The invention discloses a low-power-consumption automatic identification technology and parking space locking identification management technology based on a wireless technology, and through signal intensity of a wireless transmission technology, existence of a terminal is identified and distance of the identified terminal is marked, automatic identification of the terminal is simulated through recorded latest wireless signal historical data and action is executed, thereby achieving the purpose of automatically identifying the terminal. The main application occasions include automatic identification of parking space locks (i.e., automatic unlocking when a vehicle comes, and automatic locking when the vehicle leaves), application of ''electronic license plates'' in parking space integrated management, locking and automatic identification management of other devices and the like. A system mainly includes an automatic identification terminal and identified container/equipment, wherein the automatic identification terminal includes an identification unit and another control unit (an MCU), and the identified container/equipment includes an identified unit and another control unit (an MCU), etc.
