Description: 因RS-485接口具有良好的抗噪声干扰性，长的传输距离和多站能力等上述优点就使其成为首选的串行接口。因为RS485接口组成的半双工网络，一般只需二根连线，所以RS485接口均采用屏蔽双绞线传输。RS485接口连接器采用DB-9的9芯插头座，与智能终端RS485接口采用DB-9（孔），与键盘连接的键盘接口RS485采用DB-9（针）。(RS-485 interface has the advantages of good noise immunity, long transmission distance and multi station capability, which makes it the preferred serial interface. Because the RS485 interface consists of half duplex network, generally only two connections are needed, so the RS485 interface is shielded twisted pair transmission. RS485 interface connector adopts DB-9's 9 core plug socket, and the intelligent terminal RS485 interface adopts DB-9 (hole), keyboard interface with keyboard, RS485 adopts DB-9 (needle).)

Description: Particle Swarm Optimization (PSO) is a newly-emerging heuristic global search algorithm based on swarm intelligence and it searches the global optimal point in the complex search space through the competition and collaboration of the particles; however, PSO is easy to get trapped in local extremum, to have premature
convergence or stagnation. In order to help PSO strike a balance between individual diversity and swarm convergence, this paper proposes an artificial immune PSO based on clonal selection. It integrates the advantages of artificial immunity and PSO and introduces the idea of immunity in PSO, namely to add immune operator in PSO so as to make PSO a new algorithm with the function of immunity.

Description: An important feature of FM and PM is that they can provide much better protection to the message against the channel noise as compared to the linear (amplitude) modulation schemes. Also, because of their constant amplitude nature, they can withstand nonlinear distortion and amplitude fading. The price paid to achieve these benefits is the increased bandwidth requirement; that is, the transmission bandwidth of the FM or PM signal with constant amplitude and
which can provide noise immunity is much larger than 2W , where W is the
highest frequency component present in the message spectrum.
