1. Scheme principle:
1. Each tent is equipped with a reader. The address of each reader represents a tent and location.
2. Each tag is installed on the shelf. When the tag enters the tent, it is recognized by the reader installed in the tent, indicating that the tag enters the tent. When the tag leaves the tent, the reader cannot recognize the tag, indicating that the tag has been Leave the tent.
3. The working principle of the tag is to actively transmit signals to the reader.
2. The technology of this project 2.45 will have the following problems during the use process.
1. The tags in several consecutive tents may be read by readers in adjacent tents.
In such a situation, we can’t judge that the label is in that tent.
Solution: When the tag is in use, register it, and set the tag and its matching reader/writer in the software. The purpose is: when the tag is working, although it is recognized by multiple readers, it will only be read and displayed by the reader in the tent.
2. If you follow the above method to operate, but manual operation may cause errors, use the label that should be used in the tent-1 number in the tent-8. In this way, some tags do not display data even though they are read and written during normal reading and writing. Therefore, it is necessary to develop an error correction function.
Solution: The software can specify which readers to work or all work, and the data of the tags will all be displayed. At the same time, the software will handle it. When the tag is registered, which reader should be recognized by it. It is now being used by those readers. If there is a mismatch, an alarm will be prompted. This can correct errors.
