We present the CCD observations and light and radial velocity curves analysis for the eclipsing binary system AG LMi. Three minimum times of light curves were determined and used to calculate the orbital period’s value as 1.3590$\pm$0.0001 days and a new epoch of the system as 2458141.2040$\pm$0.0002 days. The observed B, V, and R light curves and radial velocity (RV) data from Nelson (2020) were combined and incorporated into a new simultaneous analysis using the Wilson-Devinney code. The combined photometric and spectroscopic solutions indicate that the system is a detached eclipsing binary system that consists of two similar components with a mass ratio of $q\sim 0.983$. The spectral type of each component was estimated as F8, and the effective temperatures of components were calculated as $T_1=6240\pm 19$ K and $T_2=6220\pm 21$ K for the primary and secondary stars, respectively.

我们展示了日食双星系统 AG LMi 的 CCD 观测以及光和径向速度曲线分析。确定光变曲线的三个最小次数并用于计算轨道周期值为1.3590$\pm$0.0001 天和系统的新纪元 2458141.2040$\pm$0.0002 天。将观察到的 B、V 和 R 光变曲线以及来自 Nelson (2020) 的径向速度 (RV) 数据结合起来，并使用 Wilson-Devinney 代码合并到新的同步分析中。结合光度和光谱的解决方案表明，该系统是一个分离的日食双星系统，由质量比为$q～0.983$. 每个组件的光谱类型估计为F8，组件的有效温度计算为${吨}_1=6240\pm 19$ K 和 ${吨}_2=6220\pm 21$ K 分别代表主星和次星。
