1、 Get to knowRFIDtechnology

RFID positioning tags are one of the products that customers consult more about explosion-proof certification.RFIDIn recent years, electronic tags based on positioning principles have been widely used in the fields of personnel positioning and equipment and facility positioning due to their long transmission distance, simple and reliable circuit, small size, and low cost. For example, fields such as animal chips, car chip anti-theft devices, access control, parking lot control, production line automation, material management, etc.

Radio Frequency Identification（RFID），Radio Frequency IdentificationThe abbreviation is a type of automatic recognition technology. It performs non-contact bidirectional data communication through wireless radio frequency, using wireless radio frequency to read and write recording media (electronic tags or radio frequency cards) to achieve the purpose of identifying targets and exchanging data. It is considered to be21One of the most promising information technologies of the century.

IIRFIDAnalysis of Explosion proof Certification Technology for Positioning Labels

According to national safety production andExplosion proof standardIt is required that electrical and non electrical equipment used in explosive hazardous areas must pass the testing and certification of relevant national explosion-proof standards, obtain corresponding explosion-proof testing reports and certification certificates before they can be put into market application. Applied to explosive sitesRFIDThe positioning tag must also be approved by the countryExplosion proof certificationTechnical requirements.

So for explosion-proof certification of this type of positioning tag, there are mainly the following technical requirements:

1. For active positioning tags, battery selection is crucial. The battery should be able to pass throughGB/T 3836If the short-circuit performance of the battery is not up to standard and the thickness of the pole pieces does not meet the requirements, it is difficult for the battery to pass the short-circuit test, and explosion prevention cannot be discussed.

2. The energy of a circuit is generally pureRFIDActive electronic tags, their capacitors should be in themHLevel, therefore its circuit energy often does not become a barrier to certification for such products.

3. The electrical clearance and creepage distance of circuit boards vary according to different explosion-proof levels, so it is not advisable to arrange the components on the circuit board too densely.

4. Shell, whether used for personnel positioning or equipment and facility positioning, more manufacturers tend to make non-metallic shells, which can reduce weight and cost. Therefore, when using non-metallic shells, anti-static issues must be considered. In the process of shell production, adding anti-static agents to the shell material can easily solve this problem.

Having achieved the above four points, oneRFIDThe explosion-proof certification of the positioning tag can be obtained.

IIIRFIDWhat explosion-proof types can positioning tags be used for?

RFID positioning tags are generally used for tracking and positioning in places with high security, with small size and low powerIntrinsic safety typeMostly. Most of themiboricExplosion proof rating is sufficient.
