Pre-selection method of low-ore grade magnetic iron ore

InactiveCN101502819ASolve the costSolve the problem of large tailingsSievingScreeningSeparation technologyMagnetite
The invention discloses a preselecting method of low-grade magnetic iron ore, comprising the steps of crushing the raw ore of the magnetic iron ore by coarse crushing, intermediate crushing and fine crushing operations, conveying to subject to ultra-fine crushing operation, and then crushing by a high-pressure roller mill, scattering the crushed product by a wet cylindrical sieve, conveying the ore on the cylindrical sieve to the vibrating sieve by a belt to perform wet gradation, conveying the ore on the vibrating sieve to a dry magnetic separator by the belt to discard the waste, returning the ore concentrate of the dry magnetic separator to the high-pressure roller mill to crush the ore concentrate again, perform magnetic separation and discarding tailings of the ore concentrate below the vibrating sieve and the ore concentrate below the cylindrical sieve in a wet coarse grain intermediate-field intensity magnetic separator, and selecting the coarse ore concentrate of the intermediate-field intensity magnetic separator by a grinding separation technology. The invention has the advantages that the invention selects quantities of qualified mine tailings by wet magnetic separation before grinding ore, reduces ore grinding work, reduces ore grinding energy consumption and has high system processing capacity; the invention can be widely used in magnetic ore dressing plant, and in particular suitable for treatment of preselecting low-grade magnetic iron ore with the iron grade lower than or equal to 22%.

Method and apparatus for downlink multi-channel packet combined scheduling in mobile communication system

The present invention sets forth a method for performing packet combined scheduling of dedicated transport channels for packet services in UMTS downlinks, comprising the following steps: a) prior to each DCH scheduling period, performing pre-selection processing of a transport format combination of each DPCH according to the predetermined restriction conditions for the DCH combined packet scheduling, so as to determine a usable transport format combination set for each DPCH; b) restricting a total downlink transmit power of DCHs for NRT packet services to a schedulable power not exceeding a schedulable power value in the estimation of a total downlink power during said scheduling period; c) based on the fairness of DCH transportation and the QoS requirements of the DCH-borne services, determining weighted values which the respective DCHs correspond to in the optimization of the DCH combined packet scheduling; and d) based on the results of steps a), b), and c), calculating the maximum number of bits which each DCH is schedulable to output, using a 0-1 programming algorithm. The present invention guarantees the fairness, priority and QoS (Quality of Service) of different DCHs and can achieve maximum total data throughput.

Non-intrusive household appliance load identification method

The invention belongs to the technical field of power load identification, and particularly relates to a non-intrusive household appliance load identification method. Firstly, a household appliance load is regarded as an independent system, steady-state voltage and steady-state current data in the case of independent operation of each household appliance load are acquired, and according to steady-state current wave crest coefficients, loads are divided into a type of approximately linear loads and a type of nonlinear loads; the steady-state voltage then serves as input data, the steady-state current serves as output data, a system identification method is used for building models for the two types of loads, and a model library is formed; and finally, the steady-state voltage and the steady-state current of a to-be-identified load are acquired, a model library type is determined through pre-selection, and the load is identified according to a model matching principle. The actually-measured data can be used for effectively identifying the linear loads and the nonlinear loads, the algorithm is simple, the operational efficiency is quick, the method can be applied to a condition with increased loads in a home network, large-scale training is not needed when a new load is added to a power consumption network, and a model only needs to be built for the load, and the model is added to the corresponding model library.

Container scheduling method associated with time based on Kubernetes container cluster

The invention discloses a container scheduling method associated with time based on a Kubernetes container cluster, and belongs to the technical field of cloud computing. According to the method, whether judgment is carried out in a time range or not is added between a pre-selection strategy and an optimal selection strategy of a scheduler of the Kubernetes cluster; calculating the average load score of the pre-selected available Node. According to the technical scheme provided by the invention, whether the scheduling operation is further carried out or not can be decided by comparing the scheduling operation with the preset score, so that the normal operation of the existing business application is ensured, and some tasks with time correlation can better utilize resources in the cluster.For example, in the morning at night, According to the technical scheme of the invention, when the load of the business application is large, the time period is the time period with the load of most business applications being not heavy, the time period is very suitable for some big data offline computing tasks, the tasks are allocated to the Node where the business application is located within the time period, the operation efficiency of the big data tasks can be improved, and the utilization rate of hardware resources in the cluster can be improved.
