On February 3, 2020, Wuhan Huoshenshan Hospital officially began admitting patients, and Leishenshan Hospital is also about to be delivered. In order to better ensure the safety of medical staff fighting on the front line of epidemic prevention and control, Bonn instrument infrared human body temperature recorders have been installed in hospitals such as "Huoshenshan" and "Leishenshan" in Wuhan, as well as in hotels where doctors reside.These devices can continuously monitor the temperature status of medical staff 24 hours a day. Once someone experiences abnormal conditions such as fever, they can issue timely warnings, buy valuable treatment time for new infections, and prevent further spread of the coronavirus within the hospital.

Infrared human body temperature screening devicealso known asInfrared rapid screening device for human surface temperature, also known as infrared temperature screening device or infrared screening device,It is an instrument that can quickly detect the surface temperature of the human body without contact. The instrument consists of a core processing system, a display screen14 sets of temperature detectionThe hardware components include sensors, alarm devices, chassis brackets, and operating system software. It has the characteristics of non-contact, wide temperature range, short response time, fast screening speed, and high measurement accuracy. Using sensors imported from Belgium and utilizing the principle of infrared thermal radiation to quickly and effectively screen and measure the surface temperature of the human body. During the screening process, if a suspicious fever patient is found, the instrument immediately activates the alarm device, emits flashing indicator lights and voice broadcasts the detected surface temperature data of the human body. When linked to the network camera, access control, gate or other braking equipment, the linked equipment will react at the same time,Timely and effective prevention of cross flow of peoplebiographydyePrevent problems before they arise.

1The display screen adopts LCD dot matrix LCD display with backlight function, and data can be read clearly even at night;

3. The detection sensor is imported from Belgium, non-contact long-distance detection, safe and reliable. The sensor hasFeatures such as thermal gradient compensation and high screening accuracy, with effective detection range up to:1100mm；

5. Turn on the sound and light alarm device when the body temperature is too high to avoid cross infection caused by abortion. When the body temperature is normal, the green light indicates normal passage;

7. Adopting automatic compensation calibration technology for environmental temperature, the compensation calibration mode is automatically switched to effectively avoid the impact of changes in environmental temperature on the measurement accuracy of the screening instrument;

9. Equipped with a network camera and video monitoring system, it automatically captures and stores images of suspected fever in individuals with high body temperature, displaying the surface temperature of the human body (GD21-TY2B type).

1、 Introduction

The infrared body temperature screening device is an instrument that can quickly detect the body surface temperature of the human body. The person being tested can quickly measure the body surface temperature without stopping. Therefore, the infrared temperature screening device is particularly suitable for screening people with high body temperature caused by the presence of infectious viruses in rapid abortion channels, thus achieving the goal of avoiding virus transmission.

• processing systemThe motherboard is installed inside the chassis and fixed back-to-back with the display screen. It consists of a high-speed CPU, capacitors, resistors, inductors, and crystal diodesCrystal transistorComposed of integrated circuits and other components, it has the characteristics of high wiring density, light weight, thin thickness, and good safety, and is a component of the overall measurement response time center.
• display screenAdopting Resolution128*64The main function of the dot matrix LCD display screen is to quickly refresh the temperature values of the human body surface detected by the display sensor in real time, and it is equipped with film protection to ensure clear and intuitive values. The temperature display range is 35 ℃ -42 ℃. When no one passes by, it displays "Lo", and when the surface temperature of the human body is above 42 ℃, it displays "Hi".
• Sensor:

3.2 The sensor itself can simultaneously measure the ambient temperature and the surface temperature of the human body.

The sensor substrate temperature is measured by PTAT, and all sensor control and data processing are processed on the chip. The linearized sensor chip temperature Ta can also be read from the new product memory. The calculated temperature has a resolution of 0.02 ℃, and the linearized substrate temperature reading is stored in the 006h register of RAM at address 0 × 06

-0 × 06=0 × 4DE4 (19908d) corresponds to+125 ℃ (upper limit of linearized output)

Ta[°K]=Tareg×0.02,or0.02°K/LSB.

The output result is stored in RAM at a resolution of 0.02 ℃. The calculation of To is as follows:

• Alarm device:The alarm device consists of an alarm indicator light and a voice module. When the surface temperature of the human body detected by the infrared temperature screening device is higher than the set alarm value (default alarm value set by the factory is 37.5 ℃), the sound and light alarm function is automatically turned on: the light flashes+voice broadcast, and the broadcast content is "high body temperature+real-time temperature value". For example, when the detected surface temperature of the human body is 37.8 ℃, the broadcast content is: "High body temperature, body temperature 37.8 ℃".
• Chassis and bracket:

5.2 The bracket is available in two options: lateral bracket and lifting bracket. Both brackets are made of corrosion-resistant stainless steel material, which is transparent throughout and has a beautiful overall structure. The lateral bracket adopts fixed stainless steel seamless square tube; The lifting bracket adopts a lifting stainless steel seamless round tube. Both types of brackets are equipped with anti slip movable square chassis.
