이와 같이 구성되는 본 발명에 의한 램데이타비상소거장치의 동작을 설명한다.The operation of the RAM data emergency erase device according to the present invention configured as described above will be described.

먼저 외부전원(Vcc)으로부터 정상적으로 전원이 공급되는 경우, 상기 전원공급부(100)에서는 외부전원(Vcc)을 온(on)되어 있는 상기 램데이타소거스위치(130)를 통해 상기 램(140)으로 공급하게 된다.First, when power is normally supplied from an external power supply (Vcc), the power supply unit 100 supplies the power supply unit 100 to the RAM 140 through the RAM data erase switch 130 which is turned on. Done.

또한, 외부전원(Vcc)으로부터의 전원공급이 중단되면 전원공급부(100)에서의 비상전원(120), 즉 배터리로부터 공급되는 전원을 램데이타소거스위치(130)를 통해 상기 램(140)으로 공급하게 된다.In addition, when the power supply from the external power supply (Vcc) is stopped, the emergency power supply 120, that is, the power supplied from the battery, is supplied to the RAM 140 through the RAM data erase switch 130. Done.

즉, 상기 비상전원공급스위치(110)가 온(on)되어 있어서, 상기 비상전원 (120)이 상기 비상전원차단스위치(110)와, 상기 전원공급부(100)와, 온(on)되어 있 는 램데이타소거스위치(130)를 통해 상기 램(140)으로 공급되는 것이다.That is, the emergency power supply switch 110 is turned on, so that the emergency power supply 120 is turned on with the emergency power cutoff switch 110, the power supply unit 100, and the power supply unit 100 is turned on. It is supplied to the RAM 140 through the RAM data erase switch 130.

상기 비상전원차단스위치(110)는 관리자의 의도적인 전원 차단을 위한 스위 치로, 비상전원(120)을 단속 ,즉 연결 또는 차단하는데 이용된다. 평소에는 비상전 원(120)과 전원공급부(100)가 비상전원차단스위치(110)의 온(on)동작으로 항상 연 결되어 있다가 관리자가 상기 케이스를 개방하지 않고 상기 스위치버튼구멍을 통하 여 핀셋 등으로 비상전원차단스위치(110)를 눌러 주어 오프(off)시킴으로써 비상전 원(120)으로부터의 전원공급을 차단함으로써 램(140)에 저장된 데이타를 소거시킬 수 있다.The emergency power cutoff switch 110 is a switch for intentionally shutting off the power of the manager, and is used to interrupt, that is, connect or cut off the emergency power source 120. Usually, the emergency power 120 and the power supply unit 100 are always connected by the on operation of the emergency power cutoff switch 110, and the manager does not open the case, and the tweezers is opened through the switch button hole. By pressing and turning off the emergency power cutoff switch 110, the data stored in the RAM 140 can be erased by cutting off the power supply from the emergency power source 120.

이때, 장치가 외부에서 전원을 공급받음으로써 정상적으로 동작하고 있는 상태에서는, 관리자가 실수로, 또는 허가받지 않은 비인가자가 악의로 비상전원차단스위치(110)를 눌러서 오프(off)시켰을 때 비상전원(120)만이 차단되므로, 외부전원(Vcc)에 의해 램(140)으로 전원공급이 됨으로 데이타 소거는 이루어지지 않는다.At this time, in a state in which the device is operating normally by receiving power from the outside, when the administrator accidentally or unauthorized unauthorized person presses the emergency power cut-off switch 110 to turn off the emergency power 120 Since only) is cut off, power is supplied to the RAM 140 by the external power supply Vcc, and thus data is not erased.

한편, 관리자가 의도적으로 필요에 의해 램(140)의 전원을 차단하기 위해서는 외부로부터 공급되는 전원(Vcc)을 차단한 후, 비상전원차단스위치(110)를 오프(off)시키면 된다 즉, 외부전원(Vcc)을 차단하고 비상전원공급스위치(110)를 오프(off)시키면 상기 전원공급부(100)에 전원이 공급되지 않아 상기 램(140)에 전원이 공급되지 않게 되어 데이타 소거가 이루어진다.On the other hand, in order to cut off the power supply of the RAM 140 intentionally necessary, the administrator may cut off the power supply Vcc supplied from the outside, and then turn off the emergency power cutoff switch 110. When the Vcc is blocked and the emergency power supply switch 110 is turned off, power is not supplied to the power supply unit 100, so that power is not supplied to the RAM 140, thereby erasing data.

또한, 비인가자의 불법 접근을 위해 상부케이스를 개방할 시에는 상기 전원공급부(100)로부터 상기 램(140)으로 공급되는 전원을 상기 램데이타소거스위치(130)가 오프(off)됨으로써 차단하게 된다. 즉, 불법침입자가 상부케이스를 파괴하거나 강제로 열게 되면 상기 상부케이스의 스위치누름부에 의해 눌러져 온(on) 상태에 있던 램데이타소거스위치(130)가 상기 스위치누름부에 의해 눌러지지 않게 되므로 오프(off)되어 상기 램(140)으로 공급되는 전원을 차단함으로써 상기 램(140)에 저장된 데이타가 소거되도록 한다.In addition, when the upper case is opened for illegal access by unauthorized persons, the RAM data erase switch 130 is cut off by turning off the power supplied from the power supply unit 100 to the RAM 140. That is, when the illegal intruder destroys or forcibly opens the upper case, the RAM data erasing switch 130, which is in an on state pressed by the switch pressing portion of the upper case, is not pressed by the switch pressing portion. The data stored in the RAM 140 is erased by turning off the power supplied to the RAM 140.

즉, 상기 램데이타소거스위치(130)는 램이 내재된 케이스를 강제로 열거나 파괴하여 램에 저장된 데이타에 접근하려고 하면 외부전원(Vcc)으로부터 전원이 공급되거나 비상전원(120)으로부터 전원이 공급되거나 상관없이 모두 램(140)으로 공급되는 전원을 차단하여 램(140)에 저장된 데이타를 소거하게 된다. 이것은 불법 침입자에 의한 접근이 발생할 경우에는 어떤 경우라도 램으로 공급되는 전원을 차단시켜 램(140)에 저장된 데이타가 소거되도록 하기 위해서이다.That is, when the RAM data erasing switch 130 tries to access data stored in the RAM by forcibly opening or destroying the case in which the RAM is embedded, power is supplied from the external power source Vcc or power is supplied from the emergency power source 120. Regardless of whether or not, all of the data stored in the RAM 140 are erased by cutting off the power supplied to the RAM 140. This is to prevent the data stored in the RAM 140 by erasing the power supplied to the RAM in any case when the access by the illegal intruder occurs.

이상에서 설명한 바와 같이 본 발명에 의한 램데이타비상소거장치는 외부전원과 내장 배터리와 같은 비상전원을 선택하여 램으로 공급하는 장치에 있어서, 램의 불법 접근을 위해 보안 장비 등의 케이스를 개방시 이를 감지하여 램의 전원을 차단함으로써 램에 저장된 기밀 정보를 소거하거나, 관리자가 필요에 의해서 램 내의 기밀 정보를 소거할 경우 외부전원을 내리고 비상전원차단스위치를 오프(off)시킴으로써, 기밀 정보의 외부 유출을 막는 효과가 있다.As described above, the RAM data emergency erase device according to the present invention selects an emergency power source such as an external power source and an internal battery and supplies the same to the RAM. Detects confidential information stored in RAM by detecting the power off of the RAM by detecting it, or turns off the external power and turns off the emergency power cutoff switch when the administrator erases the confidential information in the RAM as necessary, It is effective to prevent.
