A structure layout parameter determination method of an agile satellite comprises two parts of solar panel layout parameter optimization and star sensor layout parameter optimization. An optimization goal of the solar panel layout parameter optimization is set as an energy generation value of each track of a solar panel, bounded variables of the optimization goal are track parameters, attitude parameters and solar panel effective charging conditions, and variable parameters are solar panel installation angles. Optimal values of the solar panel installation angles are determined by mathematical solution. An optimization goal of the star sensor layout parameter optimization is set as a star sensor available time period, bounded variables of the optimization goal are track parameters and attitude parameters, and variable parameters are star sensor installation angles. The star sensor installation angles are iteratively computed by mathematical solution, and an available time period optimal value of each track of a star sensor can be obtained. The structure layout parameter determination method can maximumly improve application effectiveness of the agile satellite under the premise of satisfaction of a working mode of the agile satellite and a satellite mission application mode.

The invention discloses an intelligent community security and protection system, which comprises a video monitoring system, a perimeter alarm system, an identity authentication system, a building access control system, an electronic patrol system, an environment detection system and an alarm anti-theft system. The video monitoring system comprises a first camera A, a second camera A,.., an N camera A, a first C, a second positioned C,.., an N positioner C. According to the invention, the system is composed of the video monitoring system, the perimeter alarm system, the identity authentication system, the building access control system, the electronic patrol system and the alarm anti-theft system. Therefore, the all-weather and no-dead-corner monitoring inside and outside a community can be realized. Meanwhile, people and vehicles, entering and exiting the community, are checked independently. The smoke concentration and the gas concentration in the community are monitored. As aresult, the intelligent and efficient capacity of the system is effectively improved, and the benefits of residents are guaranteed to the largest extent.

The invention discloses a glass fiber felt continuous production line. The production line comprises a glass fiber yarn cluster cutting device, a settling chamber, a water spraying device, a powder scattering device, a drying device, a compaction and cutting device, a winding device and a packing device arranged in sequence. Glass fiber yarn clusters are treated by the cutting device, the settlingchamber, the water spraying device, the powder scattering device, the drying device, the compaction and cutting device, a detecting device and the winding device to form glass fiber felt rolls; and the glass fiber felt rolls are packed in cartons by the packing mechanism. Through the winding device, the electric control of an air expansion shaft is controlled to change among at least three stations, so that the labor investment is reduced, and the working efficiency is improved. Through the design of an auxiliary winding mechanism, the effective winding of the glass fiber felts on the air expansion shaft in a machining station is guaranteed, and the uneven winding is prevented. Through the design of a winding shaft placing platform, the operation efficiency of the production line is improved, and the labor cost is reduced.
