For example, without departing from the scope of the present invention, the second component may be referred to as a first component, and similarly, the first component may also be referred to as a second component.

1 is a view showing a repeater equipped with a security management module according to the present invention. Referring to FIG. 1, as usual, a mobile communication repeater is installed between a base station 200 for a mobile communication service and a mobile communication terminal 300 on a user side to relay a mobile communication signal.

At this time, the repeater housing 100 of the mobile communication repeater is provided with a security management module 110. The security management module 110 may be installed inherently in the repeater, or may have a module structure installed in addition to the repeater already installed. For example, the security management module 110 of the example described later is added to the outside of the pre-installed repeater housing 100 to manage security of the mobile communication repeater.

2 is a block diagram illustrating a security management module according to the present invention. Referring to FIG. 2, the security management module 110 may include a microcontroller (hereinafter referred to as “MCU”, 120), a separation signal generator 130, a repeater interface unit 140, a GPS module 150, and a power supply unit 160. ), An internal battery 170, a transceiver 180, and an antenna 190.

The power supply unit 160 receives power from the repeater and supplies power required for each component of the security management module 110. In addition, the security management module 110 is provided with a built-in battery 170 to supply power to ensure the operation of the security management module 110 when the repeater power supply is bad or power failure, as well as the security management module 110 from the repeater If disconnected, supply power to send disconnection signal to remote place.

3 is a circuit diagram illustrating a power supply voltage supply circuit in the present invention. Referring to FIG. 3, the power supply unit 160 may include a regulator 161, a backflow prevention diode 162, a power supply voltage output unit 163, a charging unit 164, a power switching device 165, and a voltage detector 168. It includes, and manages the charge and discharge of the built-in battery 170.

The regulator 161 is connected to the repeater power supply terminal to output the power applied from the repeater to a constant voltage (for example, DC 5V ~ 12V) of a predetermined size. The backflow prevention diode 162 prevents backflow of electrical energy to the regulator 161. The power supply voltage output unit 163 generates a voltage required by each component of the security management module 110 and outputs the generated voltage to the power supply voltage terminal VCC. The charging unit 164 generates a charging voltage necessary to charge the built-in battery 170 by using the output of the regulator 161.

When the output voltage of the regulator 161 is greater than or equal to a predetermined voltage (for example, 4.7V), the voltage detector 168 may be connected to the output voltage of the regulator 161 at the gate terminal G of the P-channel power FET, which is the power switching element 165. By supplying the same "H" level voltage to turn off the P-channel power FET, the electrical energy of the built-in battery 170 is prevented from being discharged. When the output voltage of the regulator 161 is less than 4.7V, the "L" level voltage ( For example, the P-channel power FET is turned on by supplying 0V to discharge electric energy of the internal battery 170.

When the power of the repeater is normally applied from the repeater power supply terminal, the power supply voltage is output through the regulator 161, the backflow prevention diode 162, and the power supply voltage output unit 163, and the charging unit 164 Through the built-in battery 170 to charge.

Then, when the security management module 110 is disconnected from the repeater power supply terminal or the repeater power is cut off, the regulator 161 and the charging unit 164 stop operation, and the voltage detector 168 applies the "L" level voltage. By outputting and turning on the P-channel power FET, the electric energy of the built-in battery 170 is discharged through the power supply voltage output unit 163.

4 is a circuit diagram illustrating a circuit configuration of a separation signal generation unit in the present invention. As shown in the illustrated example, a first connector 112 is connected to the repeater enclosure 100, and a second connector 114 is connected to the separation signal generator 130. The first connector 112 and the second connector 114 are electrically and physically detachably coupled to each other, and have three corresponding terminals.

The first terminal a1 of the first connector 112 is grounded to the repeater enclosure 100 through a conductive line. The second terminal b1 and the third terminal c1 are connected to each other by a conductive line. The second connector 114 is a connector on the side of the separation signal generator 130, and includes first to third couplings corresponding to the first to third terminals a1, b1, and c1 of the first connector 112, respectively. The terminals a2, b2 and c2 are provided. The third terminal c2 of the second connector 114 is grounded.

The separation signal generator 130 detects whether the security management module 110 is separated from the mobile communication repeater, and generates a separation signal at the time of separation. The separation signal generator 130 may detect a separation state in various ways such as separation from a repeater power supply, separation from the repeater enclosure 100, and separation between connectors.

Referring to FIG. 4, the separation signal generation unit 130 detects separation from the repeater power terminal and detects separation from the power separation signal generation unit 131 and the repeater enclosure 100 generating a power separation signal. An enclosure removal signal generation unit 133 for generating a removal signal, and a connector separation signal generation unit 135 for generating a connector separation signal by detecting that the first connector 112 and the second connector 114 are separated from each other. It is composed.

The power split signal generator 131 includes voltage divider resistors R11 and R12 for dividing a voltage applied from a repeater power terminal, and a capacitor C1 connected to the resistor R12 in parallel to maintain voltages at both ends. In the normal operation, the power disconnect signal S Bat maintains the "H" level by the voltage between the both ends of the resistor R12 applied from the repeater power supply terminal.

On the other hand, when the security management module 110 is disconnected from the repeater power supply terminal, the battery disconnect signal (S Bat) transitions to the "L" level.

The enclosure removal signal generator 133 is disposed between the first PNP transistor Tr1 and the base terminal of the first PNP transistor Tr1 and the ground disposed between the power supply voltage terminal VCC and the ground generated by the power supply unit 160. It includes a first diode (D1) coupled. In the normal operation, the base terminal of the first PNP transistor Tr1 includes the first diode D1, the first terminal a2 of the second connector 114, and the first terminal a1 of the first connector 112. Since the first PNP transistor Tr1 is turned on through the ground side of the vehicle body, the housing removal signal S Trap maintains the “H” level.

On the other hand, when the conductive line connected to the first terminal a1 of the first connector 112 is disconnected from the repeater housing 100, the first PNP transistor Tr1 is turned off and thus the enclosure removal signal S Trap is “L”. "Transition to the level.

The connector disconnection signal generator 135 may include a second PNP transistor Tr2 disposed between the power supply voltage terminal VCC and ground, and a second diode D2 coupled between the base terminal of the second PNP transistor Tr2 and ground. ). In a normal operation in which the first connector 112 and the second connector 114 are coupled to each other, the base terminal of the second PNP transistor Tr2 is the second diode D2 and the second terminal b2 of the second connector 114. ), The second terminal b1 of the first connector 112, the conductive wire, the first terminal a1 of the first connector 112, and the first terminal a2 of the second connector 114. Since the second PNP transistor Tr2 is turned on in connection with the side, the connector disconnection signal S Conn maintains the "H" level.

On the other hand, when the first connector 112 is separated from the second connector 114, the second PNP transistor Tr2 is turned off, so the connector disconnection signal S Conn transitions to the "L" level.

Here, the body ground or the vehicle ground has the same meaning, and the body ground and the ground in the separation signal generator 130 are commonly tied.

The repeater interface unit 140 interfaces with the repeater and receives a signal related to the state information of the repeater. For example, it is possible to receive at least one or more status signals of signals, such as whether a failure of the repeater occurs, the operating voltage.

The GPS module 150 measures current location information of the place where the mobile communication repeater is installed. The location information is initialized in the state where the security management module 110 is installed, and is matched with a unique identification number of the mobile communication repeater.

The MCU 120 may output a split signal output from the split signal generator 130, a signal related to the status information of the repeater received from the repeater interface unit 140, and current position information of the repeater measured by the GPS module 150. Receive The MCU 120 determines whether the repeater is stolen from the received signals, and immediately outputs to the transceiver 180 when theft occurs. In addition, the MCU 140 periodically outputs the state information of the repeater received from the repeater interface unit 140 to the transceiver 180.

The transceiver 180 transmits the failure signal detected by the security management module 110 and the state information of the repeater to the monitoring system located remotely through the antenna 190. As one example, a broadband mobile communication module may be used.

The MCU 120 may process a repeater control signal received remotely or a call signal for requesting information transmission in relation to the repeater state. For example, when a call signal is received, the server transmits the call status information and status information of the repeater received by the repeater interface unit 140 even before a reporting period to the server that sent the call signal. In addition, when receiving a relay lock signal from a remote location, the control to stop the operation of the repeater.

5 is a block diagram illustrating a repeater operation locking unit, and FIG. 6 is a circuit diagram illustrating a circuit configuration of the repeater operation locking unit. As shown, the security management module 110 is provided with a repeater operation lock unit 125 to lock the operation of the repeater in response to the remote lock signal.

Referring to FIG. 6, the repeater operation lock unit 125 may include a relay operation lock relay (in FIG. 6, a coil of the relay operation lock relay), an NPN transistor Tr4, and a reflux for protecting the NPN transistor Tr. A diode D5 and a bypass capacitor C2, a transient voltage suppress diode D6 for surge absorption, and a surge absorption capacitor C3.

As shown in FIG. 6, a repeater power terminal is connected to one side of a coil of the relay operation lock relay to receive power from the repeater, and an NPN transistor Tr4 is disposed on the other side of the coil. Specifically, the base terminal of the NPN transistor Tr4 receives the start lock signal KILL sig from the MCU 120, the collector terminal is connected to one side of the coil of the repeater operation locking unit 125, and the emitter terminal is grounded. do.

Normally, in the turn-off state of the NPN transistor Tr4, one side of the coil of the relay operation lock relay is floated so that the relay operation lock relay is in the OFF state.

When the MCU 120 receives the lock signal from the outside, the lock signal KILL sig is applied to the repeater operation lock unit 125. Accordingly, as the NPN transistor Tr4 is turned on, power applied to the coil side of the relay operation lock relay is connected to the ground side through an emitter, and the relay operation lock relay is turned on. Accordingly, the start lock state may be maintained until the NPN transistor Tr4 is turned off.

Here, the reflux diode D5 consumes back EMF generated when the relay operation lock relay is turned off, and the remaining portion of the consumed current flows to the ground side by the bypass capacitor C2. Accordingly, the NPN transistor Tr4 can be protected from the counter electromotive force generated during the relay-off operation by the reflux diode D5.

The transient voltage suppress diode D6 absorbs the voltage when the voltage across the collector terminal of the NPN transistor Tr4 and the relay is excessively increased to, for example, 33V or more, thereby protecting the devices. The surge absorption capacitor C3 connected in parallel to the transient voltage suppress diode D6 also serves to protect the devices by grounding the excessive surge voltage.
