Embodiment

[0026] Example: see Figure 1 to Figure 5 , the present embodiment provides a multifunctional control method for a machine vision light source, which includes the following steps:

[0027] (1) A central control unit, a power supply module, a display trigger module, an I / O module, an analog-to-digital conversion module and a USB communication module electrically connected to the central control unit are set;

[0028] (2) A control chip is provided in the central control unit, and a current output control module and a digital I / O control module are embedded in the control chip;

[0029] (3) The current output control module includes a trigger control mode and a program control mode;

[0030] (4) When the trigger control mode is selected, it has two trigger modes: high-level trigger and low-level trigger. Through the input terminal connected to the I / O module, the output parameters of multiple output channels can be manually set one by one. The output parameters include the dur...

Abstract

The invention discloses a machine vision light source multifunctional control method which is characterized by including the following steps: when a trigger control mode is selected, a high-level trigger mode and a low-level trigger mode are available, the output parameters (including the duration of output level and the magnitude of output current) of multiple output channels are manually set one by one through an input end connected with I / O modules, and after setting, a trigger operation is performed to realize trigger control; and when a program control mode is selected, a central control unit outputs 38KHz square wave cycle pulse to the output port, and controls the pulse width of the output channel of each I / O module by pre-inputting the value of the duty ratio of high level, so as to realize program control. The invention further discloses a machine vision light source multifunctional controller for implementing the method.

Description

technical field [0001] The invention relates to the field of machine vision detection, in particular to a multifunctional control method for a machine vision light source and a multifunctional controller for a machine vision light source implementing the method. Background technique [0002] Existing machine vision light source controllers include analog controllers, digital controllers, strobe controllers, etc., but these controllers can only complete one control, and cannot realize simultaneous control of multiple control signals. Larger, but when input and output are required, an additional I / O connection device needs to be connected to implement external input and output, which is extremely inconvenient to use. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art, provide a multifunctional control method for machine vision light sources, and a multifunctional controller for machine vision light sources ...
