1. a method that realizes the information exchange between portable type information switching unit comprises transmit legAnd the recipient, it is characterized in that, comprise the steps:

  • (1) sending direction sends broadcast packet outward, comprises match information and pet name parameter in the broadcast packet, and system is in idle condition;

    Whether (2) recipient receives broadcast packet, judge and oneself mate;

    If match information is identical, then be judged as Condition Matching, obtain the user'"'"'s pet name in the broadcast packet, select simultaneously clean channel, modified address and send details to respond bag, these details are responded the pet name that comprises pre-channel number, amended address, synchronization character and the transmit leg of jumping of parameter band, and enter the pre-receiving state, wait for the other side'"'"'s echo;

    If have no reply at the appointed time, then get back to idle condition;

    If match information is not identical, then do not do any response, system still is in idle condition;

    (3) " be the local pet name, then send the echo of receiving details response bag, system enters pre-transmission state, according to modified address, the address parameter of receiving after transmit leg receives that details are responded bag, to check the parameters " pet name;

    (4) after the recipient receives that details are responded the echo of bag, whether match address is correct, correct then send the order begin now to send data, and order the other side enters the transmission state immediately to send data, oneself also enters accepting state immediately, waits for the other side'"'"'s packet;
