Problems solved by technology
Among them, the positioning range that can be realized by WiFi positioning technology is tens of meters to hundreds of meters, the positioning accuracy is too low, and its power consumption is large, which is easy to cause waste of power; while the positioning range of using NFC tag TAG technology is 4cm to 10cm , the positioning accuracy is relatively high, but because the effective sensing distance it can support is too small, it is necessary for the user to place the electronic device supporting near-field communication close to the preset NFC tag for a few centimeters to sense the positioning. The use of NFC positioning operation in a large space causes great inconvenience, and also restricts the wide application of NFC positioning technology in real life

The invention discloses a positioning method which is applied to an electronic device, and the electronic device has an FM receiving function. When the electronic device starts the FM receiving function, a first instruction is received; the first instruction is used for monitoring FM signals around the electronic device; the first instruction is responded, and FM signals within a certain range far away from the electronic device are monitored at a specified frequency band; when the FM signals are monitored, the mark information of an emitting source is resolved from the FM signals; the orientation of the FM signal emitting source is determined through the resolved marking information of the emitting source; the current position of the electronic device is corrected and positioned according to the orientation of the FM signal emitting source. The invention further discloses a positioning device and the electronic device. The positioning method, the positioning device and the electronic device can improve positioning accuracy and positioning correctness, and save the electricity quantity.
Description
technical field [0001] The invention relates to positioning technology, in particular to a positioning method, a positioning device and electronic equipment. Background technique [0002] At present, most electronic devices such as tablet computers and mobile terminals usually adopt wireless fidelity (WiFi, Wireless Fidelity) technology or near field communication (NFC, Near Field Communication) tag TAG technology to realize positioning. Among them, the positioning range that can be realized by WiFi positioning technology is tens of meters to hundreds of meters, the positioning accuracy is too low, and its power consumption is large, which is easy to cause waste of power; while the positioning range of using NFC tag TAG technology is 4cm to 10cm , the positioning accuracy is relatively high, but because the effective sensing distance it can support is too small, it is necessary for the user to place the electronic device supporting near-field communication close to the prese...
