Embodiment 1

[0043] see figure 1 , is a flow chart of the rainwater detection method provided in the first embodiment of the present invention, the detection method is applied to a robot, and includes steps:

[0044] Step S10, acquiring the sound signal of the external environment, and converting the sound signal into a voltage signal;

[0045] Wherein, since raindrops falling on the robot will generate vibration and sound, this embodiment judges whether there is rain in the environment where the robot is located through the analysis based on the sound; For signal acquisition, this embodiment uses a microphone as an example for illustration. The microphone is set on the robot and is used to acquire sound signals from the environment where the robot is located.

[0046] Preferably, in this step, the design of converting the sound signal into a voltage signal effectively facilitates subsequent transformation and analysis of the sound signal, so as to determine whether the robot is currently...

Embodiment 2

[0064] see figure 2 , is a flow chart of the rainwater detection method provided by the second embodiment of the present invention. The detection method is applied to a robot, and the robot is provided with a first sensing electrode and a second sensing electrode adjacent to each other and disconnected, including steps:

[0065] Step S11, acquiring the sound signal on the surface of the robot, amplifying and filtering the sound signal, and converting it into a voltage signal;

[0066] Wherein, the sound signal is amplified by using an amplifying circuit, and the sound signal is filtered by using a filter circuit.

[0067] Preferably, in this step, through the design of signal amplification, the subsequent signal processing is effectively facilitated to amplify the transformation of the signal, and through the design of signal filtering, the interference of external noise is effectively prevented, and the signal conversion is improved. accuracy.

[0068] Step S21, forming a ...

Embodiment 3

[0094] see Figure 5 , is a schematic structural diagram of the rain detection device 100 provided in the third embodiment of the present invention, the rain detection device 100 is applied to a robot, and the rain detection device 100 includes: a voltage signal acquisition unit 10, a voltage waveform diagram forming unit 11 and a judgment unit 12, of which:

[0095] A voltage signal acquisition unit 10, configured to acquire an external environment sound signal, and convert the sound signal into a voltage signal;

[0096] A voltage waveform diagram forming unit 11, configured to form a voltage waveform diagram according to the voltage signal;

[0097] The judging unit 12 is used to judge whether the voltage signal of the voltage waveform diagram exceeds a preset threshold and maintains a preset time, if so, send a rain signal to the robot, and if not, do not send a rain signal to the robot.

[0098] Further, the robot is provided with a first sensing electrode and a second ...

Abstract

The invention is suitable for the technical field of robots, and provides a rainwater detection method, device and system and a robot, and the method comprises the steps: obtaining a sound signal of an external environment, and converting the sound signal into a voltage signal; forming a voltage oscillogram according to the voltage signal; and judging whether the voltage signal of the voltage oscillogram exceeds a preset threshold value or not and maintaining the voltage signal for preset time, if yes, sending a rain signal to the robot, and if not, not sending the rain signal to the robot. According to the invention, the collected sound signal is converted into the voltage signal, whether it rains at present is judged by analyzing the voltage oscillogram, and whether it rains at present is judged by analyzing the sound that rainwater drips on the robot, so that the phenomenon of low detection accuracy caused by judging whether it rains or not only by adopting an analysis resistor is prevented.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a rainwater detection method, device, system and robot. Background technique [0002] Robot is a common name for automatic control machines. Automatic control machines include all machines that simulate human behavior or thoughts and simulate other creatures (such as robot dogs, robot cats, etc.). There are many classifications and controversies about the definition of robots in a narrow sense. Some computers The program is even called a robot. In contemporary industry, a robot refers to a man-made machine device that can automatically perform tasks to replace or assist human work. The ideal high-simulation robot is an advanced integration of cybernetics, mechatronics, computers and artificial intelligence. The product of intelligence, materials science and bionics, the United Nations Organization for Standardization adopted the definition of a robot from the American ...
