Abstract

The embodiment of the invention discloses a communication success rate computing method and device of a power line broadband carrier. The inter-site link communication quality can be more reflected, the dynamic change of the link communication quality can be more accurately reflected, and the excessive fluctuation can be avoided. The communication success rate computing method of the power line broadband carrier provided by the invention comprises the following steps: S1, computing a downlink communication success rate through the message sent by a first site and the message number received by a second site in a predetermined routing cycle in the downlink communication, and computing the uplink communication success rate through the message number sent by the second site and the message number received by the first site in the routing cycle in the uplink communication; and S2, performing the product operation on the uplink communication success rate and the downlink communication success rate to acquire the communication success rate between the first site and the second site in the routing cycle, computing the communication success rate weighted mean between the first side and the second site in the latest routing cycle with predetermined number.

Description

technical field [0001] The present invention relates to the technical field of power line carrier communication, in particular to a method and device for calculating the communication success rate of power line broadband carrier. Background technique [0002] Power line carrier communication technology is referred to as PLC technology, which usually uses a modem to modulate the signal, and then injects the modulated signal into the power line for communication. Power line broadband carrier adopts OFDM modulation technology, and uses widely deployed power lines as communication channels, which can realize the connection of users' electric energy collection terminals to broadband communication networks without wiring and at low cost. [0003] In power carrier communication, the communication efficiency between different stations will directly affect the quality of data transmission. In uplink and downlink communications, in order to select a most efficient data link for data ...

Problems solved by technology

[0010] (1) The power user meter reading system selects the best path for message transmission based on the indicator of signal strength. There may be a phenomenon that the signal strength is high but the quality of the communication link is low, resulting in a high packet loss rate and reducing the packet loss rate. Completeness and Accuracy of Transmissions

[0011] (2) Although the definition of the communication success rate is simple and clear, the statistical cycle and calculation method of the communication success rate are still unclear

In some time-varying application scenarios, too short a statistical period will lead to large fluctuations in the communication success rate; and too long a statistical period will cause the communication success rate to fail to reflect the link communication quality in time, affecting path selection

[0012] (3) The communication success rate calculation of the existing method is one-way. In a two-way asymmetric environment, the one-way communication success rate cannot accurately reflect the two-way communication quality of the link
