Title:
CHILD STATION AND SIGNAL TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/188298
Kind Code:
A1
Abstract:
A child station 2 comprises: four input terminals; a first sensor device that has four first conduction circuit units respectively associated with the four input terminals and that has such a circuit configuration that a current flows through an i-th one of the first conduction circuit units and no current flows through the first conduction circuit units other than the i-th one; a second sensor device that has four second conduction circuit units respectively associated with the four input terminals and that has such a circuit configuration that a current flows through a j-th one of the second conduction circuit units and no current flows through the second conduction circuit units other than the j-th one; and a control device that detects a state in which currents flowed through the i-th one of the first conduction circuit units and through the j-th one of the second conduction circuit units, thereby determining that a power supply line P+, a power supply line P0, a signal line D+, and a signal line D− are connected to the input terminals.
