It is connected with Star Network structure with the network switch.
After any GOOSE network recovers communication in the double nets of the GOOSE of redundancy, GOOSE links chain rupture alarm eliminates, and handle
GOOSE links chain rupture alarm eliminates signal and passes backstage on the net by the way that MMS monitoring is double.
The beneficial effects of the invention are as follows：
After using the above scheme, site workload can be mitigated, improve construction efficiency, and can guarantee that interlock alarm data transfer
Reliability and real-time.The double nets of redundancy GOOSE and the double nets of redundancy MMS monitoring use Star Network structure and the network switch
It is connected, no-harass switch can be realized between each pair of net.
Brief description of the drawings
Fig. 1 is a kind of embodiment schematic diagram of the Industry Control interlocking method based on multiplex network of the present invention；
Fig. 2 is the schematic diagram that GOOSE of the present invention retransmits communication mechanism.
Embodiment
Technical solution of the present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that ability
The technical staff in domain can be better understood from the present invention and can be practiced, but illustrated embodiment is not as the limit to the present invention
It is fixed.
A kind of Industry Control interlocking method based on multiplex network, includes the following steps：
Step 1, the double nets of GOOSE and the double nets of MMS monitoring for establishing redundancy, GOOSE network is a part of IEC61850, is responsible for dynamic
Make the transmission of signal, MMS（Manufacturing Message Specifcation：One defined in ISO/IEC9506 standards
Communication protocol of the set for industrial control system）Monitoring network be used to supporting under computer integrated manufacturing system environment programmable device it
Between bi-directional communicate.
Industrial measurement and control device（The PCS-9115 of the auspicious relay protection in south）It is respectively connected to using independent network interface card by interchanger
The double nets of GOOSE and the double nets of MMS monitoring, i.e., all industrial measurement and control devices had not only connected the double nets of GOOSE, but also the double nets of connection MMS monitoring.Such as
Shown in Fig. 1, by taking access control system and fire-fighting system in intelligent substation auxiliary system as an example, two system installation region distances compared with
Far, information exchange is carried out by the double nets of GOOSE and the double nets of MMS monitoring respectively.
Step 2, industrial measurement and control device carry out the transmitting-receiving of GOOSE message by the double nets of GOOSE, are carried out using GOOSE agreements
The transmission and control of signal, wherein, GOOSE is a kind of communications protocol based on retransmission mechanism, is all included in each frame message
" message maximum delay time " parameter, this parameter represent the maximum delay time of next frame message arrival, if more than " message
Maximum delay time " does not still receive next frame message, is judged as GOOSE link chain ruptures.Network load is overweight in order to prevent
In the case of cause the loss of GOOSE message, therefore use the mechanism that GOOSE message is retransmitted to ensure the reliable of data transfer
Property.5 frame messages are continuously transmitted using the interval of 1ms, 1ms, 2ms, 4ms, 8ms when GOOSE message is transmitted, if this variable exists
Do not change in the ensuing time, then the transmission data with 5s gap periods；If this variable changes, from during change
At quarter, sent immediately with the interval of 1ms, 1ms, 2ms, 4ms, 8ms again.It is as shown in Figure 2 that GOOSE retransmits formula communication mechanism.
Each GOOSE message is provided with unique coding, and same GOOSE message data are carried out through the double nets of GOOSE respectively
Transmission, and the GOOSE message industrial measurement and control device of identical coding only receives one, avoids the repetition of message data from receiving.
Step 3, industrial measurement and control device carry out the detection of GOOSE network break-make and interrelated logic judges：
After GOOSE pairs of net channel link all chain ruptures are detected, double nets are monitored by MMS and send GOOSE link chain rupture reports to backstage
Alert, otherwise, industrial measurement and control device exports corresponding signal by parsing GOOSE message, and is realized by Logical Configuration and correspond to
The action of mouth.GOOSE communication links are built upon on the basis of the double nets of redundancy, and single network failure does not interfere with GOOSE message
Transmission, the double network data delivery of energies of GOOSE enough realize no-harass switch.Wherein, the double nets of MMS monitoring carry out routine under normal circumstances
Monitoring, after all chain rupture of the double net channel links of GOOSE, the chain rupture of GOOSE links is sent to backstage by multiplexing technology and is alarmed.
It is preferred that the industrial measurement and control device uses ARM+DSP dual core processors：The double Netcoms of MMS monitoring are carried out in ARM sides
The alarm signal of industrial measurement and control device, is uploaded backstage by news；GOOSE communication interfaces are provided in DSP sides, send and receive GOOSE
Message, and carry out corresponding GOOSE communication links logic judgment.
The double nets of redundancy GOOSE are connected using Star Network structure with the network switch, and the double nets of redundancy MMS monitoring also use star
Type network structure is connected with the network switch, and no-harass switch can be realized between each pair of net.When any in the double nets of the GOOSE of redundancy
After GOOSE network recovers communication, GOOSE links chain rupture alarm eliminates, and GOOSE links chain rupture alarm is eliminated signal and is passed through
The double online biography backstages of MMS monitoring, realize that correlation is patrolled on the premise of no GOOSE network chain rupture alarm signal by GOOSE network
The interlocked control collected.
After using the above scheme, site workload can be mitigated, improve construction efficiency, and can guarantee that interlock alarm data
The reliability and real-time of transmission.The double nets of redundancy GOOSE and the double nets of redundancy MMS monitoring are handed over using Star Network structure and network
Change planes connected, no-harass switch can be realized between each pair of net.On the premise of the quick, reliable request needed for interlocking is met, simplification is set
Meter, construction and installation and maintenance workload, while thus caused cost can be greatly lowered, simplify construction and easy to maintain.
It these are only the preferred embodiment of the present invention, be not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure that bright specification and accompanying drawing content are made either equivalent process transformation or to be directly or indirectly used in other related
Technical field, be included within the scope of the present invention.
