The system adopts non - porous passive dynamic intelligent lock combined with temperature , humidity , water level , oxygen content and various gas detection sensors , according to the task work order , the management rules of dynamic authorization and logical operation are adopted to avoid on - site unauthorized operations and unsafe operations , and establish a zero - trust management mechanism for the safety production management of the industry .

 Application effect :

1, improve the intrinsic security : through the application of passive non - porous dynamic intelligent lock , more effective lock - in management of limited space places , to eliminate the limited space places open at will , unauthorized work , overtime work , delay work and other limited space management problems .

2, reduce safety accidents : the use of " technical defense + civil air defense + physical defense " control ideas , effectively prevent workers from unsafe behavior caused by safety accidents , through the logic function of the detection device and smart lock , to achieve excessive security factors in the space of the intelligent lock logic lock , forcing employees to perform " ventilation first , after detection , then work " safe operation behavior , ensure work The safety of the human artificial body .

3. Optimize management , improve quality and efficiency Through the statistical analysis of working behavior , working habits , working frequency , working efficiency and equipment operation and maintenance , establish a limited space management ledger to assist management decision - making , and build a limited space operation management system with approval in advance , tracking in the matter and traceability after the event .
