Floater running-in device of three-floating inertial instrument

Abstract

The invention, which belongs to the technical field of inertial instruments, relates to a floater running-in device of a three-floating inertial instrument. The floater running-in device comprises a athree-floating inertial instrument floater (a to-be-tested test piece), a multi-channel motor power supply, a multi-channel electric signal monitoring module, a multi-channel temperature collecting module, a program-controlled temperature box and a host computer. And a plurality of three-floating inertial instrument floaters can be driven simultaneously to carry out running-in screening. According to the floater running-in device, the manual operation is replaced by the automatic control operation so as to realize timing automatic starting and stopping of running in and automatic collection and recording of data of the running-in process, so that the operator is freed from the monotonous and boring data recording work. Besides, the real-time monitoring and automatic processing functions for the running-in abnormity are introduced into the floater running-in device, so that the reliability of the running-in equipment is improved. When the running-in abnormity occurs, response to the abnormity is made timely and automatic grading processing is performed; and the float or equipment is protected from being damaged by the running-in abnormity.

Description

technical field [0001] The invention relates to a three-float inertial instrument float running-in device, a three-float inertial instrument float running-in device capable of timing automatic start and stop running-in, real-time collection and recording of running-in process data, real-time monitoring and automatic processing of running-in abnormalities The utility model relates to a closing device, which is used for the running-in screening of the floats of the three-float inertial instrument, and belongs to the technical field of the inertial instrument. Background technique [0002] The three-float gyroscope and the three-float gyro accelerometer (collectively referred to as the three-float inertial instrument) are designed using the fixed axis and precession of the high-speed rotating rigid body (gyro motor) respectively. The gyro motors of the two types of three-float inertial instruments are dynamic pressure air-floating hysteresis motors, which are sealed in the iner...

Problems solved by technology

Compared with traditional running-in equipment, this monitoring system frees the operator from the boring and cumbersome data recording process to a certain extent; however, this monitoring system realizes automatic data collection on the basis of traditional motor running-in equipment function, does not have the ability to interact with the running-in equipment, does not form a closed-loop control of the running-in process, cannot automatically and timely handle the abnormal situations that occur during the running-in process, and cannot avoid the possible damage to the float or equipment caused by the running-in abnormality damage; in addition, the device still relies on the operator to manually power on, power off and switch the running-in voltage of the float, etc.

[0005] To sum up, the traditional run-in equipment has a low degree of automation, a high degree of dependence on the operator, and a serious waste of manpower. Moreover, it does not have the function of monitoring abnormalities in running-in, and cannot automatically handle abnormalities in time. RISK OF INJURY FROM EQUIPMENT OR FLOAT
