(3) The system should have expandability in terms of system capacity, communication capability, processing capability, etc., which can facilitate product upgrades, replacements, and functional expansion.

The system adopts advanced technology, methods, and equipment to provide open standard interfaces for third-party applications.

In future upgrades, it can effectively protect existing investments and has a high comprehensive performance price ratio.

(4) The system can operate normally 24 hours a day, 365 days a year, and all equipment has high reliability and excellent performance.

(5) The system has high security and confidentiality, and various forms of illegal intrusion into the system are prevented through graded protection, control of data storage permissions, and network security isolation.

(6) The system administrator is able to maintain and manage the system, and during maintenance and repair, it does not affect the overall business operation of the system.

At the same time, all documents of the recording system must be complete, accurate, and consistent, and the accuracy of physical connections must be accurately recorded in the corresponding documents.

In addition to accurately recording themselves, various documents must also ensure logical consistency between each other.

Facilitating user maintenance after handover.

System network structure

The system adopts a three-layer available structure, which can complete both terminal layer data collection and on-site data collection, and can send data to the cloud platform. The entire topology diagram is as follows:

Main features

(1) Standardization: The design of the entire monitoring system complies with national or international standards.

The system software and hardware adopt standardized design, provide open interfaces, and can interconnect with devices and software systems from different suppliers.

(2) Stability: The energy data collector adopts an embedded real-time Linux operating system and a dedicated hardware structure, with stable and reliable performance, ensuring the overall stability of the system, especially suitable for running in complex environments with high reliability requirements.

The WEB system platform adopts the professional development framework of J2EE in the industry, which meets the needs of big data collection, large capacity data storage, and high concurrency data access requests.

(3) Progressiveness: based on the design concept of configuration software, with a set of general platform, it solves the problems of photovoltaic data acquisition, local SCADA monitoring, cloud platform data analysis, and mobile app operation and maintenance management.

The four-dimensional integrated solution promotes the intelligence of distributed photovoltaic operation and maintenance platforms.

(4) Practicality: Based on a real-time database, it can monitor multiple users and screens in real-time, remotely control, and connect multiple alarm devices to fully meet the monitoring requirements of users.

(5) Security: The security of platform monitoring systems is one of the key issues in management. Security is divided into data security and information security, and there are the following requirements in the above three aspects:

●Data security: Store data at multiple levels and in a distributed manner, making it less susceptible to damage. The AES encryption mechanism for data ensures the security of data during network transmission, preventing interception, tampering, and exploitation;

●Information security: All configuration information, management information, and log information are stored in the central database for centralized information management;

●Hierarchical authorization: Authorize the application functions and access scope of subordinate administrators. Authorize and manage the application functions and access scope of the operators of the affiliated institutions by subordinate administrators.

(6) Scalability: The entire system has the ability to further expand its functionality and can adapt well to the needs of modern intelligent control. Ensure effective development and use of the system by users, and provide a favorable environment for future development.

Can fully utilize and protect existing network resources for current and future expansion;

The platform server has the ability to expand and stack, facilitating the integration and expansion of centers at different levels. The system must have strong monitoring points and storage space expansion capabilities.
