The invention provides an in-advance cable hooking system for airplane landing on a vessel. A tail hook of an airplane is drooped to a lower position to vertically and sweepingly find and hook a horizontal aerial section formed in the way that an arresting cable is pulled by a special support pulley to several meters extending out of a deck, so that the trouble caused by the fact that the airplane landing on the vessel cannot hook the arresting cable is reduced; the horizontal aerial section is easy to be normally arranged at the position slightly lower than the deck, and cannot touch the undercarriage absolutely, and the arresting cable state is not needed to be changed in a hurry at the moment that the undercarriage is passed by and the tail hook doesn't reach the arresting cable, so that the requirements for operators and equipment are greatly reduced, and the added expense of the invention can be compensated; the occasion of whether the airplane is hooked properly and can be shut down or not can be judged in advance easily, so that the occupied area of the deck is reduced, and the safe occasion can be greatly increased; a dragging cable with longer series connection is suitable for being inserted between the airplane and the tail hook correspondingly, so that the tail hook can be vertically drooped when the airplane flies at a greater safety height to further advance the time of hooking the arresting cable, the reliability is further improved, bigger airplanes can be landed on the vessel or smaller vessels can allow the airplane to land, and a great quantity of pilots can master the skill of landing on vessels more easily.

The invention provides a power calibration control method and device, wherein the method includes the following steps: adjusting a digital domain gain to realize power balance among digital domain baseband carriers and enable the power of the baseband combined wave to achieve a designated value; calculating the variation, by which the analog domain gain needs to be adjusted, when the total power of an antenna port achieves a preset value; controlling the digital domain gain to be wholly lowered by the variation; controlling the analog domain gain to be increased by the variation; and gradually increasing the digital domain gain until the total power of the antenna port achieves the preset value. Since the digital domain is not in a Digital Predistortion (DPD) loop, the adjustment of the digital domain gain would neither influence the DPD loop gain, nor have any negative effects on the operation of the DPD; and thus, by using the power calibration control method and device, it can be realized that there is no interference in a system during the whole period from starting to shutting down.

The invention provides an electric frequency heating adhesive dispensing type sewing device which comprises a glue tank and a sewing needle tube, wherein the glue tank is fixedly assembled at the lower part of a sewing machine head moving up and down, the sewing needle tube is vertically arranged, feed dogs used in pairs are assembled at the lower part of the sewing needle tube, the lower part of the feed dog is fixed on a sewing table surface, to-be-sewed fabric is placed between the upper feed dog and the lower feed dog, a vertical cavity is formed in the middle of the sewing needle tube, a slant needle point is processed at the lower part of the sewing needle tube, the sewing needle tube is communicated with the sewing needle tube through a one-way module, and the glue tank is provided with glue. When the device works, compared with a traditional sewing mode, no silk thread is needed, and a formed connecting point is single and independent, so that the bad consequence that a traditional sewing opening is split is avoided. Meanwhile, the error of the use amount of the glue for the glue connecting point is relatively small, and the adhesion quality is relatively high.
