Circuit design of electronic weighing system

The electronic document is a "live" template. The various components of your paper are already defined on Electronic Scale is a kind of equipped that with electronic weighing scale device, also widely used in commercial sales, from the 20th century, the mid-60\´s analog electronic scale simulation of the development and production, experienced a simulated electronic scales, digital electronic scales and electronic scales computer in three stages, functions including setting various parameters, automatic processing and gross weight, net weight, tare weight and tired of the show, such as value-added Parameter settings in order to manage and convenience comes with the top computer serial communication interface. In this paper, quantitative-oriented packaging weighing control, both at home and abroad from the design of programmable weighing controller, weighing given programmable controller design options and technical indicators, based on the C8051F020 development of a single enhanced weighing the programmable machine controller, this article gives a detailed weighing controller design method, according to the ingredients of the technological requirements of production the use of single-chip microprocessor design, integrated set of new measurement and control weighing controller for automatic weighing, batching control and on-line monitoring and control, have a high cost performance, and have a perfect programmable functions, is a set weight control, programmable control, weighing in one transmission to facilitate the realization of precise control of complex multi-function weighing controller. Batching Controller is designed with the high reliability, strong anti-interference ability, cost-effective and compact size, full-featured and so on, it can be used as a stand-alone instrument, and it can be used as embedded instrumentation through the RS-232 a standard interface with the top 485 industrial units in conjunction with networks.
