The present invention can realize the signal port test of pitch control device to be measured, simulated failure is surveyedExamination, charging flow test, temperature acquisition test and encoder control test.Introduce the present invention separately below and test each method of testing of device:
Such as Fig. 3, the test device of the present invention can realize encoder and control test, and its flow process comprises the following steps:
Step E01: application layer sends encoder to PXI controller and controls test instruction.
Step E02:PXI controller controls PXI board and exports releasing of brake order to pitch control device to be measured.
Step E03: application layer detects whether pitch control device to be measured exports releasing of brake signal, such as Fig. 3, in the present embodiment, when digital signal output end DA1.1～3.1 of pitch control device to be measured are high for output releasing of brake signal: terminate if it is not, application layer reports an error and tests.
Step E04:PXI controller controls PXI board and exports servo enable supply signal to pitch control device to be measured；In the present embodiment, PXI board exports high level to digital quantity input port DE2.1～4.1 of pitch control device to be measured is that PXI board outputs servo enable supply signal.
Under normal circumstances, pitch control device to be measured should enable signal receiving output servo after servo enables supply signal, therefore following step E05 is: application layer detects whether pitch control device to be measured exports servo enable signal: terminate if it is not, application layer reports an error and tests.In the present embodiment, when digital signal output end mouth DA1.2～3.2 of pitch control device to be measured export and are high, illustrate that pitch control device to be measured successfully outputs servo and enables signal.
Step E06:PXI controller controls PXI board to pitch control device output motor speed to be measured, expection angle, current of electric analogue signal and motor temperature analogue signal；Wherein current of electric analogue signal, temperature analog signal be PXI controller according to motor speed, the amount that output is linear with motor speed.In real process, the rotating speed of motor is not at the uniform velocity, when test, for simplicity, it is possible to make PXI controller be set at the uniform velocity by motor speed, without rate curve when going simulated machine real-world operation.
Under normal circumstances, pitch control device to be measured receive after motor speed, expection angle, current of electric analogue signal and motor temperature analogue signal can the analog voltage signal of output coder clock signal and reaction predetermined angle, therefore step E07 is: adaptation board controller receives the encoder clock signal of pitch control device to be measured output and the analog voltage signal of reaction predetermined angle.
Step E08: the adaptation board controller analog voltage signal according to the persistent period and reaction predetermined angle that receive encoder clock, real-time generation motor angle analogue signal also exports to pitch control device to be measured.Total persistent period of encoder clock (i.e. encoder clock signal send moment play the interval of encoded clock signal finish time) is relevant to predetermined angle, predetermined angle is more big, then to send encoder clock more long for signal duration for tested pitch control device.Described motor angle is relevant to the persistent period of encoder clock (namely adaptation board controller plays current interval from the moment receiving encoder clock signal), the persistent period of encoder clock is more long, the motor angle that adaptation board controller generates is more big, until encoded clock signal terminates, the motor angle that adaptation board controller generates reaches predetermined angle.
In actual normal power generation situation, pitch control device can to main control unit output motor actual angle after receiving motor real-time angular, therefore in step E09: application layer detects pitch control device to be measured whether output motor angle, motor current signal and motor temperature signal in real time: terminate if it is not, application layer reports an error and tests；If so, then gathering motor angle, motor current signal and motor temperature signal, application layer also detects whether the motor angle of pitch control device to be measured output reaches expection angle simultaneously, if reaching expection angle, application layer record test result and test terminate.

In described temperature acquisition test process, the effect of adaptation board is the test resistance provided for pitch control device to be measured, namely provides the input of resistance value signal, and its flow process includes:
Step T01: application layer sends temperature acquisition test instruction to adaptation board controller.
Step T02: the switching tube that adaptation board controller controls in critesistor analog circuit sequentially turns on, and corresponding relay contact sequentially closes.
The result that step T02 performs is that first test resistance of critesistor analog circuit, second test resistance and the 3rd test resistance are sequentially ingressed into the corresponding port of pitch control device to be measured, pitch control device to be measured detects the resistance of three test resistance successively, according to PT100 phasing meter, resistance is converted to successively temperature information, therefore in following step T03: whether application layer exports correct temperature value when detecting controller to be measured first test resistance of detection, if so, application layer collection record this temperature signal.If it is not, then illustrate that pitch control device to be measured cannot complete thermometric, application layer reports an error and tests and terminates.
Whether application layer exports correct temperature value when continuing to detect controller to be measured second test resistance of detection, if so, application layer collection record this temperature signal.If it is not, then application layer reports an error and tests and terminates.
Application layer continues to detect whether controller to be measured exports correct temperature value when detecting the 3rd test resistance, if so, application layer collection record this temperature signal.Test terminates.If it is not, then application layer reports an error and tests and terminates.
