Abstract
The invention discloses a self-adaptive speed regulation circuit of a running machine. A heart sound microphone installed on the chest of a runner is used for extracting human body heart rate signals of the runner and is connected with a microprocessor through a signal processing circuit, and the power control output end of the microprocessor is connected with a motor control circuit. By the adoption of the technical scheme, the speed of the running machine can be automatically adjusted according to the heart rate conditions of the runner, and therefore the runner can scientifically and safely participate in national fitness activities.
Description
Technical field
The present invention relates to a kind of alignment circuit, particularly a kind of circuit that carries out speed governing according to runner's heart rate situation.
Background technology
Existing treadmill speed governing needs runner manually to regulate, and when runner feels tired, due to treadmill excessive velocities, reduction of speed operation is more difficult, sometimes also can cause unnecessary damage to health.Also have some treadmills can determine according to the dynamics of runner's step the speed of treadmill, but because human body has the tired process lagging behind, there is the overtired of a period of time in health before treadmill reduction of speed, to health, also can cause certain injury.And heart rate is the index that human-body fatigue is the sensitiveest, be necessary to using that this is as the definite intensity of taking exercise of index.
Summary of the invention
Goal of the invention of the present invention is a kind of treadmill adaptive speed regulation circuit that carries out speed governing according to runner's heart rate situation of design, and its concrete technical scheme is:
A kind of treadmill adaptive speed regulation circuit, hear sounds microphone is connected with the input of the first amplifier by shielding line, resistance R 3, the be connected in parallel output of the first amplifier of capacitor C 1, the other end of resistance R 3 connects positive input terminal and the capacitor C 3 of the second amplifier, capacitor C 1, capacitor C 2 and capacitor C 3 series connection, one end of resistance R 1 is connected with capacitor C 2 with capacitor C 1, the other end of resistance R 1 is connected with one end of potentiometer P2, one end of resistance R 2 and capacitor C 2, capacitor C 3 connects, the other end of resistance R 2 is connected with the other end of potentiometer P2, the adjustable end of potentiometer P2 is connected with output with the negative input end of the 3rd amplifier, the positive input terminal of the 3rd amplifier is connected with the adjustable end of potentiometer P1, one end ground connection of potentiometer P1, the negative input end of the other end and the second amplifier, output connects, the output of the second amplifier is connected with bandpass filter input, the output of bandpass filter connects microprocessor through A/D converter, microprocessor power control output end connects circuit for controlling motor.
Further, described microprocessor is C51 single-chip microcomputer.
Adopt technique scheme, treadmill can regulate treadmill speed automatically according to runner's heart rate situation, makes runner's participation national fitness campaign of science, safety more.
