本文介绍了一种以MSP430单片机微处理器最小系统,并配以几个主要的集成电路器件设计成的智能电子秤。该电子秤使用压力传感器采集当前压力,根据输入单价,准确计算出物品的金额,并将重量和金额显示在液晶显示屏上。此外,该电子秤还能分析压力超过范围,并发出超重提示。由于压力传感器已广泛应用于各行各业,特别是随着微处理机的出现以及工业生产自动化程度的提高,它已成为各种过程控制中必不可少的装置之一。 目前,电子计价秤的使用非常普及,逐渐会取代传统的杆秤。以压力传感器制作的电子秤已广泛地应用到各行各业,特别是随着微处理机的出现,工业生产过程自动化程度的不断提高,压力传感器已成为过程控制中的一种必需的装置。本文介绍的电子秤采用MSP430单片机微处理器设计,结合了几个主要的集成电路器件,实现了智能化的功能。 关键字:压力传感器,放大器,单片机 Abstract Nowadays, electronic steelyard is very popular and it will gradually replace the traditional steelyard. The electronic steelyard made by the pressure transducer has been applied to all professions, especially with the emergence of the microprocessor. With the increasing automation of industrial production, the pressure transducer becomes an essential device in the process control. This text introduces an intellectual electrical system controlled by MSP430 and consists of several integrated circuits. This system gathers the pressures by the pressure sensor according to the price input, calculates the price accurately, and displays the weight and the money on the LCD. It also can analyze when the pressure exceeds the range, and issues a warning for overweight. In conclusion, this article introduces a smart electronic scale designed with MSP430 microprocessor and several main integrated circuit devices. This system uses a pressure sensor to collect the current pressure, accurately calculates the amount of the goods based on the input unit price, and displays the weight and amount on the LCD. It can also analyze pressure readings that exceed the range and issue overweight prompts. As pressure transducers are widely used in various industries, especially with the emergence of microprocessors and the increasing automation of industrial production, it has become an essential device in various process controls.
