The invention provides an air draft and dust removal device and an equipment management method thereof. The air draft and dust removal device comprises a confluence structure, a plurality of air pipes and a plurality of air draft piece assemblies. Wherein the multiple air pipes are parallel to one another; the confluence structure is provided with a plurality of confluence inlets and a confluence outlet; one end of the air pipe is connected with one confluence inlet, and the other end of the air pipe is sealed; the flow direction of air flow in the air pipes is perpendicular to the flow direction of air flow in the confluence structure. The air draft part assembly is fixed to the side face of the air pipe, and the air draft part assembly is used for outputting air flow into the air pipe and preventing the air flow in the air pipe from flowing out of the air draft part assembly to the outside. According to the invention, violent interference generated during airflow confluence can be eliminated, the loss of airflow speed is reduced, and rapid discharge of smoke dust and the like is accelerated, so that the stable dust removal effect of a working area and the effective utilization rate of the fan are ensured.

The application relates to the technical field of drilling devices, and discloses a drilling device for metal computer support machining and an operation method thereof, which comprises a driven feeding mechanism and a buffer liquid flow control mechanism. The drilling device for metal computer support machining and the operation method thereof utilize the liquid output by a hydraulic system to control the feeding of a drill bit, realize systematic feeding pressure control on the basis of guaranteeing the driven feeding, can guarantee the drilling efficiency of the drill bit on the metal computer support and the effective utilization rate of kinetic energy on one hand, and can effectively prevent the drill bit and the metal computer support from being deformed due to the overloading of the feeding pressure on the other hand, so that the limitation of the equipment in the use process is reduced, and the self-adaptability of the equipment is improved.

The invention discloses a voice recognition model training method and device, a medium, equipment and a program product, and relates to the technical field of artificial intelligence, and the method comprises the steps: determining the voice feature length of each piece of sample voice data of a sample data set and the text label length of each text label; performing sample batching on the plurality of samples based on the sequence of the voice feature length and the text label length to obtain a plurality of batch data, the sample size of each batch of data being limited by a preset batch size and a preset video memory index, and the preset batch size being used for limiting the sample size upper limit of the batch data; the preset video memory index is an expected value required to be reached by a batch video memory index of the batch data, and the batch video memory index is used for indicating the video memory consumption degree of the batch data in the model training process and is determined by performing video memory consumption estimation on the batch data based on the voice feature length and the text label length; and training the initial recognition model based on the plurality of batch data to obtain a target speech recognition model. The training efficiency and the resource utilization rate can be remarkably improved.

This invention provides a method for processing database query statements and related products, relating to the field of database optimization. The method includes: obtaining the query statement to be processed; searching for the execution state corresponding to the query statement from a pre-established execution state cache record; if found, the database executor directly loads the execution state to process the query statement; if not found, obtaining the execution plan of the query statement, executing the execution plan by the executor, and saving the execution state of the executor to the execution state cache record. The solution of this invention allows the database executor to directly load the execution state to process the query statement, directly reusing the already initialized execution state, avoiding the time-consuming process of repeated initialization by the executor; it shortens the overall processing flow of the query statement, and is particularly suitable for scenarios where the same query is executed repeatedly.

The application discloses a papermaking method reconstituted tobacco pulping stability control system and a control method thereof, wherein the papermaking method reconstituted tobacco pulping stability control system comprises a pre-beating pulp tank, a first low-concentration double-disc refiner, a second low-concentration double-disc refiner, a cylindrical refiner and a post-beating pulp tank, a reflux pipeline is arranged between the second low-concentration double-disc refiner outlet and the pre-beating pulp tank, a first regulating component is arranged between the pre-beating pulp tank and the first low-concentration double-disc refiner, a second regulating component is arranged between the second low-concentration double-disc refiner and the cylindrical refiner, and a third regulating component is arranged on the reflux pipeline; the first regulating component, the second regulating component and the third regulating component in the application can realize real-time regulation of the flow at each part in the whole system; the design of the reflux pipeline and the third regulating component realizes the staged control of the pulp throughput of the low-concentration double-disc refiner and the cylindrical refiner, thereby ensuring the continuous operation and stability of the pulping process and improving the pulp quality stability.
