Abstract
The utility model relates to the technical field of alarms, particularly to an anti-theft alarm for an electric motorcar. The phase line detecting circuit of the anti-theft alarm for the electric motorcar is connected with a vibration detecting circuit connected with a microprocessor; the input terminal of the phase line detecting circuit is connected with a resistor R18 of which the other end is connected with a resistor R24 and a capacitor C33, and the other end of the capacitor C33 is connected with the input terminal of a vibration detecting amplifier. The anti-theft alarm for the electric motorcar can save the limited charge capacity of the electric motorcar by utilizing the vibration and the phase line detecting circuit to detect the state of the whole electric motorcar and send a 125K signal selectively, and does not start the identification signal until the detection of the vibration and the phase line detecting circuit shows that the electric motorcar is immobile, thereby ensuring the vividness and order of the transmitted signal.
