Embodiment Construction

[0042] Such as figure 1As shown, the safety logic control system provided by this embodiment includes a servo drive module 1, a safety unit 2, and a bus transmission master station 3 connected to each other. The safety unit 2 and the bus transmission master station 3 monitor each other, and the safety unit 2 and the servo A first safety loop 10 is established between the drive modules 1 , and a second safety loop 20 is established between the bus transmission master station 3 and the servo drive module 1 . When the safety unit 2 receives an abnormal input signal, detects that the bus transmission master station 3 fails or itself fails, the first safety loop 10 generates a first safety control signal K1 to turn off the output of the servo drive module. At the same time, when the bus transmission master station 3 receives the abnormal input signal output by the safety unit 2, or when it fails or detects that the safety unit 2 fails, a second safety control signal K2 is generated...

Abstract

The invention provides a robot safety logic control system, which includes a servo drive module, a safety unit, and a bus transmission master station connected to each other. The safety unit and the bus transmission master station monitor each other, and the safety unit and the servo drive module establish a A safety loop, a second safety loop is established between the bus transmission master station and the servo drive module. When the safety unit receives an abnormal input signal, monitors that the bus transmission master station fails or itself fails, a first safety control signal is generated in the first safety loop to close the output of the servo drive module; at the same time, when the bus transmission master station receives The second safety control signal is generated in the second safety loop to close the output of the servo drive module when the abnormal input signal to the output of the safety unit, its own failure, or the failure of the safety unit is detected.

Description

technical field [0001] The invention relates to the field of robot control, and in particular to a robot safety logic control system. Background technique [0002] With the continuous advancement of industrial automation, most production lines are automated, and various types of industrial robots are applied to different product production lines to apply to different application scenarios, thus saving a lot of manpower and financial resources and greatly improving work efficiency. . [0003] For industrial robots, safety comes first. In the existing industrial robot control system, the safety logic is mainly realized by the independent module (i.e. safety unit) in the robot control cabinet; Output the safety signal to close the output of the servo drive module, so as to realize the emergency stop of the robot action to ensure safety. In the existing logic control of this kind, the control of the safety logic is completely performed by the independent module of the safety ...
