Problems solved by technology

In the prior art, the factory debugging of the pitch controller is that the staff use various conventional testing instruments to debug each function of the pitch controller one by one. Since it is done manually, this debugging scheme has too many human interference factors, which is difficult for The business level requirements of the commissioning personnel are relatively high, and the automatic and batch commissioning of the pitch controller cannot be realized
When the production task is heavy, it will seriously restrict the factory quantity of the controller, thereby affecting the production of the pitch system, which is the bottleneck of the mass production of the entire fan pitch system

Embodiment Construction

[0065] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0066] Any feature disclosed in this specification, unless specifically stated, can be replaced by other alternative features that are equivalent or have similar purposes. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0067] Such as figure 1 , The pitch controller disclosed in the present invention includes an application layer, a PXI system, an interface control box, an adapter board, a display device and an input terminal device. The PXI system is based on NI virtual instrument technology, and is mainly used to output the excitation signal of the pitch controller and collect the response signal of the pitch controller, which includes: a PXI controller and a PXI board. The adapter board includes an interface cir...

Abstract

The invention discloses a test device for a variable pitch controller, relates to the technical field of wind power generation, and aims to provide a device capable of realizing automatic test to the variable pitch controller. The technical point of the invention is that the device comprises an application layer, a PXI (PCI eXtensions for Instrumentation) system, an interface control box, an adapter plate, display equipment and input terminal equipment, wherein the PXI system comprises a PXI controller and a PXI card; the adapter plate comprises an interface circuit and an adapter plate controller; the PXI controller and the PXI card are in signal connection through a PXI bus; the interface control box is used for connecting signal interfaces of the PXI card correspondingly to signal interfaces of the adapter plate; partial signal interfaces of the adapter plate are used for connecting signal interfaces of the interface control box to corresponding signal interfaces of a tested variable pitch controller in a distribution way; and the other signal interfaces of the adapter plate are used for connecting signal interfaces of the adapter plate controller with corresponding signal interfaces of the tested variable pitch controller.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a device for realizing automatic testing of a pitch controller before leaving the factory. Background technique [0002] The pitch controller is the core control unit of the pitch system of megawatt-scale large-scale wind turbines. In the prior art, the factory debugging of the pitch controller is that the staff use various conventional testing instruments to debug each function of the pitch controller one by one. Since it is done manually, this debugging scheme has too many human interference factors, which is difficult for The professional level of the commissioning personnel is relatively high, and it is impossible to realize the automatic and batch commissioning of the pitch controller. When the production task is heavy, it will seriously restrict the factory quantity of the controller, thereby affecting the production of the pitch system, which is the bottlene...
