at disaster sites such as building collapses, we can often see trained rescue dogs using their sensitive sense of smell to search for trapped survivors. They can squeeze into areas where rescuers can’t. Now, the rescue dog has a new intelligent safety belt, which can play a greater role by collecting and sending important information about its environment
developed by Alper Bozkurt and David Roberts of North Carolina State University, this smart seat belt is a part of smart emergency response system (SERS). Other parts of the system are developed by other organizations in the United States, including UAVs and robots. Once the SERS is started, the three parts can be deployed at the same time, work together and share data through the computer interface
Bozkurt and Roberts start with the existing rescue dog safety belt, and then add various sensors that can monitor the environment, monitor the rescue dog and communicate
environmental sensors include cameras, microphones and GPS. Staff can also add specific sensors according to actual needs, such as gas sensors or Geiger counters. Sensors can wirelessly transmit data to other SERS parts, including the central command center or nearby handheld devices
sensors can not only let rescuers know which situations endanger them or the rescuer, but also let them know whether the rescue dog is in danger. An additional set of sensors can detect the physiological function and behavior of the rescue dog, and transmit the heart rate and other data of the rescue dog. This information can let users know the situation of the rescue dog and whether the rescue dog is excited by the smell
this intelligent safety belt communication system allows the trainer to convey verbal instructions to the rescue dog through the loudspeaker on the safety belt. 1n addition, researchers are developing a tactile system that communicates commands through vibrating motors embedded in seat belts. But Roberts was quick to point out that vibration is for promotion, not punishment, and that trainers use a reward mechanism when training rescue dogs to respond to vibration
a team at Auburn University in Alabama is developing a similar system to convey the trainer’s orders through loudspeakers and motors on the seat belt
