[0053] Lead hammer mechanism 11 and the light emitter 101 are interconnected and lead hammer mechanism 11 always point in the center of the earth gravity direction, a lead hammer mechanism 11 is provided for correcting the light emitter 101 is horizontal.
[0054] It should be noted that the apparatus 100 can be measured by measuring the high angle information and distance information, calculates the height of the object, from which any terrain conditions, high accuracy, can significantly reduce the labor intensity, at the same time, the device may be provided separately measuring the angle or distance measurement, angle measurement and a distance measuring instrument, the structure design, practical.
[0055] Wherein the hammer mechanism 11 may be a lead plumb mass, and the light emitter 101 which are connected to each other, the angle can be determined at any time between it and the light emitter 101, when the plumb bob 101 block light emitter and perpendicular to each other, may be DESCRIPTION light emitter case 101 and the horizontal plane parallel to the plumb correction means 11 functions as the light emitter 101 is horizontal.
[0056] Alternatively, the light emitter 101 is a laser emitter.
[0057] Specifically, the laser emitter is divided into continuous laser a pulsed laser and a laser working according to the embodiment. Helium-neon, argon ion, krypton gas lasers such as cadmium continuous work output state, a phase laser ranging; gallium arsenide double heterostructure semiconductor laser, an infrared distance; ruby, neodymium glass and other solid-state lasers, for pulsed laser ranging. Since the laser emitter monochromatic laser good, strong directivity and other characteristics, together with an electronic circuit integrated into a semiconductor, in comparison with the EDM, not only can work day and night, and the distance measurement accuracy can be improved.
[0058] In the present embodiment, the laser emitter includes a laser emitting tube 1011 and a power supply module 1012, the power supply module 1012 is provided for the power supply to the laser emitting tube 1011.
[0059] It should be noted that the power supply module 1012 emits a laser tube 1011 to provide power, thereby facilitating lasing, so that the device can be independently used in outdoor environments, improve the degree of adaptation to the environment measurement, no additional power supply carrying means, improve the efficiency measurement.
[0060] Refer again figure 1 , Measuring apparatus 100 further includes a high display means 12, display means 12 and 10 electrically connected altimeter means, and display means 12 is provided for displaying the angle information, the distance information and the object height.
[0061] It will be appreciated that the display means 12 can display various data in real time, to obtain individual distance and angle measuring functions at the same time, facilitates the user to read data, more convenient control information based trees.
[0062] Alternatively, the display means 12 is a liquid crystal display or liquid crystal flat screen surface or a curved surface OLED display.
[0063] Specifically, the LCD English full name is abbreviated as LCD Liquid Crystal Display, it is a kind of display. Screens used in televisions and computer displays. The advantage of this display is low power consumption, small size, low radiation. LCD using a liquid crystal solution of two polarized material, current will achieve the purpose of rearranging the crystal when imaged through the liquid. Here a liquid crystal display or liquid crystal flat screen surface with low power consumption characteristics, advantageous for use in the field for a long time, so that a single user can be measured more trees when they go out, thereby improving measurement efficiency. I.e. the OLED organic light emitting diode display surface. OLED display technology with traditional LCD display in different ways, no backlight, the very thin coating of organic materials and glass substrates (or flexible organic substrate), when a current is passed, these organic materials will be light. So that the OLED display can be made lighter and thinner, larger viewing angle, and can significantly save power consumption. OLED and LCD display principle has essential difference is mainly driven by an electric field, and an organic semiconductor material over the light-emitting light-emitting material by the injection and recombination of carriers. In essence, is a transparent electrode of ITO glass as an anode device, a metal electrode as a cathode, by a power-driven, electrons from the cathode to the electron transport layer, hole injection from the anode into the hole-transporting layer, then migrate to the light emitting points layer, after both met generating excitons, so excited luminescent molecules, after radiation source. In simple terms, an OLED screen, that is, by the millions of "little light bulbs", whose capacity can reduce power consumption more, but at a higher cost. In this embodiment do not limit the display means 12, merely illustrative thereof, other embodiments in the present embodiment, the display means 12 may also be other structures.
[0064] In the present embodiment, the measuring apparatus 100 further includes a high voice reminder means 13, means 13 are voice reminder and angle measurement module 102, and a distance measuring module 103 is electrically connected to a calculation module 104, and the voice reminder means 13 is provided for emitting voice.
[0065] It should be noted that the voice reminder alert mechanism 13 can readily detect the user data, thereby indicating the working state of the device and the detected data to the user.
[0066] Alternatively, the voice reminder buzzer 13 institutions. When the measuring device 100 enters a high measurement mode, the buzzer twice, when the end of the measurement data, short beeps the buzzer sound, then the user can clearly grasp the operational state of the measuring device 100 is high, thereby improving the operation convenience, reduce misuse rate. It will be appreciated that, depending on the specific implementation environment, the voice reminder means 13 may be a speaker, alerting the user that may play a role, at the same time, able to broadcast the measured data, functions to improve ease of operation, to reduce false operating action rates. The present embodiments are merely illustrative voice reminder means 13 does not constitute particularly limited thereto.
