The invention discloses a multifunctional protection method for loading and unloading operation of a container truck, which comprises the following steps of: forming a hardware system by using a plurality of digital cameras and an artificial intelligence controller, connecting the plurality of digital cameras with the artificial intelligence controller, establishing a circularly stored signal queue for an input lifting appliance control PLC (Programmable Logic Controller) signal by the system, by combining and analyzing the current PLC semaphore and the backtracking of the stored signal queue, the system can automatically judge whether the unloading operation or the loading operation is currently carried out, and the system calculates the three-dimensional positions of three types of interested objects including a truck head, truck tray corners and a container in images shot by a plurality of digital cameras in real time, so that the deviation from the standard position is calculated, and the real-time positioning of the interested objects is realized. Therefore, truck protection is realized. The system can intelligently distinguish the truck load condition and the tray type and complete real-time quantitative calculation, the system is slightly influenced by the environment, the misjudgment rate is low, and the loading and unloading efficiency of the container truck can be effectively improved.

    本发明公开了一种用于集装箱卡车装卸作业的多功能保护方法,本方法使用多个数字相机和人工智能控制器构成硬件系统,所述多个数字相机和人工智能控制器连接,所述系统对输入的吊具控制PLC信号,建立循环储存的信号队列,通过结合分析当前PLC信号量和已储存信号队列的回溯,系统可以自动判断当前是卸车还是装车作业,系统实时计算多个数字相机所拍摄图像中的卡车车头、卡车托盘边角和集装箱这三类感兴趣物体的三维位置,从而计算与标准位置的偏差,以实现卡车保护。本专利能够智能分辨卡车负载情况和托盘种类,并完成实时定量计算,系统受环境影响小,误判率低,并可以有效提高集装箱卡车装卸作业的效率。
