[0046] refer to figure 1 , the first embodiment of the positioning method of the present invention is proposed, and the method includes the following steps:

[0047] S11. Detect whether the positioning signal of the satellite positioning system is normal. When the positioning signal is abnormal, go to step S12.

[0048] In the embodiment of the present invention, a PDR (Pedestrian Dead Reckoning, Pedestrian Dead Reckoning) unit is added to the smart watch. After the smart watch starts the satellite positioning system, the PDR unit can be initialized immediately. Preferably, the PDR unit will enter low power consumption after initialization is completed. state (such as sleep state, sleep state, etc.) to save power. Optionally, the PDR unit includes a nine-axis sensor and a corresponding processing unit, and the processing unit is preferably an MCU (Microcontroller Unit, micro control unit).

[0059] refer to figure 2 , propose the second embodiment of the positioning method of the present invention, the method includes the following steps:

[0060] S21. Detect whether the positioning signal of the satellite positioning system is normal. When the positioning signal is abnormal, go to step S22.

[0061] S22. Obtain position offset data through the PDR unit, and reduce the working frequency of the satellite positioning system.

[0062] S23. Calculate current positioning data according to the latest effective positioning data and position offset data.

[0063] S24. When the positioning signal of the satellite system returns to normal, restore the working frequency of the satellite positioning system.

[0064] In this embodiment, when the positioning signal is not normal, the operating frequency of the satellite positioning system is also reduced while obtaining the position offset data through the PDR unit, preferably the operating frequency of the satellite positi...

Abstract

The invention discloses a positioning method, a device and an intelligent watch. The method comprises the following steps: detecting whether a positioning signal of a satellite positioning system is normal or not; when the positioning signal is not normal, obtaining position offset data through a PDR unit; calculating to obtain current positioning data according to most recent effective positioning data and the above offset data. In this way, the satellite positioning mode is switched to the PDR positioning mode in the weak signal strength condition of the satellite positioning signal of the satellite positioning system. As a result, the accurate positioning function of the intelligent watch can also be realized in a severe environment. The technical problem that the positioning of the intelligent watch cannot be realized or is poor in accuracy in a weak signal strength condition of positioning signals can be solved. The integrity and the precision of the positioning path of the intelligent watch are effectively improved. During the PDR positioning process, the working frequency of the satellite positioning system is reduced, and the meaningless power consumption of the system is reduced. Therefore, the power consumption of the intelligent watch is greatly reduced, and the standby time is prolonged.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a positioning method, device and smart watch. Background technique [0002] With the development of wireless communication technology, smart wearable devices are gradually favored by people, among which smart watches are the most mature. Smart watches can not only indicate time, but also have functions such as navigation, calibration, and reminders, and even support interconnection with other smart devices, such as interconnection with smartphones, and support some functions of smartphones, such as WeChat message reminders, incoming call reminders, and viewing text messages , check email, check schedule and other functions, it can be seen that the application scenarios of smart watches are very broad. [0003] The smart watch uses the satellite positioning system for positioning and navigation. In some environments, such as under a bridge hole or in the woods, the po...
