1. The background of the scheme.
Most of the systems such as Xueliang engineering, smart transportation, water conservancy monitoring, and environmental protection monitoring are installed outdoors. The equipment is large in magnitude and widely distributed, and is easily affected by factors such as harsh environment and man-made damage, resulting in high system failure rate and poor availability. Traditional manual maintenance is the problem of high maintenance costs and low efficiency, and it is difficult to ensure a high online rate of equipment.
In the context of the Internet of Things and edge computing technology, Chenmai Wisdom has launched an intelligent operation and maintenance box solution, which provides reliable power and environmental protection for outdoor electronic equipment, and has real-time fault alarm and automatic repair functions, which greatly reduces maintenance costs. Improve maintenance efficiency.
2. Demand analysis
The traditional outdoor distribution box is usually composed of a rainproof box, a leakage switch, a lightning protection device, a stabilized power supply, a socket, an optical fiber box, an optical modem, a switch, and a camera power supply. Usually it is composed of multiple products purchased by the engineering company, and the following problems exist:
The traditional chassis has a high failure rate. There are many products involved in lightning protection and air switch, which are simple to piece together, and the quality is uneven;
The traditional chassis is difficult to maintain, the equipment and cables are messy, it is difficult to quickly locate the fault, and the fault handling is prevarication and wrangling;
Traditional chassis has poor reliability and is prone to secondary failures, making it difficult to guarantee the online rate of equipment;
The traditional chassis has low intelligence, lacks fault alarm, remote control, fault self-repair functions, and high maintenance costs;
The traditional chassis has poor security, and there is no monitoring method for illegal door opening, high temperature, lightning strike, and water flooding. Through a large number of actual combat data statistics, chassis failures account for more than 90% of maintenance!
Three, intelligent operation and maintenance box solution
The intelligent operation and maintenance box is an intelligent operation and maintenance box independently developed and designed to meet the management requirements of big data informatization in fields such as safe cities, electronic police checkpoints, highways, subway tracks, etc. It is a centralized power supply and distribution box. , Optical fiber access, lightning protection, environmental collection, intelligent monitoring, remote control and other functions in one intelligent chassis. Compared with the traditional outdoor distribution box, it is more integrated, smarter and easier to maintain. In addition to meeting the basic functional requirements of the original communication protection box, this product adds Internet communication technology, smart city information management technology, modular design, lightning protection system design, and complete and powerful data applications to ensure that the smart management box and related The reliability, continuity and intelligence requirements of system operation equipment.
The equipment is an all-weather outdoor electrical equipment protection box used in the open air environment, which has the functions of rainproof, dustproof, ventilation and heat dissipation, anti-aging, lightning protection, and electromagnetic interference prevention. The cabinet adopts modular design and is easy to install and maintain. It is the preferred management equipment for large and medium-sized cities that require big data management.
Combined with the center's visual operation and maintenance management platform, it realizes the visibility, control, and traceability of operation and maintenance data, and establishes a set of monitoring, response, analysis, and management supervision mechanisms for users, effectively improving the support capabilities of the business system.
The intelligent operation and maintenance box has five major functional characteristics: intelligent environmental protection, intelligent power supply and distribution, intelligent network management, intelligent maintenance alarm, and rich scalability.
Four, visualized intelligent operation and maintenance platform
The intelligent operation and maintenance platform provides comprehensive and reliable supervision for various outdoor electronic monitoring systems, and cooperates with the front-end IoT controller to establish a monitoring, response, analysis, and management supervision mechanism for users to effectively improve the supporting capabilities of the business system.
Overview view: The cockpit interface, which displays the overall status and trend of equipment operation in the area under its jurisdiction at that time.
Fault alarm: hierarchical alarm notifications through multiple alarm methods such as voice, pop-up windows, APP, and email. Work order distribution, asset management.
Statistical report: Tracking and managing the entire life cycle of assets "purchase-use-maintenance-scrap".
Handheld operation and maintenance APP: Support mobile phone APP operation and maintenance. When the operation and maintenance personnel receive the push notification of the fault dispatch, click Accept to enter the automatic assessment process, locate the fault location map, and evaluate the personnel handling fault response time and repair time. And form a report. Combined with the inspection management function of the platform, it can realize the tracking of the inspection process, the query of the inspection track, the personnel location sign-in, the maintenance request management, etc., and the voice, photos and other information during the inspection process can be uploaded.
