Embodiment Construction
[0017] The implementation of the present application will be further described below with an embodiment. The embodiment of the present application provides a wireless data transmission method, including 1 master, n slaves, n is a natural number, the method includes: S10 : The host sends downlink wireless data packets to n slaves. Wherein, the downlink wireless data packet carries downlink response information, and the downlink response information is used to inform the slave whether the uplink wireless data packet sent by the master has been received, so that the slave determines whether to resend the uplink wireless data packet according to the downlink response information; S11： The master receives the uplink wireless data packet sent by the slave. Wherein, the uplink wireless data packet carries uplink response information, and the uplink response information is used to inform the host whether the downlink wireless data packet sent to the slave is received by the slave; S...

The invention discloses a wireless data transmission method, a host computer and slave computers and belongs to the field of wireless data transmission. The method includes the steps that the host computer transmits downstream wireless data packets to the n slave computers, wherein downstream response messages are carried in the downstream wireless data packets; the host computer receives upstream wireless data packets transmitted from the slave computers, wherein upstream response messages are carried in the upstream wireless data packets; and the host computer judges whether to retransmit the downstream wireless data packets according to the upstream response messages. The hose computer comprises a transmitting module, a receiving module and a judging module. Each slave computer comprises a first acquisition module, a first processing module, a recording module, a first transmitting module and a storage module. Through the utilization of the wireless data transmission method, the host computer and the slave computers, the probability of accepting the wireless data packets can be improved, and the transmission efficiency of the wireless data packets will not be reduced.
Description
technical field [0001] The present application relates to the field of wireless data transmission, in particular to a wireless data transmission method, a master and a slave. Background technique [0002] With the development of communication technology, wireless data packet transmission has been widely used, and wireless data packet transmission has become a research hotspot. At present, the commonly used wireless data packet transmission mode is the non-response transmission mode, and the non-response transmission mode includes two forms, one is to send only once, and the other is to send multiple times. [0003] In the existing wireless data packet transmission method, the wireless data packet method of sending only once and no response cannot guarantee that the receiving end can receive the wireless data packet sent by the sending end, and the reliability of wireless data packet transmission is low; The wireless data packet data transmission of no response can increase ...
