【摘要】：為滿足深海資源的探測(cè)開發(fā)中傾斜角度精確測(cè)量的要求,設(shè)計(jì)一種高精度的傾角測(cè)量系統(tǒng)。系統(tǒng)包括以內(nèi)置高精度溫度傳感器的加速度計(jì)MS9001.D和微處理器STM32為核心的硬件電路,以24bit A/D轉(zhuǎn)換器ADS1251U采樣、算法溫度補(bǔ)償和全雙工異步通信為核心的下位機(jī)軟件以及以NI為核心的Lab VIEW上位機(jī)軟件。實(shí)現(xiàn)基于MODBUS協(xié)議的RS485接口連接上位機(jī),實(shí)時(shí)顯示并將采集到的角度值按照系統(tǒng)時(shí)間存儲(chǔ)于上位機(jī)。編寫IIR數(shù)字濾波算法,充分抑制振動(dòng)噪聲干擾。實(shí)測(cè)結(jié)果表明:該系統(tǒng)傾角測(cè)量精度可達(dá)0.01°,輸出響應(yīng)頻率為2 Hz,具備環(huán)境溫度補(bǔ)償功能,滿足實(shí)際深海作業(yè)需求。
[Abstract]:In order to meet the requirements of accurate measurement of tilt angle in the exploration and development of deep-sea resources, a high-precision inclination angle measurement system is designed. The system includes hardware circuits with MS9001.D and STM32 as the core of accelerometer with built-in high-precision temperature sensor. Based on 24bit A / D converter ADS1251U sampling, algorithm temperature compensation and full-duplex asynchronous communication, the lower computer software and Lab VIEW PC software with NI as the core, the RS485 interface based on MODBUS protocol is realized to connect the host computer. Display the angle value in real time and store the angle value in the upper computer according to the system time. Write the IIR digital filter algorithm, The measured results show that the precision of the system can reach 0.01 擄and the output response frequency is 2 Hz. The system has the function of environmental temperature compensation and meets the practical requirements of deep-sea operation.
