Embodiment Construction

[0021] Such as figure 1 As shown, a high-precision fall real-time judgment system includes a drop sensor set on the robot, and also includes a microprocessor, an adaptive filter, an acquisition module and a bus;

[0022] The drop sensor is used to collect the original drop signal of the robot; the drop sensor uses the ST1612D2 model, which is improved when the original ordinary sensor has a low range and weak signal, so that the maximum measurement range is 0-3m, and the response time is short, and the volume Small, easy to integrate and install;

[0023] The acquisition module is used to receive the original drop signal and generate the original drop data; the acquisition module includes a signal amplifier and an analog-to-digital converter, the signal amplifier is used to amplify the original drop signal, and the analog-to-digital converter is used to convert the original drop signal of the analog quantity into Digital raw drop data;

[0024] The microprocessor receives th...

Abstract

The invention provides a high-precision drop real-time judgment system, which comprises a drop sensor arranged on a robot, a microprocessor, an adaptive filter, an acquisition module and a bus, the drop sensor is used for collecting an original drop signal of the robot; the acquisition module is used for receiving the original drop signal and generating original drop data; the microprocessor receives original drop data through a serial port; an embedded operating system is arranged in the microprocessor; the self-adaptive filter acquires original drop data through a serial port and filters white noise in the original drop data so as to generate filtered drop data; the microprocessor receives the filtering drop data through a serial port and outputs the filtering drop data to a decision endof the robot through a bus; the system is developed on the basis of a microprocessor platform, an original embedded operating system is improved, the processing performance and time consumption of athread pool are optimized, low power consumption and high real-time performance can be achieved, adaptive filtering denoising is conducted on a data layer, and the precision is high.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a high-precision fall-time judgment system. Background technique [0002] The use of robots in the context of artificial intelligence big technology. It is widely used in various industries and scenes in life, and the existing scenes have a certain complexity, which requires the robot itself to be able to adapt to move in various scenes. At this stage, effective distance measurement or infrared sensors to determine the falling distance have certain limitations: 1. The misjudgment rate is as high as 30%. 2. The existing sensor systems mostly use the cycle detection mode, which has a large delay It cannot be real-time, which is not conducive to the judgment of the robot's motion state. [0003] In order to solve the above problems, the present application proposes a high-precision real-time judgment system for falling. Contents of the invention [0004] The purpose ...
