Systems such as the "Sharp Eyes Project" (a public security video surveillance project in China), intelligent transportation, water conservancy monitoring, and environmental protection monitoring are mostly installed outdoors. These devices are large in quantity, widely distributed, and vulnerable to harsh environments, man-made damage, and other factors, leading to high system failure rates and poor availability.
Traditional manual maintenance has the problems of high maintenance costs and low efficiency, making it difficult to ensure a high online rate of equipment. Against the backdrop of IoT and edge computing technologies, Chenmai Wisdom has launched the Intelligent Operation and Maintenance Cabinet Solution. This solution provides reliable power supply and environmental protection for outdoor electronic devices, and features real-time fault alarm and automatic repair functions, which significantly reduce maintenance costs and improve maintenance efficiency.
Traditional outdoor power distribution cabinets usually consist of rainproof enclosures, residual current devices (RCDs), lightning protectors, regulated power supplies, sockets, fiber optic boxes, optical modems, switches, camera power supplies, and other components. They are typically assembled by engineering contractors using products sourced from multiple suppliers, which gives rise to the following problems:
High failure rate: The cabinets integrate lightning protection devices, air circuit breakers, and other components from different suppliers through simple assembly, resulting in inconsistent quality.
Difficult maintenance: Equipment and cables are disorganized, making it hard to quickly locate faults. This also leads to disputes and buck-passing when handling faults.
Poor reliability: Secondary faults are prone to occur, making it difficult to ensure the equipment's online rate.
Low intelligence: They lack functions such as fault alarm, remote control, and self-repair, leading to high maintenance costs.
Poor security: There are no monitoring measures for illegal door prying, high temperatures, lightning strikes, or waterlogging.
According to statistics from a large amount of practical operation data, cabinet faults account for more than 90% of total maintenance work!
The Intelligent Operation and Maintenance Cabinet is an independently R&D and designed intelligent cabinet developed to meet the big data informatization management requirements in fields such as Safe Cities, electronic police checkpoints, expressways, and subway rails. It is an intelligent cabinet integrating functions including power supply and distribution, optical fiber access, lightning protection, environmental data collection, intelligent monitoring, and remote control.
Compared with traditional outdoor power distribution cabinets, it features higher integration, greater intelligence, and easier maintenance. In addition to meeting the basic functional needs of the original communication protection cabinets, this product incorporates Internet communication technology, smart city informatization management technology, modular design, lightning protection system design, and comprehensive and powerful data applications. These enhancements ensure the reliability, continuity, and intelligence requirements of the intelligent management cabinet and related system operation equipment.
This device is an all-weather outdoor electrical equipment protection cabinet designed for open-air environments. It features functions such as rainproof, dustproof, ventilation and heat dissipation, anti-aging, lightning protection, and anti-electromagnetic interference. The cabinet adopts a modular design, enabling easy installation and maintenance. It is the preferred management equipment for large and medium-sized cities that require big data management.
Combined with the central visualized operation and maintenance management platform, it realizes the visualization, controllability, and traceability of operation and maintenance data. It helps users establish a supervision mechanism covering monitoring, response, analysis, and management, effectively enhancing the support capability of business systems.
The intelligent operation and maintenance cabinet has five core functional features: intelligent environmental support, intelligent power supply and distribution, intelligent network management, intelligent maintenance alarm, and extensive expandability.
The intelligent operation and maintenance platform provides comprehensive and reliable supervision for various outdoor electronic monitoring systems. Cooperating with front-end IoT controllers, it helps users establish a supervision mechanism including monitoring, response, analysis, and management, effectively improving the support capability of business systems.
Multiple alarm methods such as voice, pop-up window, APP, and email are adopted to send hierarchical alarm notifications. It also supports work order assignment and asset management.
It enables full-lifecycle tracking and management of assets covering the entire process from "procurement - use - maintenance - scrap".
It supports mobile phone-based APP operation and maintenance. When maintenance personnel receive push notifications about fault work orders, they can click to accept and enter the automatic assessment process. The APP enables map positioning of fault locations, assesses indicators such as the maintenance personnel’s fault response time and repair time, and generates reports.
Combined with the platform’s inspection management function, it realizes tracking of the inspection process, query of inspection trajectories, personnel positioning and check-in, and management of maintenance requests. It also allows the upload of information such as voice recordings and photos during the inspection process.
