Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The working principle of the scheme is briefly described as follows:

when a common computer is started, the fan is started together, the temperature is not increased at the moment, on one hand, resources are wasted when the fan is started, on the other hand, noise pollution is caused, on the other hand, the temperature acquisition module detects the temperature in the host and sends the temperature to the first wireless communication module connected with the main control module through the fourth wireless communication module, after the main control module receives the real-time temperature information of the host, the main control module extracts standard temperature information from the storage module for analysis and processing, when the real-time temperature is lower than the standard temperature, the main control module controls the fan driver to turn off the fan, namely, the fan driver processes from a noise source, when the real-time temperature reaches the standard temperature, the main control module starts the fan driver, on the moment, noise is sent out, the human body sensing module detects human bodies around the computer and sends the noise to the main control module through the third wireless communication module, when no person is around the computer, the noise does not affect human, the main control module has no action, when people are around the computer, the main control module controls the driver of the active noise reduction device to start the active noise reduction device, in the active noise reduction device, the noise in the computer is collected by a sound pick-up and sent into a phase inverter to carry out phase inversion to generate a signal which is the same as the noise in frequency and amplitude and has an opposite phase, and then a sound wave which is the same as the noise in frequency and amplitude and has an opposite phase is sent out by a loudspeaker to offset the noise of the running of the fan, so that the noise caused by the running of the fan can be effectively reduced, by the design, the influence of the noise on the human body is solved, meanwhile, the energy is saved to the maximum extent, the data detected by each detection module can be displayed on the display screen of the computer, when a user uses the computer, various data can be observed, the operation is convenient and practical, the power supply of the fan and the active noise reduction device is controlled by the key module, the automatic control of cooperation host system module accomplishes the processing of making an uproar of falling to the noise jointly, avoids single control mode to go wrong the back, the unable effectual problem that reduces the computer noise.

Further, the active noise reduction device comprises a sound pick-up, a phase inverter and a loudspeaker, wherein the sound pick-up is connected with the phase inverter, the phase inverter is connected with the loudspeaker, the sound pick-up collects the noise in the computer, the noise is sent into the phase inverter to be inverted, a signal which is identical with the noise in frequency, amplitude and antiphase is generated, and sound waves which are identical with the noise in frequency, amplitude and antiphase are sent out through the loudspeaker to offset the noise of the running of the fan.
