Keywords: environmentally friendly electricity; Monitoring; Cloud platform; Application 1 Cloud platform concept and characteristics Cloud platform refers to the database stored on the network server, the cloud platform is composed of hardware equipment and software, hardware equipment includes CPU, memory and server, etc.
, software includes integrated development software and application software
.

Cloud platforms entrust a large amount of data processing and data storage to a database of hardware and software
.

The core function of the cloud platform is to process and store a large amount of data in parallel, and the outstanding feature of the cloud platform is that it can be separated from manual operation, and the cloud platform can automatically manage and maintain a large amount of data and resources
in the cloud platform.

The cloud platform includes the following characteristics: (1) flexibility and scalability, the cloud platform can provide personalized, flexible and scalable services according to different regional scopes, software performance and hardware configuration, and can dynamically scale the scale of resources according to the number of platform access users to meet the needs
of different access customers.

(2) Data pooling, cloud platform relying on computer network virtualization technology to establish a cloud server cluster, with parallel processing storage, distributed processing storage and Internet communication and a series of powerful functions, access users are no longer limited by geographical location, users can access the data resources
of a service area and resource center in the data pool anytime and anywhere.

(3) Provide autonomous services, for users to provide services on the cloud platform is transparent, the hardware, software and data on the cloud platform can be configured autonomously according to the different needs of users, and customers can customize and purchase
according to the needs of autonomy.

(4) With high security, the cloud platform can use the local and regional replication functions to filter or remove spam information and excess information in the data, and can effectively overcome the problem of high network concurrency and network congestion, and use Traffic Manager to balance the data flow load accordingly, including traffic splitting, configuration and failover
.

2 The application of the cloud platform in the environmental protection electricity monitoring Ankerui environmental protection electricity supervision cloud platform relies on the Internet of Things and power parameter sensing technology, the data acquisition terminal obtains the power parameters of the power loop of the device, uploads it to the cloud platform through the DTU or digital meter, and visually displays the monitoring data in front of the user's eyes
through the Web page or APP.

The whole program detects and collects electricity and environmental indicators, saves and packages the parameters to form a standardized data package, and then uses the LoRa path to transmit to the cloud platform, and the template components of the cloud platform can monitor the software development, and the dynamic parameters are intuitively reflected to the interface
of the application software.

The cloud platform integrates the alarm function, which can achieve real-time release and push
of alarm information.

In addition to monitoring the working conditions of environmental protection treatment equipment and the production status during the suspension and limitation of production of enterprises, the system is also very suitable for environmental monitoring such as VOCs, soot, wastewater, etc.
, and can also integrate video or access control monitoring, which is worth applying and promoting
