Abstract

Provided are wireless charging equipment, a terminal, a wireless charging system comprising the same, a control method thereof, and a non-transitory computer readable storage medium having computer program recorded thereon. That is, the present invention can easily implement the present invention without a separate BLE beacon device by using the wireless charging infrastructure and improve operation efficiency of the entire wireless charging system by transmitting additional information (alternatively, specific information) to the peripheral BLE terminal for a time where the charging signal is not transmitted in the corresponding BLE by using the BLE of the resonance scheme wireless charging equipment.

Claims

1. Wireless charging equipment comprising:

a communication unit configured to communicate based on a Bluetooth low energy (BLE) scheme; and

a control unit configured to control the communication unit to verify the number of terminals connected to the wireless charging equipment including the communication unit, verify a standby time period when the charging signal is not transmitted to the terminal connected to the wireless charging equipment in a time slot based on the verified number of terminals, and transmit a beacon signal including additional information based on the verified standby time period by a broadcasting method.

2. The wireless charging equipment of claim 1, wherein the control unit predicts the standby time period when the charging signal is not transmitted to the terminal connected to the wireless charging equipment based on the verified number of terminals.

3. The wireless charging equipment of claim 1, wherein the additional information includes coupon information and product information in a store where the wireless charging equipment is installed.

4. The wireless charging equipment of claim 1, wherein the control unit controls the communication unit to verify a time period when the beacon signal including the additional information is transmittable in the standby time period and transmit the beacon signal to the terminal at the verified time period when the beacon signal is transmittable.

5. The wireless charging equipment of claim 1, wherein the control unit controls the communication unit to transmit the beacon signal to the terminal connected to the wireless charging equipment.

6. A control method of wireless charging equipment comprising:

communicating with one or more terminals based on a BLE scheme by means of a communication unit;

verifying the number of terminals connected to the wireless charging equipment including the communication unit by means of a control unit;

verifying a standby time period when a charging signal is not transmitted to the terminal connected to the wireless charging equipment in a time slot based on the verified number of terminals by means of the control unit; and

controlling the communication unit to transmit a beacon signal including additional information based on the verified standby time period by a broadcasting method by means of the control unit.

7. The control method of claim 6, wherein the controlling of the communication unit to transmit the beacon signal includes:

verifying a time period when the beacon signal is transmittable in the verified standby time period by means of the control unit; and

controlling the communication unit to transmit the beacon signal to the terminal connected to the wireless charging equipment at the verified time period when the beacon signal is transmittable, respectively.

8. A wireless charging system comprising:

a terminal configured to be wirelessly charged by an alliance for wireless power (A4WP) scheme; and

wireless charging equipment configured to verify a standby time period when the charging signal is not transmitted to the terminal in a time slot based on the verified number of terminals and transmit a beacon signal including additional information based on the verified standby time period by a broadcasting method.
