Embodiment Construction

[0044] The present invention will be described in detail in conjunction with accompanying drawing now. This figure is a simplified schematic diagram only illustrating the basic structure of the present invention in a schematic manner, so it only shows the components relevant to the present invention.

[0045]In this embodiment, there is one robot 2 in the working area as an example for illustration. When there are multiple robots 2, the shooting range of the camera 6 may be larger.

[0046] Such as figure 1 As shown, a human-machine safety protection system of the present invention includes a robot 2, a camera 6 and a computer 4. In order to facilitate subsequent data processing, the camera 6 is installed directly above the robot 2, and the robot 2 and the camera 6 are both Connected with the computer 4, the robot 2 has at least one movable execution part; the camera 6 is used to take images within the detection range of the surrounding environment of the robot 2, and send th...

Abstract

The invention provides a man-machine safety protection system and a safety protection method. A common camera is adopted and arranged at the top end of a robot, whether an object enters the detectionrange specified by a user is judged through a foreground extraction method by filtering out pixels of a robot body, if a moving object appears, the robot is slowed down or stopped, and safety of the robot and operators is ensured. The common RGB camera is adopted, and the cost is low; and the camera does not need to be calibrated, the detection range can be specified according to the user requirements, maintenance is convenient, configuration is flexible, and efficiency is high.

Description

technical field [0001] The invention relates to the technical field of man-machine safety protection, in particular to a man-machine safety protection system and a safety protection method. Background technique [0002] Traditional industrial robot production operations usually set up isolation fences around them or use peripheral sensors to isolate robots from humans. Traditional sensors such as pressure-sensitive sensors or scanning laser rangefinders are expensive and troublesome to maintain. They need to be reinstalled and debugged when the on-site environment changes, and the efficiency is low; more advanced tactile and force sensors are also quite expensive. The contact sensor is based on the premise of the force-generating contact between the human and the robot. If the robot runs too fast or the execution end is sharp, the robot still has a certain degree of danger. [0003] Vision sensors provide richer information than force sensors and other traditional sensors. ...
