Description

Technical Field

[0001] The present invention relates to an installation structure of a vehicle carrier, and particularly to an installation structure of an inertial navigation system on a vehicle carrier on an integrated controller. Background Art

[0002] Several common modern navigation technologies include celestial navigation, inertial navigation, satellite navigation, radio navigation, etc. Among them, only inertial navigation is autonomous, neither radiating anything to the outside nor looking at the stars in the sky or receiving external signals, and its concealment is the best.

[0003] An inertial navigation system (INS, Inertial Navigation System), also known as an inertial reference system, belongs to a deduced navigation method using inertial technology, that is, the position of the next point is deduced from the position of a known point based on the continuously measured course angle and speed of the moving body, so that the current position of the moving body can be continuously measured. The gyroscope in the inertial navigation system is used to form a navigation coordinate system, stabilize the measurement axis of the accelerometer in this coordinate system, and give the course and attitude angle; the accelerometer is used to measure the acceleration of the moving body, obtain the speed through the first integral with respect to time, and the displacement can be obtained by integrating the speed with respect to time again. The inertial navigation system is an autonomous navigation system that does not rely on external information and does not radiate energy to the outside (such as radio navigation). Its working environment includes not only the air and the ground, but also underwater. The basic working principle of inertial navigation is based on Newton's laws of motion. By measuring the acceleration of the carrier in the inertial reference system, integrating it with respect to time, and transforming it into the navigation coordinate system, information such as the speed, yaw angle, and position in the navigation coordinate system can be obtained.

[0004] The vehicle carrier computer has the characteristics of small volume, light weight, low power consumption, high reliability, strong real-time performance, and resistance to harsh environments. It is used as an integrated controller for the guidance and control of the vehicle carrier, pre-takeoff test and aiming calculation, in-flight real-time test calculation, and radio communication management, etc. Generally in the missile control system, it performs real-time processing according to the requirements of control functions and sends the processing results to the execution part of the control system. For example, when used for inertial guidance, the vehicle carrier computer receives the parameter values from the inertial devices, calculates the corresponding control instructions according to the requirements of the inertial guidance function, and controls the attitude of the vehicle carrier through the execution components to change the flight trajectory of the vehicle carrier to reach the target. Another example is the multi-computer system used in the vehicle carrier image matching guidance system, which consists of the relevant processor in the position correction system and the guidance computer in the inertial guidance system. The relevant computer performs image matching processing on the map image obtained by the radar and the pre-stored reference map to determine the instantaneous position of the vehicle carrier; the guidance computer corrects the tool error of inertial guidance using the instantaneous position data of the vehicle carrier to improve the guidance accuracy.

[0005] With the improvement of the performance indicators of the carrier and the increasingly strict requirements of the operating environment, the carrier computer will have better real-time performance, reliability, anti-radiation and reconfigurable capabilities, and will develop towards the direction of multi-function and intelligence.

[0006] The inventor found that it is necessary to solve the problem of firmly and reliably installing the inertial navigation system on the carrier computer as an integrated controller and being convenient to remove when debugging is required. Summary of the Invention
