Description
Technical Field
The invention belongs to the technical field of communication, and relates to a method for carrying out multi-protocol adaptation on a charging device and the charging device.
Background
At present, a communication protocol between a charging pile and a main station (a remote service end system supporting the charging pile service, which is called the main station for short) does not have a unified national standard, so that the contents of the communication protocol are different, and most manufacturers make the communication protocol between the main station and the charging pile according to the business needs of the manufacturers.
Tcp (transport Control protocol) communication technology is a connection-oriented, reliable transport layer protocol. Connection-oriented means that a normal TCP transmission needs to be completed by establishing a specific virtual circuit connection between the TCP client and the TCP server, and this process is usually called "three-way handshake". TCP guarantees that all transmitted data can be reassembled in the normal order at the remote end by sequence numbers in data segments (segments) and guarantees the integrity of the data transmission by acknowledgements. To transmit data over TCP, a connection must be established between the hosts at both ends.
In the existing communication mode of the charging pile and the master station, a TCP communication mode of a single-port wireless network is mostly selected, and all manufacturers of communication protocols between the charging pile and the master station generally have self-defined communication protocols according to the business requirements, so that the charging piles produced by different manufacturers are difficult to be compatible with different master station servers, and the systems of the master station server master station are often required to be developed again so as to be compatible with the charging piles of different communication protocols. Moreover, due to the numerous communication protocols between the master station and the charging pile, when a master station system supporting a certain protocol is developed, if a charging pile according to a new protocol needs to be connected, the system is difficult to operate abnormally, and the system can be completed by corresponding the platform to the platform. Therefore, the resource is wasted, and the resource utilization rate and the timeliness are greatly reduced. Therefore, a multi-protocol adaptation mode capable of adopting multiple ports is needed, and perfect docking can be realized in the master station of the new system only by packing the analysis part of the master station server of the new protocol into the new system.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
The radio access techniques described herein may be used in a variety of communication systems. Examples of such communication systems include Spatial Division Multiple Access (SDMA), Time Division Multiple Access (TDMA), Orthogonal Frequency Division Multiple Access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, and the like. An SDMA system may utilize sufficiently different directions to transmit data belonging to multiple stations simultaneously. A TDMA system may allow multiple stations to share the same frequency channel by dividing the transmission signal into different time slots and allocating each time slot to a different station. A TDMA system may implement GSM or some other standard known in the art. OFDMA systems utilize Orthogonal Frequency Division Multiplexing (OFDM), which is a modulation technique that divides the overall system bandwidth into multiple orthogonal subcarriers. These subcarriers may also be referred to as tones, bins, etc. With OFDM, each subcarrier can be independently modulated with data. The OFDM system may implement IEEE802.11 or some other standard known in the art. SC-FDMA systems may utilize interleaved FDMA (ifdma) to transmit on subcarriers distributed across the system bandwidth, localized FDMA (lfdma) to transmit on blocks of adjacent subcarriers, or enhanced FDMA (efdma) to transmit on multiple blocks of adjacent subcarriers. In general, modulation symbols are transmitted in the frequency domain using OFDM and in the time domain using SC-FDMA. The SC-FDMA system may implement 3GPP-LTE (third Generation partnership project Long term evolution) or other standards. The radio access technology used by the present invention can be, for example and without limitation, based on second generation, third generation, fourth generation, and fifth generation wireless communication technologies (or referred to as 2G, 3G, 4G, and 5G technologies), and can be any non-common standard designed for physical layer and data link layer, such as communication standard that is followed inside an enterprise.
Various operations of the methods of the present invention may be performed by any suitable means capable of performing the operations, such as various hardware and/or software components (or multiple hardware and/or software components), circuitry, and/or one or more modules. In general, any of the operations shown in the figures may be performed by corresponding functional units capable of performing the operations.
The functions described herein may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the functions may be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Computer-readable media includes both computer storage media and communication media including any medium that facilitates transfer of a computer program from one place to another. A storage media may be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can comprise RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer. Also, any connection may be termed a computer-readable medium. Components of a processing system may be implemented using one or more processors. The one or more processors may be implemented with any combination of the following: general purpose microprocessors, microcontrollers, Digital Signal Processors (DSPs), Field Programmable Gate Arrays (FPGAs), Programmable Logic Devices (PLDs), controllers, state machines, gated logic circuits, discrete hardware components, dedicated hardware finite state machines, or any other suitable entity capable of executing calculations or other operations on information.
The processing system may also include a machine-readable medium for storing software. Software should be construed broadly to mean any type of instructions, whether referred to as software, firmware, middleware, microcode, hardware description language, or other terminology. The instructions may include code (e.g., in source code format, binary code format, executable code format, or any other suitable code format). The instructions, when executed by the one or more processors, cause the processing system to perform the various functions described herein.
The method of the present invention is described below with reference to the accompanying drawings. The method of the invention comprises the following steps: step 101, configuring a charging pile master station so that the charging pile master station comprises two or more ports, generally speaking, the master station should have as many ports as possible so as to connect more charging piles; step 102, two or more charging piles are set, and two or more charging piles are configured, so that each charging pile in the two or more charging piles is in communication connection with each port in the two or more ports, wherein the communication connection refers to such a connection: the two parties connected together can exchange information based on any suitable communication protocol; in the method of the invention, the two or more ports are based on at least two different radio access technologies, e.g. in the most complex case each port may communicate based on a different radio access technology. A first charging pile of the two or more charging piles sends a first message to the charging pile master station, where the first message includes a first radio access technology followed by the first charging pile, and of course, the first charging pile may also send further messages to the charging pile master station, where any of the further messages may include any information known in the charging field, such as billing information, user identity, authentication information, and the like. The charging pile master station receives the first message and configures the charging pile master station based on the first message. Configuring a charging pile master station comprises the steps that an adaptive management plug-in receives a first message; the adaptation management plug-in allocates the port adaptation plug-in based on the first message and sends a notification message to the allocated port adaptation plug-in; the port adaptation plug-in receives the notification message, and then starts adaptation processing on the port to obtain an adaptation processing result; the port adaptation plug-in sends the result of the adaptation processing to the load balancing plug-in, and the load balancing plug-in processes the result to obtain a processing result of load balancing and sends the processing result of load balancing to the port adaptation plug-in; and controlling the port to provide services for the two or more charging piles by the port adapter plug-in unit based on the processing result of the load balancing. The process may be implemented by software or hardware, for example, but not limited to, the configuration process may be implemented as follows: there are a variety of port adapter plug-ins in the primary station that can be adapted to conform to various communication protocols, such as those of WiFi, WiMax, bluetooth, ZigBee, LTE-a, etc., with the communication hardware being controlled by the adapter management plug-in. If the first radio access technology followed by the first charging pile is WiFi technology, the first charging pile may send a first message to the master station via a port (for example, referred to as a first port) connected to the first charging pile, the master station may decode the message using various protocols until the message is successfully decoded after receiving the first message based on an exhaustive method, and send the processed message to the adaptation management plug-in, based on the processed message, the adaptation management plug-in may select a corresponding port adaptation plug-in (in this embodiment, WiFi technology), and send a notification message to the segment of port adaptation plug-in, and then, after receiving the notification message, the port adaptation plug-in may start adaptation processing, for example, may download related software from a local server, or call a corresponding physical resource, to obtain a result of the adaptation processing. And then, the port adaptation plug-in sends the adaptation processing result to the load balancing plug-in, and the load balancing plug-in is responsible for generally controlling the traffic of each port, so that the problem that the user experience is influenced by too much delay caused by data congestion due to too much traffic of some ports is prevented. The load balancing plug-in processes the result transmitted by the port, judges whether the delay characteristic of the port is lower than a threshold or not, obtains a processing result of load balancing based on the judgment result, and then sends the processing result of load balancing to the port adaptation plug-in. And if the processing result of the load balancing obtained by the port adaptation plug-in is positive, controlling the corresponding port to serve the charging pile.
The port adaptation process may specifically be: the multi-protocol multi-port adaptation features are as follows: after receiving the service request of the client, the adaptation management plug-in distributes the request to the adaptation plug-in of the corresponding port by the adaptation management plug-in according to different port requests. Each adapter plug-in has a corresponding receiver, the receiver generates a corresponding processor IOHandler, and the IOHandler is responsible for receiving, analyzing and combining the corresponding specific service messages and returning response messages to the server. And distributing the generated IOHanldler analysis result to a message manager RabbitMQ message queue, combining messages needing to be returned to the client under the necessary condition according to the processing result after the RabbitMQ consumption monitoring terminal finishes responding to the service operation, and placing the messages into the message manager RabbitMQ message queue. The IOHandler monitors the message queue channel and sends the message to the server after receiving the message.
The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications as are suited to the particular use contemplated.
