Description

Technical Field

[0001] This invention belongs to the field of charging piles and relates to communication technology, specifically a distributed charging pile real-time communication system. Background Technology

[0002] Typically, multiple charging pile devices communicate with a single cloud platform service via TCP, sending data and receiving commands. However, as the number of charging piles increases, the amount of data received by the cloud platform service also increases. Without adding more cloud platform services, data processing becomes overwhelming, services cannot function properly, and in severe cases, the service may crash, leaving all charging piles offline. Adding a separate cloud platform service requires publishing a new charging pile application, pointing the application's internal cloud platform address to the new address. This leads to inconsistencies in the charging pile application version, posing certain risks, and the need to publish the application every time a new cloud platform service is added is cumbersome.

[0003] To address this, a distributed charging pile real-time communication system is proposed. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art; to this end, this invention proposes a distributed charging pile real-time communication system to solve the technical problem of insufficient data processing capacity of cloud platform services due to the increase in the number of charging piles. This invention solves the above problem by adding a gateway service.

[0005] To achieve the above objectives, a first aspect of the present invention provides a distributed charging pile real-time communication system, including a charging pile monitoring module, a gateway service module, and a communication module;

[0006] The charging pile monitoring module is used to monitor the operating status of the charging pile; wherein, the operating status includes online, offline and fault status;

[0007] When a charging pile is put into service, the charging pile monitoring module sends a gateway service request to the gateway service module.

[0008] The gateway service module is used to obtain all currently operating cloud platform services and generate a cloud platform service list after receiving the gateway service request.

[0009] Return the address information of one of the cloud platform services in the cloud platform service list to the charging pile;

[0010] The communication module is used to establish communication between the charging pile and the cloud platform service.

[0011] Preferably, generating a cloud platform service list includes the following steps:

[0012] The gateway service module obtains the technical specifications information of the charging pile; wherein, the technical specifications information includes the communication protocol, interface standard and data format used by the charging pile;

[0013] Based on the technical specifications, the cloud platform service library is filtered to obtain cloud platform services with the same technical specifications, and a cloud platform service list is generated.

[0014] Establishing communication between charging piles and cloud platform services requires compatibility, necessitating the use of the same communication protocols, data formats, and interface standards by both parties. Therefore, it is necessary to select cloud platform services that can establish communication with charging piles from among all available cloud platform services to facilitate the subsequent selection of suitable cloud platform services.

[0015] Preferably, the cloud platform service library is used to store the technical specifications of various cloud platform services;

[0016] The cloud platform service library can manage and update the stored technical specifications information, ensuring the accuracy and timeliness of the information; this can provide users with more reliable and practical filtering and comparison services.

[0017] Preferably, returning the address information of one of the cloud platform services in the cloud platform service list to the charging pile includes the following steps:

[0018] The gateway service module obtains the number of charging piles connected to each cloud platform service in the cloud platform service list; and marks the number of charging piles as Sn; the fewer the number of charging piles connected to a cloud platform service, the higher the stability of the cloud platform service, so the number of charging piles can be used as an influencing parameter of the cloud platform service index.

[0019] The gateway service module obtains the configuration information of each cloud platform service in the cloud platform service list, and assigns values ​​to the configuration parameters of the cloud platform services according to the configuration information; the configuration parameters are marked as Pn; the higher the configuration of the cloud platform service, the faster the processing speed of the cloud platform service; therefore, the configuration parameters can be used as the influencing parameters of the cloud platform service index.

[0020] Among them, the higher the configuration of the cloud platform service, the larger the corresponding configuration parameters;

[0021] Based on the number of charging piles and the configuration parameters, the cloud platform service index is calculated and obtained, and the cloud platform service index is marked as ZSn;

[0022] The formula for calculating the cloud platform service index is as follows:

[0023]

[0024] Arrange the cloud platform service indices in ascending order to obtain the cloud platform service index sequence;

[0025] Obtain the first cloud platform service in the cloud platform service index sequence and mark it as the target cloud platform service;

[0026] Where n is the number of the cloud platform service, and the value of n is 1, 2, 3...N, N is the total number of cloud platform services in the cloud platform service list; N is an integer greater than 0;

[0027] The gateway service module sends the address information of the target cloud platform service to the charging pile.

[0028] Preferably, when the minimum cloud platform service index exceeds one, the cloud platform service with the highest configuration parameters is selected as the target cloud platform service; this application prioritizes allocating a server with a higher configuration cloud platform service.

[0029] Preferably, the gateway service module is further configured to monitor the operating status and load of the cloud platform service after the address information is sent.

[0030] When the cloud platform service encounters an abnormal situation, the gateway service obtains new address information and sends it to the charging pile.

[0031] Preferably, the communication module establishes communication between the charging pile and the cloud platform service, including the following steps:

[0032] The charging pile receives the address information and establishes communication with the cloud platform service based on the address information.

[0033] After the communication connection is established, the charging pile sends request data to the target cloud platform service and receives response data from the cloud platform service.

[0034] The requested data includes charging pile status, charging request, payment information, and other information.

[0035] The response data includes charging status information, payment results, error messages or prompts, and other relevant information.

[0036] Preferably, it also includes a monitoring module;

[0037] The monitoring module performs heartbeat detection on the charging pile and cloud platform services;

[0038] If the connection is interrupted, re-establish the connection;

[0039] To maintain communication stability, charging stations and cloud platform services typically perform heartbeat checks periodically to confirm that the connection is still valid.

[0040] Compared with the prior art, the beneficial effects of the present invention are:

[0041] This invention obtains the technical specifications of charging piles through a gateway service module; filters the cloud platform service library based on the technical specifications to obtain cloud platform services with the same technical specifications, and generates a cloud platform service list; generates a cloud platform service list by generating the obtained cloud platform services; quickly and accurately finds cloud platform services that match the charging piles, reducing the possibility of manual intervention and incorrect matching; ensures that the selected cloud platform services match the technical requirements of the charging piles, and reduces safety risks caused by incompatibility or technical defects;

[0042] The gateway service module obtains distance data between the charging pile and cloud platform services in the cloud platform service list. Based on the log files of the cloud platform services in the list, the gateway service module calculates the cloud platform service index according to the distance data, stability data, and rate data. The cloud platform service indices are sorted in ascending order to obtain a cloud platform service index sequence. The first cloud platform service in the cloud platform service index sequence is selected and marked as the target cloud platform service. The gateway service module sends the address information of the target cloud platform service to the charging pile. Evaluating and selecting the best cloud platform service based on multiple factors helps ensure that the charging pile can connect to the best-performing and most reliable cloud platform service, improving service availability and response speed.

[0048] Please see Figures 1-3 The first aspect of the present invention provides a distributed charging pile real-time communication system, including: a charging pile monitoring module, a gateway service module and a communication module;

[0049] The charging pile monitoring module is used to monitor the operating status of the charging pile;

[0050] Specifically, the operating status includes online, offline, and fault states;

[0051] When a charging pile is put into service, the charging pile monitoring module sends a gateway service request to the gateway service module.

[0052] In one specific embodiment, a user activates charging station A.

[0053] The charging pile monitoring module detects that charging pile A is online and sends a gateway service request to the gateway service module.

[0054] The gateway service module is used to obtain all currently operating cloud platform services and generate a cloud platform service list after receiving the gateway service request.

[0055] Return the address information of one of the cloud platform services in the cloud platform service list to the charging pile;

[0056] In this embodiment, generating the cloud platform service list includes the following steps:

[0057] The gateway service module obtains the technical specifications information of the charging pile;

[0058] Specifically, the technical specifications include the communication protocols, interface standards, and data formats used by the charging piles. It should be noted that the technical specifications can be obtained by reading the technical documents of the charging piles, communicating with suppliers or manufacturers, etc.

[0059] It should be further explained that the communication protocols used by charging piles include TCP / IP, UDP, HTTP, etc.; different communication protocols have different data transmission methods and communication mechanisms, so it is necessary to determine the communication protocol used by the charging pile first.

[0060] The interface standards used by charging piles include RESTful API, SOAP, etc.; the interface standard determines the data exchange method and format, so it is necessary to clarify the interface standard used by the charging pile.

[0061] The data formats sent and received by charging piles include JSON, XML, etc.; different data formats have different encoding and decoding methods, so it is necessary to specify the data format used by the charging pile.

[0062] Based on the aforementioned technical specifications, the cloud platform service library is filtered to obtain cloud platform services with the same technical specifications, and a list of cloud platform services is generated. It should be further noted that the technical specifications of relevant cloud platform services can be queried through search engines, industry news websites, technical forums, and other means.

[0063] In one specific embodiment, after receiving a gateway service request, the gateway service module obtains the technical specifications information of charging pile A.

[0064] Charging pile A uses HTTP as the communication protocol; SOAP as the interface standard; and JSON as the data format.

[0065] Filter cloud platform services within the cloud platform service library that use HTTP as the communication protocol, SOAP as the interface standard, and JSON as the data format.

[0066] Generate a list of cloud platform services from the acquired cloud platform services;

[0067] All cloud platform services listed in the cloud platform service list use HTTP as the communication protocol, SOAP as the interface standard, and JSON as the data format.

[0068] In this embodiment, the cloud platform service library is used to store the technical specifications of various cloud platform services;

[0069] In this embodiment, returning the address information of one of the cloud platform services in the cloud platform service list to the charging pile includes the following steps:

[0070] The gateway service module obtains the number of charging piles connected to each cloud platform service in the cloud platform service list; and marks the number of charging piles as Sn.

[0071] The gateway service module obtains the configuration information of each cloud platform service in the cloud platform service list, and assigns values ​​to the configuration parameters of the cloud platform services according to the configuration information; the configuration parameters are marked as Pn;

[0072] Specifically, the higher the configuration of the cloud platform service, the larger the corresponding configuration parameters;

[0073] Based on the number of charging piles and the configuration parameters, the cloud platform service index is calculated and obtained, and the cloud platform service index is marked as ZSn;

[0074] The formula for calculating the cloud platform service index is as follows:

[0075]

[0076] It should be noted that when there is more than one minimum cloud platform service index, the cloud platform service with the highest configuration parameters will be selected as the target cloud platform service.

[0077] Arrange the cloud platform service indices in ascending order to obtain the cloud platform service index sequence;

[0078] Obtain the first cloud platform service in the cloud platform service index sequence and mark it as the target cloud platform service;

[0088] The cloud platform service index for Cloud Platform No. 4 is 1.

[0089] The cloud platform service index of Cloud Platform No. 1 is the lowest, so Cloud Platform No. 1 is set as the target cloud platform service.

[0090] It should be further explained that n is the number of the cloud platform service, and the value of n is 1, 2, 3...N, where N is the total number of cloud platform services in the cloud platform service list; N is an integer greater than 0.

[0091] The gateway service module sends the address information of the target cloud platform service to the charging pile;

[0092] In this embodiment, the gateway service module is also used to monitor the running status and load of the cloud platform service after the address information is sent.

[0093] If a cloud platform service is found to be malfunctioning or overloaded, the gateway service needs to adjust the load balancing strategy in a timely manner, obtain new address information, and send it to the charging pile.

[0094] The communication module is used to establish communication between the charging pile and the cloud platform service.

[0095] The communication module establishes communication between the charging pile and the cloud platform service, including the following steps:

[0096] The charging pile receives the address information and establishes communication with the target cloud platform service based on the address information.

[0097] Specifically, the communication methods between charging piles and cloud platform services include protocols such as HTTP and WebSocket, which need to be determined based on actual needs and network environment.

[0098] In one specific embodiment, the charging pile obtains the address information of the target cloud platform service and establishes a communication connection with the target cloud platform service through the TCP protocol based on the address information of the target cloud platform service;
