Description
Technical field
The utility model relates to a kind of control system field, in particular to a kind of Redundant Control based on Profibus network
System.
Background technique
Profibus is the standard for Fieldbus for being used in automatic technology, is that most widely used scene is total in the world
Line technology, Profibus be both suitable for the communication of automated system Yu on-site signal unit, it can also be used to be directly connected to connecing
Transmitter, actuator, transmission device and the other field instruments and equipment of mouth, are acquired on-site signal and monitor, and
It is connected with bus form instead of a large amount of transmission cables required in conventional electrical with a pair of of twisted pair, largely saves cable
Expense, also accordingly save construction debugging and system put into operation after maintenance time and expense.But in single main station failure
In the case of, whole network can be out of hand immediately.Most of existing Profibus redundancy is the redundancy to medium, such as main
Station failure, whole network can be out of hand immediately.
Utility model content
For overcome the deficiencies in the prior art, the utility model uses the technology of redundancy main station, can unrestricted choice
Profibus DP main website, main website overhaul or guarantee that data are not lost when shutting down, it is ensured that the redundancy of system is reliable, is not only suitable for
New system layout is also applied for the upgrading of old system.At low cost, switching time is short, and performance is high, highly reliable, can
Various main websites are adapted to, it is flexible strong.
The purpose of this utility model adopts the following technical scheme that realization:
A kind of redundancy control system based on Profibus network, including the monitoring master with Congration III software
Machine, DF PROFI II board, FNL gateway, PRS redundancy switch and slave station equipment, the band Congration III software
Monitoring host computer is connect with the DF PROFI II board and the FNL gateway respectively, the DF PROFI II board and described
FNL gateway is connect with the PRS redundancy switch respectively by Profibus DP cable, and the PRS redundancy switch passes through
Profibus DP cable is connect with the slave station equipment.
Further, the slave station equipment includes I/O module and underlying device.
The beneficial effect that the utility model generates
Include the monitoring host computer with Congration III software by the way of redundancy main station, is based on Profibus
The DF PROFI II board of network, FNL gateway, PRS redundancy switch and slave station equipment, can be in conjunction with actual needs monitoring
Data volume is selected using any Profibus DP main website, it is not limited to DF PROFI II board and FNL gateway, main website inspection
Guarantee that data are not lost when repairing or shutting down, it is ensured that the redundancy of system is reliable, is not only suitable for new system layout, is also applied for old
System upgrading.At low cost, switching time is short, and performance is high, highly reliable, can be adapted to various main websites, flexible strong.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
Redundancy control system based on Profibus network as shown in Figure 1, including with Congration III software
Monitoring host computer, DF PROFI II board, FNL gateway, PRS redundancy switch and slave station equipment, band Congration III software
Monitoring host computer connect respectively with DF PROFI II board and FNL gateway, DF PROFI II board and FNL gateway pass through
Profibus DP cable is connect with PRS redundancy switch respectively, and PRS redundancy switch passes through Profibus DP cable and slave station
Equipment connection.
Using FNL gateway and DF PROFI II board as Liang Ge main website, two main websites are connected to the friendship of PRS redundancy simultaneously
It changes planes, the PRS redundancy switch other end connects slave station equipment, and the slave station parameter that two main websites obtain PRS redundancy switch simultaneously is (each
Tributary address, baud rate and data volume etc.) carry out configuration and configuration parameter is consistent, a main station failure or shutdown are kept in this way
Maintenance can be run after being switched to another main website under identical parameters, be unlikely to report an error.When normal work, slave station parameter passes through DF
PROFI II board is transferred to monitoring host computer, and when DF PROFI II board breaks down, slave station parameter then passes through FNL gateway and passes
It is handed to monitoring host computer.It is low in cost, control and monitoring data are not had any problems, data are protected.Profibus DP bus
Technology, communication is reliable, and rate is fast (reaching as high as 12M/s), can at most connect 127 slave station equipments, ensure that the big of data monitoring
Capacity and scalability.The utility model main website automatic switchover time is extremely short, controls in millisecond rank, for Profibus network
It may be said that having accomplished seamless switching for cycle period, the real-time update of data is maintained, when avoiding switching in other technologies
Between it is too long, cause certain time period data dead, improve the reliability of network continuous work.
Further, master device can be replaced, and be substituted for the lower equipment of cost, or since control needs to replace
It is changed to the controller equiment with other function, mainly meets the control monitoring requirement of bottom data.In DP network, in real time
Data are monitored, for critical data, are even more important, the critical data in various application scenarios is protected not lose, are tieed up
Protect the stabilization and continuous service of whole system.
Further, such as control line system Zhong Youyige main website PLC itself, Zai Jiayige main website is needed to be monitored, it is main
It stands and overhauls or guarantee when shutting down that data are not lost, and using the embodiment of the utility model, can directly add main website, handed in conjunction with redundancy
The functional characteristics changed planes, it is ensured that the redundancy of system is reliable, and the utility model is not only suitable for new system layout, is also applied for old
System upgrading.
Further, slave station equipment includes I/O module and underlying device.I/O module and underlying device are handed over PRS redundancy respectively
It changes planes connection.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
