Embodiment Construction
[0040] The present invention will be described in detail below with reference to the drawings and embodiments.
[0041] "The sensor is a pre-component in the measurement system, which converts the input variable into a signal for measurement." Such as figure 1 Shown is the block diagram of the sensor system.
[0042] 1. Technical scheme for downtilt angle measurement
[0043] (1) Principle of acceleration sensor
[0044] The most basic principle of an acceleration sensor is that a certain medium is deformed due to acceleration, and the deformation is measured and converted into a voltage output by a related circuit. This voltage represents the magnitude of acceleration.
[0045] The sensor is mainly composed of a polysilicon mechanism using surface micromachining and a differential capacitor. The polysilicon structure is supported by a polysilicon spring, is located on the top of the wafer, and is connected to the motion center plate of the differential capacitor. Two square waves wi...
