Description
Technical Field
The invention relates to the technical field of Internet of things, in particular to a digital monitoring safe access method and device based on a narrow-band Internet of things.
Background
The Internet of Things (IoT) is a network world with Things connected. The IoT connects objects through technologies such as communication and cloud computing to meet people's living needs and support social operations.
With the development of the 'cloud and object movement' technology, more and more internet of things systems (technologies) are applied to electric power scenes, and an asset life-span lean management system which takes object identification as a core and comprehensively utilizes new technologies such as internet of things, mobile application, big data and the like is basically built. Typical internet of things systems in asset management projects include an internet of things platform, a cable channel monitoring system and the like. Meanwhile, products such as a vehicle management system, an electronic intelligent lock, a video monitoring network and the like widely used by a power grid company at present can also be understood as an internet of things system.
In general, from the business, the technology of the internet of things is widely used in the power industry; however, in terms of technology, because the development of technology is different from the corresponding safety protection level of each system, the safety protection work of the internet of things system in the power industry still needs to be strengthened, and a plurality of problems still exist, such as:
1. there is a safety risk in monitoring systems such as cable trench detection on-line. The front-end sensor and the acquisition unit of the existing cable channel monitoring system lack identity authentication, and if the acquisition unit is connected in a wired mode, information content cannot be accessed due to lack of a safety protection means, so that the information content becomes an information isolated island; if the acquisition units are connected in a wireless mode, a PKI certificate needs to be adopted to access through the security access platform, the acquisition units are required to have higher computing capacity, and the security access platform cannot support mass equipment. Therefore, the traditional security access platform cannot meet the requirement of the existing service for new addition.
2. Some video monitoring systems such as cameras have security risks. The main body is as follows: bypass monitoring (others access a video network to perform onlooker monitoring or store video), network intrusion (an attacker borrows a wired network of a camera to intrude an information intranet), and unauthorized user viewing (unauthorized users view video through a system of a monitoring center such as NVR). In summary, the current smart sensors (e.g., cameras) lack new technical validation and instructional construction standards.
