    Abstract: The present disclosure relates to a system and method for matching performance with score. The method may include acquiring performance information in a preset time period, wherein the performance information is related to a musical device. The method may also include analyzing the performance information and obtaining a played music score in the preset time period, wherein the played music score contains the performance information. The method may further include comparing the played music score with one or more standard music scores. The method may still further include identifying a standard music score from the one or more standard music score based on the comparison of the played music score with the one or more standard music scores, wherein a matching degree between the played music score and the identified standard music score reaches a preset value.

    Abstract: A heat dissipation system for a smart piano may include a heat dissipation driver, a heat dissipation device, a sensor, a protection circuit and a hardware processor. The sensor may be configured to detect a thermal parameter of an execution device of the smart piano. The protection circuit may be configured to analyze the thermal parameter to generate a protection signal. The hardware processor may be configured to determine a preset algorithm, generate a control signal according to the protection signal and the preset algorithm, and control a heat dissipation condition of the smart piano. The controlling the heat dissipation condition of the smart piano may include control an operation condition of the execution device and/or the heat dissipation device. The controlling may include controlling an output power of the execution device and/or the heat dissipation device.
