摘　　要：乡村电网规模不断增长,变电站巡检工作成为电网运行管理的重要组成部分。然而,由于农网变电站分布广且监督机薄弱,部分农网变电站巡检作弊问题频发,伪造巡检记录或巡检外包等现象突出,影响到乡村企业和居民的经营生产和日常生活。基于此,本文聚焦低成本数字化巡检监督终端研究,基于ESP32和OV2640构建轻量级人脸识别算法,采用集成LTE CAT.1和GNSS的移远EG810M模组,辅以本地化人机交互系统,实现巡检信息的无纸化记录和远程投递。实验表明,本文构建的巡检监督终端具有较高的性价比,适合在农网变电站应用场景中批量推广。The scale of rural power grids continues to grow, and substation inspection work has become an important component of power grid operation management. However, due to the wide distribution of rural power grid substations and weak supervision mechanisms, some rural power grid substa-tions have frequent problems of inspection cheating, such as forging inspection records or out-sourcing inspection, which affects the operation, production, and daily life of rural enterprises and residents. Hence, this paper focuses on the research of low-cost digital inspection and supervision terminal, which uses ESP32 and OV2640 to build a lightweight face recognition algorithm, and adopts a teleportation EG810M module integrating LTE CAT.1 and GNSS to achieve paperless re-cording and remote delivery with help of a human-machine interaction system. The experiment shows that the inspection and supervision terminal proposed in this paper has high cost-effectiveness and is suitable for mass promotion in the application scenarios of rural power grid substations.
