Universal computer based on dual-ARM (advanced RISC machine) singlechip for platform-type inertial navigation equipment

Abstract

The invention discloses a universal computer based on a dual-ARM (advanced RISC machine) singlechip for platform-type inertial navigation equipment. The universal computer comprises an AD (analog-digital) collecting board and a computer baseplate, wherein the AD collecting board and the computer baseplate are respectively provided with a first ARM processor and a second ARM processor, and are separated, the data processing speed is improved, meanwhile, problems can be conveniently found out, and the universal computer is convenient to replace and maintain; an industrial-level ARM chip is selected to operate under the environment of -40 to 80 DEG C; functions integrated in the ARM singlechip are rich, and the required peripheral circuit is simple, so that the navigation computer formed by the ARM chip is simple in circuit, small in volume, low in cost, and is high in reliability, and the capability for adapting to the severe environment is strengthened greatly; and meanwhile, the universal computer can adapt to single-axis, dual-axis or three-axis inertial navigation equipment only by changing the software, thus having good universality.

Description

technical field [0001] The invention relates to an inertial navigation computer system, in particular to a platform-type inertial navigation equipment general-purpose computer based on dual ARM single-chip microcomputers for the platform-type inertial navigation system. Background technique [0002] The existing platform navigation system is mainly implemented in the form of an upper-lower computer composed of a PC104 computer and a single-chip microcomputer. The single-chip microcomputer completes the data acquisition task, and sends the data to PC104 through the serial port, parallel port or PC104 bus, etc., and the PC104 calculates the compensation amount according to the data collected by the lower computer according to the navigation error compensation model, and realizes the compensation through D / A. [0003] The platform navigation system based on PC104 computer has large volume, high power consumption, high cost, poor environmental adaptability, especially low temper...

Problems solved by technology

[0005] Other single-chip microcomputers such as 8051, AVR and other systems have insufficient computing power, and cannot well realize the dual tasks of multi-sensor data acquisition and navigation calculation. There are few peripherals, and it is not convenient to use an embedded real-time operating system, which is difficult to meet real-time requirements.
