Temperature measurement technology, accuracy and application of temperature measurement walk through metal detector gates
At present, there are two common temperature measurement technologies used in the temperature measurement walk through metal detector gates, among which the infrared thermal imaging probe technology is the one with high temperature measurement accuracy. The technology uses the infrared thermal imaging probe to measure the temperature accurately with an error of 0.1-0.3 ℃, and the mature security inspection technology with fast temperature measurement speed, door structure and combination of the security door is widely used in various bus stations, railway stations and schools, Hospitals, ports, airports and other densely populated places.
The temperature measurement walk through metal detector gates independently developed by Suzhou aoteng Electronic Technology Co., Ltd. adopts infrared thermal imaging probe, which has high temperature measurement sensitivity, area array imaging, fast temperature measurement speed, high temperature measurement accuracy, and temperature measurement error of 0.1-0.3 ℃. Under normal circumstances, it can be measured by 40-60 people per minute, and has multiple extended structures, which can expand RJ45 network interface, USB serial port for network management, and can use face Identification and human identification module, especially for schools, office buildings, hospitals and other personnel in and out of frequent, human card needs human card occasions.
In view of the problem of temperature measurement object rising in school, the right side of temperature measurement walk through gates can be designed with slide rail, and the temperature measurement probe can be adjusted according to the height of temperature measurement object.
The temperature measurement walk through gates adopts the visual design of sound and light alarm. When the temperature of the person to be measured is higher than the set temperature threshold, the temperature measurement walk through gates will send out sound and light alarm to remind the temperature measurement staff that the temperature of the person to be measured is abnormal. The staff can use the requirements to retest, or use the forehead temperature gun and mercury thermometer to repeatedly detect the temperature of the person with abnormal temperature measurement.
The working temperature of the temperature measuring metal detector gate is - 20 ~ 55 ℃, which can be used for temperature measurement in low temperature environment.
