Embodiment 1

[0022] The multifunctional height measuring ruler includes a ruler body 3, scales are drawn on the side and bottom of the ruler body, a battery 1 and a circuit board 2 are installed in the ruler body, a processor, an angle sensor, a voice playback module and a wireless communication module are installed on the circuit board, and the voice playback module outputs Connect the loudspeaker 8, the loudspeaker is installed in the ruler, and the shell is perforated to facilitate sound transmission. The first horizontal air bubble tube 4 is installed in the horizontal direction of the middle part of the scale body, and the second horizontal bubble tube 5 is installed in the vertical direction of the scale body. The scale body is installed display 6 near one end side. Measuring switch 7 is installed near the hand-held position at one end of the scale body. One end of the bottom surface of the ruler body is perforated, and the ranging sensor 9 is installed, and the ranging sensor is fl...

Embodiment 2

[0024] The scale body 3 can be made into a retractable or foldable type, which is more convenient to carry. The handheld end of the ruler body can be made into a shape that is convenient for holding by hand.

Embodiment 3

[0026] The distance measuring sensor 9 can be an independent probe for transmitting and receiving, such as some ultrasonic distance measuring sensors, so two holes should be opened on the bottom surface of the scale body. A laser can also be added next to the ranging sensor to assist in alignment during measurement.

Abstract

The invention discloses a multifunctional body height measuring ruler, wherein a distance measuring sensor, a horizontal bubbler tube, a display, a loudspeaker, a switch, a battery and a circuit board are arranged in a ruler body; and a processor, an angle sensor, a voice playing module and a wireless communication module are arranged on the circuit board. The measuring ruler can be leveled by a user under the assistance of the horizontal bubbler tube and the angle sensor; and accurate body height measurement can be achieved by virtue of a method of directly measuring a distance from the head top of a detected object to the ground through the distance measuring sensor which is arranged in the ruler body. The body height measuring ruler disclosed by the invention can measure the heights of persons in standing and lying postures, and the body height measuring ruler has a voice playing function, so that people with visual impairment can use the body height measuring ruler conveniently. The body height measuring ruler disclosed by the invention has a function of measured data wireless transmission and functions of a level ruler.

Description

technical field [0001] The invention relates to a length measuring tool, which belongs to a height measuring ruler. Background technique [0002] The current mainstream height measuring instrument usually consists of a base, a telescoping rod and a swimming cross bar. This measuring instrument is relatively cumbersome to operate, and has a large volume and is inconvenient to move. [0003] The ultrasonic height measuring ruler that has appeared in recent years, such as the Chinese utility model patent with the notification number CN204192620U, discloses an "ultrasonic height measuring ruler", which measures the angle through ultrasonic distance measurement and horizontal sensor, and measures it by means of processor calculation. Height, with the characteristics of portability. However, due to the complexity of this measurement method, the error of the ultrasonic distance measurement and the error of the level sensor will be superimposed, and the calculation error of the pro...
