Detailed Description

The present invention will be described in detail below with reference to the drawings and the specific embodiments thereof, which are for explanation of the present invention only, but not for limitation of the present invention.

As shown in fig. 1, the invention discloses a mine fuse simulation device which is arranged on a training mine and comprises a digital sensor module, a fuse module and an internal memory module. According to the technical requirements of a digital fuze system, various mine working systems are required to be simulated, and fuze action data are recorded (recorded and stored), and as sound field and magnetic field data required by each mine type are different, an intelligent digital sensor is specially designed, a three-axis magnetic sensor and a broadband acoustic sensor of a physical field measurement system are utilized for digital processing, and physical field data required by each mine type of a fuze module are provided; the fuze module can simulate the working system of the multi-type submerged mine fuze, and mainly completes the data processing and algorithm by the singlechip; and the internal memory module records the fuze action information after the fuze module acts and stores the fuze data.

In order to meet the requirements of various analog mine sensors, digital sensors are designed and adopted, and the digital sensors comprise digital magnetic sensors and digital acoustic sensors.

The digital magnetic sensor provides magnetic field data for the digital fuze analog device, and the digital magnetic sensor adopts the analog signals output by the triaxial magnetic sensor to carry out digital processing, so that the required magnetic field data are obtained. A digital magnetic sensor block diagram is shown in fig. 2.

The digital magnetic sensor may digitally output the three-axis magnetic component, the total amount conversion rate, and the horizontal change rate. The digital magnetic sensor adopts a low-frequency filtering algorithm, and after the power-on, the digital magnetic sensor is used for adaptively measuring the geomagnetic field, compensating the geomagnetic field, and outputting a triaxial change signal, a change rate signal and a modulus change signal to the digital fuze singlechip.

The digital acoustic sensor collects the sound field signal of the sound conditioning circuit, carries out multichannel synchronous filtering, takes the envelope and digitally outputs the envelope to the digital fuze singlechip. A block diagram of the digital acoustic sensor is shown in fig. 3.

The acoustic signal conditioning module performs signal preprocessing such as amplification, filtering and the like on the output signals of the sound field sensor, and meets the signal acquisition requirement. The digital filter circuit is used for realizing digital filtering of various signals for the digital mines. The principle of the tone management circuit is shown in fig. 4.

According to the general technical requirements, the acoustic signal conditioning circuit mainly completes the conditioning function of the acoustic sensor output signal, and the main parameters are as follows: the band-pass filtering of 10 Hz-10 KHZ, the in-band fluctuation is less than or equal to 1dB, the stop band frequency of-30 dB is 19KHZ, the pass band gain is 40dB, the noise at the output end is less than or equal to 5mV, the power consumption is less than or equal to 20mW, and the sound conditioning signal and the sound envelope signal are output.

The digital fuse module comprises a digital fuse hardware design and a digital fuse software design. The digital fuze module simulates the working system of the mine fuzes such as MRP, stone fish and the like, and the digital fuze module mainly completes the data processing and algorithm by the singlechip.

After the digital fuze module is electrified, the digital magnetic sensor and the digital acoustic sensor output physical field data to the digital fuze singlechip; if the signal amplitude is larger than the specified threshold value, the digital fuze singlechip starts to analyze the received sound and magnetic digital signals according to the preset fuze working system, and digitally simulates the fuze working process according to the fuze algorithm.

According to the power consumption requirement of the measurement system, the magnetic sensor is designed with low power consumption, and a pulse power supply and micro-low power consumption processing chip is adopted, so that the system power consumption is reduced, and the system power consumption requirement is met; due to the reasons of processing technology and the like, the triaxial of the triaxial magnetic sensor is difficult to ensure absolute orthogonality, the error is basically controlled within 5 degrees, and meanwhile, the triaxial has sensitivity errors and residual magnetism effects, so that the measurement data has large errors, and the measurement accuracy is reduced. In order to improve measurement accuracy, a triaxial magnetic sensor output model is established, model parameters are solved by adopting a genetic algorithm and a nonlinear programming method, and digital correction is carried out on triaxial magnetic sensor output according to the model. According to theoretical calculation and measured data analysis, after the three-axis magnetic sensor is subjected to digital correction, the error of three-axis output of the three-axis magnetic sensor can be reduced by 90 percent to below 2nT, and the measurement precision of three components of the magnetic field is greatly improved.

The acoustic sensor uses a ring hydrophone developed in conjunction with the university of naval engineering and Hangzhou 715 institute.

The hydraulic sensor adopts a pressure transmitter developed by Shenzhen MEAS company, the naval engineering university mainly carries out low-power-consumption design aiming at the problem of overhigh power consumption of the sensor, and the MEAS company carries out overall structural design and improvement.
