A device and method for improving command and communication capabilities in a high-noise environment in a vehicle

Abstract

The present invention provides a device and method for improving command and communication capabilities in a high-noise environment in a vehicle, including a tandem machine, a communication controller, a plurality of noise reduction earphones and a voice adapter, wherein: the communication controller is connected to the tandem through a CCU interface A plurality of noise reduction earphones are connected to the tandem machine through a voice adapter; the noise reduction earphones include paired earphones and ordinary earphones, and the paired earphones can control and send PTT, and enter the communication controller through the CCU interface to communicate with the superior command center; ordinary Both the headset and the paired headset can implement internal conferences. The invention optimizes the sound mixing algorithm, adopts the ASW self-alignment weight mixing algorithm, and reasonably allocates the authority of each earphone, ensures that each trumpeter has a clear division of labor, and each performs its own duties, thereby improving communication efficiency. 500 meters can be realized through the voice adapter. The voice adapter has a compact design and is easy to carry, which greatly improves the activity space of the trumpeter and is convenient for performing tasks outside the vehicle.

Description

technical field [0001] The invention relates to the field of tactical communication command, in particular to a device and method for improving command communication capability in a high-noise environment inside a vehicle. Background technique [0002] As a small combat unit, each combat vehicle is assigned a number of trumpeters, and each trumpeter has its own responsibilities. The communication and cooperation between the trumpeters is particularly important. The command and communication system in the vehicle provides important support for the coordinated operations of the trumpeters in the vehicle. At present, the noise inside the combat vehicle of our army is very loud during the combat command. In the traditional command communication system in the vehicle, the voice processing mostly uses analog circuits, and multiple earphones are connected in series for communication. This design greatly reduces the noise of the dialogue. Operability, has many disadvantages: [00...

AI Technical Summary

Problems solved by technology

At present, the noise inside the combat vehicle of our army is very loud during the combat command. In the traditional command communication system in the vehicle, the voice processing mostly uses analog circuits, and multiple earphones are connected in series for communication. This design greatly reduces the noise of the dialogue. Operability, has many disadvantages:

[0003] 1. The noise reduction ability is not strong

The noise in the car can sometimes reach 100DB or higher, and only relying on the noise reduction of the analog circuit in the headset cannot meet the demand

[0004] 2. Poor sound mixing effect

When using the internal conference function, if more than two people speak at the same time, the amplitude of the mixed voice will easily overflow, resulting in broken sound, and the poor quality will make it difficult to hear the instructions clearly.

[0005] 3. The distribution of roles and functions is unreasonable

Each headset has the same authority, it is easy for multiple people to control the transmission at the same time, which affects the communication between the two

[0006] 4. The operation of earphone control is cumbersome

In order to prevent the noise in the car from entering the earphones when idle, the earphones are designed with two gears for internal and external communication. It is easy for the trumpeter to hit the wrong gear when operating

[0007] 5. The headphone cable is too short, which limits the range of activities of the trumpeter

However, the above scheme does not realize the distribution of permissions, and limits the scope of activities of the trumpeter
