When the voltage is applied to the 12V contact 122 and the Com contact 123 by the locked state detecting unit 160, the LED control unit 120 is installed on the LED 12 of the door 10. 212 is operated, and the door 10 is locked. The contact 124 (that is, the status signal of FIG. 3) indicating the locked state of the E / M lock device 212 is also changed to the closed state.

The main word detecting unit 120 is an E / M lock device installed in the main word 12 of the door 10 because the voltage is cut off from the 12 V contact 122 and the Com contact 123 by the locked state detecting unit 160. 212 stops and the door 10 enters the open state. The contact 124 (that is, the status signal of FIG. 3) indicating the locked state of the E / M lock device 212 is also changed to the open state.

The sub-door detecting unit 140 is installed in the sub-door 14 of the door 10 to detect the open and closed state of the sub-door 14 (see FIG. 4). To this end, as shown in FIG. 5, the subdoor detection unit 140 includes a manual locking module 142 and a subdoor detection module 144.

When the subdoor 14 of the door 10 is locked by the manual locking module 142, the bolt 143 of the manual locking module 142 moves toward the upper side of the door housing 16. As it rises and contacts the relay contact 146 of the sub-door sensing module 144, the state changes to the closed state.

When the subdoor 14 of the door 10 is opened through the operation of the manual locking module 142, the sub-door detecting unit 140 moves the bolt 143 of the manual locking module 142 to the lower side of the door housing 16. As it is lowered and spaced apart from the relay contact 146 of the sub-door detection module 144, the state changes to the open state.

To this end, the sub-door detection unit 140 is installed by processing the door housing 16 in the same way as the existing dead bolt lock, and by using the manual locking module 142 to open and close the door 10 to the sub-door 14 ) Is obtained so as to obtain a lock state signal of the door, and to know the locked state of both doors of the door 10 by connecting a contact in series with the E / M lock (or dead bolt lock) installed in the main control 12.

That is, as shown in FIG. 6, the cover 16 is formed to cover the flaw of the cover edge generated after cutting the upper part of the door housing 16 to install the subdoor detecting unit 140. At this time, the cover 16 is formed with a hole 18 into which the bolt 143 is inserted.

As shown in FIG. 7, two holes are formed at the lower end of the subdoor detection unit 140 so as to change the direction of the relay constituting the subdoor detection module 144 according to the position (left and right) of the subdoor 14. 145 (ie, a hole into which the bolt 143 of the manual locking module 142 is inserted).

As shown in FIG. 8, the side of the sub-door detecting unit 140 may be configured to change the position of the sub-door detecting module 144 (that is, the relay) according to the length of the bolt 143 of the manual locking module 142. The bolt hole 147 for fixing the door detection module 144 is formed in three stages.

As shown in Figure 9, the sub-door detection module 144 of the sub-door detection unit 140 is a micro switch 125VAC 15A, 14VDC 15A or more relays are used. Of course, other relays may be used depending on the state of the door 10.

The locked state detecting unit 160 determines and outputs the locked state of the door 10 based on the detection signals from the main control unit 120 and the sub-door detecting unit 140. At this time, when the locked state detecting unit 160 detects that both the primary word detecting unit 120 and the sub-door detecting unit 140 are locked, the locked state detection unit 160 determines that the door 10 is locked and the primary word detecting unit 120 is detected. And at least one of the sub-door detection unit 140 is determined to be in an open state of the door 10. In this case, the locked state of the door 10 of the locked state detecting unit 160 according to the detection signals from the main control unit 120 and the sub-door detecting unit 140 is as shown in Table 1 below.

The locked state detecting unit 160 transmits the determined locked state of the door 10 to the access management server 500 through the network 400. The locked state detecting unit 160 is a state in which all of the relay contact 146 of the E / M lock device 212 of the main control unit 120 and the subdoor detecting module 144 of the subdoor detecting unit 140 are closed. When the closed circuit is configured, the locked state signal is transmitted to the access management server 500 through the network 400.

The locked state detecting unit 160 may include at least one of the E / M lock device 212 of the main control unit 120 and the relay contact 146 of the subdoor detecting module 144 of the subdoor detecting unit 140. The change circuit is opened to the open state and the open state signal is transmitted to the access management server 500 through the network 400.

To this end, as shown in FIG. 5, the locked state detecting unit 160 includes a first sensing module 161, a second sensing module 162, a determination module 163, a control module 164, and a communication module ( 165, and a display module 166.

The first detection module 161 receives a detection signal from the master word detecting unit 120.

The second detection module 162 receives a detection signal from the subdoor detection unit 140.

The determination module 163 determines the locked state of the door 10 based on the detection signals from the first sensing module 161 and the second sensing module 162. In this case, when both closed state signals are input from the first sensing module 161 and the second sensing module 162, the determination module 163 determines that the door 10 is locked and the first sensing module 161. And when an open state signal is input from at least one of the second detection modules 162, determine that the door 10 is open.

Here, the determination module 163 determines that the closed circuit configuration is broken if any one of the following three operations is performed.

1.When the door 10 is opened by entry and exit, the contact is opened by the operation of the E / M lock device 212.

2. When exiting from the inside of the building, press the EXIT button 125, the power of the E / M lock device 212 is lost and the door is unlocked and the contact is opened.

3. When the door is opened by releasing the manual locking module 142 of the subdoor 14, the contact of the subdoor detection unit 140 is opened.

The control module 164 transmits and outputs the determination result of the determination module 163 to the access management server 500.

The communication module 165 transmits the locked state of the door 10 to the access management server 500 under the control of the control module 164.

The display module 166 displays the locked state of the door 10 under the control of the control module 164. Here, the display module 166 may be omitted when the door management server 500 outputs the locked state of the door 10.

Hereinafter, the door lock state detection method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 11 is a flowchart illustrating a door locking state detection method according to an embodiment of the present invention.

First, the master word detecting unit 120 is installed in the main word 12 of the door 10 detects the open and closed state of the main word 12 and transmits to the locked state detecting unit 160. In this case, when the voltage is applied to the 12V contact 122 and the Com contact 123 by the locked state detecting unit 160, the main control unit 120 is installed in the main control unit 12 of the door 10. The lock device 212 is operated so that the door 10 is locked. The contact 124 (that is, the status signal of FIG. 3) indicating the locked state of the E / M lock device 212 is also changed to the closed state. The main word detecting unit 120 is an E / M lock device installed in the main word 12 of the door 10 because the voltage is cut off from the 12 V contact 122 and the Com contact 123 by the locked state detecting unit 160. 212 stops and the door 10 enters the open state. The contact 124 (that is, the status signal of FIG. 3) indicating the locked state of the E / M lock device 212 is also changed to the open state.

In addition, the sub-door detecting unit 140 is installed in the sub-door 14 of the door 10 detects the open and closed state of the sub-door 14 and transmits to the locked state detecting unit 160. At this time, when the sub-door 14 of the door 10 is locked through the operation of the manual locking module 142, the sub-door detecting unit 140 has the bolt 143 of the manual locking module 142 of the door housing 16. Ascending to the upper side to operate the relay contact 146 of the sub-door detection module 144 is changed to the closed state.

The first sensing module 161 and the second sensing module 162 detect the locked state of the main control 12 and the sub-door 14 (S100). That is, the first detection module 161 receives a detection signal corresponding to the locked state of the control word 12 from the control word 120, and the second detection module 162 receives the sub-door detection unit 140. Receives a detection signal corresponding to the locked state of the sub-door (14).

The determination module 163 determines the locked state of the door according to the detection signals of the first detection unit and the second detection unit (S120). At this time, the determination module 163 when the first detection module 161 and the second detection module 162 receives the signal of the locked state both determine the locked state of the door 10, the first detection module 161 And when the detection signal of the open state is received by at least one of the second detection modules 162, the door 10 is determined to be in the open state.

If the determination module 163 determines that the door is open (S140; YES), the control module 164 generates an alarm (S160).

The control module 164 transmits the door locked state to the access management server 500 (S180). In this case, the control module 164 may control to output the locked state of the door 10 through the display unit.

As described above, according to the present invention, the door lock state detection device and method is replaced with an expensive locked state monitoring device (i.e., E / M lock or D / B lock) in the sub-door 14 with less entry and exit. By monitoring the locked state of the manual locking device of the door 14, there is an effect that can minimize the cost of the facility for monitoring the locked state of the door (10).

This saves approximately 77% of the facility cost compared to a locked state monitoring device (ie E / M Lock or D / B Lock).

Although a preferred embodiment according to the present invention has been described above, modifications can be made in various forms, and those skilled in the art will appreciate various modifications and modifications without departing from the claims of the present invention. It is understood that it can be carried out.
