Low-voltage power grid carrier intelligent control system master station

Abstract

The invention relates to a low-voltage power grid carrier intelligent control system master station, which comprises a three-phase low-power consumption carrier transmitting and receiving module, an adaptive networking algorithm module, an adaptive multiband communication module, a PA power amplifier module and a data transmission and compilation module. The master station is connected with power lines of a three-phase three-wire system, a three-phase four-wire system or a three-phase five-wire system, a node in each level of the master station can be expanded to N (N=2n, and n=0, 1, 2...) nodes, a network system master station with two-way power carrier ad hoc network and multiband communication is thus formed, communication with a system control central station can also adopt interfaces such as a TCP / IP, wireless link communication, a CAN bus and an RS-485 data bus for realization, substations are organically organized through setting different network permissions, and T-type, Y-type and tree-shaped optimized networking topological forms for the network are realized. As for a complicated field environment or a communication island, a wireless communication form is combined, the field power line is made full use of, and high-efficiency and energy-saving and cooperative work is realized.

Description

technical field [0001] The invention relates to a master station of an intelligent control system, in particular to a system master station of a carrier industrial control system based on a low-voltage power grid with complex working conditions. Background technique [0002] With the development of industrial technology 4.0+ Internet technology, more and more network control of industrial electrical equipment has been used in the field of industrial production automation applications. Most of these control systems are connected by centralized controllers through GPRS point-to-point data interaction, for example, the user terminal of electric power meter is such a communication mode. This working mode is only used for meter reading and local street light control of electric energy meters in residential areas and commercial offices, and cannot be applied to every device in the industrial site, let alone the equipment control in the working environment of electromagnetic interf...
