Abstract

DC60 (22/11/56) This invention relates to a system for measuring the amount of energy metabolism of the body. From cycling It consists of a transmitter (1) a sensor (2) a keypad (3) a microcontroller (Microcontroller) Display (Display) (10) and bicycles, where the microcontroller type controller. (Microcontroller) has a microprocessor. (Microprocessor) (8) serves to process data. To indicate the amount of energy metabolism of the body from cycling Based on information It was obtained by considering the relationship of the force acting on the pedals transmitted by the bicycle mechanics that consisted of the pedals, bicycle crankset, chain sprocket, front chain sprocket, rear sprocket, front wheel. And the rear bicycle wheel until the point of contact between the rear wheels of The bicycle connects the rear axle to the road. Taking into account the stiffness of the road surface in order to obtain the amount of burning Actually burns the energy generated from cycling The invention involved a system to measure how much energy the body burns from cycling, consisting of a microcontroller. (microprocessor) at the counting circuit Set time (Timer / Conter) and microprocessor (microprocessor) for processing. Data with the Department for calculating data received from detectors, signals (Sensor) and data buttons by processing the calculation equation for the amount of energy burned. Mechanical Cycling and transmitting the results to the display By the quantity measurement system How the body burns energy from cycling According to this production Have considered the relationship Things that are acted on the bicycle pedals and transmitted through the bicycle riding mechanism Until reaching the point of contact Between the rear bicycle wheel and the road to achieve the metabolic rate that arises from Actually ride a bike

Claims (1)

Disclaimers (all) that will not appear on the advertisement page: 1. A system to measure the amount of energy the body burns from cycling, consisting of a microprocessor, electrically connected to a sensor Measure the wheel speed (Speed sensor) through the transmission line. Where the wheel speed sensor (speed sensor) consists of The transmitter (Transmiter) is mounted on the wheel or The spokes of the machine and the receiver (Receiver) are located on the fork of the bicycle. When the transmitter has passed the receiver for 1 cycle, the measured cycle count data. Will be recorded at the microprocessor (microprocessor) to be used to calculate the distance. Obtained from cycling There are a number of input buttons. For input to microprocessor (microprocessor) where the input button is electrically connected to the control circuit powder and the control circuit powder. It is electrically connected to the microprocessor. There is a display that is electrically connected to the microprocessor for It shows the results of time, speed, distance and amount of energy metabolism of the body. From cycling There is a unique The data entry button consists of a push button (1) for a device on-off switch. Keypad (2) for Increase the weight of the cyclist Push button (3) for reducing the weight of the cyclist. Push button (4) to confirm the data value. Push button (5) to start displaying information on the display screen. And pushbutton (6) to stop displaying information on the display screen. The microprocessor calculates the work value (W) obtained from cycling and turns it into the amount of energy burned.The unit of measurement is Calorie C as in the equation. W = 0.239 U x SX gx, where U is the coefficient of static friction, S is the distance the bicycle is traveled, g is the acceleration due to gravity of the earth, r1 is the radius of the front chain tooth, r0 is the length of the crank arm. mm is the mass of the cyclist, mn is the mass of the bicycle.
