Abstract

The invention relates to the field of control, in particular to a safety control system. The system comprises a safety controller and a joint server, the safety controller comprises a first control panel and a second control panel, the first control panel is in communication connection with the joint server through a first communication network, and the second control panel is in communication connection with the joint server through a second communication network. The communication connection is established between the first control board and the second control board through an intermediate communication channel. The first control panel transmits a safety control instruction to the joint server through the first communication network; and the second control board transmits a safety control instruction to the joint server through the second communication network. When the first communication network breaks down, the first control panel transmits the safety control instruction to the second control panel through the middle communication channel, and the second control panel transmits the safety control instruction to the joint server. The system is used for solving the problem that a single communication channel mode is poor in safety and reliability when safety control is carried out on the joint server.

Description

technical field [0001] The present application relates to the field of control, in particular to a safety control system. Background technique [0002] Generally speaking, a collaborative robot includes at least one joint, and a corresponding joint servo is configured at the joint, and each joint has corresponding limit parameters such as limit, speed limit, and torque limit. When the data of the collaborative robot is abnormal due to failure or other reasons, the corresponding joint servo will automatically decelerate and stop according to the preset safety strategy. [0003] A way to implement a security policy is to set a separate security controller. The safety controller and the joint server are connected through a communication network. As an independent third party, the safety controller performs safety monitoring work in real time. When a problem occurs to the servo robot, it can issue a deceleration command and a pause command. [0004] However, the safety control...
