Description

Technical field [0001] The invention relates to a plastic optical fiber dual-mode collector based on an optical fiber interface and a LoRa interface, and belongs to the technical field of optical fiber dual-mode collectors. Background technique [0002] The electric energy information collection system has been developed in China for more than 20 years. The main communication methods are: RS-485 wired technology, low-voltage power carrier and wireless dual-mode communication, broadband carrier, and short-distance wireless communication. However, these communication methods have certain shortcomings. Low-voltage power carrier communication has insufficient real-time stability. RS485 bus communication has weak anti-electromagnetic interference and lightning resistance. Short-distance wireless communication is susceptible to weather changes and buildings. Broadband carrier is not yet available. A lot of operating experience, stability needs to be proven. Currently based on carrier ...

Problems solved by technology

However, these communication methods have certain defects. The low-voltage power carrier communication has insufficient real-time stability, the RS485 bus communication has weak anti-electromagnetic interference and anti-lightning strike capabilities, and short-distance wireless communication is easily affected by weather changes and buildings. Broadband carrier has not yet A lot of operating experience, stability to be proven

At present, based on carrier and micro-power wireless dual-mode, broadband carrier and other centralized copying technologies, it can meet the basic copying rate index requirements, and the daily average acquisition success rate barely meets the standard, but the communication capability of the existing technical solutions has basically reached the bottleneck, and cannot be further upgraded. Supports the requirements for true remote real-time communication
