Abstract
A wind power generation control device with a soft redundancy function comprises a main CPU module, wherein the DP communication port of the main CPU module is respectively connected with the DP communication ports of a slave CPU module, a monitor terminal and a distributed input/output module through a data bus; the DP communication port of the slave CPU module is connected with the DP communication port of the distributed input/output module through the data bus; when in the normal operation of the system, the two CPU modules can normally complete the respective work, communicate with each other, and adjust whether the respective one is under the normal operation condition or not through the contrast way by a software, once one CPU module fails, the other CPU module can play the relative control function of the CPU module, so the utility model has the characteristics of high working efficiency of the complete device, good system safety and improved maintainability.
Description
Technical field
The utility model belongs to a kind of wind power generation controlling device, particularly possesses the wind power generation controlling device of soft redundancy feature.
Background technique
In industrial automation system; move reliably in order to make system's long-term stability; all use controller to control in the wind-power generating system; usually adopt a master controller to control; in case but this master controller is when breaking down, unit can enter the emergency shutdown state, can't work on; influenced the working efficiency and the economic benefit of whole unit, the Security of system and reliability are not high.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model has been to provide the wind power generation controlling device that possesses soft redundancy feature, has complete machine high working efficiency, good, the maintainable characteristics that improve of security of system.
To achieve these goals, the technical solution adopted in the utility model is:
The wind power generation controlling device that possesses soft redundancy feature, comprise a host CPU module, the DP PORT COM of host CPU module is connected with DP PORT COM from CPU module, monitor terminal and distributed input/output module respectively by data/address bus, is connected with the DP PORT COM of distributed input/output module by data/address bus from the DP PORT COM of CPU module.
Monitor terminal can be realized the host CPU module and from the principal and subordinate's handover operation between the CPU module.
Because the utility model is provided with the host CPU module and from the CPU module, have complete machine high working efficiency, good, the maintainable characteristics that improve of security of system.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a CPU module operational flow diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are described in further detail.
With reference to Fig. 1, the wind power generation controlling device that possesses soft redundancy feature, comprise a host CPU module 4, the DP PORT COM of host CPU module 4 is connected with DP PORT COM from CPU module 5, monitor terminal 6 and distributed input/output module 7 respectively by data/address bus 8, is connected with the DP PORT COM of distributed input/output module 7 by data/address bus 8 from the DP PORT COM of CPU module 5.Can realize host CPU module 4 and from the principal and subordinate's handover operation between the CPU module 5 by monitor terminal 6, the DP PORT COM of host CPU module 4 is by data/address bus 8 and the data communication that realizes two CPU modules from the DP PORT COM of CPU module 5.
With reference to Fig. 2, by host CPU module 4 with formed soft redundant wind-power electricity generation controller from CPU module 5 with two CPU modules.Two CPU modules are all normally finished work separately when system normally moves, and both intercom mutually, and judge by the software way of contrast whether the other side is in normal working, in case certain CPU module breaks down, another CPU module is with the relevant control function of taking over fault CPU module.In the unit normal course of operation, make mistakes even without any assembly, operator also can realize manual master-slave cpu module switching by monitor terminal 6.
Working principle of the present utility model is:
When software redundancy system carries out work, host CPU module 4 and are independent operatings from CPU module 5, by the control that host CPU module 4 is grasped distributed input/output module 7, host CPU module 4 and the program from CPU module 5 are formed by nonredundancy program and redundant program.
When a CPU module of wind-driven power generation control system breaks down, another CPU module is judged the other side's fault state immediately by the data way of contrast, the CPU module of kilter will enter the Redundant Control pattern, all of taking over fault CPU module are controlled functions rapidly, realize CPU module handover mechanism, and report to the police to operator, avoid system out of service or more major break down takes place.After the switching of CPU module was finished, the CPU module of kilter was carried out control task with last complete synchronous data as the basis.The function that the CPU module principal and subordinate of software redundancy system is switched has improved the reliability of wind-power generating system, has realized the control function of system preferably.
Claims (1)
