Embodiment Construction

[0023] The present invention will be further introduced below in conjunction with the accompanying drawings.

[0024] figure 1 It is a structural diagram of the hardware system. As shown in the figure, ten high-speed line-scan cameras 1 are divided into two groups and interconnected by cascading. . Two front-end industrial computers 2 can work at the same time. In order to ensure the synchronization of camera acquisition signals, when the two industrial computers work at the same time, one of the front-end industrial computers 2 is set as the main working mode in the working software, and the other industrial computer is working The software is set as slave working mode. The front-end industrial computer 2 processes the data collected by the camera through image processing software, records the changing status of all lights, and writes them into a file, saves a file every minute, and automatically sends the file to the server 3 for the user to record Query, data analysis an...

Abstract

A non-contact high-speed acquisition and recognition method based on a multi-line array camera. The specific steps are: 1) Install the auxiliary positioning bracket on the front panel of the device to be recognized, and compare the position of the diode on the circuit board with the indicator light on the device to be recognized. 2) Make each row of diodes on the circuit board fully bright, and adjust the position of each high-speed line-scan camera so that the high-speed line-scan camera can capture the corresponding row of diodes on the circuit board; 3) Remove The auxiliary positioning bracket completes the rough positioning, and the system starts to collect and identify. The method of the invention can meet the requirement of indicator light identification under the condition that the timing accuracy of indicator light changes is relatively high, and realize unattended high-precision record identification. Since the present invention adopts a non-contact design, it is not necessary to keep in contact with the device to be identified during use, and its properties will not be affected.

Description

technical field [0001] The invention belongs to the field of computer monitoring and relates to a non-contact high-speed acquisition and identification method based on a multi-line array camera. Background technique [0002] There are often many indicator lights on the equipment in the equipment control room, which are used to indicate the operating status of the corresponding equipment. Because there are many indicator lights on the equipment, and the speed of change is fast, it is easy to generate erroneous data when the personnel on duty record, especially some important indicator lights. Once the state changes of the indicator lights are misjudged or missed, serious s consequence. This requires the intervention of computer monitoring technology. [0003] Computer monitoring technology is a challenging and important research field in the scientific field, and high-speed image acquisition technology is a special requirement in computer monitoring technology. In high-spe...
