Abstract:
A method for controlling a variable production line using a skid-type variable workbench and an apparatus for the same. According to the method, a process group including multiple variable workbenches may be organized based on a design, each of the multiple variable workbenches may be mounted on an upper part of a skid board, the skid board may be loaded on a powered line that moves at a regular speed in a fixed direction, the skid board may be moved in consideration of a position of a worker responsible for each process and a work state of the process group, and movement of a target variable workbench may be stopped by removing a skid board, on which the target variable workbench corresponding to an unload instruction in the process group is mounted, from the powered line when the unload instruction is input by a worker.
Abstract:
The present invention relates to controlling of an access for a device on home network middleware. The access control apparatus includes: an access control manager, a virtual device and a virtual device manager. The access control manager manages a list of authentication codes including an authorization level and authentication code for the device and a client requesting a service to the device; controls the access for the device by authenticating the client based on the list of authentication codes and checking whether the device control request is suitable for the authorization level of the client. The virtual device is generated in correspondence with the device to store device information and an encryption key required for encrypted communication with the device. The virtual device manager manages the virtual device corresponding to the device by checking the device periodically.
