Embodiment 1

[0026] refer to figure 1 As shown, the distance measuring device in this embodiment includes an ultrasonic transceiver module 3, a temperature sampling module 6, a humidity sampling module 7 and a processor 1. The ultrasonic transceiver module is used to transmit ultrasonic waves in a preset direction and receive echoes. The temperature sampling module 6 is used to measure the ambient temperature, and the humidity sampling module 7 is used to measure the ambient humidity. It should be understood that figure 1 The alarm module 8, the brake switch 9 and the 485 communication module 10 are not located in the distance measuring device. The single-chip microcomputer 1 includes a ranging module and a correction module, and the correction module is used to correct the standard sound velocity to the actual sound velocity according to the preset correction formula, the ambient temperature and the ambient humidity, and the distance measuring module is used to obtain the sound velocity ...

Embodiment 2

[0034] refer to figure 1 As shown, the robot system of this embodiment includes the ranging device of Embodiment 1, an alarm module 8 , a brake switch 9 and a 485 communication module 10 .

[0035] The alarm module 8 is used for receiving the obstacle distance measured by the ranging module, and sending an alarm when the received obstacle distance is smaller than a preset first distance threshold. The brake switch 9 is used to send an alarm when the obstacle distance is smaller than a preset second distance threshold, and the second distance threshold is smaller than the first distance threshold. The 485 communication module 10 is used to send the obstacle distance measured by the ranging module to a remote terminal in real time.

[0036]When the distance between the robot system and the obstacle is close to the safe value, the single chip computer outputs the level control alarm module 8 for early warning. When the safety value is exceeded, the single-chip microcomputer wil...

Abstract

The invention discloses a distance measuring device and a robot system. The distance measuring device comprises ultrasonic transceiver modules, a temperature sampling module, a moisture sampling module and a processor, wherein the ultrasonic transceiver modules are used for sending ultrasonic waves to a preset direction and receiving back waves; the temperature sampling module and the moisture sampling module are used for measuring and obtaining the temperature and the moisture of the environment; the processor comprises a distance measurement module and a correction module; the correction module is used for correcting the standard sound velocity into the actual sound velocity according to the preset correction formula, the environment temperature and the environment moisture; the distance measurement module is used for acquiring the time interval between the sending of the ultrasonic waves by the ultrasonic transceiver modules and the receiving of the back waves by the ultrasonic transceiver modules, and calculating the distance to an obstacle. According to the distance measuring device and the robot system, provided by the invention, the accuracy of the distance measurement is not affected by environmental factors at all; particularly, in the circumstances of relatively large temperature and moisture changes, accurate distance measuring capability can still be provided; the robot system can give effective alarming, so as to avoid damages caused by crashing the obstacle.

Description

technical field [0001] The invention relates to a distance measuring device and a robot system. Background technique [0002] In modern industry, ranging is a basic technology. Compared with visible carriers such as rulers, wireless ranging is more accurate and convenient, so it has been widely used. Commonly used wireless ranging methods include laser, ultrasonic, radio, and eddy current. Among them, ultrasonic ranging is not affected by external light and magnetic fields, and can be used in harsh environments, so it is very popular. However, in the process of ultrasonic propagation, temperature and humidity have a great influence on the speed of sound, which makes the accuracy of ultrasonic measurement greatly affected by environmental factors, and cannot be well applied to various environments, especially difficult to apply to underwater environments. . Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the la...
