Data processing method in recognition system. |
摘要 |
<p>A recognition system including a data carrier which is attached to a moving article and which has a memory storing identification data of the article and a control system communicating with the data carrier without any contact therebetween. The control system includes a higher-level controller, a plurality of lower-level controllers connected thereto, and read/write heads connected to the lower-level controllers. The higher-level controller sequentially sends an auto read/write command to the lower-level controllers. In response thereto, when the data carrier approaches one of the lower-level controllers, the lower-level controller communicates with the data carrier so as to access the memory thereof. The lower-level controller temporarily keeps a result of the memory access (the response from the data carrier) such that on receiving a command from the higher-level controller, the lower-level controller transmits the memory access result thus temporarily kept therein to the higher-level controller.</p> |
