The present application provides an audio processing method, including: collecting input data; if the input data satisfying the first condition satisfies the second condition, responding to the input data in a manner satisfying the first condition; if satisfying the first condition The input data that meets the condition does not meet the second condition, and the input data that meets the first condition is ignored. With this method, by judging whether the input data satisfying the first condition satisfies the second condition, it is determined whether to respond to the input data in the manner of the first condition, and two conditions are judged on the input data, and the judgment accuracy is high, preventing Wake up by mistake.

The present application discloses a wake-up system, a near field communication device and a wake-up method. The wake-up system includes: a receiving circuit, adapted to obtain an antenna sensing signal; a detection circuit, adapted to provide a wake-up signal according to the amplitude of the antenna sensing signal and the carrier frequency, wherein, in the low power consumption mode, when the amplitude of the antenna sensing signal is When it is greater than or equal to the threshold and the carrier frequency is consistent with the predetermined frequency, the wake-up signal is in an active state, so that the subsequent load circuit controlled by the wake-up signal is switched from the low power consumption mode to the working mode. The wake-up system effectively reduces the probability of the subsequent load circuit being woken up by mistake, and ensures the wake-up reliability.

The invention relates to a wireless network multichannel combination communication method. The method includes that S1, networking is performed on concentrators by a master station, and adjacent concentrators use different communication channels; S2, networking is performed on collectors by the concentrators, and adjacent collectors use different communication channels; S3, networking is performed on a terminal device by the collectors, the collectors use basic channels to send networking instructions in a broadcast mode to the terminal device, the terminal device receives the commutation channels of the collectors after networking succeeds, and the collectors and the terminal device are communicated with each other. The wireless network multichannel combination communication method has the advantages that multiple basic channels and wide basic channels are used for spacing, so that same frequency interference is avoided, mistaken awakening to the terminal device is prevented, power consumption of the terminal device is reduced and service life of the terminal device is prolonged; the adjacent collectors use the different communication channels, so that competition on the same channel during automatic data sending of the terminal device is lowered, real-time performance of network transmission is improved, system concurrent processing ability and system throughput are improved.

The present invention provides a computer readable storage medium and a speech recognition sound box by employing the same, and relates to the technical field of sound boxes. If a speech collection system of a sound box receives speech signals, the following steps are executed: the step 1: it is inducted whether there is a heat source or not in a preset range around the sound box, if there is a heat source, a step 2 is executed; the step 2: it is determined whether the heat source is a person or not, if yes, a step 3 is executed; and the step 3: the sound box is waken up. The computer readablestorage medium and the speech recognition sound box by employing the same can improve the wakeup accuracy of the speech recognition sound box.

The invention relates to an automatic awakening circuit applied to a wireless communication circuit in a cardiac pacemaker. An in-vitro program controller and an in-vivo cardiac pacemaker perform data transmission in a carrier-free base band digital signal mode through coupling of an inductance coil, and functions of an in-vivo cardiac pacemaker communication circuit except an awakening function are closed when data transmission of the program controller and the cardiac pacemaker is not performed. When the in-vivo cardiac pacemaker communication circuit is to be awakened, a working mode of the awakening function of the in-vivo cardiac pacemaker communication circuit is discontinuous work, i.e., 32-ms opening within 1s, when the in-vitro program controller needs to perform data interaction with the in-vivo cardiac pacemaker, the in-vivo cardiac pacemaker communication circuit is awakened through continuous sending of a specific awakening pulse group, once awakened successfully, the communication circuit is turned on and switched to a continuous working mode. Thus the in-vivo cardiac pacemaker communication circuit can be turned on through control of the in-vitro program controller, the working modes can be switched, and false awakening of the communication circuit by an interference signal can also be prevented.
