There are two main policies for a kind of distribution main website data acquisition link automatic equalization management method, carry out two different
Automatic control and adjustment function.
Acquisition strategies in area.Acquisition strategies are a according to the configuration number and telecommunication terminal of acquisition server in area in area
Number, the number of automatic equalization distribution acquisition server connection terminal, without intervening manually.
In order to which communication terminal and entire gatherer process are managed and are monitored, the concept of link group is introduced.At this
In invention, 100 channel ends are divided into a link group, initialization distribution is carried out as unit of link group.If total number of channels
For C, then the link group sum N of required design can be represented with formula below：
N=[C/100]+1
Wherein [C/100] expression takes channel end sum divided by 100 integer part, can also use INT [C/100] table
Show.It is illustrated below with specific example：
450 channels are accessed in some acquisition zone, which is configured using two-shipper and initial configuration.According to upper
The formula stated, which can calculate, needs 5 link groups.Since 100 channels are 1 link group, following draw can be carried out
Point：
No.1-No.100, link group 1, No.101-No.200, link group 2, link group 1,2 is in A machines；
No.201-No.300, link group 3, No.301-No.400, link group 4, No.401-No.450, link group 5, chain
Road group 3,4,5, in B machines；
If the pattern that the acquisition zone is configured using multimachine, following division can be carried out according to identical principle：
No.1-No.100, link group 1, No.101-No.200, link group 2, and so on；
The present invention saves the investment of standby server by the way of acquisition zone server each other standby machine.According to
Concrete condition, two-server switch operating in section are active and standby each other.Due to previous active and standby service acquisition switching excessively frequency
It is numerous, the unstable of system can be caused.Therefore the present invention has made following modification, is described with reference to the drawings：
As shown in Figure 1 and Figure 2, after link down, former acquisition server A reconnects communication terminal automatically, if connection is lost
It loses, there will be the silence period of 5~20 seconds, later re-attached 3 times；
After acquisition server A reconnections fail three times, then switching signal can be sent to acquisition server B, notify server B
The connection of communication terminal is carried out, similarly when server B connection failure, the silence period of 5~20 seconds is also had, weighs again later
It is new to connect 3 times；
It is same as described above to send switching signal to acquisition server A after acquisition server B 3 failures of reconnection, it is logical
Know that acquisition server A carries out the connection of communication terminal, if acquisition server A connection failures, equally have the silence of 5~20 seconds
Time, later re-attached 3 times；
Such iterative cycles switching connection, until connecting normal.In the present embodiment, the silence period is 20 seconds.
The spare strategy in section：
As shown in Figure 3, Figure 4, in daily acquisition management work, it sometimes appear that some failures.Such as some acquisition
Area (acquisition zone) exchange fault causes the acquisition all acquisition servers in I areas to cannot connect to corresponding terminal；Or due to
Power supply class failure, such as power-off etc. suddenly cause to acquire all acquisition servers in I areas and delay machine；The present invention is done for such case
Following design：
The SCADA servers meeting online rate of periodic statistical terminal, if the online rate of terminal is 0 in an acquisition zone, and keeps
20~60 minutes, SCADA servers can send the signal of taking over fault area channel to other acquisition servers；Other normal works
Acquisition zone can balancedly undertake the collecting work of the fault collection area (Ith area of acquisition) channel signal.
The present invention using 100 channels as 1 link group, by other acquisition zones taken orally by all link groups in fault collection area
Business device is alternately taken over；Whole balancing link load.Specific share out the work is illustrated by the example below：
Certain region is equipped with 3 acquisition zones, and IIth area of acquisition and IIIth area of acquisition share 5 acquisition servers, and acquisition I areas access altogether
450 channels.Acquisition I areas due to exchange fault cause acquire all acquisition servers in I areas cannot connect to counterpart terminal or
Person causes in acquisition zone all acquisition servers to be delayed machine due to powering off suddenly.SCADA server statistics are to the end in the acquisition zone
Hold online rate be more than more than 30 minutes all for 0, therefore to IIth area of acquisition and acquire IIIth area and send to take over and acquire I area's channel signal
Work.
Since acquisition I areas access 450 channels altogether, it can be calculated according to formula and share 5 link groups.Because outside area
5 acquisition servers are shared, then acquisition server will increase a link group newly outside each area, balancedly undertake acquisition I areas
Channel signal collecting work.In the present invention if entire acquisition system only remains next acquisition zone that can be worked normally,
Under this extreme case, which can undertake the acquisition tasks of all communication terminals.
The method of the present invention mainly carries out distribution main website data acquisition link using the spare two kinds of strategies of acquisition in area and section
Road automatic equalization management work.It is acquired in area, load configuration equilibrium causes whole system reliability higher, farthest utilizes
Hardware resource.The present invention avoids in a manner that section acquisition server is active and standby each other and reconfigures standby server
Operation, saves the investment of standby server.The system maintenance simultaneously is convenient, the fully automated operation of policy service, not manually
Channel is reconfigured, is avoided due to a series of problems caused by manual operation so that system can safely and efficiently be run.
