The release environment was used to Centos7, JDK1.8. The internet of vehicles terminal access system of this embodiment includes a terminal layer, a service support layer, and an infrastructure layer, and is described in terms of functional characteristics in three dimensions of a terminal, a service, and an infrastructure:
the terminal layer adopts different security checks mainly aiming at different terminal types and different protocol types
The method comprises the steps of determining the terminal type of an access terminal and the corresponding network protocol type, and determining the corresponding security verification mode based on the terminal type and the network protocol type 0; wherein, in determining the net
When the network protocol type is tcp, load balancing is carried out by using a haproxy; when the network protocol type is determined to be mqtt, the network protocol type is bridged by an emqx server, and when the network protocol type is determined to be http, the Nginx and the gateway forward. The access terminal comprises a vehicle terminal, a host system, a vehicle owner APP and a supervision platform.
The service support layer is used for managing the state of the access terminal 5 and carrying out data receiving and transmitting, protocol analysis and message processing based on a plurality of micro-service modules developed by the spring boot; the micro service modules are taken as the components through kafka
The message middleware performs peak clipping decoupling on the data; the service boundaries of each service module are clear, distributed deployment can be performed, dynamic capacity expansion is performed, and k8s is all incorporated for management.
As shown in fig. 1 and 2, the service support layer includes a terminal access module (access), an mqtt access module (mqtt client), a protocol analysis module (analysis), a message processing module (dataCenter), an interface service module, an alarm module (alarm), a message forwarding module (dataForward), and an interface module (webService); and each module uses kafka as message middleware to carry out peak clipping decoupling of data, and all the modules are stateless service and can dynamically expand capacity according to the flow of the request data at any time.
The terminal access module takes the netty framework as a core, manages all tcp connections, manages the state of the access terminal, transmits and receives data, processes tcp messages, intercepts, decrypts and restores the tcp messages according to a protocol, and transmits the tcp messages to the protocol analysis module for further processing. As shown in fig. 3, after the third party platform logs in, the vehicle data is uploaded to a terminal access module (terminal access) which uploads the vehicle data to a message forwarding module (dataForward).
The mqtt access module takes the mqtt communication framework as a core, subscribes to the mqtt theme message and receives and transmits the mqtt message.
The protocol analysis module is used for encoding and decoding the tcp message, converting the binary message into a protocol object or converting the protocol object into the binary message; the cglib framework can be used for dynamically loading jar packets, namely, the protocol can be subjected to hot loading, and a new protocol is seamlessly connected.
And the message processing module is used for carrying out service processing on all data and classifying and storing service objects. The method comprises the steps of performing service processing on all data received by a terminal access module, an mqtt access module and an interface service module, classifying and storing service objects, and generating corresponding vehicle warning and early warning messages; and processing the vehicle instruction and monitoring the vehicle state in real time. And transmitting part of vehicle data (vehicle alarm, early warning message and vehicle state) to a message forwarding module for subsequent processing.
The alarm service module is used for processing the vehicle alarm and early warning information and pushing the vehicle alarm and early warning information to corresponding people or vehicles. The supervision platform warning and early warning message can be pushed to the corresponding person or vehicle.
And the message forwarding module is used for connecting a supervision platform in a country or a place, and uploading the vehicle state, the vehicle alarm and early warning message to the corresponding supervision platform according to the country and the landmark to which the vehicle belongs. As shown in fig. 3, the message forwarding module dataForward logs in the supervision platform (national platform), after receiving a login success response of the supervision platform, sends a heartbeat link to the supervision platform, uploads data, and if the link is judged to be disconnected, logs in again, and after receiving a login success response of the supervision platform, carries out data retransmission.
The interface service module is used for managing the external http interface and processing the man-vehicle interaction service.
And the infrastructure layer is used for deploying a message middleware cluster, and the middleware cluster is used for classifying and storing data of different service types. The infrastructure layer includes a kafka cluster and databases including a Redis database, a mysql database, and a MongoDB database.
As shown in fig. 4, after the connection is established, the vehicle terminal uploads data through the terminal access module, the terminal access module sends the original data to the protocol analysis module for analysis, and the analysis sends the original data to the message processing module dataCenter based on the protocol object for processing the service, classifies and stores the service object, and generates corresponding vehicle warning and early warning messages; if the alarm information exists, the alarm information is sent to an alarm module (alarm), the alarm module (alarm) stores the alarm data into a database, a message processing module dataCenter stores the vehicle data into the database, meanwhile, the message processing module sends the alarm data to a message forwarding module (dataForward), a terminal access module (access) sends the original data to the message forwarding module (dataForward), and the message forwarding module (dataForward) sends the original data and the alarm information to a supervision platform.
Compared with the single service scheme in the prior art, in the embodiment, the message access, the message encoding and decoding, the message processing and the message forwarding are all in one service, and a complete set of service needs to be redeveloped by adding one terminal or protocol, so that the service performance is poor, the service is bloated, and the expandability is poor.
The multi-protocol fusion terminal access system in the embodiment has clear service boundary, high performance, and high expandability, and can complete access by only carrying out small modification on corresponding access service or protocol analysis service no matter what type of protocol is added or the terminal, wherein the kakfa is used as a middleware message to be processed in parallel to more than one million levels. After the function modularization, the method can perform targeted optimization and capacity expansion, and is quite convenient for checking problems.
