Problems solved by technology

Due to the damage of the data line, the data collected by the CCD cannot be transmitted to the PC for processing, resulting in calibration failure and normal exposure or interruption of the AOI detection system
[0005] On the client side, equipment failures caused by damage to the CCD data line occur from time to time; sometimes the equipment is down for several hours due to a problem with only one line, which brings huge economic losses to the customer and also brings great harm to the brand of the equipment supplier. big negative impact

Abstract

The invention discloses a method for solving a problem of transmission abnormity of image collection data in laser transmission, and the method comprises at least one image collection device CCD, network extension equipment, a mobile positioning platform for fixing the CCD, and a PC. The network IP addresses of the CCD and the PC are set as the same subnet segment. A PC end directly accesses to the corresponding CCD through the IP address of the CCD or the name of the CCD. A CCD data line and a mobile positioning platform can remain relative stationery in motion, thereby greatly reducing the probability of the data line, and enabling the CCD to transmit data to the PC end quickly and reliably. Meanwhile, the method employs an Ethernet interface, is good in expansibility and compatibility, and is better in transmission rate and reliability.

Description

technical field [0001] The invention relates to a data transmission method of an image acquisition system, in particular to a method for solving abnormal transmission of image acquisition data in laser transmission, and belongs to the technical field of VLSI equipment industry. Background technique [0002] CCD (Charge Coupled Device) image sensor is a high-performance solid-state imaging device, which converts optical signals into electrical signals, and is widely used in image acquisition systems and measurement detection systems. It has the advantages of wide spectral response, good linearity, wide dynamic range, low noise, high sensitivity, and real-time transmission, so it plays a very important role in scientific research, production testing, and national defense and military industries. [0003] Multiple CCDs are installed in the multi-optical laser direct imaging system and the high-speed AOI inspection system for system calibration and fast defect detection. Whethe...
