The invention relates to a small non-motor vehicle antitheft alarm device based on a RFID and belongs to the technical field of monitoring. The small non-motor vehicle antitheft alarm device comprises a RFID read-write door column, a one-way electric fence, an infrared sensor, a sound alarm device, an integrated single chip computer system, a power supply system, a solar power generating and storage and automatic rotating system. The RFID reader, the infrared sensor, the one-way electric fence and the sound alarm system are connected with the integrated single chip computer system. When an external power supply is connected, the power supply system supplies power to all the equipment. When the external power supply is not connected or power-off occurs, the solar power generating and storage and automatic rotating system supplies the power to all the equipment. The structure is simple, installing is convenient, the cost is low, energy saving and environmental protection are achieved, matching of people and a vehicle is achieved, and the situation that the non-motor vehicle is stolen is reduced.
