Abstract

Interconnecting wires is sometimes difficult, inconvenient and even impossible when the light source controller is installed in the industrial field. In order to solve the problem above, a digital wireless LED light source controller for machine vision is proposed in this paper. Firstly, the hardware modules, including host computer software, embedded control unit program, power supply module, embedded control unit, display module, light source driving circuit, wireless serial communication module, infrared remote controller and infrared receiver, are described in detail to build the hardware platform. Secondly, the host computer software and its interface are introduced in detail, which are used to transmit the control instructions from the host computer. Finally, the control instructions are analyzed by the embedded control unit program, and according to the results of analysis, the embedded control unit adjusts the duty cycle of the PWM wave, so as to adjust the brightness of LED light source. This kind of light source controller with small heat productivity and reasonable structure can accurately and stably control the four channels of LED light source modules at the same time. And it inputs control instructions by no-contact way, which is useful in cases where interconnecting wires is difficult, inconvenient and even impossible and makes it easier to be used in the actual installation process. The digital wireless LED light source controller for machine vision is mainly applied into the industrial field on machine vision system.
