AI Technical Summary

Technical Problem

Existing methods for implementing safety functions in lasers suffer from low safety or increased cost and size. In particular, the single-breakpoint control method has low safety, while the dual-channel control method based on safety relays increases device cost and size.

Method used

A laser safety detection method employing dual control modules and dual detection channels is used. The first and second control modules detect changes in the power-on signal to determine if they are the same. When a power-off signal is detected, a power-off command is sent to the constant power supply to shut down the laser pump source and prevent laser output.

Benefits of technology

It improves the safety performance of the laser, reduces costs and shrinks the size of the equipment, while ensuring safety even if any control module fails, making it suitable for miniaturized equipment design.

Abstract

The application relates to the field of laser equipment, and discloses a laser safety detection method and device, computer equipment and a storage medium, the method comprising the following steps: when a first control module detects a first power-on change signal of a first laser safety detection channel, acquiring a second power-on signal of a second laser safety detection channel through a second control module; judging whether the first power-on change signal is same as the second power-on signal; if the first power-on change signal is same as the second power-on signal, and the first power-on change signal is a power-off signal, sending a power-off instruction to a constant power supply, so that the constant power supply stops supplying power to a laser pump source according to the power-off instruction, and the first control module is electrically connected with the constant power supply. The application can improve the safety performance of the laser under the premise of not significantly increasing the production cost and the equipment size.
