Description
Technical Field
The invention relates to the technical field of charging service program thermal upgrading, in particular to a pile service program thermal upgrading system and method of an electric vehicle charging service platform.
Background
With the fact that new energy vehicles have higher and higher occupation ratios, as a part of new capital construction, more and more merchants participate in design, manufacture and operation of electric vehicle charging piles.
According to the standard of the middle-power-grid connection T/CEC 102, charging pile manufacturers develop own communication protocols of the charging piles and the charging platform in a customized mode, different manufacturers have different protocols, and the communication protocols of the charging piles of the same manufacturer in different ages are different.
The same charging platform service needs to be accessed to thousands of charging piles, in order to access to the charging piles of different manufacturers, the charging platform needs to analyze various different communication protocols, and when one communication protocol is upgraded, the charging platform service is often required to be upgraded.
Currently, a charging pile program is connected with a back-end pile service program developed by each platform by establishing a TCP direct connection mode or an MQTT protocol. The upgrade and restart of the back-end service will cause the connection between the stub and the service to be disconnected, and the charging service will be interrupted briefly.
Charging platform operators often choose to upgrade in the morning and inform customers and corporate management layers in advance. But the electricity price is relatively cheap in the morning, and many buses and operating vehicles still charge in the morning, and the sudden restart of the service can influence the charging of the buses and the operating vehicles. And the availability requirement of the operating vehicle on the charging service platform is very high, and once the charging service platform is not charged, the normal development of company operating business is influenced.
The more charging pile communication protocols the charging platform needs to support, the more times the platform service needs to be upgraded and restarted, and the more times the restarting causes charging service flash.
In order to improve the platform service availability, service interruption caused by platform service restart needs to be avoided as much as possible.

A universal calling interface is designed between adjacent layers, different layers have different implementations based on interface programming, and cross-layer calling is not allowed. After the charging service is started, the background task periodically scans the specified directory, tries to load the dynamic library of the resolver which realizes the corresponding level calling interface, and only stores the latest version of each communication protocol resolver.

The embodiment further provides a pile service program thermal upgrading method for an electric vehicle charging service platform, and the pile service program thermal upgrading system adopting the electric vehicle charging service platform comprises the following steps: s1, after receiving the opposite end data flow, the session layer judges whether the opposite end communication protocol information is stored, if yes, the protocol resolver example is obtained from the resolver manager according to the protocol name, and then the step S3 is carried out, and if not, the step S2 is carried out; s2, searching a corresponding protocol analyzer from the protocol analyzer list by adopting a polling method, judging whether the protocol analyzer is successfully matched, if so, entering S3, and if not, feeding back that the matching is failed; and S3, replacing the resolver manager member variable as a new protocol resolver object instance during upgrading without informing a session layer and an application layer.
Referring to fig. 1 and 2, the electric pile access service of the platform is divided into two parts:
1) the Internet of things part is directly connected with the charging piles TCP through a Netty network framework, and at most 2 ten thousand charging piles can be connected into the same service program.
2) The internet part receives various requests of starting and stopping charging, inquiring charging progress and the like through a Java Spring framework; meanwhile, messages such as telegraph asynchronous response, charging real-time data report and the like are sent to other micro services through message queue middleware such as a RabbitMQ.
The Netty channels encapsulate a network layer, each charging pile is connected with one charging pile in a long way, corresponds to one Channel instance, and sends and receives messages through the Channel instance to communicate with the charging piles through a network.
Referring to fig. 2, right-most:
EpNettySession, PresentationProxy, AppUpdateHandlerImpl correspond to the session layer, presentation layer, application layer respectively, and are held to facilitate cross-layer calling.
And respectively creating a Channel object, an EpnetySession object, a PresentationProxy object and an AppUpdateHandlerImpl object for each charging pile. For hot upgrade convenience, the presentation layer applies the proxy mode, designing the PresentationProxy as the requesting proxy, and does not hold the protocol parser EpPresentation object. The PresentationProxy also implements the interface of the presentation layer as a proxy, but it is only responsible for acquiring a corresponding protocol parser and forwarding a request, and does not actually implement the service logic related to the presentation layer.
The same electric pile protocol has a plurality of charging piles, and different context objects need to be quoted for different piles in the same EpPresention instance, so that the presentationContext is designed to package the electric pile request context.
When the EpPresence is to send a message to a specified stub, the request context such as the session layer, application layer object or stub number related to the stub is obtained through the PresentionContext. The introduction of PresentationContext makes it possible for multiple charging piles to dynamically depend on, rather than hold, a protocol parser.
The connection is intermittent, the Channel corresponding to the connection is dynamic and evanescent, but the session layer is stable, and the session is released only when the stub is continuously disconnected. Therefore, the life cycle of the Channel instance is inconsistent with the EpnetySession, and the Channel instance is not designed to have a strong dependence relationship with each other. And recording the stub ID by the Channel and the session layer, establishing dynamic dependence by means of EpSessionadmin, and searching the corresponding object instance through the stub ID when the opposite side needs to be called.
EpSessionadmin is used as a container of the Channel and the Session, and the Channel and the Session objects are stored in a key-value pair mode by taking the stake ID as a key. And when the connection is connected and the opposite end pile ID is analyzed according to the protocol, saving the corresponding Channel and the Session. And removing the Channel when the connection is disconnected, and removing the Session corresponding to the stub when the Session is overtime after the connection is disconnected for a period of time.
In order to realize hot upgrade, the protocol analysis part which is easy to change is encapsulated in the subclass, and the subclass realizes the protocol Impl abstract class. The PresentationLoader periodically scans and appoints a Jar packet directory, loads various implementation classes of the protocol Impl, and subclasses of the presentation loader inherit to the protocol Impl, thereby realizing a query interface of protocol names and versions, realizing a protocol matching check interface and the like, and only retaining the analyzers of the latest version of each protocol.
In each Channel, the protocol name and the opposite end stub ID are stored. For the newly-built Channel, there is no protocol and pile ID information, at this time, it is necessary to wait for the protocol frame sent by the opposite end to arrive, and then after the Channel receives the network flow data, poll each protocol impl instance in the PresentationLoader, and the protocol impl instances try to determine whether the protocol identifiers are consistent according to their respective protocol definitions, and then cut out the whole protocol frame according to the length field. If the frame has CRC check, whether the frame data is correct is calculated according to the CRC. If no check information exists, the protocol identification is compared again after the arrival of the subsequent frame data.
When the Jar package with the same protocol is upgraded in a hot mode, the class searched by polling is required to replace the class with the same name loaded in the memory before. Java defaults to loading classes from a parent ClassLoader, so when a jar package is upgraded, the classes with the same package name and class name are loaded into a memory, and the class cannot be replaced by new classes by default. Therefore, in the implementation, the loadClass method of the URLClasLoader needs to be customized, and the class in the newly upgraded jar package is not loaded from the parent loader, but the Java class is loaded from the jar after the upgrade.
And after constructing the network layer, the session layer and the presentation layer instance corresponding to the stub in the hierarchical model, binding the application layer instance. The application layer instance is created and initialized by an upper layer, the presentationLoader provides a registration method for registering a callback function by the application layer, and after the protocol parser is loaded successfully and parses out the stub ID, the presentation layer obtains the application layer instance through the callback and holds the other side.
As can be seen from fig. 2, the life cycle of the protocol resolver is managed by a globally unique management class instance PresentationLoader, and other classes are dynamically dependent and find the protocol resolver according to the protocol name if necessary. When the protocol parser is loaded into a new version protocol parser, the presentationLoader can finish upgrading without notifying other layer instances after replacing the protocol parser.
When the messages are transmitted layer by layer from bottom to top, each Channel object of the network layer stores the stub ID analyzed according to the protocol frame, and after the messages are received, the corresponding session layer object can be obtained by accessing the EpSessionadmin through the stub ID. Since EPNettySession and PresentationProxy hold each other, PresentationProxy and appupdatehandlerifl hold each other. The network layer calls the session layer, the presentation layer is called after the session layer is processed, and the application layer is called after the presentation layer is processed.
And the application layer saves the application layer instance corresponding to each pile by taking the charging pile ID as a main key. When the pile needs to be informed to start or stop charging and inquire the real-time charging state of the pile, an ApUpdateHandlerImpl instance is obtained from EpComComClientService according to the pile ID, and the request sequentially passes through layers from top to bottom and then reaches the charging pile.
