Infrared ranging sensor is usedinfraredMediameasurement system , which can be divided into five categories according to functions: (1)radiometerFor radiation andSpectral measurement；(2) Search andtracking system, used to search and track infrared targets and determine theirspatial location And track its movement;(3) Thermal imaging system, which can generate the whole targetinfrared radiationDistribution image of;(4) Infrared ranging andcommunication system ；（5）hybrid systemRefers to the combination of two or more of the above systems.According to the detection mechanism, it can be divided intoPhoton detectorandHeat detector。infra-redSensing technologyIt has been widely used in modern science and technology, national defense, industry and agriculture.
Recently, the globalnatural disasterFrequent, such as SichuanChileThe earthquake and tsunami in Japan have seriously affected human life safety, and the second disaster has brought great risks to rescuers. At this time, search and rescue robots can well replace rescuers to search and rescue trapped people.Sensors are indispensable devices for search and rescue robots. There are many kinds of sensors on robots, including infrared ranging sensors.
Athletic ability, perception, communication andOperation abilityThe search and rescue robot must have several abilities, such as.The communication operation ability of search and rescue robot depends on the good movement ability and perception ability of the robotPerceptionIt is based on the effective use of sensors.infrared sensor The application on the search and rescue robot is equivalent to the function of the human eye. The infrared ranging sensor used emits a beaminfrared light, form a reflection process after the object is irradiated, receive the signal after the reflection to the sensor, and then useimage processingReceive the data of the time difference between transmission and reception.throughSignal processorCalculate the distance of the object after processing.This can be used not only for natural surfaces, but also for adding reflective plates.Measuring distanceFar, very highfrequency response, suitable for harsh industrial environment.
Robots have always been a hot topic in recent years. Robots can do many things that people can't do, especially in the search and rescue work after a disaster. Robots play a huge role. Robots' functions are developed on the basis of sensors, so only advancedsensor technology To produce high-performance robots.
