Problems solved by technology

Due to the random input and withdrawal of a large number of loads in the low-voltage distribution network, the input impedance of the power line is uncertain, the noise interference is large, and the signal is selectively attenuated. The communication link is often interrupted, the communication range is reduced, and the reliability of the power carrier communication is reduced. , further affecting the effectiveness of data collection
[0003] The basic routing addressing is to search down from the nearest point bit by bit, so the time is slow, the cycle is long, the routing link is not stable, and it is prone to long delay and high packet loss rate.
The single ant colony algorithm has the problem of slow convergence and easy to fall into local minimum

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a meter reading routing addressing method based on a spiral algorithm. Background technique [0002] The low-voltage power network has the advantages of wide distribution and easy access. Low-voltage power carrier is a kind of low-voltage power line as the data communication medium, which integrates modern advanced measurement, communication and network technologies. Due to the random input and withdrawal of a large number of loads in the low-voltage distribution network, the input impedance of the power line is uncertain, the noise interference is large, and the signal is selectively attenuated. The communication link is often interrupted, the communication range is reduced, and the reliability of the power carrier communication is reduced. , further affecting the effectiveness of data collection. [0003] The basic routing addressing is to search down bit by...
