Description

technical field [0001] The invention belongs to the technical field of electric power communication, and in particular relates to a multi-head end communication conversion tail end device and system based on an HPLC carrier network. Background technique [0002] Low-voltage power line high-speed carrier communication (High Power Line Carrier), referred to as HPLC, is a communication method that is stable, reliable, fast in communication rate, safe in data transmission, and can use power lines for data transmission. High-speed carrier communication has been vigorously promoted in the power industry. Its application effect has also been recognized by users, and it can increase network robustness. However, the power carrier communication in the prior art also has certain limitations. On the one hand, the application of power line broadband carrier communication in the collection of electricity consumption information, in the whole process of establishing the communication netw...

However, the power carrier communication in the prior art also has certain limitations

On the one hand, the application of power line broadband carrier communication in the collection of electricity consumption information, in the whole process of establishing the communication network, the same head end, that is, the master node device in the same network and multiple slave devices (such as smart energy meters) are jointly established in the The same communication network; on the same network, the head-end and the tail-end are networked, and the tail-end is installed on a different slave device and connected to the network to the head-end device, and can no longer be networked with other head-end devices, that is, the tail-end device only One head-end device can be connected to the network, which results in only one head-end device in the same network, that is, after the same tail-end device is connected to the network, its data can only be read by one head-end information

[0003] On the other hand, with the continuous promotion of the large-scale application of HPLC broadband carrier by the State Grid Corporation of China, the demand for intelligent operation and maintenance of low-voltage power distribution systems continues to increase, and the same intelligent Multi-network transmission of electricity meter measurement data, the demand for multi-platform data analysis is getting higher and higher, and a single head-end device can no longer meet the current application requirements. Therefore, multiple head-end devices in one station area operate and obtain the same smart meter data. Issues that urgently need to be resolved

[0004]In addition, in the existing smart meter reading system in the low-voltage station area, during the HPLC networking process, after the address of the smart meter is connected to the network, the head-end device needs to manage the network address , because the communication address of the smart meter in the network is only allowed to enter the network on one head-end device, when a head-end device is added in the station area to read the smart meter, both head-ends must manage the communication address of the smart meter, resulting in the smart meter device being in the archives There are conflicts in management, and the reading of smart meters cannot be realized at the same time
