Description

Wireless charging method and system thereof Technical Field The disclosure relates to a wireless charging method and a system thereof, and more particularly to a wireless charging method with a detection function and a system thereof. Background Prior wireless charging devices require detection of devices placed thereon to confirm the presence of foreign objects prior to or during power transmission. In addition, in the normal charging process, the existing wireless charging device must continuously test whether foreign matters exist and over-temperature conditions based on charging safety, and in addition, charging safety confirmation needs to be frequently carried out with a device arranged on the wireless charging device to confirm whether to continue charging or whether to adjust charging power and the like. Because the existing wireless charging device has simpler functions, the complete functions can be realized by sequentially executing foreign matter detection (Foreign Object Detection, FOD), over-temperature detection and wireless charging transmission (WIRELESS CHARGING TRANSMITTER, WCT) in turn in a software architecture. With the development of the market, wireless charging technology is rapidly developed, so that not only is the charging power requirement rapidly increased, but also the rapid charging technology is increasingly applied. And the future development direction will be towards the development of intelligence and multi-load. For example, the wireless charging device has a wireless charging function and can be used as a wireless communication interface of mobile equipment such as an automobile and a mobile phone. For example, a wireless charging apparatus may charge multiple devices simultaneously. When the wireless charging device charges a device placed thereon, it is not possible to confirm whether the device is a chargeable device, and thus wireless detection of the device needs to be performed at the same time. However, the time required for performing a complete test is much longer than the cycle time of the above-mentioned charge safety confirmation procedure, so when the time spent in the test is longer than the cycle time, the wireless charging device will be automatically turned off and restarted because no charge safety confirmation is performed or the communication interruption time is too long, and then the wireless charging is continued, so that the wireless charging is intermittent and the charging quality cannot be ensured. If the charging safety confirmation procedure is preferentially executed when the cycle time arrives, the complete wireless detection cannot be executed in real time, and if the device is not chargeable and is not detected in real time, the device is damaged due to continuous charging. Therefore, how to develop a wireless charging method and system thereof capable of improving the above prior art is an urgent need. Disclosure of Invention The disclosure provides a wireless charging method and a system thereof, which divide a task for executing wireless detection in a charging device into a plurality of detection subtasks and alternate the charging task to be executed in the plurality of detection subtasks. Therefore, wireless charging and wireless detection are simultaneously realized, so that charging quality is ensured, and the detection object is detected in real time to prevent the detection object from being damaged. The wireless charging method comprises the steps of (a) providing a charging device, wherein the charging device is provided with at least one charging area for the intelligent device to be placed, the charging device is configured to charge the intelligent device when executing a charging task, the charging task comprises at least one charging subtask, the charging device is configured to detect whether a detected object exists on the charging area when executing a detection task, the detection task comprises a plurality of detection subtasks, (b) executing a charging initialization program and a communication initialization program, and (c) executing a plurality of detection subtasks and at least one charging subtask, and the at least one charging subtask is executed in a penetrating manner in the plurality of detection subtasks. In accordance with the concepts of the present disclosure, a wireless charging system is provided that includes a charging device having at least one charging area for placement of an intelligent device. The charging device is configured to charge the intelligent device when executing a charging task, wherein the charging task comprises at least one charging subtask. The charging device is configured to detect whether a detection object is present on the charging area when a detection task is executed, wherein the detection task comprises a plurality of detection subtasks. At least one charging sub-task is interleaved among the plurality of detection sub-tasks. Drawings Fig. 1 is a schematic diagram of a
