Wireless data collection and control device based on 3G (third-generation telecommunication)/Beidou satellite communication technology

Abstract

The invention discloses a wireless data collection and control device based on a 3G (the third-generation telecommunication) / Beidou satellite communication technology. The wireless data collection and control device comprises an on-site collection end integrating 3G communication and Beidou communication and a receiving control end formed by connecting a Beidou receiving end with a personal computer (PC) client-side, wherein the receiving control end is used for achieving data reception and transmission of control instructions. The on-site collection end integrates a Beidou module, a 3G module, a control module, a liquid crystal display (LCD) touch screen display module, a collection module, an isolation module and other auxiliary modules and the like to achieve data transmission and instruction reception. Six functions such as data collection, remote control, 3G communication, Beidou communication, Beidou positioning and Beidou time service are effectively integrated through the wireless data collection and control device, intelligent switching between the 3G communication and the Beidou communication is achieved, and the wireless data collection and control device can simultaneously work in areas with base station signal coverage and remote areas without base station signal coverage.

Description

technical field [0001] The invention can be applied to the fields of water conservancy, electric power, fishery, forest fire prevention, disaster relief and prevention, meteorology, oil and gas, environmental monitoring, etc., and specifically relates to a long-distance wireless data acquisition and control device that is not limited by base station signal coverage. Background technique [0002] At present, the main data acquisition and transmission methods used in the fields of water conservancy, electric power, fishery, forest fire prevention, disaster relief and prevention, meteorology, oil and gas, and environmental monitoring include wired transmission, digital radio transmission, GSM / GPRS network transmission and the use of Other means of HF channel and VHF channel transmission. Wired transmission mode, its transmission rate is slow, the laying of lines is troublesome, and it is not suitable for long-distance transmission. In addition, when encountering disasters such ...

AI Technical Summary

Problems solved by technology

Wired transmission mode, its transmission rate is slow, the laying of lines is troublesome, and it is not suitable for long-distance transmission. In addition, when encountering disasters such as wind, rainstorm, etc., once the line is broken, the information cannot be uploaded and released in time, and the stability is relatively poor; The disadvantage of the radio transmission method is that the long-distance transmission consumes a lot of power, and the transmission distance is greatly affected by the environment; while the GSM / GPRS network transmission method is not real-time and must rely on the GSM mobile network, if the remote and wild base station signals cannot be completely covered It is difficult for data to be transmitted stably or normally; both shortwave and ultrashortwave are also difficult to adapt to long-distance transmission and harsh working environments.
