The invention discloses a safety protection control system for a large on-board vibration platform. The safety protection control system comprises a signal processing function module and a state monitoring function module, wherein the signal processing function module is completely composed of hardware logic analog circuits, is connected with peripheral equipment or a peripheral system and an emergency brake button by virtue of an interface adapter socket and is used for processing a fault notification signal and a manual emergency brake signal which are externally input, performing automatic logical judgment on the input signals, generating brake signals of different timing sequences by virtue of a braking time sequence control circuit and outputting the signals to the peripheral equipment or peripheral system for performing braking control. The state monitoring function module is composed of an A / D board card and a computer and is used for monitoring the input and output states in real time by virtue of acquiring and monitoring software and transmitting fault warning in sound and light forms. The fault notification signal is transmitted from the peripheral equipment or system, and the braking time sequence control signal is output. Moreover, according to the system, safety protection control of the large on-board vibration platform is realized, and the safety of equipment on the vibration platform is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a safety protection control system and method for a large-scale airborne vibration platform. Background technique [0002] The airborne vibration platform provides simulated vibration environments of different frequencies for the test equipment to measure and analyze the state data of the equipment under vibration conditions. The large-scale vibrating table is composed of two sets of active and passive vibrating tables. The two sets of vibrating tables act in a coordinated manner according to instructions to form different vibration modes. Once the two sets of active and passive vibrating tables fail, it will cause a certain degree of damage to the equipment on the vibrating table or even serious hard damage. In this case, it is necessary to carry out emergency safety protection control on the vibration platform, monitor the failure of the vibration platfor...
