Problems solved by technology

Using this method for distance measurement can significantly increase the measurement distance, but it is necessary to make two machines, one for transmitting and the other for receiving processing, and at the same time, other auxiliary devices must be used to ensure the synchronization of sending and receiving. The production cost is high and the operation is extremely inconvenient

Embodiment 1

[0017] Embodiment 1, as shown in Figure 1: ultrasonic distance measuring device, comprises ultrasonic transceiver head, ultrasonic transceiver circuit, laser emitter, laser indication positioning circuit, temperature compensation circuit, buzzer, buzzer signal processing circuit, display, display circuit, function operation keys, power supply and microprocessor; two ultrasonic transceiver heads arranged opposite to each other are connected to the microprocessor through the ultrasonic transceiver circuit; , so as to indicate and locate the measurement of each ultrasonic wave; the temperature compensation circuit is connected to the microprocessor, and the microprocessor senses the ambient temperature through the temperature compensation circuit, so that the calculated distance can be obtained according to different sound wave propagation speeds. Compensation; the buzzer is connected to the microprocessor through the buzzer signal processing circuit, so that when the distance is ...

Embodiment 2

[0019] Embodiment 2, as shown in Figure 2: includes three ultrasonic transceivers and three laser emitters, the three ultrasonic transceivers are connected to the microprocessor via an ultrasonic transceiver circuit; wherein two ultrasonic transceivers are arranged facing each other. The three laser emitters are connected to the microprocessor through their own laser indicating and positioning circuits, so as to indicate and locate each ultrasonic measurement. Others are with embodiment 1.

[0020] The device can have three distance measurement modes, besides the one-way and two-way distance measurement in Embodiment 1, it can also perform distance measurement in three directions at the same time. The function operation keys are provided with gears for switching various distance measuring modes, and are realized by a microprocessor.

[0021] The signal processing of the present invention takes the microprocessor as the control subject, sends out various control signals by it,...

Abstract

A method for increasing measurement distance of ultrasonic wave includes using two paths or above of ultrasonic waves to measure distance values of two or above directions through microprocessor and relevant channel and enabling to directly measure out distance sum of two and the same directions for making once measurement distance value be above 30m so as to increase measurement distance of ultrasonic wave under condition that performance of ultrasonic wave transceiver head is not changed.

Description

Technical field [0001] The invention relates to a method and a device for measuring distance by using ultrasonic waves. Background technique [0002] Ultrasonic distance measurement is a commonly used non-contact distance measurement method. At present, ultrasonic ranging methods are mainly divided into two categories: the first method adopts the reflective measurement method of transmitting and receiving, using a single ultrasonic head to send ultrasonic waves in the direction to be measured, and then the same ultrasonic head or another ultrasonic head on the same device. The signal is received to complete the distance measurement; using this method for distance measurement, the measurement distance is limited, generally not more than 20 meters, and the range of use is limited to a certain extent. The second type of ultrasonic distance measuring method is to use a split device, which is divided into two parts: the host and the target. Before the measurement, the target is ...
