A system for collecting time division data through a single cable is provided to divide and process a synchronization signal, a driving power, and data from a pulse signal transmitted through a single cable. A system for collecting time division data through a single cable includes a data collecting device(20) collecting measured values of a sensor corresponding to a plurality of time slots after decoding the time slots received through a single cable. An encoder(30) is connected to the data collecting device with a single cable to extract a synchronization signal and a driving power from a pulse signal transmitted from the data collecting device. The encoder adds data detected by each sensor to the corresponding time slot in order to transmit to the data collecting device. The data collecting device includes a band pass filter(21) passing a predetermined high frequency band in signals applied from the single cable. A data collecting unit(23) collects data after removing a carrier frequency by filtering the predetermined high frequency signal through a low frequency filer.
