A method for operating a snapping device to harvest stalk crop relies upon stripper plates disposed in pairs and having a variable spacing therebetween. A snapping gap is formed by or in the variable spacing. Plant stalks are drawn into the snapping gap to sever crop fruit from crop stalks by the stripper plates. The diameter of the crop stalks is determined before entry into the snapping gap by a sensor device disposed in front of the snapping gap. A width of the snapping gap is adjusted depending on the diameter value that is determined.

A system based on the continuous measurement (20) of the diameter of a cylindrical object (1) moving, laid down, on a belt conveyor (10) allows dimensional compliance of the latter object to be checked.

The measurement system (20) may be coupled with a sorting system based on ejection out of the conveyor (10) by projecting a gas through a transverse nozzle (42).

By means of the system according to the invention, it is possible to continuously determine whether a nuclear fuel pellet (1), in particular after rectification (2), has to be rejected or not.

The invention discloses an insulator quality monitoring device of an electric power system. The device comprises an insulator hanging mechanism, electric field sensors, a wireless transmitting module, device moving modules, a wire and a control center monitoring module. The insulator quality monitoring device of the electric power system can wirelessly monitor the quality conditions of fixed insulators, monitored information is transmitted to the control center monitoring module by using the wireless transmitting module, the insulators are regarded as losing efficacy if the deviation between the monitored information and record data in a system is larger than 2%, and needs for manual overhaul are prompted. Further, the insulators in the whole circuit range can be patrolled automatically according to needs, and a traditional insulator monitoring device cannot achieve the operation.

The embodiment of the invention provides a method and device for monitoring the quality of an information transmission channel, a storage medium and equipment. The method comprises the steps of detecting whether at least one piece of information sent to a user terminal through an information transmission channel is used by a user of the user terminal or not; obtaining the proportion of the information used by the user in the at least one piece of information; and according to the proportion, generating a monitoring result representing the quality of the information transmission channel, the proportion being in direct proportion to the quality of the information transmission channel. Through the method, the quality of each information transmission channel can be conveniently and quickly detected.
