Wireless data acquisition and monitoring system based on 3rd generation (3G)/Beidou satellite communications and geographic information system (GIS)

Abstract

The invention discloses a wireless data acquisition and monitoring system based on 3G/Beidou satellite communications and a GIS. The system comprises a site collection monitoring device and system software. The collection monitoring device is connected with a signal collection circuit through a microcontroller to achieve signal collection, the microcontroller is connected with a relay control circuit to achieve real-time control, the microcontroller is connected with a mini camera circuit to achieve site monitoring, the microcontroller is connected with a solar circuit to achieve continuous supply of electric power, and the microcontroller is connected with a 3G communication circuit and a Beidou satellite communication circuit to achieve wireless remote transmission of data. The system software comprises a network data server and GIS-based client side software. The site collection monitoring device is in wireless connection with the server and a remote client side respectively through a wireless network communication system. The site collection monitoring device collects sensor signals on site, controls a device which is connected with a relay side and transmits signals collected through camera shooting to a server side in real time through a 3G network.

Description

technical field [0001] The invention belongs to the technical field of wireless data collection and monitoring of water conservancy, electric power, petroleum, chemical industry, production, manufacturing, industrial and mining, pipeline, environment, meteorology and transportation. [0002] Background technique [0002] The data acquisition and transmission methods used in the field of industrial control technology mainly include wired transmission methods, digital radio transmission methods, GSM / GPRS wireless transmission methods, RF wireless transmission methods, and Zigbee wireless transmission methods. The wired transmission method is mainly connected to the device through the serial port for corresponding data monitoring, and the transmission distance is short; the digital radio transmission method requires an external power supply or a large-capacity battery to supply power due to the need to set up a radio station, and the transmission distance is limited. The appl...
