伴随社会不断的发展和进步,自动化程度越来越高,传感器应用的场合也逐渐增多,然而传感器的实际工作的环境一般都是比较恶劣的,由于其输出的电信号幅值很小,而且和电路连接之间存在一段距离,这样电缆电阻、传感器内阻、放大电路及周围环境产生的噪声均对放大电路存在干扰,影响传感器的正常工作,因而必须必须制定对策解决传感器应用中的各种干扰问题。本文就是分析了常见的干扰类型和入侵系统的途径方面入手,提出了针对性的对策,以提高系统工作的稳定性和准确性。
With the constant development and progress of the society, the degree of automation is getting higher and higher, and the applications of the sensors are gradually increasing. However, the actual working environment of the sensors is generally harsh due to the small amplitude of the output electrical signals and There is a distance between the circuit connections, so that the cable resistance, the sensor resistance, the amplifier circuit and the noise generated by the surrounding environment are interfering with the amplifier circuit, affecting the normal operation of the sensor, which must be developed to address various interference sensor applications problem. This article is to analyze the common types of interference and ways to invade the system, put forward targeted measures to improve the stability and accuracy of the system.
