Terminal monitoring unit: composed ofPower quality monitoringdeviceTo complete.

Communication service system: mainly composed of a monitoring instrument communication system, a communication server, and a communication module. The monitoring communication system is responsible for receiving communication server instructions, parsing instructions, searching and packaging required data, and uploading them to the communication server through the communication module. The communication server is responsible for all data communication with the power quality monitoring device and supports communication methods such as Ethernet interface and USB interface.

Database service system: mainly composed of a database, internal processing programs, and database management modules. The database is used to store monitoring data uploaded by various power quality monitoring devices in the power quality monitoring and analysis system. The database also provides data retrieval and other data service support for the monitoring and analysis platform in the system. The database supports large databases such as MSSQL and ORACLE.

Monitoring and analysis platform: mainly composed of online monitoring, power quality analysis, and parameter setting management. Online monitoring is mainly responsible for updating real-time records of monitoring power quality data, and refreshing real-time data every 3 seconds according to national standards. Power quality analysis is mainly responsible for numerical table, curve analysis, and report printing processing of statistical analysis data. Parameter setting management is mainly responsible for setting and managing various parameters of the system and power quality monitoring devices.
