Description
Technical field
The utility model relates to microelectromechanical-systems technical field, is specially a kind of microelectromechanical-systems attemperating unit.
Background technology
Current MEMS gyro instrument and accelerometer are by process technology limit, export at different temperature and have larger parameter drift, under current existing processing scheme is mainly placed in sensor the artificial environment of slowly change, the parameter output that record different temperature points is corresponding, obtain the temperature compensation curve of this device, then on software, corresponding compensation is done, such scheme needs the longer time to obtain temperature compensation curve, and due to the characteristic of MEMS element, once sensor is subject to minor impact, temperature compensation curve also needs respective change, and user normally not to have corresponding equipment and condition again do temperature compensation in a production environment, which results in after microelectromechanical-systems uses a period of time, penalty, precision reduces.
Utility model content
The purpose of this utility model is to provide a kind of microelectromechanical-systems attemperating unit, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of microelectromechanical-systems attemperating unit, comprise printed circuit board (PCB) and micromotor GYROCHIP, and the top of printed circuit board (PCB) is provided with micromotor GYROCHIP, the surrounding of described micromotor GYROCHIP is equipped with baffle plate, and the bottom side of baffle plate is connected with printed circuit board (PCB), the inner side outer wall of described baffle plate is equipped with resistance, and the other end of resistance is connected with micromotor GYROCHIP, described baffle plate is flexibly connected with lid by cylinder axis, the rear side of described baffle plate is provided with temperature sensor and controller, and the right side of temperature sensor is provided with controller, described printed circuit board (PCB), micromotor GYROCHIP, temperature sensor, controller and resistance are electrically connected successively.
