The critical value of decay, sets frequency spectrograph peak-peak to keep, and is ordered when being sent from concentrator to ammeter without the broadcast pair for returning to frame,
Frequency spectrograph signal amplitude is recorded, carrier wave receiving sensitivity is designated as, to avoid the time-varying contingency of carrier communication, can repeatedly monitor
Sensitivity, takes mathematical mean.
3. networking time detecting is route, existing routing iinformation in concentrator is removed.Measurement point in concentrator is reset to join
Number, and will issue the deadline and be designated as routeing networking time started, cycle lasting copy reading ammeter data, when the success of copy reading data
After rate reaches more than 90%, the networking end time is designated as.The time difference of end time and time started are calculated, is designated as routeing networking
Time.
4. route relaying depth detection, gradually increases attenuation amplitude between concentrator and ammeter at different levels, finds maximum and declines
The critical value subtracted, and the maximum attenuation critical value is arranged on attenuators at different levels, by the start and stop to upper level ammeter and under
Whether one-level, which can successfully copy, is seen ammeter data, to verify presence and its depth of route relaying relation.
5. frequency hopping communications is detected, carrier communication center frequency point is using fixed frequency, and easily being disturbed by power grid environment is influenceed,
Therefore carrier communication center frequency point frequency is become two by some carrier wave manufacturers, even more than.In basic frequency by noise jamming
In the case of, sub-frequency point can be jumped into automatically, to avoid noise, improve communication success rate.Made an uproar by passband attenuation and band logical amplification
The technologies such as sound, it may be verified that the frequency hopping communications ability of carrier module.
6. the detection of routed path selection, to adapt to the complexity and time variation of power grid environment, carrier communication network is general
Design is with complicated routed path algorithm.To examine carrier communication routed path adaptability, by between original path
Apply interference and decay so that original path direction is unable to reach, test carrier networking could pass through other routed path directions
Reach destination node.As shown in Fig. 2 original Between path, apply a certain amount of interference and decay so that nodeIt is right
NodePath is blocked and can not reached, and can detection communication pass through Or other paths and complete meter reading communication, and
The time required to investigating its path changeover.
Routing node changes detection scheme in existing carrier network, increases new ammeter node, the newly-increased node of detection can
It is no to be automatically added in existing carrier network communication, and the time that newly-increased node adds network is investigated, similarly, pass through the deletion of node
Routing iinformation interior joint information is examined to reject and its rejecting time, the ability to transform in relative influence node-routing path.
Verification test process is averaged using multiple test, test result values.
It is logical with whole carrier wave the invention reside in a kind of low-voltage powerline carrier communication emulation detection analog network system is set up
Communication network is overall object, and the application process of analogue simulation carrier communication meter reading, using result of practical application as foundation, is realized to not
Simulation detection and analysis in same model carrier module net, examines each module meter reading network in different signal interference and Reduction Level feelings
Actual meter reading effect under condition, is realized by each model carrier communication module property indices of lateral comparison and carrier module is examined
Survey, the carrier communication module and its meter reading performance of different vendor are compared and effect judgement so as to realize, are electric power enterprise
Examination provides effective foundation from high-quality and efficient communication products during building automatic meter reading system.Structure design of the present invention is new
It is clever unique.
