Controlling communication system

摘要

There is provided a controlling communication system which includes a control device for transmitting a control signal, an object-side communication device mounted on a controlled object for receiving the control signal, and a drive control device for controlling the controlled object, and which can set a failsafe function of the object-side communication device using the control device, wherein a voltage reference value and a detection time reference value set by the control device are transmitted to the object-side communication device and are stored in a memory unit of the object-side communication device, and wherein the object-side communication device judges if the battery state meets a requirement for activating a failsafe function by referring to the voltage reference value and the detection time reference value stored in the memory unit.

主权项

1. An object-side communication device (4) used in a controlling communication system (1), the controlling communication system (1) including a control device (2) arranged to transmit a control signal and a drive control device (5) arranged to perform drive control of a controlled object (3), the object-side communication device (4) being mounted on the controlled object (3) and being arranged to receive the control signal,
characterized in that the object-side communication device (4) comprises a voltage detection unit (23) arranged to detect a power-supply voltage, an object-side receiving unit (22) arranged to receive a signal containing a detection time reference value used for activation of a battery failsafe function, an object-side memory unit (21) arranged to rewritably store the detection time reference value, and an object-side control unit (20) arranged to compare the power-supply voltage with a voltage reference value and output to the drive control device (5) a failsafe signal instead of the control signal if the power-supply voltage is lower than the voltage reference value continuously for a period of time equal to or longer than the detection time reference value.
