A pipe freezing prevention system is provided to make installation easy and to minimize the cost required for installation by operating a relay unit for operating an anti-freezing heating wire and controlling many anti-freezing heating wires selectively with a single control system, and transmitting and receiving data between a control indication unit and a detection operation unit with a single wire or a wireless method. A pipe freezing prevention system comprises a sensor unit(20) composed of a sound sensor sensing sound according to the flow of fluids in a pipe and checking the flow of fluids and a temperature sensor measuring temperature of a pipe, a detection operation unit(30) comparative-operating the sensed value of the sensor unit into digital data value and sending out signals of a selected channel to the outside, a control indication unit(40) receiving the signals from the detection operation unit through the selected channel of many channels and operating a relay unit accordingly, indicating the state of an anti-freezing heating wire, the sensor unit and the detection operation unit and letting a user control a system, and an anti-freezing heating wire(10) installed to the pipe to heat up a pipe with power supplied from the outside by operating the relay unit of the control indication unit. |
