Technical field
Present invention is mainly used in the implementation of power information acquisition system, user's power-off event is realized using bandwidth carrier
The function of reporting, belong to management information system of power-consuming field.
Background technology
At present, in the market uses narrowband carrier mode to gather the modes of electric energy meter data, because narrowband carrier communicates frequency
The reason for rate (being generally less than 500kHz) limitation, can not be when user has a power failure, by way of signal coupling, by outage information coupling
The other end of table preceding switch is closed, system can not perceive power-off event in power down, can only can just be reported after electricity on user
Power-off event, the requirement of power-off fault fast reaction can not be met.
The content of the invention
The present invention is directed in current power information acquisition system, can only be stopped upper electric event to terminal and be monitored in real time, and
Electric energy meter power-off event can not be reported in time, especially list is only or more electric energy meters power failures, certain section of line outage can not be fast
Speed perceives, and the present situation of fast positioning failure, proposes the solution that a kind of software and hardware is combined.
The technical scheme is that：
The present invention provides a kind of user's power-off event report method based on low-voltage power line bandwidth carrier, and this method includes
Following steps：
S1, networking step：Include super capacitor for each electric energy meter configuration bandwidth carrier child node module STA, the STA, be
Concentrator configures host node module CCO, and User Profile information under taiwan area is handed down to concentrator by main website by uplink communication channel,
After concentrator receives the archive information issued, first and CCO carries out archives synchronization, and archives are synchronously after success, and CCO is according to archive information
Networking is carried out to STA and configures mesh information, according to the routing relation between each STA and CCO, for each STA distribute timeslot number and
Level number；Its middle-level number is network structure level sequence number where present node, and timeslot number is the progress from small to large by the number of plies
Distribution, with node layer then according to random fashion distribution, and timeslot number is unique in same network；
S2, STA generation power failure report step：
S2-1：Electric energy meter is powered using AC220V/380V, and when power down occurs, STA power-fail detection circuits detect that voltage is different
Often, STA modules are powered using super capacitor；
S2-2：The mesh information generation power-off event that STA configures according to CCO reports frame, includes the timeslot number of present node
Corresponding bitmap set, and reported according to broadcast transmission time slot rule；(STA timeslot number be in a network it is unique,
And configured by CCO, therefore each STA can be represented with bitmap mode).
Further, this method is further comprising the steps of：
S3：The STA time-divisions compete conflict avoiding and report step：
S3-1：Time slot scale value S is set, using node according to timeslot number TnTime slot scale value, obtains present node on mould
Sending time slots td, td=t × (Tn%S)；Wherein, t is that node sends interval；Present node delay tdSent after time；
S3-2：Present node detects the signal intensity in the external world when sending time slots arrive, and no signal then carries out reporting frame
Send, if other nodes are being sent, then the current time slots for keeping out of the way next round are transmitted；
S3-3：Neighbours STA is received after power-off event reports frame, is reported using power failure is carried out the step of step S3-1,3-2
Frame is sent.
Further, time slot scale value S is 64.
Further, this method is further comprising the steps of：
The step of S4, CCO processing have a power failure：
S4-1：CCO is received after power-off event reports frame, waits the certain time-delay time, and merge and collect；
S4-2：After delay time reaches, after no node reports, message bit pattern is converted into meter address and power-off event
Information reporting is to concentrator.
Further, delay time is 3 × 64t.
Further, this method is further comprising the steps of：
S5, concentrator processing power-off event step：
S5-1：Concentrator confirms to reported data, if not confirming, host node module will retry 3 times；
S5-2：Concentrator is organized into uplink communication message, reports main website according to the ammeter information reported.
Beneficial effects of the present invention：
The present invention uses bandwidth carrier, and frequency is up to 12MHz, and when STA ends have a power failure, STA is supplied using charging capacitor
Electricity, outage information reported event can be generated, is transmitted from power line.Broadband carrier signal is high-frequency signal, can be passed through
Coupled modes, signal electric side is transferred to from power failure side, has realized the information transfer of STA power-off events.
The method that user's power-off event of the invention based on low-voltage power line bandwidth carrier reports, can timely it find existing
The generation of user's power-off event, solve well power-off event report, positioning problems the problems such as, facilitate operation maintenance personnel timely
Investigation processing, improve accuracy, promptness that live power-off fault is safeguarded.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
Brief description of the drawings
Exemplary embodiment of the invention is described in more detail in conjunction with the accompanying drawings, it is of the invention above-mentioned and its
