Abstract
The utility model relates to a protection system for power voltage detection. The protection system comprises a power voltage detecting circuit, an A/D data converting circuit, a central processor circuit and a ZigBee wireless alarm module circuit. An output signal of the power voltage detecting circuit is sent to the central processor circuit via the A/D data converting circuit. An output signal of the central processor circuit is sent to the ZigBee wireless alarm module circuit. According to the protection system, the power voltage detecting circuit is used to collect an overvoltage or undervoltage signal of mains voltage, and then the ZigBee wireless alarm module circuit sends alarm information to an alarm center after identification of the central processor circuit, and thus the early-stage condition of a fire hazard is detected, and an alarm is sent timely to prevent fire hazards.
