Embodiment Construction

[0016] The present invention uses a DSP digital signal processor (such as TMS320C6416) as the main processing unit, and an external synchronous serial port chip to complete communication with the main control system; the FLASH memory chip stores updated target template images and application program data. There are three parts stored in the FLASH memory chip, which are the kernel program, application program and target template image data. The kernel program is a program that cannot be updated online, including communication with the main control system, data cache, erasing and reading and writing FLASH, program Jump and other functional modules; the application program captures the tracking algorithm program for the target, that is, the program data that needs to be updated online. The purpose of the present invention is to receive commands from the main control system (that is, the main control computer) at any time when the image processing board is in the non-capturing and ...

Abstract

The invention relates to a data real-time uploading and updating device. The device comprises an image processing board card, a synchronous serial port chip and a FLASH storage chip. A kernel programstored in the FLASH storage chip comprises a communication processing module used for completing data communication transmission and data analysis between the main control system and the image processing board card through a synchronous serial port chip. The data caching module is used for caching the received uploaded data. The FLASH erasing read-write module is used for carrying out erasing read-write operation on the FLASH storage chip. The program skipping module is used for realizing skipping from an application program to a kernel program or from the kernel program to the application program according to a command of the main control system. According to the device, the uploaded data can be received at any moment in a non-capture tracking state, data updating is completed, the systemdoes not need to be restarted after updating. Meanwhile, the influence of random power failure of the system in the data uploading process is avoided, and the system can still work normally after being powered on.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a device for uploading and updating data in real time. Background technique [0002] In the process of image guidance, it mainly automatically recognizes and tracks pre-designated strike targets by matching template images and real-time images. In the pre-war preparation stage, it is necessary to upload the pre-strike target template image to the FLASH memory chip of the image processing board in a short period of time. If the corresponding target capture and tracking algorithm, that is, the application program, is also changed, it needs to be completed together with the target template image Online real-time updates. In the test experiment stage, the image processing board can be connected through the emulator, and the FLASH data can be updated manually. In the actual application stage, the image processing board has been packaged, and the real-time upload and update ...
