In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.

as shown in fig. 1, a magnetic induction distance fuse testing device 1 comprises: the device comprises an analog magnetic field module 11, a signal acquisition module 12 and a control module 13;
the control module 13 is respectively connected with the analog magnetic field module 11 and the signal acquisition module 12;
the control module 13 is configured to obtain a test signal, and send the test signal to the magnetic induction distance fuse, where the test signal is used to indicate that the magnetic induction distance fuse is powered on; generating a pulse signal according to the test signal, and sending the pulse signal to the analog magnetic field module 11;
the analog magnetic field module 11 is used for generating a magnetic field environment required by the magnetic induction distance fuse based on the pulse signal;
the control module 13 is used for acquiring an ignition signal of the magnetic induction distance fuse and sending the ignition signal to the control module 13;
the control module is also used for processing the ignition signal to obtain a test result of the magnetic induction distance fuse.
At present, on the basis of the functional principle of a magnetic induction distance fuse, a magnetic induction distance fuse circle number setting device, a magnetic induction distance fuse circuit charging device, an oscilloscope and an analog magnetic field device are required for measuring the comprehensive performance of the magnetic induction distance fuse. The existing measuring equipment is used for testing, a testing environment needs to be built, and the defects are as follows: 1. the charging electric quantity cannot be accurately controlled, and the consistency of each measurement cannot be ensured; 2. the data analysis of the measurement result needs to be carried out manually, and the manual measurement is easy to generate errors for a long time; 3. a simulated magnetic field environment needs to be built, and the consistency of each measurement cannot be ensured; 4. an integral test environment needs to be manually set up, and the measurement steps are complicated; 5. since the magnetically inductive distance fuses are electromechanical fuses, there is the possibility of irreversible damage to the circuit during measurement due to human operator error. Generally, the existing measuring technology has the disadvantages of complex operation, poor consistency of measuring environment, low reliability, low accuracy and low efficiency.
In this embodiment, the test signal is a signal input by the operator, which indicates that the magnetic induction distance fuze is to be tested. Further, the worker may input test parameters to the test apparatus 1 to adjust the test items.
In the testing process, after receiving the test signal, the control module 13 sends the test signal to the magnetic induction distance fuse to electrify the magnetic induction distance fuse and enter a working state, and meanwhile, generates a pulse signal and sends the pulse signal to the simulated magnetic field module 11 to enable the simulated magnetic field module 11 to generate a magnetic field environment when the magnetic induction distance fuse works. The magnetic induction distance fuses are placed in the magnetic field generated by the analog magnetic field module 11 during the test and are connected to the signal acquisition module 12. After the controller in the magnetic induction distance fuse recognizes the firing condition in the working environment simulated by the testing device 1, a firing signal is sent out to detonate the ammunition, and at the moment, the signal acquisition module 12 acquires the firing signal and transmits the firing signal to the control module 13. The control module 13 can determine the performance of the magnetic induction distance fuze by analyzing the firing signal.
In some embodiments, the pulse signal is a PWM wave;
the analog magnetic field module 11 comprises a waveform conversion unit and a Helmholtz coil;
the waveform conversion unit is used for acquiring a PWM wave, converting the PWM wave into a sine wave and applying the sine wave to the Helmholtz coil to generate a magnetic field environment.
In the present embodiment, the analog magnetic field module 11 is used to provide a stable magnetic field close to the practical application environment for the magnetic induction distance fuze. In order to ensure the stability and adjustability of the analog magnetic field, in the embodiment, the analog magnetic field is generated by applying a set of sine wave signals to the helmholtz coil, and the parameters of the analog magnetic field are adjusted by adjusting the amplitude and frequency of the sine wave signals. In this embodiment, the control module 13 may be a single chip microcomputer, and the single chip microcomputer is integrated with a PWM wave generator. The single chip microcomputer generates PWM waves based on the test signals, and the PWM waves are converted into sine wave signals through the waveform conversion unit, so that the frequency and the amplitude of the sine wave signals can be adjusted conveniently. The waveform converting unit may be a digital potentiometer.
The helmholtz coil may take the form of a printed circuit board, a flexible printed circuit board, a wire wound coil, etc. When the Helmholtz coil in the wire winding form is used, in order to keep the wire winding consistency, a limiting clamping groove can be arranged on a framework (support) for winding the wire, so that the distance between the coils is limited. The length and the number of turns of the lead are required to be set according to actual use conditions.
In some embodiments, the testing device 1 further comprises a charging module 14; the control end of the charging module 14 is connected with the control module 13; the output end of the charging module 14 is connected with a battery module of the magnetic induction distance fuse;

In this embodiment, the working electric energy of the magnetic induction distance fuse is supplied by the battery module arranged inside the magnetic induction distance fuse, and when necessary, the testing device 1 can also charge the battery module, so that the electric energy in the battery module satisfies the electric energy required to be consumed in the testing process. The charging module 14 is used for generating a pulse signal to charge the battery module so as to simulate the power supply of the magneto to the magnetic induction distance fuse in normal use.
In some embodiments, the firing signal includes a firing time and a voltage; the test result comprises an ignition delay and the voltage of an ignition signal;
the control module 13 is further configured to obtain a sending time of the test signal, and calculate a difference between the sending time and the firing time to obtain a firing time delay of the magnetic induction distance fuse.
In the embodiment, the magnetic induction distance fuse comprises a self-destruction function, timing detonation is realized by timing, when a timing device in the magnetic induction distance fuse monitors that preset time is reached, a controller in the magnetic induction distance fuse controls a level signal to be converted from a low level to a high level, namely, an ignition signal is generated, the moment when the level signal jumps from the low level to the high level is the ignition time, and the voltage amplitude of the high level is the voltage of the ignition signal. In addition, the success of the firing signal in detonating the ammunition depends on the voltage amplitude of the firing signal. Therefore, to test the self-destruction function of the magnetic induction distance fuse, the time interval from the acquisition of the emission signal to the emission of the ignition signal, i.e. the ignition delay, and the voltage of the ignition signal need to be tested.

In some embodiments, the signal acquisition module 12 may also be configured to detect a power supply voltage of the magnetic induction distance fuse and a current working voltage of the testing device 1 of the magnetic induction distance fuse, which are provided by the charging module 14, and then feed the power supply voltage and the working voltage back to the control module, so that the control module regulates and controls the working state of the testing device 1.
On the basis of the previous embodiment, after the ignition time of the ignition signal is obtained, the test result further comprises a self-destruction function test result;
the control module 13 is further configured to: if the difference value between the ignition time delay and the preset time is smaller than a preset difference value threshold value, judging that the self-destruction function test result is qualified;
otherwise, judging that the self-destruction function test result is unqualified.
In this embodiment, the preset time may be a self-destruction time preset in the magnetic induction fixed-distance fuze, or may be a self-destruction time sent by the testing apparatus 1 to the magnetic induction fixed-distance fuze in the testing process, and the self-destruction function testing result can be determined to be qualified only when the timing of the magnetic induction fixed-distance fuze is accurate and close to the preset time.
On the basis of the previous embodiment, after the voltage of the ignition signal is obtained, the test result further comprises a trigger function test result;
the control module 13 is further configured to: if the voltage is greater than the preset voltage threshold, judging that the trigger function test result is qualified;
otherwise, judging that the test result of the trigger function is unqualified.
In this embodiment, the voltage amplitude of the firing signal may determine whether the firing signal successfully detonates the ammunition. Only if the voltage is greater than the preset voltage threshold value, the trigger function test result can be judged to be qualified.
In some embodiments, the test results include a number of turns read;
the control module 13 is also used for sending the set number of turns to the magnetic induction distance fuse so as to enable the magnetic induction distance fuse to realize the distance-fixing function according to the set number of turns;
the control module 13 is further configured to obtain the number of read turns of the magnetic induction distance fuse according to the ignition time delay and the frequency of the sine wave.
In this embodiment, the number of revolutions that magnetic induction distance fuse detected can send out the signal of starting a fire when reaching the number of revolutions of dress, reads the number of revolutions for the magnetic induction distance fuse and simulates rotatory number of revolutions in the simulated magnetic field when actually sending out the signal of starting a fire in the testing process. The frequency of the sine wave signal influences the parameters of the simulated magnetic field and the ignition time delay depends on the number of read turns of the magnetic induction distance fuze, so that the control module 13 can determine the number of read turns of the magnetic induction distance fuze based on the frequency of the sine wave signal and the ignition time delay.
In addition, because the frequency and amplitude of the sine wave signal directly affect the ignition time delay, the control module 13 can also control the frequency and amplitude of the sine wave signal to generate various simulated magnetic fields with different parameters, and perform various tests in different magnetic field environments on the magnetic induction distance fuse, so as to obtain a more accurate test result.

In some embodiments, the test results further comprise distance burst test results;
the control module 13 is further configured to: if the difference value between the read number of turns and the set number of turns is smaller than the preset number of turns threshold, judging that the distance explosion test result is qualified;
otherwise, judging that the distance explosion test result is unqualified.
In the embodiment, the number of reading circles accurately represents that the distance function of the magnetic induction distance fuse is qualified. The preset turn number threshold value can be adjusted according to the test precision.
In some embodiments, the test results include an operating current;
the signal acquisition module 12 includes a current detection unit; the current detection unit is connected with the control module 13;
the current detection unit is used for detecting the working current of the magnetic induction distance fuse and sending the working current to the control module 13.
In this embodiment, the magnetic induction distance fuze needs to consume electric energy in the process of judging the ammunition firing state, if the electric energy is consumed too fast, the electric energy in the battery module of the magnetic induction distance fuze may not be enough to detonate the ammunition, and therefore the power consumption of the magnetic induction distance fuze also needs to be tested. In particular to test the working current of the magnetic induction distance fuse. After the working current of the magnetic induction distance fuse is detected, the control module can also compare the working current of the magnetic induction distance fuse with a preset current threshold, if the working current of the magnetic induction distance fuse is not greater than the preset current threshold, the power consumption test result is judged to be qualified, and otherwise the power consumption test result is judged to be unqualified.
