Problems solved by technology

[0003] At present, the data of the two inertial navigations in the vehicle test are collected separately by the computer. The disadvantages are: the collected data are two independent files, which must be analyzed offline after the test is over, and cannot be compared in real time; the two sets of data cannot be accurately aligned. axis; offline data analysis takes a lot of time

Embodiment Construction

[0018] The present invention will be described in further detail below. figure 1 It represents the architecture of the vehicle inertial navigation data acquisition system of the present invention. Such as figure 1 As shown, the vehicle-mounted inertial navigation data collection system of the present invention includes a data collector 1, a main inertial navigation 2, a sub-inertial navigation 3, a display computer 4, and a power supply 5. The data collector 1 is connected to the main inertial navigation system 2 through one RS232 / RS422 interface 8, and one RS232 / RS422 interface 9 is connected to the sub-inertial navigation system 3 to receive the data of the main and sub-inertial navigation systems respectively. The data collector 1 is then connected to the display computer 4 through an RS232 interface 10 for sending processed data. The data collector 1 is powered by a power supply 5 and has a USB interface 6 and a network interface 7 for exporting stored data.

Abstract

The invention belongs to the field of inertial navigation and relates to a vehicle-mounted inertial navigation data acquisition system. The system comprises a data collector 1, a main inertial navigator 2, a sub inertial navigator 3 and a display computer 4, wherein both the main inertial navigator 2 and the sub inertial navigator 3 transmit data to the data collector 1, and the data collector 1 analyzes the two paths of data, aligns with a time axis, calculates the data in real time to obtain the navigation error information of the sub inertial navigator 3 and the main inertial navigator 2, and outputs all the data to the display computer 4.

Description

technical field [0001] The invention belongs to the field of inertial navigation and relates to a vehicle-mounted inertial navigation data acquisition system. Background technique [0002] Inertial navigation is a core component of the missile, which is used to measure the current position, attitude, speed and other information of the missile, and its accuracy represents the performance of the inertial navigation. When a set of inertial navigation is performing dynamic performance verification tests, another set of high-precision inertial navigation is often required to provide a reference for navigation information for comparison. The former is called sub-inertial navigation, and the latter is called main inertial navigation. During the dynamic performance verification test, the main inertial navigation system and the sub-inertial navigation system will be installed in a special car, and the two will be fixedly connected on the same reference plane, and the navigation infor...
