In the Internet of things architecture, a mode of operation of a multi-middle computer and a multi-upper computer networking is adopted, data interaction is carried out between the middle computer and the upper computer through a message middleware, wherein the middle computer is connected with functional equipment and is responsible for data acquisition, and the upper computer is responsible for functions of data processing, data floor storage and the like.
Referring to fig. 1 to 3, an internet of things networking method includes the steps of:
s1, accessing a new upper computer;
s2, acquiring the service type and/or data characteristics of each subscription topic in the message middleware and generating a service distribution rule;
and S3, controlling the original upper computer to unsubscribe the corresponding subscription theme according to the service allocation rule and controlling the new upper computer to access the corresponding subscription theme.
From the above description, the beneficial effects of the invention are as follows: the method comprises the steps of generating a targeted service distribution rule by acquiring the service type and the data characteristic of a subscription topic in a message middleware, controlling an original upper computer to unsubscribe the corresponding subscription topic according to the service distribution rule, pushing the unsubscribed corresponding subscription topic to a new upper computer, completing networking under the architecture of the Internet of things, and uniformly distributing service loads to the original upper computer and the new upper computer, so that resource waste is avoided.
In the embodiment of the present invention, the step S2 specifically includes:
And acquiring the data receiving frequency and the data magnitude of each subscription theme in the message middleware, evaluating the load degree of the original upper computer, and generating a service distribution rule according to the load degree.
According to the description, the data receiving frequency and the data magnitude of each subscription subject in the message middleware are obtained by adopting a load priority principle, the load degree of the original upper computer is estimated based on the data, and if the load of the original upper computer is too high, a service distribution rule is established for the purpose of average load, and the load is balanced to the original upper computer and the new upper computer.
In the embodiment of the present invention, the step S2 specifically includes:
And acquiring the service type of each subscription theme in the message middleware, and performing service matching according to the characteristics of the upper computer to generate a service distribution rule.
From the above description, it can be known that, by adopting a configuration priority principle, the service type of each subscription topic in the message middleware is obtained, service matching is performed according to the characteristics of the new upper computer and the original upper computer, and a service allocation rule is generated, for example, the A topic service matches the characteristics of the new upper computer, and then all the A topics are allocated to the new upper computer; preferably, in the internet of things, according to actual running conditions, a distribution rule of a service theme is preset, and load balancing is performed after networking according to the distribution rule of the preset service theme.
In an embodiment of the present invention, step S1 further includes step S0:
and accessing the new median, and controlling the new median to push data to the message middleware.
As can be seen from the above description, when the service data is too much, the central processing unit is also subjected to networking processing, the central processing unit is newly added, and the new central processing unit is controlled to push data to the message middleware; specifically, after the new central computer is accessed, the upper computer in the architecture is notified, the processing module of the central computer is initialized, the subscription theme is distributed to the new central computer, and the central computer pushes data according to the distributed main body.

The http communication mode has the problems that data interaction is slow, bidirectional interaction communication between an upper computer and a middle computer is impossible, active pushing is impossible, multicasting is impossible and the like, and the real-time refreshing of the data only depends on timing polling, so that the timeliness is low and the performance is low; although the modbus communication mode solves the problem of equipment communication timeliness, the modbus communication mode needs to occupy hardware resources, faces high complexity of protocol design and high development cost, and is difficult to realize broadcasting capability, for example, in a multi-set equipment networking, wherein certain set of equipment triggers fire safety, and other equipment needs to be informed to trigger safety protection; the socket communication mode can effectively solve the defects of communication modes such as http and modbus, but in a multi-middle position and multi-upper position networking application scene, different sockets need to be connected with each other, each socket needs to be maintained in real time and a plurality of socket communication states, and the implementation difficulty is high. Based on the problems, by introducing EMQX service components and utilizing the characteristics of the service components, the efficient interaction of data between different terminals and the safe transmission of data in a multi-medium-position machine and multi-upper-position machine use scene are realized, and the functions of networking and off-network different terminals at any time along with the subsequent expansion of the service or the increase of the service demand can be completely dealt with, so that the networking difficulty is greatly reduced, the research and development cost is reduced, and the maintenance cost is reduced.
