Abstract:
A communicating method between a master and a slave connected through a belt connected to a gripper-unit in a hoist device of a rail car, and to technology in which the master and the slave perform power line communication through a power supply line for supplying power formed in a belt, thereby more stably transmitting and receiving signals in a simple system structure.

Claim (Index 1):
A communicating method between a master communication device and a slave communication device for controlling a gripper-unit in a hoist device of a rail car, in which the master communication device connected to a rail car controller and the slave communication device connected to the gripper-unit are connected through a belt to operate the gripper-unit in accordance with a control signal of the rail car controller, thereby performing a hoist work, the communicating method comprising:\n a first step in which the master communication device provides power supplied from the rail car controller to the slave communication device through a power supply line formed in the belt, and the slave communication device supplies the power provided from the master communication device to the gripper-unit; a second step in which the master communication device modulates the control signal provided from the rail car controller, overlaps the modulated control signal with power, and transmits the modulated control signal overlapped with the power to the slave communication device through the power supply line, and the slave communication device transmits a signal including a response to a control signal to the master communication device through the power supply line formed in the belt; and a third step in which the master communication device or the slave communication device compares voltage of the signal received through the power supply line with preset reference voltage to determine a communication state through the power supply line, and when it is determined as a communication abnormality state, communication abnormality state information is provided to the rail car controller through the master communication device.
