Abstract

The invention discloses a pulse detection sensor based on linear driving. The pulse detection sensor based on linear driving is mainly composed of a sensor body, a main control chip K, a rectifying circuit connected with the main control chip K, and a pulse detection circuit connected with the sensor body. The pulse detection sensor based on linear driving is characterized in that a linear driving circuit is arranged between the pulse detection circuit and the rectifying circuit and is composed of a driving chip U, a triode VT3, a triode VT4, a triode VT5, a triode VT6, a polar capacitor C6, a resistor R10 and the like, the positive electrode of the polar capacitor C6 is connected with the pulse detection circuit, the negative electrode of the polar capacitor C6 passes through a resistor R9 and then is connected with an IN1 pin of the driving chip U, one end of the resistor R10 is connected with the collector electrode of the triode VT6, and the other end of the resistor R10 passes through a resistor R11 and then is connected with the base electrode of the triode VT3. According to the pulse detection sensor based on linear driving, due to the fact that the linear driving circuit is arranged, it can be guaranteed that the sensor is prevented from being disturbed when used for detecting pulse error signals.

Description

technical field [0001] The invention relates to an electronic sensor, in particular to a pulse detection sensor system based on loss suppression. Background technique [0002] In order to obtain information from the outside world, people must rely on sensory organs. However, relying on people's own sensory organs alone is far from enough for their functions in the study of natural phenomena and laws and production activities. To accommodate this situation, sensors are needed. Therefore, it can be said that the sensor is an extension of human facial features, also known as electrical facial features. [0003] With the advent of the new technological revolution, the world has entered the information age. In the process of using information, the first thing to solve is to obtain accurate and reliable information, and sensors are the main ways and means to obtain information in the natural and production fields. In modern industrial production, especially in the automated pr...
