【摘要】：隨著科技的不斷進(jìn)步,國防、天文、工業(yè)、農(nóng)業(yè)等領(lǐng)域經(jīng)常需要對電壓、電流、溫度、壓力、流量等信號進(jìn)行實時采集,并且對信號采集的實時性要求越來越高。傳統(tǒng)溫度采集方式則是采用單片機或DSP作為控制核心來設(shè)計溫度監(jiān)測系統(tǒng)。然而,這種方式存在一定的缺陷,不能滿足許多高要求的信號采集場合。一方面,此系統(tǒng)的大多數(shù)功能都是通過軟件來實現(xiàn)的,而軟件的運行會占據(jù)一部分系統(tǒng)采樣時間,從而降低系統(tǒng)采集速率;另一方面,系統(tǒng)對復(fù)雜外圍電路的邏輯也不能很好地控制。而現(xiàn)場可編程門陣列(FPGA)具有并行處理性,可控性,處理速度快等特性,因此,以FPGA為控制核心的信號采集系統(tǒng)可實現(xiàn)高速信號采集。本論文主要包含五大部分:第一部分為緒論部分,論述了本設(shè)計的研究背景,國內(nèi)外現(xiàn)狀,以及設(shè)計的主要研究內(nèi)容;第二部分設(shè)計了數(shù)據(jù)采集板硬件電路,主要設(shè)計了溫度信號采集模塊,溫度數(shù)據(jù)顯示模塊,FPGA基本配置模塊,無線通信模塊,電壓采集模塊的硬件電路;在FPGA程序設(shè)計部分,依次對AD9280電壓采集模塊,DS18B20的溫度采集模塊,數(shù)據(jù)緩存模塊,數(shù)據(jù)無線發(fā)送模塊等進(jìn)行了控制設(shè)計;第四部分為PC軟件設(shè)計,以Labview為設(shè)計平臺,設(shè)計出PC監(jiān)控系統(tǒng);最后,進(jìn)行了系統(tǒng)調(diào)試,先對系統(tǒng)的硬件部分進(jìn)行測試,之后將系統(tǒng)的軟硬件結(jié)合,對整個系統(tǒng)進(jìn)行了可靠性測試。本論文給出了系統(tǒng)采集部分的控制原理,對數(shù)據(jù)顯示控制核,數(shù)據(jù)轉(zhuǎn)換控制核進(jìn)行仿真,并對整個溫度采集電路進(jìn)行了驗證;設(shè)計出了 AD9280電壓采集的控制核,并對其進(jìn)行實際驗證;結(jié)合FIFO的工作原理,設(shè)計了同步FIFO作為采集系統(tǒng)的存儲模塊;詳細(xì)描述了在線配置藍(lán)牙模塊相關(guān)參數(shù)的方法,并基于藍(lán)牙模塊無線通信的原理,給出了藍(lán)牙通信的程序設(shè)計,同時對通信控制核進(jìn)行了仿真;設(shè)計了以FPGA為核心的整個溫度采集硬件控制電路的頂層模塊,對系統(tǒng)硬件控制部分中的子模塊進(jìn)行了模塊互連,對其進(jìn)行測試;設(shè)計了 PC監(jiān)控端,并結(jié)合硬件控制電路進(jìn)行了反復(fù)測試,將采集到的數(shù)據(jù)傳給PC端進(jìn)行分析,最后完成了高速信號采集的無線監(jiān)控系統(tǒng)設(shè)計。系統(tǒng)采用FPGA芯片EP2C8Q208C8N來搭建整個系統(tǒng)的硬件控制電路,舍棄了傳統(tǒng)的傳感器搭配外圍電路的思想,直接采用智能傳感器與FPGA相結(jié)合的方式。此外,系統(tǒng)中的存儲器采用FPGA的內(nèi)部資源(FIFO),可以在線配置。在藍(lán)牙2.0模塊的基礎(chǔ)上搭建無線傳輸模塊,在Labview的平臺上設(shè)計了 PC監(jiān)控端。以這樣的思路搭建系統(tǒng)的硬件部分大大地降低了采集系統(tǒng)的復(fù)雜性。系統(tǒng)經(jīng)過反復(fù)測試,測試結(jié)果表明該設(shè)計適用于精度為0.5℃的無線實時監(jiān)控系統(tǒng)。
[Abstract]:With the continuous progress of science and technology, national defense, astronomy, industry, agriculture and other fields often need to voltage, current, temperature, pressure, flow and other real-time signal acquisition, and the real-time signal acquisition requirements more and more high. The traditional temperature acquisition is the use of single chip computer or DSP is used as control core to design a temperature monitoring system this way. However, there are some defects, can not meet the requirements of many high signal acquisition occasions. On the one hand, most of the features of this system are realized by software, and the operation of the software will occupy a part of the system sampling time, and reduce the system acquisition rate; on the other hand, the system logic of complex peripheral the circuit is not controlled well. The field programmable gate array (FPGA) with parallel processing, controllability, processing speed and other characteristics. Therefore, the signal acquisition system control core based on FPGA Can achieve high-speed signal acquisition. This paper mainly includes five parts: the first part is introduction, discusses the research background of this design, the status quo at home and abroad, and the main contents of the design; the second part design the hardware circuit of data acquisition board, the main design of the temperature of the temperature signal acquisition module, data display module, FPGA configuration module, wireless communication module, the hardware circuit of the voltage acquisition module; the FPGA program design, in order to AD9280 voltage acquisition module, temperature acquisition module of DS18B20, the data cache module, wireless data transmission module for the control design; the fourth part is the software design of PC, with Labview as the design platform, the design of PC monitoring finally, the system; the system debugging, the first test of the hardware part, the system software and hardware combination of the whole system reliability test. This paper introduces the control principle of the data acquisition part of the system, display and control of nuclear, nuclear data conversion control is simulated, and the temperature acquisition circuit was verified; designed the control of nuclear AD9280 voltage acquisition, and tested the combination; FIFO of the work principle, design a synchronous FIFO as storage module acquisition system; the method of online configuration of Bluetooth module parameters described in detail, and based on the principle of Bluetooth wireless communication module, gives the program design of Bluetooth communication, the communication control core was simulated; the top-level module is designed with FPGA as the core of the temperature acquisition hardware control circuit, the control system hardware part in the sub module of the module interconnection, the test; design the PC monitoring terminal, combined with the hardware control circuit of repeated testing, the data collected will be sent to the PC The end is analyzed, finally completed the design of the wireless monitoring system of high speed signal acquisition. The system adopts FPGA chip EP2C8Q208C8N to build the whole system hardware control circuit, abandoning the traditional sensor collocation of peripheral circuit, directly using intelligent sensor and FPGA combination. In addition, the memory system using the FPGA internal resources (FIFO), online configuration. To build a wireless transmission module based on Bluetooth 2 module on the Labview platform in the design of PC monitoring terminal. The hardware part greatly in this way to build a system to reduce the complexity of the system acquisition system. After repeated testing, the test results show that the design is suitable for precision for wireless the real-time monitoring system of 0.5 degrees.
