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

Embodiment 1
[0031] Such as figure 1 As shown, the embodiment of the present invention provides a multi-head terminal communication conversion tail-end device based on HPLC carrier network, including: HPLC communication module, communication protocol conversion module and meter communication module, and the communication protocol conversion module communicates with the smart meter through the HPLC module The terminal connection is connected with the smart meter module through the meter communication module.
[0032] Described communication protocol conversion module is provided with tail conversion mechanism, and its concrete method is:
[0033] S1. After power-on, the frame listens to the network information of the head-end device and starts the network access application. At the same time, starts the automatic meter search mechanism, searches for the address of the downlink smart meter of the device, and stores the searched smart meter address, such as figure 2 shown. The communicatio...
Embodiment 2
[0040] Such as Figure 4As shown, the embodiment of the present invention provides a multi-head end communication conversion system based on HPLC carrier network, including a plurality of end devices, intelligent terminals and A first platform, where the first platform is used to add management files to the smart terminal.
[0041] Specifically, such as Figure 4 As shown, in this embodiment, the first platform communicates with the smart terminal through a 4G mobile network.
[0042] Specifically, in this embodiment, when the first platform adds a management file to the smart terminal, it only adds the communication address of the communication transformation end device. When the tail-end device accesses the network with its own communication address, it does not report the searched address of the smart meter to the head-end device, and does not use the address of the smart meter to access the network.
[0043] Specifically, such as Figure 5 As shown, in this embodiment,...
