Remote power supply control switching system based on narrowband internet of things and remote power supply control switching method thereof

Abstract

The invention discloses a remote power supply control switching system based on the narrowband internet of things. The system comprises a power supply input bus, a power supply output bus and a remote control power supply switching device. The remote control power supply switching device comprises a core control unit, a power supply changeover switching module and a narrowband internet of things communication module. The core control unit comprises an encryption/decryption module, a state inspection module, a security detection module and a standard instruction production module. The narrowband internet of things communication module is connected with a background control center through a communication base station cellular network. The background control center is connected with an operation terminal. The invention also provides a control method. The remote power supply control switching system has better advantages than those of the conventional power supply control switching system in the aspects of application field, response efficiency, equipment energy consumption, coverage capability, application cost and security performance.

Description

Technical field [0001] The present invention relates to the technical field of power control switches, in particular to a remote power control switch system and method based on narrowband Internet of Things. Background technique [0002] With the continuous development and changes of corporate financing development needs in recent years, financial leasing plays an increasingly important role in the corporate financing process. By using movable fixed assets as the subject matter, the financial leasing business has become an important alternative way for enterprises to realize loan financing with traditional real estate mortgage, which is especially helpful for small and medium enterprises to obtain financing support from financial institutions in the process of purchasing equipment. In recent years, financial leasing has received encouragement and support from the state and governments at all levels. [0003] The corresponding physical objects of the subject matter in different ind...

Problems solved by technology

[0005] In the trial process of existing industries, financial leasing companies, with the cooperation of equipment manufacturers, have realized the function of searching, positioning and submitting to a certain extent by installing GPS modules and GPRS modules on equipment and vehicles, but this method often has the following Disadvantages: (1) There are limitations in network coverage, especially in basements, underground parking lots, etc., where the existing communication signal coverage is incomplete or the signal strength is insufficient, which limits the use in such scenarios; (2) It is impossible to implement equipment, The power supply of the vehicle can be controlled remotely, especially it is impossible to start and stop the power supply of equipment and vehicles; (3) rely on external power supply, the technical solution adopted by the existing monitoring module needs to be connected to an external power supply Or a larger volume of battery can achieve continuous work, which cannot meet the requirements of 1 year or even longer independent running time
