Anti-interference treadmill control circuit having compensation and automatic protection functions

Abstract

The invention discloses an anti-interference treadmill control circuit having compensation and automatic protection functions. The anti-interference treadmill control circuit is characterized by comprising an AC filtering circuit, a first rectification filtering circuit, a second rectification filtering circuit, a voltage reduction circuit, a controller circuit, a PWM control circuit and a speed measurement circuit, wherein the AC filtering circuit is connected with the commercial power and is then connected with the first rectification filtering circuit and the second rectification filtering circuit after eliminating interference signals of the commercial power, the commercial power supplies power for the PWM control circuit after passing through the first rectification filtering circuit, the PWM control circuit is connected with a motor and the speed measurement circuit and is then connected with an MCU, the first rectification filtering circuit is connected with the voltage reduction circuit and is then connected with the controller circuit and the MCU through the voltage reduction circuit, and the controller circuit is connected with the MCU. The anti-interference treadmill control circuit is advantaged in that the circuit is simplified, and safety of products is further improved.

Description

technical field [0001] The invention relates to a circuit on a treadmill, in particular to a treadmill control circuit with anti-interference compensation and automatic protection functions. Background technique [0002] The electric treadmill is a relatively high-end equipment for gyms and families. It drives the running belt through a motor to make people run or walk passively at different speeds. Due to the passive formation of running and walking, it is almost the same as running or walking on the ground from the perspective of movement shape, but from the perspective of human body strength, running and walking on the electric treadmill saves a pedal stretch compared with ordinary running and walking. action. It is this point that makes every person who walks and runs on the electric treadmill feel very relaxed, which can make people run about 1 / 3 more than ordinary running, and consume more energy than ordinary walking and running. [0003] There are many treadmill pr...

AI Technical Summary

Problems solved by technology

[0003] There are many treadmill products on the market, so the control circuits of treadmills are not rare, and there are many with protection functions similar to this design, but basically the control circuits with such functions are more complicated. , bulky, relatively heavy, greatly increasing the cost and production difficulty, and some relatively simple designs do not have these protection functions, sacrificing the safety performance of the product, and there is no guarantee for the safety of users
