InactiveCN104044842AGuarantee classification effectGuaranteed recovery and treatment effectWaste collection and transferRefuse receptaclesThe InternetTerminal equipment
The invention discloses a garbage sorting platform based on a two-dimensional code recognition technology and a using method. The garbage sorting platform comprises a remote server, a system platform client side of the Internet of Things, and a terminal device. The system platform client side of the Internet of Things comprises a two-dimensional code intelligent sorting garbage can management module, a garbage bag handing-out management module, a user and community login management module, a garbage sorting integral module, a garbage sorting and recovering module and other device management modules. The terminal device comprises a two-dimensional code garbage bag handing-out machine, a two-dimensional code intelligent sorting garbage can, a garbage integral inquiry change machine and a garbage direct transporting device. By utilizing the mode that one household has one card, data corresponding of two-dimensional code IDs and the remote server is set up. By means of the garbage sorting platform and method, garbage can be sorted correctly and recovered effectively, the trouble caused by secondary sorting is reduced, the environmental sanitation department can count and process garbage sorting data conveniently, and the platform and the method have very important social significance.

Federated learning method and device based on block chain

The invention discloses a federated learning method and device based on a block chain. The method comprises the steps: determining the block chain; enabling the coordinator node to create a federatedlearning task according to the model original data sent by each participant node; receiving training data obtained by local training of the participant nodes; sending the to-be-updated parameters to other participant nodes according to the training data, so as to enable the other participant nodes to update own model parameters according to the to-be-updated parameters; and after model training iscompleted, issuing reward resources according to training data provided by each participant node in the training process, and writing rewards into the block chain. Compared with a traditional mode, the mutual trust problem of all parties is effectively solved; all parties participating in federated learning negotiate together to generate a coordinator node, so that the transparency of the processis improved; federated learning whole-process data is recorded in a block chain, so that the traceability of data operation is ensured; all parties are encouraged to actively participate through rewarding resources, and the enthusiasm of participants is improved.

Submersible electric pump

An improved electrical pump is first provided for use in a wellbore. The pump comprises a stator and a stator housing, and an armature and an armature housing. The stator housing and the armature housing define concentrically nested tubular bodies. The armature housing is configured to permit production fluids to flow therethrough. In one aspect, the stator and armature are assembled in connectible and interchangeable sections called “modules” that can be attached in series. In one aspect, the electrical operation of coils within the stator is protected from individual coil short-circuiting or failure by wiring them in parallel, rather than in series. In addition, each module may be wired in parallel. In this way, a failure of one stator module will not result in the failure of another stator module. In an embodiment of the present invention, the valves of the pump are capable of being retrieved by a wireline, without pulling the entire production string. A method for using a plurality of electrical pumps is also provided. The configuration of the electrical pumps allows multiple linear pumps to be placed in series with the production tubular member. Alternatively, a rotary pump design is provided which allows multiple rotary pumps to be placed in series with the production tubular member.
