HPLC-based point-to-multipoint network data transmission method and system

Abstract

The invention discloses an HPLC-based point-to-multipoint network data transmission method and system, and the system comprises a system communication terminal, a gateway and a data service flow part; the system communication terminal and the gateway take a special network processing chip as a main control unit, are associated with an acquisition equipment interface, and perform data transmission through an HPLC, an Ethernet and a 4G communication interface; and the complex environment communication requirement is met. The invention relates to a point-to-multipoint network data transmission method and system based on HPLC, and belongs to the field of electric power communication. An HPLC communication terminal and an HPLC communication gateway can be in butt joint, communication transmission can be better carried out under wide butt joint, and the network communication rate requirement of acquisition type terminal equipment with low rate requirement can be completely met; data of equipment in a connectable environment can be collected, the data is transmitted to an HPLC communication gateway through a power cable in a point-to-multipoint mode realized by an HPLC module, and the communication gateway transmits the data to a cloud management platform through 4G wireless.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a network transmission method and system based on a HPLC point to multi-point. Background technique [0002] With the rapid development of wireless communication technology in recent years, narrowband WAN technology is more extensive, in complex environments, in complex environments, with multi-layered underground environment, or signal shields In a strong environment, the wireless signal only has a weak signal or even. The terminal communication devices in such environments have the following problems: 1) Similar wireless signals and their weakness or even at all, even Lora, NB-IOT and other terminal devices cannot be Data transfer to the ground or elsewhere; 2) When the terminal device data cannot be transmitted through wireless transmission, it can only be handled by professional maintenance workers, and the human investment of the entire project or project is...

AI Technical Summary

Problems solved by technology

Many terminal communication devices in such environments have the following problems: 1) Similar wireless signals are weak or even not covered at all, even LORA, NB-IoT and other terminal devices with strong penetrating signals cannot communicate The data is transmitted to the ground or other places; 2) When the data of the terminal equipment cannot be transmitted wirelessly, it can only be processed manually by professional maintenance staff, which requires high manpower investment for the entire project or project and higher maintenance costs. Moreover, the workload is large and the efficiency of implementation is low; 3) If the public network signal is enhanced through the operator, the construction cost will be high, and a large number of facility renovations will be required, which will destroy the original design and related facilities and possible hidden dangers. The increase in signal is not very obvious
