1.2 Communication Protocol:

1) Supports MQTT and Modbus protocols.

2) The communication protocol library is extensible.

1.3 Deployment Method

1) Support localized deployment;

2) Support private cloud deployment;

3) Support public cloud deployment;

1.4 Overall System Functions

1) Equipped with real-time data information display, historical data query, alarm function, electricity bill report, communication working condition, operation and maintenance management, equipment management, permission service, account management, etc;

2) Capable of collecting, storing, and querying system and user logs.

3) Alarm notification information can be sent through SMS, email, and other means.

2 System Architecture:

1. Backend data middleware technology architecture:

-Build a microservice architecture using Spring Cloud to achieve service splitting and independent deployment;

-Using MySQL as the primary data storage;

-Using Redis as cache storage to achieve data caching;

-Use MQTT as the Internet of Things protocol to collect and process device data.

2. Front end technical architecture:

-Using Vue2 as the front-end framework to achieve data display and user interaction;

-Using Element UI as a UI component library to achieve rapid development and aesthetically pleasing UI interfaces;

-Use Axios to achieve front-end and back-end data interaction.

3. Operation and maintenance technology architecture:

-Use Nginx to achieve load balancing, request distribution, and resource optimization;
