For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, a schematic structural diagram of a testing device for a magnetic induction distance fuze provided by an embodiment of the present invention is shown, and details are as follows:
as shown in fig. 1, a test device 1 for a magnetically induced distance fuze includes: 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 used for acquiring a test signal, sending the test signal to the magnetic induction distance fuze, and the test signal is used for indicating the magnetic induction distance fuze to be electrified; generating a pulse signal according to the test signal, and transmitting 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 fuze based on the pulse signal;
the control module 13 is used for collecting the ignition signal of the magnetic induction distance fuze and sending the ignition signal to the control module 13;
the control module is also used for processing the ignition signal to obtain the test result of the magnetic induction distance fuze.
Currently, based on the functional principle of a magnetic induction distance fuze, the comprehensive performance measurement of the magnetic induction distance fuze requires magnetic induction distance fuze turn number setting equipment, magnetic induction distance fuze circuit charging equipment, an oscilloscope and analog magnetic field equipment. The existing measuring equipment is used for testing, a testing environment needs to be built, and the defects are as follows: 1. the charging quantity cannot be accurately controlled, and the consistency of each measurement cannot be ensured; 2. the measurement result is required to be manually subjected to data analysis, and errors are easy to occur in manual measurement for a long time; 3. the simulated magnetic field environment needs to be built, and the consistency of each measurement cannot be ensured; 4. the whole test environment is required to be constructed manually, and the measurement steps are complicated; 5. since the magnetic induction distance fuze is an electromechanical fuze, there is a possibility of causing irreversible damage to the circuit due to artificial misoperation during measurement. 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 a worker, and indicates that the magnetic induction distance fuze starts to be tested. Further, the operator can also input test parameters to the test device 1 to adjust the test items.
In the test process, after receiving the test signal, the control module 13 sends the test signal to the magnetic induction distance fuze to enable the magnetic induction distance fuze to be electrified and enter a working state, and meanwhile, generates a pulse signal and sends the pulse signal to the magnetic field simulation module 11 to enable the magnetic field simulation module 11 to generate a magnetic field environment when the magnetic induction distance fuze works. The magnetic induction distance fuze is placed in a magnetic field generated by the analog magnetic field module 11 during the test process and is connected with the signal acquisition module 12. After the controller in the magnetic induction distance fuze recognizes the ignition condition in the working environment simulated by the testing device 1, an ignition signal is sent out to detonate the ammunition, and at this time, the signal acquisition module 12 acquires the ignition signal and transmits the ignition signal to the control module 13. The control module 13 can determine the performance of the magnetically induced distance fuze by analyzing the ignition signal.
In some embodiments, the pulse signal is a PWM wave;
the analog magnetic field module 11 includes a waveform conversion unit and a helmholtz coil;
the waveform conversion unit is used for acquiring PWM waves, converting the PWM waves into sine waves, and applying the sine waves to Yu Hem Hotz coils to generate a magnetic field environment.
In this embodiment, the magnetic field simulation module 11 is used to provide a stable magnetic field close to the practical application environment for the magnetically induced distance fuze. In order to ensure the stability and adjustability of the analog magnetic field, in this embodiment, the analog magnetic field is generated by applying a set of sine wave signals to the helmholtz coils, and 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 a PWM wave generator is integrated on the single-chip microcomputer. The singlechip generates PWM waves based on the test signals, and then 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 conveniently adjusted. The waveform conversion unit may be a digital potentiometer.
The Helmholtz coils may take the form of printed circuit boards, flexible printed circuit boards, wire windings, and the like. When the Helmholtz coil in the wire winding form is used, a limit clamping groove can be arranged on a framework (bracket) wound by the wire to limit the distance between the coils in order to keep the wire winding consistency. The length and the number of turns of the lead wire are required to be set according to actual use conditions.
In some embodiments, the test device 1 further comprises a charging module; the control end of the charging module is connected with the control module 13; the output end of the charging module is connected with the battery module of the magnetic induction distance fuze;

the charging module is used for charging the battery module of the magnetic induction distance fuze after receiving the charging signal until the stored electric quantity of the battery module reaches the preset electric quantity.
In this embodiment, the working electric energy of the magnetic induction distance fuze is supplied by the battery module arranged inside the magnetic induction distance fuze, and the testing device 1 can also charge the battery module when necessary, so that the electric energy in the battery module meets the electric energy required to be consumed in the testing process. The charging module is used for generating a pulse signal to charge the battery module so as to simulate the magneto to supply power to the magnetic induction distance fuze in normal use.
In some embodiments, the firing signal includes a firing time and a voltage; the test result comprises a firing time delay and the voltage of a firing signal;
the control module 13 is further configured to obtain a transmission time of the test signal, and calculate a difference between the transmission time and the ignition time, so as to obtain an ignition time delay of the magnetic induction distance fuze.
In this embodiment, the magnetic induction distance fuze includes a self-destruction function, timing detonation is achieved through timing, and when the timing device in the magnetic induction distance fuze monitors that the preset time is reached, the controller in the magnetic induction distance fuze controls a level signal to be converted from a low level to a high level, namely, a firing signal is generated, the time when the level signal jumps from the low level to the high level is the firing time, and the voltage amplitude of the high level is the voltage of the firing signal. In addition, whether the firing signal successfully detonates the ammunition depends on the voltage amplitude of the firing signal. Therefore, to test the self-destruction function of the magnetic induction distance fuze, the time interval from the acquisition of the emission signal to the emission of the ignition signal, that is, the ignition time delay, and the voltage of the ignition signal need to be tested. The ignition time in this embodiment may be recorded by the control module 13, and the voltage of the ignition signal is collected by the signal collection module 12 and then sent to the control module.
In some embodiments, the signal acquisition module 12 may be further configured to detect a power supply voltage of the charging module for the magnetic induction distance fuze and a current operating voltage of the testing device 1 of the magnetic induction distance fuze, and then feed back the power supply voltage and the operating voltage to the control module, so that the control module regulates and controls the operating 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 also comprises a self-destruction function test result;
the control module 13 is also configured to: if the difference value between the ignition time delay and the preset time is smaller than the preset difference value threshold value, judging that the self-destruction function test result is qualified;
otherwise, judging the self-destruction function test result as unqualified.
In this embodiment, the preset time may be a self-destruction time preset in the magnetic induction distance fuze, or may be a self-destruction time sent to the magnetic induction distance fuze by the testing device 1 in the testing process, and the self-destruction function test result can be judged to be qualified only when the timing of the magnetic induction distance fuze is accurate and is 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 also configured to: if the voltage is greater than a preset voltage threshold, judging that the trigger function test result is qualified;
otherwise, judging that the trigger function test result is unqualified.
In this embodiment, the voltage amplitude of the firing signal may determine whether the firing signal can successfully fire the ammunition. Only if the voltage is larger than a 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 readings;
the control module 13 is further used for sending a fixed number of turns to the magnetic induction distance fuze so that the magnetic induction distance fuze realizes a distance frying function according to the fixed number of turns;
the control module 13 is further configured to obtain the number of readings of the magnetic induction distance fuze according to the ignition delay and the frequency of the sine wave.
In this embodiment, the magnetic induction distance fuze emits a firing signal when the number of turns detected by the magnetic induction distance fuze reaches a set number of turns, and the number of turns read is the number of turns that the magnetic induction distance fuze actually emits the firing signal in the test process and simulates rotation in the simulated magnetic field. The frequency of the sine wave signal will influence the parameters of the analogue magnetic field and the ignition delay depends on the number of readings of the magnetic induction distance fuze, so that the control module 13 can determine the number of readings of the magnetic induction distance fuze based on the frequency of the sine wave signal and the ignition delay.
In addition, the frequency and amplitude of the sine wave signal can directly influence the ignition time delay, so the control module 13 can also control the frequency and amplitude of the sine wave signal, generate a plurality of simulated magnetic fields with different parameters, and test a plurality of magnetic field environments of the magnetic induction distance fuze so as to obtain more accurate test results.
The test device 1 in this embodiment may further comprise an antenna, through which the control module 13 establishes an approach communication with the magnetic induction distance fuze to send a set number of turns to the magnetic induction distance fuze.
In some embodiments, the test results further comprise a par-fry test result;
the control module 13 is also configured to: if the difference value between the read turns and the set turns is smaller than the preset turn threshold value, judging that the distance frying test result is qualified;
otherwise, judging that the result of the distance frying test is unqualified.
In this embodiment, the number of readings accurately indicates that the distance function of the magnetic induction distance fuze is acceptable. The preset turn threshold can be adjusted according to the test accuracy.
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 fuze 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, and 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, so that the power consumption of the magnetic induction distance fuze needs to be tested. The working current of the magnetic induction distance fuze can be tested. After detecting the working current of the magnetic induction distance fuze, the control module can also compare the working current of the magnetic induction distance fuze with a preset current threshold, if the working current of the magnetic induction distance fuze is not greater than the preset current threshold, the test result of power consumption is judged to be qualified, otherwise, the test result of power consumption is judged to be unqualified.
