A Design and Calibration Method of Underwater Digital Depth Sensor

摘要:

在水下设备的设计过程中，往往需要根据不同的水深执行相应的动作或参与不同的运算处理。 提出一种数字深度传感器的设计和微分式标定方法，采用新华龙 24 位高精度模数混合处理器作为信号处理单元，对压力应变片的模拟量进行采集标定和变送，最终输出结果为数字信号传输。详细介绍了该数字式深度传感器的设计原理和标定方法，通过与以往该类别传感器实验对比以及在实际使用中充分验证，体现了该传感器精度高和抗干扰能力强的特点，具有工程应用价值。

Abstract:

In the design process of underwater equipment，it is often necessary to perform corresponding actions or participate in different operations according to different depths. In this paper，a design and differential calibration method of digital depth sensor is proposed. Silicon Labs 24-bit high-precision analog digital mixed processor is used as the signal processing unit to collect，calibrate and transmit the analog quantity of pressure strain gauge，and the final output is transmitted as a digital signal. The design principle and calibration method of the digital depth sensor is introduced in detail in this paper. Compared with previous experiments of this kind of sensor， and fully verified in actual use，the sensor is characterized with high precision and strong anti-interference ability， and it has engineering application value.
