Abstract

A method for controlling operation of an internet of things device includes: controlling, by a processor, a first device to be in an on state and controlling the processor to be in a sleep mode when the processor determines that a user is located outside a place object; receiving, by the processor, a control signal from the first device and waking up to an operation mode; controlling, by the processor, a second device to be in an on state, wherein the second device is installed in an entrance side of the place object and detects a user'"'"'s entry into the place object; controlling, by the processor, the processor to be connected to an external control device, controlling the first device and the second device to be in an off state, and controlling a third device to be in an on state when the user'"'"'s entry into the place object is detected; and detecting, by the processor, whether the user is located inside the place object using an output of the third device.

Claims

1. A method for controlling operation of an internet of things (IoT) device, comprising:

controlling, by a processor, a sub-device to be in an on state and controlling the processor to be in a sleep mode when the processor determines that a user is located outside a place object;

receiving, by the processor, a control signal from the sub-device and waking up the processor to be in an operation mode in response to the control signal received from the sub-device;

controlling, by the processor, an entrance detection device to be in an on state, wherein the entrance detection device is located in an entrance side of the place object and detects a user'"'"'s entry into the place object;

when the user'"'"'s entry into the place object is detected by the entrance detection device, controlling, by the processor, the processor to be connected to an external control device, controlling the sub-device and the entrance detection device to be in an off state, and controlling an active state sensing device to be in an on state, wherein the active state sensing device is located inside the place object and detects the user located inside the place object; and

determining, by the processor, whether the user is located inside the place object using an output of the active state sensing device,

wherein the processor turns on the sub-device, turns off the entrance detection device and the active state sensing device, and goes into the sleep mode when the processor determines that the user is located outside the place object.

2. The method of claim 1, further comprising:

controlling, by the processor, the entrance detection device detecting whether the user exits outside of the place object to be in an on state when the processor determines that the user is not located inside the place object using the output of the active state sensing device.

3. The method of claim 2, wherein the processor determines that the user is located outside the place object when the processor determines that the user is not located inside the place object using the output of the active state sensing device and the processor determines that the user exits outside of the place object using the entrance detection device.

4. The method of claim 1, wherein the processor controls the entrance detection device to be in the on state when the processor detects that the user located outside the place object moves to the place object.

5. A system for controlling operation of an internet of things (IoT) device, comprising:

a processor coupled to a memory storing functions of the processor;

a sub-device configured to receive a control signal transmitted from an external control device and transmit the received control signal;

an entrance detection device that is located in an entrance side of a place object and is configured to detect a user'"'"'s entry into the place object; and

an active state sensing device that is located inside the place object and is configured to inform that the user is inside the place object by transmitting an operation signal,

wherein the processor is configured to;

operate in a sleep mode when the user is outside the place object,

wake up in response to the control signal received from the sub-device,

turn off the sub-device and the entrance detection device and turn on the active state sensing device when the user'"'"'s entry into the place object is detected by the entrance detection device, and

turn on the sub-device, turn off the entrance detection device and the active state sensing device, and go into the sleep mode when the processor determines that the user is located outside the place object.

6. The system of claim 5, wherein the processor turns on the entrance detection device when the user located outside the place object moves to the place object.

7. The system of claim 5, wherein the processor is connected to the external control device and turns off the sub-device when the user'"'"'s entry into the place object is detected by the entrance detection device.
