Abstract
The invention relates to a control module applied to a control network. The control module comprises an interface circuit used for realizing communication with external equipment, a communication device which is configured to communicate with the external equipment through the control network by the aid of communication with the interface circuit, a coupling device which is configured to mechanically couple the control module with an adjacent control module and provide data connection between the communication device and the adjacent module, and electrical isolation in data connection between the communication device and the coupling device.
Description
Technical field
The present invention relates to, but not limited in communication module, communication component and communication network such as industrial control condition
The realization of control module, control assembly and controlling network.
Background technology
Transmission of the communications applications such as Industry Control Application for signal of communication in a communication network is probably severe
Environment.This is partially due to electromagnetic noise amount in environment.Therefore, the communication of signal of communication is transmitted by it
Agreement and transmission medium generally have to be robust, so as to the Latent destruction shadow of electromagnetic interference can be born
Ring.The signaling technology of transimission power high or elasticity is generally needed to the communication of such noise robustness.In addition,
In some environment, the distance of signal of communication covering is probably big, and this is to the communication in industrial control condition
The realization of network brings further limitation.
Industrial control condition is typically implemented communication network such as controlling network, its node for including can serve as network
A large amount of control modules.In some controlling networks, some nodes are away from other nodes, and other nodes are tight
It is close closely to flock together.Close proximity placed for example with to specific equipment in some modules or node
Measure or to its transmission of control signals or in order to carry out other actions in the case of, related module also may be used
To be mechanically coupled to each other.The cost of controlling network is realized to reduce, generally communication is divided into using different
The part of agreement.First agreement can be used for the telecommunication being normally filled with the environment of noise, and different
The communication that is used between the module that flocks together of the second communication protocol.
Because second protocol is generally operated between the module being mechanically coupled in relatively good environment, institute
Can be agreement simpler than the first agreement or less robust with second protocol.Second protocol and the first agreement
Difference can be that packet configuration and/or physical layer property are differed with the first agreement.Therefore,
Displacement node in controlling network can be communicated using the first agreement, and the group of the node in controlling network
Group can discretely be communicated with one another using second protocol.Such arrangement needs protocol conversion circuitry with first
Changed between agreement and second protocol.However, protocol conversion circuitry be typically required external electric power and
The active circuit of signal transacting, which increases power needs, cost and the complexity of controlling network realization, and
And be also possible to increase treatment delay to communication.This real-time or certainty for fast-acting may be needed
Communication industrial control condition for it is particularly disadvantageous.
The communication in following controlling network is needed to realize：It is wherein negative in the validity generation not to network service
Reduces cost and complexity in the case of face sound.
The content of the invention
The invention provides a kind of control module for being used in controlling network, the control module includes：
Interface circuit, for realizing the communication with external equipment；Communicator, is configured to by means of electric with interface
Road communication passes through controlling network and external device communication；Coupling device, is configured to control module mechanically
It is coupled to adjacent control module and the data cube computation between communicator and adjacent module is provided；And
The electric isolution in data cube computation between communicator and coupling device.
By providing the coupling for including being configured to be mechanically coupled to control module adjacent control module
The control of the electric isolution in device and the data cube computation between communicator and the coupling device of communication module
Molding block, can be adversely affected using only single communication protocol with the operation not to each communication module
Cost-effective mode come realize the communication between module such as control communication.By in specific communication module
There is provided between coupling device and communicator and isolated, reduced by the noise current amount of communicator.Communication
The isolation of module not only isolates communicator with the other elements of communication network, also prevents connecing for communication module
Operation of the noise current caused in mouth circuit to communicator is adversely affected.
This is especially advantageous in only with the communication network of single communication protocol because be arranged on coupling device with
Isolation between communicator can in some way be specified by communication protocol.And, these features are caused
Can be realized using single unified communication protocol the deployment of communication network such as controlling network without
Other and sizable isolation is disposed in communication module.
By providing the ability, because all elements use the other elements identical communication protocols with communication network
View, so also there is no need to perform protocol conversion in communication component such as control assembly.It is thereby achieved that
The module that will be mechanically coupled to is integrated into communication network without the second communication protocol and protocol converter.
Because, in the case where not adversely affected to the operability of modules, by interface electricity
The communication that connection simplifies the robust in the communication module being mechanically coupled to is provided between road and communicator
The realization of agreement.
Specific embodiment
The invention provides a kind of control module for being used in controlling network, the control module includes：

It is coupled to adjacent control module and the data cube computation between communicator and adjacent module is provided；And
The electric isolution in data cube computation between communicator and coupling device.
Include being configured to filling the coupling that control module is mechanically coupled to adjacent control module by providing
Put and the data cube computation between communicator and the coupling device of communication module in electric isolution control
Module, can using only single communication protocol with the operation not to each communication module adversely affect into
This effective manner come realize the communication between module such as control communication.By the coupling in specific communication module
There is provided between connection device and communicator and isolated, reduced by the noise current amount of communicator.Communication mould
The isolation of block not only isolates communicator with the other elements of communication network, also prevents the interface of communication module
