The network terminal includes:
Data transfer request judgment module, to include sewing machine ID and preset receive the sewing machine
After the data transfer request for priority of being engaged in, according to pre-set task stack list, judges whether to send to allow to transmit and order；
Data transmission module, to pass through described the after data transfer request judgment module transmission allows to transmit and order
The data of the transmission of sewing machine described in one CPCH reception.
9. a kind of sewing machine, it is characterised in that: communicated by the first channel and the second channel with the network terminal, the sewing
Machine includes the radio-frequency module for the frequency hopping between first channel and second channel, the sewing machine no data into
When row transmission, it is in the second channel, the sewing machine includes:
Task generation module, to generate data transfer task；
Whether condition judgment module, the second channel after receiving the data transfer task, to judge the sewing machine are empty
Spare time, if it is not, and repeating the judgement movement；If so, generating idle instruction；
Data transfer request module, in the free time for receiving the data transfer task and condition judgment module transmission
After instruction, data transfer request is sent to the network terminal by second channel, the data transfer request includes institute
State sewing machine sewing machine ID and preset task priority；
Task status broadcast module passes through described the to after receiving the allowing to transmit and order of network terminal feedback
It is in progress that the two channel overall situations broadcast the data transfer task；And to pass through first channel in the sewing machine
After completing data transmission, frequency hopping is the second channel, and is terminated by the second channel overall situation broadcast data transfer task；
Data transmission module is broadcasted the data transmission by the second channel overall situation in the task status broadcast module and is appointed
Do honest work it is underway after, the sewing machine frequency hopping is transmitted to the first channel, and by first channel to the network terminal
Data.
10. sewing machine according to claim 9, which is characterized in that the network terminal includes a double frequency communication radio frequency mould
Block or two single-frequency communication radio frequency modules are to realize the communication of first channel and the second channel.
11. a kind of multi-machine communication system based on radio frequency, including the network terminal as described in any one of claim 5~6, and
Including sewing machine as claimed in claim 7；Alternatively, including the network terminal as claimed in claim 8, and wanted including such as right
Sewing machine described in asking any one of 9~10.
