The invention relates to a voice recognition method for power grid dispatching, which comprises the following steps that: a voice input interface is configured in a log system, input voice is acquired, the voice is recognized and converted into characters, the characters are recognized, an electric power semantic library of dispatching operation logs is established, and semantic understanding is automatically performed on the recorded logs by utilizing machine learning; after semantic understanding is carried out on the log, different voice commands are generated according to different scenes, a running event short message is automatically sent according to the voice sending commands, and an addressee number is pre-established in a database; post-processing is performed on the operation event by utilizing machine learning in combination with a knowledge graph in the electric power semantic library, and a scheduling command is generated and issued to the outside; and through incoming call voice collection, character conversion and semantic understanding, machine learning is combined with an electric power semantic library to automatically understand an incoming call intention, so that a dispatching command short message is automatically generated and sent by combining different templates according to different scenes. According to the invention, automatic scheduling can be realized, and the problem of insufficient scheduling personnel is solved.

The present invention discloses a resource allocation method and equipment for network address translation NAT. The method includes: according to the user's NAT IP, allocating NAT port allocation entries in a preset port allocation table; S102, according to the NAT port The allocation table item establishes the user's external network side session table, so as to complete the creation of the external network side session. The invention effectively solves the problem that the same user uses the same NAT address, and the user's port block allocation method expands the multiplexing degree of the NAT address by means of the port allocation table, thereby effectively solving the problem of insufficient NAT addresses.

This application provides a method and device for resource allocation, which solves the technical problem that the information in the PUCCH of the existing LTE communication system occupies the middle resource block of the bandwidth. When the terminal sends to the base station, based on the principle of minimum allocation, calculate the number of resource blocks that need to be reserved for the first information corresponding to the data that needs to be sent through the PUCCH to be K; allocate the first to i-th resource blocks among the M resource blocks resource blocks, and the M-j-th to M-th resource blocks for the first information; within the TTI, the number of resource blocks required to calculate the second information corresponding to the data that needs to be sent through the PUCCH is P; determine whether P greater than K; if P is greater than K, based on the principle of maximum allocation, allocate the first to i+(Q-K) / 2 resource blocks among the M resource blocks, and the j-(Q-K) / 2 resource blocks Give the second information to the Mth resource block.

The invention discloses a die structure for mounting a copper nut on an insulating base. The die structure comprises a front die core and a back die core. A mounting column is arranged on the front die core, the copper nut is arranged on the mounting column in a sleeving manner, a forming hole and a mounting cavity are formed in the back die core, an elastic column and an elastic cover are movablyarranged in the mounting cavity, one end of the elastic cover stretches into the forming hole and a through hole where the elastic column stretches into is formed in the elastic cover, and a cushioncover is further arranged between the elastic column and the elastic cover. When the front die core and the back die core are assembled, the mounting column and the copper nut stretch into the forminghole, a forming space where an injection medium flows into is formed between the copper nut and the inner wall of the forming hole, an eject force of the elastic cover is greater than frictional force generated by the injection medium to the copper nut in the forming space during injection molding, and the eject force of the elastic cover and the eject force of the elastic column are smaller thanpressure generated by the injection medium in the forming hole to the elastic cover during injection molding. The die structure is simple in structure and good in injection molding effect, the injection molding success rate of the insulating base is high, and meanwhile, the effective thread length of the copper nut is prolonged.
