The equipment room identification system is based on the maintenance and management of the equipment. In the promotion of the current subway equipment room identification system, RCM is used to serve the purpose of subway operation, strengthen equipment management, improve equipment maintenance environment, and improve equipment maintenance efficiency. On the one hand, it meets the basic needs of the use and maintenance of equipment, attaches importance to the emotional exchange between maintenance and management personnel and equipment, and enhances the spiritual quality of maintenance and management personnel; on the other hand, it pays attention to the changing laws of equipment technology status, and attaches importance to the "six sources of equipment". Management (source of pollution, source of cleaning difficulties, source of failure, source of waste, source of defects, source of accident hazard), and enhance the format of the technical quality paper of the equipment itself.
1 Advanced equipment maintenance and management concept
1.1 Full production maintenance TPM
TPM, also known as full-man production and maintenance RCM, is based on the comprehensive benefits of equipment, with equipment time, space and system as the carrier, and full participation in the equipment maintenance and maintenance system. It requires all departments such as planning, use, and maintenance of the equipment to participate, and all employees from the top management of the company to the front line participate. Compared with the original production maintenance, it mainly highlights a "full" word, that is, full efficiency, system-wide and full participation.
1.2 Reliability Repair RCM
Reliability-centered maintenance (RCM) is a process or method for determining the preventive maintenance requirements of equipment in accordance with the principle of maintaining the inherent reliability and safety of equipment with minimal resource consumption. Yes: Perform system function and fault analysis to clarify the consequences of each fault in the system; use standardized logical decision method to determine the preventive countermeasures for each fault consequence; through on-site fault data statistics, expert evaluation, quantitative modeling, etc. Under the premise of ensuring safety and integrity, the format of the maintenance strategy paper of the system is optimized with the goal of minimum maintenance loss.
2 Application of maintenance concept in equipment room identification system
2.1 Visualization and localization of equipment site management
On-site management is the foundation of enterprise management. All quality, cost, equipment, safety, and environmental management will ultimately be implemented on the “siteâ€. On-site management is to implement the management "visualization" of the overall situation of the operation and the work RCM of each person, so that the management and decision-making departments of the enterprise can see and see at a glance, so that the operation can be adjusted and can be confirmed and confirmed at any time to ensure the enterprise. The overall goal of production and operation can be successfully completed on time, by quality and by quantity.
Figure 1 Fixing and visualization in the equipment room identification system
In combination with the TnPM/TPM equipment on-site management visualization and positioning concept, RCM, based on the principle of “all for service operationâ€, determined the important position of equipment maintenance visualization at the beginning of the marking system planning.
In the visualization and fixed management of the subway equipment room identification system, five principles should be observed: (1) unification: standardization and standardization; (2) simplicity: concise, easy to understand, and binding; (3) distinct: consistent color, clear meaning, clear at a glance (4) Practicality: less money, more work, practicality, and service to the subway; (5) serious: full participation, clear-cut, common compliance, mistakes must be changed, and the format of the dissident thesis is the same.
2.2 Equipment Maintenance Reliability
At the beginning of the design, the equipment room identification system fully considers the maintenance requirements of the equipment. Combined with the RCM theory RCM, the steps for developing maintenance management are shown in Figure 2.
Figure 2 Maintenance management steps based on equipment maintenance reliability
Equipment maintenance management is a process of continuous optimization. As shown in Figure 3, it is necessary to continuously analyze and study the main factors affecting equipment failures based on historical data of equipment maintenance, and continuously adjust and optimize equipment maintenance strategies to better control production equipment. Carry out maintenance and management, reduce RCM of equipment failure, ensure smooth production, and improve overall production efficiency.

3 Conclusion
The equipment room identification system is based on the principle of “serving for operationâ€. It integrates advanced equipment maintenance and management concepts to provide a harmonious human-computer interaction environment and provides information for designers, builders, users and maintainers. A comprehensive solution that addresses the functions of messaging, identification, communication and updates. Its implementation and promotion will be beneficial to the maintenance and maintenance of subway equipment, which will help improve the maintenance environment of equipment rooms and improve the maintenance efficiency of employees.
