The moving platform 12 may be a device used to carry the wireless charging apparatus 14 and move the wireless charging apparatus 14 on a two-dimensional (2D) plane or in a three-dimensional (3D) space according to a control signal of the processor 10. Namely, the moving platform 12 and the wireless charging apparatus 14 are connected with each other.
The wireless charging apparatus 14 may transmit energy to an electronic apparatus by means of near field induction in a wireless manner. The electronic apparatus, after receiving the energy sent by the wireless charging apparatus 14, may use the received energy to charge a battery or directly in an operation of the electronic apparatus. The energy is transmitted between the wireless charging apparatus and the electronic apparatus by means of inductive coupling, and thus, no wired connection is required therebetween.
The sensor 16 is used to sense the electronic apparatus and generate sensing information, such that the processor 10 may obtain a position where the electronic apparatus is located according to the sensing information. In the present exemplary embodiment, the sensor 16 may include at least one of an image capturing device, an infrared sensing device, a signal strength sensing device and a touch sensing device.
In the present exemplary embodiment, the wireless charging system 1000 further includes a storage unit (which is not shown). The storage unit stores a plurality of program code segments, and the program code segment, after being installed, are executed by the processor 10. For example, the storage unit may include a plurality of modules and various operations to be applied in the wireless charging system 1000 are respectively performed through these modules, where each of the modules is composed of one or a plurality of program code segments. However, the invention is not limited thereto, and each of the operations of the wireless charging system 1000 may be performed by implementation in other hardware forms.
Particularly, referring to
In addition, in an exemplary embodiment, the electronic apparatus 20 may also send charging information to trigger the aforementioned process before the charging operation. The processor 10 may control the sensor 16 to sense the electronic apparatus 10 according to the charging information to obtain the sensing information, such that the processor 10 may determine the position on the placement platform 100 where the electronic apparatus 10 is placed according to the sensing information.
Several embodiments are provided below to describe in detail how the processor 10 determines the position on the placement platform 100 where the electronic apparatus 10 is placed according to the sensing information.
In an embodiment, the sensor 10 may include at least one image capturing device. The image capturing device is, for example, a video camera or a camera using a charge coupled device (CCD) lens, a complementary metal oxide semiconductor transistors (CMOS) lens or an infrared lens. The image capturing device may be disposed, for example, directly above, obliquely above the placement platform 100 or at an edge of the placement platform 100, which is not limited herein.
The image capturing device may photograph the placement platform 100 to capture an image (which is also referred to as a first image) having the electronic apparatus 20. The processor 10 may perform object recognition according to the first image to obtain the position 70 on the placement plane of the placement platform 100 for placing the electronic apparatus 20.

However, in another embodiment, the moving platform 12 may not first move the signal strength sensing device. When the electronic apparatus 20 sends the charging information, the processor 10 may generate a control signal according to the charging information, the moving platform 12 may then move the signal strength sensing device according to the control signal to sense the electronic apparatus 20 on the placement platform 100 that requires to be charged.
In another embodiment, the sensor 16 may include at least one touch sensor. The touch sensor may be used to detect at least one touch on the placement platform. For example, the user may touch the position 70 on the placement plane of the placement platform 100 by a hand. In this circumstance, the touch sensor may sense the touch of the position 70 on the placement plane. The touch sensor may send a touch sensing signal according to the touch. The processor 10 may obtain where the position 70 is according to the touch sensing signal. Thereafter, the processor 10 may send a control signal according to the obtained position 70. The moving platform 12 may, according to the control signal, move the wireless charging apparatus 14 to the position 70 near the electronic apparatus 20, such that the wireless charging apparatus 14 may wirelessly charge the electronic apparatus 20.
