With the continuous deepening of the concept, connotation, technology, and application research of the Internet of Things, many typical cases of the Internet of Things applications have emerged in the fields and industries of the environment, power, logistics, and public safety. Among them, the public safety field, as a key field of IoT applications, has different characteristics and special status from other IoT applications. It is necessary to treat the IoT applications in the public safety field (hereinafter referred to as secure IoT) as an independent concept. In-depth study.
1 Background and connotation of secure Internet of Things
At present, China is in a period of rapid development of industrialization and urbanization. Various traditional and non-traditional, natural and social risks and contradictions coexist, and the situation facing public safety and emergency management is more severe. There are three main problems: 1) Natural disasters are in a period of frequent occurrence. In recent years, extreme climate events have occurred frequently, moderate and strong earthquakes are active, natural disasters and their derivatives, and the suddenness and harm of secondary disasters The safety situation is grim, the safety production foundation in China is weak, the responsibility of some localities and enterprises is not implemented, supervision is not in place, the total number of production safety accidents remains high, and serious accidents occur from time to time to prevent accidents. The task of carrying out effective rescue is arduous and arduous; 3) Social security is facing new challenges. China's reform and development have entered a critical stage. Various interest relationships are complex and the task of maintaining social stability is arduous.
In the face of frequent public safety accidents that cause a large number of casualties and property losses, it is urgent to build a public safety monitoring Internet of Things to perceive the hidden dangers of public safety, and to solve the problems of how the various departments interconnect and interoperate after emergencies.
The public safety monitoring Internet of Things is applied to the characteristics of wide coverage of the public safety monitoring field, many monitoring indicators, high continuity requirements, the environment is not suitable for manual monitoring, and the perceived information content is closely related to the lives of the people. Especially for sensor network technology, an information system project composed of perception layer, network layer and application layer is constructed. The monitoring of public safety mainly includes the monitoring of the security of various production scenarios, the monitoring of the safety of producers, the monitoring of the safety of specific items, the monitoring of personnel-intensive places, the monitoring of important equipment and facilities, and the monitoring of scenes and personnel during accident emergency handling. , Information collection of items, etc.
2 The status of the secure Internet of Things in the development of the Internet of Things
Public safety is the cornerstone of national security and social stability. In order to effectively resist the threat of various man-made or natural disasters, China has made strengthening public safety guarantee measures a priority of the government's work. The public safety monitoring Internet of Things provides a new way of thinking to solve the public safety problems facing China, which is in line with China's strategic requirements to promote scientific and technological innovation and take the development path of an innovative country.
The establishment of a perfect public safety monitoring Internet of Things will provide a practical and effective prevention mechanism for the safety problems such as bridge tunnel collapse and dangerous substance leakage that our country is facing. The interconnection of the national public safety monitoring Internet of Things has made major security incidents timely and Powerful and transparent solution. Therefore, as the Internet of Things application in the field of public safety that is most closely connected with daily life and most concerned by the country and the people, the Internet of Things for public safety monitoring should be valued and prioritized by the entire society, insisting on "government-led, enterprise participation, social support, and mass "Benefit" policy, through the development of public safety monitoring Internet of Things to bring the progress of animal networking in technology, application, industry, standards, so that the entire society feels the public safety monitoring of the public security hidden dangers of public safety and reliable prevention and sudden The advantages of emergency response to incidents strengthen people's awareness of the value of the Internet of Things.
