Ladder management method based on step frequency trigger

Abstract

The present invention relates to a ladder management method based on stride frequency triggering. The method comprises the steps of: operating pressure detection devices arranged on pedals of a ladderto detect whether the pressures on corresponding pedals exceed the maximum bearing pressure or not, and emitting pressure alarm signals when the pressures on the corresponding pedals exceed the maximum bearing pressure; and operating a stride frequency detection device arranged on the ladder and consisting of a speech recognition chip, a microcontroller and a data output interface, wherein the speech recognition chip is configured to detect pedal sound emitted when personnel step on the pedals in the sound near the ladder to output detected time of detection of the pedal sound each time, andthe microcontroller is configured to determine each pedal step-on consumption time based on the time between each two adjacent pedal sound and determine average pedal step-on consumption time based oneach pedal step-on consumption time.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a ladder management method based on step frequency triggering. Background technique [0002] Ladders are one of the most commonly used tools. The preparations before use include the following items: 1. Make sure that all rivets, bolts, nuts and moving parts are tightly connected, the ladder columns and steps are firm and reliable, the circlips are stretched, and the working condition is good; 2. The ladder is kept clean, free of grease, Oil stains, wet paint, mud, snow and other slippery substances; 3. The operator's shoes should be kept clean, and leather-soled shoes are prohibited. [0003] The ladder structure design in the prior art is simple and rough. For example, since the ladder includes a plurality of parallel pedals, the distance between any two pedals is fixed during design, regardless of the age of the person using the ladder. Like this, resulting in For children, the dist...

[0003] The ladder structure design in the prior art is simple and rough. For example, since the ladder includes a plurality of parallel pedals, the distance between any two pedals is fixed during design, regardless of the age of the person using the ladder. Like this, resulting in For children, the distance between the pedals is too large, it is difficult to climb, and it is easy to cause danger, while for adults, the distance between the pedals is too small, too many times of climbing, easy to cause damage to the knees
