Object seeking device and method based on mobile terminal

Abstract

The invention discloses an object seeking device and method based on a mobile terminal. The object seeking device comprises an active tag component and an inquiry unit, wherein the active tag part is connected with an object to be sought, and the inquiry unit is based on the mobile terminal. The active tag component is used for sending wireless signals. The inquiry unit based on the mobile terminal is used for detecting the wireless signals and determining the position of the active tag component. The seeking method includes the following steps that a first wires receiving and transmitting module transmits the wireless signals, a second wireless receiving and transmitting module detects the wireless signals, a second CPU determines the distance between the active tag component and the inquiry unit, and position variation between the active tag component and the inquiry unit based on the mobile terminal is displayed on a display screen. According to the object seeking device and method based on the mobile terminal, a user can visually and naturally seek the object that the user wants to seek with low cost.

Description

technical field [0001] The present invention relates to a small object searching device and a searching method, in particular to a small object searching device and a searching method based on a mobile terminal, such as a mobile phone, a tablet computer, etc. Changes in the orientation and relative displacement distance of the device. Background technique [0002] In daily life, people often forget or cannot find some objects such as keys and remote controls, which brings a lot of troubles to people's lives. Based on the above requirements, the present invention designs a device for finding small objects based on a mobile terminal. [0003] There are three solutions in the prior art: the first is a pair of wireless signal transceivers, the sending device is carried by the user, and the receiving device has a buzzer, which is bundled with the object to be found. When the user wants to find the lost object, the corresponding command is sent, and the receiving device emits a ...

Problems solved by technology

The second solution in the prior art is to use a wireless transceiver module to judge the distance of the object by checking the strength of the signal. This method ignores two problems. One is that if the antenna of the transmitting module is not isolated, once it touches a metal object , it will be difficult to have a signal for the receiving device to receive. Second, in the office or home environment, electromagnetic waves will be affected by multipath and reflection. In the process of users looking for objects, misjudgments will easily occur and the user experience will be poor.

The third is to find someone to whistle, and the buzzer will sound after the whistle response device bundled with the object to be found receives the whistle. The power consumption is large, the volume of the sound receiving device is large, and the third is that there is no measurement of relative position changes
