Fault Testing Device of Fire Control System Based on Virtual Instrumentation Technology
Computer Science & Service System（2012）
Abstract
The fire control system of the mine dispenser vehicle is the core of rocket launching and mine configuration. However it is prone to various faults and failures due to the complex battlefield environments. In this paper the fault testing device for fire control system with diversified functions, easier portability and better performance is designed and developed. The main work is as follows. The hardware platform of fault testing device consists of upper computer and lower computer. And the upper computer undertakes the display of diagnosis process, fault causes and troubleshooting results. It is mainly composed of industrial processing computer (IPC), touch screen, LCD and other peripheral interface. The lower computer is responsible for the acquisition, conditioning and connection of the electrical control signals. It contains two CPLD chips, signal conditioning circuit, serial interface as well as input interfaces for large amount of electrical control signals of the fire control system. In addition, the fault testing software application implements the display of diagnosis process, fault causes and troubleshooting results. It is developed by virtual instrumentation software platform LabVIEW. The fault testing device actually offers effective technical method in improving the repair and protection skills of mine dispenser vehicle.
