摘要
为了解决LCD在黑暗环境下无法显示的问题,设计并开发了无源二线制智能数字显示表。该无源二线制智能数字显示表采用TI公司生产的MSP430FE427单片机进行控制,详细介绍了其工作原理和实现技术。该仪表能够在没有表头以及外接直流电源的情况下,通过显示模块对二线制传感器检测到的工业参数进行显示;具有精度高、配置灵活、稳定性好等特点,适合用作工业现场的显示单元。
In order to solve the problem of LCD, i. e. , it is impossible to display under dark environment, the two-wire passive intelligent digital indicator has been developed. The single chip computer MSP430FEA-27 from TI is used in the passive intelligent digital display for controlling. The operational principle and implementing technologies are introduced in detail. The instrument displays the industrial parameters detected by two-wire sensors without external DC power supply, and features high accuracy, flexible configuration and good stability. It is suitable for displaying unit in industrial fields.
