Since March 1, the group's OA security management information system has been officially put into operation. The system includes three parts: project management system, security inspection system and equipment dynamic management system. The system is designed for the fact that the company has many projects and wide geographical distribution, and the safety management is difficult to achieve full coverage. The system can provide real-time project information, in-use large-scale machinery and equipment information, project safety routine inspection information, and provide solid data support for the group company to implement efficient management, scientific decision-making, supervision and inspection of the project. The formal operation of the OA safety management information system marks that the safety management of the group company has stepped up to a new level. (security equipment)
