And a warm-keeping effect can be achieved on the shanks of the user in winter.

The utility model belongs to the technical field of building wallboards, and discloses an aerogel fireproof heat-insulation composite wallboard which comprises a mortar layer and a first heat-insulation layer bonded with the mortar layer, a light steel keel is arranged on the layer face, away from the mortar layer, of the first heat-insulation layer, an aerogel heat-insulation layer is arranged on the other side of the light steel keel, and the aerogel heat-insulation layer is arranged on the first heat-insulation layer. An aerogel flame-retardant layer is arranged on the other side of the aerogel heat insulation layer, and a decorative wall plate is arranged on the other side of the aerogel flame-retardant layer; one section of each sewing connecting steel wire is fixed on the mortar layer, the other end of each sewing connecting steel wire is fixed on the decorative wallboard, and the sewing connecting steel wires are fixed in a crossed manner. According to the fireproof wallboard, indoor heat can be prevented from being dissipated in winter, external heat can also be prevented from entering a room in summer, the fireproof function of the wallboard is further improved due to the design of the aerogel flame-retardant layer, and the wallboard is firmer and not prone to cracking due to the fact that the connecting steel wires are sewn.

The purpose of the present application is to provide a method and device for verifying the switching of summer and winter time, which realizes the embedding of the traditional verification logic depending on external test tools and manual intervention into the firmware runtime system of the device, and constructs a closed-loop summer time DST self-verification mechanism with the capabilities of rule analysis, event pre-play, execution monitoring, result comparison and abnormal response. The mechanism does not depend on network connection or external debugging interface, and can still complete the integrity check of the DST switching behavior independently when the device is in a completely offline state, thereby solving the problems of time confusion, data distortion and service interruption caused by the lack of self-checking capability in the prior art.
