Abstract
The invention discloses a status display device and display method of a wind power variable-pitch driver. The driver is included and comprises a detecting device and a displaying device. The detecting device is electrically connected with the displaying device and is used for detecting the working status of the driver and the working status of the displaying device and controlling the work of the displaying device. The displaying device is used for displaying the working status of the driver and comprises a first status displaying unit and a second status displaying unit. The first status displaying unit and the second status displaying unit display the major status, the sub-status and other supplementary statuses jointly or separately. According to the status display device and display method of the wind power variable-pitch driver, the number of the displaying units is decreased, resources occupied by a control chip are reduced, the complexity of a control circuit is further decreased, the hardware cost is lowered, and the difficulty of software control is lowered. All the control statuses can be represented directly and wholly. Multiple assurances are achieved when part of the displaying units break down, and risks and hidden dangers caused by displaying faults are avoided.
Description
Technical field
The present invention relates to a kind of display unit and display method, especially a kind of wind electricity change paddle Drive Status display unit and display method.
Background technique
It is more and more extensive that wind electricity change paddle controls application, and as the core component becoming oar control, driver for variable pitch bears increasing function, and its state control planning is to system cost, safe design, state representation, Consumer's Experience etc.
The four large classes such as the state of driver for variable pitch comprises standby, operation, fault, power on, each state can separate again different sub-states, wherein running state can be divided into rotating forward according to the applicable cases of driver, two groups of reversing, rotate forward, reverse need characterize zero load according to the difference of load condition, band carries, fully loaded and overload etc.; Fault state can be divided into some type fault according to the applicable cases of driver.
Control accurately for clear and characterize these states, the method of current use have by multiple multi-segment nixie tube, LCD display etc., although these methods are directly perceived, also complicated state can be characterized, but special control chip resource and more complicated control circuit need be equipped with, add cost, implement and too increase difficulty; Also have and realized by the light emitting diode of minority, these methods simply can only characterize state, can not intuitively show, and it is convenient not to use in actual application.
Further, in existing display method, when certain display unit breaks down, it just cannot demonstrate the current corresponding state of driver, if now driver is in overload or fault state, and staff cannot learn in time, this just may become oarage to driver and other and cause serious infringement, produce irremediable loss, there is great potential safety hazard.
Summary of the invention
Object of the present invention is exactly to solve the above-mentioned problems in the prior art, provides a kind of display unit by the combination of two groups of display units or display wind electricity change paddle driver operation separately, fault, standby or major state and the sub-state thereof such as to power on and display method; Concrete, by arranging plurality of display modes, even if when a certain display unit breaks down, display unit and the display method of described driver current operating state still can be shown accurately and effectively.
