The control system of an aircraft including at least two communication networks and a controlled device control unit connected to one of them. The system determines control commands for the device with a DAL-A quality assurance level requirement and includes a set of at least three physical units each including at least two computers, an electrical power supply and a network interface device. The electrical power supplies, and the network interface devices, are of at least three different types, the computers are of at least two different types and include operating systems of at least two different types; the computers each have a DAL-C, DAL-D or DAL-E hardware and / or software quality assurance level and at least six of the computers are configured to independently determine control commands for the device. A DAL-A hardware and software quality assurance level selection logic unit is configured to select valid control commands used by the control unit to control the device.

The invention belongs to the technical field of electronic products, and particularly relates to a drilling device used for electronic product production and convenient to adjust. The problems that adrilling device for production is poor in design flexible movability, low in adjustable capacity and poor in fixity are solved. The drilling device comprises a fixed plate; four supporting columns arefixed to the outer wall of the bottom of the fixed plate through bolts and located at the four corners of the outer wall of the bottom of the fixed plate correspondingly; and the bottoms of the supporting columns are provided with rolling wheels, and rotary rods are fixed to the outer walls of one sides of the rolling wheels through bolts. The drilling device can be moved quit conveniently, moving of the device is more convenient, the trouble during moving is decreased, the heaviness during manual carrying is reduced, the flexible movability and convenience of the device are improved, the drilling device can be fixed to an electronic product needing to be drilled during production very well, the situation that the electronic product moves in the drilling process, and the drilling deviation occurs is prevented, and the fixity of the drilling device is improved.

The invention provides a nonwoven fabric which can improve these problems of the conventional technologies, can be produced at relatively low costs, is bulky and excellent in cushioning properties, has a good texture and is excellent in shaping ability at post-processing. Specifically, the present invention provides a bulky nonwoven fabric, comprising a fiber layer A containing a spiral crimp fiber and a fiber layer B, wherein the fiber layer B is laminated on at least one surface of the fiber layer A, the spiral crimp fiber of the fiber layer A and the fiber of the fiber layer B are partly entangled and integrated at the interface in a thickness direction of both layers, the fiber layer B exhibits a structure in which the layer is lifted up to the fiber layer B side between individual entangled parts; and having a specific volume of 30 cm3 / g or more.

The invention relates to the technical field of photovoltaic mounting frames, and discloses an adjustable photovoltaic mounting frame, which includes a front L-shaped cover plate, the left cavity of the front L-shaped cover plate is socketed with the transverse plate of the left front plate, The longitudinal board of the left front board is socketed with the front cavity of the left L-shaped sleeve, the rear cavity of the left L-shaped board is socketed with the longitudinal board of the left rear board, and the horizontal board of the left rear board is connected with the The left cavity of the rear L-shaped sleeve is socketed, the right cavity of the rear L-shaped sleeve is socketed with the horizontal board of the right rear board, and the longitudinal board of the right rear board is connected with the rear space of the right L-shaped board. Cavity socket, the front cavity of the right L-shaped sleeve is socketed with the longitudinal board of the right front board, and the horizontal board of the right front board is socketed with the right cavity of the front L-shaped board, so that they are combined into one area Regulating mechanism. The invention solves the problem that the existing photovoltaic system installation frame does not meet the variability of the photovoltaic system, and only needs to be adjusted, saves materials, and satisfies the variability of the photovoltaic system through adjustment.

The invention discloses a method and a system for stitch-bonded wool flocculus. The method comprises the steps that purchased scoured wool fiber raw material is further subjected to carbonization and impurity removal, and the treated wool fiber is ready for use; the scoured wool and other fibers are uniformly mixed according to the proportional requirement of technological design; after being combed, the scoured wool and other fibers are diagonally paved into a fiber net according the requirement of certain gram weight per square meters; the wool fiber net is conveyed to a stitch-bonding machine through a cloth conveying device, wool yarns are conveyed by a warp conveying device and arranged at the stitch-bonding machine, the wool fiber net is subjected to single-sided or double-sided stitch bonding processing according to the technological design requirement, and finally the wool fiber net is reinforced to form the stitch-bonded type wool flocculus; and the stitch-bonded type wool flocculus is wound on a winding mechanism so as to be tailored as wool cold protective clothing flocculus. According to the method and the system for the stitch-bonded wool flocculus, the wool leakage phenomenon of the wool fiber is obviously reduced, the net forming quality of wool fiber is also improved, the stitch-bonded wool flocculus is firmer and thinner than needled flocculus, the bulky feeling of wool cold protective clothing is effectively reduced, and the aesthetics and product grade of the wool cold protective clothing are greatly improved.
