An online software programming device and method

Abstract

The invention relates to a device and method for online software programming. The device comprises rocket control equipment, comprehensive testing and control equipment and ground testing equipment, wherein the comprehensive testing and control equipment comprises a board card and a coupler; the coupler is connected to the ground testing equipment by a bus and a fifth connector, the bus is divided by the coupler into two bundles, one bundle is connected to a communication interface of the rocket control equipment by a first connector, and the other bundle is connected to the board card; and the device also comprises a second connector which is connected to a programmable port of the rocket control equipment as well as a third connector and a fourth connector successively connected to the second connector. The device provided by the invention has the advantages that the structure is simple; operations are easily; manufacture cost is low; and the device has very high universality between different systems. The method provided by the invention has the advantages that remote embedded programs can be updated and downloaded; system upgrade cost can be reduced; research processes can be optimized; and the method can be widely applied in various remote embedded program update fields and has extensive reference significance.

Description

technical field [0001] The invention relates to the field of embedded systems, in particular to an online software programming device and method. Background technique [0002] With the in-depth development of my country's manned spaceflight projects, higher requirements have been put forward for the accuracy of launch vehicles, especially in recent years, the introduction of control system redundancy technology and iterative guidance methods has greatly increased the amount of launch vehicle flight control data. Increase. [0003] At present, most rockets use flight control software pre-stored in the computer on the rocket. Although this storage method can easily update the control software in the computer on the rocket before the rocket is assembled, once the computer on the rocket is loaded into the rocket and docking is completed, the traditional method cannot be used to update the computer on the rocket. The control software is updated. [0004] Therefore, how to provi...
