Problems solved by technology

[0004] 1. The traditional inductive sensor, once assembled, all parameters of the product cannot be changed, and the inductive sensor itself is a high-precision signal measuring instrument. If there is a slight difference in assembly, the switch point of the sensor may shift, thus The product does not meet the technical standards, or even scrapped directly
[0005] 2. Traditional inductive sensors, after long-term power supply or storage, may also cause the switch point to shift, so that the product does not meet the technical requirements
[0006] 3. For traditional inductive sensors, there are many and complicated assembly and debugging steps on the production line, so there are certain technical skills required for employees
[0007] 4. The traditional inductive sensor has a single output signal and can only output high and low levels at a fixed switch point, which cannot realize the automation and intelligence of the current industrial control

Abstract

The invention relates to an intelligent induction type sensor, and belongs to the technical field of sensors. The intelligent induction type sensor comprises a power source circuit, a capacitance three-point type oscillating circuit, a single-chip microcomputer connected with the output of the capacitance three-point type oscillating circuit, an input circuit and an output circuit, wherein the input circuit and the output circuit are connected with the single-chip microcomputer and connected with an external control panel through a communication bus, the single-chip microcomputer is used for realizing switchover of a data transmission function and a logic output function, the input circuit is used for data transmission, switch on and off of the input circuit are controlled by signals sent by the external control panel, the output circuit is used for outputting logic signals, and switch on and off conditions of the output circuit are controlled by the single-chip microcomputer according to the switch on and off conditions of the input circuit and keep opposite to those of the input circuit. Through isolation of the data transmission function and logic output function, parameter modification of finished products is realized, and multiple functions are integrated.

Description

technical field [0001] The invention relates to a sensor, in particular to an intelligent inductive sensor. Background technique [0002] With the coming of the digital age and the rapid development of digital products, it is an inevitable trend to digitize the underlying equipment in order to control the underlying equipment conveniently, effectively and accurately in the control system. Sensors are the most basic elements to realize intelligent control and remote control. [0003] In the existing traditional inductive sensor, the signal collected by the oscillation module is filtered and converted into an analog voltage change, and then the analog voltage is compared with a fixed voltage to directly output a logic level. like figure 1 Shown is the power supply circuit of a traditional inductive sensor; figure 2 Shown is a typical capacitive three-point oscillator circuit used in traditional inductive sensors. The traditional inductive sensor has the following disadvan...
