Intelligent industrial safety lock

Abstract

The invention relates to an intelligent industrial safety lock which comprises a controller, a locking actuator and a personal IC card. The controller is used for completing the functions of identifying an operator, checking entering and withdrawing personnel information and performing unlocking; the locking actuator is used for completing locking and unlocking functions and a self-checking function of automatic equipment; company identifier information, employee ID codes, employee authority information and IC card special encrypted data information are stored in the personal IC card; and thecontroller is connected with the locking actuator through a communication bus. The beneficial effects of the intelligent industrial safety lock are that the system can effectively prevent a person whodoes not have related safety knowledge and operation skills from entering privately; other irrelevant personnel or other accidents can be prevented from closing the safety door, and the automatic equipment is reset to operate; the self-checking function is achieved, and safety accidents caused by failure of the safety lock function can be prevented; an operator can be reminded to standardize operation, and some accidental unsafe factors are effectively avoided.

Description

technical field [0001] The invention belongs to the field of automation control, and relates to the safety control technology of the safety door of the automatic production line, in particular to an intelligent industrial safety lock. Background technique [0002] Industrial automation lines are generally installed with an overall closed safety fence, which is used to isolate the automation area into an independent area, preventing people and other movable equipment from entering the automation operation area and causing personal injury or equipment damage accidents. The safety fence is equipped with a safety door for maintenance personnel to enter and exit. A safety lock interlocked with the automation equipment is installed on the safety door. When the safety door is in the open state, the power supply of the automation equipment is cut off, and the automation equipment in the area stops running, ensuring that the maintenance personnel entering the automation operation area...

AI Technical Summary

Problems solved by technology

This technology only solves the risk of personal injury to operators in the area caused by accidental door closing and recovery of automation equipment in the area when individual maintenance personnel or multiple maintenance personnel enter the automated operation area;

[0006] This technology mainly has the following unsafe loopholes: 1. During maintenance, the door must be open, and other casual personnel can directly enter and cause injury accidents; suppose three people, A, B, and C, enter the automation area for maintenance, and at this time the safety door is open, and the new Ding, who has entered the job and has not received safety training, passes by and finds that the safety door is open. Out of curiosity, he enters the automation area alone to look around. The three persons A, B, and C complete the maintenance task, but Ding is not found. He walks out of the automation area and resets the safety door lock. The automation equipment in the area Start to run, it will cause injury accident

2. The artificial safety device needs to be purchased and installed separately in the application, which is inconvenient to use

[0007] The existing safety door locks basically belong to mechanical switches or photoelectric switches, the functions are too simple, there is no monitoring of the working status of the production line equipment, and no closed-loop control is formed, so safety accidents caused by the failure of safety locks often occur
