Abstract

The invention discloses an intelligent digital display angle sensor. The angle sensor comprises a high sensitivity angle sensing chip, an embedded industrial microprocessor, a pulse width modulation and control module, a digital display and an infrared remote control. The intelligent digital display angle sensor is characterized in that the microprocessor is connected with the angle sensor, the pulse width modulation and control module and the digital display, and is in wireless communication connection with the infrared remote control. The microprocessor outputs signals in the form of pulse width modulation signals in real time, and outputs voltages of 0-10V, 0-5V and + / -5V, 4-20mA current, and serial digital communication respectively through an analogue voltage output port, a current output port and a serial communication port. The three types of output signals can be used as control source input signals for industrial control application; and the infrared remote control is used for controlling field application of the angle sensor in a non-contact way in real time. The angle sensor can be widely applied to multi-unit synchronous control in fields of textile, paper making, leather, cable and iron and steel.

Description

technical field [0001] The present invention relates to an intelligent digital display angle sensor, more specifically, relates to an intelligent angle sensor which can display the angle based on infrared intelligent control of an angle sensor chip and a microprocessor. Background technique [0002] In recent years, with the rapid development of sensing technology, the application requirements for angle sensors are increasing. However, most of the traditional angle sensors are Hall sensors and potentiometer angle sensors, which have defects such as low precision, large size, difficult installation, and difficult calibration and adjustment. [0003] In response to the defects of traditional sensors, sensors that rely on the magnitude of the acceleration component of the acceleration of gravity on the measurement axis to measure the angle value have also appeared on the market. However, its accuracy and angle setting parameters all depend on the acceleration sensor. To a lar...
