By means of its wireless communication technology, it plays a decisive role in many fields such as car starting, smart home control and access control, etc. This innovative device or system not only improves the convenience of life, but also further enhances security and efficiency.

[0033] To meet the application requirements in different scenarios, the types of wireless keys are also very diverse, including: radio frequency identification (RFID) key, Bluetooth key, infrared remote control key, ultra-wideband (UWB) key, etc. Specifically, Bluetooth key, infrared remote control key and ultra-wideband (UWB) key rely on battery and other energy storage modules for power supply through built-in power supply modules to ensure the continuous and stable wireless communication function, realize long-distance identity authentication or control operation, which undoubtedly improves the user experience. However, this power supply method also brings a potential problem: once the energy storage module is out of power, the wireless key will lose its due function, making the user fall into an embarrassing situation of being unable to open the door.

[0034] Although radio frequency identification (RFID) key does not need to be powered, it must be close to the pre-set radio frequency identification unit near the door lock to realize door opening, which is less convenient.

The above scheme, when the user needs to use the remote sensing key, the wireless reverse charging function of the mobile terminal can be turned on, at this time the wireless charging module in the remote sensing key will respond to the function to generate a corresponding voltage, the power supply module will stabilize and provide the voltage output by the wireless charging module to the wireless communication module, so as to send the corresponding signal of the remote sensing key through the wireless communication module to realize the corresponding unlocking operation, without using the power supply of the key itself, the remote wireless unlocking operation can be realized at any time, and the reliability of the remote sensing key is improved.

[0052] In the embodiment of the application, the remote sensing key only works when it needs to be powered, and stops running after the reverse charging is turned off, avoiding unnecessary consumption of the power supply during standby of the remote sensing key.

[0053] Optionally, in the embodiment of the application, when the remote sensing key is in a working state, a light touch switch in the remote sensing key is touched to make the wireless communication module enter a pairing state.

[0054] When the wireless communication module enters the pairing state, it can establish a one-to-one secure connection with an intelligent lock, a vehicle-mounted system or the like. That is to say, the remote sensing key involved in the embodiment of the application not only has the traditional unlocking function, but also provides a convenient pairing function when it is used for the first time or when the device is switched, bringing the user a more flexible and personalized use experience.

[0055] Optionally, in order to further improve the convenience and safety of use, the embodiment of the application also designs an intelligent detection function, which detects the working state of the wireless charging module of the remote sensing key through the mobile terminal when the reverse charging function of the mobile terminal is turned on.

[0058] Further, the mobile terminal is not used to open the remote sensing key by default after opening the reverse charging function, but only when the remote sensing key is attached to the reverse charging function area of the mobile terminal, the judgment of whether the remote sensing key function is abnormal is performed. Specifically, when the user opens the reverse charging function, a selection control appears on the interface of the mobile terminal, to directly prompt the user to confirm whether the reverse charging function is used to power the remote sensing key at this time; only when the user actively triggers the selection control, it indicates that the user confirms that the reverse charging function of the mobile terminal at this time is used to power the remote sensing key to activate the remote sensing key, and the mobile terminal will detect the power consumption of the wireless charging module of the remote sensing key. This design not only avoids the trouble caused by misoperation, but also further improves the convenience and safety of use.
