Abstract:In order to remotely control all target equipment in the field range and display the target status and firing performance in real time, a remote control system of field range equipment based on ni-visa is developed. According to the selected development platform and language, the working mode of the upper computer is divided, and then the connection form of the database table is standardized with the help of the three-tier control architecture, so as to interfere with the real-time connection form of the communication module and complete the upper computer software design of the remote control system. On this basis, define the order of magnitude level of serial port bytes, process the imported data information by configuring the remote serial port, combine the program block diagram system, realize the remote control program design based on ni-visa, and complete the development and design of the remote control system software of field target equipment combined with the key host computer application structure. The experimental results show that the application software based on ni-visa provides a variety of working modes, can control all target equipment at the same time, make it display the real shooting performance, and can better adapt to a variety of different shooting training needs.
