Take the upcoming Shanghai World Expo as an example. According to the forecast of relevant departments, there will be 400,000 tourists every day during the Shanghai World Expo, of which about 340,000 will dine in the Expo Park. Ensuring food safety has become an important task in Shanghai. "When food enters the park, law enforcement officers can quickly trace the sources of food and raw materials on the spot through the mobile devices holding office terminals to ensure the safety and reliability of supply channels. At the same time, RFID labels will be required to be worn on the packaging bags of primary agricultural products such as vegetables, fruits, aquatic products, eggs, semi-finished food and beverage products, and information such as breeding enterprises or production units, product names, places of origin, production dates, shelf life and storage conditions will be marked. Will be stored, so that product packaging and RFID tags can completely enter the catering, retail or commodity trading logistics terminals, ensuring the traceability of food and raw materials.
The fire alarm equipment to be used in the World Expo has also attracted the attention of many citizens. In the LA 100 fire safety monitoring system demonstration area, we see that the new fire safety monitoring system can imitate the human eye and nose system to monitor a large space. According to reports, the so-called "eye" refers to the "electronic eye", which can monitor the space in real time, while the "nose" is an induction system. Once smoke is found, it will send back a signal to the system. At present, this monitoring system has been installed in six pavilions of the Shanghai World Expo.
In addition, it is worth mentioning that in the Wenchuan earthquake, the real-time dynamic information of the dammed lake was exchanged through "network+sensing technology"-related information was transmitted to the decision-making department in the rear through the sensor network (also a kind of generalized Internet of Things), effectively avoiding the risk of casualties that people may encounter in field observation. As one of the applications of Internet of Things products, automated home is no longer a passive building. Instead, it has become a tool to help the owner make full use of time and make the home more comfortable, safe, efficient and energy-saving.
Smart home, or smart residence, is an efficient, comfortable, safe, convenient and environment-friendly living environment based on residence, integrating architecture, network communication, information appliances and equipment automation, and integrating system, structure, service and management. Smart home can also be defined as a process or a system, which uses advanced computer technology, network communication technology and integrated wiring technology to organically combine various subsystems related to home life, and make home life more comfortable, safe and effective through overall management. Compared with ordinary homes, smart homes not only have traditional living functions, but also provide comfortable, safe, high-grade and pleasant family living space. It has also changed from a passive static structure to a tool with dynamic wisdom, providing a full range of information exchange functions, helping families to keep information exchange smooth with the outside world, optimizing people's lifestyles, helping people to arrange their time effectively, enhancing the safety of home life, and even saving various energy costs.
When you are outside, a short message can make your home automatically cook, or automatically turn on the air conditioner and water heater; In the smart home environment, when you get home and the door lock is unlocked, your home security system will automatically remove the indoor alert, the corridor lights will light up slowly, the air conditioning fresh air system will automatically start, and your favorite background symphony will play gently. At home, you only need a remote control to control all the appliances in your home. Every night, all the curtains will be closed automatically at regular intervals. Before going to bed, touch the "good night" mode on the bedside panel to control all the lights and electrical equipment in the room that need to be turned off, and the security system will automatically turn on and be on alert.
Smart home system can not be separated from home automation, home network, network appliances and information appliances. Home automation refers to the use of microprocessor electronic technology to integrate or control home electronic products or systems, such as lighting, coffee stoves, computer equipment, security systems, heating and cooling systems, video and audio systems. The home automation system mainly uses a central microprocessor to receive information from related electronic and electrical products, such as changes in external environmental factors, such as changes in light caused by the rising or setting of the sun, and then sends appropriate information to other electronic and electrical products with established procedures. The central microprocessor must control household appliances through many interfaces, which can be keyboards, touch screens, buttons, computers, telephones, remote controllers and so on. Users can send signals to or receive signals from the central microprocessor. Home automation is an important system of smart home. When smart home first appeared, home automation was even equivalent to smart home. Today, it is still one of the cores of smart home. Intelligent transportation is the frontier of international transportation, which promotes the integration and application of information, communication, control, new energy and automobile technology on the transportation platform and causes revolutionary changes in all aspects of transportation. As a multi-disciplinary and multi-industry system engineering, Intelligent Transportation involves all aspects, from data collection to system integration to platform operation, security companies have more opportunities to cut in.
Intelligent transportation industry is closely related to security industry, and a large number of security products need to be applied in intelligent transportation system, such as urban public traffic management and urban road traffic management. Urban intelligent public transport system is an intelligent system mainly aimed at the command, management, scheduling and emergency of urban public transport. Urban intelligent bus system mainly realizes the comprehensive monitoring of urban bus lines, stations and vehicles. Predict and reasonably dispatch public transport resources through various auxiliary equipment to optimize public transport system.
Urban road management system includes signal light control system, road condition indication system, license plate recognition system and road video monitoring system. Signal light control system and road signs are mainly to help management departments and vehicles better understand the road conditions, so as to carry out the most reasonable road management and road selection and improve the efficiency of road transportation. License plate recognition system and road video monitoring system not only improve the efficiency of road transportation, but also play a certain role in urban public safety monitoring. Among the above systems, the road video monitoring system is the most widely used system. In the construction of "safe cities" in many cities, road video monitoring has been included in the scope of construction. At present, more advanced hospitals have actually come to the front in the application of mobile information. For example, it can realize real-time recording, transmission, processing and utilization of medical record information, patient information, illness information and so on. , so that relevant information can be enjoyed in real time and effectively through the networking within and between hospitals, which can play a good supporting role in realizing the information flow of telemedicine, expert consultation, hospital referral and other processes. The development of mobile medical information, whether for hospital management, doctor diagnosis or nurse care, will be an optimal state of mobile information development and a direction of future efforts.
In addition, judging from the current development of medical informatization, with the increasingly obvious development trend of community and medical care in recent years, it will become more and more important for the future development of medical informatization to realize real-time diagnosis and health reminder for patients in hospitals or sub-health patients through the effective operation process of the Internet of Things.
Internet of things technology can still play a great role in the application of drug management and drug use. According to statistics, medical accidents in the United States rank fifth among the causes of death, and foreign adverse drug events rank first among all non-surgical medical negligence. Through the Internet of Things technology, information such as drug name, variety, origin, batch, production, processing, transportation, storage and sales are stored in RFID tags, and problems can be traced back to the whole process. At the same time, this information can be transmitted to a public database, and patients or hospitals can compare the contents of the labels with the records in the database, thus effectively identifying counterfeit drugs. Intelligent environmental protection is to embed sensors and equipment into various environmental monitoring objects (objects) with the help of Internet of Things technology, and integrate the Internet of Things into the environmental protection field through supercomputers and cloud computing, which can realize the integration of human society and environmental business systems, and realize the intelligence of environmental management and decision-making in a more refined and dynamic way. Environmental monitoring is the earliest and most mature application field of Internet of Things technology. In the mid-1990s, with the rapid development of China's economy, problems such as excessive discharge by enterprises and deterioration of ecological environment quality began to stand out. In order to protect the environment, environmental protection departments at all levels, from central to local, began to actively explore the use of legal, administrative, economic and technical means to strengthen environmental supervision. As the dominant technology of the new industrial wave, the Internet of Things has become the focus of attention all over the world.
Application case: In order to help the government deal with the crisis of cyanobacteria in Taihu Lake, Chinese Academy of Sciences put several sensing devices in Taihu Lake. Once the cyanobacteria rise, or the water temperature changes, and there is a possibility of cyanobacteria outbreak, the sensor will issue an early warning in time, so that the decision-making organs can get information in time and make a response. In environmental monitoring, in case of gas leakage, water pollution and other events, the staff can carry a box of biochemical sensors with them, which are randomly distributed within a certain range like sowing. Dozens of sensors can be wirelessly networked to "track" the diffusion path of harmful substances at any time and "send messages" to the headquarters in real time.
