Product Introduction

The TTU is an intelligent integrated terminal (hereinafter referred to as "terminal") that combines power supply and consumption information acquisition in distribution transformer areas, data collection from energy meters or acquisition terminals, equipment status monitoring and communication networking, on-site analysis and decision-making, and collaborative computing. It adopts a unified standard system development environment, achieving full software/hardware decoupling. It supports an edge computing framework, with terminal functions implemented as application software to meet the flexible and rapid development needs of power distribution and consumption services.

Key Features

The intelligent TTU satisfies both marketing and distribution business requirements. It adopts container and edge computing technology, incorporates dual security chips, and serves as the bridge between edge devices and the cloud master station. It supports HPLC acquisition, RS-485 communication, LTE communication, and other capabilities.

The intelligent TTU possesses all functions of traditional TTUs and concentrators. It is a key edge computing node for power distribution and consumption, the foundational intelligent IoT device in the cloud-pipe-edge-end architecture of the low-voltage distribution IoT, and provides edge IoT proxy, status perception, and data acquisition functions. It supports State Grid marketing, distribution, and emerging business areas.

The intelligent TTU adopts a hardware-platform-based, service-APP-based, and modular-structure design. It can be applied as an intelligent transformer terminal that integrates functions such as perception of operating equipment status in the distribution IoT, electricity data collection, transformer monitoring, communication networking, and localized analysis and decision-making mechanisms.
