Benefit Energy Situation outstanding, requires according to national energy management system GBT23331 and international energy standard ISO50001 systems,
Intra-company should carry out energy efficiency indexes on-line examination to full level of factory, factory level, workshop level, deployment grade, to emphasis energy equipment energy
Source efficiency management reduces energy consumption, and to reach reduction production cost, reduction social resources utilize, reduction carbon dioxide is arranged
It puts, enterprise competitiveness, realizes Sustainable Development of Enterprises.
Energy administration of energy conservation mainly has two aspects on the market at present：
First, replacing the electrical equipments such as energy-saving product such as high energy efficiency lamps and lanterns, air-conditioning, achieve the goal by the way that product is energy saving, it is desirable that useless
Abandonment of aged old product, replaces new equipment, not only brings comparable waste, but also new investment is higher, and client's acceptance is not high.
Second is that increase control system, and additional sensor network and control assembly on existing equipment, Sensor monitoring work
State, controller are responsible for power switch or fine tuning, reach energy saving purpose.However, current this control system on the market, main
The operation data of traditional wireless communication technique (GPRS, 4G, Zigbee etc.) transmission pipe network is used, not only power consumption is big, monitoring
The longtime running effect of device is difficult to be protected, and transmission range is shorter, needs to connect by many relay transmission nodes
Large number of monitoring device is layouted limited there are monitoring point, and monitoring capacity is limited, pre-control scarce capacity, networking cost height etc.
Problems, data monitoring effect is undesirable, has greatly affected the daily maintenance effect of energy management system.
Narrowband Internet of Things（Narrow Band Internet of Things, NB-IoT）It is Internet of Things field in recent years
Emerging transmission technology, consumption bandwidth is small, supports the efficient connection of low power consuming devices, has and covers the spies such as extensive, at low cost
Point.In view of this, it is necessary to a kind of more effective enterprise energy management system is being proposed, to solve the above problems.

System software and visualization, system software call the data in database, pass through comparison, statistics, analysis, meter
It calculates and the Visual Implementation is to enterprise energy management.
Further, further include enterprise's MES system, communicated to connect with prepositive communication computer, dock production information.
Further, the database includes object library, the object library docking business goal, workshop target, teams and groups' mesh
The target datas such as mark, station target and far and near target.
Further, the database includes java standard library, the java standard library docking national standard, professional standard, enterprise's mark
The normal datas such as standard, foreign enterprises standard.
Further, the monitoring and metering terminal is connect by RS485 interfaces with data collector, and data collector passes through
Narrowband Internet of Things transfers data to prepositive communication computer.
Further, the monitoring and metering terminal directly transfers data to prepositive communication computer by narrowband Internet of Things.
Further, the prepositive communication computer is connect with enterprise MES system by api interface.
The beneficial effects of the invention are as follows：Compare the prior art, a kind of enterprise energy based on narrowband Internet of Things of the invention
Management system, by with can equipment and with can monitoring and metering point installation with can monitoring and metering terminal, in real time monitoring with energy equipment
With with can monitoring and metering point real time data, and transfer data to prepositive communication computer, database purchase prepositive communication computer obtains
Data, system software call data after by comparison, statistics, analysis, calculating and the Visual Implementation to enterprise energy pipe
Reason reduces production cost, the utilization of reduction social resources, reduction CO2 emission, enterprise competitiveness to reach, realizes enterprise
Industry sustainable development；Carried out data transmission using narrowband Internet of Things, there is stronger wall penetration capacity and extremely low power consumption, it can
To extend the service life of the on-line monitoring equipment of long-term work outdoors.
