Overview

Equipment Overview

This UHF reader is a device installed in a conveyor in a rotating sushi store and reading a UHF RF tag attached to a sushi plate flowing at the top. By reading the sushi plate constantly using RFID, it is possible to manage freshness and manage the sales situation of each sushi item in real time.

The normal operation of the UHF reader is controlled by a command from the host to raise the EPC of the sushi plate that rolls on the conveyor to the reading host. There is no data transmission when there is no sushi plate, but a response is periodically returned in the sense of KEEP ALIVE. As another function, after the sushi plate passes through the dishwasher, it has an output terminal for reading the tag and sorting the plate, and using the classification signal output from the external terminal, the sorter attached to the dishwasher can separate the dishes.

This UHF reader is a specified low power radio station under the Radio Law. Since the wireless certification has been obtained, there is no need to register or license a wireless station to use it, and it can be used immediately after purchase.

Basic functions

The UHF reader has the following basic functions:

1. UHF band RF tag reading
   It has a function to read an RF tag in accordance with ISO / IEC 18000-63 (EPCglobal Class 1 Generation 2) by a command from the host. The area of the tag to be accessed is the EPC area.
   If there is no tag or reading of the tag fails for any reason, the data is not sent and it proceeds to the next reading operation.
   If there is no continuous tag reading, a response will be returned within 2 seconds in the sense of KEEP ALIVE.

2. LED indicator
   The operating state of the UHF reader can be inferred from the LED indicator and the lighting state.
   There are three types of LED indicators: “POWER LED”, which indicates that the power is on, “Communication(㏻ಙ) LED”, which indicates the reading status of the UHF reader, and “RESERVE LED,” which is reserved and can be lit as a software in the future. Each LED can change lighting specification by software change.

3. Firmware update function
   Firmware update is performed by connecting a dedicated debugger to the connector inside the case.
   When updating the firmware, basically we will send back in our company.

4. Shipping inspection function
   There are no special functions for shipping inspection of products, and inspections are performed using ordinary commands.

5. Sushi tray sorting external output terminal
   Reads data from sushi plate tag and outputs 4-bit TTL level.

Internal configuration

The main parts that make up this product are shown below.

Table 2-4 Board Configuration

Other microcomputers, power supply circuits, LEDs, and external output terminal blocks are mounted.
UHF module| A board with an RF tag read / write function.
Antenna| Antenna to access the RF tag.
AC adapter| AC adapter that supplies DC power to the main unit.
There is no power switch on the main unit, so plugging the AC adapter into the main unit turns on the power.

Tag reading method

When reading and writing tags, hold the tag over the reader as shown below.

The reader antenna is linearly polarized, so the tag direction is read according to the polarization direction. Please note that the reading distance will be drastically reduced when the IC tag is cross polarized or perpendicular to the antenna surface (the direction shown in the figure below).

See Fig. 3-3 for the polarization image.

Reading distance varies depending on the surrounding environment and Tag specifications.
If the Tag cannot be read even under the above conditions, the location may be a null point.
If the distance from the IC tag is around several centimeters, reading may improve

Other notes

• The reading of the RF tag to be used should be thoroughly tested, and the placement of the RF tag and the UHF reader should be placed at a sufficient reading distance. UHF readers are affected by the surrounding environment. Be especially careful with metals.

• This product does not have a waterproof structure, so be careful when installing it in a place where it will be exposed to water droplets.

• Bundle the cables of the AC adapter cord and the external output terminal so that they do not hang around the antenna. It may affect the reading of RF tags.

• About maintenance
  If it gets dirty, wipe it with a soft, dry cloth. If the stain is severe, immerse the cloth in a mild detergent diluted with water, squeeze it well, wipe it off, and finish with a dry cloth.

• About lighting of use environment Some fluorescent light fixtures generate noise and affect the reader’s reading. Hf type fluorescent lamps are driven at high frequency by an inverter, and it has been confirmed that the reading distance decreases when used near. Please be careful when installing the leader.
