Abstract

The invention aims to provide a method for identifying liquid materials, which comprises the following steps: firstly, posting RFID (Radio Frequency Identification Device) labels on plastic drums by utilizing the RFID technology so as to identify the liquid materials with different trade marks; secondly, acquiring information of the current production trade marks by utilizing the MES (Manufacturing Execution System), reading information of the RFID trade marks in the field by adopting a radio frequency reader-writer at the same time, and comparing the information of the current production trade marks and the information of the RFID trade marks; finally utilizing an automatic control system to put the liquid materials meeting the requirements and in the plastic drums through the PLC (Programmable Logic Controller) into a material tank. The method provides a solution to add flavors and fragrances into a cigarette primary processing line of the tobacco industry, avoids the adding of wrong liquid materials caused by manual errors, and completely eradicates quality accidents.

Description

A kind of method of identifying the liquid material

Technical field

The present invention relates to informationization and automation field, is a kind of method of identifying the liquid material specifically.

 

Background technology

Tobacco business primary processing line perfuming, charging process are to influence the important procedure that tobacco inhales flavor, the tobacco leaf of the different trades mark or spices or the essence that pipe tobacco applies different formulations, therefore, spices or the essence with corresponding brand coupling is applied on tobacco leaf or the pipe tobacco just particularly important.

Present stage, at the cigarette primary processing line, the feed liquid of perfuming, the employed different brands of charging process is to utilize the Plastic Drum splendid attire basically, is distinguished the various brands feed liquid at bucket external application literal, numeral or code.When producing, add pan feeding cylinder (scene applies usefulness) by artificial feed liquid with corresponding brand, this process may add the pan feeding cylinder owing to the feed liquid of manually slipping up mistake, causes feed liquid to apply mistake, causes serious quality accident.

 

Summary of the invention

In sum, the object of the present invention is to provide a kind of method of identifying the liquid material.

The objective of the invention is to realize by following technology:

A kind of method of identifying the liquid material may further comprise the steps:

A. utilize the hand-held read write line that cigarette trade mark information is write in the RFID label;

B. put up the RFID label of the different trades mark at the Plastic Drum of splendid attire feed liquid, be used for the trade mark and distinguish;

C. computer obtains worker's odd numbers of current production by the MES server;

E. frequency read/write reads the RFID label information, compares with the information that the c step obtains;

When f. the information obtained of the information that reads when frequency read/write and MES server is consistent, frequency read/write output 24VDC high level, input PLC when PLC obtains 24VDC, allows to carry out the components and parts action, carries out suction;

G. the information that reads when frequency read/write and MES server obtain information inconsistency the time, frequency read/write is not exported the 24VDC high level, when PLC did not obtain 24VDC, the warning device prompting was reported to the police, and did not allow to carry out the components and parts action, did not allow suction.

The present invention at first utilizes the RFID technology, put up the RFID label at Plastic Drum, in order to distinguish the feed liquid of the different trades mark, secondly, utilize the MES system to obtain current production trade mark information, simultaneously read the RFID label information with frequency read/write at the scene, two information are compared, the feed liquid of finally utilizing automation control system will compare in the satisfactory Plastic Drum is controlled the charging absorption pump material cylinder of packing into by PLC.

Wherein, RFID is the abbreviation of the English (Radio Frequency Identification) of REID, and the MES system makes to carry out management system.

Advantage of the present invention and beneficial effect:

1, the present invention provides a kind of solution for tobacco business primary processing line essence and flavoring agent applies, utilize the RFID technology, put up the RFID label at Plastic Drum, in order to distinguish the feed liquid of the different trades mark, automatically identify destination object and obtain related data by radiofrequency signal, avoid having stopped quality accident because of the wrong liquid feeding material of artificial error, the work of wherein identifying need not manual intervention, can work in various adverse circumstances.

2, the present invention can directly install at the reinforced perfuming Control Server of tobacco business, does not influence the server operation during installation, and Installation and Debugging are simple, use safety, and response is fast, can satisfy daily production needs.

 

Description of drawings

Fig. 1 is system assumption diagram of the present invention.

 

The specific embodiment

The present invention will be further described below in conjunction with accompanying drawing:

As shown in Figure 1, a kind of method of identifying the liquid material may further comprise the steps:

A. utilize the hand-held read write line that cigarette trade mark information is write in the RFID label;

B. put up the RFID label of the different trades mark at the Plastic Drum of splendid attire feed liquid, be used for the trade mark and distinguish;

C. computer obtains worker's odd numbers of current production by the MES server;

E. frequency read/write reads the RFID label information, compares with the information that the c step obtains;

When f. the information obtained of the information that reads when frequency read/write and MES server is consistent, frequency read/write output 24VDC high level, input PLC when PLC obtains 24VDC, allows to carry out the components and parts action, carries out suction;

G. the information that reads when frequency read/write and MES server obtain information inconsistency the time, frequency read/write is not exported the 24VDC high level, when PLC did not obtain 24VDC, the warning device prompting was reported to the police, and did not allow to carry out the components and parts action, did not allow suction.

Embodiment

At first, by manually utilizing hand-held read write line KMOM-LZ2900A-F6C that cigarette trade mark information is write among the RFID label KMOM-LZTF-8029-90-55;

Put up the RFID label of the different trades mark at the Plastic Drum of splendid attire feed liquid, be used for the trade mark and distinguish;

Computer obtains worker's odd numbers of the current production cigarette trade mark by the MES server;

Computer reads the RFID label information by frequency read/write KMOM-LZRF-860, compares with the worker's odd numbers that obtains from the MES server;

When the information that the information that reads when frequency read/write and MES server obtain is consistent, frequency read/write output 24VDC high level, input PLC when PLC obtains 24VDC, allows the charging absorption pump suction;

During information inconsistency that the information that reads when frequency read/write and MES server obtain, frequency read/write is not exported the 24VDC high level, and when PLC did not obtain 24VDC, the alarm lamp flicker did not allow the charging absorption pump suction.
