Abstract: A tag collision preventing method in a wireless frequency identification system is provided to determine all the tags in an RF field, efficiently and rapidly by utilizing advantages of an existing binary tree protocol and query tree protocol and adopting a new collision preventing protocol. A tag collision preventing method in a wireless frequency identification system comprises the following several steps. A reader sends a start signal via plural tags in a standby state(S1), converts a current mode of each tag into a listening mode(S2), and transmits data by each tag. A current mode of the tag, which is the same as the data transmitted by the reader, is converted into a sending mode(S3) and a current mode of the tag, which is different from the data transmitted by the reader, is converted into the standby mode. If a stop signal is transmitted by the reader and the data sent by the tag is not the final bit, a current mode of the tag is converted into the listening mode again and the tag prepares for receipt of new data. If the stop signal is not transmitted by the reader, the tag sends the next bit of the bit previously sent, and if the bit sent by the tag is the final bit, a current mode of the tag is converted into a killed mode(S4).

Abstract: An oxygen control method of catalytic converter for vehicle is provided to remove oxygen stored in WCC and UCC and to reduce nitrogen oxides by obtaining oxygen storage capacities when a state of fuel is changed from Rich to Lean or from Lean to Rich, and obtaining exact fuel spray amount by multiplying oxygen storage capacity when the state of fuel is changed from Rich to Lean by fuel addition/reduction factor. An oxygen control method of catalytic converter for vehicle includes the steps of determining whether fuel cut occurs, (a)determining whether air amount of a warm-up catalytic converter(WCC) is larger than oxygen storage capacity(OSC) of the WCC, (b)determining whether air amount of under-flower UCC is larger than oxygen storage capacity(OSC) of the UCC when air amount of the WCC is larger than OSC of the UCC in the step(b), spraying fuel to the WCC and UCC with a value obtained by multiplying the OSC by fuel addition/reduction factor when the air amount of UCC is larger than OSC of the UCC in the step(c), the OSC is the value when the state of fuel is changed from Rich to Lean, receiving a sense signal from an oxygen sensor provided between the WCC and UCC and spraying fuel until an oxygen output value becomes higher than a reference value.
