AMI G3-PLC Communication Module for Single Phase Meter Power Line DC2-PSR4

Company Profile

Willfar Information Technology Co., Ltd.

- Established in 2004;
- Listed on the STAR Market of the Shanghai Stock Exchange in December 2019;
- Leading supplier of meter reading (AMI) equipment and operation service;
- The first company to develop "One DCU Reading Multi-meter" solution in China;
- The first company to have large-scale application of technologies and systems like "CPU smart-card Charge and Control", "One DCU Reading Multi-meter", LoRa-based RF Communication and "District Metering Area (DMA)”

Introduction

- G3-PLC is an open power line communication module designed for smart grid communication. Its physical layer is based on OFDM modulation and complies with G3 standards.

- G3-PLC have high-speed communication, strong anti-interference ability, the communication speed is much faster than traditional PLC.

- The module has very low maintenance cost. Metering reading network operating with G3-PLC is automatically constructing, automatically addressing and route maintenance.

- It can be easily integrated in smart electric meter to provide the AMI function.

- DC2-PSR4 could be adopted to Single Phase Electric Meter.

Technical Parameter

Certificate

G3 PLC/ IEEE1901.2/IEEE802.15.4-2006/6LoWPAN/ITU G.hn/S-FSK (IEC 61334)

Features

1. OFDM-based PHY (BPSK, QPSK, 8PSK) makes efficient use of the spectrum

The "robust" mode of module improves communication under noisy channel conditions, operates at -15 dB SNR.

2. Compliant with world regulatory bodies such as CENELEC, ARIB, and FCC (10 kHz - 490 kHz)

Auto switch between CENELEC-A and FCC to adapt different scenario according to the DCU.

3. Standards based — pre-standard in IEEE, ITU, IEC/CENELEC and IEC/SAE

- Two layers of forward error correction (FEC) for robust data communication in harsh channels.

- Adaptive tone mapping for optimal bandwidth utilization.

- Channel estimation to select the optimal modulation scheme between neighboring nodes.

- IEEE 802.15.4-based MAC layer well suited to low data rates.

- 6LoWPAN adaptation layer to transmit IPv6 packets over powerline channels.

- Coexistence with older S-FSK (IEC 61334), and broadband IEEE P1901 and ITU G.hn standards.

- Supports IPv6 to allow Internet-based energy management systems and applications.

4. Security

AES-128 cryptographic engine for optimum data security.

5. Mesh routing protocol to determine the best path between remote network nodes

- The maximum nodes 1024

- The maximum hops 14

6. Over the Powerline update Firmware (OTP)

7. DLMS interface with meter

8. G3-PLC alliance Certified products

Situation

For Single Phase Smart Electric Meter, Data Concentrator, or other communication instruments.

Introduction

As the first company in Hunan Province to be listed on SSE STAR Market, Willfar is the pioneer manufacturer in China that can simultaneously provide related industries with all kinds of advanced electricity, water, gas and heat metering products and meters for power distribution, power quality monitoring equipment, a full range of energy data concentrators, relay protection equipment, switchgear products and equipment related to metering automation system and all kinds of application systems as well as services which cover the demand of the whole process of energy production, distribution, transmission and consumption.

Willfar Information Technology Co., Ltd always focuses on customers and takes full control of products’ delivery and deployment, including the process of designing, testing and experimenting as well as the manufacturing process of raw material. We attach great importance to production control plan, potential failure mode and product reliability design which require us to implement the production approval procedure and control the production process strictly so as to ensure the products’ quality.

On November 4, 2013, President Xi Jinping, also general secretary of the Communist Party of China (CPC) Central Committee, visited Wasion in Changsha. He visited the product showroom and production workshops, where he talked with workers and labor models. Xi spoke highly of Wasion's achievements in product development and market expansion and encouraged the company to step up innovation in technology, management, product, marketing and branding.

So far, Willfar has 396 valid patents, of which 26 are invention patents, 240 pieces for utility model, 130 pieces for design and 442 software copyrights; it has also received 10 technical awards of provincial or ministerial level or above. Willfar has participated in the setting of 15 national industry standards, 10 of which have been published.

Willfar Information Technology Co., Ltd takes "smart manufacturing capability" as one of its core competing powers by realizing the whole process data tracing and full-lifecycle management of product design, processing, procurement, production, logistics and service via SCM, CRM and APS on the basis of ERP, PDM, PLM and MES.
