{Abstract}: In magnetic resonance examination, the interaction between implants and the radio frequency (RF) fields induces heating in human tissue and may cause tissue damage. To assess the RF-induced heating of implants, three steps should be executed, including electromagnetic model construction, electromagnetic model validation, and virtual human body simulations. The crucial step of assessing RF-induced heating involves the construction of a test environment for electromagnetic model validation. In this study, a hardware environment, comprised of a RF generation system, electromagnetic field measurement system, and a robotic arm positioning system, was established. Furthermore, an automated control software environment was developed using a Python-based software development platform to enable the creation of a high-precision automated integrated test environment. The results indicate that the electric field generated in this test environment aligns well with the simulated electric field, making it suitable for assessing the RF-induced heating effects of implants.<BR>在磁共振检查中，植入物与射频场相互作用会引起周围人体组织发热，甚至造成组织损伤。评估植入物射频热效应需要进行植入物电磁建模、电磁模型验证和虚拟人体仿真。其中，构建用于电磁模型验证的测试环境是射频热效应评估的重要环节。研究建立了包括射频发生系统、电磁场量测系统和机械臂定位系统的硬件环境，使用基于Python的软件开发平台实现了自动化控制软件环境，形成了高精度、自动化的集成测试环境。研究结果表明，该测试环境形成的电场与计算机仿真得到的电场具有较好的一致性，可以用于植入物射频热效应评估。.
