Optimized software online updating method capable of achieving non-missile-moving of missile-borne equipment

Abstract

The invention provides an optimized software online updating method capable of achieving non-missile-moving of missile-borne equipment. The method comprises the steps that a scheduling program is added between a Boot guiding program and an application program of the missile-borne equipment; after the missile-borne equipment is electrified and started, the scheduling program is loaded and executedby the Boot guiding program, and code matching procedures are executed by the scheduling program; if code matching is successful, application program updating procedures are executed; the packet datasent by the host computer is received, verification is conducted on the packet data in real time, and a single package program is taken out after the verification is correct and saved in an RAM; overall verification is conducted on the complete program data in the RAM, after the verification is correct, the program data is programming to FLASH, and read back is conducted for byte alignment.

Description

technical field [0001] The invention relates to the technical field of upgrade of missile-borne embedded software, in particular to an optimized online upgrade method for bomb-borne equipment non-disposal software. Background technique [0002] Traditional missile on-board equipment does not consider not to upgrade the bomb dismantling software online. In the later development process, it is frequently necessary to dismantle the missile, and return each product to the production unit for separate software upgrades, wasting a lot of cost. [0003] In the newly developed missiles, some models have realized the online upgrade function of the missile-borne equipment software, but this solution is implemented in the application layer software, and a complex A / B partition software upgrade, measurement, and guidance solution needs to be designed to solve the upgrade During the process, the application program is destroyed due to unexpected power failure or abnormal operation, and i...

[0002] Traditional missile on-board equipment does not consider not to upgrade the bomb dismantling software online. In the later development process, it is frequently necessary to disassemble the missile, and return each product to the production unit for software upgrade separately, wasting a lot of cost

[0003] In the newly developed missiles, some models have realized the online upgrade function of the missile-borne equipment software, but this solution is implemented in the application layer software, and a complex A / B partition software upgrade, measurement, and guidance solution needs to be designed to solve the upgrade During the process, the application program is destroyed due to unexpected power failure or abnormal operation, and it cannot be restarted or upgraded again, which increases the complexity of the software design of each device. In addition, this function is integrated in the application program, which may cause the application program to There are some unforeseen hidden dangers
