Abstract:

There are many problems in tunnel mechanical and electrical equipments, such as multiple types, independent software system, equipment linkage control in emergency disposal by manual operating multisystem and lack of preventive maintenance of equipment. Hence, a comprehensive management and control system for tunnel mechanical and electrical equipment is established based on advanced technologies such as Internet of Things, cloud computing, etc. The main functions of the system include: (1) The mechanical and electrical equipment in tunnel field is divided into PLC control equipment and nonPLC control equipment; different data acquisition methods are adopted for different types of equipment to realize monitoring and fault alarm of mechanical and electrical equipment in tunnel. (2) According to related requirements and considering the location and regional impact of traffic incidents, an emergency plan for linkage control of mechanical and electrical equipment is formulated to realize comprehensive traffic control and traffic guidance in tunnels. (3) The historical maintenance data of mechanical and electrical equipment are collected and the massive historical detection data are cleaned and analyzed based on big data technology provided by cloud platform; the mechanical and electrical equipment with abnormal changes in the detection data should be paid attention to, so as to realize preventive maintenance and differential cleaning maintenance of mechanical and electrical equipment. By adopting the system, the intellectualization and informatization of tunnel operation and maintenance stage can be realized, the economic benefits of operation can be improved, and the level of safe operation and management of tunnel can be improved.
