请看下面一段代码
%%%%%%%%%%%%%%%%%%% MOBILE TOWER %%%%%%%%%%%%%%%%%%%%%
\newcommand{\MBS}[1]{%
\begin{tikzpicture}[]
\node[station] (base) {#1};
%\draw[line join=bevel] (base.110) -- (base.70) -- (base.north west) -- (base.north east) -- cycle;
\draw[line join=bevel] (base.100) -- (base.80) -- (base.110) -- (base.70) -- (base.north west) -- (base.north east);
\draw[line join=bevel] (base.100) -- (base.70) (base.110) -- (base.north east);
% original yshift=.8pt
%\draw[line cap=rect] ([xshift=.5cm,yshift=.3pt] base.north) [antenna=1];
%\draw[line cap=rect] ([yshift=.3pt]ant1 |- base.north) -- node[above,shape=rectangle,inner ysep=+.3333em]{\dots} ([xshift=-.5cm,yshift=.3pt]base.north) [antenna=2];
\draw[line cap=rect] ([xshift=-.1768cm,yshift=.6pt]base.north -| base.right tail) [antenna=1];
\draw[line cap=rect] ([yshift=.6pt]ant1 |- base.north) -- node[above,shape=rectangle,inner ysep=+.3333em]{\dots} ([xshift=.1768cm,yshift=.6pt]base.north -| base.left tail) [antenna=2];
%\draw[line cap=rect] ([yshift=.3pt]ant1 |- base.north) -- ([xshift=-.5cm,yshift=.3pt]base.north) [antenna=2];
%\node at ($(ant1)!0.5!(ant2)$) {\dots};
\end{tikzpicture}
}
它允许我编写如下命令
\draw (-4,0) node[scale=2]{\MBS{a}} ;
并生成一个中心带有标签“a”的图形（在无线通信中，这种图形指的是移动塔）。现在下面的代码
%%%%%%%%%%%%%%%%%%%%%% RELAY %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\tikzset{radiation/.style={{decorate,decoration={expanding waves,angle=90,segment length=4pt}}},
relay/.pic={
code={\tikzset{scale=5/10}
\draw[semithick] (0,0) -- (1,4);% left line
\draw[semithick] (3,0) -- (2,4);% right line
\draw[semithick] (0,0) arc (180:0:1.5 and -0.5);
\node[inner sep=4pt] (circ) at (1.5,5.5) {};
\draw[semithick] (1.5,5.5) circle(8pt);
\draw[semithick] (1.5,5.5cm-8pt) -- (1.5,4);
\draw[semithick] (1.5,4) ellipse (0.5 and 0.166);
\draw[semithick,radiation,decoration={angle=45}] (1.5cm+8pt,5.5) -- +(0:2);
\draw[semithick,radiation,decoration={angle=45}] (1.5cm-8pt,5.5) -- +(180:2);
}}
}
允许我编写如下代码
\path (2,-1.2) pic[scale=0.5,color=red] {relay};
它会生成一个中心没有标签的图形（好奇的人可能会认为这是无线通信中的中继）。如何实现类似于第一个示例（移动塔）的中心自定义标签？
下面的代码给出了一个完整的工作示例。
