The invention discloses a method for certifying a third-party application program, a mobile terminal and a cloud server. The method for certifying the third-party application program via the mobile terminal comprises the following steps of: downloading an installation file or an upgrade file of the third-party application program; acquiring information of the third-party application program and sending the information to the cloud server; receiving an information matching result of the third-party application program retuned from the cloud server; and allowing to install the installation file or the upgrade file of the third-party application program when the information of the third-party application program is matched with certification information stored in the cloud server. The method can be used for avoiding the incapability of normally installing a safe application program or the installation of unsafe application program information by mistake caused by untimely upgrading of the certification information of the third-party application program, effectively improving the security of the mobile terminal and avoiding the affect on the normal use of the mobile terminal.

The invention discloses an explosion suppression and intrinsically safe type frequency conversion and speed regulation integral machine with 3300V for a mine. The frequency conversion and speed regulation integral machine comprises an electric motor and a frequency converter, wherein the frequency converter is arranged in the upper part of the electric motor, a motive force power supply cavity is arranged on the rear end of the electric motor, a control module which is electrically connected with the frequency converter is arranged on a casing of the frequency converter, a frequency-converted power and energy storage module is arranged inside the frequency converter, and the electric motor is a multi-winding electric motor. The frequency-converted power and energy storage module of the explosion suppression and intrinsically safe type frequency conversion and speed regulation integral machine with 3300V for the mine is distributed in a layered shape from bottom to top, and thus the overall size of the frequency converter is reduced. A multi-circuit independent coil group is adopted for the multi-winding electric motor, each independent coil group can be independently matched with a power supply with the same circuit number, thus the requirement of simultaneous input of multiple power supplies is met, the problem of outputting by the electric motor which is used for matching with the multiple power supplies of the frequency converter is solved, and the matching of the electric motor and multiple output of the frequency converter is realized. The multiple output is adopted for the frequency converter topology structure of the frequency converter, so that the output voltage of each circuit is relatively decreased, and the requirement of a withstand voltage of a power appliance is further lowered.

The invention relates to a BIM-based air duct system prefabricating method, which comprises the following steps of constructing a multi-specialty design three-dimensional model based on a BIM technology; optimizing pipeline system arrangement of the multi-specialty design three-dimensional model to obtain a construction three-dimensional model; splitting from a pipeline system of the constructionthree-dimensional model to obtain a standard section air pipe model and a parameter section air pipe fitting model; according to the standard section air pipe model, a corresponding standard section air pipe is obtained through production, the standard section air pipe is installed on site, then space connection data needed by the parameter section air pipe fitting are obtained through on-site measurement, and therefore geometrical parameters of the parameter section air pipe fitting model are updated, and according to the updated parameter section air pipe fitting model, the parameter sectionair pipe fitting is obtained. Corresponding parameter section air pipe fittings are obtained through production. Compared with the prior art, the parameter section air pipe fitting matched with the on-site installation distance can be accurately machined. Therefore, the problem that a prefabricated air pipe system cannot be installed due to on-site operation and other construction errors is solved.
