【摘要】：隨著物聯(lián)網(wǎng)、工業(yè)4.0概念的廣泛應(yīng)用和研究,以及近年來FPGA/CPLD等可編程處理器技術(shù)的快速發(fā)展,傳感器數(shù)據(jù)的采集已經(jīng)成為人們研究的焦點(diǎn)。由于各個應(yīng)用領(lǐng)域的功能需求復(fù)雜多樣,要求的研制的周期也越來越短,對于系統(tǒng)的自適應(yīng)性和實(shí)時性的要求也越來越高。因此,一個可重構(gòu)、通用性強(qiáng)、性能穩(wěn)定的數(shù)據(jù)采集接口設(shè)備對于各個領(lǐng)域的智能化系統(tǒng)都具有重要的意義。本課題首先深入研究了數(shù)據(jù)采集技術(shù)和可重構(gòu)技術(shù),總結(jié)目前這兩種技術(shù)的設(shè)計理論、方法及流程,并結(jié)合現(xiàn)在智能化技術(shù)的發(fā)展趨勢,建立本課題所研究的基于FPGA可重構(gòu)的數(shù)據(jù)采集接口技術(shù)的標(biāo)準(zhǔn)模式。然后,以Virtex4系列FPGA芯片為核心控制器設(shè)計了本課題的硬件板卡。硬件板卡包括基本模塊電路、MT8816開關(guān)矩陣模塊電路、SystemACE CF模塊電路。其次,用VHDL語言分別完成了傳感器數(shù)據(jù)采集系統(tǒng)所用芯片、傳感器、通信端口的驅(qū)動程序;并通過開關(guān)矩陣實(shí)現(xiàn)靜態(tài)重構(gòu)、通過SystemACE CF實(shí)現(xiàn)全局動態(tài)重構(gòu)、根據(jù)EAPR設(shè)計方法完成本課題局部動態(tài)可重構(gòu)的基本設(shè)計。最后,通過本設(shè)計在聚羧酸減水劑自動化生產(chǎn)中的實(shí)例應(yīng)用,驗(yàn)證了本設(shè)計在生產(chǎn)應(yīng)用中利用開關(guān)矩陣的任意橋接功能,實(shí)現(xiàn)接入到硬件板卡的各種類型傳感器的靈活切換;在生產(chǎn)過程中利用動態(tài)重構(gòu)技術(shù),可以動態(tài)實(shí)時的配置系統(tǒng)功能,配置靈活方便、且提高了硬件資源利用率。本課題實(shí)現(xiàn)了FPGA芯片、傳感器數(shù)據(jù)采集技術(shù)與可重構(gòu)技術(shù)的結(jié)合。與普通的數(shù)據(jù)采集設(shè)備相比,本設(shè)計提高了數(shù)據(jù)采集處理的速率,不僅可以靜態(tài)重配置系統(tǒng)功能,還可以在線實(shí)時重配置系統(tǒng)功能。本設(shè)計為工業(yè)自動化領(lǐng)域的傳感器數(shù)據(jù)采集工作做出了新的嘗試,也為下一代傳感器數(shù)據(jù)采集技術(shù)的發(fā)展提供了可參考的新模型。
[Abstract]:With the Internet of things, industrial 4.0 concept is widely used and research, and in recent years, FPGA/CPLD and other programmable processor technology rapid development. The collection of sensor data has become the focus of research. Because of the complex and diverse functional requirements in various application fields, the period of research and development required is also getting shorter and shorter. The requirement of self-adaptability and real-time of the system is higher and higher. Therefore, a reconfigurable and versatile. The data acquisition interface equipment with stable performance is of great significance to the intelligent system in all fields. Firstly, the data acquisition technology and the reconfigurable technology are studied in depth. This paper summarizes the design theory, method and flow of these two technologies, and combines the development trend of intelligent technology. Establish the standard mode of data acquisition interface technology based on FPGA reconfigurable. Then. The hardware card of this subject is designed with Virtex4 series FPGA chip as the core controller. The hardware card includes the basic module circuit and the switch matrix module circuit of MT8816. SystemACE CF module circuit. Secondly, the driver of the chip, sensor and communication port of the sensor data acquisition system is completed by VHDL language. And through the switch matrix to achieve static reconfiguration, through SystemACE CF to achieve global dynamic reconstruction, according to the EAPR design method to complete the basic design of the subject of local dynamic reconfigurable. Finally. Through the application of this design in the automatic production of polycarboxylic acid superplasticizer, it is verified that the design uses any bridging function of switch matrix in production application. Realize the flexible switch of various types of sensors connected to the hardware board; In the process of production, dynamic reconfiguration technology can be used to dynamically and real-time configure system functions, configuration is flexible and convenient, and improve the utilization of hardware resources. In this paper, a FPGA chip is implemented. The combination of sensor data acquisition technology and reconfigurable technology. Compared with the common data acquisition equipment, the design improves the speed of data acquisition and processing, not only can static reconfigure the system functions. It can also reconfigure the functions of the system in real time. This design has made a new attempt for the sensor data acquisition in the field of industrial automation. It also provides a new model for the development of the next generation sensor data acquisition technology.
