Detailed Description

The invention will be better understood by the following description of embodiments thereof, but the applicant's specific embodiments are not intended to limit the invention to the particular embodiments shown, and any changes in the definition of parts or features and/or in the overall structure, not essential changes, are intended to define the scope of the invention.

As shown in fig. 1, the main idea of the present invention is to utilize a network terminal node to implement internet of things interconnection through an internet of things card and a mobile router, wherein a network access control system of the internet of things is responsible for managing the internet of things card in a unified manner. The internet of things network access control system is the prior art, and the ordinary technology of internet of things network access control can be realized by the aid of ordinary technical knowledge in the field mastered by technicians in the field. For the router terminal of the IOT card, equipment activation is completed firstly, the equipment state is reported to the control server after the equipment activation, and the IOT card equipment is monitored and managed through the server system.

The embodiment discloses application of various internet of things devices including cash register devices and monitoring devices, in order to enable network devices in the internet of things to be interconnected and intercommunicated, a plurality of programmable devices are arranged in the internet of things, communication protocols commonly used in industries such as modbus, PPi and the like are supported, the internet of things devices CAN be in butt joint with various industrial devices in an RS485, RS232 or CAN bus mode, instruction data sent by an internet of things cloud platform CAN also be received, corresponding analysis is carried out after the instruction data are received, the instruction data are sent to workers to be processed according to analysis results, the devices in the internet of things CAN carry out standardized processing on the field data in real time, the field data transmitted by a plurality of adapters in the internet of things CAN be received simultaneously, and the field data of various different types CAN be obtained on the basis of meeting platform specifications. The normalization processing mainly comprises: data analysis, data storage, data sorting and classification, correlation of different types of data, establishment of logic rules and the like. The internet of things cloud platform or the internet of things network access control system can also provide the stored field data to a higher-level application system, such as a monitoring server.

As shown in fig. 2, the timing sequence of the present invention is:

2) the server receives the teaching version of the person transmitted by the IOT card, records the reported state data of the IOT card, or: actively inquiring and configuring the state of the Internet of things, wherein the content of the state of the Internet of things comprises current flow inquiry and Internet of things disconnection;

In the network access control implementation process, the normalized field data can be obtained from the internet of things network access control system, and the field data is subjected to big data analysis and processing. The Internet of things card can report state data to the server periodically, and meanwhile, the server can actively inquire and configure the state of the Internet of things card: such as querying current traffic, disconnecting the internet of things card, etc. The background limits network access through uniformly configuring the white list, when the terminal equipment initiates a network request, only the request matched with the white list rule is allowed to pass and corresponding network data is returned, network requests which cannot be matched are intercepted, and the terminal cannot receive a network packet returned by a response.

The internet of things network access control system sends processed data to various types of terminal equipment, such as a computer, a smart phone or a large-screen terminal, workers, auditors, operation and maintenance personnel and the like can visually observe network access conditions in a browser login mode or a graphical interaction interface watching mode, and data analysis processing results are displayed on a background in various modes such as graphs, tables or curves, so that the problems that traditional broadband access is difficult and partial scenes do not support wide access to stores are solved.

The method comprises the steps that a terminal device operated by a terminal user initiates a network request, a network packet is sent to a server of an Internet of things network access control system, the Internet of things network access control system judges whether to allow the terminal user or the terminal device to use the flow of an Internet of things card according to a preset white list rule, the Internet of things network access control system judges whether to be matched with the rule according to the white list and an access rule thereof, if the terminal user or the terminal device conforms to the preset white list rule, the terminal user or the terminal device is allowed to access, and if the terminal user or the terminal device does not conform to the preset white list rule, the Internet of things network access control system makes corresponding judgment and rejects the flow of the terminal user or the terminal device accessing the Internet of things card.
