Height measurement method

The invention relates to a height measuring method, in particular to a method which is not only simple and convenient in its overall structural composition, but also relatively low in manufacturing cost, and is more convenient and more accurate in operation and use. An innovative designer of the height measurement method that measures the height value and adds more practical effects to its overall performance.

Press, the traditional height of the height machine, because of its large size, cumbersome, and more space, so that it is usually only visible in the medical field, and in the average family to measure the height, it is generally attached to the wall. The surface is marked or attached with a measuring scale for simple measurement of height, but it causes cleaning and aesthetic problems on the wall.

Therefore, there has been developed a "microcomputer-free measuring rod height measuring cap" disclosed on December 16, 1999, which is provided with a cap body having a cap and a cap. The main body of the cap body is provided with: a microcomputer control device for controlling the operation of all functions of the cap body; and a buzzer connected to the microcomputer control device for sounding the main body of the warning cap The level detection device is connected to the microcomputer control device, and detects whether the cap body reaches the level. If the level is not up, a sound signal is transmitted to the microcomputer control device, so that the microcomputer control device controls the bee. The beep sounds to alert the cap owner The body is not in a horizontal state; an ultrasonic transmitting device and an ultrasonic receiving device are disposed on the cap of the cap body, so that the cap extends the ultrasonic emitting device and the ultrasonic receiving device outward, so that the detecting is free from physical interference. The ultrasonic transmitting device and the ultrasonic receiving device are connected to the microcomputer control device, and the microcomputer control device can control the ultrasonic transmitting device to emit the ultrasonic wave, and operate the ultrasonic receiving device to receive the retroreflected ultrasonic wave, and calculate the ultrasonic wave from The time difference between the ultrasonic transmitting device and the ultrasonic receiving device, and the height data of the user is obtained by converting the time difference; the liquid crystal display device is connected to the microcomputer control device, so that the microcomputer control device can obtain the The height data is displayed on the liquid crystal display device.

However, although the above-mentioned "microcomputer without measuring rod height measuring cap" can achieve the expected effect of the user's height measurement, it is also found that the structure is extremely complicated in its overall structural composition, and the manufacturing cost thereof cannot be effectively reduced. And it needs to control the horizontal state firstly in operation and use, and then emit ultrasonic waves to the ground to calculate the height data of the user after receiving the retroreflected ultrasonic signal, resulting in the operation not only in the process of measuring the height Inconvenience, and the height measurement error range of the ultrasonic wave is large, and the measured height data is less accurate, so that there is still room for improvement in the overall structural design.

The reason is that the inventor has been rich in design and development and practical production experience of the relevant industry for many years, and has researched and improved the existing structure to provide a method for measuring the height and height, in order to achieve better practical value.

The height measuring method of the present invention is mainly for a height controller having a built-in analog digital (AD) converter, the microcontroller is connected with a three-axis sensor, and the input is connected to the microcontroller. a device, and a display device connected to the microcontroller for displaying the measured height value; thereby, The invention not only makes the overall structure and composition more convenient and convenient, but also reduces the manufacturing cost thereof, and is simpler and more convenient in operation and use, can more accurately measure the height value, and can be increased in its overall implementation. Practical convenience.
