Detailed Description
The following description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings to describe the technical solutions of the present invention in detail, but not to limit the present invention to the scope of the embodiments described.
As shown in fig. 1, the method for allocating a free interconnection channel in wireless data communication of the present invention ensures that two rf transmitters in a wireless data communication free interconnection device operate in different channels, thereby ensuring that no rf interference occurs inside the device.
The specific working process is as follows:
the wireless uplink data communication module searches the wireless signal quality on each wireless data communication channel around, and the MCU selects a channel with the minimum wireless channel interference to be allocated to the wireless data communication downlink channel for use;
secondly, considering that interference can be brought when the downlink transmitter works, the MCU controls the downlink transmitter to work, then the wireless uplink data communication module searches channels, and the MCU determines the wireless data communication downlink channels;
and thirdly, isolating the uplink data channel and the downlink data channel of the wireless data communication.
It should be understood by those skilled in the art that the radio frequency interference can be solved through channel isolation and channel optimization, and the channel allocation method provided by the present invention is to implement channel isolation and channel optimization of the wireless data communication free interconnection device.
Those skilled in the art will appreciate that the channel allocation rules established to prevent radio frequency channel interference can minimize the radio frequency interference locally, and radio frequency interference occurring in the networking.
Example 1:
the method for allocating the free interconnection channel in the wireless data communication of the embodiment comprises the following specific steps:
s101a, scanning channel occupation and interference conditions one by an uplink channel;
s102a, the uplink channel reports the scanning result to the MCU;
s103a, the MCU allocates a channel to the downlink channel according to the scanning data;
s104a, opening a radio frequency channel for working by a downlink channel;
s105a, the uplink channel scans the channel occupation and interference condition one by one again;
s106, the MCU 106a synthesizes the twice scanning data to give an optimal channel to the downlink channel;
and S107a, forbidding the uplink channel and forbidding the uplink channel to use the channel of the downlink channel.
