At home, you only need one remote control to control all the appliances in your home. Every night, all the curtains will automatically close at a scheduled time. Before going to bed, you can touch the "Good Night" mode on the panel next to the bed to control all the lights and electrical equipment in the room that need to be turned off. At the same time, the security system will automatically turn on and be on alert. A smart home system is inseparable from the four major product combinations of home automation, home network, network appliances, and information appliances. Home automation refers to the use of microprocessing electronic technology to integrate or control electronic and electrical products or systems in the home, such as lighting, coffee stoves, computer equipment, security systems, heating and air conditioning systems, video and audio systems, etc. 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 sun, etc., and then sends appropriate messages according to established procedures. information to other electronic and electrical products. The central microprocessor must control the electrical products in the home through many interfaces. These interfaces can be keyboards, touch screens, buttons, computers, telephones, remote controls, etc.; users can send signals to the central microprocessor machine, or receive signals from a central microprocessor. Home automation is an important system of smart homes. When smart homes first appeared, home automation was even equated with smart homes. Today it is still one of the cores of smart homes. Intelligent transportation is the forefront of the development of today's international transportation field. It promotes the integration and integrated application of information, communications, control, new energy and automotive technologies on transportation platforms, causing revolutionary changes in all aspects of the transportation field. As a system engineering involving multiple disciplines and industries, intelligent transportation involves all aspects from data collection to system integration to platform operation, and there are more opportunities for security companies to enter.

The intelligent transportation industry is very closely related to the security industry. A large number of security products need to be applied in intelligent transportation systems, such as urban bus traffic management and urban road traffic management. The urban intelligent public transportation system is an intelligent system mainly aimed at the command, management, dispatching, emergency response and other aspects of public transportation within the city. The urban intelligent public transportation system mainly realizes comprehensive monitoring of urban public transportation lines, stations, and vehicles. Predict and rationally dispatch public transportation resources through various auxiliary equipment to optimize the public transportation system.

Urban road management systems include signal light control systems, road condition indication systems, license plate recognition systems, road video surveillance systems, etc. The signal light control system and road condition signs mainly help management departments and vehicles better understand the road conditions in order to carry out the most reasonable road management and road selection, and improve the efficiency of road transportation. In addition to improving road transportation efficiency, license plate recognition systems and road video surveillance systems also play a certain role in urban security monitoring. The road video surveillance system is the most widely used system among the above systems. In the construction of "safe cities" in many cities, road video surveillance has been included in the construction scope. At present, more advanced hospitals have actually gone to the forefront in the application of mobile informatization. For example, real-time recording, transmission and processing of medical record information, patient information, condition information, etc. can be realized, so that relevant information can be shared in real time and effectively within and between hospitals through networking, which is very important for The informatization process that realizes telemedicine, expert consultation, hospital transfer and other processes can play a very supportive role, and the development of mobile informatization in medical informatization, whether it is for hospital management, doctor diagnosis, nurse care, or patient Medical treatment and other work will create great convenience. The Internet of Things will be an optimal state for the development of mobile informatization and a direction for future efforts.

In addition, judging from the current development of medical informatization, as the development trend of community-based and health-care medical and health care has become increasingly obvious in recent years, if physical sign information is collected at home through radio frequency instruments and other related terminal equipment, Real-time tracking and monitoring, through the effective operation process of the Internet of Things, the hospital can realize real-time diagnosis and health reminders of patients or sub-healthy patients, thereby effectively reducing and controlling the occurrence and development of patients, which is very important for medical and health care. In terms of the future development of informatization, it will become increasingly important.

Internet of Things technology can also play a huge role in the application process of drug management and medication. Data once showed that medical accidents ranked fifth in the cause of death in the United States, and adverse drug events in foreign countries ranked first among all non-surgical causes. Medical negligence ranks first. Through IoT technology, drug name, variety, place of origin, batch and information on production, processing, transportation, storage, sales and other links can be stored in RFID tags. When a problem occurs, the entire process can be traced. At the same time, the information can also be transmitted to the public database, and patients or hospitals can compare the content of the label with the records in the database to effectively identify counterfeit drugs. Intelligent environmental protection uses Internet of Things technology to embed sensors and equipment into various environmental monitoring objects (objects), and integrates the Internet of Things in the field of environmental protection through supercomputers and cloud computing to achieve the integration of human society and environmental business systems. Realize the wisdom of environmental management and decision-making in a more refined and dynamic way. Environmental monitoring is the earliest and most mature field of application of Internet of Things technology. In the mid-1990s, with the rapid development of my country's economy, the problems of excessive pollution discharge by enterprises and deterioration of ecological environment quality began to become prominent. In order to protect the environment, environmental protection departments at all levels from the central to local levels have begun to actively explore the use of legal, administrative, economic, and technical means to strengthen environmental supervision. As a new industrial wave leading technology, the Internet of Things has become the focus of attention around the world.

Application case: In order to help the government respond to the cyanobacteria crisis in Taihu Lake, the Chinese Academy of Sciences has placed a number of sensing devices in Taihu Lake. Once cyanobacteria rise, or the water temperature changes, and there is a possibility of a cyanobacteria outbreak, the sensors will promptly send out Early warning, so that decision-making agencies can receive timely information and respond. In environmental monitoring, if incidents such as gas leakage or water pollution occur, workers can carry a box of biochemical sensors with them and scatter them randomly within a certain range like sowing seeds. Dozens of sensors can be wirelessly networked to "track" harmful substances at any time. spread path and "report" it to the headquarters in real time.
