Abstract

A PLC controller with dual CPU comprises a remote cabinet 5 and a main-control cabinet 3, wherein a CPU 9 is arranged inside the remote cabinet 5, a CPU 10 is arranged inside the main-control cabinet 3, and the CPU 9 is connected with the CPU 10. Upon a communication failure, the CPU 9 under the master mode sends a command of 'disconnecting the power network 7' to an inverter 6, the CPU 10 under the slave mode draws the conclusion of the communication failure and sends out a command of full feathering and a command of stopping yawing to stop the machine for protecting the equipment, then the CPUs 9 and 10 continue to detect the communication signal until the recovery of the communication. The PLC controller has the characteristics of high machine productivity, safety and reliability.

Description

The PLC controller that has two CPU
Technical field
The utility model relates to a kind of PLC controller, especially a kind of PLC controller that has two CPU.
Background technology
Along with the raising of environmental protection and energy saving consciousness, the development of wind power plant is extremely rapid in recent years.All use Programmable Logic Controller (Programmable LogicController in the wind generator system, be called for short PLC) control, according to the control requirement, the function that system institute should have has: the abort situation audit function of self-diagnostic function, module, bus data transmit audit function, hardware and software failure audit function and other essential self-diagnostic function of failing.System should have special fault diagnosis picture to show to carry out the fault eliminating.After the short-term power interruption, system can keep its repertoire.When long term power source was interrupted, system still can be closed to the safe condition of predesignating, and keeps its last parameter tuning value and configuration etc.Should be able in 30 seconds, start automatically in system behind the power up, and make it be in state that operating personnel predesignate, rational.
Existing wind-driven power generation control system; the master-salve station that all adopts mainframe and extension frame and single CPU and remote communication module to form is controlled, if communication failure takes place, the PLC controller is according to intrinsic working method; can transfer stopped status to, reduce the security and the fiduciary level of system.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art; a kind of PLC controller that has two CPU is provided; can make controller under the situation that communication failure takes place; automatically perform safety precautions and report to the police, have high efficiency, safe and reliable characteristics to remote control center.
To achieve these goals, the technical solution adopted in the utility model is: a kind of PLC controller that has two CPU, include long-range cabinet 5 and master control cabinet 3 compositions, and be provided with CPU9 in the long-range cabinet 5, be provided with CPU10 in the master control cabinet 3, CPU9 is connected with CPU10.
Described long-range cabinet 5 is arranged in the machine tower 4.
Described master control cabinet 3 is arranged in the cabin 2.
Described CPU9 is connected with CPU10 by PROFIBUS-DP bus 12.
Described PROFIBUS-DP bus also is provided with a touch-screen 11.
Described CPU9 is made as slave station mode.
Described CPU10 is made as master station mode.
The utility model has the following advantages owing to adopted the dual-cpu structure control idea:
One, system works efficient height: two CPU control, two main websites have relatively independent decision-making and executive capability, between carry out system monitoring by exchanges data, realize the high-efficiency operation of system.
Two, security of system and reliability height: detect by communication failure, reach the purpose that the system failure is reported to the police, and after communication failure takes place, carry out the tie-in outage homing action according to setting, the protection system hardware device.
Therefore, the utility model high efficiency, safe and reliable, and blower fan system had excellent control effect.
Description of drawings
Fig. 1 is a PLC structural representation of the present utility model.
Fig. 2 is a device location synoptic diagram of the present utility model.
Fig. 3 is the utility model workflow diagram, and wherein Fig. 3 (a) is the workflow diagram of master station mode CPU9; The workflow diagram of Fig. 3 (b) slave station mode CPU10.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in further detail.
Referring to Fig. 1,2, a kind of PLC controller that has two CPU, comprise organic tower 4 and the cabin 2 that is arranged on machine tower 4 tops, one end in cabin 2 is provided with wheel hub 13, be provided with in the wheel hub 13 and become oar servomotor 1, be provided with long-range cabinet 5 in the machine tower 4, be provided with CPU9 in the long-range cabinet 5, long-range cabinet 5 is connected with remote control center 8 and inverter 6, inverter 6 links to each other with electrical network 7, be provided with master control cabinet 3 in the cabin 2, be provided with CPU10 in the master control cabinet 3, CPU9 is connected with CPU10 by PROFIBUS-DP bus 12, PROFIBUS-DP bus 12 also is provided with a touch-screen 11, CPU9 is made as slave station mode, and CPU10 is made as master station mode, but by carrying out blocked operation between touch-screen 11 main websites and the slave station.CPU9 mainly be responsible for to receive the related data of CPU10, and sends the be connected to the grid orders of 7 actions of inverter 6, and keeps communicating by letter with remote control center 8; CPU10 mainly is responsible for receiving the related data of CPU9, and controls the normal operation of generator, yaw motor, change oar servomotor 1.
Referring to Fig. 3, when operate as normal, as detect communication failure, master station mode CPU9 sends the order that breaks away from electrical network 7 to inverter 6 behind communication failure, and reports to the police; After slave station mode CPU10 draws the communication failure conclusion, send feathering order, orderly closedown order to servomotor 1, protection equipment, CPU9, CPU10 can continue to detect signal of communication afterwards, and be normal up to communication recovery.
Principle of work of the present utility model is:
Behind communication failure, after CPU9 in the long-range cabinet 5 receives the related data of the CPU10 transmission in the master control cabinet 3 by PROFIBUS-DP bus 12, send the order that breaks away from electrical network 7 to inverter 6, and keep communicating by letter with remote control center 8, after CPU10 in the master control cabinet 3 receive the related data that CPU9 sends by PROFIBUS-DP bus 12, and the normal operation of control generator, yaw motor, change oar servomotor 1.
