Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] figure 1 It is a flow chart of a method for testing motion speed provided by an embodiment of the present invention, and the method includes:

[0043] S100, measure the static pressure P of the inner cavity of the pressure hole of the mobile device 0 ; The pressure hole communicates with the outside world, and is provided separately or as an existing design opening on the mobile device.

[0044] Wherein, the mobile device may be a mobile phone, a wearable device, and the like.

[0045] Because the cross-sectional area of ​​the inner cavity of the pressure hole is too large, the wind resistance will be affected, which will further affect the accuracy of the speed test. In practical applications, the inner diameter of the inner...

Abstract

The invention discloses a method and device for testing movement speed. The method includes the steps: measuring static pressure P0 of an inner cavity of a pressure hole of a mobile device; individually forming an opening or a designed opening in the mobile device; aligning the pressure hole to the wind direction, and measuring total pressure P of wind in the static state; aligning the pressure hole to the wind direction in the moving process, and measuring the pressure Pm of the inner cavity of the pressure hole in the movement direction; acquiring current wind speed vf according to the corresponding relationship between the wind speed vf and movable pressure P-P0; acquiring current relative movement speed vr according to the corresponding relationship between relative movement speed vr and pressure difference Pm-P0; acquiring current movement speed v according to the current relative movement speed vr and the current wind speed vf. The pressure hole is communicated with the outside. The movement speed can be rapidly acquired, testing results are accurate and reliable, and the technical scheme is completely different from a scheme of testing the movement speed by a GPS (global positioning system) in the prior art.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method and equipment for testing motion speed. Background technique [0002] Existing mobile phones and wearable devices usually use GPS navigation and positioning, and calculate the movement speed according to the positioning results. However, this method of testing motion speed by means of GPS is limited by the quality of the GPS signal. If the quality of the GPS signal is not good, the accuracy of the measured motion speed is poor; reliable. Contents of the invention [0003] The invention provides to solve the problems of poor precision and unreliable calculation results of using GPS to test the motion speed in the prior art. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] On the one hand, the embodiment of the present invention provides a kind of testing method of motion speed, and d...
