Data transmission and remote control method for self-organizing wireless internet of things (IoT) system

Abstract

The invention provides a data transmission and remote control method for a self-organizing wireless internet of things (IoT) system. The data transmission and remote control method disclosed by the invention has the advantages that: firstly, communication code addresses and communication flows of a channel are saved in large quantities; secondly, the bottleneck of card number resource insufficiency of SIM (Subscriber Identity Module) communication cards is eliminated for the application of a mobile communication network on a IoT, and the access volume and the communication traffic volume of a terminal of the mobile communication network are sufficiently expanded; thirdly, an IP (Internet Protocol) address dose not need to be taken as a core of a self-organizing area network because a central base station and a PC (Personal Computer) machine are not connected with an external Internet, and therefore internal autonomous wireless communication is realized; and fourthly, even if a hacker invades the GSM / GPRS (Global System for Mobile Communication / General Packet Radio Service) mobile communication network, a user terminal can still not be invaded, and therefore the hacker and Trojan horse viruses can be effectively prevented from directly invading the user terminal.

Description

Technical field: [0001] The invention relates to the field of the Internet of Things, in particular to a data transmission and remote control method for an ad hoc wireless Internet of Things system. Background technique: [0002] At present, the existing technologies of the Internet of Things generally include: (1), its terminal sub-nodes (RFID, smart sensors, smart home appliances) + Internet = Internet of Things; (2), the sensors and gateways of its terminal sub-nodes are all wireless A wireless local area network (according to IEEE wireless communication technology) that the signal transceiver module communicates in a point-to-point manner, which is another type of Internet of Things that is a wireless local area network + Internet; (3), its terminal sub-nodes use GSM / The GPRS mobile communication module and SIM card are directly installed on the terminal equipment, and the user can use the mobile phone and the terminal equipment to conduct direct point-to-point communic...

AI Technical Summary

Problems solved by technology

[0003] To sum up, these are the currently known networking modes of the Internet of Things. The Internet of Things using (1) mode is equivalent to setting an IP address for each terminal device such as a sensor, a collector, and a home appliance controller, and then passing The Internet is used for data transmission and control, and as more and more terminal devices are connected to the network, the current IP address resources are limited, and it is impossible to meet the needs of things and people. It is connected to the Internet, so hackers or Trojan viruses are very easy to invade the user's terminal equipment from the Internet, and the security is poor; using (2) mode of the Internet of Things, the communication module on each sub-node needs to use a dialer to program the basic code address , and there must be an IP address on the user's network management, this method will also be limited by the code address and IP address; using (3) mode of the Internet of Things, because the terminal equipment controlled must be installed with GSM / GPRS mobile Communication module and SIM card, in this way, the bottleneck of insufficient resources of the SIM communication card number will plague the development of the Internet of Things, and the mobile communication network and terminal equipment are directly controlled, and hackers or Trojan horse viruses are also very easy to get out of the mobile communication network. Intrusion into the user's terminal equipment, poor security
