A pitch controller test device

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 large wind turbines. In the prior art, the factory debugging of the pitch controller is that the staff uses various conventional test instruments to debug each function of the pitch controller one by one. Due to the manual completion, this debugging scheme has too many human interference factors. The professional level of the commissioning personnel is relatively high, and it is impossible to realize the automation and batch commissioning of the pitch controller. When the production tasks are heavy, it will severely restrict the number of controllers shipped, which will affect the production of the pitch system, which is the bottleneck of the mass manufacturing of the entire...

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
