Intelligent automatic variable speed control system of bicycle

Abstract

The invention discloses an intelligent automatic variable speed control system of a bicycle. The intelligent automatic variable speed control system of a bicycle includes a speed changer, a detection module, a neural network module, and a variable speed control module, wherein the detection module is used for detecting the physical condition of a rider and the bicycle condition, and generating a physical condition signal and a bicycle condition signal; the neural network module is provided with a calculating model which is formed through sample data training; the calculating model is used for acquiring the physical condition signal and the bicycle condition signal and then obtaining a speed changing signal of the current bicycle through calculation, and at the same time, the calculating model is updated by means of the physical condition signal and the bicycle condition signal; and the variable speed control module is used for controlling speed changing of the speed changer according to the speed changing signal. The intelligent automatic variable speed control system of a bicycle integrates the data of bicycle with the data of human body to realize automatic intelligent accurate speed changing through calculation and analysis, and has the advantages of improving riding balance, improving riding safety, and greatly improving the riding experience; and the intelligent automatic variable speed control system of a bicycle provides an automatic gear shifting strategy of a BP neural network, and can preferably solve the optimum shift identification problem, and can timely and accurately satisfy the requirement for automatic speed changing of the bicycle.

Description

technical field [0001] The invention relates to the technical field of bicycle speed change control, in particular to an intelligent automatic speed change control system for bicycles. Background technique [0002] Today, many years have passed since mountain bikes were introduced into China. As time goes by, bicycles have become more advanced, more professional, and of course more expensive; in recent years, due to everyone’s awareness of environmental protection and health awareness With the increase of the number of people, cycling has gradually become a kind of entertainment and hobby for everyone. With the development of economy and technology, people pay more and more attention to health and sports, and users' demand for bicycles is shifting from traditional means of transportation to multifunctional bicycles for sports, fitness, tourism and leisure. Cycling is becoming more and more popular, and the service needs of cyclists in the process of riding tend to be divers...

AI Technical Summary

Problems solved by technology

There are inevitably some problems with the rear derailleur using cables: 1. The structure is complex and the manufacturing cost is high; 2. A large force is required when shifting gears, especially when the force is low or uphill. , the rider shifts gears vigorously, which also brings complete hidden dangers to the riding balance; 3. Using the cable control method, it is generally impossible to achieve continuous gear shifting, and the riding experience is poor

[0005] However, the above method cannot accurately reflect the speed change situation that people currently need, and the intelligence is still not high.
