Description

Counter {Counter}

The present invention relates to a counter, and more particularly, to a counter that accurately counts the number of first or second operations that a subject repeats without any additional manipulation.

In general, counters are instruments used to count the number of items or persons or the number of times a certain action is repeated.

On the other hand, in Buddhism, Oceugiji is a means of practicing one's devotion to honor and return to the three treasures of Bubo, Jumbo, and Seungbo, while at the same time pursuing their own minds. Repeat the same verse as in

At this time, the number of repetitions of the stanza is usually 108 times, 1080 times, and 3000 times, so it is impossible for the attendant to count them directly. After making a certain number of times, the beads are counted by hand or by the people around them. This has been used. However, since these methods depend entirely on human power, they become less reliable as the number of iterations increases.

Therefore, various types of counters are used. For example, a manual counter that operates the decimal counter mechanism by hand every time is placed on the floor and counted while pressing each time, or pressure is detected on the cushion. There are a method of counting the number of cuts through the change in pressure applied to the sensor, and a method of using a pedometer with a horizontal sensor mounted in view of the upper body tilting each time the cut is performed.

However, the method of using a manual counter placed on the floor requires additional operations such as pressing by the attendant, so that the number of clauses increases physically, and the reliability depends on the performer's operation. In addition, the method of utilizing the pressure change applied to the cushion is cumbersome that the attendant must be seated at the correct point every time the bow is performed, otherwise counting is impossible.

Lastly, when using a pedometer with a built-in horizontal sensor, it is difficult to accurately measure because it counts unnecessary motions in the deformed motion such as the high doubling.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a counter that can more accurately count the number of times the first or second operation is repeated by the subject as described in the section.

1 is a block diagram illustrating a schematic structure of a counter according to the present invention. The light emitting unit 10 irradiates infrared rays to a subject 80 and a light receiving unit receiving infrared rays reflected from the subject 80. 12), a central processing unit (25) for detecting whether the first or second operation of the subject 80 is counted based on the amount of infrared rays received from the light receiving unit 20, and counting the number of times; And a display unit 30 for displaying the counting result to the user who is the subject 80, a control unit 35 for controlling the operation of each component, and a power supply unit 40 for supplying driving power.

Hereinafter, each element will be described in more detail.

First, the light emitting unit 10 includes an infrared ray source 12 emitting infrared rays and a modulator 14 irradiating the object 80 by appropriately adjusting the amount and wavelength of infrared rays emitted by the infrared ray source 12, wherein the subject Infrared radiation irradiated at 80 is preferably a near infrared wavelength (Short Wavelength Infrared Range) corresponding to a wavelength band of 0.75 to 3 µm.

The infrared light source 12 may be an infrared light emitting diode or the like, and the modulator 14 may include an interference filter, a dichroic mirror, a collimator, or a plurality of lenses according to the purpose. can do.

In addition, the light receiver 20 may include an infrared sensor 22 and an amplifier 24. The infrared sensor 22 may generate analog signals having different sizes according to the amount of infrared rays reflected from the subject 80. A diode or a photoconductive element may be used, and the amplifier 24 may use a comparator such as an OP-AMP for converting an analog signal generated by the infrared sensor 22 into a digital voltage within a predetermined range.

Of course, the lens or interference filter may be included in the light receiving unit 20 according to other purposes.

On the other hand, as described above, since the subject 80 repeats the first operation of lifting the body and the second operation of bending the body, the amount of infrared rays received by the light receiving unit 20 during the first operation and the second operation are repeated. The amount of infrared light received at the time is different from each other, and the magnitude of the digital voltage applied to the central processing unit 25 through the infrared sensor 22 and the amplifier 24 is also different.

Therefore, the CPU 25 detects whether the first or second operation of the subject 80 is performed according to the magnitude of the digital voltage, and counts the number of times. At this time, it is apparent to those skilled in the art that the CPU 25 may serve as the amplifier 24 of the light receiving unit 20 according to the purpose.
