Abstract
The utility model relates to a circuit for implementing long-distance coincident code-free theft-proof alarm under the condition of rain or abnormal starting of motorcycle, comprising a sensor, a single-chip computer, a relay drive circuit and a regulation circuit. The utility model is characterized in that the rain signal and abnormal starting signal of the sensor is connected with the single-chip computer through a sensor interface. The output end of the single-chip computer is provided with the relay drive circuit. GSM emissive and receiving module is connected with the output end of the single-chip computer through a touch-calling dial drive circuit. The utility model has the advantages that alarm signal can be emitted when the motorcycle is under the condition of rain or abnormal starting. Because touch-calling dial program and the GSM emissive and receiving module are adopted, the alarm signal can be transmitted in a long distance through civil radio mobile communication network. The alarm signal can avoid coincident code so long as the cipher code of SIM card is memorized in the program of the touch-calling dial circuit.
