Problems solved by technology

Its disadvantage is that because phosphine gas has a corrosive effect on metal copper, the long-term use will cause damage to the signal line, and the controllers supported by manufacturers on the market usually have no communication interface, or only have MODBUS protocol, or due to the non-standard nature of the protocol, Not easy to integrate into host computer system

Abstract

The present invention belongs to the cigarette production field and relates to a cigarette packet comprehensive process parameter on-line monitoring system. The cigarette packet comprehensive process parameter on-line monitoring system includes a sampling gas transmission unit, a phosphine monitoring device, a temperature, humidity and oxygen content monitoring device, a blowing unit, a sampling exhaust unit, a PLC unit, a man-machine interface unit , a phosphine leak gas sampling sensor and a remote monitoring system. The system of the invention can monitor the concentration of a phosphine gas as well as the temperature, humidityand and oxygen content parameters of cigarette packets in real time in a cigarette packet storage process. The cigarette packet comprehensive process parameter on-line monitoring system has the advantages of simple structure, easy operation and safe use.

Description

technical field [0001] The invention relates to the field of cigarette production, in particular to an online monitoring system for comprehensive process parameters of cigarette packs. Background technique [0002] At present, in the process of killing insects in cigarette packs, the measurement of phosphine concentration is usually divided into high concentration and low concentration detection according to the concentration range. Usually low concentration (0-20ppm) phosphine gas in the environment uses a portable monitor. The disadvantage is that manual measurement is required according to the monitoring location, and generally manual data recording is required, and measurement results cannot be continuously recorded electronically. The measurement of high concentration (0-20ppm) phosphine gas in the pesticide operation area usually uses a sensor transmitter in the dangerous area to transmit the signal to the dedicated controller placed in the supporting safe area, and t...
