Description

Technical Field

[0001] This utility model relates to a jamming device, specifically a jamming device for communication training of armored vehicles, belonging to the field of military communication simulation training technology. Background Technology

[0002] In modern armored vehicle communication training, simulating battlefield interference with communication systems is a crucial means of achieving realistic training. Jamming devices, as core equipment in training simulations, are widely used for jamming and monitoring communication signals. Common jamming methods include electromagnetic interference and audio interference, simulating the interference experienced by communication equipment in complex environments through the injection of jamming signals.

[0003] Existing communication jamming devices typically achieve their function in two ways: first, by using a buzzer or signal generator to generate interfering audio signals, thereby creating sensory interference for personnel in the training environment through sound waves; second, by injecting interference signals into the input terminal (radio microphone interface) of the communication equipment to directly disrupt the signal transmission function of the communication equipment.

[0004] However, due to the limited internal space of armored vehicles and the diverse mission requirements, existing jamming devices struggle to achieve a reasonable balance between functionality and size. Furthermore, their ability to generate and adjust jamming signals is limited, and existing equipment typically cannot precisely control signal frequency and amplitude, resulting in insufficient jamming effectiveness. Secondly, the devices are large in size and consume a lot of power, making them difficult to adapt to the limited space and power conditions inside armored vehicles. This, in turn, affects the authenticity and effectiveness of communication training.

[0005] In view of the above, in order to overcome the above technical problems, this utility model designs an interference device for communication training of armored vehicles, thus solving the above technical problems. Summary of the Invention

[0006] The technical objective of this invention is to provide a small, low-power, and flexible jamming device by splitting the interference signal into two paths: one path drives a buzzer to achieve sound interference, and the other path injects an electromagnetic interference signal through a radio interface. This solves the problems of limited functionality and large size of existing jamming devices for armored vehicle communication equipment.

[0009] The core processing module mainly consists of a microcontroller and a minimum system circuit. The microcontroller's Timer 0 or Timer 1 generates a PWM (Pulse Width Modulation) signal, which drives the buzzer through an I / O port. By adjusting the timer's counting period, the pulse frequency output to the buzzer is changed, thereby controlling the tone.

[0010] Music playback involves determining pitch and rhythm. Pitch is determined by frequency, with different notes corresponding to different frequencies. The core processing module achieves this by setting the prescaler and initial count value of a timer. Rhythm, on the other hand, is the temporal structure of the music, achieved by controlling the duration of each note. In the microcontroller of the core processing module, this is accomplished through delay functions or interrupt service routines.

[0067] The principle behind this invention is as follows: The sound source simulated by the microcontroller can be divided into two paths. One path can amplify the sound through a buzzer, producing different pitches by changing the voltage frequency. The timer and interrupt functions in the microcontroller are crucial for controlling the buzzer, as precise control of the pulse width is needed to change the frequency and thus the pitch. The microcontroller outputs a PWM wave from its input / output port, which passes through an RC low-pass filter, then through a DC blocking circuit, is amplified, and finally connected to the buzzer. From a filtering perspective, a low-pass filter removes the AC component of the PWM wave, leaving only the DC component.

[0068] Another option is to use a short-circuit pointer to connect to the microphone input of the TCR-96A radio without using the buzzer, thus allowing the interference signal to enter the TCR-96A radio.
