The invention discloses a cooling and heating alternating automatic unmanned trolley device which comprises a trolley body, the trolley body is installed on driving wheels, a front side magnetic sensor is installed on the front side of the lower end of the trolley body, a rear side magnetic sensor is installed on the rear side of the lower end of the trolley body, and an upward camera and an upward RFID reader-writer are installed at the upper end of the trolley body. A downward camera and a downward RFID reader-writer are installed at the lower end of the vehicle body, and a laser radar is installed at the front end of the vehicle body. The method is characterized in that the problem of visual laser optical sensing failure generated when the automatic unmanned trolley enters a cold temperature difference large area is solved, the magnetic sensor and the RFID reader-writer are connected with the optical sensor so that the trolley can continuously complete work without stop, and when visual recognition of a target object fails under the severe condition, the automatic unmanned trolley can be automatically recognized. The magnetic sensor and the RFID reader-writer are not influenced by the environment to stably identify the target object, the corresponding automatic action is continued to be completed, and the function of the visual sensor is quickly recovered through the vehicle-mounted air blowing device.
本发明公开了一种冷热交替自动无人小车装置,包括车体,所述车体安装在驱动轮上,所述车体下端的前侧安装有前侧磁传感器,所述车体下端的后侧安装有后侧磁传感器,所述车体上端安装有朝上摄像头、朝上RFID读写器,所述车体下端安装有朝下摄像头、朝下RFID读写器,所述车体前端安装有激光雷达。本发明的特点是:解决了自动无人小车进入冷温差大区域产生的视觉激光光学类传感失效的问题,磁传感器、RFID读写器接续光学类传感器可继续让小车不停歇的继续完成工作,并且可以在恶劣情况下目标物视觉类识别失效时,磁传感器、RFID读写器不受环境影响稳定识别目标物,继续完成相应自动化动作,并通过车载吹风装置快速让视觉类传感器恢复功能。
