How does sensor technology show its charm?
Recently, a sudden outbreak of pneumonia caused by a new coronavirus infection has swept across everyone's hearts. First-level responses to major public health emergencies have been initiated in many places, and a campaign to stop the spread of the epidemic and prevent further spread has begun. In this national emergency operation battle, in addition to epidemic protection supplies and facilities, a large number of cutting-edge new technologies such as 5G, artificial intelligence, and virtual reality have begun to be applied. New medical technologies such as intelligent ventilators, monitors, oxygen generators, and negative pressure ambulances have appeared on the front line of epidemic prevention and control, and played a major role in the rescue of critically ill patients and the suppression of virus spread. This shows that the effectiveness of high-tech products in helping to prevent and control the epidemic, and the role they play in responding to various emergencies cannot be ignored. Of course, as the basic technology and core components for various data collection of the epidemic, the key role of the sensor is incomparable. Among them, the eight sensitive components and sensors such as sound sensitivity, force sensitivity, magnetic sensitivity, gas sensitivity, light sensitivity, temperature and humidity, RFID radio frequency, media biology (test paper, enzyme electrode) are applied to various prevention and control measures and scenarios without exception. China has its irreplaceability.
Because the common symptoms of patients diagnosed with the new coronavirus are mainly respiratory infections, fever, cough, shortness of breath, or dyspnea, the sensor plays a major role in the control of the epidemic.
Application of infrared sensor technology in body temperature screening
From the current symptoms, although "fever" is not the only indicator for judging the infection of pneumonia (some mild cases do not have fever, but fever must be severe), but before there is a completely accurate and effective method, temperature detection becomes a judgment Key indicators of infection. In this way, in the face of the huge floating population in public places, it is important to quickly and accurately detect and screen abnormal body temperature in a mobile state. Of course, this is not a difficult issue for non-contact infrared thermometers. Whether it is a vertical infrared thermometer or a handheld ear thermometer, infrared thermometer and other infrared detection equipment, it can accurately meet the accuracy requirements. . In this kind of equipment, the main function is an infrared temperature sensor that can meet the requirements of medical metrology standards and parameter indicators with high accuracy, high reliability, high stability and consistency.
Infrared thermometer is composed of optical system, photodetector, signal amplifier, signal processing and display output. The thermal image signal of the human body's infrared radiation is transmitted to the modulator through the optical receiver. After eliminating a large area of background interference signals, the thermal image signal of the infrared radiation is converted into an electrical signal, and then processed by an amplifier and signal. After the built-in algorithm and target emissivity are corrected, the temperature is finally converted to the measured target. In short, after receiving the energy from the object, the infrared sensor converts the infrared energy into an electrical signal through its optical system, and converts it into a medical-grade high-precision temperature value through model algorithms and parameter calibration. Compared with other types of temperature measurement methods, the advantages of infrared temperature measurement methods are fast, intuitive, and non-contact detection.
