The low cost, the high intellectualization's electronic scale has and the broad market prospect without doubt. The electronic scale collection machine, the electricity, the meter ina body, have multi-purpose, the high accuracy, fast and the dynamic measurement, stable reliable and soon characteristics, has represented the weighing apparatus product development direction. The mercial system requests it tobe able to supply each kind of sales message, the weighing and the management automation close union, causes the weighing, the valuation, to enter the storehouse, the sales management integration, realizes the management automation. This request electron valuation scale can with the electronic accounting working, composes the weighing system and puter system plete integrated control system, provides the powerful support for the mercial trade physical distribution's high efficiency development. B ased on above need, this article has designed one kind the electronic scale which and the PC machine munication procedure manufactures using the MCS-51 monolithic integrated circuit, through used VB to manufacture the weight data acquisition system, may weight information which gathered on the PC machine direct-viewing observation a
