In the following description, references to the terms "first \ second \ third" are only to distinguish similar objects and do not denote a particular order, but rather the terms "first \ second \ third" are used to interchange specific orders or sequences, where appropriate, so as to enable the embodiments of the application described herein to be practiced in other than the order shown or described herein.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.
Before further detailed description of the embodiments of the present application, terms and expressions referred to in the embodiments of the present application will be described, and the terms and expressions referred to in the embodiments of the present application will be used for the following explanation.

2) Kaffa (Kafka) cluster: a cluster with a Kafka messaging system is running. The Kafka messaging system, which is a kind of publish-subscribe messaging system, is widely used due to its high message throughput efficiency, and is a distributed system that can be operated on a cluster consisting of one or more servers.
In the related technology, after the internet of things equipment uploads the message to the internet of things system, the internet of things system firstly analyzes the data to obtain the message type, then caches the data to a specific message queue middleware according to the message type, and meanwhile, the specific message consumer service carries out consumption processing. The logic has strong coupling between service and message processing, and when the message type is newly added, not only the access service needs to be adapted and adjusted, but also the consumption service needs to be adapted and adjusted. In addition, when some types of message data need to be processed by multiple consuming services, the related adjustment of the service code is usually required, which increases the service intrusiveness of the system architecture. The system needs to support horizontal expansion and access of massive internet of things devices, the message consumption processing makes it difficult to process new types of messages when the system is expanded or other internet of things devices are accessed, if the system is adapted to the new types of internet of things messages, the system needs to be upgraded and modified, the workload of upgrading and modifying the system is large, and manpower and material resources are consumed.

The message processing method of the internet of things provided by the embodiment of the present application is described below with reference to exemplary applications and implementations of the terminal provided by the embodiment of the present application. Referring to fig. 3, fig. 3 is an optional schematic flow chart of the message processing method of the internet of things provided in the embodiment of the present application, and as shown in fig. 3, the message processing method of the internet of things includes the following steps:
the message consumer service is used for consuming and processing the Internet of things messages in the associated target message queue.
It should be noted that the message of the internet of things is a message generated by the device of the internet of things. The internet of things equipment comprises one or more message producer services, and the message producer services generate corresponding types of internet of things messages. In this application embodiment, the internet of things device may be a vehicle-mounted device accessing to the internet of vehicles, and the message producer service may be, for example, a Global Positioning System (GPS) service, a speed measurement service, and the like, which is not limited in this application embodiment. In actual implementation, after the message producer service in the internet of things equipment generates the internet of things message, the internet of things message is sent to the electronic equipment. The electronic equipment receives the Internet of things message sent by the Internet of things equipment. In the embodiment of the application, an internet of things message generated by a message producer service corresponds to one message type, for example, a GPS message generated by a GPS service corresponds to one message type, and speed data obtained by speed measurement service corresponds to another message type.
In actual implementation, after receiving the message of the internet of things, the electronic device analyzes the message of the internet of things to obtain a message type of the message of the internet of things. And then, determining at least one message consumer service corresponding to the message of the Internet of things based on the message type of the message of the Internet of things and the corresponding relation between the message type and the message consumer service. The message consumer service is used for consuming and processing the messages of the Internet of things. The message consumer service may be, for example, a navigation service, an overspeed warning service, etc., which is not limited in this embodiment of the present application. The navigation service can consume and process the GPS information and utilize the GPS information to navigate. The overspeed alarm service can perform consumption processing on the speed data, namely the internet of things message, judge whether overspeed occurs or not based on the speed data, and send out an alarm when overspeed occurs.
In an embodiment of the application, one message type may correspond to one or more message consumer services. That is, there may be one or more message consumer services that perform consumption processing on the internet of things message of the same message type, for example, for the internet of things message of the message type of the GPS message, the corresponding message consumer service may be a navigation service, a ticket purchase platform service, an express delivery service, and the like.
In some embodiments, a message bus service is arranged in the electronic device, the message bus service is constructed on an access service of the internet of things device, and the electronic device implements the internet of things message processing method provided by the embodiments of the present application through the message bus service. Illustratively, referring to fig. 4, fig. 4 is an alternative schematic diagram of the message bus service provided by the present application. The message bus services include a message distribution service, a producer-proxy service (producer-proxy), a consumer-proxy service (consumer-proxy), and a Kafka cluster. In the embodiment of the application, the Kafka cluster provides a caching function and a message subscribing and publishing function for the internet of things messages, so that any service accessing the message bus can subscribe the internet of things messages of a specific message type generated by other services. The message Identifier (ID) shown in fig. 4 refers to an Identifier of the internet of things message, and the subscription ID refers to an Identifier of a message consumer service subscribing to the corresponding internet of things message. Based on the message bus service shown in fig. 4, referring to fig. 5, fig. 5 is an optional flowchart of the message processing method of the internet of things provided in the embodiment of the present application, and step 302 may also be implemented by the following method:
step 502, reading the internet of things message from the initial message queue through a message distribution service, and determining at least one message consumer service corresponding to the internet of things message based on a corresponding relationship between message types and message consumer services;
the internet of things messages in the target message queue are sent to the message consumer service through the consumer proxy service, so that the message consumer service can consume and process the received internet of things messages. In actual implementation, the internet of things equipment reports the internet of things message generated by the message producer service to the message bus service, and processes the received internet of things message through the producer agent service in the message bus service. In this embodiment of the present application, step 501 may also be implemented as follows: analyzing the message of the Internet of things through a producer agent service to obtain the message type of the message of the Internet of things; and adding the message of the Internet of things to the corresponding initial message queue through a producer agent service based on the corresponding relation between the message type and the initial message queue.
In actual implementation, the electronic device receives the internet of things message generated by the message producer service of the internet of things device through the producer agent service, analyzes the received internet of things message through the producer agent service to obtain the message type of the internet of things message, and adds the internet of things message to the corresponding initial message queue based on the corresponding relation between the message type and the initial message queue. Specifically, when the electronic device obtains a new message type through parsing, an initial message queue is created for the message type, and the created initial message queue is bound to the message type. Here, the electronic service may set a queue identifier for each initial message queue to distinguish between different initial message queues.
It should be understood that the electronic device provided in the embodiment of the present application may communicate with multiple pieces of internet of things devices, different pieces of internet of things devices may generate internet of things messages of the same message type, and may also generate internet of things messages of different message types.
It should be noted that, in the embodiment of the present application, the initial message queue is disposed in the Kafka cluster. Referring to fig. 6, fig. 6 is a schematic diagram of an alternative architecture of an internet of things message processing system provided in the embodiment of the present application. The electronic equipment adds the received Internet of things message to the corresponding initial message queue according to the message type through the producer agent service, reads the Internet of things message in the initial message queue from the Kafka cluster through the message distribution service, and performs consumption processing on the read Internet of things message. Here, the consumption processing of the message distribution service on the internet of things message specifically includes analyzing the internet of things message to obtain a message type of the internet of things message, and determining at least one message consumer service corresponding to the internet of things message based on a correspondence between the message type of the internet of things message and the message consumer service. Specifically, the corresponding relationship between the message type and the message consumer service is a subscription relationship between the message type and the message consumer service, and the message consumer service may subscribe to the internet of things message of the corresponding message type and store the subscription relationship in the Kafka cluster. Here, the subscription relationship may be a correspondence between a message type and an identification of a message consumer service.
Then, the electronic device determines, through the message distribution service, at least one message consumer service corresponding to the internet-of-things message read from the initial message queue based on a correspondence (i.e., a subscription) between the message type and the message consumer service, and then determines an associated target message queue based on the message consumer service. It should be noted that each message consumer service corresponds to a target message queue. And the electronic equipment adds the read internet of things message to each target message queue through the message distribution service.
In some embodiments, the message distribution service distributes the message in the initial message queue by means of consumption processing, and specifically, step 104 may also be implemented by: performing consumption processing on the Internet of things message to obtain a message copy of the Internet of things message; adding the message copy to each target message queue.
In actual implementation, the electronic device performs consumption processing on the read internet of things message through the message distribution service, copies the read internet of things message to obtain a corresponding message copy, and adds the message copy to each target message queue. It should be noted that the internet of things message after being consumed and processed is deleted by the electronic device.
In some embodiments, after the electronic device adds the internet of things message to the target message queue through the message distribution service, the electronic device may further continue to process the internet of things message in the target message queue. Specifically, referring to fig. 7, fig. 7 is an optional flowchart of the message processing method for the internet of things provided in the embodiment of the present application, and after step 104, the following steps may be further performed:
In actual implementation, the electronic device pushes the internet of things message in the target message queue to a corresponding message consumer service through the consumer proxy service. Specifically, the electronic device reads the internet of things message from the target message queue at a first push rate, and pushes the internet of things message queue read from the target message queue to a message consumer service associated with the corresponding target message queue. And after receiving the Internet of things message, the message consumer service carries out consumption processing on the received Internet of things message. It should be noted that different types of message consumer services perform corresponding consumption processing on the internet of things message for the service function. For example, the message consumer service, navigation service, may perform consumption processing on the received GPS message, and perform map navigation using the GPS message.
In some embodiments, the electronic device may further control a push rate of the internet of things messages in the target message queue. Specifically, referring to fig. 8, fig. 8 is an optional flowchart of the method for processing the message of the internet of things provided in the embodiment of the present application, and after step 701, the following steps may also be performed:
In practical implementation, when a bottleneck occurs in the message consumer server, which causes that the message consumption speed of the message consumer service cannot catch up with the message production speed, the message needs to be limited; when the message cannot be processed due to the abnormal consumption service, the message needs to be cached, so that the message can be continuously processed when the service of the message consumer is recovered, and the data loss is avoided. Specifically, the flow control instruction may be generated by being automatically triggered based on a certain condition, for example, when the electronic device detects that the consumption rate of the internet of things message in the target message queue is less than the generation rate of the internet of things message in the initial message queue, the push rate of the internet of things message in the target message queue needs to be limited, and then the flow control instruction for reducing the push rate is generated. The flow control instructions may also be generated upon receiving a feedback message of the message consumer service, which may be, for example, too heavily loaded by the message consumer service. The flow control instruction may also be a front-end control instruction received by the electronic device, specifically, the electronic device presents a management interface, and presents a flow control function item in the management interface, the user may trigger a corresponding flow control operation based on the flow control function item, and the electronic device receives the flow control operation for the flow control function item, and generates the flow control instruction. And then, after receiving the flow control instruction, the electronic device adjusts the first pushing rate to a second pushing rate indicated by the flow control instruction based on the flow control instruction, and pushes the internet of things message in the target message queue at the second pushing rate. It should be understood that, the first push rate and the second push rate are both greater than or equal to 0BPS, and when the push rate is 0BPS, the internet of things message in the target message queue is not pushed. In some embodiments, the electronic device may further stop pushing the internet of things message in response to a message pushing closing instruction for the message pushing switch, so that the message pushing may be stopped during an upgrade or failure of the downstream message consumer service, the internet of things message may be cached, and the pushing may be continued after the downstream message consumer service is recovered.
In the embodiment of the application, the message of the internet of things is transferred to the target message queue, so that the target message queue can be conveniently managed to control the message flow, the rate of pushing the message to the message consumer service can be limited, and the message consumer service is helped to reduce the memory peak value.
In some embodiments, the electronic device further includes a message bus management front-end through which the user can associate the internet of things message.

The producer agent service is responsible for receiving the internet of things message generated by the message producer service of the external internet of things equipment, and writing the internet of things message into an initial message queue corresponding to the kafka message middleware according to the producer ID and the message type in the internet of things message. The message distribution service reads the internet of things message stored in the kafka message middleware by the producer agent service, determines a receiver (message consumer service) of the internet of things message through a subscription relation and a message consumer service set, generates a message copy and stores the message copy in a target message queue associated with the receiver in the kafka message middleware. The consumer proxy service is responsible for pulling the internet of things messages in the target message queue from the kafka message middleware and pushing the internet of things messages to the external message consumer service at a defined rate. The cluster management service is responsible for cluster management and node configuration of producer agent services, message distribution services and consumer agent services. In addition, the message bus management front end comprises a message subscription management front end and a cluster management front end. The message subscription management front end is used for controlling the message bus web interface service so as to manage the subscription relationship between the internet of things message and the message consumer service. The cluster management front end is used for controlling cluster management service so as to manage the Internet of things messages of the Kafka cluster, and particularly manages producer agent service, message distribution service and consumer agent service, so that management of an initial message queue and a target message queue in the Kafka cluster is realized. The message bus service provided by the embodiment of the application supports horizontal expansion and cluster deployment, and has high availability and high expansibility.

The electronic device responds to the configuration operation aiming at the message configuration interface, and obtains the corresponding relation between the configured message type and the message consumer service. Here, the correspondence between the message type and the message consumer service is used for the message distribution service to determine the message consumer proxy service corresponding to the internet of things message based on the message type of the internet of things message read from the initial message queue, thereby determining a target message queue of the determined message consumer proxy service to add the internet of things message to the target message queue.
According to the method and the device, the message bus service is added between the access service and the upper layer business processing service, the generation and consumption of the message of the Internet of things are decoupled, the message bus service performs unified processing, the development efficiency of the message processing system of the Internet of things is improved, the message of the Internet of things is transferred and stored between two message queues (an initial message queue and a target message queue), a front-end interface is provided for a user to configure the subscription relation between the message of the Internet of things and the message consumer service, the pushing rate of the message of the Internet of things is controlled, and the message of the Internet of things is managed more flexibly. In addition, a unified interface is provided for configuration management of the internet of things messages, and operation management of users can be more convenient, visual and simple.

Here, the preset rule may be implemented by a rule engine. Exemplarily, referring to fig. 11, fig. 11 is an alternative architecture diagram of a message processing system of the internet of things provided by the embodiment of the present application. According to the method and the device, the capability of screening, processing and forwarding the internet of things messages according to the rules can be provided through the rule engine service, the user can customize the preset rules of data screening, the preset rules of data format conversion or the preset rules of message forwarding, so that the internet of things messages matched with the rules can be screened and then sent to the message consumer service, or the internet of things messages are subjected to format conversion and then sent to the message consumer service, or the internet of things messages are forwarded to other back-end services, and more services are obtained to process the internet of things messages. In the embodiment of the application, the rule engine supports screening and filtering of the internet of things messages according to the message types and the attribute values, and then sends the processed internet of things messages to corresponding destinations.
