor control system in which a dimmer fade time and a dimmer curve are set by a transmission signal. SOLUTION: A transmission unit sends a transmission signal to a dimmer terminal equipment 1 by using an object level of a dimmer level and a fade time changing the dimmer level as control data. The dimmer terminal equipment 1 uses a signal processing section 10 to receive the transmission signal via a transmission signal transmission reception section 7 and calculates a level control signal based on the current dimmer level, the control data and data of the dimmer curve stored in a nonvolatile memory 9. A dimmer control processing section 11 provides an output of a duty control signal controlling a duty ratio to a PWM signal output circuit section 14 via an insulation circuit section 12 based on the level control signal of the signal processing section 10 and the PWM signal output circuit section 14 modulates a pulse width of the PWM dimmer signal applied to a load circuit 2 based on the duty control signal.
