Benefits of technology

The present invention provides a method for RF communication between an automated guided vehicle and manufacturing equipment in an automated material handling system. The method involves adding smart modules to both the vehicle and equipment communication units. The initial setting information for RF communication is transmitted and received through the modules to create an RF communication environment. This allows for easy replacement of the communication units in the system without the need for extensive modifications. The technical effect is an improved RF communication solution for automated material handling systems.

Problems solved by technology

In the practice of the communication using this way, there is a disadvantage in that communication units between an unmanned transporting device and a manufacturing equipment should be installed in close proximity as possible.
Also, it has difficulty in the beauty and management inside the plant.
Moreover, since it sends and receives the communication without the generation of a unique ID, the communication interference between adjacent communication devices can be generated due to the optical noise.
Accordingly, there are problems in that a lot of time and cost and an inconvenience of a user are involved.
