The Galactic plane scanning survey is one of the main scientific objectives of the Hard X-ray Modulation Telescope (known as Insight-HXMT). During the two-year operation of Insight-HXMT, more than 1000 scanning observations have been performed and the whole Galactic plane ($0^{\circ }<\mathrm{l}<{360}^{\circ }$, $-{10}^{\circ }<\mathrm{b}<{10}^{\circ }$) has been covered completely. We summarize the Galactic plane scanning survey of Insight-HXMT for two years, including the characteristics of the scanning data, the data analysis process and the preliminary results of the Low-Energy telescope, the Medium-Energy telescope and the High-Energy telescope. With the light curve PSF fitting method, the fluxes of the known sources in the scanned area as well as the flux errors are obtained for each scanning observation. From the relationships of SNRs and fluxes, the 5σ sensitivities of three telescopes of Insight-HXMT are estimated as $\sim 7.6\times {10}^{-11}{\text{erg cm}}^{-2}{\text{s}}^{-1}$ ($3\text{mCrab},1-6\text{keV}$), $\sim 4.0\times {10}^{-10}\text{erg}{\text{cm}}^{-2}{\text{s}}^{-1}$ ($20\text{mCrab},7-40\text{keV}$) and $\sim 2.6\times {10}^{-10}{\text{erg cm}}^{-2}{\text{s}}^{-1}$ ($18\text{mCrab},25-100\text{keV}$) for an individual scanning observation of $2-3\text{h}$, respectively. Up to September 2019, more than 800 X-ray sources with various types are monitored by the three telescopes and their long-term light curves with three energy bands are obtained to make further scientific analyses.

银河平面扫描调查是硬X射线调制望远镜（称为Insight-HXMT）的主要科学目标之一。在Insight-HXMT的两年运行期间，已执行了1000多次扫描观测，整个银河平面（$0^{\circ }<\mathrm{升}<{360}^{\circ }$， $-{10}^{\circ }<\mathrm{b}<{10}^{\circ }$）已被完全覆盖。我们对Insight-HXMT的银河平面扫描调查进行了总结，包括扫描数据的特性，数据分析过程以及低能望远镜，中能望远镜和高能望远镜的初步结果。使用光曲线PSF拟合方法，可以为每个扫描观测获得扫描区域中已知源的通量以及通量误差。从信噪比和通量之间的关系，5个σ的三个望远镜灵敏度洞察力HXMT被估计为$〜7.6\times {10}^{-11}{\text{厘米}}^{-2}{\text{s}}^{-\mathrm{1个}}$ （$3\text{螃蟹}，\mathrm{1个}-6\text{keV}$）， $〜4.0\times {10}^{-10}\text{尔格}{\text{厘米}}^{-2}{\text{s}}^{-\mathrm{1个}}$ （$20\text{螃蟹}，7-40\text{keV}$）和 $〜2.6\times {10}^{-10}{\text{厘米}}^{-2}{\text{s}}^{-\mathrm{1个}}$ （$\mathrm{18岁}\text{螃蟹}，25-100\text{keV}$）用于 $2-3\text{H}$， 分别。截至2019年9月，三台望远镜监测了800多种不同类型的X射线源，并获得了它们在三个能带的长期光曲线，以进行进一步的科学分析。
