The invention discloses a distribution transformer operation sound signal acquisition method based on crowd sensing, which comprises the following steps: formulating an excitation mechanism, and issuing a sensing task to a user based on the excitation mechanism; collecting, by the user, data based on the received sensing task, and determining, by the terminal, the authenticity of the data according to the collected data; and if the data is real, transmitting the data to a database for storage, and completing acquisition of the operation sound signals of the distribution transformer. According to the invention, capital investment and human and material resource consumption can be effectively saved. The method can quickly, conveniently, economically and comprehensively perceive the sound signal information, and can ensure that the information is kept complete, the signal is not distorted and the modes are not aliasing while reducing the data volume. In addition, the method is good in flexibility, high in compat
