System principle

In the software, the electrical plane layout and tree structure diagram of Shuikou Power Station are pre-written and solidified in the computer software. Staff can easily implement user management, user operations (including quick authorization, task authorization and temporary authorization), record browsing and other operations through a good interactive graphical interface.

When the staff starts the system, they can perform quick authorization, task authorization or temporary authorization after password identification. When using "quick authorization", the system sends all the unlocking authority of the user to the smart key at one time, and the staff can use the smart key to unlock; when using "task authorization", the system assigns the authorized unlocking scope selected by the staff After it is sent to the smart key, the staff can use the smart key to unlock; when the operator needs to temporarily expand the scope of work during on-site operations, he only needs to notify the staff to use the "temporary authorization" function on the host computer software.

During the operation, the smart key automatically detects the identity of the smart lock, and the operator inserts the smart key into the corresponding lock, and checks whether the operation object is correct through its coding head. If it is correct, the smart key will issue a command to allow the operation by voice, and at the same time open its locking mechanism, at this time the unlocking operation can be performed. If the wrong interval or operation is wrong, the smart key will issue an error warning by voice, and at the same time, the smart lock cannot be operated to achieve the purpose of forced locking. The operator receives good training while receiving reliable security, which reflects the "second guardian". role. After the operation is completed, the smart key will report the switching operation information to the management host for storage through the transmission/charging stand, so that the management personnel can check and assess.
