Description
Technical Field
The invention relates to the technical field of remote control, in particular to a remote instruction issuing method based on an MQTT protocol.
Background
In current units or companies, there may be a number of different device types, such as vending machines, card issuers, and so on. Companies provide a unified management platform to manage large batches of devices of different types. If each device establishes a network connection directly with the platform, it will bring many extra network overhead and resource loss to the platform. When a class of devices is controlled through batch management, problems such as congestion or network delay may occur based on the conventional manner.
In the existing scheme, when equipment is accessed to a platform, long connection is established between the equipment and the platform, and the platform carries out remote instruction interaction with the equipment through the established long connection channel. For each device, the platform needs to maintain a long connection, and with the large-batch access of the devices, the network overhead and operation and maintenance difficulty of the platform are increased, and a large amount of resources of the platform server are occupied and consumed. The difficulty of accessing the platform by the equipment is increased.
In the prior art, an HTTP (hyper text transport protocol) interface is called to issue an instruction, a bottom layer is based on a TCP/IP (transmission control protocol/Internet protocol), short connection is established between a platform and equipment to carry out communication, and the effects of the platform and the equipment are almost the same. However, the disadvantages of the prior art include the following:
the HTTP protocol message contains a message head and a message body, and has long message format, high bandwidth and high network overhead.
The platform controls the remote equipment through the HTTP protocol, the bottom layer establishes short connection with the equipment based on the TCP/IP protocol to communicate, and the decoupling of the connection between the platform and the equipment cannot be achieved.
The message issuing quality is poor, under the condition that the network is unstable, the message issued by the HTTP protocol may have the condition that the message is lost and can not be delivered to the equipment, and the HTTP protocol does not support a message retransmission mechanism.
Disclosure of Invention
The technical problem mainly solved by the invention is to provide a remote instruction issuing method based on MQTT protocol, which can decouple a management platform and equipment by adopting an issuing/subscribing mode through the MQTT protocol, provide real-time and reliable message service for the connected remote equipment and realize the instruction control of the equipment.
In order to solve the technical problems, the invention adopts a technical scheme that: the remote instruction issuing method based on the MQTT protocol comprises the following steps:
s1, each device is connected with an MQTT Broker and subscribes to launch Topic under own command;
s2, the IoT platform also establishes connection with the MQTT Broker, the user issues a command on the IoT platform selection device, and sends a message to the designated device command to send a Topic;
s3, after receiving the IoT platform issued message, the MQTT Broker forwards the message to a subscriber of the designated Topic;
s4, after receiving the subscription message, the device analyzes and executes the command;
s5, after the command execution is finished, the equipment sends a message to the command execution response Topic and uploads the execution result;
s6, after receiving the device publishing message, the MQTT Broker forwards the message to a subscriber of the designated Topic;
s7, executing a response Topic by an IoT platform subscription command, and analyzing an update equipment command issuing result after receiving the message;
the method provides three levels of quality of service, including at most once, at least once, and only once.
Further, when selecting the service quality at most once, the steps are as follows:
s101, a publisher is connected with an MQTT Broker and publishes a message to a designated Topic, wherein the message level is QoS 0;
s102, after receiving the message, the MQTT Broker forwards the message to a subscriber of the Topic;
s103, deleting the message by the publisher.
Further, when selecting at least one service quality, the steps are as follows:
s201, storing the message by the publisher;
s202, the publisher connects MQTT Broker and publishes a message to the designated Topic, wherein the message level is QoS 1;
s203, storing the message by the MQTT Broker;
s204, after receiving the message, the MQTT Broker forwards the message to the subscriber of the Topic;
s205, the MQTT Broker responds to the publisher and issues a message confirmation;
s206, deleting the message by the publisher;
s207, the subscriber responds to the MQTT Broker and issues a message confirmation;
and S208, deleting the message by the MQTT Broker.
Further, when only one service quality is selected, the steps are as follows:
s301, storing the message by the publisher;
s302, the publisher connects with the MQTT Broker and publishes a message to the designated Topic, wherein the message level is QoS 2;
s303, storing the message by the MQTT Broker;
s304, the MQTT Broker responds to the publisher and receives the publication;
s305, the publisher informs the MQTT Broker to release;
s306, after receiving the message, the MQTT Broker forwards the message to the subscriber of the Topic;
s307, the MQTT Broker responds to the publisher to complete the publishing;
s308, storing the message by the subscriber;
s309, deleting the message by the publisher;
s310, the subscriber informs the MQTT Broker and receives the information through publishing;
s311, the MQTT Broker responds to the subscriber and releases the subscriber;
s312, notifying a subscriber;
s313, the subscriber informs the MQTT Broker of completing the publishing;
s314, deleting the message by the MQTT Broker;
and S315, deleting the message by the subscriber.
The invention has the beneficial effects that: the invention has low cost, low bandwidth, decoupling connection between the platform and the equipment and high reliability of message release quality;
the MQTT has quite short specification, very short message header, low cost and minimized protocol exchange, so that the network flow is reduced, and low cost and low bandwidth can be realized;
the platform and the equipment are not directly connected, and a publish/subscribe message mode is adopted, so that one-to-many message publishing can be realized, and the connection coupling between the platform and the equipment is released;
compared to HTTP, the MQTT protocol ensures high transmission guarantees. There are 3 levels of quality of service:
at most once: ensuring that the message is delivered as soon as possible;
at least once: the message is guaranteed to arrive at least once. But messages may also be delivered more than once;
only once: each message is guaranteed to be received only once by the other party.
The invention is faster, more convenient to maintain, more flexible, safer and more stable.

s202, the publisher connects MQTT Broker and publishes a message to the designated Topic, wherein the message level is QoS 1;
s203, storing the message by the MQTT Broker;
s204, after receiving the message, the MQTT Broker forwards the message to the subscriber of the Topic;
s205, the MQTT Broker responds to the publisher and issues a message confirmation;
s206, deleting the message by the publisher;
s207, the subscriber responds to the MQTT Broker and issues a message confirmation;
