The invention relates to an information security protection method and apparatus, and a computer-readable storage medium. The information security protection method comprises the steps of: allocating a train control and monitoring system to an intranet region, and performing region boundary security protection on the train control and monitoring system; performing communication network security protection on the train control and monitoring system; and performing terminal device security protection on the train control and monitoring system. The invention deeply integrates an application service of a train control and monitoring system, and defence-in-depth is performed on the train control and monitoring system from a plurality of dimensions such as region boundary security, communication network security and terminal device security, such that attacks initiated from an intranet and an extranet of the system can be effectively handled, and thus, the information security protection capability of the train control and monitoring system is improved.

Information security protection method and apparatus

The present disclosure provides a wind turbine blade with an improved trailing edge structure and a manufacturing method thereof. The wind turbine blade includes an upper shell, a lower shell, and a trailing edge, where a trailing edge bonding region enclosed by the upper shell, the lower shell and the trailing edge is filled with composite materials, and the composite materials are discontinuous in an airfoil chordwise direction. The manufacturing method includes the following steps: S1: manufacturing reinforcements with a same cross-sectional shape as the trailing edge filling region for composite materials; and S2: integrally molding the reinforcements, a fiber fabric and the upper shell, providing the lower shell, combining the upper shell and the lower shell, and performing heating for curing and molding. The discontinuous filling structure reduces usages of the adhesive and the reinforcements of the composite materials. The small web can improve a strength of the trailing edge region, and reduce a bonding width of the trailing edge. Therefore, the present disclosure realizes a light weight of the wind turbine blade.

A method for controlling a main circuit of a traction system is provided. The method includes: under a braking condition, controlling a protection module to be turned off; controlling the protection module to be turned on and monitoring a first current detected by a first current sensor in a case that a rail vehicle runs on a charged third rail; and controlling the protection module to be turned off and monitoring whether the rail vehicle runs on a charged third rail in a case that the first current is less than a first preset current.
