The utility model relates to a three -dimensional circulation formula garage parking electric control system, converter, brake device, incremental encoder, radio frequency reader, touch -sensitive screen, photoelectric switch, vortex proximity switch and the scram switch be connected by PLC, with PLC read passive RFID tag through radio frequency reader, connect AC asynchronous motor through the converter, act on the output shaft through brake device. System integral control function is perfect, the simple operation, motor closed loop feedback control guarantees that the system steadily add to slow down and stop, radio frequency and vortex proximity switch are not only accurate sensitive, prevent in addition that nonmetal thing shelters from, system's operation reliably, photoelectric switch's frame rotational path obstacle detection, the emergency braking of scram switch and the measuring of sliding unusually of encoder have ensured support of the people thing safety.
