Embodiment Construction

[0051] Such as figure 1 As shown, the high-speed image data storage device based on the LVDS interface of the present invention includes a data acquisition receiving module, a switching value receiving module, a storage module, a main control module (FPGA), an Ethernet communication module and a power supply module.

[0052] The data acquisition and receiving module uses the deserializer to convert the serial LVDS image data into 16-bit parallel data. After the deserializer is locked, the parallel data is sent to the main control module. The data acquisition and receiving module includes three identical deserialization channels. The device can capture three images at the same time.

[0053] The switching value receiving module uses an optocoupler to receive the switching value, and then sends it to the main control module after isolation. The switching value is input from the outside. When the main control module scans the switching value, anti-shake operation is required. Wh...

Abstract

The invention relates to a high-speed image data storage device based on LVDS interfaces. The device comprises a data collection and receiving module, a switching-value receiving module, a storage module, a main control module, an ethernet communication module and a power supply module. The device can simultaneously record 3-way LVDS images, a system selects and uses six flash chips, storage capacity of each flash chip is 4GB, and thus total storage capacity of the system is 24GB. The device has a two-way independence storage function, and can erase or extract data according to an external instruction. Dual-plane two-stage flow-line programming thinking is adopted, FIFO ping-pong operation is utilized, and image source data with a maximum transmission speed of 35.6MB/s can be recorded.
