Networking type terminal controller and system based on Beidou satellite communication

Abstract

The invention discloses a networking type terminal controller and system based on Beidou satellite communication. The controller comprises an input unit, a central controller unit and a control unit; the input unit comprises a communication module, an electric energy management module and a lightning protection power supply input module, and the central controller unit is connected with the input unit and the control unit. The controller is simple in working principle, the terminal, the terminal controller, short-distance communication and the Beidou satellite communication system are reasonably combined together, the system can be used in a local environment, the networking control mode is flexible, remote networking can be achieved through Beidou satellite communication, and centralized control and distributed management are achieved.

Description

technical field [0001] The invention relates to the technical field of networked controllers, in particular to a networked terminal controller and system based on Beidou satellite communication. Background technique [0002] The controllers in the prior art are mainly based on the single control mode, renting a small-scale local area network through a simple short-distance communication mode, the structure is relatively simple, the transparent transmission mode is adopted, the security is poor, the coverage area is small, and the function is single , the integrity is poor, and it cannot meet the application requirements of a wide range of scenarios; the existing communication control methods are all developed based on short-distance or mobile Internet technology, and mobile Internet support is required for use. In remote areas, the signal cannot be completely covered, or Without a signal, remote control and remote perception cannot be completed; the Beidou system has a wide ...

Problems solved by technology

[0002]The controller in the prior art is mainly based on the single control mode, renting a small-scale local area network through a simple short-distance communication mode, and the structure is relatively simple , using a transparent transmission method, poor security, small coverage, single function, poor integrity, and cannot meet the application requirements of a wide range of scenarios; the existing communication control methods are all developed based on short-distance or mobile Internet technology, and need to be used when using Mobile Internet support, in remote areas, the signal cannot be completely covered, or there is no signal, and remote control and remote sensing cannot be completed; the Beidou system has a wide coverage, communication is not restricted by natural environments such as regions and climates, and the communication success rate is high and reliable. Strong confidentiality, meeting the remote control needs of some special industries

[0003]The existing technology networks are basically short-distance, and the communication frequency is based on the public frequency band, which has large interference, narrow bandwidth, and low reliability; Geographical restrictions are relatively large, and it is impossible to achieve all-weather and long-distance control; the existing communication methods have poor confidentiality, and the communication lines use public network data, which is vulnerable to network hijacking and network attacks, poor confidentiality, and low reliability
