Description
Technical field
The present invention relates to the communication monitoring of power distribution automation, particularly a kind of power distribution automation wireless public network communication system
State monitoring method.
Background technology
Power distribution automation refers to based on a rack and equipment, comprehensive utilization computer, information and communication technology,
And by the information integration of related system, realize the monitoring to power distribution network, control and fast failure isolation.
Occupy critical role in electrical network especially Distribution Automation Construction, be a kind of requisite communication mode.As
Need to using wireless public network communication, distribution terminal typically can an integrated Wireless Data Transmission Terminal (wireless data transmission terminal), built-in
Communication module and draw-in groove etc., can achieve the transmission of dialing data.
With the development of power distribution automation, electric company proposes requirements at the higher level to every operating index, to using wireless public affairs
The O＆M of the distribution terminal of Network Communication it is also proposed requirement.
The wireless public network communication of power distribution automation utilizes the public network of operator's (movement, UNICOM, telecommunications etc.), in public network
In build VPN VPN.But the communication of distribution power automation terminal and domestic consumer's call, online shared network money
Source.
When distribution power automation terminal adopts wireless public network to communicate, the trouble point existing is many.Therefore, wireless public network communication tool
The features such as have unstable, easy packet loss.Additionally, due to communication equipment all industrial site uses out of doors, it is understood that there may be various
Environmental disturbances, make Wireless Data Transmission Terminal or SIM there is certain fault rate, and once there is communication failure, only can be from joining
Recognize terminal Offtime at electric automation main station system, but specifically what reason can not obtain offline.Make one
To scene it is also desirable to by display lamp, pole-climbing and unlatching ring main unit cabinet door could observe that communication module status indicate.
It is similar at present and solves this problem and be to increase the wireless network management system of wireless communication module, referring in particular to shown in Fig. 1, no
Gauze guard system is long-range and wireless data transmission module is communicated, and when communication is online, can obtain sim card IP, operation conditions, flow
Deng essential state data.
But obtain the status data (as IP, flow, signal etc.) of wireless data transmission module by wireless network management system, for ensureing
Accuracy, need regularly in short-term and wireless data transmission module communicated, if by 1 minute once, 5M will be had more within one month
Left and right flow.Calculated with the mesh previous city wireless terminal amount of thousand of, will produce at least several outside normal traffic communication every year
Ten thousand yuan of expense, when scope is wider, then cost consumption is bigger.
Can only be communicated when wireless data transmission module is online by wireless network management system, when communication disconnects (as network
Or the reason such as SIM or deadlock), wireless network management system is to obtain the specific offline reason that communicates.Therefore wireless network management
System is more for ledger management, can provide for the O＆M of power distribution automation radio communication, the communication abnormality analysis of causes
Information very limited, be difficult to directly judge abnormal cause by these information.
If by communication abnormality logout it is necessary to write information into the flash of itself at any time in wireless data transmission module
In, if write in ram, when wireless data transmission module judges that communication is offline, need to be restarted by inherent logic, Suo Youxin
Breath will be lost, and read not out afterwards at all.But frequently read and write flash, will result in the damage of chip quickly.Accordingly, it would be desirable to one
Plant new solution.
