基于AT89S52单片机的装载称重控制器设计

Design of load weighing system using AT89S52 single chip Microcomputer

给出了以AT89S52为核心,利用单片机的运算和控制功能,并采用串口液晶显示模块实时显示所测货物的重量和累计重量装载称重控制器设计方案。同时该方案还提供将装卸货物的单车量、日累加量、总累加量以无线通讯方式传输至上位机,供上位机显示和处理的功能。

A load weighing system for freight truck is designed using the operation and control functions of the AT89S52 single chip micro- computer （ SCM ）. The tandem LCD is adopted to display the meas- ured freight weight and accumulative weights. This system can also use wireless transmission technique to transfer and display the load- ing and unloading freight of a truck, its daily accumulative freight and total accumulative freight onto the upper server for data processing.
