In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and similar reference numerals are assigned to similar parts throughout the specification.

Throughout the specification, when a part "includes" a certain component, it means that other components may be further included rather than excluding other components unless otherwise stated.

Now, a control method and an apparatus thereof using the state of a communication port according to an embodiment of the present invention will be described with reference to the drawings.

1 shows a LAN (Local Area Network) cable for explaining a loop phenomenon of a communication port according to an embodiment of the present invention.

Referring to FIG. 1, a cable 100 used in a LAN method, which is a short-range communication using a standard Ethernet protocol, is configured in 4 pairs (8 strands). In general, in order to transmit data at a speed of 100 Mbps, 4 strands (No. 1, No. 2, No. 3, No. 6) are used out of the 8 strands of the cable 100, and 8 strands (No. 1, No. 2, 3, 4, 5, 6, 7, 8) are all used. Here, 1 and 2 are used for transmission, and 3 and 6 are used for reception.

At this time, in ports to which cables 1 and 3, and 2 and 6 are connected, a loop occurs in which packets start at the port and end again at the port.

An embodiment of the present invention monitors the environment of a control target area by using the loop phenomenon of the communication port. Here, the control includes door opening/closing monitoring, flood monitoring, fire monitoring, and the like.

In addition, as shown in Fig. 1, the LAN cables 1 and 3, and 2 and 6 connected to each other will be referred to as control cables.

2 shows the overall configuration of a control system according to an embodiment of the present invention.

Referring to FIG. 2, each communication device 200 installed in a plurality of control target areas 1 is connected to a control point through a control cable 100 described in FIG. 1. At this time, the communication equipment 200 used the L2 switch. However, the L2 switch is an example of a communication device to which an embodiment of the present invention is applied. Hereinafter, in this specification, it is described as an L2 switch for convenience of description, but the communication device 200 is not limited to the L2 switch, It is a concept including all communication equipment capable of implementing the embodiments of the present invention.

The L2 switch 200 is a switch operating in layer 2 and switches based on the MAC (Media Access Control) address of a packet, that is, to which port to send. Ports of the L2 switch 200 have respective MAC addresses.

At least one port of the L2 switch 200 is connected to an independent control point and an individual control cable 100. The control server 400 monitors the environment based on the state change of each port provided by the L2 switch 200.

When the state of the port is changed, the L2 switch 200 transmits a syslog message including information on the port whose default state is changed to the control server 400 connected through the communication network 300. At this time, when the state of the port is changed, the L2 switch 200 saves the port status as its own log file and generates a syslog message, so that the control server 400 uses a User Datagram Protocol (UDP) unicast. ).

The control server 400 may perform control, that is, environment monitoring by selectively utilizing a change in a loop on/off state of the ports of the L2 switch 200 or activation/deactivation of a port.

According to one embodiment, the default state of each port is set to a loop-on (On) or loop-off (Off) state. The L2 switch 200 generates a syslog message when the default state is changed, that is, when it is changed from loop on to loop off or from loop off to loop on. When the L2 switch 200 sets the default state to loop-on, the corresponding port is blocked in the default state. Here, the block is set to logically disable communication. When the L2 switch 200 detects the loop-off of the port, the L2 switch 200 unblocks the corresponding port. In addition, the L2 switch 200 generates a syslog message according to block processing or a syslog message according to unblock processing, and transmits it to the control server 400. The control server 400 recognizes a change in a monitoring target or a monitoring area matched to a corresponding port based on such a syslog message.

According to another embodiment, when the L2 switch 200 does not have a loop detection function, the default state of each port may be set to port up or port down. In a state in which the control cable 100 connected to the port is tangential, current or electricity is detected at the corresponding port, so the L2 switch 200 recognizes the port as an up state. However, when the connection of the control cable 100 connected to the port is released, it is the same as that the connection between the port and the control cable 100 is eventually released, so that no current or electricity is detected at the port. Accordingly, the L2 switch 200 recognizes the port as a down state. When the default state of the L2 switch 200 is changed, that is, when the port is changed from port up to port down or from port down to port up, a syslog message in which a log indicating port up or port down is recorded is displayed. It is generated and transmitted to the control server 400. Then, the control server 400 recognizes a change in a monitoring target or a monitoring area matching a corresponding port based on a syslog message.

The plurality of control target areas 1 include a communication office, an apartment building, a building, a solar energy storage system (ESS), a communication box (Broad Band Box, BBX), and the like.

When a syslog message is received, the control server 400 transmits an alarm message to the designated control terminal 500. Here, the syslog message may include attributes as shown in Table 1 below.

property Explanation HostIP IP address of the system sending the log HostName The name of the system sending the log SeverityLevel Log importance SyslogMessage Log content ProcessID ID of the process that generated the log EventTime Date and time the event was generated

The control server 400 identifies the control target area (1) based on the'HostIP' of the syslog message, and also within the control target area (1) based on the port number or MAC address included in the'SyslogMessage'. Control points can be identified.

The control server 400 may transmit an alert message or an alert release message to the control terminal 500 based on the contact information matched to the control target area 1 and the control point. Here, a message service of a mobile communication service provider such as SMS (Short Message Service) may be used as the alert message or the alert release message.

In addition, according to an embodiment of the present invention, the control server 400 is connected to a plurality of L2 switches 200 to receive a syslog message (syslog) equipment (not shown) and a syslog ( syslog) It can be separated into a control server (not shown) that performs control by interpreting a syslog message output from an equipment (not shown). At this time, the control server (not shown) may transmit an alarm message or an alarm release message to the control terminal 500, or may display an alarm occurrence point on the control screen so that the operator can check it.

Hereinafter, the embodiment of the present invention will be described as an example in which the L2 switch 200 has a loop detection function, but the same can be applied to the above-described port up or port down embodiment.

This is an example showing the closed state, Figure 7b is an example showing an open state of the door opening and closing system according to an embodiment of the present invention, Figure 8 is an example of applying a control cable according to an embodiment of the present invention to flood monitoring, Figure 9 is an example of applying a control cable according to an embodiment of the present invention to fire monitoring.

Referring to FIG. 3, the L2 switch 200 includes at least one control port 201, at least one communication port 203, a memory 205, and a processor 207.

At this time, at least one control port 201 is a port designated to be connected to a control cable (100 in FIG. 1) among a plurality of communication ports provided in the L2 switch 200, and at least one communication port 203 is L2 These are the remaining communication ports excluding at least one control port 201 from among the plurality of communication ports provided in the switch 200.

Here, the control port 201 may be a wired port, but the communication port 203 may be a wired port or a wireless port.

The memory 205 is connected to at least one control port 201, at least one communication port 203, and the processor 207, and a syslog message according to whether or not the port state of the control port 201 is changed. It includes a program consisting of instructions that define a series of operations to generate and transmit to the control server 400. The program is combined with hardware such as memory 205 and processor 207 to implement the present invention.

The processor 207 executes a program stored in the memory 205. The processor 207 blocks at least one control port 201 in a default state. Here, the block is set to logically disable communication.

The default state of the control port 201 is loop on or loop off, and the default state of each control port 201 may be different.

The processor 207 is a block-processed at least one control port 201, if the default state is changed, for example, in the loop-off state from the loop-on state, the loop detect link down (Loop detect link down). Generates a syslog message indicating that it is unblocked. In addition, when the processor 207 returns from the loop-off state to the loop-on state, the processor 207 generates a syslog message indicating that the block is processed by a loop detect link up.

In addition, the processor 207 may perform logical separation of a network by allocating a virtual LAN (VLAN) identifier based on a MAC or port number. In this case, different VLAN identifiers may be allocated to at least one control port 201 and at least one communication port 203, and different VLAN identifiers may be allocated for each control port 201. The reason why the VLAN identifiers are differently allocated is to prevent a communication failure failure of the L2 switch 200 itself due to a loop state of the control port 201.

4, there are a plurality of ports (P1) outside the L2 switch 200, of which 1, 2, 3, 4 are designated as control ports 201, 5, 6, 7, 8 are It may be designated as a communication port 203. The control port 201 is connected to each control point through a control cable 100.

According to one embodiment, the second control port is connected to the access door monitoring point through the first control cable 101. Referring to FIG. 5, the other end of the first control cable 101 having one end connected to the control port No. 2 is connected to the door opening/closing monitoring device 3. At this time, the 2nd and 6th strands, and the 1st and 3rd strands drawn out from the other end of the first control cable 101 are connected to the access door opening/closing monitoring device 3, respectively. 6, the 1st and 3rd strands are connected to the fixed connector 4 in a tangential state, and the 2nd and 6th strands are connected to the door opening/closing monitoring device 3 in a tangential state. May be.

At this time, the door opening/closing monitoring device 3 is engaged with each other while being mounted on the door 2-1 and the upper part 2-3 of the door 2-1. And when the door (2-1) is closed, the door (2-1) and the upper part (2-3) are in close proximity to each other, and when the door (2-1) is opened, the door (2-1) is It is separated from 2-3) in the direction that the door (2-1) opens.

7A and 7B, the door opening/closing monitoring device 3 is a magnetic switch and includes a reed switch 31 and a fixed magnet 32. The reed switch 31 includes two contact portions 33 and 34 and two connection portions 35 and 36. The first connection part 35 connected to the 2nd strand (or 1st strand) drawn out from the control cable 101 is connected to the first contact part 33, and the 6th strand drawn out from the control cable 101 The second connection part 36 connected to the (or No. 3 strand) is connected to the second contact part 34. The fixed magnet 32 may be a permanent magnet.

As shown in FIG. 7A, when the fixed magnet 32 comes into contact with the reed switch 31, the two contact portions 33 and 34 contact each other, and the second strand and the sixth strand are tangential. As shown in FIG. 7B, when the contact between the fixed magnet 32 and the reed switch 31 is released, that is, when the fixed magnet 32 is separated from the reed switch 31, the two contact portions 33 and 34 are also separated from each other. And the tangent between the 2nd and 6th strands is released.

In the locked state of the door in which the fixed magnet 32 is in contact with the reed switch 31, the 2nd strand and the 6th strand are tangential, so the 2nd port is in a loop-on state. In addition, when the fixed magnet 32 enters the door open state in which contact with the reed switch 31 is released, the tangent between the second strand and the sixth strand is released, and the second port is in a loop-off state. Therefore, when the second port is changed from the loop-on state to the loop-off state, the L2 switch 200 transmits a syslog message informing this to the control server 400. Since the control server 400 is designated as port 2 as an access door monitoring port, when the state of port 2 is changed, it can recognize that the door is open. Here, the control event is the door opening.

Again, referring to FIG. 4, according to another embodiment, the third control port is connected to the flood monitoring point through the second control cable 103. 8, the first strand and the third strand drawn out from the second control cable 103 are connected to the fixed connector 4 in a tangential state. In addition, the second and sixth strands drawn out from the second control cable 103 are tangentially bound by a water-soluble thread 5 and are positioned at the submersion monitoring point. When immersion occurs at the immersion monitoring point, the water-soluble thread dissolves in the water, releasing the tangent between the 2nd and 6th strands. Then, since port 3 is in a loop-off state from a loop-on state, the L2 switch 200 transmits a syslog message informing this to the control server 400. Since port 3 is designated as a flood monitoring port, the control server 400 can recognize that flooding has occurred when the state of port 3 is changed. Here, the control event is flooding.

Again, referring to FIG. 4, the control port 4 is connected to the fire monitoring point through a third control cable 105. Referring to FIG. 9, the second and sixth strands drawn from the third control cable 105 are connected to the fixed connector 4 in a tangential state. And the first strand and the third strand are connected to the electrical relay unit (6). Of course, by configuring two electric relay units 6, the second strand and the sixth strand may also be connected to the electric relay unit 6.

The electrical relay unit 6 includes a relay 61 connected to the flame sensor 7, a switch SW, and a power supply unit 62 connected to the relay 61. The flame sensor 7 may be a heat sensor, a flame sensor, or the like.

Both ends of the switch SW are connected to the first strand and the third strand, and the default state of the switch SW may be switched on or switched off.

According to one embodiment, the default state of the switch SW is off. That is, the relay 61 is designed to cut off the power output from the power supply unit 62. When the switch (SW) is off, the first strand and the third strand are not in a tangent state.

At this time, when the flame sensor 7 detects a fire, a fire detection signal is generated and output to the relay 61. The relay 61 may be designed to supply power to the switch SW when a fire detection signal is input from the flame sensor 7. Accordingly, the relay 61 turns on the switch SW by supplying power to the switch SW. Then, strand 1 and strand 3 are tangent.

That is, the second strand and the sixth strand of the third control cable 105 are fixed in a tangent state, and the first strand and the third strand are selectively connected depending on whether the flame sensor 7 detects fire. Since the default state of the switch SW is off, the default state of port 4 is the loop off state. When the loop is turned on from the loop off state due to fire detection, the L2 switch 200 transmits a syslog message informing this to the control server 400. Since port 4 is designated as a fire monitoring port, the control server 400 may recognize that a fire has occurred when the state of port 4 is changed. Here, the control event is fire detection.

10 is a block diagram illustrating a hardware configuration of a control server according to an embodiment of the present invention, and FIG. 11 is an example of an alarm message or an alarm release message according to an embodiment of the present invention.

First, referring to FIG. 10, the control server 400 includes a communication unit 401, a memory 403, a control database 405, and a processor 407.

The communication unit 401 is connected to the processor 407 to transmit and receive data. The communication unit 401 receives a syslog message from the L2 switch 200 through the communication network 300. The communication unit 401 transmits an alarm message or an alarm release message generated by the processor 407 to the control terminal 500 through the communication network 300. At this time, the communication unit 401 may transmit a message alarm message or an alarm release message to the control terminal 500 through a message service center (not shown) such as a short message service center (SMSC).

The memory 403 is connected to the processor 407 and stores a program including instructions for executing the operation of the control server 400. The program is combined with hardware such as the memory 403 and the processor 407 to implement the present invention.

The control database 405 stores information necessary for identifying a control target area and a control point based on a syslog message received by the processor 407 from the L2 switch 200. For example, the control database 405 may include a table as shown in Table 2 below.

L2 HostIP Control position Port number Control type Contact 10.10.10.10 Buksan Guksa Temple
2nd floor communication room Number 4 Fire alarm 010-1234-5678 … … … … …

The processor 407 checks HostIP from a syslog message received from the L2 switch 200. And based on the checked HostIP, check the control location in Table 2. The processor 407 checks the port number from the SyslogMessage of the syslog message received from the L2 switch 200. And based on the checked port number, check the control type and contact information in Table 2. If the port number is 4, since it is fire monitoring, the processor 407 generates an alarm message P3 or an alarm release message P5 as shown in FIG. 11. Then, it is sent to the contact identified in Table 2.

Here, it is possible to use a MAC address other than a port number.

Now, the operation of the control system described above will be described. In this case, the same reference numerals are used for descriptions of the same components as those described in FIGS. 1 to 11.

12 is a series of flow charts showing a control method according to an embodiment of the present invention.

Referring to FIG. 12, each control port 201 of the L2 switch 200 is connected to each control cable 100 connected to different control points (S101).

The L2 switch 200 sets the default state of the at least one control port 201 to loop on or loop off (S103). In this case, a default state may be set differently for each control port 201. The default state depends on the tangent state of the connected control cable 100. When the tangential state of the control cable 100 is a loop-on state, the default state is a loop-on state, and when the tangential state is a loop-off state, the default state is a loop-off state.

The L2 switch 200 is set to generate a syslog message when the state of the control port 201 is changed (S105).

The L2 switch 200 monitors the presence or absence of a state change for each control port 201 (S107), and determines whether there is a control port 201 whose state is changed (S109).

When the state of the control port 201 is changed, the L2 switch 200 generates a syslog message (S111). At this time, the syslog message includes a log indicating that the port status has changed from loop-on (or loop-off) to loop-off (loop-on), the IP address of the L2 switch, and the port number whose status has changed.

The L2 switch 200 transmits the generated (S111) syslog message to the control server 400 through the control port 201 and a separate communication port 203 (S113).

Meanwhile, the control server 400 creates a control database 405 based on the host IP of the L2 switch and the port number of the L2 switch in advance (S115), which may be as shown in Table 2.

The control server 400 uses the host IP extracted from the received syslog message (S113) to identify the location of the control target area where the syslog message has occurred from the control database 405 (S117). Then, the control type in which the syslog message has occurred is identified from the control database 405 using the port number extracted from the syslog message (S119). Here, the control type represents the control point within the control target area.

The control server 400 generates an alert message according to the identified control target area and control type (S117 and S119) and transmits an alert message to a phone number matching the extracted host IP and port number (S121).

13 is a series of flowcharts illustrating a control method according to another embodiment of the present invention, and may be a step added after step S121 of FIG. 12.

Referring to FIG. 13, the L2 switch 200 monitors whether the control port 201 returns to the default state (S201), and determines whether to return to the default state (S203). That is, the control port 201 whose default state has been changed is targeted.

If there is a control port 201 returning to the default state, the L2 switch 200 generates a syslog message indicating the return of the control port 201 (S205). This syslog message contains the IP address of the L2 switch, the port number returned to its default state, and a log indicating that the port state has returned from loop off (or loop on) to loop on (loop off).

The L2 switch 200 transmits a syslog message to the control server 400 (S207).

With reference to the control database 405, the control server 400 identifies the control target area with the host IP extracted from the syslog message received in step S207 (S209), and the syslog received in step S207. ) The control type is identified by the port number extracted from the message (S211). The control server 400 generates an alarm release message according to the identified control target area and control type, and transmits the alarm release message to a phone number matching the extracted host IP and port number (S213).

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention defined in the following claims are also provided. It belongs to the scope of rights.
