Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to Fig. 1, the invention provides case change measure and control device ethernet ring network communication is realized in a kind of new energy power station to be
System, it includes the ring communication network for becoming measuring and controlling equipment 20 by looped network sink devices 10 and some casees, with reference to Fig. 2 and Fig. 3：
Looped network sink devices 10 include：
First message process unit 11, for packet parsing and response processing；
First message transmissions unit 12, for message to be sent or received according to the instruction of the first message process unit 11；
The network control unit 14 of first network control unit 13 and second, for respectively to two biographies of ring communication network
Defeated direction sends message, or receives the message that the transmission of ring-type communication network both direction comes.
Case, which becomes measuring and controlling equipment 20, to be included：
Second message process unit 21, for packet parsing and response processing；
Second message transmissions unit 22, for message to be sent or received according to the instruction of the second message process unit 21；
Ethernet transmission unit 23, divide for receiving the network control unit 14 of first network control unit 13 and second
The message not sent.
In embodiments of the invention, outside the division ring net communication port of looped network sink devices 10, single communication port and station are also configured
Interior complex automatic system connection.
With reference to Fig. 2A and Fig. 2 B, so that 1# casees become measuring and controlling equipment as an example, case becomes the message R1 that measuring and controlling equipment 20 is sent, and passes through
A, two looped network communication ports of B are sent to both direction simultaneously, and A mouth messages R1-A is sent directly to looped network sink devices 10B mouths, B
Mouth message R1-B is sent to the A mouths of looped network sink devices 10 after looped network other casees change observing and controlling.
The message R2 sent for looped network sink devices 10, it is same by two looped network communication ports of A, B of looped network sink devices
When to both direction send, B mouth messages R2-B be sent directly to 1# casees become observing and controlling A mouths, A mouth message R2-A are through other casees of looped network
Sent after becoming observing and controlling to 1# casees change observing and controlling B mouths.
The looped network communication port of looped network sink devices 10 is using two independent ethernet controller (corresponding first network controls
The network control unit 14 of unit 13 and second).Equipment CPU simultaneously receive two ethernet controllers of looped network message R1-A,
The the first message transmissions unit 12 run on R1-B, CPU carries out filtration treatment to message, and two messages of R1-A, R1-B are merged
After a message R1', the parsing of message is completed by the first message process unit 11, response is handled.When sending message, message hair
Send application program by message R2 ' and meanwhile be sent to looped network first network control unit 13 and the second network control unit 14 two with
Too net controller, two messages of R2-A and R2-B are sent to the both direction of looped network simultaneously.
In conjunction with Fig. 3 A and Fig. 3 B, the inside of Ethernet transmission unit 23 that case becomes measuring and controlling equipment 20 uses Ethernet exchanging core
Piece realizes three port ethernet functions of exchange, wherein 2 communication ports are looped network communication port, 1 communication port and CPU ether in addition
Net controller connects.Message R2-A, R2-B that two looped network communication ports receive are after Ethernet switching chip while reach
The message run on CPU, CPU receives application program and carries out filtration treatment to message, and it is logical with equipment itself to filter out destination address
Interrogate the unmatched message in address, and by address match two messages of R2-A, R2-B merge into a message R2' after, by message
Handle application program and complete the parsing of message, response processing.Meanwhile the message R2-B that receives of looped network Ethernet A controllers pass through with
Too after net exchange chip, it can be retransmited from looped network Ethernet B controllers to looped network；The report that looped network Ethernet B controllers receive
Literary R2-A can be retransmited to looped network after Ethernet switching chip from looped network Ethernet A controllers.When sending message, message
Send application program and message R1 ' is sent to CPU ethernet controllers, looped network A, B two is sent to simultaneously after exchange chip
Ethernet controller, two messages of R1-A and R1-B are sent to the both direction of looped network simultaneously.
The present invention provides accordingly realizes that case becomes observing and controlling dress in a kind of new energy power station realized by system as described above
The method for putting ethernet ring network communication, this method include：
First message forwarding step：Looped network sink devices 10 are decomposed into two strips by after packet parsing processing to be sent
Message is separately sent to ring communication network；
First message receiving step：Looped network sink devices 10 receive the message that the transmission of ring-type communication network both direction comes,
And parse and respond after carrying out merging treatment；
Second message forwarding step：Case becomes measuring and controlling equipment 20 by after packet parsing processing to be sent, is decomposed into two strips
Message is separately sent to ring communication network；
Second message receiving step：Case becomes measuring and controlling equipment 20 and receives the message that the transmission of ring-type communication network both direction comes,
And parse and respond after carrying out merging treatment.
In summary, the present invention includes becoming the loop network of measuring and controlling equipment by looped network sink devices and some casees, and looped network converges
Collection equipment includes：First message process unit, for packet parsing and response processing；First message transmissions unit, according to
The instruction of one message process unit sends or received message；First network control unit and the second network control unit, for
Ring communication network sends message, or receives the message that the transmission of loop network both direction comes；Case, which becomes measuring and controlling equipment, to be included：Second
Message process unit, packet parsing and response are handled；Second message transmissions unit, according to the instruction of the second message process unit
Send or receive message；Ethernet transmission unit, sent for receiving first network control unit and the second network control unit
Message.Whereby, the beneficial effect that invention is created is that case, which becomes in observing and controlling, need not use professional ring exchanger factory
The switching equipment and looped network agreement, system of family need not configure ring exchanger equipment, substantially reduce and realize that case becomes observing and controlling looped network
The cost of communication.During other engineering debugging, it is not necessary to swap the looped network configuration work of machine, effectively reduce engineering debugging difficulty
And the time.The switching problem of looped network communication is also not present simultaneously.When a certain equipment fault or communication optical fiber disconnect, equipment in looped network
The redundant message of transmission is changed into one direction transmission, and all communication functions can still normally complete, without any switching time.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
Know those skilled in the art when can be made according to the present invention it is various it is corresponding change and deformation, but these corresponding change and become
