Device and method for program updating of rotary platform control system

Abstract

The invention discloses a device and method for program updating of a rotary platform control system and solves the problem of disassembly of a platform body in rotary platform control program updating. The method includes: sending a handshake command repeatedly, and determining whether to update a program or not according to answering conditions; by an upper computer, sending a file length, thensending an HEX file and storing in a RAM (random access memory), and finally performing program writing according to data and a Flash address obtained by HEX file analysis; in a communication process,guaranteeing safety and reliability of writing contents by fault detection and protection; adopting a mode of simultaneous storage of a standby program and an execution program to guarantee normal operation of a rotary platform in damage of the execution program. By adoption of the method, program updating can be directly performed through an external interface of the rotary platform, fault detection and program backup functions are achieved, and accordingly damages of the rotary platform due to running of damaged programs can be avoided. In addition, the device and the method for program updating of the rotary platform control system have advantages of simplicity and convenience in operation, safety, reliability and convenience in use for large-scale production.

Description

technical field [0001] The invention relates to a method and a device for upgrading a turntable control system program, belonging to the technical field of computer embedded systems. Background technique [0002] Turntable, also known as inertial navigation test equipment, can accurately simulate the motion environment of inertial devices and systems when they work, so as to provide accurate and detailed data reference for the development, production and maintenance of inertial devices and systems. As the core component of the turntable, the turntable control system is an embedded system. However, compared with the usual embedded system, the turntable control system has certain particularities: the turntable control system is placed in the table body, and the internal space is limited, and the disassembly process is more complicated; A lot of interference; the turntable is a non-standard equipment, and there are various types of external communication interfaces; the start-...

AI Technical Summary

Problems solved by technology

[0004] The present invention is aimed at the deficiencies in the above prior art and provides a method and device for program upgrading of the turntable control system. The method and device with rich interface types solves the problems in the program upgrade process of the traditional turntable control system that the table body needs to be disassembled, the faults in the upgrade process cannot be fully identified, the external communication interface cannot be matched, and the execution program startup time cannot be restricted.
