The invention relates to a fault simulation device of a safety initiation device. The fault simulation device aims at solving the problems that case samples are used for motion checking and fault detection function examining in the development process of a unit tester, but the case samples can be damaged after being frequently used, the production and repair cost of the case samples is high, faults need to be artificially made, and the production efficiency and the testing reliability of the unit tester are affected. According to the fault simulation device, a programmable logic controller is matched with an external circuit and a touch screen to comprehensively simulate the fault type of the safety device, interfaces and equivalent loads the same as those of the case samples are designed, and the working switch and safety switch states of the safety device can be simulated. The fault simulation device is used for inspecting the motion checking and fault detection functions of the unit tester and provides the basis for guaranteeing the reliability of the safety initiation device.
Description
technical field [0001] The invention relates to a simulation technology, in particular to a safety detonation device fault simulation device, which is applied to the fault detection and action conversion function verification of the safety detonation device unit tester. Background technique [0002] The safety detonation device is a key component of the solid rocket motor. Its reliability is related to the success of the engine's launch. Whether its performance meets the overall requirements of the engine needs to undergo strict tests, including electrical performance tests, action checks and fault detection, so relevant tests are required. The device has the corresponding functions. The safety detonating device unit tester (referred to as the unit tester) is a special instrument used for the electrical performance test, action inspection and fault detection of the safety detonating device. After the development of the unit tester is completed, the functional and reliabilit...
