Abstract

The invention relates to the field of foreign matter detection, and discloses a foreign matter detection method, a control device, a radar detection device and system. The foreign matter detection method is applied to the control device, the control device is in communication connection with the radar detection device, and the radar detection device is arranged on a primary side or a secondary side in a wireless power transmission system. When the radar detection device is arranged on the primary side, the antenna of the radar detection device faces the secondary side coil, and when the radar detection device is arranged on the secondary side, the antenna of the radar detection device faces the primary side coil.The foreign matter detection method comprises the following steps: firstly, acquiring a detection signal of a radar detection device, and determining whether foreign matters exist between the primary coil and the secondary coil or not according to the detection signal. Therefore, the foreign matter detection method can effectively detect the foreign matter invasion condition between the primary side coil and the secondary side coil of the wireless electric energy transmission system, so that the wireless electric energy transmission system is safer, and the cost is lower.

Description

technical field [0001] The invention relates to the field of foreign object detection, in particular to a foreign object detection method, a control device, a radar detection device and a system. Background technique [0002] Wireless Power Transmission (WPT for short) technology is a technology for power transmission by means of electromagnetic fields or electromagnetic waves between its coils. In the entire space where the primary side coil and the secondary side coil are used for power transmission, if there is a foreign object, it will have a great impact on the wireless power transmission system and affect its safety. If the foreign object is metal, it will not only affect the power transmission, but more importantly, under the high power transmission, the metal is in the alternating magnetic field, and the temperature will rise. If the safe temperature is exceeded, it will cause a safety hazard. If there is a living foreign body, electromagnetic radiation will affect ...
