Variable channel type access system

The invention provides a variable channel type access system adopting a new parking lot structure as well as a parking access and warehouse cargo access structure and mode. The system comprises a parking lot (or a warehouse), movable devices, parking space frames (or trays), guide rails, a license plate recognizer (or a cargo recognizer) and a control center. According to the system, parking spaces are divided into matrixes connected closely (shelves are arranged into closely adjacent rows); due to application of variable channel design, the number of channels is reduced greatly; especially for medium and large parking lots (or warehouses), lots of parking spaces (or cargo storage positions) can be increased, and vehicles are parked (or cargoes are stored and taken) through the movable devices on the guide rails; and manual operation is not required, and the sizes of the parking spaces are reduced greatly, so that the number of the parking spaces is increased greatly. Through guide rail design of the system,
