Electric blanket single-chip microcomputer control circuit

The utility model relates to a circuit and especially to an electric blanket single-chip microcomputer control circuit. The electric blanket single-chip microcomputer control circuit is characterized in that an electric blanket heating wire, the first electrode and the second electrode of a bidirectional silicon controlled rectifier are connected in series and then are connected with the input end of a 220 power supply; the eleventh pin of a single-chip microcomputer AT89C2051 is connected with the base electrode of a triode through a fourth resistor; and the collector electrode of the triode is connected with the control electrode of the bidirectional silicon controlled rectifier through a fifth resistor. By means of the above technical scheme, the electric blanket single-chip microcomputer control circuit has an advantage and beneficial effect of good safety and practicality.
