A sensor-based positioning method

Abstract

The invention discloses a sensor-based positioning method, comprising a wireless signal broadcasting device and a mobile electronic device. The wireless signal broadcasting device broadcasts a wireless signal within a wireless coverage range of the wireless signal broadcasting device. The mobile electronic device is provided with a motion sensor and a wireless communication module, wherein the user carries the mobile electronic device, the motion sensor of the mobile electronic device collects the related motion data, and the wireless module in the mobile electronic device searches and scans the wireless signal characteristics in the coverage area and matches the set value. Compared with the prior art, the sensor-based positioning method provided by the invention has the advantages of strong practicability, long service life, small environmental impact, easy popularization, favorable customer experience and high stability. A motion sensor is used to control the start or stop of the search unit of the wireless module on the mobile device, so that the search unit of the wireless module is avoided to be in a state of on-scan for a long time, and the power consumption is large.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a sensor-based positioning method. Background technique [0002] At present, wireless communication technology is widely used in electronic devices. Once the wireless connector in the electronic device is turned on, nearby wireless devices can be detected. For example, a smartphone will display the signal strength of nearby Bluetooth devices and devices after turning on Bluetooth . The search unit of the wireless module of the mobile electronic device can be maintained in a continuous scanning mode through program control. In this continuous scanning mode, the device searches for nearby available wireless signal devices and performs positioning. While use of continuous scan mode generally does not require user intervention, continuous scan mode can be highly power intensive, draining battery power and potentially shortening mobile device battery life. And after a long time ...
