Self-powered multivariate distributed online monitoring system and method based on 3G/GSM network

Abstract

The invention discloses a self-powered multivariate distributed online monitoring system and method based on a 3G/GSM network. The system comprises a lower computer and an upper computer. The lower computer comprises a core control board, a DTU (a GSM module and a 3G module), various sensors, an external power source and a storage unit. An acceleration sensor, a stress sensor, a humidity sensor and a temperature sensor adopted by the lower computer are distributed at different monitoring points of an object to be monitored for monitoring the vibration acceleration, the stress surface stress, the surface humidity and the environment temperature of the object to be monitored. The external power source is used for supplying power to the units of the lower computer. The upper computer comprises a computer client and a mobile phone client, wherein the computer client can store and analyze information transmitted back by the lower computer and generate real-time graphs and monitoring reports, and the mobile phone client can control the lower computer at any time and any place. The self-powered multivariate distributed online monitoring system and method have the advantages that debugging is convenient, the working time is long, electricity and energy are saved, mobile control is achieved, and data can be intelligently processed.

Description

technical field [0001] The invention relates to the technical field of wireless sensing and communication, in particular to a self-powered multivariable distributed on-line monitoring system and method based on 3G / GSM network. Background technique [0002] Electric power engineering and water conservancy projects are important basic industries and public utilities related to the national economy and people's livelihood. Their safe and stable operation is an important guarantee for the comprehensive, coordinated and sustainable development of the national economy. [0003] Transmission lines, especially high-voltage overhead transmission lines, are the lifeblood of power systems, and their operating conditions directly affect the safety and stability of power grid operations. Natural disasters such as icing and typhoon are one of the common safety hazards of transmission lines. In recent years, with the emergence of extreme climates around the world, wind and ice disasters on...

AI Technical Summary

Problems solved by technology

However, it cannot provide continuous power supply for the monitoring equipment, does not solve the problem that the battery charging circuit cannot be started due to the excessive battery power loss caused by long-term solar energy shortage and long-distance transportation of the equipment, and cannot maximize the detectable time range.

At the same time, long-distance transmission of data cannot be realized.

Does not have intelligent data processing functions and report generation functions, and cannot reduce the time for users to analyze data
