In Hangzhou, with a citizen card, you can enjoy “one card” services such as medical insurance, public bicycle rental, public library borrowing, and business alliance payment. In 2012, the in-depth use of citizen cards allowed Hangzhou citizens to taste the sweetness of “smart cities”, and the opening of 4G networks and mobile terminals allowed Hangzhou to accelerate on the information superhighway by “smart city” trains. The rise of smart cities has accelerated the development of the Internet of Things. At the same time, it has broadened the application areas of security systems, enabling the security industry to transition from traditional security systems to intelligent security systems with modern services as its concept. , smart campus, smart community, smart tourism and other fields.

First, the application of the Internet of Things security in the smart community

Providing a warm, safe and convenient modern and intelligent living environment for the community residents is the ultimate goal of the smart community. Equipment and platform are the traditional advantages of security companies. After the initial entry of “Safe Community”, the original video surveillance system expanded into an Internet of Things platform, combining community and home sensors, wearable devices, and community access management systems for modernization. Community management, intelligent big data applications provide infrastructure solutions. The application of IoT security in each subsystem is infiltrated with the concept of “intelligence” and “integration”.

(1) Perimeter alarm system

The community security team has problems such as incomplete control, blind spot prevention and equipment maintenance. Therefore, in order to avoid property damage and personal injury caused by these vulnerabilities, a variety of sensing technologies are used on the basis of existing security teams: video surveillance. Measurement, infrared, microwave, cable, electronic fence, fiber optic and other perimeter alarm devices, combined with intelligent video surveillance system, real-time access to the scene and decision-making.

(2) Vehicle access/ parking management system

The entrances and exits of the community and the parking lot are the key areas for prevention. Combining radio frequency identification technology with video recognition technology, establishing intelligent monitoring bayonet, real-time access to the motion track information of people and vehicles, not only changes the single identification mode, but also realizes the interaction between people, cars and bayonet, and can be connected. Entering the social security system, it is easy to conduct security inspections and control, and more importantly, it improves the accuracy and timeliness of combating illegal activities involving vehicles, and better maintains social stability.

(3) Family Security Management System

The intelligent home security system consists of three parts. Among them, the home wireless sensor network, the Internet, and the monitoring terminal correspond to the sensing layer, the network layer, and the application layer of the Internet of Things. Security sensors generally include surveillance cameras, gas sensors, human sensors, infrared detectors, vibration sensors, door and window anti-theft detectors, and alarm buttons, all of which act as a node in a wireless sensor network, using Bluetooth, wifi, zigbee, etc. Wireless communication technology access, a large number of sensors to ensure the safety of the family.

(4) Information release system

Community managers can use the display screens in the community to publish various information on the mobile phone, so that residents can keep abreast of news and current affairs, financial information, various notifications and services provided in the community, and provide platforms to realize information interaction and sharing.

In addition, mobile devices such as mobile phones and platform computers have become an integral part of IoT security. In the case of illegal intrusion, fire, gas leakage and other abnormal conditions, the intelligent sensor will send out an alarm signal, and pass the signal to the residential property management center, the alarm center, and the resident mobile phone through the family center, and notify the security personnel to arrive at the scene in time. At the same time, residents can remotely monitor and visualize intercom through mobile devices such as mobile phones and tablets.

Second, the Internet of Things penetrates all aspects of smart life

With the infiltration of the concept of Internet of Things and the inevitable demand for the development of the information age, the application of the Internet of Things has gradually begun to appear in the personal application market, and the trend of civilization has become more and more obvious. This indicates to a certain extent that the development of the Internet of Things industry is becoming more mature, with smart homes , Smart life is getting more and more integrated. What aspects of the Internet of Things have penetrated today?

(1) Smart Medical: Medical Intelligent Monitoring System

Wisdom medical abbreviation WIT120 is a medical term that has only recently emerged. General smart health care consists of three parts: the smart hospital system, the regional health system, and the family health system. At present, the family health system is not very popular. However, due to the prevalence of medical difficulties, registration difficulties, and uneven distribution of medical resources, the smart medical system can play a very effective role in improving, so the smart hospital system and the regional health system. Slowly entering people's lives.

Piezoelectric Buzzer For Driver Circuit Built-in

The piezoelectric buzzers (for Driver Circuit Built-in) offer optimal sound, performance, and efficiency for all types of medical and industrial applications. Our piezo buzzers are constructed in a variety of sizes and work across varying frequencies which allows them to produce different sounds and tones. As voltage is applied to a piezo Buzzer, the piezoceramic disc vibrates, flexing with respect to input voltage to generate sound. Our piezo buzzers maintain low current draw which is advantageous for any battery operated device. Since piezo buzzers don`t have a magnet in their construction, it eliminates EMI/EMC issues.
