Meanwhile, the receiving module 130 may perform digital-to-analog conversion and preprocessing on the bluetooth signal converted by the bluetooth receiver, so as to completely transmit the relevant signal to the wind turbine main control system.
For example, a bluetooth receiver and a microcontroller may be disposed in the receiving module 130, and specific parameters and components may be set according to actual situations, which is not limited in the embodiments of the present disclosure.

When the weak current signal quantity of the variable pitch slip ring in the second variable pitch system signal is smaller than the weak current signal of the variable pitch slip ring in the converted bluetooth signal, or the weak current signal of the variable pitch slip ring is not detected, the receiving module 130 may timely transmit the weak current signal of the variable pitch slip ring in the converted bluetooth signal to the main control system of the wind turbine. The receiving module 130 may further perform digital-to-analog conversion and preprocessing on the bluetooth signal converted by the bluetooth receiver, so as to completely transmit the relevant signal to the wind turbine main control system.

The display module 160 is configured to display alarm information, and may be an LED (light-emitting diode) display screen. It should be understood that the LED display screen displays various information by controlling the semiconductor light emitting diode. In the embodiment of the disclosure, the alarm information sent by the receiving module 130 may be displayed using an LED display screen.
For example, the content, pixel pitch, brightness, color, etc. of the LED display screen may be set according to actual situations, which is not limited by the embodiments of the present disclosure. For example, "pitch system signal lost" with a red font on the display, and so on.
Through the above technical scheme, when the receiving module 130 in the data acquisition system does not receive the first pitch system signal, the alarm information of the first pitch system signal loss can be sent to the display module 160, and the alarm information is displayed by the LED display screen, so as to achieve the effect of timely alarm.
