Hazardous chemical cylinders use large-capacity, dispersed, high-risk mobile pressure vessels; low entry threshold for filling operations, weak safety management measures; frequent accidents and serious consequences.The management status is not taken by the electronic label technology before the bottle body adopts the etching number; the qualified mark adopts the paper label. The collection, filling, distribution and inspection information are all manually collected and the accuracy of the entry is poor. The major problem is the safety management of cylinders have not been tracked dynamically; there is a lack of traceability of the quality about filled gas. Solution is use the bottle uniquely identified by an electronic tag and is monitored by electronic tags throughout the life of the cylinder.

Hazardous Chemicals Gas Bottle Electronic Label Identification Solution

Management status

Before adopting electronic label technology, the bottle body is etched with a marking; the qualified mark is a paper label. The collection, filling, distribution and inspection information are all manually collected and the accuracy of the entry is poor. The major problems is the safety management of cylinders.

In order to solve the problem, the bottle is uniquely identified by an electronic tag, and the tag is managed using an electronic tag throughout the life of the cylinder.

Explosion protection requirements

Meets GB 3836.1 and reaches Ex ibIICT4 rating

Operating system

After the tag is initialized, the unique identification code (ID) of the tag chip, the cylinder registration code recorded on the surface of the tag, and the etched number (steel number) of the cylinder are bound and written into the tag.

Data binding process

Establish a basic information database of gas cylinders, and the data items meet the requirements for gas cylinder management;

By using a handheld reader, the basic information of the cylinder that needs to be recorded in the label is written into the electronic label attached to the bottle; Transfer the ID number of the label to the enterprise back-end database, and together with the basic information of the cylinder recorded in the label; The background database generates a record of the cylinder etch number, the tag ID number, the cylinder usage registration code, and the associated cylinder information.

The cylinder information stored in the label, at least:

cylinder etched number

cylinder manufacturing date

filling medium

latest inspection date

information such as the date of the next inspection

Gas cylinder recycling

The reader reads the basic information stored in the electronic tag, determines the legality of the cylinder, and writes the recycling mark and date to the electronic tag.

The cylinder recovery record is generated in the reader and transmitted to the enterprise back-end database. The data includes the cylinder etch number, label serial number, gas medium, user/site information, recovery date, and recycle operator number.

Filling Pre-filling inspection

The reader reads the basic information stored in the electronic tag, determines the legality of the cylinder, and writes the recycling mark and date to the electronic tag. The cylinder recovery record is generated in the reader and transmitted to the enterprise back-end database.Generate a check report of the cylinder before filling. 

The reader reads the basic information stored in the electronic tag, determines whether the cylinder is qualified, and writes the filling information to the electronic tag.

Generate a cylinder filling record in the reader and transfer it to the enterprise back-end database.

Generate a cylinder filling record report. Check after filling

The reader reads the basic information stored in the electronic tag, determines whether the cylinder is qualified, and writes the result of the inspection after filling and the number of times of filling to the electronic tag.

Generate a cylinder filling record in the reader and transfer it to the enterprise back-end database.

Check the record report after the cylinder is filled.

Distribution

Update the historical delivery record through the reader (there are 5 historical delivery records), enter the delivery site/direct user code and write the electronic tag.

The cylinder delivery record is generated in the reader and transmitted to the enterprise back-end database.

Inspection

The filling unit will send the cylinders adjacent to the inspection date recognized by the reader to the inspection station. The inspection station inspects the cylinder and writes the inspection results to the label.

An inspection record is generated in the reader and transmitted to the inspection organization back-end database. The inspection station feedback the results of the cylinder inspection back to the filling company.

In the gas cylinder statistics, statistics of cylinder distribution from delivery to home to recycling. Report that generates statistics

Gas cylinder electronic label application standardization

The application standardization of gas cylinder electronic tags mainly involves three aspects:

Gas cylinder uniform coding

Label performance, packaging, data storage format within the tag chip

Reader and tag communication, certification, and explosion protection requirements of the body

The gas cylinder code follows the coding rules stipulated in the technical documents of the General Administration of Quality Supervision, Inspection and Quarantine of TS 4501—2005;

The method code specified in EPC, EN-UCC or ISO 21007 is not used. The above code is electronically encoded as a gas cylinder product for gas packaging. With the EPC or ISO 21007 standard, the cylinder manufacturer must apply to the ISO designation authority for the manufacturer code, and the registration agency must register with the ISO designation body.

In particular, ISO 21007 does not make any provision for the handling of job information data such as cylinder filling, inspection, and distribution.

In the gas cylinder electronic label industry standard regulations, we decided to continue to use the TS-501-2005 regulations, and at the same time, apply to the domestic OID registration agency for the gas cylinder electronic tag object identifier. Label requirements

According to the application requirements, the physical characteristics of the label, environmental adaptability, anti-counterfeiting characteristics, and packaging requirements shall be specified; the information data format in the storage label shall be specified.

Due to the vast territory of China, the climate varies greatly from north to south. For the application of ambient temperature standards to distinguish between alpine regions and general regions, the minimum temperature adaptability requirements are specified.

In addition, the standard will also focus on:

Label anti-transfer requirements;

Metal shield and control the amplitude of frequency drift;

he storage format of the data file can be selected as follows:

Ø Fixed-length organization to establish application partitions

Ø Indefinitely long organization, can build directory area

Reader special requirements

Specify adaptability in specific climates, biological environments, chemically active substances, and mechanical vibration environments;

The reader shall specify its explosion-proof requirements and anti-corrosion requirements from the aspects of the outer casing, structure, internal components, and battery characteristics;

Explosion-proof grade regulations;
