Electric engineering machinery alarm control circuit and electric engineering machinery

The utility model relates to an alarm control circuit, and provides an electric engineering machinery alarm control circuit and an electric engineering machinery in order to solve the problem that alarm information is not given out when the existing engineering machinery works, so that the alarm is not timely. The alarm control circuit of the electric engineering machinery comprises an alarm, a driving power supply, a starting switch of the electric engineering machinery connected with the driving power supply, and a normally open relay, a starting gear wiring terminal of the starting switch is connected with a coil of the relay in series, and the driving power supply is connected with the alarm in series through a contact of the relay. According to the utility model, when the starting switch is in a starting gear, the coil of the relay is electrified, and the contact of the relay is closed, so that the alarm works to generate a sound-light alarm signal, personnel around the machine can perceive the state of
