Let the function $f(x)=e^{x}+a\sin x+b$.
- $(1)$ When $a=1$ and $x\in[0,+\infty)$, $f(x)\geqslant 0$ always holds, find the range of $b$;
- $(2)$ If the tangent line of $f(x)$ at $x=0$ is $x-y-1=0$, and the equation $f(x)= \frac {m-2x}{x}$ has exactly two solutions, find the range of the real number $m$.
