Application of time series database in intelligent power consumption field

Hello, everyone , In the containment of the epidemic, we met again , In this issue, we continue to talk about the application of time series database , Chat TSDB Application in the field of intelligent power consumption . 

This article only represents personal views , If there is bias , Please ask Hai Han. ～

Now , Whether it's life or production and operation , We are inseparable from the use of power equipment , Using electricity has become a very common behavior in our daily life , But what many people may not know is , In the process of using electricity, we also face various risks , such as The power of the electric appliance is greater than the carrying capacity of this circuit , Another example Using electrical appliances for a long time causes the temperature of some lines to be too high etc. , These seemingly infrequent problems , Has always been a major safety hazard .

therefore , Smart electricity came into being , It is an intelligent supervision process for lines and electrical appliances in the process of power consumption , It uses the Internet and big data technology , The realization of people to people 、 Real time information exchange and ubiquitous contact between people and things and between things . such as , It collects the current generated during the operation of the line 、 voltage 、 temperature 、 Electricity consumption and other data , And use the big data analysis function to analyze and judge these data , Find the potential safety hazards on the electrical lines and electrical equipment in real time, and send the alarm information to the user management personnel in real time , Guide users to carry out governance , Eliminate hidden dangers , To achieve the purpose of prevention . meanwhile , It also supports leakage 、 Over current 、 A short circuit 、 overload 、 Overvoltage 、 Undervoltage and other multi-purpose electrical protection , And missed self inspection , Power limit , Electricity calculation .

Smart power platform architecture

Smart power platform provides a comprehensive solution for electrical safety supervision and energy data management . Through the intelligent terminal equipment of the Internet of things , Integrated electrical 、 Fire and other sensors , And compatible with NB-IOT and MQTT And other communication protocol modules , Finally, a cloud platform for big data analysis service of Internet of things has been formed . Intelligent terminal equipment of intelligent power consumption platform , Highly integrated product functions such as fire and electrical monitoring , We only need to install it on the user's distribution cabinet or the distribution box at the end to realize real-time 、 Accurately collect the data of various electrical parameters of the line （“ Perception layer ”）, And send the data through the wireless communication module MQTT The protocol is uploaded to the time series database of distributed deployment （“ Transport layer ”）. Then the application platform analyzes the received timing data （“ Platform level ”）, Through WeChat 、 SMS 、App Send the early warning information to the user in time by means of message 、 Responsible person 、 Managers, etc （“ application layer ”）, In order to investigate and eliminate potential safety hazards in time .

Smart power safety management

When we check and locate fire and other potential safety hazards through the business analysis platform , The risk assessment result will be sent to the user terminal , Remind and guide users to deal with potential safety hazards . Through the electrical data recording of massive online terminal equipment , Accumulate and form big data of safe power industry , In order to analyze , It can effectively evaluate and predict power consumption 、 Trends such as power safety . meanwhile , Users can also check the current of their access terminal at the smart power client 、 Real time detection of current and temperature , And trend data of equipment operation status , View the alerts and expert suggestions pushed by the platform . Managers can view the residual current of the monitored equipment at the functional end 、 Data changes such as conductor temperature and current , If potential safety hazards are found in the dynamic operation of electrical lines , It can respond and dispose in time . The smart power platform can also turn on the alarm according to the preset , Predict and analyze the operation state of electrical circuit in intelligent mode , On the basis of data analysis, early warning information is sent to all users in time , Make electricity safety more intelligent .

At present, smart power consumption is mainly piloted in industrial parks , Mainly because first, industrial electricity is more expensive than domestic electricity , Second, the risk factor of industrial power consumption is high , Once in danger, life and property will be greatly affected , Third, the informatization foundation of the industrial park is better and more suitable for unified planning . Using time series database for corresponding monitoring can effectively reduce electricity charges and electricity risks , And reduce the pressure of property operation in the park . Such industrial parks 、 Power generation enterprises 、 Power grid companies 、 Enterprises in the park 、 The local fire officers and soldiers benefited from many things .
