Abstract

The invention relates to a detection method and device of a safety controller, equipment and a storage medium. The method comprises the steps: acquiring at least two blocks obtained by dividing the space of a storage unit in advance; determining a current to-be-detected target block from at least two blocks; judging whether a control task for the equipment is acquired or not; if the control task is obtained, enabling a control device to execute the a control operation corresponding to the control task, and after the control task is executed, detecting the target block. The storage unit is detected for multiple times through the block division operation, whether the control task exists or not is determined before the target block is detected each time, and when the control task exists, detection on the target block is interrupted, and the control device executes the control operation corresponding to the control task, so the situation when the storage unit is detected at a time, due to the fact that a control task on the equipment is not executed, the potential safety hazards exist in the operation of the equipment.

Description

technical field [0001] The present application relates to the field of industrial robots, and in particular to a detection method, device, equipment and storage medium of a safety controller. Background technique [0002] With the continuous development of robot technology, robots are widely used in various aspects such as welding, assembly and handling in the industrial field. A robot is an intelligent machine that can work autonomously. When working, it can communicate with a safety controller, receive control instructions from the safety controller, and perform corresponding actions in response to the control instructions. [0003] In order to ensure the safe control of the robot, it is necessary to self-check the MCU (MicrocontrollerUnit, micro control unit) in the safety controller. In the related art, when the safety controller implements the MCU self-test, the thread of the safety controller completes all storage such as FLASH (non-volatile storage unit) and RAM (Ran...
