Problems solved by technology

Some manufacturers also use automatic relay technology, but because it is a completely master-slave question-and-answer method, the MAC layer (media access control layer) of the protocol used does not have the CSMA (multi-access carrier sense) mechanism and cannot support broadcasting. Answer, with the increase of installed electricity meters in the system, the workload of the automatic relay algorithm process of the concentrator increases geometrically, which makes the automatic relay of the concentrator consume a lot of time and space resources, which cannot meet the practical requirements

Abstract

This invention discloses one low voltage load wave integral network and its combination method, which comprises the following steps: testing integral part and its points communication quality; according to test results, setting first sub network communication quality better or equal to first preset value one point as second sub network r J>1 point; setting the other points as first sub network common points; when J>1, executing j sub network router point and its communication quality.

Description

technical field [0001] The invention relates to a low-voltage carrier centralized network and its networking, sending and receiving methods, in particular to a low-voltage power carrier meter reading system utilizing a downlink channel (low-voltage power line medium) and its networking, sending and receiving methods. Background technique [0002] The low-voltage power carrier wave meter reading system is a system that uses the existing low-voltage power network as a communication medium to automatically read the data of the meter. The power line network is the most widely distributed as a communication medium. The construction of the meter reading system is simple and low-cost. The best communication resource for meter reading systems. Figure 1 shows the basic structure of a typical low-voltage power carrier meter reading system on the power grid side, and Figure 2 is a schematic diagram of the concentrator governing the low-voltage electrical appliances of each household, w...
