Design of Weighing and Charging System Based on"Loongson"
In order to respond positively to the development of information and innovation applications and the demand of localization of core devices,this paper introduces a design scheme of weighing and charging system.The Loongson 1B chip is used as the main control chip,and the LVGL library writes a graphical operation interface to drive it.The overload threshold,charging unit price,vehicle information and other parameter information can be modified and displayed through the LCD screen,and functions such as IC card charging and release can be realized after weighing.Through self-made embedded system function board,external integrated module and expansion module,the relevant design functions are simulated in the laboratory environment.
