Description

TECHNICAL FIELD [0001] The present invention relates to a security management apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an access security management apparatus, and more particularly, to an access security management apparatus capable of replacing a service provider main level installed in an unmanned substation.

The access control system in the unmanned substation consists of a card reader, an RTU (Remote Monitoring and Control Measuring Device), a service provider master device, and an AIU device interlocked with the ACU. The operation principle of the system is as follows.

First, in case of security setting, if the security button of the access controller is pressed, check the closed state of the front door and the front door, and then ask the service supplier for confirmation of the abnormality of the sensor. Then, the service provider's master confirms the detector status, and if it is determined to be normal, performs the security of itself and sends the security setting contact to the access controller. Next, the access controller requests the security setting by dividing the transmitted contact 1: 3 (access controller, RTU, AIU device).

In case of unsecured security, if the administrator contacts the card reader connected to the access controller, it confirms the validity of the employee card and requests the security clearance by the service provider. Next, the service provider master sends the security release contact to the access controller after the security is canceled. Then, the access controller requests 1: 3 division of the transmitted contact (access controller, RTU, AIU device) to release the security.

The above-mentioned access control system is different from the method of connection of the equipment connected to each other according to the site condition and the security company due to the lack of standardization of the service master's standard value. Therefore, every time the service company changes, the dismantling and installation are repeated, resulting in the loss of security function during the time, and it is necessary to check the interlocking function of the access control system when replacing the field device.

In this regard, Korean Patent Laid-Open Publication No. 2005-0020388 discloses a " security zone access control method and system ".
