reader collision 中文意思是什麼
reader collision
解釋
解讀器沖突-
When multiple tags are transmitting data simultaneity within reader ' s scope, that will occurs a collision. in order to resole this problem, we must use multiple access protocols
在射頻識別系統中的閱讀器作用范圍內，有多個應答器應答要求通信而發生碰撞問題。 -
The research contents of this paper includes as follows : firstly, design a new type reader based on ti s6700 reader ic and try to enhance the reading distance through adding power amplifier ; secondly, adopt the idea of gpio simulation to produce spi timings to drive s6700. secondly, overcome the shortcoming of general mcu spi port ; thirdly, design the rs232 / rs485 full duplex conversion module, mmi interface in the system ; fourthly, analyze the rfid system communication protocol iso15693 and find out the working processes and realization of the instruction ; lastly, discuss the communication safety and accidental factors including the checkout and collision design, illustrate the realization of crc and anti - collision arithmetic theory
本論文的主要研究內容包括: （一）設計基於s6700閱讀器晶元的新型閱讀器，通過使用對中高頻閱讀器外加功率放大模塊的方法，實現較遠距離通信。 （二）採用單片機通用口三線模擬的方法模擬通用spi口時序，克服其不可位操作的缺點，實現對s6700的驅動。 （三）在rfid系統中集成設計了rs232 / rs485通訊模塊、液晶顯示模塊等，著重說明了其軟硬體實現方法。 -
Superfluous commands which go beyond the framesize between reader and tags are avoided. further more, the protocol process module in dsp of a rfid system according to epc gen2 has been designed based on the above work. and then the tag analog software for testing the conformance especially the anti - collision process for reader is completed
在以上研究的基礎上，進行了基於epcgen2標準的閱讀器的開發工作，與同事合作設計了dsp中的協議處理模塊，並獨立設計和編寫了標簽模擬軟體中的協議處理模塊，對閱讀器的協議一致性，尤其是防碰撞流程進行測試。
