Technical field
The present invention relates to loop network control technology fields, in particular to the structure based on loop network control technology.
Background technique
Traditional networking mode is needed by carrying out data exchange, and the Profibus communication of bottom between heterogeneous networks layer
It is easy to be influenced by communication distance and website quantity, transmission rate, efficiency are not high enough, embody in present large-scale performance
The synchronism and stability come are lower, are not able to satisfy the demand of high-end performance instantly.
Summary of the invention
Place that purpose of the invention is to overcome the shortcomings in the prior art, it is simple to provide a kind of structure, and user
Just the structure based on loop network control technology,.
In order to achieve the above object, the present invention uses following scheme：
A kind of structure based on loop network control technology includes host computer and Ethernet switch, described upper
Communication connection between machine and Ethernet switch, it is characterised in that：Redundancy loop network is equipped with by the Ethernet switch
Control system, communication connection between the Ethernet switch and redundancy ring networked control system.
A kind of structure based on loop network control technology as described above, it is characterised in that the redundancy loop network control
System includes the CPU there are two redundancy, driving/I/O module group and executing agency is equipped between the CPU of the redundancy, wherein one is superfluous
Remaining CPU and driving/I/O module group communication connection, the communication connection of the driving/between I/O module group and executing agency are another superfluous
Communication connection between remaining CPU and executing agency.
A kind of structure based on loop network control technology as described above, it is characterised in that the driving/I/O module group packet
Multiple driving/I/O modules, communication connection between adjacent driving/I/O module are included.
A kind of structure based on loop network control technology as described above, it is characterised in that the executing agency includes more
A execution module, communication connection between adjacent execution module.
In conclusion the present invention compared with the existing technology the beneficial effect is that：
The present invention is by can be with a net on earth, from host computer to bottom by the redundancy ring networked control system of Ethernet
Driving executing agency is used uniformly a kind of Profinet communication modes, does not need to carry out the data exchange between different stratum reticulares, improves
Communication efficiency and communication speed, and rate adaptation can be carried out according to the synchronization of different occasions and real-time requirement, really realize
The demand for control of real-time communication RTReal Time and synchronous real-time communication IRTIsochronous Real Time, while can group
The website built becomes more the network station points by the net-working standard of international Ethernet, in same network segment as no more than 255
A, the communication distance between website is also farther compared with Profibus communication modes, the stability and security performance of the control system
Higher, if one of CPU is damaged, the switching of Millisecond is may be implemented in another CPU, to guarantee control task
It smoothly completes, these are all that traditional control method institute is incomparable.
