Embodiment Construction

[0018] Below in conjunction with accompanying drawing and specific example the present invention will be further described;

[0019] figure 1 Shown is the front panel interface of LabVIEW in the server to adjust the brightness of the lighting equipment. The lighting brightness is divided into different levels to simulate the adjustment knob of the light source controller. The light source controller used in the present invention is OPT-DPA1024E-4 OPT light source controller, based on RS232 serial port and computer communication, using COM1 communication port for data transmission, all communication bytes use hexadecimal code, data format It is 1-byte feature word, 1-byte command word, 1-byte channel word, 2-byte data word and 1-byte check word.

[0020] According to the DLL (Dynamic Link Library) file provided by Opto, multiple subroutines such as communication port selection Vi, delay time Vi, string Vi, brightness level Vi, etc. are generated in LabVIEW, and LabVIEW and lig...

Abstract

The invention provides a LabSocket-based method for remote adjusting of illumination intensity. The method comprises the following steps: a light source controller communicates with a computer through an RS232 serial port and uses a COM1 communication port to transmit the data; in LabVIEW, a subroutine including communication port selection and brightness level selection is generated; by means of calling the subroutine, direct adjusting of light intensity by the LabVIEW is realized; an NI remote control toolkit LabSocket is installed on the computer as a server; a virtual machine is installed on the server to obtain a computer IP address; in the virtual machine environment, a LabSocket System is used to open a program chart of the LabVIEW to control light intensity; a remote control starting end is established; an IP address is input into an IP address box of the remote control starting end; and the remote control of the lighting intensity is realized through adjusting a rotary button at a client terminal to compensate for the ambient light according to the intensity of the ambient light to realize the remote control of the lighting intensity.

Description

technical field [0001] The invention relates to a method for remotely adjusting light intensity based on LabSocket, which belongs to the field of remote control. Background technique [0002] Machine vision is to use machines instead of human eyes for measurement and judgment. In the process of mass repetitive industrial production, it can greatly improve the efficiency and automation of production. A typical machine vision includes image capture, light source system, image digitization module, digital image processing module, intelligent judgment decision-making module and mechanical control execution module. The reliability of judgment decisions depends on the quality of the acquired images, and the quality of the images depends on the image acquisition system and the intensity of the light source. [0003] In addition to the light source system of machine vision, the light intensity also includes external ambient light. External ambient light is random and uncertain. Fo...
