A kind of long-range retrieval method of warning information of power automatic system of the invention is deployed in superior system
One quantity Receiving Agent node, likewise, disposing the second quantity in lower system sends agent node and a master control
Node, superior system remotely have access to the warning information of lower system, specifically include following procedure:
Step S1, master control node in lower system to send carried out between agent node and Receiving Agent node it is one-to-one
Pairing link setup.
It carries out using balance load transmission model when warning information transmission between superior system and lower system, realize interdepartmental
Warning information of uniting transmits.Specific building process are as follows:
The first quantity Receiving Agent node and a master control node are disposed in superior system, this master control node is supervised in real time
Receiving Agent node survival condition is surveyed, the second quantity sends agent node and one total likewise, disposing in lower system
Node is controlled, master control node real-time monitoring sends agent node survival condition and carries out task distribution, master control to agent node is sent
Node can be deployed on any server of lower system.The numerical value of first quantity and the second quantity can be according to electric power certainly
Dynamicization system requirements are configured, and the numerical value of this setting is natural number.And the numerical value of the numerical value of the first quantity and the second quantity
Can be identical, it can also be different.
Above-mentioned master control monitoring nodes agent node survival condition specific implementation is main controlled node timing receipt agent node hair
The heartbeat sent then judges corresponding agent node failure when not receiving heartbeat in the time interval of setting.
When superior system needs remotely to have access to the warning information of lower system, the master control node of superior system first will be sent out
Message is sent to the master control node of lower system, how many Receiving Agent node in current superior system informed, lower system
Master control node will send agent node and Receiving Agent node carries out a pair according to the number of the Receiving Agent node of superior system
One pairing link setup, the link setup process are realized using Transmission Control Protocol.When upper and lower grade agent node number is inconsistent, of pairing
Number is limited to the less side of two sides agent node number.
Fig. 1 is one embodiment schematic diagram that superior system and lower system establish communication network.The superior system in this Fig. 1
In have 4 Receiving Agent nodes, be B1, B2, B3 and B4 respectively, have in lower system 4 transmission agent nodes and one it is total
Node is controlled, 4 transmission agent nodes are respectively A1, A2, A3 and A4.When superior system needs remotely to have access to the alarm of lower system
When information, the agent node number of this side is informed to the master control node of lower system by way of sending message first.Junior
The master control node of system will send agent node using Transmission Control Protocol and Receiving Agent node is matched link setup, Zong Gongpei one by one
It is A1-B1, A2-B2, A3-B3, A4-B4 respectively to 4 network transmission lines out, that is to say, that with this 4 network transmission lines
Realize the transmission of cross-system warning information.
Step S2, when superior system needs to have access to the warning information of lower system, superior system will need the announcement had access to
Alert type is sent to the master control node of lower system, and master control node is by all alarm type mean allocations to having matched each of link setup
Agent node is sent, makes each transmission agent node that the alarm type by distribution to itself only be needed to be sent to superior system.
It is exactly alarm type that every warning information, which has itself a attribute,.Master control node is by all alarm type average marks
All transmission agent nodes for having matched link setup of dispensing form alarm type and each corresponding relationship sent between agent node, and
Corresponding relationship between alarm type and each transmission agent node is stored in distributed memory storage system, in order to send
Agent node obtains in time.Distributed shared memory storage system, such as zookeeper in the prior art.
It is T1-T40 totally 40 seed type referring to the alarm type that in Fig. 1, superior system needs to have access to, has matched in lower system
There are 4 to the transmission agent node of link setup, T1-T40 is assigned to 4 transmission agent nodes, i.e. alarm type T1- by master control node
T10 distributes to A1, alarm type T11-T20 distributes to A2, alarm type T21-T30 distributes to A3, alarm type T31-T40 points
Dispensing A4, and alarm type and 4 are sent into the corresponding relationship between agent node and are stored in zookeeper distributed storage system
In system, so that 4 transmission agent nodes are read in time.
Send the Receiving Agent section that agent node only sends the warning information with these type matchings to superior system
Point, other types of alarm are abandoned, and the data volume to guarantee remote transmission is minimum.
Step S3, after lower system receives the warning information of multicast, each agent node that sends judges this warning information
Whether alarm type belongs to what itself was responsible for, this warning information is sent to Receiving Agent section corresponding thereto if belonging to
Point.
It is the transmission that point-to-multipoint is carried out in the form of multicast in an internal system warning information.Each agent node is from multicast
Warning information is obtained in message, then searches each sending node and alarm type inside zookeeper distributed memory system
Corresponding relationship, judge this warning information alarm type whether with distribution to itself be responsible for alarm type match, if
This warning information belongs to the responsible type of own node, then sends superior system by TCP or UDP for this warning information
Receiving Agent node.
Superior system has access to the troubleshooting in lower system in warning information transmission:
After master control node monitors a transmission agent node failure in lower system, by the control of master control node,
The warning information that the transmission agent node of failure is responsible for transmission is shared by other transmission agent node equilibriums that this side is survived.But
When being that other transmission agent nodes transmit the warning information newly shared, the opposite end Receiving Agent node of this part warning information is not
Become, to guarantee sufficient bandwidth usage and load balancing；
After transmission agent node failures multiple in lower system, the responsible alarm type of all malfunctioning nodes is by other surplus
Remaining surviving node equilibrium is shared；And the opposite end Receiving Agent node of this alarm type remains unchanged.
After a Receiving Agent node failure of superior system, transmission agent node corresponding with this malfunctioning node will
The balanced other remaining survival Receiving Agent nodes that are sent to of its responsible alarm type are received.Multiple Receiving Agent nodes
When failure, above-mentioned similar operation is also carried out, i.e. transmission agent node is other by being sent to for its responsible alarm type equilibrium
Residue survival agent node receives.
In 4 pairs of agent nodes shown in Fig. 2 (a), agent node A1 failure, the alarm type T1- that it is responsible for are sent
T10, which is averaged, to be assigned to other 3 transmissions agent nodes and is sent.Specific distribution is as shown, by alarm type T1-T4 points
Dispensing sends agent node A2, and T5-T7 distributes to A3, and T8-T10 distributes to A4.But the warning information of these T1-T10 types
Receiving Agent node is still Receiving Agent node B1.
In the case where sending agent node A1 failure in Fig. 2 (b), A2 also breaks down, then the alarm class that they are responsible for
Type T1-T20, which is averaged, to be assigned to remaining other 2 normal nodes and is sent.Specific distribution is as shown, A1 is responsible for
T1-T5 and A2 responsible T11-T15 distributes to A3, T6-T10 and T16-T20 and distributes to A4.But the warning information of these types
Receiving Agent node remains unchanged.
Fig. 3 is Receiving Agent node failure schematic diagram in the present invention.When the Receiving Agent node B1 failure of superior system,
It then sends agent node A1 to attempt to establish the link with other agent node B2-B4 of superior system, if link setup success, A1 will
Itself responsible T1-T10 alarm type sending a warning message to B2, B3, B4 node load balancing.The process of link re-establishment is not
Need the participation of master control node.
The data assurance punch-out equipment system of warning information transmission:
When a transmission agent node breaks down in lower system, master control node can be through before finding this node failure
Cross regular hour delay, the i.e. time interval of heartbeat judgement.Warning information multicast in this period not reproduce.Therefore exist
Third quantity backup node is set for each transmission agent node in lower system.The numerical value of third quantity can be according to electric power certainly
Dynamicization system requirements are configured, and value is natural number.Backup node is alternatively referred to as shadow node, and backup node itself is also
Agent node, the content of backup are that it corresponds to the warning information that host node issues in for a period of time.Host node refers to the announcement of backup
Transmission agent node belonging to alert information is original.This is a mutual standby host system, any one in lower system sends agency's section
Point be host node simultaneously and other agent nodes shadow node (backup node).Shadow node is responsible in addition to sending itself
Alarm data outside, also keep in memory itself correspond to host node multicast alarm data.Temporary data volume is sentenced for heartbeat
All multicast alarm information in disconnected time interval.
After host node failure, some shadow node that master control node can choose host node sends temporary data
To host node in the corresponding Receiving Agent node of superior system, to guarantee that data are not lost.
Each agent node that sends is provided with the data assurance case (i.e. shadow node) of several numbers as other transmission generations
Reason node temporarily saves warning information.The quantity of safety box depends on that how many other agent nodes of each agent node are slow for it
Deposit data.Assuming that a total of n agent node of lower system, then be up to n-1 other nodes are slow for some agent node
Deposit data.Each agent node has n-1 data safety box at this time, i.e., each node is other n-1 nodal cache numbers
According to.
Assuming that in system one heartbeat (heartbeat per second send primary) is not received in agent node 3 seconds, then judge this
A node failure.The data then cached in shadow node are exactly the warning information that 3 seconds internal fault agent nodes should forward, continue with
New information replaces old information.
Fig. 4 is data assurance case schematic diagram of mechanism in the present invention, and lower system sends the backup section of agent node A1 in figure
Point is A2, A3, A4, and the backup node of A2 is A1, A3, A4, and the backup node of A3 is A1, A2, A4, the backup node of A4 be A1,
A2, A3 after sending agent node A3 failure in figure, are sent the data in its backup node A3 by master control node selection node A1
To the Receiving Agent node B3 of opposite end.If multiple sending node failures select several nodes to issue it by master control node
The data of backup node, the principle of selection are not concentrate to be issued by a node, are postponed so larger.
Correspondingly, the present invention also provides a kind of warning information of power automatic system remotely to have access to equipment, feature
It is to be deployed with the first quantity Receiving Agent node in superior system, the second quantity is deployed in lower system and sends agency
Node, this deployed with devices is in lower system comprising pairing link setup module and alarm type distribution module；
