Description
Technical field
The present invention relates to a kind of display device and display methods, especially a kind of wind electricity change paddle Drive Status display device
And display methods.
Background technology
Wind electricity change paddle control application is more and more extensive, and as the core component of pitch control, driver for variable pitch undertakes more
Come more functions, state control planning to system cost, safe design, state representation, user experience etc..
Four major class, each state such as the state of driver for variable pitch includes standby, operation, failure, is powered on can separate again
Different sub- states, wherein operating status can be divided into rotating forward, two groups of reversion according to the applicable cases of driver, rotate forward, reversion
Unloaded, band load, fully loaded and overload etc. need to be characterized according to the difference of load condition；Malfunction can according to the applicable cases of driver
It is divided into several type faults.
Clearly accurately to control and characterizing these states, method some used at present passes through multiple multistage Digital sums
Pipe, LCD display etc. can also characterize complicated state, need to be equipped with special control resources of chip although these methods are intuitive
With more complex control circuit, cost is increased, implements and also increases difficulty；Also have by a small number of light emitting diodes come
It realizes, these methods can only simply characterize state, cannot intuitively show, it is not convenient enough to use in actual application.
Further, in existing display methods, when some display device breaks down, driving can not be just shown
The current corresponding state of device, at this time if driver is in overload or malfunction, and staff timely can not obtain
Know, this may cause serious damage to driver and other variable pitch equipment, generate irremediable loss, exist greatly
Security risk.
