Abstract

The invention relates to a synergistic immunity detection method for a steam leakage of a steam trap of a tire vulcanizing machine based on a computer artificial system. The synergistic immunity detection method comprises the following steps: A: initialization of a computer host system is carried out; to be specific, (1) by establishing a dynamic baseline regression model between the steam level at the workshop level and the equipment level, a dynamic hazard baseline is generated, and a hazard threshold is set; (2) the state parameters of vulcanizing machine and the state parameters of steam pipe are used and the detector of leakage vulcanizing machine is generated by artificial immune network clustering; B: Synergistic immune detection method of computers running at each time is that the dynamic baseline regression model and the detector are performed synergistic immunity detection. The synergistic immunity detection method can accurately detect whether or not the steam leakage event exists in the steam trap of the vulcanizing machine; the omission rate and the error detection rate are respectively controlled at 2.62% and 5.26%, compared with the traditional device level state parameter detection methods, the omission rate rate and the error detection rate are reduced by 6.67% and 14.28% respectively.

Description

technical field [0001] The invention relates to the technical field of steam trap internal leakage detection, in particular to a cooperative immunological detection method for steam trap internal leakage of a tire vulcanizing machine. Background technique [0002] In the tire vulcanization workshop, the raw tire is shaped into a finished tire with specified shape, high strength and high elasticity under high temperature and high pressure. Steam is the most commonly used heat source and pressure medium in the vulcanization process. A large amount of steam consumption leads to high costs in the vulcanization process. Energy consumption cost and environmental pollution cost; and internal leakage of steam trap (hereinafter referred to as internal leakage of steam trap) is a common abnormal event in the vulcanization workshop, which often leads to a large amount of steam waste and reduces the energy efficiency of vulcanization; The steam consumption during the working process of ...

AI Technical Summary

Problems solved by technology

However, the internal leakage of the steam trap causes the steam to be discharged in a non-condensed state, resulting in a waste of energy

Due to technical and cost constraints, few single vulcanizers are equipped with steam meters, and it is difficult to find faults through simple observation

In actual production, workshops generally rely on regular manual inspections (disassembly or leak detectors) to find faults, but it takes a long time and is inefficient

The internal leakage of the steam trap does not affect the production in a slight state, and many enterprises do not even realize the seriousness of the internal leakage of the steam trap

However, some researchers suggest that the internal leakage of traps be included in the scope of pipeline leakage, and detect faults by analyzing state parameters such as temperature, pressure, flow rate, vibration and sound waves around potential leakage points, although leakage can be found in a short time faults, and more accurately locate the leak point, but the state parameter detection method is only effective for transmission pipeline systems with simple shapes and stable flow rates, and it is difficult to apply to vulcanization workshops with complex pipeline topologies and unstable flow rates

[0004] For internal leaks of steam traps, using energy efficiency assessment to identify them requires equipment-level energy consumption measurement support, which is what most tire manufacturing companies lack. However, the development of an effective detection method for this problem still needs to overcome the following three difficulties: the limitation of equipment-level measurement, the accuracy of energy efficiency assessment, and the disturbance factors of vulcanizer temperature and pressure; namely (1 ) Due to the cost and process, equipment-level steam metering is difficult in the vulcanization workshop, especially the steam blocking effect of the steam flowmeter will affect the precise control of the vulcanization temperature and pressure. Usually, the vulcanizer is not equipped with steam metering, only equipped with steam chamber and The temperature and pressure sensors of the bladder do not have the conditions to rely on the change of the steam consumption of a single vulcanizer for leak detection; (2) The energy efficiency of vulcanization is affected by factors such as production speed, process parameters, and ambient temperature, so it is easy to set threshold detection for the energy efficiency of the workshop This fault will lead to high false detection rate and missed detection rate, and it is impossible to locate the leaking vulcanizer; (3) The disturbance of steam source pressure and steam flow rate will cover up the change of steam temperature and pressure caused by the internal leakage of the trap, which can be used independently Changes in the temperature and pressure of the vulcanizer to detect this fault will also result in a high false detection rate and missed detection rate

Therefore, under the existing metering conditions, the effective detection of the internal leakage of the trap cannot be realized simply by evaluating the process parameters and energy efficiency.
