Design of Comprehensive Performance Test System for Residual Current Fire Monitoring Detector Based on Virtual Instrument Technology

Aiming at the need of detecting the residual current fire monitoring detector, an intelligent test system based on virtual instrument technology was designed. This system was composed of industrial computer, data acquisition card, signal conditioning circuit, three-phase great current generator and pneumatic fixture, etc. Using Lab VIEW virtual instrument technology platform, the related test and data processing program codes were developed, and its high speed data acquisition and data processing satisfied the needs of ex-factory comprehensive performance test for residual current fire monitoring detector. The hardware design was given and the working principles of this generator were introduced, the module design of system software was also introduced in detail. Practical application shows that the intelligent test system features with stable and reliable, easy to operate and maintain, high precision and can improve the design and performance of products, which can be widely used.
