Background
With the rapid development of the Internet, especially the mobile Internet, and the continuous breakthrough of sensing technology, more and more people are beginning to discuss the Internet of Things. Internet of Things technology is also applied in more industries. For the security industry, Whether networking will become the next vent is worth looking forward to.
The Internet of Things is not an unfamiliar concept. As early as 2000, the concept of the Internet of Things has been proposed. Its definition is: through information recognition devices such as radio frequency identification, infrared sensors, global positioning systems, laser scanning, etc. Any item is connected through the Internet of Things domain name for information exchange and communication, thus enabling intelligent identification, location, tracking, monitoring and management.
2. The application of the Internet of Things in the security industry
The domestic security industry, especially in the field of video surveillance, has solved the problem of “visible and clear†after more than ten years of development. It is entering the stage of “understand and understandâ€, to solve this problem, only through video. Means are difficult to solve, and IoT technology can greatly improve recognition results and efficiency. At present, the Internet of Things technology has been well applied in the fields of intelligent transportation, smart supervision, intelligent business, smart medical, smart home and so on.
Intelligent Transportation: Since the 1990s, China has started to develop intelligent transportation systems. After 2000, with the development of domestic security technology, the application of the embedded integrated machine to replace the industrial computer + camera has pushed the application of video surveillance in the traffic field to a climax. With the safe city, intelligent transportation project landing, bayonet system, electronic police system, traffic signal control system, traffic guidance system, pedestrian red light system, indecent pedestrian system, etc. all over the place, all these systems are almost relying on video, combined Image recognition algorithm, through the tracking of license plates, body colors, vehicle brands, etc., to achieve a variety of business applications.
Although these systems have greatly improved urban traffic management and public security management, they are still affected by some environmental and behavioral factors, such as rain and snow, foggy days, fake cards, decks, etc. With the Internet of Things technology, these problems can be solved more efficiently and accurately, such as through electronic license plate technology.
The electronic license plate is an application based on the subdivision, extension and improvement of the IoT passive radio frequency identification technology. Its basic technical measures are: using RFID high-precision identification, high-accuracy acquisition, high-sensitivity technical features, on the motor vehicle The last electronic license plate label, the RFID electronic license plate is used as the carrier of the vehicle information, and when the authorized radio frequency identification reader/writer section is installed, the data on the electronic license plate of each motor vehicle is collected or written to reach each The purpose of comprehensive traffic management.
Through the electronic license plate technology, it can break through the bottleneck of the original traffic information collection technology, realize the classified collection and accurate collection of vehicle traffic information, and grasp the key to the accurate information source of the traffic control system. At present, in Wuxi, Nanjing, Shenzhen, Xiamen, Chengdu and other regions have taken the lead in the use of electronic license plates, electronic license plate applications will also improve traffic efficiency and improve travel comfort.
Wisdom Supervisory Office: At present, the management of the Supervisory Office mainly stays in the stage of prison guard inspection + camera surveillance and alarm. The manual operation still accounts for a large proportion, and the degree of informatization is relatively low. It is difficult to achieve real-time supervision of detainees in the institution. Can not play the role of active prevention and early warning. In order to ensure the management level of the supervision office, improve the monitoring status of the detainees, improve the efficiency, and avoid the lag of security accidents, the combination of video surveillance and IoT perception makes the intelligent construction of the information of the supervisory office further.
By wearing a wristband-type electronic tag for each detainee, after entering the monitoring area, the electronic tag will continuously send the ID information, and the card reader installed in the monitoring area reads the tag ID and transmits the information to the back end. Application system to achieve real-time monitoring of the location of detainees. When an accident occurs, the scene and personnel position can be quickly viewed through video and wristbands, and the prison guards can be dispatched to the scene of the accident in time to improve the overall information management and safety management level of the supervisory office.
