This article according to the tripping device external guidance system the performance index request, proposed the tripping device external guidance system overall plan, including instruction code and radio frequency decoding and radio frequency transmission plan. In arranges in the decoding plan, in view of the tripping device system work characteristic, designed the unique remote control command ---40 bit serial to move the position code hardwood form and the code, and has designed the code and the decoding electric circuit. In in the radio frequency transmission system ` choice, this article according to the instruction-code baseband signal the frequency spectrum characteristic, has analyzed in several kind of typical binary radio frequencies transmission system band width and harms the code performance, had determined in the PCM/FM discriminator demodulation radio frequency transmission system band width and harms the code performance, had determined the PCM/FM discriminator demodulation radio frequency transmission plan, and confirmed through the channel computation above chooses the plan.
