System and method for detecting on-line state of feeding loop in tobacco processing process

Abstract

The invention discloses a system and method for detecting the on-line state of a feeding loop in the tobacco processing process. The system comprises a feeding pipeline pressure detection sensor, a feeding loop flow meter, a feeding front belt scale, a PLC, a feeding loop early warning system and a warning output module. A short-term early warning judgment module, a long-term early warning judgment module and a pipeline pressure early warning judgment module which are sequentially connected are arranged inside the feeding loop early warning system. The feeding loop early warning system is used for analyzing faults probably occurring in a pipeline in a short term or a long term on a feeding system, and gives out early warning prompts for the regular faults. The warning output module is used for outputting short-term warning signals, long-term warning signals and pipeline pressure warning signals. Early warning of the state of equipment is conducted according to the health coefficients of the feeding loop of the system, the maintenance cleaning frequency and the regular repair frequency of the equipment can be adjusted, and the mean time between faults of the equipment is increased.

Description

technical field [0001] The invention relates to an online state detection system and detection method of a feeding loop in a tobacco processing process. Background technique [0002] With the rapid development of industry, various enterprises have begun to use Total Normalized Production Maintenance (TnPM) to ensure the normal operation of equipment in order to achieve the highest overall equipment effectiveness (OEE). Preventive maintenance is the premise and guarantee for carrying out comprehensive and standardized production maintenance. Preventive maintenance refers to the early detection and early treatment of equipment abnormalities from the standpoint of preventive medicine, and strives to reduce the failure rate of the equipment itself, shorten the repair time, and prolong the service life, thereby improving the performance of the equipment and reducing maintenance operations. cost. Therefore, it is urgent to establish a set of equipment online early warning mechan...

Problems solved by technology

[0003] The technical problem urgently needed to be solved by those skilled in the art is: at present, the feeding equipment in the tobacco industry only calculates the instantaneous feeding amount according to the material weight and feeding ratio of the scale before feeding to apply spices, but does not analyze the long-term operation of the feeding system. And provide early warning prompts for regular faults
