Title:
DRIVE CONTROL DEVICE AND DRIVE CONTROL SYSTEM COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2016/079910
Kind Code:
A1
Abstract:
According to an aspect of the present invention, provided is a drive control device for receiving, via an electric wire, a transmission signal generated by superimposing a plurality of control signals on power transmission voltage to control drive of a device to be controlled, wherein a detection frequency is set for the drive control device, one of the plurality of control signals is a control signal for controlling the device to be controlled, and the frequency thereof is close to the detection frequency. The drive control device is provided with: a drive voltage generation unit which generates a first drive voltage from the power transmission voltage of the transmission signal to drive the device to be controlled; a detection current generation unit which generates a detection current the frequency of which is the detection frequency; a magnetic element through which the detection current flows, and which generates an output corresponding to a result of multiplication of the detection current and a current flowing through the electric wire; and a signal processing unit which detects the control signal for controlling the device to be controlled from the output from the magnetic element, and controls the device to be controlled on the basis of the control signal.
