Electronic equipment positioning system, method and device

Abstract

The embodiment of the invention discloses an electronic device positioning system which comprises a positioning device and a device to be searched, the device to be searched is in communication connection with the positioning device, and the device to be searched can broadcast radio frequency signals outwards through a single antenna. Double antennas are arranged on the positioning device, and thepositioning device can periodically switch the double antennas to receive radio frequency signals. Orthogonal sampling is performed on the radio frequency signals received by the double antennas so as to acquire the phase difference of the double antennas; according to the phase difference, the distance value between the two antennas and the radio frequency wavelength, the deviation angle betweenthe to-be-searched device and the positioning device can be calculated, so that the position direction of the to-be-searched device is determined. The scheme is based on wireless communication and amulti-radio-frequency antenna technology, accurate positioning of the electronic equipment in a short-distance range can be realized, and the defect that various existing outdoor anti-lost technologies cannot perform indoor short-distance range positioning is overcome. The embodiment of the invention further provides an electronic equipment positioning method and device, and the effects are as described above.

Description

technical field [0001] The invention relates to the technical field of equipment positioning, in particular to an electronic equipment positioning system, method and device. Background technique [0002] With the improvement of the intelligent level of electronic equipment, in addition to the improvement of performance, many electronic equipment have a more refined and beautiful appearance, and the size is getting smaller and smaller, which is more convenient for users to carry and use. [0003] Taking Bluetooth headsets as an example, wireless Bluetooth headsets have become the mainstream and hot spot in the development of Bluetooth headsets. However, due to their independent ears, the easy loss of the headset has become a pain point of the product. There are many methods for outdoor positioning of wireless bluetooth headsets, such as GPS positioning, but the existing positioning methods are generally with an accuracy of a few meters, such as positioning in a building, but ...

Problems solved by technology

There are many methods for outdoor positioning of wireless Bluetooth headsets, such as GPS positioning, but the existing positioning methods are generally with an accuracy of a few meters, such as positioning in a building, but there is nothing you can do about the specific orientation in the building

There is still no effective method for short-distance indoor positioning
