The invention is applicable to the technical field of glasses, and discloses a pair of audio output intelligent glasses. A sound guide cavity and a sound guide opening are used for sound spreading and are arranged on each glasses leg; each sound guide cavity communicates with the corresponding sound guide opening to form a sound spreading passage; the sound guide opening is positioned in a position near the ear of the corresponding glasses leg. The sound can be conducted to the sound guide openings near the ears through the sound guide cavities; the audio output such as music listening through the glasses and the like can be realized; inconvenience due to the use of earphones can be reduced; meanwhile, the receiving of the outside sound is not influenced during the use; the structure is compact; the carrying and the use are convenient. Meanwhile, the sound guide openings are positioned near the ears, so that the sound does not enter the ears in a linear way; the injury on auditory acuity cannot be easily caused; meanwhile, the compression on the ears cannot be caused; the comfort is enhanced.

The invention provides a three-component transient electromagnetic method receiving device comprising a base which is provided with at least three height-adjustable supporting rods. A cuboid block is fixedly connected and supported on the supporting rods. Each plane of the cuboid block is provided with multiple transverse guide rails and vertical guide rails which are arranged to be parallel to the sides of each plane of the cuboid block. The transverse guide rails and the vertical guide rails arranged on each plane are perpendicularly arranged. All the transverse guide rails and the vertical guide rails are provided with coil supporting frames. The coil supporting frames on the transverse guide rails or the vertical guide rails of the same plane are oppositely arranged. The device and the coils are arranged in a split way so that transportation and storage are facilitated; the transverse guide rails, the vertical guide rails and the cooperated coil supporting frames are arranged so as to realize the objective of adjustable coil position; and the supporting rods of controllable and adjustable height are adopted to support the cuboid block so that the position of the cuboid block can be conveniently adjusted to be level through indication of a level display instrument and the universality of the device can be enhanced.

The invention relates to an electronic mutual inductor synchronization method based on PPS. A merging unit receives a pulse per second (PPS) output by a master clock of a synchronization system in an intelligent transformer substation; the merging unit utilizes a field programmable gate array (FPGA) inside to detect a PPS signal, and filters interference pulses according to crystal count; and a digital signal processor (DSP) in the merging unit determines an interpolation moment, namely a resampling moment according to a PPS on-time moment and a sampling rate of the merging unit, and simultaneously the DSP compensates the crystal deviation dynamically through dynamic adjustment of the resampling moment. The electronic mutual inductor synchronization method not only can recognize correct PPS, but also can filter interference pulses without influencing receiving of the correct PPS, and simultaneously can track the synchronous state of a GPS clock quickly when a master clock is switched from an asynchronous state to a synchronous state; when the factors such as the environment temperature and the like are changed, the output data synchronization error is not larger than plus / minus 1 mus through dynamic adjustment of the resampling moment by the DSP, thus not only solving the problem of cumulative deviation, but also meeting the requirement of automation equipments of the intelligent transformer substation for protection, measurement and control, metering and the like.
