Abstract

The invention relates to a battery swap action control system based on a central processing unit and a programmable logic device. Control instructions and configuration information are written by the central processing unit to a master control programmable logic device and are then distributed by the master control programmable logic device to corresponding sub-control programmable logic devices, so as to control mechanical and electrical equipment within a battery swap station; the central processor and the master control programmable logic device communicate through a GPMC parallel bus, and the master control programmable logic device and the sub-control programmable logic devices are in serial fiber communication based on Manchester encoding, such that a higher transmission rate and anti-jamming performance are gained and the real-time performance and reliability of information transmission are ensured; and the sub-control programmable logic devices are independent of each other in software, hardware, machinery and electrical aspects, with no direct information interaction, which allows the system to have high flexibility in upgrading and maintaining. Compared with a traditional PLC way, the invention greatly reduces the cost of hardware.

Description

technical field [0001] The invention relates to the field of electric vehicle battery replacement, in particular to a battery replacement action control system based on a central processing unit and a programmable logic device. Background technique [0002] In recent years, environmental pollution has become increasingly serious, oil resources have been depleted, and fuel vehicles are facing severe challenges. The society has also turned its attention to electric vehicles. The car provides a good power-on experience is an important factor affecting the future development and popularization of electric vehicles. [0003] Among the many power-on methods, the power-swapping method is a fast, convenient and safe method. The battery swap station is composed of a parking platform, a battery replacement trolley, a battery storage rack, a battery compartment lift, and other auxiliary equipment. The battery swap process requires the cooperation of these components to complete, and e...
