Running speed detection and warning system

Abstract

The invention, which relates to the wearable electronic equipment field, discloses a running speed detection and warning system so that a problem that people run fast at the beginning and the runningspeed is reduced gradually with the physical decline when people do long-distance running to exercise the strength and endurance and thus the endurance can not be strengthened effective while the physical fatigue is alleviated can be solved. The system employs a single-chip microcomputer as the core; a ball type vibration sensor or a mercury switch is used for collecting vibration generated duringrunning of the runner and thus recording the running frequency; the running speed is calculated by combining the frequency with the step length and running time of the runner; when the running speedis lower than a set value, the single-chip microcomputer carries out warning by a buzzer, so that the runner keeps the original speed all the time and thus the endurance training effect is improved conveniently. The system having a simple structure causes no radio wave pollution; the low cost is low; and the system has the broad market prospects.

Description

technical field

[0001] The invention relates to the field of wearable electronic devices, in particular to a running speed detection and reminder system. Background technique

[0002] When people short-circuit their physical strength and endurance through long-distance running, they usually run faster at the beginning, and the running speed slowly decreases with the decline of physical strength. Although this can relieve physical strength, it does not affect endurance exercise. Not very effective. Contents of the invention

[0003] The present invention provides a running speed detection and reminder system, which is used to solve the problem that when people short-circuit their physical strength and endurance through long-distance running, they usually run faster at the beginning, and the running speed becomes slower unconsciously as their physical strength decreases. Slow down, although this can relieve physical strength, it is not very effective for endurance exercise....
