This invention relates to a control method and a system for speaking in PoC in a group session technology field, which introduces a manager terminal, which arranges orders of speaking and distributes the right of appointing the speaking to the PoC server to distribute the right to an assigned PoC server.

The invention provides a rocker-type transverse shearer. The shearer comprises a machine body consisting of a plurality of case separation cavities, and a power transmission chain, a rocker, a roller and a coiling block which are respectively arranged inside the case separation cavities, wherein a sliding board is arranged at the lower part of the machine body; and the power transmission chain comprises a main transmission wheel connected with a motor spindle and a pair of secondary transmission wheels which are engaged with one another for driving front and back vertical transmission shafts to output power so as to drive a last-stage transmission gear shaft, a roller on a gear shaft of a speed-reducing transmission box, a chain wheel transmission device and cutting teeth to run synchronously. Therefore, a technical scheme of transverse full-section no-dead-angle all-dimensional coal mining is realized. The rocker-type transverse shearer can overcome the defects that the conventional coal mining device can be only used for exploiting coal layers on the top face and the lateral face of a small-dip roadway structure while coal layers between two rollers cannot be synchronously exploited, solves the difficult problem that coal layers on the bottom face of the structure with a roadway dig being more than 25 degrees and coal layers between the two rollers are abandoned without exploitation, is applicable to exploitation of the coal layer on the bottom face of the roadway dig structure of a coal mine, and is particularly applicable to the full-section no-dead-angle all-dimensional exploitation of the coal layer on the bottom face of the structure with the roadway dig being more than 25 degrees and thin coal layers of mediate and small-sized coal mines.

A cleaning assembly for a harvester operable to clean a crop while moving along a direction of the crop flow and comprising multiple cleaning sub-assemblies has a control system coupled to each of the cleaning sub-assemblies and operable to control the operation of each of the cleaning sub-assemblies in function of separate cleaning sub-assembly control settings for each of the cleaning sub-assemblies.

The invention belongs to the technical field of wastewater treatment and relates to a synchronous nitrogen and carbon removal set and method for wastewater of aquatic product processing. A fixture for holding combined filler is disposed within a reactor; an aerator is provided below the combined filler; an air compressor is provided outside the reactor; the air compressor is communicated with the aerator through a gas incoming pipe; the same side of the reactor is provided with three valves; a sludge pipe is disposed at the bottom of the reactor; marine heterotrophic nitrifying bacterium added to the reactor grows rich on the combined filler and forms a film before the wastewater of aquatic product process is guided into the reactor, the air compressor introduces oxygen into the reactor, the marine heterotrophic nitrifying bacterium converts ammonia nitrogen into nitrate nitrogen using part of organics as electron donors and converts the nitrate nitrogen into nitrogen to be discharged, using the rest of the organics as carbon sources. The whole process is simple, operating and controlling is flexible, the wastewater can be synchronously subjected to nitrogen and carbon removal, energy consumption is lower, the production cost is low, the economic benefit is good, and the synchronous nitrogen and carbon removal set and method is convenient to popularize and apply.
