[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.
