▶ Multi-loop single fiber structure: On the basis of single-loop single fiber, a multi-ring structure can be established. Each ring network is relatively independent. The primary splitter / combiner injects the signal from the concentrator into each ring network through the secondary splitter and combiner. The response information of the meter can be uploaded to the primary splitter / combiner through the secondary splitter / combiner and finally transmitted to the concentrator.

▶ Main features: The collection success rate is high, and the real-time performance is good. The ring network is generally based on the meter box. Each ring network has multiple meters.

▶ Applicable scenarios: centralized buildings, multiple meters in the meter box

Option II

▶ Hybrid network structure: According to the distribution of the meter position, a suitable ring network is selected and finally uploaded to the concentrator through a splitter / combiner.

▶ Main features: Cover a wide range of collections, compatible with various collection methods.

▶ Applicable scene: Various scenes can be applied.

Solution Brief

The equipment hierarchy of the plastic optical fiber collection scheme is similar to other acquisition schemes. It mainly includes acquisition and measurement equipment (that is, electricity meters), data processing and transmission equipment (that is, concentrators), and data processing centers (that is, master station equipment). Acquisition channel difference.

Dassault Fibre Solution uses plastic optical fiber (POF) as the communication medium between the collection and measurement equipment (smart meters) and the data processing and transmission equipment (concentrator), which effectively ensures stable and reliable communication, high real-time acquisition success rate, and remote pull-closing control Wait for a single operation to succeed.
