To address the common drawbacks of current disinfection robots, which include the potential for secondary environmental pollution, disinfection dead corners, and low efficiency, in this paper, an autonomous mobile combination disinfection system is proposed. The system utilizes ultraviolet (UV) radiation and a low-concentration hydrogen peroxide aerosol to kill pathogens. It comprises three parts: a human-computer interface, a mobile robot, and disinfection equipment. A disinfection process model with continuous and fixed-point modes was established, and the effective disinfection range, speed, and duration were quantitatively calculated. The developed prototype was tested on-site by a professional third-party testing agency. The experimental results demonstrated that the combination disinfection robot achieved a 92.95% disinfection rate of natural airborne bacteria in a room measuring 22 square meters with a height of 2.8 m in just 30 min. The disinfection efficiency is at least 25% higher compared to standalone UV lamp disinfection and also exhibits a noticeable improvement over standalone hydrogen peroxide aerosol disinfection. The system enables the environmentally friendly, rapid, efficient, and all-encompassing disinfection of natural airborne bacteria. Finally, various disinfection solutions and recommendations for different application scenarios and requirements are provided.
为了解决当前消毒机器人存在的二次环境污染、消毒死角和效率低等常见问题，本文提出了一种自主移动组合消毒系统。该系统利用紫外线（UV）辐射和低浓度过氧化氢气溶胶来杀死病原体。它由三部分组成：人机界面、移动机器人和消毒设备。建立了连续和定点模式的消毒过程模型，定量计算了有效消毒范围、速度和持续时间。开发的原型由专业的第三方测试机构进行了现场测试。实验结果表明，在一个 22 平方米、2.8 米高的房间内，组合消毒机器人仅用 30 分钟就实现了对自然空气中细菌的 92.95%的消毒率。与单独使用紫外线灯消毒相比，消毒效率至少提高了 25%，与单独使用过氧化氢气溶胶消毒相比，也有明显的提高。该系统实现了对自然空气中细菌的环保、快速、高效、全面的消毒。最后，针对不同的应用场景和需求，提供了各种消毒解决方案和建议。
