The database 10 has authority information 120 of workers stored therein. The authority information 120 of workers can include information regarding the identity of workers (identity information 110) and information regarding the electronic devices accessible by each worker (lists information 130).
The fool-proofing unit 30 can include an information input module 320 and a query module 310.
The information input module 320 is configured to collect information of an electronic device 50 and identity information 110 of a worker who requests signing in to use an electronic device 50.
The query module 310 is configured to search the database 10 based on the information of the electronic device 50 and the identity information 110 of the worker who issues a request, and then determines whether the worker has the authority required for operating the electronic device 50.
Specifically, the query module 310 communicates with the information input module 320. When a worker issues a request for signing in for the electronic device 50, the information input module 320 collects information of the electronic device 50 and identity information 110 of the worker, and sends the information to the query module 310. The query module 310 searches the database 10 based on the information of the electronic device 50 and the identity information 110 of the worker to determine whether the device 50 is one of the electronic devices listed in a lists information 130.
The controlling unit 40 is configured to power on a power source 520 of the electronic device 50 when the worker has the authority to sign in for the electronic device 50. The power source 520 can include electricity supply 5201 and air supply 5202. For example, if the device 50 is one of the electronic devices listed in a lists information 130, the device 50 can be operated by the worker who issues a request for signing in for the electronic device 50, and the controlling unit 40 can power on the electronic device 50.
The system 100 for controlling access to electronic devices can further include an upper server 20. The fool-proofing unit 30 and the controlling unit 40 can be located in the electronic device 50. The database 10 communicates with the upper server 20, and the fool-proofing unit 30 communicates with the upper server 20. For example, the fool-proofing unit 30 can communicate with the upper server 20 through a network and search the database 10 through the upper server 20.
In at least one exemplary embodiment, the system 100 for controlling access to electronic devices can further include a plurality of identity authentication terminals (not shown) distributed to workers. The information input module 320 is configured to read the identity authentication terminals to collect identity information 110 of a worker. The identity authentication terminals can be an office identification card. In an exemplary embodiment, when an identity authentication terminal is placed on an electronic device 50, the electronic device 50 can be powered on, and when the identity authentication terminal is taken away from the accessible electronic device 50, the electronic device 50 is powered off.
The controlling unit 40 can be a fool-proofing box connected between the fool-proofing unit 30 and the power source 520 of an electronic device 50. The fool-proofing box controls the power source 520 to turn on when a worker has the authority to sign in for the electronic device 50.
In at least one exemplary embodiment, the system 100 for controlling access to electronic devices can further include a recording unit 510. The recording unit 510 is configured to collect and store information of workpieces loaded on or processed by the electronic device 50. The recording unit 510 can communicate with the fool-proofing unit 30.
The recording unit 510 collects information of a workpiece after the electronic device 50 is powered on and the workpiece is loaded on the electronic device 50. The fool-proofing unit 30 generates a process record based on the information of the electronic device 50, the identity information of the worker, and the information of the workpiece. The process record can be stored to track manufacturing procedures of a workpiece, which can be processed by the electronic device 50.
The database 10 can be further configured to store information of the workpieces in advance. The system 100 further includes an identifier attached to each of the workpieces. The identifier is associated with the information of a workpiece. The recording unit can collect information of a workpiece by reading the identifiers. For example, the identifier can be one- or two-dimensional barcode, and the recording unit 510 includes a barcode scanner to read such barcodes.
S101: establishing a database that stores authority information of workers. The authority information of workers can include identity information of the workers and lists information of accessible electronic devices corresponding to each worker.
S103: determining if there is a request for signing in an electronic device. When there is a request for signing in an electronic device, the method proceeds to step S105, otherwise no response is made by the electronic device.
