In the field of modern security protection and law enforcement, the integration of technology is constantly breaking the boundaries of traditional operations. Among them, the innovative combination of remote acoustic devices and robot dogs provides a new solution for safety protection in complex scenarios. As an enterprise focusing on acoustic technology, Ribri adheres to the concept of "protecting safety with sound". Its independently developed directional/omnidirectional acoustic devices are compatible with the flexible movement characteristics of robot dogs and show significant advantages in law enforcement, security, and other scenarios.
I. Faced Scenarios
In law enforcement and security practice, staff often face various high - risk and high - complexity scenarios: for example, in urban riot scenes, the crowd is dense and emotional, and close - range intervention is easy to trigger conflicts; in the scene of a chemical plant leakage accident, there is a risk of toxic gas diffusion, and personnel cannot approach to issue warnings; in the post - earthquake ruins area, the terrain is fragmented and there is a risk of secondary collapse, so it is necessary to deliver rescue information to the trapped people; in the security work of large - scale events, it is necessary to control specific areas from a long distance to avoid safety accidents caused by crowd gathering. In these scenarios, traditional methods such as manual information delivery and fixed equipment deployment either have potential safety hazards or have limited coverage, making it difficult to meet the needs of efficient and safe operations.
II. Customer Needs
For the above scenarios, the core needs of customers such as law enforcement departments and security enterprises show three directions. Firstly, there is a need for remote information transmission. Customers need to clearly transmit instructions, warning words, rescue guidance information, etc. to the target area within a safe distance of 50 - 500 meters to ensure that the recipients accurately obtain the content and avoid information distortion caused by excessive distance. Secondly, there is a need for non - contact deterrence. When dealing with troublemakers and illegal intruders, customers hope to form a deterrent through technical means, such as emitting high - decibel warning sounds, to avoid direct confrontation between personnel and reduce the risk of conflict escalation. Finally, there is a need for flexible deployment. Customers require that the equipment can quickly adapt to different terrains and environments, complete deployment and put into use within 30 minutes after receiving the task order, and at the same time, the equipment position and working mode can be adjusted in real - time according to the changes in the on - site situation.
III. Characteristics of Remote Acoustic Devices in This Scenario
Remote acoustic devices adapted to the above needs need to have targeted characteristics, and Ribri remote acoustic devices are typical representatives. Firstly, they have long - distance high - definition transmission. Relying on advanced acoustic amplification technology, the device can achieve a voice clarity of more than 90% within a distance of 300 meters. Even in a noisy environment, it can ensure that the target crowd accurately receives the information, solving the problem of "no sound at a long distance" of traditional devices.
Secondly, they have strong directivity and precise coverage. Through directional sound generation technology, the device can concentrate the sound energy within a specific angle range of 15 - 30 degrees, only acting on the target area, avoiding noise interference to the surrounding irrelevant people, and is especially suitable for law enforcement scenarios with dense crowds.
Thirdly, they have the ability to adapt to harsh environments. The device has passed the IP56 protection certification and can work normally in a temperature range of - 30°C to 60°C. At the same time, it has waterproof, dustproof, and anti - impact performance. Even in harsh conditions such as heavy rain, sand dust, and slight collisions, it can maintain stable operation, which is suitable for complex outdoor operation environments.
Fourthly, they have long - term battery life and convenient control. The device uses a high - efficiency battery, which can work continuously for more than 8 hours after a single charge, meeting the needs of long - time tasks. At the same time, it supports wireless remote control. Staff can adjust the volume and switch the voice content through a tablet or computer, which is convenient to operate and does not require on - site contact with the device.
IV. Combination and Integration with Other Equipment
Remote acoustic devices do not exist in isolation. Through integration with other equipment, a more comprehensive security operation system can be formed. When combined with high - definition intelligent cameras, the cameras can capture on - site images in real - time. After the staff identify the target area and personnel status through the images, they can control the acoustic device to deliver corresponding instructions synchronously, realizing the linkage of "visual monitoring + voice guidance". For example, in large - scale events, when the camera finds a crowd gathering, the acoustic device immediately sends an evacuation prompt. When integrated with a thermal imager, even in low - visibility environments such as night and heavy fog, the thermal imager can accurately locate the position of personnel or objects, guide the acoustic device to deliver information to specific targets, and solve the problem of "night blindness" of traditional devices. In addition, when combined with environmental sensors, it can monitor on - site data such as temperature, humidity, and harmful gas concentration in real - time. When the sensor detects that the environmental parameters exceed the safety threshold, the acoustic device automatically triggers the warning function to promptly remind the surrounding personnel to evacuate, further improving the safety of operations.
V. Advantages of Combination with Unmanned Equipment
As a mainstream unmanned mobile device, robot dogs, when combined with remote acoustic devices, can give full play to the advantages of both parties. The core advantages are reflected in four aspects.
1. Flexible Deployment and Comprehensive Coverage
Robot dogs have flexible movement capabilities driven by four limbs, and can easily cross complex terrains such as steps, gullies, and ruins. Their maximum climbing angle can reach 35 degrees, and the maximum obstacle - crossing height is 20 centimeters. They can quickly transport remote acoustic devices to areas that are inaccessible to humans. For example, in post - disaster ruins scenarios, robot dogs can carry devices deep into the interior of collapsed buildings to achieve information coverage in the depths of the ruins, breaking the limitation of traditional devices being "fixed in place" and expanding the operation range.
2. Reduce Personnel Safety Risks
In high - risk scenarios such as toxic gas leaks and riot conflicts, staff do not need to be present in person. They can remotely control robot dogs to carry acoustic devices to carry out work, avoiding direct exposure to dangerous environments. Data shows that the operation mode of "robot dog + remote acoustic device" can reduce the safety risks faced by personnel by more than 80%, significantly improving the safety of operations.
3. Real - time Response and Dynamic Adjustment
Robot dogs support 5G or 4G remote control, with a response delay of less than 0.5 seconds. Staff can adjust the movement route of the robot dog and the working state of the acoustic device in real - time according to on - site changes. For example, in riot handling, when the troublemaking crowd moves, the staff can immediately control the robot dog to follow and move, ensuring that the acoustic device always points to the target area and avoiding the failure of deterrence caused by fixed devices.
4. Lightweight and Convenient Transportation
Compared with traditional vehicle - mounted acoustic devices, the remote acoustic device carried by the robot dog weighs only 3 - 5 kilograms. The entire system can be transported by an ordinary SUV, and even can be carried to remote areas by 2 staff members. In scenarios with inconvenient transportation such as mountainous areas and rural areas, deployment can be quickly completed without complex transportation equipment, improving the task response efficiency.
VI. Specific Application Cases
In the handling of a riot incident in a coastal city in 2024, the local police used robot dogs equipped with Ribri remote acoustic devices for the first time. At that time, a sudden dispute in the central business district of the city caused a crowd to gather, and some people became emotional and engaged in smashing and looting. Traditional police forces faced the risk of conflict when intervening at close range. The police quickly dispatched 3 robot dogs, which carried Ribri directional acoustic devices and entered the periphery of the scene from different directions. Through remote control, the robot dogs moved to a safe position 150 meters away from the troublemaking crowd. The acoustic devices emitted clear legal warnings and evacuation instructions. At the same time, with the help of strong directivity technology, they only acted on the troublemaking crowd area and did not interfere with the surrounding shops and onlookers. During the 2 - hour handling process, the robot dogs adjusted their positions in real - time according to the movement trajectory of the crowd to ensure that the warning information was continuously covered. Finally, the troublemaking crowd was gradually evacuated under the deterrence of the acoustic devices and the guidance of the instructions, and the on - site order was restored to normal. No casualties occurred during the entire process, and the police completed the handling only through remote control, which fully verified the practical value of "robot dog + remote acoustic device" in law enforcement scenarios.
