The present application relates to the technical field of gas engine intake, and particularly relates to a gas engine set intake intelligent filtering diagnosis and blockage early warning device, which comprises a gas intake cylinder, a middle frame is fixedly connected through a middle part of an outer wall of the gas intake cylinder, a round block is sealingly and rotatably connected between upper and lower sides of the middle frame on an inner side of the gas intake cylinder, and four air passing holes are formed through a top end of the round block, the original single gas screening channel is divided into four parts through the arrangement of the middle frame, the round block, a replacement mechanism and a limiting mechanism, and the replacement mechanism is arranged, so that when the screen is replaced, one of the air passing holes is individually closed to replace the screen, the normal gas intake of the gas engine set is not affected, the equipment does not need to be stopped for maintenance, workers do not need to disassemble, and whether the screen is blocked can be judged according to gas flow data of two ends of the screen measured by a pressure tapping pipe, so that the screen can be replaced.

The application relates to the technical field of Android development, and discloses a cross-row-column irregular list moving and sorting method and device based on RecyclerView, aiming to solve the problem that the existing method cannot maintain the integrity and stability of a grid layout, and the scheme mainly comprises the following steps: defining a list item data object for storing self position information, self span information and adjacent span information of adjacent list items; sequentially traversing data in an original data list, converting the data into list item data objects, and generating a regularly arranged list item data object set; when a moving and sorting instruction is received, calculating a data exchange scheme, reordering the list item data object set, and synchronously updating information of affected list item data objects; comparing the list item data object set before and after moving and sorting, calculating a data difference set, and driving a RecyclerView adapter to perform local UI refreshing. The application maintains the integrity and stability of the grid layout and is suitable for cross-row-column irregular lists.
