Abstract

The utility model discloses an ultrasonic distance measurer which comprises a shell, and an ultrasonic probe, a central processing unit (CPU), a liquid crystal display, a battery and an on-off key are arranged in the shell, wherein the ultrasonic probe, the central processing unit, the liquid crystal display (LCD), the battery and the on-off key are electrically connected; the ultrasonic probe is used for emitting and receiving ultrasonic waves, and a measured distance is calculated by the CPU according to return time and displayed on the LCD; the shell is internally provided with a loudspeaker; and the CPU is provided with a voice generation circuit used for reading a measured value through the loudspeaker. In the utility model, the measured value can be read through the loudspeaker by adding the voice generation circuit in the ultrasonic distance measurer, so that the measured result can be mastered under the condition of poor light, thus the ultrasonic distance measurer is convenient to use.

Description

A kind of ultrasonic range finder

Technical field

The utility model relates to a kind of ultrasonic range finder.

Background technology

Ultrasonic range finder is being used widely as a lot of fields such as engineering, traffic at present, ultrasonic probe emission and the reception ultrasound wave of ultrasonic range finder by being provided with in it, the distance that goes out to record according to the Time Calculation that reflects by central processing unit again, but generally all be to be presented on the LCDs, under the environment of dark, be difficult to see clearly numerical value, use and cause certain difficulty.

Summary of the invention

Problem to be solved in the utility model provides a kind of ultrasonic range finder with vocal function.

The technical scheme that the utility model adopted is: ultrasonic range finder, comprise shell, be provided with ultrasonic probe, central processing unit, LCDs, battery and on ﹠ off switch in the shell, ultrasonic probe, central processing unit, LCDs, battery and on ﹠ off switch are electrically connected, ultrasonic probe emission and reception ultrasound wave, the distance that goes out to record according to the Time Calculation that reflects by central processing unit and be shown in LCDs again, be provided with loudspeaker in the described shell, described central processing unit is provided with the speech utterance circuit in order to read measured value by loudspeaker.

In order accurately to locate position to be measured, be provided with a laser pen in the described shell with thinking the ultrasonic probe location, described laser pen comprises laser head and driving circuit, and laser head and ultrasonic probe are close to and are be arranged in parallel, by the accurate indication position to be measured of laser head emitted laser bundle.

For the measured value under the different temperatures is more accurate, be provided with a temperature sensor in the described shell, described central processing unit is provided with temperature-compensation circuit in order to according to the temperature sensor measured value measurement result is compensated.

The beneficial effects of the utility model are: the utility model can be read measured value by loudspeaker by increasing the speech utterance circuit in ultrasonic range finder, making, is convenient in time know measurement result under the light condition of poor, uses more convenient.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

Fig. 1 is the outside drawing of the utility model embodiment;

Fig. 2 is the inside decomposition texture synoptic diagram of the utility model embodiment.

Embodiment

As Fig. 1, shown in Figure 2, ultrasonic range finder comprises shell 1, be provided with ultrasonic probe 2 in the shell 1, central processing unit 3, LCDs 4, battery 5, loudspeaker 6, temperature sensor 7, start key 8 and measurement key 9, ultrasonic probe 2, central processing unit 3, LCDs 4, battery 5, loudspeaker 6, temperature sensor 7, start key 8 and measurement key 9 are electrically connected, also be provided with a laser pen in the shell 1, laser pen comprises laser head 10 and driving circuit 11, laser head 10 is close to ultrasonic probe 2 and is be arranged in parallel, laser head 10, driving circuit 11, laser head start key 12 is connected separately with battery 5, not only can indicate position to be measured after opening laser pen by laser head 10 emitted laser bundles, also can use as laser pen separately, after pressing start key 8 and opening laser head start key 12, mobile laser beam is to position to be measured, press again and measure key 9, ultrasonic probe 2 emission ultrasound waves are to laser head 10 indicating positions, and the ultrasound wave of reception reflected back, go out to record distance and be shown in LCDs 4 by the Time Calculation of central processing unit 3 again according to reflected back, the speech utterance circuit is read measured value by sound horn simultaneously, 7 of temperature sensors will record the ambient temperature transmission and return central processing unit, calculate compensation measurement by central processing unit according to the relation of temperature and ultrasonic propagation velocity.
