【摘要】：海洋基本要素測量是國家海洋戰(zhàn)略的重要組成部分。隨著對深海信息探尋的不斷深入,常規(guī)的海流測量裝置很難滿足深海探測的需求,所以開發(fā)一款高精度、性能穩(wěn)定的深海海流傳感器迫在眉睫。課題組以國家自然科學(xué)基金項(xiàng)目“可測上升流的三維瞬時(shí)海流傳感器研究”(NO.41076061)為依托,設(shè)計(jì)了一款新型的深海海流傳感器。為了標(biāo)定傳感器的性能指標(biāo),本文研制了一套模擬海流運(yùn)動(dòng)的海流傳感器標(biāo)定平臺,通過絕對標(biāo)定的方法對新型深海海流傳感器進(jìn)行標(biāo)定。 對海流傳感器標(biāo)定平臺的性能進(jìn)行分析,提出標(biāo)定平臺的設(shè)計(jì)要求,確定海流傳感器標(biāo)定平臺的軟硬件運(yùn)動(dòng)控制方案。選用FPGA作為核心處理器進(jìn)行控制系統(tǒng)設(shè)計(jì)。首先,在核心處理器的基礎(chǔ)上規(guī)劃硬件控制板,實(shí)現(xiàn)核心板與擴(kuò)展板分離,提高運(yùn)動(dòng)控制器的可移植性。主要包括串口通信、位置檢測、電源電路、模擬電壓輸出等模塊的設(shè)計(jì)；其次,在控制板的基礎(chǔ)上,運(yùn)用Verilog HDL語言對下位機(jī)各模塊進(jìn)行程序設(shè)計(jì),包括PID位置控制、光柵尺信號采集、D/A轉(zhuǎn)換器模擬量輸出、位置模式控制等算法的實(shí)現(xiàn),通過FPGA實(shí)現(xiàn)全閉環(huán)控制；最后,在LaBVIEW編程環(huán)境中,以下位機(jī)程序?yàn)榛A(chǔ),通過VISA驅(qū)動(dòng)實(shí)現(xiàn)上、下位機(jī)之間的串口通信,力求開發(fā)出入性化的上位機(jī)控制界面,用來實(shí)現(xiàn)海流傳感器標(biāo)定平臺的控制數(shù)據(jù)輸入以及光柵尺采集數(shù)據(jù)的顯示和存儲(chǔ)等功能。 在搭建好整個(gè)海流傳感器標(biāo)定平臺之后,分別在位置模式下和速度模式下對運(yùn)動(dòng)控制系統(tǒng)進(jìn)行相關(guān)試驗(yàn)驗(yàn)證,并對實(shí)驗(yàn)數(shù)據(jù)進(jìn)行分析,進(jìn)一步論證標(biāo)定平臺的可行性。通過總結(jié)當(dāng)前成果,提出未來工作的方向。
[Abstract]:The basic elements of marine surveying is an important part of the national marine strategy. With the exploration of deep information deeply, the current conventional measuring device is difficult to meet the requirements of deep-sea detection, so the development of a high precision, stable performance of the deep sea current sensor is imminent. The research group to research on 3D transient current sensor for measuring the upwelling state the natural science fund project "(NO.41076061) as the basis, designed a new type of deep sea current sensor. In order to calibrate the sensor performance index, this paper developed a simulation of the current current sensor calibration platform, the new type of deep ocean current sensor was calibrated by using the method of absolute calibration.
The current sensor calibration platform for performance analysis, design requirement of calibration platform, determine the hardware and software platform of the current motion sensor calibration control scheme. FPGA is selected as the core processor, the design of the control system. Firstly, the hardware control board based on planning core processor, realize the core board and extended plate separation, improve motion controller portability. Including serial communication, position detection, power circuit design, analog voltage output module; secondly, based on the control board, the use of Verilog HDL language program design of each module, including the PID position control, grating signal acquisition, D/A converter analog output, realize the position mode control algorithm, through the FPGA to achieve closed-loop control; finally, in the LaBVIEW programming environment, the computer program is based, driven by VISA The serial communication between the upper and lower computers tries to develop the access control interface, which is used to realize the control data input of the calibration platform of the ocean current sensor and the display and storage of the data collected by the grating ruler.
After building the whole current sensor calibration platform, were related to test and verify the motion control system in position mode and speed mode, and analyze the experimental data, further demonstrates the feasibility of the calibration platform. Through the summary of the current results, puts forward to the direction of work.
