Fault diagnostic equipment of fire control system based on FTA

With regard to the disadvantages in maintenance support of fire control system, such as single function, poor versatility, low in test efficiency as well as poor reliability, a fault diagnostic test equipment is developed based on Fault Tree Analysis (FTA) and expert system. The fault tree is constructed with the failure of fire control system as top event. Then the qualitative analysis of fault tree is performed. The embedded equipment and industrial processing computer (IPC) are used in the design of hardware which is based on modular concept. The software of fault test equipment is modular and open-source and developed by LabWindows/CVI. In addition, if consists of multiple modules, such as system test, fault diagnosis, data management, self test and others. Database platform of Oracle and expert system are combined in the storage of test and diagnosis result as well as the inference and troubleshooting of system fault. This work indicates that FTA is an effective mean in fire control system fault diagnostic equipment.
