It should be noted that the execution main body in the embodiment of the present invention is an agent module providing a unified access function, and the agent module may be installed in the charging operation platform, or may operate independently as a device. It can be understood that charging piles produced by different manufacturers generally have different communication protocols, and therefore, an implementation scenario addressed by the embodiment of the present invention is a situation of how charging piles of different communication protocols are uniformly connected to the same charging operation platform for centralized management.
Specifically, in step 201, before the charging pile is managed, the charging pile needs to be connected to the charging operation platform, and the number and the type of the charging pile are not specifically limited in the embodiment of the present invention. For each charging pile, if the charging pile is successfully accessed into the charging operation platform, the connection relationship between the charging operation platform and the charging pile is considered to be established.

It should be noted that, in the process of establishing a connection and the process of managing charging between step 201 and step 202, the charging pile and the charging operation platform need to perform information interaction, and the interaction process is transmitted in the form of a message, so as to unify the processes, fig. 3 is a schematic diagram illustrating a correspondence relationship between the charging pile operation management platform, the charging pile and a communication protocol provided in the embodiment of the present invention, as shown in fig. 3, in advance, according to a protocol of each manufacturer, each charging pile performs message configuration according to a preset message type, and the following contents are generally configured according to needs: the method includes configuring a sign-in message (BootNotification), configuring a Heartbeat message (Heartbeat), configuring an authentication message (authorization), configuring a charging start message (remotestarttransmission), configuring a charging process data message (StatusNotification), configuring a charging end message (remotesstoprelay), configuring a settlement message (stoprelay), configuring a management message and other message types, and then enabling a message engine preset in the embodiment of the invention to correspond the message types to specific message contents to form a complete message. Similarly, when a message is processed, the same message issuing and message analysis can be realized for any type of charging pile by calling the preset message engine in the embodiment of the invention, and the adaptation of different equipment to different protocols is realized.
According to the unified access management method for the multi-communication-protocol charging piles, unified message configuration and processing modes are provided for the electric vehicle charging piles of various communication protocols, so that unified management under the same platform is achieved, and the whole management process is more reasonable and efficient.

It should be noted that, in the charging process, information such as current, voltage, soc of charging can be reported to the charging operation platform by the charging pile, and the charging operation platform is used for monitoring or other graphical displays.
On the basis of the foregoing embodiment, the managing a charging process of a charging pile for which a connection relationship is established further includes:
receiving a charging ending settlement message sent by the charging pile;
and calculating the deduction fee according to the charging end settlement message.
It can be understood that charging of the charging pile is required to be charged for a user, and the charging process provided by the embodiment of the invention further includes that when charging is completed, the charging pile sends a charging completion settlement message to the charging operation platform, and the charging operation platform settles charging and deducts fees.

The message issuing function is to send a message to the charging pile, fig. 4 is a schematic diagram of signaling interaction in a message issuing process provided by the embodiment of the present invention, and as shown in fig. 4, the signaling interaction includes: the message engine executes xml by parsing the preloaded message, and starts message transmission. The process may be performed once or periodically. And then calling a pre-loaded message to process a sending process configured in the xml, then assembling the pre-loaded message to define the message configured in the xml, then sending the message to the charging pile through a communication module, wherein the communication module is responsible for a module for communicating with the charging pile, supports communication protocols such as tcp, udp or modbus and the like, and finally outputting the xml according to the pre-loaded message in the sending process to store a file or store a library to finish message sending. It should be noted that 1.1-1.4 shown in fig. 4 are only used to indicate the execution sequence of signaling.
Fig. 5 is a schematic diagram of signaling interaction in a message parsing process according to an embodiment of the present invention, as shown in fig. 5, the message parsing process is mainly used for receiving and parsing a message interacted between a charging operation platform and a charging pile in a charging process, and mainly includes: and after monitoring the message sent back by the charging pile, the communication module informs a message engine, then the message engine calls a pre-loaded receiving and processing flow according to the message code, then defines xml by the pre-loaded message to analyze the message, transfers the message to a correspondingly configured message type branch to process, and finally outputs and stores the receiving process.
