A wireless charging system includes a wireless charging device and a power-consuming device installed in a charging area. The wireless charging device has a signal conversion module connected to a controller, a transmitter antenna and a power input terminal. The power-consuming device has a receiver coil connected to a rectifier and outputting generated power through a power output terminal. Before or when the wireless charging device charges the power-consuming device, the controller of the wireless charging device can detect a power consumption status, voltage and current information and phase difference information of the transmitter antenna to instantly determine if any foreign metal object enters the charging area, thereby preventing high temperature generated by the foreign metal object from causing equipment damage and danger and enhancing wireless charging safety.
