Embodiment Construction

[0036] The system and method for finding a mobile phone of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] The realization of the present invention is based on NFC (Near Field Communication, ie, short-distance wireless communication) technology. NFC can realize wireless interconnection between electronic devices, and its principle is to exchange information over short distances by exchanging electromagnetic wave signals between electronic devices.

[0038] NFC technology has attracted more and more attention in recent years because of its security features and non-contact communication. For example, existing mobile terminal equipment manufacturers have successively embedded NFC technology in the mobile terminal, that is, adding a first NFC module on the PCB board of the mobile terminal. The first NFC module is provided with an NFC antenna, and the NFC antenna is used for transmitting electromagnetic wave signals,...

Abstract

The invention provides a system for searching a mobile phone, which comprises a first device independent from the mobile phone, and the mobile phone comprises a starting up circuit and a first NFC (Near Field Communication) module transmitting NFC data with the first device, wherein the first device is used for storing identification information; and the first NFC module is used for reading and judging the identification information. If the identification information is correct, a horn of the mobile phone is started. The invention also provides a searching method for the system. The starting up circuit includes an N-channel metal oxide semiconductor (NMOS) field effect tube and a resistant upward pulling branch. A grid of the NMOS filed effect tube is connected to an output end of the first NFC module. A drain of the NMOS field effect tube, on one hand, is connected to the resistant upward pulling branch, on the other hand, is connected to the starting up circuit line of the mobile phone. A source of the NMOS field effect tube is connected to the ground. Through the system for searching the mobile phone, provided by the invention, the mobile phone can be found effectively.

Description

technical field [0001] The invention relates to the field of short-distance wireless communication, in particular to a method and system for finding a mobile phone. Background technique [0002] In the process of using mobile phones in daily life, it often happens that the mobile phone cannot be found. Generally, you can find a mobile phone by dialing the phone number of the mobile phone. [0003] However, the above methods have certain limitations. For example, when the mobile phone is turned off, the mobile phone cannot be found through the above methods. Contents of the invention [0004] The object of the present invention is to provide an effective method and system for finding a mobile phone. [0005] The purpose of the present invention is achieved like this: [0006] A system for finding a mobile phone, which includes a first device independent of the mobile phone, the mobile phone includes a power-on circuit and a first NFC module for NFC data transmission wit...
