The invention discloses a logistics warehouse access control system based on an RFID technique. The logistics warehouse access control system comprises an RFID label, an RFID reader, a door lock device, a door lock controller and an access control platform, wherein the RFID label is used for being carried by a worker, the door lock device is mounted on a door, and the door lock controller is used for controlling the door lock device to open or close the door. The RFID label is not internally provided with a power supply, and can acquire energy from an electromagnetic field of the RFID reader in a working process; furthermore, the RFID label is light, small in volume, very long in service life and very low in cost, is not influenced by the ambient environment, is not polluted by greasy and dust, can be read and written without a light source and is high in recognition speed, large in data capacity and convenient to widely generalize and use; and manual intervention is not required in a recognition process, a read-only function and a write-in function can be simultaneously realized, read-in label data can be modified, the write-in time is short, a password protection function can be set, and information of all people visiting a warehouse can be recorded, so that intelligent access control is realized, and the warehouse management efficiency is greatly improved.
