Vibrational noise signal due to wind force on the electronic fence security system need to be overcome. Sensor cables were already fast fixed on to existing security fence perimeter. The wind noises generated by the strong wind were much problem by the real operation of electronical fence system. Wind noise signals receiving from sensor cables were processed and analyzed to improve the existing program in the DSP (TMS320F2812) microcontroller. The system collects signal amplitude, duration time and frequency spectrum to distinguish the wind effect from intrusion signal. The result gives the real or false alarm. Frequency analysis was done for each duration of N=128 samples of input signal was using special algorithm of the fast Fourier transform through DSP microcontroller. The security system has been tested at border lines of Mongolia. A detection rate after apply the developed algorithm for reducing false alarms was improved up to 94%~95% of reliable accuracy for real field application.
