Abstract
The present invention comprises a communication module. A communication module used in a control network comprises: an interface circuit configured to realize communication with an external device; a communication device configured to communicate with the external device through the control network by means of communication with the interface circuit; a coupling device configured to mechanically couple the control module to an adjacent control module and provide data connection between the communication device and the adjacent module; and an electrical isolation in data connection located between the communication device and the coupling device.
Description
Technical field
The present invention relates to, but not limited to the control module in communication module, communications component and communication network such as industrial control condition, control assembly and control the realization of network.
Background technology
Communications applications such as Industry Control Application is probably rugged environment for signal of communication transmission in a communication network. This is partially due to electromagnetic noise amount in environment. Therefore, the Latent destruction impact of electromagnetic interference generally has to be robust by the communication protocol of its transmission signal of communication and transmission medium, thus can be born. The communication of such noise robustness is typically required high through-put power or elastic signaling technology. It addition, in some environment, the distance that signal of communication covers is probably big, and the realization of the communication network in industrial control condition is brought further restriction by this.
Industrial control condition is typically implemented communication network as controlled network, it include can serve as network node control module in a large number. Controlling in network at some, some nodes are away from other nodes, and other nodes close proximity flock together. Close proximity placing such as with to the measurement of specific equipment or to its transmission of control signals or in order to carry out other actions in some modules or node, relevant module can also mechanically be coupled to each other. In order to reduce the cost realizing controlling network, generally communication is divided into the part using different agreement. First agreement may be used for the telecommunication being normally filled with in the environment of noise, and different second communication agreements is used for the communication between the module flocked together.
Because second protocol generally operates between the module being mechanically coupled in relatively good environment, so second protocol can be the agreement simple or more less robust than the first agreement. The difference of second protocol and the first agreement can be in that, packet configuration and/or physical layer character differ with the first agreement. Therefore, the displacement node controlled in network can use the first agreement to communicate, and the group controlling the node in network can use second protocol to communicate with one another discretely. Such layout needs protocol conversion circuitry to change between the first agreement and second protocol. But, protocol conversion circuitry is typically required the active circuit of external electric power and signal processing, which increases the power needs, cost and the complexity that control real-time performance, and also is likely to process to communication increase postpone. This is particularly disadvantageous for the industrial control condition of the real-time or deterministic communication being likely to need fast-acting.
The following communication controlled in network is needed to realize: wherein in the situation decline the low cost effectiveness of network service not being had a negative impact and complexity.
Summary of the invention
The invention provides a kind of control module for using in controlling network, this control module includes: interface circuit, for realizing the communication with external equipment; Communicator, be configured to by means of with interface circuit communication by controlling network and external device communication; Coupling device, is configured to be mechanically coupled to adjacent control module by controlling module and provide the data cube computation between communicator and adjacent module; And it is in the electric isolution in the data cube computation between communicator and coupling device.
By providing the control module included being configured to by controlling coupling device that module is mechanically coupled to adjacent controls module and the electric isolution that is in the data cube computation between communicator and the coupling device of communication module, it is possible to only use single communication protocol by the operation of each communication module is not adversely affected cost-effective in the way of realize between module communication such as control to communicate. By providing isolation between the coupling device and communicator of specific communication module, decrease the noise current amount by communicator. The isolation of communication module, not only by other element separation of communicator Yu communication network, also prevents the noise current caused in the interface circuit of communication module from the operation of communicator being adversely affected.
This is especially advantageous in the communication network only with single communication protocol, because the isolation being arranged between coupling device and communicator can be specified in some way by communication protocol. And, these features make it possible for single unified communication protocol to realize communication network as controlled the disposing without disposing other and sizable isolation in communication module of network.
By providing this ability, because all elements use the communication protocol identical with other elements of communication network, so also without necessity at communications component as controlled to carry on an agreement in assembly conversion. It is thereby achieved that the module being mechanically coupled to is integrated in communication network without second communication agreement and protocol converter. This is because, when the operability of modules not being adversely affected, by providing the realization of the communication protocol being connected the robust simplified in the communication module being mechanically coupled between interface circuit with communicator.
