3. self-walking intelligent automatic cycle as claimed in claim 1 rotates natural rain irrigation sprinkler, it is characterised in that described long-range
Control terminal is smart mobile phone or notebook computer.
4. self-walking intelligent automatic cycle as claimed in claim 2 rotates natural rain irrigation sprinkler, it is characterised in that FPGA module
Also include guidable FPGA configuration circuit, the guidable FPGA configuration circuit connection IOC；It is described can
The FPGA configuration circuit of guiding includes serial FLASH memory；FCLK, FnCS, FMOSI, FMIS of serial FLASH memory connect
Mouth connection ppu；Configuration information is written to by serial FLASH memory by above-mentioned interface；Interface CLK, SDA connection are outer
Portion is handled；Guidance information is set by above-mentioned interface；NConfig, DI, DCLK, nCS, DO connect FPGA by wire.
5. self-walking intelligent automatic cycle as claimed in claim 1 rotates natural rain irrigation sprinkler, it is characterised in that described serial
The data of FLASH memory are written as：Ppu is completed configuration information by FCLK, FnCS, FMOSI, FMIS and write；
The guidable FPGA configuration circuit bootup process includes：After nConfig signals are effective, FPGA will enter again
The process of configuration.FPGA can export DI, DCLK and be combined with nCS signals, and sequential detector is when detecting specific sequence, sequence
The output of detector causes " 2 select 1 module " output to come from " guidance information cache module "；Sequential detector be not detected by it is specific
Sequence when, " 2 select 1 module " export directly from FPGA DI；
After ppu completes the input of guidance information by CLK, SDA, nConfig can be caused effective, while will guiding
Information is written to " guidance information caching " module, and after nConfig signals are effective, then cause FPGA configuration process；
If ppu is not operated by CLK, SDA, the information default that is preserved in " guidance information caching " module and
The guidance information of DI outputs is consistent.
6. self-walking intelligent automatic cycle as claimed in claim 1 rotates natural rain irrigation sprinkler, it is characterised in that the control
System is also built-in with the signal processing module for entering line translation to the signal of reader transmission；The conversion side of the signal processing module
Method includes：
Nonlinear transformation is carried out to reception signal s (t), carried out as follows：
