【摘要】：論文以基于無線傳輸的沖擊波超壓測試系統(tǒng)為應用背景，提出了一種基于ARM9的無線手持式控制終端的設計方案。 本文研究設計的手持控制終端應用于具有無線數據傳輸與控制功能的沖擊波超壓測試系統(tǒng)，該測試系統(tǒng)用來準確測量沖擊波的超壓峰值。沖擊波的超壓峰值和沖量是衡量彈藥炸藥威力的兩個重要參數，為研究武器系統(tǒng)的威力對比和性能評價提供重要依據，在國防、工業(yè)、生活等領域具有重要的意義。 基于ARM的手持終端設備應用于基于無線傳輸的沖擊波超壓測試系統(tǒng)，能快捷高效地實現(xiàn)與測試裝置之間指令和數據的傳輸。在爆炸場測試中，，由于測試現(xiàn)場環(huán)境比較惡劣，遠距離的無線傳輸存在信號弱、傳輸不穩(wěn)定的情況，而手持式控制終端能近距離的通過WiFi控制測試裝置，相比傳統(tǒng)的PC機終端，更加智能化、輕巧便攜、易于控制。 手持終端的設計包括以下四個部分：基于S3C2440處理器的硬件平臺搭建、軟件開發(fā)平臺的構建、相關驅動程序的編寫和移植、GUI界面應用程序的設計。本設計的硬件平臺選擇天塹公司的基于CPU S3C2440AL處理器的TQ2440開發(fā)板，S3C2440處理器是基于ARM920T內核的高性能多接口的嵌入式微處理器；軟件開發(fā)平臺根據宿主機——目標機的開發(fā)模式，首先完成了宿主機編譯環(huán)境的建立，包括Linux系統(tǒng)的安裝、交叉編譯器的安裝、文件系統(tǒng)制作工具Busybox和Qt4軟件的安裝。其次，建立了目標板的軟件環(huán)境，包括U-Boot、Linux內核和帶qt4.5的文件系統(tǒng)的編譯和移植；在宿主機環(huán)境下完成了無線網卡驅動程序的設計和編譯，并成功移植到目標機；使用Qt軟件完成了GUI界面程序的設計，實現(xiàn)了Qt應用程序向TQ2440目標板的移植。經過多次試驗驗證，本設計實現(xiàn)的手持控制終端符合基于無線傳輸的沖擊波測試系統(tǒng)的各項要求。
[Abstract]:In this paper, a design scheme of wireless handheld control terminal based on ARM9 is proposed based on the application background of shock wave overpressure test system based on wireless transmission. The handheld control terminal designed in this paper is applied to the shock wave overpressure test system with wireless data transmission and control function. The test system is used to accurately measure the overpressure peak value of the shock wave. The peak overpressure and impulse of shock wave are two important parameters to measure the power of ammunition explosive. It provides an important basis for comparing and evaluating the power of weapon system. It is of great significance in the fields of national defense, industry, life and so on. The handheld terminal device based on ARM is applied to the shock wave overpressure test system based on wireless transmission, which can quickly and efficiently realize the transmission of commands and data between the test device and the test device. In the explosion field test, because the environment of the test site is relatively bad, the remote wireless transmission exists weak signal and the transmission is unstable, and the handheld control terminal can pass the WiFi control test device at close distance, compared with the traditional PC terminal, More intelligent, lightweight and portable, easy to control. The design of handheld terminal includes the following four parts: the construction of hardware platform based on S3C2440 processor, the construction of software development platform, the programming and porting of related drivers, and the design of GUI interface application program. The hardware platform of this design selects the TQ2440 development board based on CPU S3C2440AL processor of Tianben Company. The S3C2440 processor is an embedded microprocessor with high performance and multi-interface based on ARM920T kernel. According to the development mode of the host-target computer, the software development platform firstly completes the establishment of the host compiler environment, including the installation of the Linux system, the installation of the cross-compiler, the installation of the file system production tool Busybox and the installation of the Qt4 software. Secondly, the software environment of the target board is set up, including the compilation and transplantation of the USB Boot, Linux kernel and file system with qt4.5, and the design and compilation of the driver of the wireless network card are completed in the host environment, and the driver is successfully transplanted to the target computer. Qt software is used to complete the design of GUI interface program, and the transplant of Qt application program to TQ2440 target board is realized. After many experiments, the design and realization of the handheld control terminal accords with the requirements of the shock wave test system based on wireless transmission.
