Intelligent building monitoring system based on Android and power carrier

Abstract

The invention relates to an intelligent building monitoring system based on Android and power carrier. A power line serves as a medium to transmit data packets. The system comprises control ends, a concentrator and multiple terminals, wherein the control ends comprise a PC control end and a mobile phone control end; the PC control end and the concentrator are connected via a serial port line for transmitting data; the mobile phone control end and the concentrator are connected via a GSM network for transmitting data; and the concentrator and a lower-stage terminal are connected via the power line for transmitting data. Defects of strong noise interference, large signal attenuation, randomness, time variation and the like in the case of carrier communication of a low-voltage power line can be overcome. Power carrier wired communication and GSM wireless communication are combined, advantages are enhanced and disadvantages are avoided, advantages of each are made full use of, the communication range is expanded, interference is reduced, the PC end is used for monitoring, multiple aspects such as inner dynamic point monitoring, theft prevention, alarming, and temperature monitoring of the intelligent building are realized, and a regional intelligent building monitoring network is further developed into a wide-area intelligent building monitoring network.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to an intelligent building monitoring system based on Android and power carrier. Background technique [0002] With the improvement of science and technology and the rapid development of information technology, people's living standards have been significantly improved, and the requirements for intelligent management of homes, office buildings, factories, etc. are also getting higher and higher, and the emergence of smart phones and mobile Internet, further accelerated this trend. Modern communication methods are mainly divided into two categories: wired communication methods and wireless communication methods. In terms of wired communication, the traditional wired communication adopts the method of pulling network cables. This method needs to build a special communication channel, so it requires a lot of manpower and resources. If the network cable is pulled into the room, it ...

AI Technical Summary

Problems solved by technology

However, since my country's power infrastructure was initially built as a dedicated channel for power transmission, and in order to consider that it will be used as a communication network in the future, low-voltage power line carrier communication has inherent defects, especially the extremely harsh environment of power line channels

The disadvantages of low-voltage power line carrier communication mainly include strong noise interference, large signal attenuation, randomness and time-varying, etc.
