Accordingly, in the present invention, one of the plurality of locking devices 110 to 130 (in particular, the locking device 110 coupled to the frontmost door of the switchgear is used as a main locking device and the remaining locking devices 120 and 130 are used as a sub- So that the remaining locking devices 120 and 130 are temporarily opened by opening the main locking device 110. That is, when one locking device 110 is opened, the remaining locking devices 120 and 130 are automatically opened This eliminates the need for the operator to open the locks on his / her own route in order to reach the desired work space.

2 is a block diagram illustrating an integrated lock management apparatus for a switchboard according to an embodiment of the present invention.

The lock integrated management device 200 of the switchboard of FIG. 2 is an apparatus applied to a switchboard having a plurality of lock devices as shown in FIG. 1, which includes a plurality of lock devices 110 to 130, A power supply unit 210, an unlocking information obtaining unit 220, a controller 230, a data input / output unit 240, and a plurality of alarms and status indicators 251 to 253.

The bus voltage detection and operation power supply unit 210 senses and notifies the voltage of a power source charged in the bus and generates and supplies drive power necessary for driving the integrated lock management apparatus 200 using the bus line voltage.

The unlocking information obtaining unit 220 obtains the unlocking information for opening or closing the locking device input from the user or the external device.

The unlocking information obtaining unit 220 of the present invention may include a keypad 221 having a plurality of key buttons capable of inputting unlocking information, a fingerprint input unit 220 for inputting fingerprint or body information of an operator requesting opening of the main locking unit 110, A key reader 223 for reading and outputting the unlock information stored in the key device, a lock stored in a tag built in the mobile device of the access card or the worker, A tag reader 224 for reading and outputting the release information, a communication module for establishing a communication channel with the operator's mobile device or the power supply and distribution control device, and acquiring and outputting the lock release information transmitted from the mobile device or the power- (225), which allows an operator to provide information (210) for unlocking the lock (110) in various forms .

The control unit 230 basically closes all the locking devices 110 to 130 when the bus voltage is applied to ensure the safety of the operator and the safety of the equipment. However, even if the bus voltage is applied, the lock devices 110 to 130 are opened in response to the input of the unlocked information previously registered through the lock release information obtaining unit 220. [

In particular, the controller 230 of the present invention stores information on unlocking information that allows the main locking device 110 to be opened, and compares the unlocking information obtained through the unlocking information obtaining unit 220 with a comparison / analysis result So as to determine whether the main locking device 110 is opened or not. When the main locking device 110 is normally opened, the sub locking devices 120 and 130 are further opened so that the worker can freely move all the work spaces in the sub-locking device 120 without performing any unlocking operation to the remaining sub locking devices 120 and 130 Allows you to perform the tasks you need.

Meanwhile, if necessary, the control unit 230 of the present invention sets a difference in the openable work space according to the work right as shown in Table 1 below, thereby preventing the worker from performing work without his / do. At this time, the task authority may be classified according to the unlocking information, or may be classified according to the worker information inputted together with the unlocking information.

Task permissions Input information Open space One Unlock information 1
Unlock information + operator information 1 sec1, sec2, sec3 2 Unlock information 2
Unlock Information + Worker Information 2 sec1, sec2 3 Unlock Information 3
Unlock Information + Worker Information 3 sec1

In addition, when the main locking device 110 is closed, the controller 230 checks whether all of the sub locking devices 120 and 130 are normally closed and then closes the main locking device 110 again. Thus, The main locking device 110 is prevented from being locked by an outside person.

In addition, the controller 230 controls the locking device such that when the busbar is opened in a state in which the busbar voltage is applied, when the locking device is opened without inputting the unlocking information, when the locking device is opened through breakage of the locking device, If it is detected, an alert operation is immediately performed or a warning alert message is generated and transmitted to a predetermined contact (e.g., telephone number, e-mail, web page, etc.).

In addition, it collects and stores information on the operation state of the control unit 230 (for example, the open / close history of the locks 110 to 130, the alert occurrence history), and provides the obtained information to the mobile device or the power- Let's do it.

The data input / output unit 240 includes a monitor, a button, a scroll button, an instrument panel, and the like. The data input / output unit 240 inputs various requests of the operator or audibly informs the operator of the operation status of the switchboard and the controller 230.

Each of the plurality of alarms and status indicators 251 to 253 is disposed adjacent to the plurality of lock devices 110 to 130 and controls the opening and closing of the lock devices 110 to 130 disposed adjacent thereto under the control of the controller 230 . That is, the operator can easily identify the lock devices 110 to 130 with the naked eye through the plurality of alarms and status indicators 251 to 253.

FIG. 3 is a view for explaining a method of unifying integrated management of a switchboard according to an embodiment of the present invention, which relates to a method of opening a lock device.

First, the busbar voltage applied to the switchboard is sensed (S1). If the busbar voltage is not applied (S2), immediately after entering the step S7, an open command for the main lock device 110 is generated (S7) (S8, S9) so as to issue a batch opening command to the sub locking devices 120 and 130 only when the main locking device 110 is normally opened.

On the other hand, when the bus line voltage is applied, the closed state of the main locking device 110 and the sub locking devices 120 and 130 is maintained. However, when the unlocking information for opening the locking device is input by the worker, the mobile device of the worker, or the power supply and distribution control device (S3), the controller 230 compares the acquired unlocking information with the previously registered unlocking information It is determined whether the main locking device 110 is opened (S4), and at the same time, the current operation mode is confirmed (S5).

When the operation mode of the lock integrated management device of the switchboard is in the batch release mode (S6), after the open command of the main lock device 110 is generated (S7), the main lock device 110 confirms the operation mode (S8, S9), the sub-lock apparatuses 120, 130 are instructed to release a batch release command only when they are normally opened.

On the other hand, if the operation mode of the lock integrated management device of the switchboard is not the unbundle open mode (S6), the operation mode of the worker who has requested the lock device opening operation at present based on the type of the unlocking information, After confirming the authority, the worker is allowed to grasp the accessible work space (S10). Subsequently, when an open command of the main locking device 110 is issued (S11), only when the main locking device 110 is normally opened, a sub lock device (for example, 120 (S12, S13).

FIG. 4 is a view for explaining a method of integrated management of locking of a switchboard according to another embodiment of the present invention, which relates to a method of closing a locking device.

First, whether or not the busbar voltage to the switchboard is applied is detected (S21). If the busbar voltage is applied (S22), all lock devices are closed all at once (S23).

On the other hand, if the bus voltage is not applied (S22), the locking devices 110 to 130 are sequentially closed through the following steps (S24 to S29). That is, when a closing command is inputted by the worker, the operator's mobile device, or the powerhouse control apparatus (S24), the controller 230 monitors the statuses of the sublocks 120 and 130 (S25) It is first checked whether all the switches 120 and 130 are in a closed state (S26).

If both of the sub-locking devices 120 and 130 are closed, the main locking device 110 is also immediately closed (S28). Otherwise, the sub-locking devices 120 and 130 are in the open state, 110) is not allowed to be closed, and waits until both of the sub locking devices 120, 130 are closed (S29).
