Description

technical field [0001] The invention relates to the technical field of power transmission communication, in particular to a low-voltage power line high-speed carrier-to-Bluetooth communication system and method. Background technique [0002] At present, High Power Line Carrier (HPLC) for short is a communication method that is stable, reliable, fast in communication rate, safe in data transmission, and can use power lines for data transmission. It uses OFDM modulation, and the communication frequency band The range is 0.7M-12M, which effectively avoids the low-frequency noise of the power line, and has the effective characteristics of good anti-interference and strong robustness. In addition, using the power line communication method, data transmission can be completed by using the existing power line without rewiring. With the continuous development of low-voltage power line high-speed carrier communication technology, in order to complete the data interaction between powe...

Problems solved by technology

[0003] At this stage, due to the interconnectivity of HPLC communication manufacturers, the current operation site is mixed with various solutions, the on-site operation and maintenance debugging tools are inconsistent, and the interface is not uniform and unfriendly, which brings great inconvenience to the on-site operation and maintenance personnel; On the other hand, with the development of new intelligent stations, the demand for ubiquitous Internet of Things and edge computing is becoming more and more intense. The existing circuit breakers in traditional stations do not have communication interfaces, so they cannot effectively monitor household meters; The developed circuit breaker has a RS485 communication interface or a small wireless communication interface, but the RS485 bus communication method is complex in site construction and prone to errors, while the small wireless communication method has the problem that adjacent meter boxes are not easy to cluster. Brings certain difficulties to the analysis of on-site physical topology
