Embodiment Construction

[0025] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0026] exist figure 1 The middle PC is connected with the single-chip microcomputer module (MCU) through the RS232 serial port, and connected with the signal collector through the USB interface. The signal collector is connected with the sensor by falling. A single-chip microcomputer module (MCU), a stepping motor driver, and a stepping motor are connected in series through wires. The sensor unit is connected to the installation platform through four screws, and the installation position of the sensor can be adjusted by adjusting the gasket, so that the sensor is in the position required by the calibration method. The mou...

Abstract

The invention relates to an MEMS (micro-electromechanical system) angular speed and acceleration sensor automatic demarcating method and a system thereof. The system comprises a sensor mounting platform, a signal collector with a USB (universal serial bus) interface and an A / D (analog to digital) converting function, a steeping motor control module, a stepping motor execution control module, a sensor signal value collecting module and an automatic demarcating module, the stepping motor control module, the sensor signal value collecting and the automatic demarcating module execute on a PC (personal computer), the stepping motor execution control module executes on a single chip microcomputer, the stepping motor control module is further provided with a human-computer interface on the PC, the stepping motor control module and the stepping motor execution control module adopt the subdivision technology to subdivide rotating angle and rotating speed of a stepping motor rotary shaft. By adopting the MEMS angular speed and acceleration sensor automatic demarcating method and the system thereof, demarcating personnel is not needed to personally perform data processing for each demarcation to obtain demarcating results, so that workload is reduced for the demarcating personnel.

Description

technical field [0001] The invention relates to the field of sensor calibration, in particular to an automatic calibration method and system for MEMS angular velocity and acceleration sensors. Background technique [0002] With the promotion and development of MEMS technology, the application fields of angular velocity and acceleration sensors based on MEMS technology are becoming wider and wider. Since the performance of the sensor will be affected by the surrounding environment, the sensor must be recalibrated frequently to ensure its measurement accuracy. At present, there is no system platform that can automatically calibrate both the angular velocity sensor and the acceleration sensor, and each calibration requires the calibration personnel to process the data by themselves to obtain the calibration results, which increases the workload of the calibration personnel. Contents of the invention [0003] The technical problem to be solved by the present invention is to p...
