Specifically, server obtains the scale parameter of the substation in operation of power networks parameter, is joined according to the scale of the substation Number accordingly determines the group number of the motion pick group, the steady control acquisition group or the PMU acquisitions group.Such as, server is according to son The scale parameter stood, the motion pick group can be divided into 1 group of motion pick, 2 groups of motion pick ..., motion pick L groups； The steady control acquisition group can be divided into steady 1 group of control acquisition, steady 2 groups of control acquisition ..., steady control acquisition H groups；The PMU can be adopted Collection group be divided into PMU acquire 1 group, PMU acquire 2 groups ..., PMU acquisition K groups；Wherein, described L, H, K are positive integer.Here, The scale parameter of the substation is that the number of the substation acquired by main website is needed in automation system for the power network dispatching.Here, according to The scale parameter of substation, to the determination of the group number of motion pick group, steady control acquisition group or PMU acquisition groups can according to it is described it is normal before The number of the substation of number of nodes and collected data is set to determine.For example, having 8 preposition nodes, respectively No. 1 in main website Machine~No. 8 machine, wherein the stipulations that IEC103 is configured on the acquisition channel of No. 3 machine~No. 5 machine distribution operations are realized to substation The data such as protection signal acquisition, therefore, No. 3 machine~No. 5 machines are then determined as surely controlling acquisition group；And the collected protection letter Number the substations of data have 3000, number 1-3000, then No. 3 machines can be divided into steady 1 group of control acquisition, to realize to 1- No. 4 machines are divided into steady 2 groups of control acquisition, to realize to 1001-2000 by the acquisition of the data of the protection signal of 1000 substations etc. No. 5 machines are divided into steady 3 groups of control acquisition, to realize to 2001-3000 son by the acquisition of the data of the protection signal of a substation etc. The acquisition of the data of the protection signal stood etc..Therefore, you can according to the quantity of preposition node (3, be No. 3 machine~No. 5 machines) and The size (1-3000 substation) of substation scale is realized is divided into steady control acquisition 1 group (No. 3 machines), steady control acquisition 2 to surely controlling acquisition group Group (No. 4 machines), steady control acquisition 3 groups (No. 5 machines).In this way, then realize the size according to substation scale, the existing grouping the case where Under to surely controlling the further refinement of acquisition group.

In the above-described embodiments, preposition node in main website is divided into motion pick group, steady control acquisition group or PMU and adopted by server Collection group realizes the division of each grab type of preposition node；Further, according to the scale of substation, and movement can be adopted Collection group, steady control acquisition group or PMU acquisition groups are divided into multiple groups, realize to preposition node further by point of grab type Group refinement.Wherein, server is by being grouped preposition node in main website according to operation of power networks parameter, every group of class after grouping The preposition node of type all has independently operated mode, and each preposition node also all has an independently operated mode in every group, group with Between group, individually between preposition node and preposition node, parallel form gathered data is all used, is not interfere with each other.

Step 103, the acquisition channel quantity of the quantity and needs of the normal preposition node for including is determined in each grouping.

Specifically, server determines in each grouping the acquisition channel of the quantity and needs for the normal preposition node for including Quantity.Here, the normal preposition node refers to the energy Real-time Feedback operation when the task for acquiring specified substation data The preposition node of status information and communication network status information；The acquisition channel quantity of the needs is that can realize that acquisition is specified Substation data required by task want acquisition channel sum.

Step 105, according to the quantity of the normal preposition node and the acquisition channel quantity, to the institute in the grouping State the acquisition channel that corresponding number is respectively configured in normal preposition node.

Specifically, quantity and the acquisition channel quantity of the server according to the normal preposition node, to the grouping The acquisition channel of corresponding number is respectively configured in the interior normal preposition node.Acquisition channel quantity to be configured in each grouping is The determination according to the quantity of the normal preposition node in each grouping and required acquisition channel quantity, therefore acquisition channel Configuration can according to the variation of the quantity and acquisition channel quantity of normal preposition node dynamic configuration, avoid actual moving process The acquisition channel of middle acquisition substation data concentrates on individual preposition nodes and causes the overload of the preposition node.

Further, normal preposition node is respectively configured pair according to the quantity of normal preposition node and acquisition channel quantity When answering the acquisition channel of number, acquisition corresponding with the normally preposition node can be determined respectively according to the configuration rule of setting Number of channels, the configuration rule by the setting are the balanced acquisition channel number of the normal preposition node configuration.One In a optional embodiment, the step 105 specifically includes：

When the quantity of normal preposition node is M, acquisition channel quantity is N number of, wherein described N, M are positive integer；

Referring to Fig. 3, wherein respectively with the quantity of normal preposition node for 4, the quantity of acquisition channel is 96~98 For altogether schematic example go out four kinds of situations.The first situation, normal preposition node is 4 in the grouping, acquisition channel quantity It is 96, acquisition channel quantity divided by normal preposition number of nodes aliquot (i.e. 96/4=24 is integer), then to each normal Preposition node all configures 24 acquisition channels.Normal preposition node is 4 in being grouped described in the second situation, acquisition channel quantity It it is 97, acquisition channel quantity divided by normal preposition number of nodes are aliquant (i.e. 97/4=24 ... 1), then to the wherein the 1st A normal preposition [97/4]+1=25 acquisition channels of node configuration, to other 3 normal preposition nodes all configure [97/4]= 24 acquisition channels, meeting the acquisition channel sum is：25+24 × 3=97.The third situation is normal in the grouping Preposition node is 4, and acquisition channel quantity is 98, and acquisition channel quantity divided by normal preposition number of nodes are aliquant (i.e. 98/4=24 ... 2), then to first 2 normal preposition nodes configures [98/4]+1=25 acquisition channels, to other 2 just Normal preposition node all configures [98/4]=24 acquisition channel, and meeting the acquisition channel sum is：25 × 2+24 × 2=98 It is a.4th kind of situation, normal preposition node is 4 in the grouping, and acquisition channel quantity is 98, acquisition channel quantity divided by Normal preposition number of nodes is aliquant (i.e. 98/4=24 ... 2), then all configures [98/4] to the 2 normal preposition nodes in centre Other 2 normal preposition nodes are all configured [98/4]=24 acquisition channel, meet the acquisition by+1=25 acquisition channels Total number of channels is：25 × 2+24 × 2=98.

It should be noted that when the quantity of normal preposition node and acquisition channel is the second situation, can arbitrarily select Wherein 1 normal preposition node configuration 1 acquisition channel more than other normal preposition nodes is taken, each normal preposition node institute is met The sum of the acquisition channel configured in the equilibrium to the full extent of the acquisition channel quantity of configuration and all normal preposition nodes is needs The acquisition channel sum of configuration；It, can be with when the quantity of normal preposition node and acquisition channel is third, the 4th kind of situation It is arbitrary to choose wherein 2 normal preposition nodes configuration 1 acquisition channel more than other normal preposition nodes, meet it is all it is normal before It is the acquisition channel sum needed to configure to set the sum of acquisition channel configured on node；And so on, for other required Acquisition channel divided by the aliquant situation of normal preposition number of nodes can arbitrarily choose wherein arbitrary several normal preposition nodes Configuration 1 acquisition channel more than other normal preposition nodes, meets the sum of the acquisition channel configured on the normal preposition node For the acquisition channel sum needed to configure.

According to the configuration rule of above-mentioned setting, may be implemented to be the normal preposition node in the grouping of each grab type Balanced acquisition channel number is configured, in this way, it is negative to ensure that acquisition channel is run in every group on the normal preposition node Harmony is carried, the operation that all acquisition channels concentrate on one or more preposition nodes is avoided and leads to these preposition nodes Overload the case where.

Step 107, the acquisition channel configured by the preposition node in the grouping is to the substation into line number According to acquisition.

Specifically, after main website starts, acquisition channel that the normal preposition node in the grouping is configured this just After being run on normal preposition node, attempts to connect with substation foundation, under normal circumstances, be communicated with substation normally, to described Substation carries out data acquisition.

In another optional embodiment, the step 105 further includes：

The priority index that the acquisition channel is run on the normal preposition node is set, wherein acquires same number According to priority index of the acquisition channel on the different normal preposition nodes it is different；It is according to the acquisition channel No the case where capable of running, determines that the relatively higher acquisition of the priority index that can be run on the different preposition nodes is logical Road is specified acquisition channel；

The step 107 further includes：The specified acquisition configured by the normal preposition node in the grouping is logical Road carries out data acquisition to the substation.

Here, the priority index indicates to acquire the acquisition channels of same data different described normal preposition The permission of resource is obtained on node, optimal acquisition access authorization for resource is highest priority, and worst acquisition access authorization for resource is minimum preferential Grade.The acquisition channel for acquiring same data refers to that substation data type is obtained on same preposition node in same packets is identical Multiple acquisition channels, the acquisition channels of the same data of the acquisition serial number on same preposition node usually and differs, such as Shown in Fig. 4, acquisition channel 1-5 is that acquisition channel, the acquisition channel 6-10 of the 1st data type of acquisition are the 2nd data type of acquisition Acquisition channel, acquisition channel 11-15 be acquire the 3rd data type acquisition channel, acquisition channel 16-20 be acquisition the 4th number According to the acquisition channel of type.Priority index can specifically use number, letter or the character representation to sort according to certain rule, By taking number as an example, priority index is smaller, then priority is higher, and priority index is bigger, then priority is lower.

The series of priority index is usually identical as the normal quantity of preposition node, and such as normal preposition node has M, then sets Shared M grade of the priority index is set, and is arranged and acquires the acquisition channels of same data different described normally preposition Priority index on node is different.Such as, normal preposition node be respectively the 1st, the 2nd, the 3rd ..., m-th；Preferentially Grade index be respectively：1st priority, the 2nd priority, the 3rd priority ..., M priority, wherein the M be positive integer； Wherein, the priority level of priority index is：1st priority>2nd priority>3rd priority>……>M priority；Acquisition Multiple acquisition channels (such as acquisition channel 1-5) of same data are distributed respectively the M normal preposition node (No. 1 machine~No. 4 Machine) on, and acquisition channel (such as acquisition channel of the same data of acquisition on any one (such as No. 1 machine) normal preposition node Priority index (for the 1st priority) 1-5) and adopting on other arbitrary normal preposition nodes (such as No. 2 machine~No. 4 machines) Collecting the priority index of the acquisition channel (such as acquisition channel 1-5) of same data, (the corresponding priority index on No. 2 machines is the 2 priority, the corresponding priority index on No. 3 machines are the 3rd priority, the corresponding priority index on No. 4 machines is the 4th excellent First grade) it is all different.

It should be noted that here, setting acquires the acquisition channels of same data different described normal preposition Further include the acquisition channel of setting acquisition different data (such as acquisition the under the premise of priority index difference on node The acquisition channel 1-5 of one data type, the acquisition channel 6-10 for acquiring the second data type) in same normal preposition node (such as 1 Number machine) on priority index differ (priority index that such as acquisition channel 1-5 corresponds on No. 1 machine be the 1st priority, Priority index on corresponding No. 1 machine of acquisition channel 6-10 is the 4th priority).

It is specifically schematically illustrated with reference to Fig. 4, Fig. 4 is specifically with the quantity of normal preposition node for 4, each For the quantity of acquisition channel on normal preposition node is 5, normal preposition node be respectively No. 1 machine, No. 2 machines, No. 3 machines and No. 4 machines, acquisition channel 1-5 are that acquisition channel, the acquisition channel 6-10 of the 1st data type of acquisition are the 2nd data type of acquisition Acquisition channel, acquisition channel 11-15 are that acquisition channel, the acquisition channel 16-20 of the 3rd data type of acquisition are the 4th data of acquisition The acquisition channel of type.Wherein, priority of the setting acquisition channel 1-5 on No. 1 machine be the 1st priority, it is excellent on No. 2 machines First grade is the 2nd priority, the priority on No. 3 machines is the 3rd priority, the priority on No. 4 machines is the 4th priority, i.e., Provided with acquire the acquisition channels (i.e. acquisition channel 1-5) of same data on the different normally preposition nodes (i.e. No. 1 machine~ No. 4 machines) priority index be different；Wherein, priority of the setting acquisition channel 1-5 on No. 1 machine be the 1st priority, It is the 3rd that priority of the acquisition channel 6-10 on No. 1 machine, which is the priority of the 4th priority, acquisition channel 11-15 on No. 1 machine, Priority, priority of the acquisition channel 16-20 on No. 1 machine are the 2nd priority, that is, the acquisition for being provided with acquisition different data is logical Road (i.e. acquisition channel 1-5, acquisition channel 6-10, acquisition channel 11-15, acquisition channel 16-20) is in same normal preposition node The priority index of (i.e. No. 1 machine) is also different.Be arranged such the acquisition channel run on the normal preposition node it is excellent First grade index may be implemented the load balancing configuration of the acquisition channel on the normal preposition node, reach preposition section in main website The equilibrium that acquisition channel is distributed on point, to realize the load balancing of advance data acquisition.

Here, the case where whether capable of being run according to the acquisition channel, determining can transport on the different preposition nodes The relatively higher acquisition channel of capable priority index is specified acquisition channel, is specifically included：

The preposition node of the 1st priority is respectively configured for each acquisition channel；If the acquisition channel can be in the configuration the 1st It is run on the preposition node of priority, then the acquisition channel is the specified acquisition channel of the preposition node of the 1st priority；

When the acquisition channel configured on the preposition node of the 1st priority cannot be run, then by the acquisition channel It is transferred on the preposition node of the 2nd priority and runs；If the acquisition channel can be in the preposition section of the 2nd priority of the configuration It is run on point, then the acquisition channel is the specified acquisition channel of the preposition node of the 2nd priority；

When the acquisition channel configured on the preposition node of the 2nd priority cannot be run, then by the acquisition channel It is transferred on the preposition node of the 3rd priority and runs；If the acquisition channel can be in the preposition section of the 3rd priority of the configuration It is run on point, then the acquisition channel is the specified acquisition channel of the preposition node of the 3rd priority；

And so on；Until, when the acquisition channel configured on the preposition node of the M-1 priority cannot be run, Then the acquisition channel is transferred on the preposition node of M priority and is run；If the acquisition channel can be in the M configured It is run on the preposition node of priority, then the acquisition channel is the specified acquisition channel of the preposition node of the M priority.

In an alternative embodiment, incorporated by reference to reference to Fig. 4 and Fig. 5, whether can be transported according to the acquisition channel to described Capable situation determines that the relatively higher acquisition channel of the priority index that can be run on the different preposition nodes is specified adopts Collection channel is further explained explanation, and specifically with the quantity of normal preposition node for 4, acquisition channel is 5 (i.e. acquisition channels For 1-5), as shown in figure 4, normal preposition node is respectively No. 1 machine, No. 2 machines, No. 3 machines and No. 4 machines, acquisition channel 1-5 is 1 The priority that the priority configured on number machine is all the 1st priority, is configured on No. 2 machines is all the 2nd priority, on No. 3 machines The priority of configuration is all the 3rd priority, and the priority configured on No. 4 machines is all the 4th priority.At this point, working as acquisition channel After 1-5 is enabled, all option and installment runs (being run on the preposition node for being configured to highest priority) on No. 1 machine.At No. 1 On machine, acquisition channel 1-5 is attempted to establish with substation and be connected, wherein is connected, is then adopted assuming that acquisition channel 1-3 can be established with substation Collection channel 1-3, which is just fixed on No. 1 machine, to be run, gathered data；Assuming that acquisition channel 4 and acquisition channel 5 are within the preset time It can not be connect with substation namely acquisition channel 4 and acquisition channel 5 cannot be run on the preposition node of highest priority, then will Acquisition channel 4 and acquisition channel 5 are transferred on the preposition node of time high priority (the second priority), i.e. are run on No. 2 machines. On No. 2 machines, the acquisition channel 4 and acquisition channel 5 that are transferred are attempted to establish with substation and be connected, it is assumed that acquisition channel 4 can be with Connection is established in substation, then acquisition channel 4 is just fixed on No. 2 machines and runs, gathered data；And acquisition channel 5 is in the preset time It inside can not still establish and connect with substation, then be transferred to acquisition channel 5 on the preposition node of time high priority (third priority), That is it is run on No. 3 machines.On No. 3 machines, the acquisition channel 5 being transferred is attempted to establish connection with substation, it is assumed that acquisition channel 5 at this time It can not still establish and connect with substation within the preset time, then acquisition channel 5 being transferred to time high priority, (the 4th is preferential Grade) preposition node on, i.e. run on No. 4 machines.On No. 4 machines, acquisition channel 5 can be established with substation and be connected, then acquisition channel 5 Just it is fixed on No. 4 machines and runs.Finally, the case where whether capable of being run according to the acquisition channel, it is determined that can on No. 1 machine The acquisition channel 1-3 for running highest priority index (i.e. the 1st priority) is specified acquisition channel, can be run on No. 2 machines The acquisition channel 4 of secondary high priority index (the 2nd priority) is specified acquisition channel, and what can be run on No. 4 machines is minimum preferential The acquisition channel 5 of grade index (the 4th priority) is specified acquisition channel.Whether can according to the acquisition channel in this way, realizing The case where enough running determines that the relatively higher acquisition channel of the priority that can be run on the preposition node is specified acquisition Channel.

Here, it the case where whether server can run according to the acquisition channel, determines different described preposition After the relatively higher acquisition channel of the priority index that can be run on node is specified acquisition channel, server passes through described point The specified acquisition channel that normal preposition node in group is configured realizes the acquisition that data are carried out to substation.

It should be noted that if a certain acquisition channel is in the preposition node for being transferred to lowest priority in the grouping It is still that can not establish to connect with substation within the preset time, then it is logical to be determined as fault collection for the acquisition channel when upper operation Road cannot then be run in grouping on any normal preposition node.For example, in one alternate embodiment, please joining again Fig. 5 is read, if acquisition channel 5 is transferred on No. 4 machines, in preset time, still can not establish and connect with substation, then acquire Channel 5 cannot be run in No. 1 machine, No. 2 machines, No. 3 machines, No. 4 machines on any one normal preposition node, at this time acquisition channel 5 It is determined as fault collection channel.

In this way, setting acquires priority of the acquisition channel of same data on the different normal preposition nodes Difference can make each acquisition channel campaign for out the highest normal preposition node of acquisition access authorization for resource, to it is described it is normal before It sets and is run on node, the data of acquisition substation；Secondly, according to that whether can be run to acquisition channel the case where, determines not With the relatively higher acquisition channel of the priority index that can be run on the preposition node be specified acquisition channel it is specified logical In fact road realizes the dynamic adjustment of the specified acquisition channel operating condition configured on the normal preposition node, i.e., The dynamic configuration of load balancing on the normal preposition node is showed.

It is that can not establish to connect with substation within the preset time with acquisition channel it should be noted that in above-described embodiment When connecing, then it is transferred on the preposition node that priority is relatively high in other preposition nodes, in other optional embodiments In, it can also be when some or the certain acquisition channels on the normal preposition node be disconnected or are frequently interrupted for a long time, then By this, some or certain acquisition channels are transferred on the preposition node that priority is relatively high in other preposition nodes, transfer Implementing step can be same as above, to realize on the normal preposition node can running priority grade index it is relatively higher Acquisition channel；And realize the dynamic adjustment of the acquisition channel operating condition on the normal preposition node, realize institute State the dynamic configuration of load balancing on normal preposition node.

In another embodiment, described the case where whether capable of being run according to the acquisition channel, different institutes is determined It is to further include before specifying acquisition channel to state the relatively higher acquisition channel of the index that can be run on preposition node：

Here, the impartial distribution principle refers to when the acquisition channel that will be increased newly is configured to normal preposition node with maximum Degree can ensure that the acquisition channel quantity run on each normal preposition node tends to equal principle.Such as the number of preposition node Amount is 4 (No. 1 machine~No. 4 machines), and before not newly-increased acquisition channel, the acquisition channel number run on No. 1 machine is most, No. 2 machines Upper operation acquisition channel for several times it, third, the acquisition channel number run on No. 4 machines is most for the acquisition channel number run on No. 3 machines It is few, when newly-increased acquisition channel, the newly-increased acquisition channel will be set to configure the acquisition channel of the 1st priority on No. 1 machine Number is minimum, with configured on No. 2 machines the acquisition channel of the 1st priority for several times it, it is logical to configure the acquisition of the 1st priority on No. 3 machines Road number is third, most with the acquisition channel number for configuring the 1st priority on No. 4 machines, and finally so that on four preposition nodes The impartial distribution principle that acquisition channel quantity utmostly tends to be equal is allocated.

In an alternative embodiment, referring to Fig. 6, be further explained explanation to the impartial principle distribution, specifically with For the quantity of normal preposition node is 4, normal preposition node is respectively No. 1 machine, No. 2 machines, No. 3 machines and No. 4 machines.

Before newly-increased acquisition channel, acquisition channel 34 is shared, wherein priority of 10 acquisition channels on No. 1 machine Index is the 1st priority, and 10 acquisition channels can be established with substation on No. 1 machine and be connected；Wherein 9 acquisition channels Priority on No. 2 machines is the 1st priority, and 9 acquisition channels can be established with substation on No. 2 machines and be connected；Its In priority index of 8 acquisition channels on No. 3 machines be the 1st priority, and 8 acquisition channels can be on No. 3 machines It establishes and connects with substation；Priority of wherein 7 acquisition channels on No. 4 machines is the 1st priority, and 7 acquisition channels It can establish and connect with substation on No. 4 machines.When increasing 10 acquisition channels newly, server is according on current normal preposition node The case where acquisition channel can be run on the priority case and the normal preposition node being configured, (i.e. at present just The 1st priority acquisition channel distribution number is 10 on No. 1 machine of normal preposition node and 10 acquisition channels can be on No. 1 machine Operation, on No. 2 machines the 1st priority acquisition channel distribution number be 9 and 9 acquisition channels can be run on No. 2 machines, No. 3 The 1st priority acquisition channel distribution number is 8 on machine and 8 acquisition channels can be run on No. 3 machines, the 1st on No. 4 machines The case where priority acquisition channel distribution number is 7 and 7 acquisition channels can be run on No. 1 machine), newly-increased is adopted Collect channel, is distributed on the normal preposition node to each grouping according to impartial distribution principle.Due at this time in No. 1 machine The acquisition channel of upper operation is most, and the acquisition channel run on No. 2 machines takes second place, and the acquisition channel run on No. 3 machines is again It, the acquisition channel run on No. 4 machines is minimum, and therefore, 10 newly-increased acquisition channels are configured on No. 4 machines at most (i.e. 4 acquisition channels) take second place (i.e. 3 acquisition channels), third (i.e. 2 acquisition channels), 1 on No. 2 machines on No. 3 machines On number machine minimum (i.e. 1 acquisition channel) so that the newly-increased acquisition channel configure to No. 1 machine~No. 4 machine after utmostly It can ensure that the acquisition channel quantity run on each normal preposition node tends to be equal.

It should be noted that since the acquisition that the preposition node selects the priority index that can be run relatively higher is logical Road is specified acquisition channel, therefore, after newly-increased acquisition channel is configured to normal preposition node, the newly-increased acquisition can be arranged The priority index in channel is the 1st priority, i.e. 10 newly-increased acquisition channels on the normal preposition node of the configuration The 1st priority distribution number on No. 1 machine have 1, the 1st priority on No. 2 machines distribution number have 2, the on No. 3 machines 1 priority distribution number has 3, the 1st priority distribution number has 4 on No. 4 machines.

In this way, after may be implemented in newly-increased acquisition channel, acquisition channel is all on the normal preposition node of the 1st priority In the case of capable of being connect with substation, utmostly can when realization configures newly-increased acquisition channel to normal preposition node It is enough to ensure that the acquisition channel quantity run on each normal preposition node tends to equal principle, in this way, realizing each acquisition Configuration and operation of the channel in the dynamic load leveling of the normal preposition node.

In an alternative embodiment, as shown in fig. 7, before step 105, further include：

Step 104, detect whether each grouping has newly-increased normal preposition node and/or whether have normal preposition node It breaks down；There is any normal preposition node when having in any grouping in newly-increased normal preposition node or each grouping When failure, according to the normal preposition section to break down in the quantity of the newly-increased normal preposition node or each grouping The quantity of point redefines the acquisition channel number of the normal preposition number of nodes and the needs that include in each grouping Amount.

Specifically, server detect each grouping whether have newly-increased normal preposition node and/or whether have it is normal before Node failure is set, here, it includes when the preposition node to break down that whether the grouping, which has newly-increased normal preposition node, Revert to normal preposition node；Here, whether each grouping of the detection has the normal preposition node failure to be：Server The normal preposition node is detected in real time whether there is running state information and communication network status information, if it is present For normal preposition node, if being not present, for the preposition node of failure；It is newly-increased whether each grouping of detection has Normally preposition node is：Server detects the preposition node of failure in real time, if the preposition node to break down has operation Status information and communication network status information, then for the preposition node of the failure restore again normally, be judged as it is newly-increased just Increase preposition node in normal preposition node or main website newly, it is described to increase preposition node energy Real-time Feedback running state information newly and lead to Communication network status information；When have in any grouping in newly-increased normal preposition node or each grouping have it is any it is normal before It is normal according to breaking down in the quantity of the newly-increased normal preposition node or each grouping when setting node failure The quantity of preposition node redefines the acquisition of the normal preposition number of nodes and the needs that include in each grouping Number of channels.Here, the acquisition of the normal preposition number of nodes and the needs that include in each grouping is redefined After number of channels, determine that the normal preposition node corresponds to number respectively in the grouping according to the configuration rule of setting again Acquisition channel.As shown in figure 8, specifically with the quantity of normal preposition node for 4, for acquisition channel is 96, before normal It is respectively No. 1 machine, No. 2 machines, No. 3 machines and No. 4 machines, under normal circumstances, each preposition node on this 4 preposition nodes to set node On will have 24 channel normal operations.At a certain moment of operation, No. 1 machine breaks down, and 24 run on No. 1 machine are adopted Collect channel, 3 preposition nodes that other normal operations are transferred to according to the configuration rule of setting (are respectively No. 2 machines, No. 3 machines, 4 Number machine) on run, i.e., each normal preposition node runs 32 acquisition channels on described 3 normal preposition nodes.In operation Another moment will be transferred to 3 of other normal operations before when the preposition node (No. 1 machine) broken down restores normal Acquisition channel on preposition node is restored to initial conditions, and here, the initial conditions refer to that this 4 preposition nodes are all normal When the case where operation, the acquisition channel number distribution condition that is run in the normal node.

Here, if preposition nodes break down, the acquisition channel run on the preposition node of the failure is shifted to set The configuration rule set is configured on the normal preposition node of normal operation, and the specific manifestation form of the configuration rule includes mainly such as Lower two kinds of situations：

First, it is M to redefine normal preposition number of nodes, and acquisition channel quantity is N number of, wherein described N, M are just Integer；If N/M aliquots, N/M acquisition channel is respectively configured to the normal preposition node in the grouping；If N/M is not [N/M]+1 or [N/M] a acquisition channel is respectively configured to the preposition node in the grouping, before the M normal in aliquot The acquisition channel quantity summation for setting node configuration is N number of.In embodiment as shown in Figure 8, it is assumed that No. 1 machine breaks down, then weighs New to determine that the quantity of normal preposition node is 3 (No. 2 machines, No. 3 machines and No. 4 machines), acquisition channel is 96, then No. 2 machines, No. 3 96/3=32 acquisition channel is all run on machine and No. 4 machines.

Second, determine that the acquisition channel run on the preposition node to break down is that N ' is a, normal preposition number of nodes is M It is a, wherein the N ', M are positive integer；If N '/M aliquots, the preposition node in the grouping is matched again respectively again Set N '/M acquisition channel；If N '/M is aliquant, to the preposition node in the grouping again respectively be reconfigured [N '/M]+ The acquisition channel quantity summations of 1 or [N '/M] a acquisition channel, the M normal preposition nodes configurations are that N ' is a.As shown in Figure 8 Embodiment in, it is assumed that No. 1 machine breaks down, it is determined that the acquisition channel run on No. 1 machine of failure be 24, normally Preposition number of nodes is 3 (No. 2 machines, No. 3 machines and No. 4 machines), then is all running 24 originally on No. 2 machines, No. 3 machines and No. 4 machines On the basis of acquisition channel, rerun 24/3=8 acquisition channel, runs 32 acquisition channels in total.

It should be noted that after being based on above-mentioned configuration rule to preposition nodes break down, normal preposition section is reconfigured The acquisition channel number run on point can realize that load balancing configures, the acquisition run on obtained normal preposition node The result of channel number is consistent.Wherein, for the second situation, due to need not all distribute acquisition channel again, i.e., The acquisition channel that need not have been run to the preposition node not broken down is redistributed, and only needs to redistribute to going out Acquisition channel on the preposition node of existing failure is redistributed, so as to be further reduced the work of load balancing configuration Amount, improves the efficiency of system.
