Embodiment 1

[0024] Such as figure 1 As shown, the embodiment of the present application provides a method for improving the safety of the motion speed of an industrial robot. The method is applied to a robot somatosensory teaching system, and the robot somatosensory teaching system is connected to an inertial sensor in communication. The method includes :

[0025] Step S100: Build a first peripheral circuit, wherein the first peripheral circuit is used to control the use of the first inertial sensor;

[0026] Specifically, the construction of the first peripheral circuit is the key factor for the superior performance of the sensor. Since the output terminals of the sensor are very small signals, if the useful signal is interfered due to the influence of noise, it will affect the subsequent The accuracy of signal processing, so it is particularly important to strengthen the anti-interference design of the sensor circuit. Among them, the noise of the sensor circuit mainly includes low-freq...

Embodiment 2

[0078] Based on the same inventive idea as a method for improving the safety of the motion speed of an industrial robot in the foregoing embodiments, the present invention also provides a system for improving the safety of the motion speed of an industrial robot, such as figure 2 As shown, the system includes:

[0079] A first building unit 11, the first building unit 11 is used to build a first peripheral circuit, wherein the first peripheral circuit is used to control the use of the first inertial sensor;

[0080] The second building unit 12, the second building unit 12 is used to build the first main control circuit, wherein the first main control circuit is used to control the use of the robot somatosensory teaching system;

[0081] A first generating unit 13, the first generating unit 13 is configured to collect the first user's somatosensory action according to the first inertial sensor, and generate a first original signal;

[0082] A first obtaining unit 14, the firs...

Abstract

The invention discloses a method and system for improving the safety of the motion speed of an industrial robot. The method is applied to a robot somatosensory teaching system, and the robot somatosensory teaching system is communicated with an inertial sensor. The method includes: building a first A peripheral circuit and a first main control circuit; collect the first user's somatosensory action according to the first inertial sensor, and generate a first original signal; obtain a first effective sampling frequency; performing signal acquisition on an original signal to generate a first time-domain waveform to complete spectrum analysis, and then obtaining first spectrum analysis data; performing digital filtering on the first spectrum analysis data to extract a first effective signal. It solves the technical problem in the prior art that the data collected by the sensor contains a lot of noise and is easily affected by external factors, which will interfere with the movement of the robot and even cause unsafe factors.

Description

technical field [0001] The invention relates to the related field of industrial robots, in particular to a method and system for improving the safety of the motion speed of an industrial robot. Background technique [0002] As an important part of "machine replacement", industrial robots have gradually received more and more attention from domestic manufacturers in recent years. The teaching pendant is the core component of the control system of the industrial robot, and it is the interface for human-robot interaction. It is mainly used to complete the pose teaching of the robot, robot parameter setting, program editing and the generation, reading and saving of teaching files. In order to achieve rich graphic information display and parameter editing functions, the existing teaching pendant is equipped with a large LCD screen and complicated buttons. The operation is complicated, the teaching efficiency is low, and professional robot technology is required. Personnel can op...
