The invention discloses an intelligent vibration sensor layout method based on cooperation of physical field modeling and hybrid optimization. The method comprises the steps that a geometric model of a target mechanical structure is acquired, and a material parameter set is extracted; the curvature and stress of the surface of the mechanical structure are calculated, and a high-sensitivity area is recognized in combination with a vibration transmission efficiency matrix; curvature self-adaptive sampling is executed in the high-sensitivity area, a candidate point set is generated based on an improved greedy algorithm, and redundant candidate points are eliminated to obtain an effective candidate point set; calculating coverage weights of the effective candidate points; adding the candidate point with the maximum coverage weight selected through bubble sorting into a sensor set, and calculating the total coverage rate once when each effective candidate point is added until the coverage rate reaches a preset value; performing global optimization based on a simulated annealing algorithm, and performing crossover and mutation operation on the selected sensor individuals; calculating the contribution degree of each sensor, and removing low-efficiency sensors until the maximum iteration value is reached. According to the invention, efficient calculation and resource configuration optimization are realized.

This invention belongs to the field of aviation electrical technology and discloses a bubble sorting method for serial-in and serial-out data based on FPGA. The FPGA uses a state machine for computation and sets a state jump pointer. At the end of each step, the state jump pointer is set to point to the state to which the next step is to jump. The sorting method includes the following steps: Step 1: Initialization; Step 2: Value retrieval; Step 3: Comparison of the last two bits; Step 4: Loop comparison; Step 5: Data output. This invention completes analog bubble sorting and filtering within the FPGA. For some smaller systems, it can eliminate the need for a CPU, saving costs while reducing the data transmission time between the CPU and FPGA, improving speed, and without affecting system stability.
