“At the end of 2019, the new coronavirus began to spread in Hubei Province. Since the outbreak began in January 2020, people’s daily work and lifestyle have undergone major changes.
At the end of 2019, the new coronavirus began to spread in Hubei Province. Since the outbreak began in January 2020, people’s daily work and lifestyle have undergone major changes.
From all kinds of material assistance in the early stage of the outbreak, to the subsequent national stay at home, national prevention and control, and now the epidemic control has gradually stabilized, and work and production have begun to resume. We can see that the Internet of Things technology is used in all aspects. A better application to help solve various problems in the epidemic.
Network infrastructure accelerates to help “national supervision”
In the early days of the outbreak, in Hubei Province, especially Wuhan City, due to the surge in the number of confirmed cases, isolation beds became the most scarce resource. Under the call of the country, Huoshenshan, Leishenshan and various makeshift hospitals began to be built at a miraculous speed. , so that people around the world are amazed by the speed of China’s infrastructure construction.
During the period, “National Supervisor” became a hot search on Weibo for a while, and people who stayed at home watched the construction process of Vulcan Mountain and Leishen Mountain online.
The Internet of Things video surveillance solution built through the network camera (IPC) + the operator’s 5G line + the cloud manufacturer’s cloud storage makes this live broadcast, which has tens of millions of attention, possible.

Taking telehealth a step further
After the outbreak, in order to prevent non-fever-related patients from going to the hospital and reduce the risk of cross-infection with potential new coronary pneumonia patients, remote consultation and telemedicine solutions have been launched in various places.
More remote consultations are still moving some common diseases online. During the peak period of the epidemic, millions of doctors across the country offered free online consultations to help these non-pneumonia-related patients solve their medical problems.
And telemedicine has also played a very important role in the diagnosis of this epidemic. Experts from all over the country do not have to go to the local hospital in Hubei. Through remote consultation, they can help some difficult cases to analyze and diagnose, which greatly improves medical care. diagnostic efficiency.

With the popularization of 5G technology, the cellular network provided by it has been greatly improved in terms of stability and bandwidth, and remote consultation will gradually become popular in hospitals, even in some operating rooms, in some key parts. In the research stage, experts can also be accessed through the remote consultation system to solve problems in the operation together.
“Contactless” technology strengthens community prevention and control
In terms of community epidemic prevention and control, the power of non-governmental organizations can be said to be strong, their execution power is outstanding, and they have contributed a lot of “contactless” good ideas. Let’s take a look at which Internet of Things technology is used in community prevention and control. solution.
01 Forehead Thermometer
It is essentially a thermal infrared sensor that collects the temperature of the human body in a non-contact way to provide decision-making data for access control managers (or systems).
Now some face recognition access control systems also support face recognition (with adjustment algorithms for masks) and temperature detection. After these “perception layers” collect data, they are transmitted to the server through the network for decision-making, and finally decide to release and no.
The Internet of Things integrates the perception layer, the communication layer, the computing layer and the decision-making layer here, providing a smarter solution without arranging a large number of people to do repeated temperature measurement. It is only necessary to carry out secondary confirmation processing for abnormal personnel, which has a wide range of applications whether it is in community management or in the resumption of production and work in industrial parks.
02Home staff management
Home management for people with relevant contact history in some key epidemic areas is also an important part of community epidemic prevention and control. The cruder plan is to physically block the doors of the relevant personnel, which has caused dissatisfaction among many blocked people and even led to more contact-based conflicts.
At present, there are two common solutions that can easily and safely monitor at home:
The first is the door sensor IoT solution. The door sensor is installed on the entrance door. When the door sensor senses movement, it connects to the server through its low-power cellular network (NB-IoT), and issues an alarm to the supervisors and supervisors. Take action to on-site inspection to confirm.
Another way is to use an IP camera (IPC), by installing an IP camera at the entrance of the supervised person. In order to facilitate wiring, wireless WiFi or 4G network is generally used for networking. The camera side integrates AI technology to perform mobile monitoring of the door. When an abnormality is found, an alarm is sent to the supervisor, and a voice alarm can be played at the same time. achieve a dissuasive effect. This method can achieve high-efficiency, no-contact, and zero-dead-end community prevention and control.

03 Drone Patrol
During the peak period of the epidemic, drones were deployed in some places for the patrol of some scattered people on the road. The drone is equipped with a camera, and the camera transmits the video to the monitoring background through the 4G/5G network. The supervisor can patrol remotely through the monitoring background. After patrolling the abnormal personnel, the voice speaker on the drone will be notified through the network to play the alarm content to achieve remote control. The effect of dissuasion saves a lot of manpower on street patrols.
Promote the smooth resumption of production and work of enterprises
At present, the prevention and control of the epidemic has stabilized. As of February 27, the number of new confirmed cases has reached single digits in other regions of the country except Hubei, which is basically controllable. All localities have also begun to resume production and work one after another. economic work.
In the context of the epidemic, the resumption of production and work should also pay attention to safety prevention and control to prevent crowds from gathering and causing the epidemic again. Therefore, the original main battlefield of prevention and control has been transferred from the community to the industrial park.
From the forehead thermometer to the face recognition and temperature measurement all-in-one machine, the Internet of Things technology is making efforts. The traditional armpit mercury thermometer takes 5 minutes to measure body temperature once, 10 seconds to the ear thermometer, and 5 seconds to the forehead thermometer. The face remote thermometer can handle dozens of people at the same time every second, saving every step. With the time for testing, the orderly resumption of production and work has gradually been on the right track.
It is also worthy of appreciation that the health QR codes launched by some Internet giants based on years of big data analysis and credit data accumulation have also played a significant role. The health code seems to be simple to apply, but the background will verify the information submitted by the applicant through big data analysis, and it is also strongly bound to the credit reporting system, which can effectively prevent people from fishing in troubled waters and is worthy of nationwide promotion.

At present, some companies that do access control and offline distribution are already developing products that combine the health code with the original system. Putting the inspection of the health code online can further improve efficiency. In the case of full resumption of production and work Therefore, it will not cause missed work and other disputes due to the efficiency of testing.
Another problem to be solved in the resumption of production and work is the problem of employees’ dining. The original employees’ meals may be takeaways, dining out, and corporate meals. However, the outbreak of the epidemic has caused many catering stores to be unable to provide normal services, and everyone is concerned about it. The point is still “no contact”.
Whether it’s takeout or express delivery, everyone needs “contactless” services. Before the outbreak of the epidemic, there were express cabinets developed based on the Internet of Things technology. It is a “contactless” service, but it is not enough. No contact also requires a safe and hygienic environment. Therefore, some manufacturers of catering self-collection cabinets have developed With the “non-contact” self-collection cabinet with disinfection ability, the cabinet can be automatically sterilized by high temperature or ultraviolet light to meet the needs of dining and make the resumption of production and work smoother.

It can be seen that before, during, and after the epidemic prevention and control, the Internet of Things technology plays a very critical role. The epidemic also puts forward higher requirements for the development of the Internet of Things, especially for the Internet of Things based on 5G cellular mobile. will usher in its explosion.
It has been about 20 years since the concept of the Internet of Things was proposed. Its development is also inseparable from the development of the Internet and the mobile Internet. Slowly, these networks are also integrating with each other. In fact, people are increasingly distinguishing which are the Internet of Things. , which are the Internet, there is no need to distinguish, in the long-term future, the Internet of Things and the Internet of people will continue to integrate, and finally the Internet of Everything will be truly realized, and people’s living standards will be improved by more levels.
