Description

Information interaction method, device and system between heterogeneous systems

Technical Field

The invention belongs to the field of power grid dispatching, and relates to a method, a device and a system for information interaction between heterogeneous systems.

Background

In the early design of internal and external systems of a power grid regulation center, most of the systems adopt a single architecture, the architecture can reduce the difficulty of system development and deployment, and each system adopts a technical architecture route of different message middleware. However, as the amount of traffic is continuously expanded and the number of systems is continuously increased, each system gradually forms an information isolated island, and interaction between the systems becomes extremely difficult. The existing solutions mainly have the following modes: a file or database based approach, a protocol message based approach, a unified platform based approach, and an ESB (Enterprise Service Bus) based approach.

The file or database-based mode is an effective mode for realizing information sharing among systems for a long time by sharing files or public databases, and the file sharing mode is simple and clear to realize. However, the method is only suitable for service scenes with slow information change, small single file size and low real-time requirement. Compared with a file mode, the database mode has the advantages of simpler and more flexible interaction and stronger expandability. However, this method is not highly real-time, is more suitable for information sharing of structured data, and is difficult to effectively support semi-structured data and unstructured data. The mode based on the protocol message can realize the sharing of certain information, and the systems of the two parties can realize the interaction of the information only by using corresponding protocol communication and message coding and decoding software modules without using additional hardware equipment. However, the data interaction range, the data types and the data capacity are limited by regulations, the expansion and maintenance cost of new functions and new data types is high, and the ever-increasing business information access and application function sharing requirements are difficult to support.

With the continuous improvement of the automation level of the power dispatching system, the conversion from the original service system independent construction mode to the construction of the unified support platform is gradually completed, and an interaction mode based on the unified platform is formed. However, a large number of service application systems still exist outside the scheduling control system, these systems often adopt different message buses and service frameworks, information is difficult to communicate among the systems, services are difficult to share, and the technical problem of getting through each service system is still not thoroughly solved. In an ESB (enterprise service bus) based approach, an enterprise service bus is an important means for building a service-oriented architecture, can support services, messages, and event-based interactions in heterogeneous environments, and has an appropriate service level and manageability. However, the essence of the method is that each business system carries out message communication and service calling by integrating a third-party protocol, the realization is complex, and the application and the function of the original system need to be adaptively modified.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or device that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or device.

The invention is described in further detail below with reference to the accompanying drawings:

referring to fig. 1, in an embodiment of the present invention, a method for information interaction between heterogeneous systems is provided to effectively solve the problem of a barrier to message communication and service invocation due to different architectures and different message middleware adopted between heterogeneous systems in a power grid control center.

Specifically, the information interaction method between heterogeneous systems may be applied to an information interaction system between heterogeneous systems, and referring to fig. 2, the heterogeneous cluster system includes a first heterogeneous system, a second heterogeneous system, and a message queue cluster; the first heterogeneous system and the second heterogeneous system are both in communication connection with the message queue cluster. The first heterogeneous system, the second heterogeneous system and the message queue cluster can be server clusters.

The first heterogeneous system and the second heterogeneous system are not limited to specific systems, but are only used for explaining two systems for information interaction, and the two systems for information interaction are shown to be heterogeneous. It should be noted that, for a practical system, when the information interaction method between heterogeneous systems according to the present invention is applied, it may be considered as a first heterogeneous system, and may also be considered as a second heterogeneous system.

In this embodiment, the first heterogeneous system generally includes a local queue cluster, a gateway, a database/cache, and a plurality of consumers; the second heterogeneous system generally comprises a local queue cluster, a gateway, a database/cache and a plurality of producers; wherein, a protocol adapter is arranged in the gateway. Both the consumer and the producer refer to members of a heterogeneous system and may be understood as a single server or as a single server unit integrated by several servers.

In this embodiment, the method for information interaction between heterogeneous systems includes the following steps:

s1: the first heterogeneous system acquires the communication message, converts the format of the communication message into a preset unified message format, acquires the communication message with the unified format and sends the communication message to the message queue cluster.

Specifically, when each consumer in the first heterogeneous system needs to perform communication message interaction with the second heterogeneous system, each consumer generates a communication message and concentrates the communication message on the local queue cluster of the first heterogeneous system, and stores the communication message in the database/cache, so that the communication message is acquired.

And then, transmitting the communication message to a gateway of the first heterogeneous system, converting the format of the communication message into a preset unified message format through a protocol adapter in the gateway to obtain a unified format communication message, and sending the unified format communication message to the message queue cluster through the gateway of the first heterogeneous system. The scheme is realized by directly adding the gateway in the existing first heterogeneous system and adding the corresponding protocol adapter in the gateway, no additional development work needs to be carried out on the existing first heterogeneous system, and the protocol adapter needs to be set according to the actual communication protocol of each heterogeneous system to realize the adaptation with the heterogeneous systems with different communication protocols.

Because the communication protocols between the heterogeneous systems are different, after the communication message of the first heterogeneous system is directly forwarded, the second heterogeneous system is difficult to analyze after being received, so that when the information interaction method between the heterogeneous systems is used for information interaction, the format of the communication message is firstly converted into a preset uniform message format, and the uniform message format is required to be defined in advance.

In a possible implementation, referring to fig. 3, the communication message is distributed in a message set, and the unified message format includes a plurality of messages, and each message includes a message offset unit, a message size unit, and a message unit, which are sequentially arranged. The value of the message offset unit is used for marking the offset of the current message in storage, the value of the message size unit is used for representing the size of the message, and the message unit is used for actually storing the message.

The message unit comprises a message length unit, a message timestamp unit, a message offset unit, a message main key length unit, a message main key unit, a message value length unit, a message value unit and a header information unit which are sequentially arranged. Referring to table 1, the values of the parts in the message unit are shown to represent:

table 1 message element format parsing table

The head information unit comprises a head information main key length unit, a head information main key unit, a head information value length unit, a head information value unit and a checking bit unit which are sequentially arranged. Specifically, the header information primary key length unit, the header information primary key unit, the header information value length unit, and the header information value unit may refer to the message primary key length unit, the message primary key unit, the message value length unit, and the message value unit, and only convert the corresponding content of the message into the corresponding content of the header message, and the value of the check bit unit is a content check code and ranges from the value of the message length unit to the value of the message value unit.

S2: and the second heterogeneous system receives the communication message with the uniform format sent by the message queue cluster and converts the format of the communication message with the uniform format into a communication format of the second heterogeneous system.

Specifically, the gateway of the second heterogeneous system receives the communication message with the uniform format sent by the message queue cluster, and then the communication message with the uniform format is converted into the communication format of the second heterogeneous system through a protocol adapter in the gateway of the second heterogeneous system, so that communication message interaction between the first heterogeneous system and the second heterogeneous system is realized.

In summary, the method for information interaction between heterogeneous systems of the present invention obtains a communication message through a first heterogeneous system, converts the format of the communication message into a predetermined unified message format, obtains a unified format communication message and sends the unified format communication message to a message queue cluster, receives the unified format communication message sent by the message queue cluster through a second heterogeneous system, and converts the format of the unified format communication message into a second heterogeneous system communication format, thereby implementing communication message interaction between the first heterogeneous system and the second heterogeneous system, effectively solving the problem of information chimney and information barrier caused by adopting different message buses and service frames between heterogeneous systems, fully considering information sharing between heterogeneous systems, only performing format conversion, sending and receiving of the communication message, without performing additional development work on the original heterogeneous systems, and the original heterogeneous systems do not need to change their own message service communication, and continuous and convenient integration of the heterogeneous system is ensured.

In a possible implementation manner, in order to implement service invocation interaction between heterogeneous systems, the information interaction method between heterogeneous systems in the above embodiment further includes the following steps: the first heterogeneous system acquires second heterogeneous system service calling information, converts the format of the second heterogeneous system service calling information into a preset uniform message format, obtains uniform format calling information and sends the uniform format calling information to the message queue cluster; the second heterogeneous system receives the uniform format calling information sent by the message queue cluster, and converts the uniform format calling information into a second heterogeneous system communication format to obtain second heterogeneous system communication format calling information; the second heterogeneous system generates a calling result according to the second heterogeneous system communication format calling information, converts the format of the calling result into a preset uniform message format, obtains the uniform format calling result and sends the uniform format calling result to the message queue cluster; and the first heterogeneous system receives the uniform format calling result sent by the message queue cluster and converts the format of the uniform format calling result into a first heterogeneous system communication format.

Specifically, for example, a power grid regulation and control center currently has two heterogeneous systems, a first heterogeneous system performs service invocation in an enterprise bus manner, a second heterogeneous system performs service invocation based on a unified platform, and the following description is given by using service invocation between the two heterogeneous systems. In the request/response mode, a caller of the service initiates a service request and obtains a service result from a producer of the service; in the subscription/publication mode, a service producer actively pushes a service result to a caller of the service, and the two modes mainly need to establish a uniform service description method and a uniform service route.

In a possible implementation manner, in order to facilitate the perception of the service of each heterogeneous system, the information interaction method between heterogeneous systems further includes the following steps: the second heterogeneous system acquires service registration information of the second heterogeneous system, converts the format of the service registration information of the second heterogeneous system into a preset uniform message format, obtains a uniform format service registration message and sends the uniform format service registration message to the message queue cluster; the message queue cluster sends a uniform format service registration message to a first heterogeneous system; the first heterogeneous system converts the format of the uniform format service registration message into a first heterogeneous system communication format, and the perception of the second heterogeneous system service registration message in the first heterogeneous system is realized.

Specifically, the service registration information is collected from the local queue cluster of the second heterogeneous system in a push-pull combination mode through collecting the service registration information, and the service registration information is input to the message queue cluster to be sent in an analysis stage, so that the service of the second heterogeneous system is perceived, and finally, global service registration and distribution, service state information perception and service sharing and positioning are achieved through a gateway.

In one possible implementation, the specific process of the request/response mode is as follows:

1. and synchronizing the service in the second heterogeneous system to the service center of the message queue cluster, namely sending the service registration information of the second heterogeneous system to the service center of the message queue cluster.

2. And the service center of the message queue cluster informs the protocol adapter of the gateway of the first heterogeneous system of the service registration information of the second heterogeneous system, and completes registration in the local queue cluster of the first heterogeneous system.

3. When a consumer in the first heterogeneous system calls a service registered in a second heterogeneous system of the local queue cluster, the local protocol adapter completes protocol conversion, and routes the service calling information of the second heterogeneous system to a service center of the message queue cluster through the gateway.

4. And the service center of the message queue cluster forwards the service to the gateway of the second heterogeneous system according to the actual address of the service corresponding to the service calling information of the second heterogeneous system, and completes calling of the local service through the protocol adapter of the second heterogeneous system to obtain a calling result.

5. And the second heterogeneous system converts the calling result through a local protocol adapter and returns the calling result to the consumer of the first heterogeneous system through a local gateway and a message queue cluster route.

The specific process of the subscription/publication mode is as follows:

1. a consumer of the first heterogeneous system subscribes to one service of the second heterogeneous system, and the service calling subscription information of the second heterogeneous system is synchronized to a service center of the message queue cluster through the protocol adapter and the gateway.

2. And the service center of the message queue cluster distributes the service calling subscription information of the second heterogeneous system to a gateway and a protocol adapter of the second heterogeneous system, and registers the service calling subscription information to the local cluster queue.

3. And the service of the second heterogeneous system sends the service result to the local cluster queue, and the service result is sent to the service center of the message queue cluster through the gateway after being forwarded to the protocol adapter for conversion.

4. And the service center of the message queue cluster sends the service result to the first heterogeneous system.

5. The first heterogeneous system routes the service result to the subscriber address of the first heterogeneous system through the gateway and the protocol adapter, and the service result sending is completed.

Through the mode, on the premise that the existing heterogeneous system is not additionally developed, service interaction between heterogeneous systems, namely service calling between the heterogeneous systems is achieved, the synergistic effect between the heterogeneous systems is greatly improved, and the transverse interaction capacity of each heterogeneous system inside and outside the power grid dispatching control system can be improved.

In another embodiment of the present invention, an information interaction method between heterogeneous systems is provided, where the information interaction method is applied to a first heterogeneous system of an information interaction system between heterogeneous systems, and the information interaction method between heterogeneous systems includes: acquiring a communication message, converting the format of the communication message into a preset uniform message format, obtaining a uniform format communication message and sending the uniform format communication message to a message queue cluster; the unified format communication message is used for triggering the message queue cluster to send the unified format communication message to the second heterogeneous system, and the second heterogeneous system is triggered to convert the format of the unified format communication message into the communication format of the second heterogeneous system.
