Abstract

The present invention relates to a speedometer for running using the Hall element and wireless communication. According to the present invention, a radio wave emitting unit (a radio wave emitting unit is composed of a Hall element, an MPU, and a VHF antenna) and thus generated radio waves detects an emitter generating a magnetic field and a magnetic field and converts and transmits the detected magnetic field into an electric signal It is divided into a control unit (receiving the radio wave receiving VHF antenna and MPU) and an output unit (output unit adds a function to the existing clock) for receiving and calculating.

Thus, the present invention consists of three parts. It can detect the magnetic field placed at a certain distance and calculate the speed by dividing the measured distance by time, and also know the distance and calories. It is a clock-based speedometer that can make the movement fun and efficient.

Also, if you move with a magnetic field generator (magnet) on the other foot, you can calculate speed and distance if you know our average stride length.

Description

Running mate

It is a device for detecting magnetism using hall elements and a wireless communication technology for converting and transmitting the sensed magnetism into radio waves.

In addition, it is an arithmetic unit that calculates a radio signal by a microprocessor and an output device that is visible to our eyes through liquid crystal.

According to the present invention, by visually showing the distance and speed and calories we exercise, it increases the efficiency of the exercise, and serves to help the fun exercise.

Hereinafter, the structure of the invention according to the present invention will be described with reference to the drawings.

1 shows a magnetic scaffold installed at a constant distance.

2 is a discharge unit for emitting magnetism, a transmitter and receiver for sensing magnetism and transmitting radio waves, and an output device;

3 shows a magnetic field in the radio wave transmitter when passing on a magnetic footboard while wearing a transmitter.

As shown in Fig. 5, the received radio waves calculate the distance, calorie average speed, etc. by the computing device. For example, if the magnetic pads are installed at intervals of 100 m, each time the athlete passes over the magnetic pad, the accumulated signal is continuously timed, the distance is calculated, and the average speed is calculated by the processor.

Average speed:

V (m / sec) = (Σ100 × N) × t

               Where N is the number of detected magnetic fields

                        t is the accumulated time

6 and 7 may measure the average stride length of the exerciser when there is no magnetic pad and detect the magnetic field installed on the other ankle using the measured value to obtain the average speed.

Average speed:

V (m / sec) = (ΣL × N) × t

               Where L is the average stride of the individual

                       N is the number of magnetic fields detected

                       t is the cumulative time

FIG. 8 is a block diagram showing a transmitter and shows a process of sensing magnetism using a Hall element and transmitting the sensed magnetism as a radio wave; FIG.

FIG. 9 is a block diagram illustrating a flow in which a radio wave transmitted from a transmitter is received through a receiver and calculated by a microprocessor and then visually output.

According to the present invention, the athlete can improve the fun and efficiency of the exercise by visually recognizing the speed and calories, such as a treadmill indoors while exercising outdoors. And using the pre-measured average stride length, the same effect can be achieved where no magnetic pad is installed.
