(the picture shows safety training for drivers with the help of virtual reality technology.) No matter who we are, how we live and where we work, we benefit from technology every day. For example, science and technology will make communication and transactions between people more convenient and efficient, help to improve work efficiency and ensure people's work and production safety. People have a wide variety of workplaces: offices, warehouses, construction sites, retail stores, highways, etc. different work environments bring different risks, but some technologies can ensure the safety of most work and production occasions, including many "online celebrity" technologies, and the technology blog bettertechtips In the latest report, com listed three "net red" technologies that can protect people's work and production safety. wearable devices Wearable devices bring huge benefits to people in the industrial environment. Wearable devices have different shapes and sizes. They can be small devices like watches, hard hats or safety vests. Wearable devices can track employees' body temperature, heart rate and air quality in the workplace, so as to ensure the safety of employees. In the warehouse or construction site, wearable equipment can also act as protective equipment to prevent workers from getting too close to dangerous equipment or vehicles, and also help prevent accidents related to fatigue, stress or unsafe working environment. For example, Audi, a German automaker, has been using exoskeleton ergonomic aids to support workers when carrying heavy loads. It has been proved that these functions can reduce the back pressure of workers by 20-30% and keep them in a healthy posture for a long time. Moreover, such devices increasingly support the Internet of things, enabling occupational health professionals to use more accurate data more effectively through the correct regulatory protocols. In addition, during the outbreak of the COVID-19, several enterprises, including one of the world's largest auto parts manufacturers, multinational logistics companies and food suppliers, began to distribute the wearable chip SafeZone provided by the German start-up kinexon to workers in Germany, the United States and Switzerland, so as to track and ensure their health and safety. This small sensor was originally used by Chicago Bulls and other teams to monitor players' movement data in real time, so as to "transform" it into a sharp weapon to prevent the second outbreak of the epidemic in the factory workshop. If an employee is confirmed to be infected with COVID-19, the management can track the employee's action and alert the contacts. UAV More and more large companies and enterprises are using UAVs in the production process to help eliminate the risk of staff performing certain tasks, and ensure the safety of employees and surrounding residents by finding problems faster and even solving problems remotely in some cases. For example, in the oil refining and petrochemical industry, Michael Burnside, a policy analyst at the American Association of fuel and petrochemical manufacturers, pointed out that the purpose of using UAVs in petrochemical and oil refining enterprises can be divided into two categories: safety and protection. In terms of safety, the UAV can maintain the safety standards of the enterprise, such as visual inspection of the outside and inside of the flare stack or storage tank, and can also perform work that may be dangerous to people. In terms of protection, many companies set up road signs around the devices so that UAVs can fly around according to the predetermined route. The UAV is equipped with a camera, which can ensure that there are no holes in the perimeter fence. For example, ExxonMobil's Baton Rouge refinery has used UAVs equipped with high-definition cameras for comprehensive inspection, which is very helpful to reduce maintenance costs and ensure the reliability of the whole plant. UAVs can also be used to complete the collection of important data. For example, gischer sadanlacher, general manager of GE's oil and gas business, once pointed out that it used to take three weeks to collect and analyze data from robots. Now their UAV technology can report the data to operators in real time so that they can analyze it immediately. Virtual reality security training Virtual reality technology has now become a popular technology in the scientific and technological community. Many giant companies have laid out their plans one after another. One of the most widely used fields of this technology is safety education and training. By establishing a virtual scene to restore the event process, virtual reality technology can enable the experiencer to deeply experience the impact of various events from the visual, auditory and tactile aspects, so as to produce a lasting deterrent. The research shows that using virtual reality technology for training, the retention rate of memory knowledge can reach 80% after one week, while the traditional way is only about 20%. In addition, virtual reality can enable students to repeatedly simulate certain catastrophic scenarios without paying additional fees, so it can significantly reduce the training costs of enterprises. Oliver Pierre, CEO of French "immersion factory", a developer of security training content based on virtual reality technology, said that virtual reality technology can realistically restore the real working environment, which is very helpful to improve and optimize enterprise security behavior. For example, in the training, virtual reality technology can simulate a building under construction for employees, so that employees can immerse themselves in the fall caused by wrong construction. The dizziness, fear and other feelings brought by this strong and real sense of weightlessness can make employees deeply understand the serious consequences of illegal operation. According to the report on the official website of ThyssenKrupp Elevator Company, the company has integrated virtual reality technology into safety training as early as 2018: Elevator maintenance technicians can "enter" the real scene and learn safety and technical knowledge intuitively, vividly and efficiently simply by wearing virtual reality equipment; It can also deal with the maintenance problems that may be encountered in reality in the virtual reality world. If the operation is improper, it will simulate the experience of production safety problems such as "electric shock" and "falling from height", and practice without any personal danger. Coincidentally, UPS announced to increase its training courses for drivers, including the training institutions in Cologne, Germany and the virtual reality training program in Burton, UK. They use virtual reality helmets to simulate the driving experience on the streets of German and British cities, so that drivers have an unforgettable driving experience. (Xinhua News Agency)
