Tikz：制作 S 形箭头以避开节点

Question

我正在尝试制作一个 S 形箭头来避开图中的节点。我可以放一个角，但不知道如何放多个。我尝试过这个答案但无法用我的代码进行编译。

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{positioning,shapes,arrows, calc}


\tikzstyle{startstop} = [rectangle, rounded corners, minimum width=3cm, minimum height=1cm,text centered, draw=black]
\tikzstyle{io} = [trapezium, trapezium left angle=70, trapezium right angle=110, minimum width=3cm, minimum height=1cm, text centered, draw=black]
\tikzstyle{process} = [rectangle, minimum width=3cm, minimum height=1cm, text centered, draw=black]
\tikzstyle{decision} = [diamond, minimum width=3cm, minimum height=1cm, text centered, draw=black]
\tikzstyle{arrow} = [thick,->,>=stealth]

\begin{document}


\begin{tikzpicture}[node distance=1cm]
\node (start) [startstop] {Camera};
\node (Transmitter) [process, right =of start] {Transmitter};

\node (Receiver) [process, below =of start, yshift = -2cm] {Receiver};
\node (Computer) [process, right =of Receiver] {Computer};

\node (Field) [process, below =of $(start)!0.5!(Transmitter)$] {Field};



\draw [arrow] (start) -- (Transmitter);
\draw [dotted] (Transmitter) |- (Receiver);

\draw [arrow] (Receiver) -- (Computer);
\draw[arrow]  (Field) -> node[left]{}($(start)!0.5!(Transmitter)$); 


\end{tikzpicture}

\end{document}

Answer 1

像这样吗？

我刚刚将|-和连接器与和节点-|之间的一个点一起使用。以下是完整代码：startComputer

\documentclass[tikz, border=5mm]{standalone}

\usetikzlibrary{positioning,shapes,arrows, calc}

\tikzstyle{startstop} = [rectangle, rounded corners, minimum width=3cm, minimum height=1cm,text centered, draw=black]
\tikzstyle{io} = [trapezium, trapezium left angle=70, trapezium right angle=110, minimum width=3cm, minimum height=1cm, text centered, draw=black]
\tikzstyle{process} = [rectangle, minimum width=3cm, minimum height=1cm, text centered, draw=black]
\tikzstyle{decision} = [diamond, minimum width=3cm, minimum height=1cm, text centered, draw=black]
\tikzstyle{arrow} = [thick,->,>=stealth]

\begin{document}

\begin{tikzpicture}[node distance=1cm]
\node (start) [startstop] {Camera};
\node (Transmitter) [process, right =of start] {Transmitter};

\node (Receiver) [process, below =of start, yshift = -2cm] {Receiver};
\node (Computer) [process, right =of Receiver] {Computer};

\node (Field) [process, below =of $(start)!0.5!(Transmitter)$] {Field};

\draw [arrow] (start) -- (Transmitter);
%\draw [dotted] (Transmitter) |- (Receiver);

\draw [arrow] (Receiver) -- (Computer);
\draw[arrow]  (Field) -> node[left]{}($(start)!0.5!(Transmitter)$);
\draw[rounded corners, arrow] 
    (Receiver.north) |- ($ (start)!0.7!(Computer) $)
                      -| (Transmitter.south);

\end{tikzpicture}

\end{document}
