Problems solved by technology

[0006] (1) The recording method is mainly in analog mode, even if it is recorded in digital mode, it is difficult to conveniently input it into the computer for processing
[0007] (2) The processing is basically judged by manual processing, which is time-consuming and error-prone
[0008] (3) The collection, transmission, and processing of hydrological information are poor in real-time and accurate, and cannot meet the needs of modern hydrology
When using a telephone line to transmit data, the speed is slow and the cost is high because of the need to wait for each dial-up
At the same time, due to the wide distribution, large number and long distance of each monitoring point, some points are still located in remote places, so many telephone lines need to be applied for, and some monitoring points are difficult to reach with wired lines

Abstract

The invention discloses a hydrological data acquisition and transmission system of a public network based on a GPRS (general radio packet service) network, which mainly comprises a hydrological sensor, a GPRS data transmission device, the GPRS network, the Internet and a data center connected sequentially. The data center comprises a modem, and the modem is connected with the Internet. The invention has the advantages that: 1, the reliability is high; 2, the real-time performance is high; 3, the collection and reading scope is wide; 4, the system construction cost is low; 5, the system operating cost is low; and 6, the system transmission capacity is high.

Description

technical field [0001] The invention relates to hydrological survey and report, specifically, a public network hydrological survey and report system based on GPRS network. Background technique [0002] With the development of my country's economy and society, new requirements are constantly put forward for hydrological information, and the items and contents of hydrological observation are constantly increasing, which puts forward higher and higher requirements for the research and development and application of observation means and methods as well as hydrological monitoring technology; modern electronic technology, The rapid development of sensing technology, communication technology and computer technology has also promoted the development of hydrological monitoring technology automation. [0003] In the hydrological monitoring system, it is often necessary to monitor many water points in real time, and most of the monitoring data need to be sent to the back-end server of ...
