将“text-block”添加到 \sbBloc

Question

我对 TiKz 和 schemabloc 包还不熟悉。我想知道两件事：(1) 如何向 \sbBloc 添加“文本块”，如下图所示（这是我尝试复制的图像）；(2) 如何在 schemabloc 中绘制 T_d(s) 信号？提前致谢！

我的代码在这里：

输出结果如下：

Answer 1

为了回答第一个问题，我使用了rectangle split节点样式：

\documentclass{article}
\usepackage{amsmath}
\usepackage{mathptmx}
\usepackage{tikz}
\usetikzlibrary{shapes}
\usepackage{schemabloc}

\begin{document}
\begin{tikzpicture}[node distance=2cm]
    \sbStyleBloc{rectangle split,rectangle split parts=2,align=center}
    \sbEntree{E}
    \sbComp*{a}{E}
    \sbBloc{pacemaker}{Pacemaker \nodepart{second} $\dfrac K{\frac1{12}s+1}$}{a}
        \sbRelier[]{E}{a}
        \sbRelier[]{a}{pacemaker}
    \sbSumh*[5]{c}{pacemaker}
        \sbRelier[]{pacemaker}{c}
    \sbBloc{heart}{Heart \nodepart{second} $\dfrac1s$}{c}
        \sbRelier[]{c}{heart}
    \sbSortie{S}{heart}
        \sbRelier[]{heart}{S}
    \sbDecaleNoeudy[6]{S}{U}
        \sbBlocr{sensor}{Rate measurement \\ sensor \nodepart{second} $K_m=1$}{U}
\sbRelieryx{heart-S}{sensor}
\sbRelierxy[]{sensor}{a}
\end{tikzpicture}
