Embodiment Construction

[0059] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0060] Such as figure 1 As shown, the online status detection system of the feeding loop in the tobacco processing process includes:

[0061] The feeding pipeline pressure detection sensor is installed in the feeding pipeline and is used to collect the pressure value of the feeding pipeline;

[0062] Feeding circuit flowmeter, installed in the feeding pipeline, used to measure the instantaneous feeding amount;

[0063] The belt scale before feeding is installed in front of the feeding machine to collect the output value of the feeding pump;

[0064] The PLC controller receives the data collected by the feeding pipeline pressure detection sensor, the feeding loop flowmeter and the belt scale before feeding, and the output end of the PLC controller is connected with the alarm output device; the PLC controller is responsible for the possible failure of ...

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...
