Scheme Design for Cargo Loading Control System of Cargo Plane

Due to the late start of China’s civil aviation, the research on cargo loading control system of air freighter is less, and there is no research and development system and technical ability at present, so the research on related technology of loading control system is imminent. Aiming at the above problems, this paper studies the key technologies of CAN communication network design, software design and control hardware design of controller, and puts forward a design scheme of cargo loading system controller for large cargo aircraft. Firstly, based on the analysis of the composition of the loading control system and the requirements of loading and unloading, the basic function design requirements of the control system controller are proposed. Secondly, aiming at the characteristics of a large number of CAN communication nodes, a large amount of data transmission and high real-time requirements of the loading control system, a three-layer CAN communication network with sub-regional control is proposed to ensure the communication requirements and operation efficiency of the controller. On this basis, the hardware implementation scheme of dual MCU is proposed, and the application layer software design is based on an embedded real-time operating system. And the visualization function of PDU status and ULD real-time position is realized by using a serial display. The scheme proposed in this paper has a significant reference value for the automation and domestication of cargo loading control systems.
