Abstract

A remote control system including a remote control device and a first controllable device is provided. The remote control device has a wireless communication module, and is configured to execute a pairing connection operation. The first controllable device has a wireless communication function, and is configured to transmit first identification information. When executing the pairing connection operation, the remote control device obtains the first identification information of the first controllable device through the wireless communication module. The remote control device continuously updates and records the first identification information within a preset time range. The remote control device determines whether signal strength of the first controllable device has undergone a preset change within the preset time range based on the first identification information, and if so, the remote control device decides to connect to the first controllable device through the wireless communication module. In addition, a remote control method is provided.

Dependent claims

A remote control system comprising:

a remote control device having a wireless communication module, the remote control device being configured to execute a pairing connection operation;
and
a first controllable device having a wireless communication function, and being configured to transmit first identification information to the remote control device, wherein the first identification information includes a unique identifier of the first controllable device and a received signal strength indication (RSSI) of the first controllable device,
wherein when the remote control device executes the pairing connection operation, the remote control device identifies the first controllable device by receiving the unique identifier of the first controllable device, and the remote control device continuously updates and records the RSSI of the first controllable device within a preset time range so as to determines whether the first controllable device has been displaced based on the RSSI of the first controllable device,
wherein when the RSSI of the first controllable device indicates that wireless signals received by the first controllable device has a signal strength change within the preset time range, the remote control device determines that the first controllable device has been displaced, and the remote control device connects to the first controllable device through the wireless communication module.

A remote control method adapted to a remote control system, the remote control system comprising a remote control device and a first controllable device, wherein the remote control method comprises:

when the remote control device executes a pairing connection operation, obtaining first identification information of the first controllable device by the remote control device through a wireless communication module, wherein the first identification information includes a unique identifier of the first controllable device and a received signal strength indication (RSSI) of the first controllable device;
identifying the first controllable device by receiving the unique identifier of the first controllable device;
continuously updating and recording the RSSI of the first controllable device so as to determine whether the first controllable device has been displaced based on the RSSI of the first controllable device within the preset time range;
when the RSSI of the first controllable device indicates that wireless signals received by the first controllable device has a signal strength change within the preset time range, the remote control device determines that the first controllable device has been displaced;
and
when determining that the first controllable device has been displaced, connecting to the first controllable device by the remote control device through the wireless communication module.
