RFID electronic tag manufacturers carry out industrial anti-interference for RFID industrial readers and writers 123
There are many interference factors in the industrial environment that can affect normal information recognition. Although RFID technology can achieve non-contact recognition and ignore environments such as oil and dust, it is still affected by factors such as current, vibration, and electromagnetic signals. To ensure the normal operation of RFID equipment, effective anti-interference measures need to be taken.
What are the interfering factors in industrial scenarios?
1. Radio frequency interference:
There are also some wireless communication devices in the industrial environment, such as radios, mobile phones, etc., which may cause radio frequency interference with RFID devices, leading to signal transmission errors.
2. Electromagnetic interference:
There are a large number of electromagnetic devices in the industrial environment, such as electric motors, frequency converters, welding machines, etc., which may generate electromagnetic interference and affect the signal transmission of RFID industrial readers and writers.
3. Mechanical vibration interference:
The mechanical equipment in the factory workshop may generate vibrations during operation, which may have an impact on the reading and writing processes of RFID industrial readers.
4. Same frequency interference:
When two or more adjacent transmitting stations transmit multiple channels, it is possible to use the same frequency. Due to factors such as frequency accuracy and stability of the transmitter, there may be slight differences between the transmitting carrier frequencies. Therefore, when the user receives the main signal, they will also receive another interference signal.
5. Configuration interference:
When encountering configuration interference, network cables can be used for detection and identification, and network cables can be used to achieve access to wireless access points.
6. Hardware interference:
If the quality of hardware devices is poor, slow transmission speed often occurs.

How can RFID industrial readers and writers resist interference?
The RFID industrial reader adopts advanced anti-interference technology,
Including digital signal processing, anti-interference antennas, multipath recognition, etc., to enhance the anti-interference ability of the equipment.
1. Adopting advanced digital signal processing technology, filtering out cluttered signals in the environment through algorithms, improving signal-to-noise ratio, and effectively resisting interference.
2. Adopting a special anti-interference antenna design, with a reasonable antenna structure, it has the ability to reflect signals. When external interference signals enter the antenna, the antenna will reflect these signals back, thereby reducing the impact of interference signals on the antenna.
3. Adopting multipath recognition technology, using multiple readers or antennas to receive signals, improving the accuracy and anti-interference ability of device recognition by identifying signals from different paths.
4. Use anti-interference tags, increase tag size, narrow the distance between tags and readers, and enhance the anti-interference ability of readers.
5. By optimizing the reading and writing methods of tags to reduce interference, for example, during the tag reading process, the reader/writer can use frequency hopping communication technology to avoid conflicts with surrounding devices; During the label writing process, the reader can use slot allocation technology to ensure the stability and reliability of data transmission.
