Example 1
Referring to fig. 1-4, a method for a device to connect to message middleware includes the steps of:
step 1: the method comprises the steps that a cloud platform receives an activation request sent by equipment, and the cloud platform stores addresses of a plurality of message middleware and records the number of equipment connected with each message middleware; the record of the number of devices to which the message middleware is connected is updated each time a message middleware is assigned to a device.
The message middleware of the present invention is typically an ActiveMQ message middleware, but does not exclude other types of message middleware such as RabbitMQ, Kafka, RocketMQ, etc.
The activation request sent by the equipment comprises the ID of the equipment, and the ID of the equipment, an account number and a password which are allocated to the equipment are stored in the cloud platform in advance; and (5) after the cloud platform receives the activation request, performing step 2.
Step 2: distributing a message middleware for the equipment and sending the address of the message middleware to the equipment; the device is connected with the corresponding message middleware through the address and is in communication connection with the cloud platform through the message middleware.
One alternative strategy for assigning a message middleware to a device is: and selecting the message middleware with the least number of connected devices to be distributed to the devices according to the number of the connected devices on each message middleware.
But other strategies may be chosen, such as:
1. assigning according to a proportion of the weights
2. Random allocation
3. Allocation according to a polling algorithm
The equipment is connected with the message middleware through the address of the message middleware, wherein the authentication process is involved, and the authentication process can refer to CN 202010861045.3; the method includes that the equipment writes an account number and a password of the equipment into connection request information and sends the account number and the password to message middleware corresponding to the address, the message middleware generates an authentication request and sends the account number and the password in the authentication request and the connection request information to a cloud platform, the cloud platform authenticates the authentication, and after the authentication is passed, the message middleware and the equipment are connected.
The method for the device to connect the corresponding message middleware through the address comprises the following steps:
the device sends the connection request to the message middleware through the address; the connection request comprises an account and a password which are allocated to the equipment by the cloud platform;
in the process of registering the equipment to the cloud platform, the cloud platform generates an account and a password aiming at the equipment;
when the device sends an activation request, the cloud platform sends the address of the message middleware and simultaneously sends the account number and the password to the device.
The message middleware generates an authentication request and sends the authentication request, the account and the password to the cloud platform;
the cloud platform authenticates the account and the password according to the authentication request; the connection authentication operation may refer to fig. 6;
if the cloud platform deletes the account and the password of the device stored in the cloud platform, the authentication of the cloud platform fails, and the device cannot be connected with the message middleware. Delete device operation may refer to fig. 7.
In general, the device is a message producer and the cloud platform is a message consumer.
In the operation process, the equipment and the message middleware normally communicate, when the equipment cannot establish communication connection with the message middleware distributed by the cloud platform, the message middleware is indicated to have a fault, and the equipment sends an activation request to the cloud platform at this time.
At this time, the cloud platform executes step 1 and step 2 to reassign a message middleware to the device.
The device is connected with the ActiveMQ middleware through MQTT, and needs to be identified through three-way handshake of TCP protocol and response code of MQTT protocol:
TCP three-way handshake fails to establish connection, it means ActiveMQ is unavailable
If the TCP has established a connection, if the response code passing through the MQTT protocol is not 0x00, the connection cannot be established, the error code of 0x04 (which may occur in the case where the cloud platform deletes the account and the password of the device) may immediately restart the activation process, and if the other error codes are rejected, the connection may be tried many times, and if the connection is not successful, the activation process may be restarted.
The response code is as follows:
Figure BDA0003214079080000061
when the device is removed from the cloud platform, the cloud platform will disconnect the device by accessing the ActiveMQ through jmx.
In the embodiment, tens of thousands of devices are loaded through a plurality of ActiveMQs, the resources of the ActiveMQs are allocated by the platform according to rules, and the forwarding processing of messages is not required by an agent layer, so that the devices in the whole Internet of things system can be in the optimal communication state.
