Abstract

A smart deadlock system according to an embodiment of the present invention includes a thumb-turn, a key cylinder, a connecting shaft connecting the thumb-turn and the key cylinder, and a sensor module. The sensor module may include a sensing unit to sense a rotation state of a rotation sensing element inserted onto the connecting shaft, and generate sensing information associated with the rotation state of the rotation sensing element, and a rotation information generation unit to receive the sensing information from the sensing unit, and generate rotation information associated with an extent of rotation of the rotation sensing element based on the sensing information. According to the smart deadlock system, it is possible to check the operation of the deadlock more accurately by sensing the rotation state of the rotation sensing element using the sensor.

Claims (30)

1. A smart deadlock system, comprising:

a thumb-turn;

a key cylinder;

a connecting shaft connecting the thumb-turn and the key cylinder; and

a sensor module comprising:

a sensing unit to sense a rotation state of a rotation sensing element inserted onto the connecting shaft, and generate sensing information associated with the rotation state of the rotation sensing element; and

a rotation information generation unit to receive the sensing information from the sensing unit, and generate rotation information associated with an extent of rotation of the rotation sensing element based on the sensing information.

2. The smart deadlock system according to claim 1 , wherein the sensing unit comprises:

a generation unit disposed on one side of the rotation sensing element to generate a predetermined light source toward the rotation sensing element; and

a receiving unit disposed on an other side of the rotation sensing element to receive the light source passing through the rotation sensing element.

3. The smart deadlock system according to claim 1 , wherein the rotation sensing element is a driving gear having a plurality of teeth extending along an outer periphery, the teeth spaced apart at a predetermined interval.

4. The smart deadlock system according to claim 1 , wherein the rotation sensing element is a rotation sensing plate having a plurality of light source passage holes along an outer peripheral direction, the light source passage holes spaced apart at a predetermined interval.

5. A smart deadlock system, comprising:

a thumb-turn;

a key cylinder;

a connecting shaft connecting the thumb-turn and the key cylinder; and

a sensor module to sense a motion of the connecting shaft, the smart deadlock system comprising:

a comparison module including a comparison unit to receive motion information of the connecting shaft from the sensor module in a sequential order and compare previous motion information with current motion information, and a change information generation unit to generate change information of the motion information; and

a control module to receive the change information generated by the comparison module and control a storage location of the change information.

6. The smart deadlock system according to claim 5 , further comprising:

a memory module to store the change information received from the control module;

a communication module to transmit the change information received from the control module; and

a mobile terminal including a storage unit to store the change information and a transmission unit to transmit a driving command, the mobile terminal performing near-field communication with the communication module.

7. The smart deadlock system according to claim 6 , wherein the control module is configured to perform control to store the change information in the memory module, and when the mobile terminal is connected to the communication module, the change information is transmitted to the mobile terminal through the communication module, not via the memory module, and stored in the storage unit.

8. The smart deadlock system according to claim 6 , further comprising:

a wireless communication bridge to receive the change information from the communication module and transmit the change information to a server;

the server to store the change information received from the wireless communication bridge and transmit the change information to the mobile terminal; and

the mobile terminal including a display unit to receive the change information from the server and display the change information, and the transmission unit to transmit the driving command.

9. The smart deadlock system according to claim 5 , wherein the comparison unit determines if the previous motion information is the same as the current motion information; and

when the previous motion information is not the same as the current motion information, the change information generation unit generates the current motion information as the change information.
