数字称重系统总线接口防雷保护的方法

Methods of mine protection for bus interface of digital weighing system

数字汽车衡防雷一直是传感器生产厂家和仪表生产厂家设计的重点,本文从雷击特点分析出发,结合数字传感器和仪表总线接口特点,阐述防雷原理和措施,最后以数字传感器为例给出接口防雷保护电路建议。

Digital vehicle lightning protection has always been the focus of the design of sensor manufacturers and instrument manufacturers. This paper starts from the analysis of the characteristics of lightning strikes and combines the characteristics of digital sensors and instrument bus interfaces to explain the lightning protection principles and measures. Finally, a digital sensor is used as an example to give the suggestion of the interface lightning protection circuit.
