Method and device for monitoring energy consumption abnormity

Abstract

The invention discloses a method and a device for monitoring energy consumption abnormity. The method comprises the following steps: monitoring an energy consumption parameter of a current period of a vulcanization process in a tyre manufacturing process; according to the value of the energy consumption parameter of the current period obtained through monitoring, obtaining an energy efficiency monitoring value and an energy efficiency predicting value of the current period of the vulcanization process in the tyre manufacturing process; according to the obtained energy efficiency predicting value and a preset confidence coefficient, obtaining the energy efficiency prediction interval of the current period; when the energy efficiency monitoring value is beyond the energy efficiency prediction interval, determining that abnormity occurs in the energy consumption of the current period of the vulcanization process in the tyre manufacturing process. The method and the device can provide reasonable monitoring for complex and variable energy consumption situations in the industrial production process, missing detection and false detection are reduced, and the precision of energy consumption abnormity monitoring is improved.

Description

technical field [0001] The invention relates to the technical field of energy monitoring, in particular to a method and device for monitoring abnormal energy consumption in the vulcanization process in the tire manufacturing process. Background technique [0002] In manufacturing enterprises, energy is often wasted due to some abnormal energy consumption events, such as steam or compressed air leakage caused by pipeline damage, gas leakage caused by aging valves, etc. These abnormal events are difficult to find, and the accumulated energy waste However, it is very large, so it is of practical value to study the abnormal monitoring method of energy consumption. [0003] The existing technology mainly uses the threshold comparison method to monitor abnormal energy consumption, that is, the energy consumption threshold and the range of the energy consumption threshold are set in advance, and then the production is judged according to whether the monitored energy consumption dat...
