Zhengzhou Runner Electric Co., ltd. is a high-tech enterprise with R&D, Production, Manufacture and Sales departments and we dedicate to automatic and intelligent electric power. Now our products have a leading market share after nearly 10 years’ development. We continuously pursuit technical innovation, and try our best to meet customers’ requirements in electric power automation and intelligence with our advanced technology, reliable products and best service.
Runner Smart Grid AMR (automatic message recording )System as one of the R&D products which we focus on electric and intelligent and has concentrator and collector two parts. It compliance with Q/GDW and DL/T. The products embodies our years’ accumulated technology and staffs’ collective wisdom. It has the advantages of mature technology, multiple functions, stable operation and strong signal confidentiality. So it is the best choice for set copy project of low-voltage used in residential users.
1.High success rate in meter reading: The success rate is above 99％at the first time, and second time 100%.
2.Easy installation and maintenance: concentrator, collector, wireless electric meter and 485 electric meter can establish network, provide route , learn and repair& manage the path automatically.
3.Real-time:The response time is 4s when collect and copy node on site while the time is 8s in backstage.
4.High security: internal communication adopts the encryption data to ensure the communication security.
5.Wide network coverage: Offer 16 routes, long distance.
6.Wireless FM interference:8 channels realize automatic frequency hopping, hardware watchdog, TCXO, strong anti-interference ability.
7.PLC adopts filtering measures to reduce error rate and resist interference.
8.High effective data transfer rate: the effective length transmitted by data-frame can get 2400 bit.
9. Stable and intelligent network: MANET has the stable network so that any node can be repaired automatically.
10.Large network capacity: The capacity is 1500 network nodes.
11.Wireless& free spectrum : 470MHz free spectrum, good communication distance and penetration.
12.Crrier-current can directly use power line to communicate, so it can reduce the wiring trouble.
13.Can form different methods according to the application:
concentrator+ carrier table +wireless table.
The system can realize the no clearance communication between the collector and concentrator by wireless or PLC(power line carrier) communication module installed in the communication warehouse. Devices in the warehouse can build communication network automatically and the network have the function of self-healing and self-learning without manual intervention.
The system can collect, sort and store the following data: It can freeze data at the end of the day(0:00)/ month and each month(0:00, the first day /month)/year， and support multi-rate meter. The frozen data includes : Total, sharp, peak, flat, valley, voltage, current, power, power factor and other quality data.
