This invention discloses a carbon fiber double-double layup method for a composite material fuselage stringer structure. The stringer is fixed to the inside of the aircraft fuselage cylinder and adopts a carbon fiber double-double layup structure. First, the two angle parameters φ and ψ of the double-double layup are set within the range of 0º-180º and different combinations are made. Then, under a preset bending moment and a preset number of layers, the optimal combination of angle parameters (±φ, ±ψ) is determined by strength calculation. Finally, the double-double layup is repeated in a fixed cycle along the stacking direction according to the determined combination of angle parameters (±φ, ±ψ). This invention can improve the design stiffness and strength of the stringer with the same material usage, or reduce the amount of composite material used with the same stiffness or strength, resulting in high carbon fiber strength utilization and high material utilization rate.

The invention discloses a Beidou short message-based power distribution terminal communication optimization method and system, and the method is applied to a Beidou short message-based power distribution automation system, a Beidou communication module obtains a response message of a power distribution automation terminal, sets the highest priority for a remote control message, reports the remote control message in real time, shields a frequent displacement message for a remote signaling message, and carries out the real-time monitoring of the remote signaling message. Key information is extracted from the remaining remote signaling messages, protocol conversion is carried out according to a private protocol, then the messages are reported, and the telemetering messages are reported through total calling and important remote signaling deflection triggering; the data is compressed and numbered before being reported, so that channel blockage and message loss are avoided; and the Beidou short message communication manager obtains a remote control instruction of the power distribution automation master station, directly responds to a corresponding message to the power distribution automation master station if the remote control instruction is a remote control selection instruction or a remote control revocation instruction, directly issues the corresponding message if the remote control instruction is a remote control execution instruction, and starts a retransmission mechanism if the remote control execution confirmation message is overtime. According to the invention, the integrity and reliability of data transmission are systematically improved.

This invention provides a reinforcement and transmission device for the attachment support arm of a tower crane in a double-sided coal bunker boiler unit. The device includes a first tie rod, a second tie rod, a third tie rod, a first transmission beam, and a second transmission beam at the first level, and a first temporary reinforcement transmission beam, a second temporary reinforcement transmission beam, a third temporary reinforcement transmission beam, and a fourth temporary reinforcement transmission beam at the second level. This invention effectively transmits the load of the tower crane exceeding its independent height to the attachment points of the boiler steel structure through the device, ensuring that the attachment points of the boiler steel structure do not experience irreversible deformation or tearing damage. Simultaneously, it ensures that the overall column grid of the boiler does not experience irreversible displacement before an effective overall column grid is formed.
