In Hangzhou, with a citizen card, you can enjoy such services as **, public bicycle rental, public library borrowing, and business union payment. In 2012, the in-depth use of the citizen card enabled the Hangzhou citizens to taste the sweetness of the “smart city.†The opening of the 4G network and mobile terminals has enabled Hangzhou to ride the “Smart City†train on the information superhighway. The rise of smart cities has accelerated the development of the Internet of Things. At the same time, it has broadened the field of application of security systems, allowing the security industry to transition from a traditional security system to an intelligent security system based on the concept of modern services. Its applications are all over Wisdom Medical. , smart campus, smart community, smart tourism and other fields.
I. Application of Internet of Things security in smart communities
Providing a warm, safe and convenient modern and intelligent living environment for community residents is the ultimate goal of a smart community. The equipment and platform are the traditional advantages of security companies. After the early entry into the “Peace Communitiesâ€, the original video surveillance system was expanded to the Internet of Things platform, combining community and home sensors, wearable devices, and community entrance management systems for modernization. Community management, smart big data applications provide infrastructure solutions. The application of IoT security in each subsystem is infiltrated with the concept of "intelligence" and "integration".
(I) Perimeter alarm system
The security team in the community has problems such as incomplete control, prevention of blind spots and maintenance of equipment. Therefore, in order to avoid property damage and personnel injury caused by these loopholes, a variety of sensing technologies are used on the basis of existing security teams: video surveillance. Measurement alarms, infrared radiation, microwaves, cables, electronic fences, optical fiber and other perimeter alarm devices, combined with intelligent video surveillance systems, provide real-time access to site conditions and decisions.
(b) Vehicle access/parking management system
The entrances and exits of the community and the parking lot are the areas that are mainly guarded against. Combining radio frequency identification technology with video recognition technology to establish intelligent monitoring bayonet and real-time acquisition of human and vehicle movement trajectory information, which not only changes the single identification method, but also realizes the interaction between people, vehicles and bayonet, and can be connected. Into the social security system, to facilitate security inspections and inspections, and more importantly, to improve the accuracy and timeliness of combating illegal activities involved in vehicles, and better maintain social stability.
(3) Home Security Management System
The smart home security system consists of three parts. Among them, the home wireless sensor network, the Internet, and the monitoring terminal correspond to the perception layer, network layer, and application layer of the Internet of Things in turn. Security sensors generally include surveillance cameras, gas sensors, human sensors, infrared detectors, vibration sensors, door and window anti-theft detectors, and alarm buttons. They all serve as a node of a wireless sensor network, using Bluetooth, wifi, zigbee, etc. Wireless communication technology access, a large number of sensors in all directions to protect the safety of the family.
(4) Information Publishing System
Community management personnel can publish various kinds of information through the display in the community and mobile phones, so that residents can learn about news and current affairs at home and abroad, financial information, various notifications and services within the community, and provide platforms for information exchange and sharing.
In addition, mobile devices such as mobile phones and platform computers have become an integral part of the security of the Internet of Things. When an illegal invasion, fire or gas leak occurs, the smart sensor will send out an alarm signal and pass the signal to the residential property management center, alarm center, and residents' mobile phones through the family center, informing the security personnel to rush to the scene in time. At the same time, residents can remotely monitor and visualize intercom via mobile devices such as mobile phones and tablet computers.
Second, the Internet of Things penetrates into all aspects of smart life
With the infiltration of the concept of the Internet of Things and the inevitable demand for the development of the information age, the application of the Internet of Things gradually began to appear in the personal application market, and the trend of civilian use became more apparent. This, to a certain extent, symbolized the increasingly mature development of the Internet of Things industry, and smart home, The smart life is becoming more integrated. What aspects of the Internet of Things have penetrated today?
(I) Smart Medical: Medical Intelligence Monitoring System
The WIT120, the wisdom medical treatment, is a medical term that has only recently emerged. General smart medical care consists of three parts: the smart ** system, the regional health system, and the family health system. At present, the family health system is not very popular. However, due to problems such as difficult medical care, difficult registration, and unbalanced distribution of medical resources in the society, smart medical systems can play a very effective role in improvement, so the wisdom system and regional health The system is slowly moving into people's lives.
Take the medical intelligent monitoring system as an example: This is an intelligent system composed of electronic medical records, remote monitoring, electronic patrol house, remote ambulance, and mobile service. Through the establishment of personal electronic health records, patients in any one of the treatment can let doctors know their own history, inspection status, medication information, X-rays, laboratory results, etc., without repeating the diagnosis every time you stay at home. Repeated tests reduce the time spent on medical consultation and also reduce the reuse of medical resources. Through the 120 ambulance monitoring and remote ambulance, the ** staff can form wireless video surveillance through TD technology, understand the situation inside the ambulance at the first time, provide guidance for on-site rescue, and make full preparation for the response.
(B) Smart Campus: Campus Card
The campus in the information age is inseparable from the information management. Smart campus generally takes campus card as the core content. In a radio frequency card, various functions such as student status management, daily consumption, identity authentication, and online payment can be realized. Because of unified management, campus cards are easier to implement than city cards, which is very conducive to the improvement of campus information management. The accumulation of problems and experience found in the operation of the campus phone card can provide the city card with the first-line support.
(III) Smart Consumption: Traceability and Smart Payment
The personal consumer market is one of the most dynamic markets. Therefore, the application of the Internet of Things in smart consumption will bring a lot of energy to the Internet of Things market.
With the increasing awareness of food safety, many products have gradually begun to use traceability codes. Consumers can trace every process of the production of a product on its own proprietary label, and play a role in controlling quality and supervision to some extent. As early as 2004, Yili began a system for traceability of infant milk powder. The initial use of digital code was to manually collect data. By 2006, one-dimensional code was used. In 2011, it began to use two-dimensional codes.
Smart payment can be said to be a hot technology product in recent years. Ali's "Payface Payment", Apple's fingerprint authentication (reporting that there is evidence that Apple intends to transplant fingerprint authentication technology to the latest iPhone's mobile payment application), Alipay and Yintai's attempt to scan code payments are all smart An attempt to pay. Smart payment not only applies offline, it also applies to online.
(D) Smart Home: Appliance Control
The forms of smart homes are relatively diverse and can generally be divided into home appliance control systems, lighting control systems, audio and video control systems, face recognition systems, door and window control systems, and security control systems. The home appliance control system is composed of a home appliance terminal, a control module, and a control platform software. The home owner can remotely control and manage home appliances at any time through a mobile phone or a computer, such as: indicating the operation of the washing machine, checking the food storage condition in the refrigerator, checking whether the gas is Close and so on. In the future, even without the instructions of the householder, “Internet of Things refrigerators,†“Internet of Things TVs,†and “Internet of Things kitchen appliances,†will automatically use the optimal configuration and interaction of home appliances according to the wishes of the homeowner.
Third, the conclusion
The core of the Internet of Things is business and application innovation. The in-depth integration of IoT technologies and intelligent technologies has accelerated the intelligent development of the industry and prompted the industry's demand to fall on the application layer. The integration of modern security and the Internet of Things in business and technology has undergone a dramatic chemical reaction, resulting in new values, more intelligent, more integrated, so that the core value of the security industry can be demonstrated.
