摘要： The present disclosure provides an industrial robot safety control system, a back-up safety circuit and a safety module. The safety module includes a first safety circuit and a second safety circuit. The first safety circuit and the second safety circuit receive a warning signal at a same time. The first safety circuit is configured to respond to the warning signal. The second safety circuit include a delay system and an event response circuit. The delay system sets a time delay when receiving the warning signal, wherein, when the delay system does not receive a first control signal indicating that the first safety circuit has responded to the warning signal during the time delay, the delay system controls the event response circuit to respond to the warning signal. The present disclosure may help avoid the problem of common mode failure of the back-up safety mechanism.

摘要： The present disclosure provides an operation instruction response control method and terminal for a human-machine interface. An operation instruction is compared with an operation instruction at the tail of an operation instruction queue while the human-machine interface is in a busy state, and stored in the operation instruction queue while the operation instruction is inequivalent to the operation instruction at the tail of the operation instruction queue; the operation instruction is stored in the operation instruction queue directly while the human-machine interface is not in the busy state. The present disclosure is capable of keeping receiving operation instructions while the human-machine interface is busy, and filtering out invalid operation instructions to avoid the backlog, which shortens the delay time of the response to the operation instructions.
