Use RFID technology to manage fishing boat personnel in and out

Principle: After the tag enters the magnetic field, it receives the RF signal from the reader, and uses the energy obtained by the induced current to send out the product information (Passive Tag, passive tag or passive tag) stored in the chip, or actively sends a certain frequency. Signal (Active Tag, Active Tag or Active Tag); After the reader reads the information and decodes it, it sends it to the central information system for relevant data processing.

RFID technology implementation analysis

1) Using UHF technology

When the personnel is not very dense, the area is relatively wide, and the tag will not be obstructed by other personnel (such as personnel entering the attendance area in turn), and at the same time sensitive to costs, 915MHz RFID can be used, which has the following advantages:

* Realize long-distance card reading, according to different models of products can read 0-10 meters of tag information, so as to achieve long-distance automatic attendance;

* The label is light in weight, and employees can wear it on the tag;

* The label adopts passive design and has a long service life;

* There are many types of labels, and the cost is low;

* The reader has strong anti-collision ability and can identify multiple tags at one time.

The reading distance can meet the requirements, but UHF has disadvantages. When UHF tags worn by workers are blocked, they may miss reading.

2) using 2.45GHz technology

When the application is crowded and the tag will be blocked by the human body, 2.4GHz or 433MHz RFID can be used. This system has the following advantages:

* The tag is battery-powered, and the distance recognized by the reader is longer, which can be adjusted from 0-100 meters;

* It has strong penetrating ability and is not affected by being blocked by the human body. The label can be placed in the bag, pocket, etc .;

* Strong anti-collision ability, can recognize more than 500 labels at one time.

The distance from 0 to 100m can be adjusted, and the distance can be controlled flexibly through the on-site conditions. Active tags worn by workers in the reading area of the reader can be identified as long as they are not sealed with all-metal shielding boxes.
