Shopping Mall Sub item Measurement Energy Consumption Monitoring System

SICET sub item metering energy consumption monitoring systemProvided technical support by Nanjing Swo 189 Ceramic 5244 Engineering 6334,The company has always adhered to the business philosophy of "innovation, integrity, collaboration, and progress" and the business purpose of "serving customers in everything", making Swo Electric a modern enterprise with strong cultural cohesion and brand influence in scientific management, technology, large-scale, and efficiency.

With the development of social economy, China's medical and health care industry has also made great progress. However, most of the buildings of some large hospitals were built in the 20th century, and the power supply system is generally built at the same time as the main building. There are problems such as equipment aging, multiple safety hazards, and low level of intelligence. With the increasingly widespread application of computer information technology in the power industry, managers are no longer satisfied with monitoring the operating conditions of power distribution sites only in fixed monitoring centers. The Nanjing Swo Power Monitoring System is based on a web architecture using a web browserSICET sub item metering energy consumption monitoring systemThe distributed structure of network application software ensures the maximum efficiency of the system.

The system is divided into four layers,oneThe layer is the equipment layer, which includes: power instruments and meters, microcomputer relay protection, photovoltaic inverters, intelligent switches, fault and waveform recording equipment, temperature inspection equipment, DC screens, etc.

The second layer is the collection layer, which collects and transmits data from devices in this area through communication interfaces and protocols through a front-end communication management machine, and transmits data to the upper layer through a standard Ethernet interface.

The third layer is the transport layer, which forms a network through switches to transmit data from collection devices in various areas through the network. Common types include star networks, ring networks, etc. Link media include twisted pair cables and optical fibers. Twisted pair cables can only form regional networks within 200 meters, while optical fibers are not limited by distance and can form complex, long-distance transport layer network media.

The fourth layer is the display layer, which provides graphical presentation effects through monitoring software to display the system's operating data. In addition to display, it also provides functions such as fault information collection, fault reproduction, historical data, waveform analysis, operation logs, and operation management. In addition to the monitoring center, real-time and data display is also provided to management personnel through WEB, mobile APP and other means.

Classification of energy consumption

Classified energy consumption refers to energy consumption data collected and organized based on the main types of energy consumed by government office buildings and large public buildings, such as electricity, gas, water, etc.

sub-item energy consumption

Sub item energy consumption refers to energy consumption data collected and organized based on the main uses of various types of energy consumed by government office buildings and large public buildings, such as air conditioning electricity, power electricity, lighting electricity, etc.

Large scale review

Big data auditing is the process of analyzing and comparing data to examine whether the data itself or its changes are in line with reality, and whether there are logical or trending errors; Is there any misalignment or multiple digits in the numerical values of the data, as well as incorrect decimal point positions.

Industry demand

According to the Safety Protection Regulations for Secondary Power Systems (Order No. 5 of the Electricity Regulatory Commission), horizontal single item safety isolation devices must be installed in the production control area and information management area of power grid enterprises to ensure safety. However, network operation and maintenance personnel generally work in the information management area and need to manually connect each system device in the production control area for operation. The operation is complex, and the two work areas are usually far apart, which is time-consuming and labor-intensive. In case of risks or failures, it is difficult to quickly detect problems. With the vigorous layout of new infrastructure projects, power companies urgently need network monitoring and operation products to improve work efficiency, reduce downtime events, and enhance service levels.
